Editorial ITCRR – championing the research efforts of the community The international textile and clothing research register (ITCRR) is in its 13th year of publishing the research efforts of our community. It provides a breadth of activity in the field of textile and clothing research and it encourages participation and dissemination to those working in this discipline and further afield. Again as you will see in this new edition, textile and clothing research and practice is increasing in volume, in quality and in diversity – all good news for all of us involved in it. Research, development and innovation can, without doubt, give us more wisdom, enable our industries to become more competitive, and contribute to our quality of life. I believe that registering research projects will provide the due credit to originators of the research and contribute much more to the future development of this field. Groups of expertise can be identified in this manner, repetition and re-invention can be avoided leading to best utilisation of time and funding for faster and better directed research in the international arena. Important since globalisation is on everybody’s agenda. The ITCRR was set up with all these things in mind. Textiles and clothing originate from the physiological need to protect ourselves from the environment. This has made necessary the art of hand knitting and weaving, and cut and sew processes which have been evolving for many centuries. Although, the original need for clothing has somewhat changed, the mechanisation of this process started after the industrial revolution and has continued this century with automation developments on a massive scale. If you consider the upstream part of the whole textile and clothing production chain, yarn-making is the most highly automated area, followed by fabric, with high speed knitting and weaving machines. The downstream part of garment making, however, still remains probably the less developed connection in this chain; one that no doubt many of us have our eyes on as the candidate for development into the new century. With massive computerisation over the last 20 years, logistics and sales have also changed dramatically from pen and paper to electronic data interchange and electronic point of sale. New challenges are already upon us with nanotextiles, nanofibres, nanocoatings with multifunctional and smart textiles and clothing, and with wearable electronics. A special issue on smart textiles and clothing is at an advanced stage of development and we will continue to welcome contributions from textile and clothing aesthetics, design and fashion highlighting our belief that design and technology go hand to hand. We predict that more exciting projects will come from this synergy. Consistent and extensive research and development in textile and clothing design and science and technology underpin all these developments by the international research community whether in educational establishments, in research trade organisations, or in companies. IJCST was been set up 19 years ago as a platform for the promotion of scientific and technical research at an international level. The manufacture of clothing in particular needs to change to more technologically advanced forms of manufacturing and retailing – IJCST continues to support the community in these and other efforts. q Professor George K. Stylios.
The journal, now fully indexed in SCI, continues with its authoritative style to accredit original technical research and by adhering to our refereeing processes however difficult these may prove at times. IJCST will be instrumental in continuing to support conferences and meetings from around the world in its effort to promote the science and technology of clothing. The 2007 volume saw the publication of a double issue from “3rd International Textile, Clothing and Design Conference” Dubrovnik, October 2006. I finally praise the enthusiasm of our research community and those authors that have made IJCST an invaluable resource to all involved with textiles and clothing. I thank our editorial board for their continuous support and our colleagues who have acted in a refereeing capacity and have given us their free time and expertise to progress our research efforts.

International Journal of Clothing Science and Technology Vol. 19 No. 6, 2007 pp. 6-7 q Emerald Group Publishing Limited 0955-6222
Professor Blazˇ Knez, PhD, from the Faculty of Textile Technology, University of Zagreb, Croatia, a long-time member of the International Journal of Clothing Science and Technology Editorial Advisory Board, sadly died on 17 June 2007 after a long fight with illness. He was 79. Born in Libelicˇe, Slovenia in 1928 Professor Knez gained his bachelor’s degree at the Polytechnic of Belgrade and continued his graduate education at the Faculty of Technology and Metallurgy in Belgrade, graduating in 1968. From 1952 to 1959 he attended numerous specialisation courses in Germany and the USA and this rich experience enabled him to become chief engineer of the biggest Yugoslav clothing factories (BEKO Belgrade and Kamensko, Zagreb). After experience in industrial practice he moved into the education of experts in all the branches of garment technology and engineering. From 1973 to 1976 he was a Professor and Dean of the Professional College of Garment Technology in Zagreb, and from 1977 to retirement in 1990 a Professor at the Faculty of Technology and the Director of the Institute of Textile and Clothing, a part of that Faculty. He obtained his PhD from the Faculty of Technology, University of Zagreb, Croatia in 1980. To promote higher education in the field of garment engineering together with his collaborators he founded the Department of Clothing Technology and Engineering. This facility has two research laboratories and is used as a centre for the university education of experts in garment technology in Croatia. He was the supervisor on over 400 graduate theses, 11 master’s theses and four PhD theses at the Faculty including the first PhD theses in garment engineering in Croatia. Professor Knez was the author of over 130 original scientific papers and took part in 43 international conferences with his contributions. It should be noted that his rich practical experience enabled him to lead 37 technological projects for founding garment manufacturing plants all over Croatia. As an educator, he published six university textbooks in the field and was the Chief Researcher of six scientific research projects funded by the Croatian Government. Professor Knez actively participated in the workings of scientific research magazines, and was a member of the editorial boards of the Tekstilna Industrija (Belgrade), Tekstil (Zagreb) and International Journal of Clothing Science and Technology (Bradford, UK). He was a member of professional associations in the field, as a board member mostly, and was the President of the organisation committees of four scientific/professional conferences. He was also a guest lecturer at the universities of Budapest, Lodz, Sofia and Moscow. His activity did not stop with his retirement – he was chief researcher of research projects and took part in constructing modern curricula for university courses in garment engineering.
The work and efforts by Professor Knez have significantly contributed to the development of textile and garment university courses in Croatia, as well as to shaping the profession and scientific field in Croatia and the whole of former Yugoslavia. His public lectures, projects on new garment manufacturing plants and his other work contributed immensely to the development of textile and garment industries in Croatia, while his participation in foreign publications and conferences contributed to the affirmation of garment engineering globally. He never hesitated to transfer his accomplishments and rich experience to generations of his students who are today top managers of garment manufacturers, university teachers and renowned experts not only in Croatia but also further afield.

Design and Development of Novel Compression Therapy Regimes for the Treatment of Venous Leg Ulcers Other Partners: Academic None
Industrial Vernon-Carus Ltd, Rossendale Combining Company Ltd Project end date: 23 October 2008
Project start date: 24 October 2005 Project budget: £152,142 Source of support: EPSRC Keywords: Compression therapy, Leg ulcers, Bandages
Venous leg ulcers are the most common type of ulcers and their prevalence increases with age. In the UK alone about 1 per cent of the adult population suffers from active ulceration during their life time. The total cost to the National Health Service in the UK for venous leg ulcers treatment is about 650 million per annum, which is 1-2 per cent of the total healthcare expenditure. Costs per patient have recently been estimated to be between £1,200 and £1,400. Venous leg ulcers are chronic and there is no medication or surgery to cure the disease other than the compression therapy. A sustained graduated compression mainly enhances the flow of blood back to the heart, improves the functioning of valves and calf muscle pumps, reduces oedema and prevents the swelling of veins. In the UK four layer bandaging system is widely used whilst in Europe and Australia the non-elastic two layer short stretch bandage regime is the standard treatment. Both the two layer and four layer systems require padding bandage that is applied next to the skin and underneath the short stretch or compression bandages. It is generally agreed by the clinicians that four layer bandages are too bulky for patients and the cost involved is high. A wide range of compression bandages is available in the Drug Tariff but each of them has different structure and properties and this influences the variation in performance and properties of bandages. The research carried out at the University of Bolton showed that there are significant variations in properties of commercial padding bandages, more importantly the commercial bandages did not distribute the pressure evenly at the ankle as well as the calf region. When pressure is applied using compression bandages, the structure of the nonwoven padding bandages collapsed and the bandages could not impart cushioning effect to the limb. In view of the above mentioned limitations and problems, it is vital that research and development

work should be carried out to design, develop and characterise novel single layer bandages that would effectively fulfil the requirements of both padding and compression bandages. It is recognised that spacer is the right technology to produce novel compression bandages that meet the prerequisites of both ideal padding and compression bandages. In three-dimensional (3D) spacer fabrics, two separate fabric layers are combined with an inner spacer yarn or yarns using either warp knitting or weft knitting route. It is possible to produce low modulus spacer fabrics by making use of elastic yarns. Elastic compression could be achieved by altering the structures. It should be mentioned that 3D structure allows greater control over elasticity and these structures can be engineered to be uni-directional, bi-directional and multi-directional. Uni-directional elasticity is one of the desired properties for compression bandages. The three-dimensional nature of spacer fabrics makes an ideal application next to the skin because they have desirable properties that are ideal for the human body. 3D fabrics are soft, have good resilience that provides cushioning effect to the body, breathable, ability to control heat and moisture transfer. For venous leg ulcer applications, such attributes together with improved elasticity and recovery promote faster healing.
Project aims and objectives .
To study in-depth the current practices and problems in managing venous leg ulcers.
.
To test and characterise the currently available commercial bandaging systems.
.

.
contributing to social stability through its representation across all the areas in the;
.
having a significant share in national economy export; and
.
contributing with a positive balance to foreign trade.
In Romania, structure of the enterprises in the textile field, in terms of employees’ number, presents as follows: total number of enterprises in the textile field: over 8,000. As easily seen above the number of textile SMEs represents around 96 per cent of the total number of enterprises in Romania. The Romanian Government is aware and appreciates the importance of these companies. The policy in the field of SMEs in Romania has become a part of the Regional Development Policy, due to the great role of the SMEs – “locomotives” of a sustainable economic growth, creating jobs and having an important role in fighting the unemployment. At present, the majority of Romanian enterprises in the textile field are not sufficiently prepared for responding to the opportunities and challenges that the accession to enlarged knowledge-based EU supposes. The innovation policy has as center the research-industry relation. Research creates markets, and industry’s needs generate new researches. ITA TEXCONF is created with the purpose of valorizing the results of technological research and development and, especially for the realization of technological transfer to SMEs. The institutional construction of a technologic and business incubator is a complex theme, this character being determined by the multitude of activities that must be carried out for acquisitions consisting of the endowing with the equipment necessary for carrying out the activity specific for the incubator centre, in order to provide a study to select the SMEs team which are going to be incubed. Relations between research and industry have to be dealt with based on a coherent, long term and comprehensive policy, which should incorporate as core element researchindustry connection through: .
marketing research results;
.
promotion of start-ups by researchers in the new technologies field;
.
creation of conditions favoring activities and partnerships transfer between research and industry;

A parameterized body model is evaluated. The model is appropriate not only for the symmetric and asymmetric body modelling but for motion simulation too. The real sizes of the human body can be defined by a photo based on reduced measuring processes or by robotized 3D scanning using re-engineering. We are developing an integrated traditional scanner and a 6D KUKA robot for scanning the visible and masked body parts. Shape and sizes of clothparts are derived from the geometry of the human body model. Designers modify the model and shape of parts in space. The shape of patterns is calculated by direct laying out. The mechanical model of clothes is a multi mass-point flexible mechanical structure. A virtual mannequin wears the model dress. Draping and texture behaviour is real-time simulated by the mechanical model. There is a newly evaluated drape tester equipment. Tester scans the 3D shape of parts and material properties are defined by the same simulation as used for the virtual mannequin.

Structural and strength modelling and complex testing of fibrous structures and fibre reinforced composites Other Partners: Academic

None BUTE Department of Information Engineering Project start date: 2005 Project end date: 2008 Project budget: 43000 euro Source of support: Hungarian Scientific Research Fund – OTKA T049069 Keywords: Modelling, Testing, Fiber bundles, Fibrous structures, Reinforcements, Composites Besides the fibers, fiber groups called fiber bundles as intermediate structural elements play an important role in the macro-scale behavior and properties of the fibrous structures such as slivers, rovings, yarns, webs, fleeces, fabrics, and reinforcements of polymeric composites. The Department of Polymer Engineering has dealt with testing textiles and fibrous reinforcing systems using image processing and with the theoretical fundamentals of their computational structural-mechanical modeling essentially for more than one decade. In the framework of some earlier projects (OTKA I/3 821, 1991-1994; OTKA I/5 T7652, 1993-1994) a novel modeling method [1-4] was developed applying the so
called idealized fiber-bundle-cells as structured statistical mechanical model elements to modeling fiber flows such as slivers or fiber bundles to flat bundle test or twisted fiber structures such as filament or spun yarns. In addition, in cooperation with the Research Institute of Technical Physics and Materials Science Budapest some geometrical and mechanical testing techniques [5-8] for measuring the diameter of fibers or yarns and the fiber orientation on webs or yarn surface as well as the local deformation of fabrics during tensile test were elaborated using image processing technology. The idealized fiber-bundle- cells [1,2,12] are statistical because the strength parameters of the fibers (tensile strength, breaking strain, initial tensile stiffness), and the bundle properties of the fiber cells (pretension, order), as well as the parameters for describing the grip of the fibers or fiber chains (slippage load, slippage length) are stochastic variables. From the sub-bundles combined, so called composite bundles or fiber bundle chains can be formed. According to the modeling concept a finite composite fiber bundle or fiber bundle chains or network built up of randomly or deterministicly oriented fibers ungripped or gripped at one or two ends can be the structural-mechanical model of a real textile considered concerning not only the increasing load but the damage process as well [1-4, 12-13, 16-17]. Another research work (OTKA T022077, 1997-1999) extended to the fiber reinforced composites focused on modeling the structure of glass fiber mats and testing the structural-mechanical properties of the one layer glass mat reinforced unsaturated polyester (UP) resin composite sheets. Besides the structural-geometrical model of short fiber structures developed [9-10] a testing method based on image processing was worked out for studying the local deformation and crack propagation of trans-illuminated composite specimens during tensile test. Using the mobile CCD camera image processing system developed in the framework of this project [5-6] the cracks coming into being during the tensile test were detected as fibers or edges and by that the fiber deformation and crack propagation processes could be described numerically by evaluating the fiber orientation histograms recorded [11]. The next project in this topic (OTKA T038220, 2002-2004) aimed mainly at testing and modeling the damage and fracture process of unidirectional carbon fiber reinforced epoxy resin composites during flexural test as well as analyzing the effect of the geometry. According to experiences the modeling method using statistical fiber-bundlecells can be describe the expected value of the bending load in an acceptable way even if the simplest fiber-bundle-cell was used and the breakage of the stretched layers were modeled [12-13]. The fiber-bundle-cells method was also applied to modeling the mechanical behavior of braided carbon fiber reinforced composite tubes subjected to tensile load [15]. Two PhD Theses made use of the results. The current research project (OTKA T049069, 2005-2008) undertook to summarize and complete the results of the structural-mechanical testing and modeling methods and work out some new applications, as well as – in collaboration with the Department of Information Engineering BUTE – develop a software package for modeling and a complex testing method including geometrical and mechanical tests, acoustic measurements and image processing [14,18]. This is the topic of a PhD Thesis and a DSc Thesis.

Solar cells in textiles Other Partners: Academic

None More Being sought Project start date: 2001 Project end date: Ongoing Keywords: Thin film silicon, solar energy, photovoltaics We are developing thin-film silicon solar cells on low cost textile substrates, using chemical vapour deposition (CVD) technology, based on previous thin-film diamond expertise. The CVD technology employs a proprietary microwave plasma system (developed at Heriot-Watt University) with silane/hydrogen/dopant gas mixtures to produce the sequence of layers that forms the active part of these cells. We have shown that relatively low deposition temperatures of 200 C and the active plasma conditions of the process do not affect our textile substrates, whether of woven or non-woven construction. In addition, solutions have been determined to the problem of providing reliable electrical contacts over fibrous, flexible substrates, together with a conventional transparent conducting oxide as the top contact in the cell “sandwich” structure. Effective “first barrier” encapsulation may also use our deposition technology.
Project aims and objectives Flexible solar cells for a variety of applications: e.g. building facades, use in remote areas, emergency use in disaster relief, camping/leisure industry, portable chargers.

The measurement and control of mean pressure delivery exerted by pressure garments for the treatment of hypertrophic scars Other Partners: Academic
Industrial
None None Project start date: September 2004 Project end date: September 2007 Source of support: EPSRC and Drapers Company Keywords: Pressure garment, Pressure measurement, Hypertrophic burn scars, Powernet fabric Pressure garments are the predominant treatment method for hypertrophic scars. They are constructed from elastic fabrics and are custom-made to suit individual treatment specifications. The properties of the elastic fabrics have an impact on the pressure delivery of the garments and ultimately determine treatment success. During this investigation 12 new pressure garment fabrics have been knitted using the powernet structure. Each fabric has a slightly different specification and by assessing certain fabric properties, the impact on pressure delivery of these fabrics can be established. The reduction factor, fabric tension and model circumference are the main properties that contribute to the pressure delivery of the fabrics; the relationships of which are being thoroughly investigated. The measurement of pressure delivery exerted by pressure garments to the wound site is very important. A mean pressure of 25mmHg has been regularly quoted as the optimum pressure required for treating hypertrophic scars. It has been established that when assessing the extent of pressure delivery to the patient, there is no scientific
method currently used by medical practitioners. Based on this information two sensor measurement systems are being developed and investigated for this project. The sensors are being used to measure the mean pressures exerted by pressure garment samples on cylinder models and have been incorporated into the construction of a pressure sensing mannequin which is a simulation of the male upper torso and left arm. Further measurements are to be taken from human volunteers and compared with the model analysis results. Throughout the investigation development work on a predictive equation for calculating pressure delivery of 25mmHg to small circumference limbs from pressure garments is being carried out.
Project aims and objectives .
.
Evaluate the pressures exerted to small circumference limbs and complex body shapes. Develop a pressure-sensing mannequin incorporating an accurate and reliable pressure measurement system to record pressures exerted by pressure garments.
.
Evaluate the effectiveness of 3D modelling for investigation between fabric specifications and applied pressure.
.
Establish relationships between powernet fabric construction variables and pressure delivery potential.

Our laboratory is using a process called electrospinning which has the ability to produce a wide variety of polymeric fibres with diameters from a couple of micrometer down to the nanometer scale. In this case different structures can be made from electrospun fibers to suit the needs of various industries. Electrospinning, a fibre spinning technique that relies on electrostatic forces to produce fibres in the nanometer to micron diameter range, has been extensively explored as a simple method to prepare fibres from polymer solutions or melts. Under the influence of the electrostatic field, a pendant droplet of the polymer solution at the spinneret is deformed into a conical shape (Taylor cone). If the voltage surpasses a threshold value, electrostatic forces overcome the surface tension, and a fine charged jet is ejected. As these electric static forces increase, the jet will elongate and accelerate by the electric forces. The jet undergoes a variety of instabilities, dries, and deposits on a substrate as a random nanofibre mat. In our work, nonwoven electrospun mats of nylon 6 produced from solutions with formic acid with different concentrations are examined. Each nonwoven mat with average fibre diameters from 200 to 1300 nm was prepared under controlled electrospinning process parameters. Effects of electric field and tip-to-collection plate distances of various nylon 6 concentrations in formic acid on fibre uniformity, morphology and diameters were measured. Processing parameters effects on the morphology such as fibre diameter and its uniformity of electrospun polymer nanofibres was investigated. A process optimization summarized the effects of solutions properties and processing parameters on the electrospun nanofibre morphology was issued. In our work, we Control the electrospinning process to move away from just collecting random fibre mesh to enabling the accurate deposit of fibres at any predetermined position. This will be by using a simple method of getting a fibres bundle made of aligned nanofibres between two known points. This collection process has been termed as the ‘gap method of alignment’ involves grounding two circular disks from the spinneret. We have demonstrated that it is possible to produce continuous fiber yarn made out of electrospun nanofibres. The current process has the potential to spin nanofibre at a commercially viable rate.

None None Project start date: July 2004 Project end date: June 2008 Keywords: Electrospinning, Electrospinning process, Parameters, Polymer, Nanofibre application Electrospinning is a unique way to produce novel polymer nanofibres with diameter typically in the range of 10 nm to 500 nm. Using this process, the polymer nanofibres can be made from a variety of polymer solutions or melt to produce fibres for a wide range of applications. Electrospinning occurs when the electrical force at the surface of a polymer solution or melt overcomes the surface tension and causes an electrically charged jet to be ejected. When the jet dries or solidifies, an electrically charged fibre remains. This charged fibre can be directed or collected or accelerated by electrical forces, then collected in sheets or other geometrical forms. This research project is an investigation of the electrospinning process and the effect of process variables on orientation, crystallinity, microstructure and mechanical properties of the nanofibres produced. Some of the polymeric parameters investigated are polymer type, solvent type, molecular weight, solution properties, viscosity, conductivity and surface tension. In the case of process parameters, the electric potential, flow rate, concentration, distance between capillary and collection screen, ambient parameters are important

Project start date: April 2006 Project budget: £650,000 Source of support: DTI Technology Programme Keywords: Micro-channel, Micro-porous, Membrane, Controlled delivery, Drug release
This project, which stems out of research findings of an EPSRC-funded research, aims at developing micro channel structures (coatings, membranes, foams, etc.) with encapsulated biopharmaceuticals capable of controlled release by changes in temperature, pH, magnetic field or voltage. A technique for encapsulating biopharmaceuticals into micro-channels of a polymer matrix structure and controlling their subsequent release will be developed. Driven by the consortium, the technologies will be veered towards various pay-load bearing applications, e.g. in self-supporting materials for delivering bone growth hormones (INN eptotermin alpha) in bone fractures, or in coated textiles for the personal hygiene, healthcare, treatment and protective clothing industries.
Project aims and objectives The main objectives for the projects are to: .
Establish criteria for channel size and distribution control; engineer the structure and morphology of the porous material to suit the encapsulation of biopharmaceuticals and their slow release. This involves both self-supported materials and coated textiles.
.
Investigate UV-based techniques for the encapsulation of specific biopharmaceuticals, with particular reference to bone growth hormones.
.
Investigate strategies for the controlled release of the biomaterials from the channels within the developed membrane or coating.

covering diverse applications of the outputs, attempting to represent this sector. OCF and Scotweave will help commercialising the output in the form of a software product or licence. The main aim of the project is to develop the models such that they can be used primarily by the high performance textiles and garment industry, but also by other industries dealing with flexible materials. The key strength of the proposal is that for the first time an attempt is made to model the behaviour of flexible materials in a 3D manner, taking into account the dynamic changes of performance related properties with physical changes during use. .
Bridging the gap between (a) industry needs for predictive and development tools and (b) academic modelling efforts on two levels: structure/property micro/meso scale and macro-scale whole flexible structures such as high performance clothing.
.
Modelling of overall properties and performance of simple deformed textile structures such as draped/creased/folded fabrics, predicting the dynamic changes of performance related to physical deformations. This will be an innovative engineering tool for industries involved in designing, developing and manufacturing flexible materials, initially targeted at fabrics, but with applications to paper and thin films.
.
Modelling simple high performance whole garments based on structural/geometrical parameters of the flexible materials, to predict the changes in whole garment performance caused by yarn and fabric changes. No model that can perform this function for the high performance clothing industry is yet available. This aspect of the work will be a powerful tool for the high performance clothing and garment industry (high performance medical wear, protective clothing, sportswear, etc.)
The project will lead to two way modelling: predicting properties and performance of deformed textile materials and whole garments from structural, mechanical and geometrical parameters, or vice versa, i.e. generating structural, mechanical and geometrical requirements for specific end-product characteristics. Focusing on the high performance clothing sector, the work will provide a first-in-its-kind tool for design, development, engineering and optimisation of high performance flexible materials and exploited by a consortium of diverse companies, three of which are technology providers and the rest users of the technology. Different mechanisms (e.g. interfacial modification) can be exploited in the manufacture, modification, cleaning and care of high performance multi-component textiles. This will permit rational design of these materials and associated products, reducing the need for experimental development and testing. This project will push the boundaries in multi-scale modelling by building on leading edge expertise in fibre to yarn scale modelling at Manchester University, yarn to textile scale modelling at Nottingham University, and textile to whole flexible structures and clothing at Heriot-Watt University. By developing and interfacing these areas closely coupled tools will allow completely predictive models to be developed. It will also be the first time that modelling techniques have been used to understand the effects of interfacial properties on textile performance, leading to increasing innovation in high performance textile products.
Project aims and objectives .
Combining the strong modelling expertise of the four academic partners to create multi-scale integrated models for predicting structural properties and performance of flexible materials.
.
Optimising the integrated models for industry use, focusing in the first instance at high performance clothing and technical textiles.
.
Increasing time and cost efficiency of industry in product design and fabrication, starting with the high performance clothing industry.
.
The objectives address industry needs for new and improved product design and fabrication aids for high performance materials e.g. in view of the London 2012 Olympics (high performance sportswear, anti-terrorism protective clothing, etc.). They will enable the prediction of properties and performance before manufacturing, hence accelerating the development stage, reducing costs and increasing competitiveness.

achieved through continuous competence building and the development of a common terminological platform. Consequently companies and institutions of education will join forces in an International/European network to develop a common platform for knowledge-sharing by establishing a combined online terminology database and visual training system. The International/European dimension is needed in national training in companies and for students at textile/design schools who are to take up positions in companies operating worldwide. At production sites the database will provide in annovative teaching tool for competence building. The partners will involve the knowledge and competences of their own institutions in a collaboration where their expert knowledge within the various stages of the value chain from raw material to finished product will complement each other. Given the sheer scope and limited time span of the project and to ensure quality, the project will cover terminology in the stages from raw material to sem-finished product in English, German and Danish. Subsequent projects will extend the database from semimanufactures to finished articles and extend the database into other languages.

None Dr R Annable, Dr J Pearson, Ms P Macbeth Project start date: June 2005 Project end date: April 2007 Keywords: Ink jet printing, Craft, Colour management, Simulation of craft techniques There are many techniques in textile crafts which are virtually impossible to produce commercially, for example hand and computer generated embroidered textiles and hand knotted woven fabrics. With the growing interest in the consumer market in the UK particular for textile craft products, it is becoming increasingly important to develop reproducible techniques to enable these products to be made to a commercially acceptable level. With the capability of ink jet printing being able to print at high resolution and in almost true colour, it is possible to simulate these techniques on fabric. In doing so, accurate colour representation must be achieved; the method of colour management used will be examined. This research describes the steps required to obtain identical images of the textile craft onto a CAD system, with the correct resolution, number of colours and size. This research is also pushing the boundaries of what is possible to print on using textile ink jet technology and pre-manipulated fabrics. Using a variety of fabrics that previously have not been able to print using ink jet technology; looking into custom treating and the possibility of fixing pigment inks.
Project aims and objectives The aim of this research is to achieve an accurate representation of hand-developed craft techniques using CAD software and textile ink jet technology, and to study the problems that may arise with this and to produce high quality printed fabric results. They will need to be commercially viable and in doing so the beginnings of a catalogue will be generated allowing for choice in custom made printed textiles. The process will be documented for future production of simulated craft techniques onto printed fabrics, resulting in the discussion of the use of colour management, CAD software and potential uses.

Dr S. Ghosh None Project start date: 1 April 2004 Project end date: 30 September 2007 Project budget: Rs 15 LACS Source of support: Ministry of Human Resource Development, India Blankets are generally woven or knitted and are made from pure wool or blends of wool and acrylic fibres. Woven or Knitted fabric production is a lengthy, laborious and costly process. Whereas the needle punched fabric production is a short process and the manufacturing cost of needle punched nonwoven fabric is much lower. A nonwoven blanket is defined as a blanket produced by bonding or interlocking of fibres or both, accomplished by mechanical, chemical, thermal or solvent means or combination thereof. The important parameters, which affect the structure and properties in a needle punch nonwoven blanket, are the web parameters (type of fibre and fabric weight per unit area) and machine parameters (depth of needle penetration and needle punch density). The important requirements for end use performance of blankets are good handle, softness, good abrasion resistance, good thermal insulation in winter and good air permeability in summer. Fabric abrasion resistance increases linearly with the increase in needle punch density, but as the needle punch density is increased the other important properties like thermal resistance and handle are adversely affected. So a fabric with good thermal and handle properties will have poor abrasion resistance and vice-versa. So to design a blanket with good abrasion resistance without spoiling the softness and thermal properties, the machine parameters and web parameters are to be systematically optimized.
Project aims and objectives The objective of the project is to produce a cost effective nonwoven blanket by optimising the machine parameters to produce good thermal, softness and abrasive properties

Designing Nonwoven Fabric for Pulse-jet Filtration Other Partners: Academic

Project start date: 31 March 2005 Project end date: 30 September 2008 Project budget: Rs. 15 lacs Source of support: Ministry of Human Resource Development, Government of India Keywords: Dust particle, Nonwoven, Pulse-jet filtration Primary factors which determine the selection of a fabric for a particular application are state of aerosol medium (thermal and chemical condition, static charge on the particles, abrasive particles, moisture in the gas stream etc.), filtration requirement (particle capturing efficiency, pressure drop and cleaning) and equipment consideration. The particle capturing mechanism by fabric filters based on reverse jet cleaning is well researched. A number of studies reveal the effect of fabric structural parameters on its filtration characteristics. Further a number of attempts have been made to improve filtration efficiency with reduced pressure drop and better cake release performance. However, it is worth mentioning that the above studies becoming rudimentary since pulse jet filter has become an attractive option of particulate collection utilities. Pulse jet cleaning is a technique whereby a short, periodic, high pressure burst of air is fired into the clean side of the fabric. The particles are dislodged and the pressure drop falls to an acceptable level. Pulse jet filtration can meet the stringent particulate emission limits regardless of variation in the operating conditions. The cleaning device is less expensive than other type of mechanism and requires considerable less space. Other merits of pulse jet fabric filters are high collection efficiency, on line cleaning application and outside collection which allows the bag maintenance in a clean and safe environment. The increasing adoption of pulse jet filters for control of process emissions and recovery of utility dusts has stimulated research on many aspects of their operation. Despite their wide applications, the functioning of fabric filters is poorly understood. The operating condition is usually specified by the manufacturer at the time of commission. In practice, however, the filtration process frequently undergoes changes in the operating condition caused by the disturbances due to the variation in the concentration of dirty air, variation in particle size etc. Due to the complex characteristics inherent in the filtration and cleaning process of pulse jet bag houses, the proper understanding of the role of fabric construction on filtration is very important.

The separation of solids from fluids by textile filter media is an essential part of countless industrial process, contributing to purity of product, saving in energy, improvement in process efficiency, recovery of precious materials and general improvements in pollution control. The dust may create environmental pollution problems or other control difficulties caused by their toxicity, flammability and possible risk of explosion. The particles in question may simply require removal and be of no intrinsic value or alternatively may constitute part of a saleable product, for example, sugar or cement. Among several techniques, the most efficient and versatile is the fabric collector, especially when processing very fine particles. Fabric filtration under pulse jet situation becoming very common in industrial bag house filtration. However, there is lack of study on the role of fabric under the said circumstances. It is also important to develop the fabric suitable for pulse-jet filtration. Therefore, we are having the following objectives: . .
.
Understanding the mechanism of filtration under pulse-jet situation. Studing the effect of geometrical parameter of nonwoven fabric on filtration performance. Design and development of suitable nonwoven fabric under pulse-jet situation.
Research deliverables (academic and industrial) Initially the work will be concentrated on studing the impact of structural parameter of nonwoven fabric on its filtration performance in case of cement dust. This will lead to the development of suitable nonwoven fabric under pulse-jet situation in cement industry.

Heat transfer through PPC with different radiant and moisture transport properties is studied. First on material samples, followed by thermal manikin measurements and finally in a select number of conditions, in human wear trials. Data will be used to derive general models of either analytical (WP1, WP4) or conceptual (WP2) nature of heat transfer through PPC in relation to clothing material properties, climate etc. The last stages of the project focus on the effect of protective clothing on energy use. Most protective clothing increases energy use disproportionally more than the weight would suggest. This effects wearers in terms of work capacity, time to exhaustion and e.g. for firefighters in the time available before the compressed air runs out.
Project aims and objectives .
To improve the representation of clothing in ISO and EN heat and cold stress assessment standards.
.
To get a better understanding of the interaction of moisture and heat transfer. To understand which factors influence the energy requirement increase caused by clothing.

Project start date: 30 September 2006 Project end date: 30 August 2007 Project budget: £36732 Source of support: MIRIAD / Department (internal funding) Keywords: Knitted garments Anthropometrical Knitted garments and the relating technologies have advanced immensely during the last decade especially in the areas of fully fashioning (integral shaping) and complete garment production. Various new techniques have become available in modern knitting machinery including microprocessor-controlled mechatronic systems for needle selection and fabric take down systems, as well as automated loop transferring. These technologies have enabled knitwear to be shaped three-dimensionally as not previously achievable through the sophisticated CAD software that generates pattern and control during knitting. Despite this advancement in programming software and electronic needle selection, garment development is still heavily reliant on the skill of the operator or designer to develop new shapes and manipulate this advanced technology into innovative knitwear. This advance in technology has opened up a large knowledge gap with regards to fit and styling within knitwear, and many questions have arisen; Do we really understand the relationship between anthropometrical data and knitwear sizing, styling and fit and do we utilise the knowledge effectively to enable predictions of fit to occur? In previous research it was found that many new knitwear developments are based on empirical knowledge utilising the trial and error approach to develop styles with good fit which conform to the human figure and the theoretical application is very much lacking. This suggests that there is a void caused by the lacking of theoretical data and a knowledge gap between the relationship of anthropometrics and knitwear development. It is vital to assist the industry by providing a sound theoretical understand in order to minimise time wasted utilising the trial and error approach which appears to be considered the current industry norm. In addition to the strong technical justification for the project investigation regarding the use of anthropometrical data in knitwear development, there is evidence that during resent years knitwear has become a key fashion item, a greater percentage of a clothing range in retail outlets are knitwear based. It has also been acknowledged that the individual knitwear manufacturers are placing much more emphasis on the development of new shapes that conform to the human form. However, there is an uncertainty regarding how much of this is derived from empirical development and the quantity that has a sound theoretical framework grounded in anthropometrical studies.
Project aims and objectives .
A thorough literature search to determine the key players; and establish knowledge gaps in relation to the use of anthropometrical data in knitwear sizing.
.
Intense market research collating knitwear sizing and anthropometrical data.
.
Through visits, interviews will be conducted with five key manufacturers to evaluate the current industry standards in relation to knitwear sizing and the usage of anthropometrical data.

Using laboratory based procedures analysis will occur by scientific evaluation into the current grading procedures in knitted garments, to determine the current industry standards. Devise a database of anthropometrical information related to knitwear styles and sizing.
Research deliverables (academic and industrial) It is thus proposed to conduct investigation through a research project into the use and understanding of anthropometrical data in knitted garments. This will occur in the form of a study into the development and production of current knitted goods by primary research involving extensive practical observation by scientific means. This will result in the analysis of four basic stylelines in a variety of sizing codes. In addition it is proposed that five UK knitwear manufacturers will contribute information regarding their internal knowledge of the use of anthropometrical data within their current knitwear developments. The second part of the study will involve the collating of information gained from the scientific observation and the primary research from the knitwear manufacturers. A Research Assistant funded entirely by the project will conduct the extensive laboratory observational research to enable the research outputs to be achieved. Publications
This research is grounded in previous postgraduate work and will expand on the department’s current research portfolio within anthropometrics and knitwear. The output will be in two phases: Phase 1 . .
Publication to outline the initial findings of the background study. A conference presentation based on the findings of the primary investigation.
Phase 2 . A framework for further research in the form of scholarly activity. .
Development of a short course to relate the findings directly back to the industry.

It is subdivided into three thematically connected parts, which included: a) basic investigations of the mechanics of woven fabrics as complex textile structures, b) modellling the behaviour of complex textile structures, and c) characterising the parameters of thermal-physiological comfort. The first part of activities is based on the knowledge of mechanical laws of fabric behaviour at low loads and is aimed at defining the quality properties of garment form appearance. Fabric behaviour from the point of view of mechanics in processing from a plane into a 3D garment shape is determined, the importance of individual parameters of mechanical and physical properties is evaluated and a knowledge basis used to predict garment appearance is constructed. Based on the laws defined and appearance quality factors, we have developed the “Intelligent system for predicting garment appearance quality”, called InSyPrGAQ, or InSiNaKVO by Slovenian acronym. InSiNaKVO system is designed using the method of machine learning and represents an innovation – the first effective tool for objective evaluation and prediction of the degree of garment appearance quality. The system is based on the ratio among the parameters of mechanical and physical properties and the degree of garment appearance quality, and it is aimed at predicting the degree of garment appearance quality on the basis of the parameters of mechanical and physical properties of the fabrics built into the garment evaluated. It offers: . objective evaluation of the garment appearance quality degree; .
.
predicting five key factors of garment appearance quality degree: garment drape or fall, 3D form, fitting, the quality of the seams and garment appearance quality as a whole; planning the target degree of garment appearance quality;
.
predicting garment appearance quality degree for particular fabrics in a direct manufacturing process; and
.
planning the parameters of fabric mechanical and physical properties for the target degree of garment appearance quality.
The second part of activities involving modelling complex textile structures deals with continuation of the investigations of complex fabric deformations, with the accent on studying rheological models. Fabric relaxation is here studies from the point of view of mechanical multi-component models, which are able to describe in a satisfactory manner deformation and relaxation processes in fabrics, this being the starting point for numerical modelling of fabric behaviour, fabrics being complex textile structures. The third part of investigations deals with the characterisation of thermalphysiological comfort parameters. Comprehensive research of heat transfer and

flow, as well as thermoregulation, together with the investigations of textile material properties have been performed. Investigations of matter properties and specific requirements imposed on textile materials of a particular target group have been performed for convetional and functional fabrics, as well as for the combinations, aimed at planning garment systems of business suits. The research is organised at three levels. The first includes investigations of thermal-physiological parameters on so called sweating cylinder for the selected fabrics and combinations of the planned garment systems (This research was performed in SmartWearLab of the Tampere University of Technology). The sweating cylinder simulates the functioning of human body allowing heat flow through the textiles or combination of textiles tested, as well as water vapour flow (the process of sweating), employing numerous sweat glands on the cylinder surface, which provide, i.e. transport particular amount of water to the surface. The purpose of the experiment is to establish the best combinastion of textile fabrics, such that could grant the required thermalphysiological comfort to the wearer. The second part of the research is aimed at evaluating and testing the business garment system by using a sweating thermal manikin, that simulates heat and moisture production in a similar way to the human body and measures the influence of garment system on heat exchange in different environmental and sweating conditions. The third level of the investigations includes evaluating and testing garment systems, empoloying testing persons under artificially designed weather conditions in a computer-controlled chamber. The results to be obtained will influence the characterisation of the thermal-physiological comfort parameters. It will be used to design a numeric simulation of heat exchange between the body and the garment, e.g. other textile products and the environment.
Project aims and objectives The main objectives of this project are as follows: .
To define the relationships between fabric mechanical properties and quality of a produced garment.
.
To develop a model for prediction of garment appearance quality.
.
To set-up a model of fabric behaviour as shell. To systematically investigate the parameters of thermophysiological comfort.
. .
To develop a numerical simulation of heat exchange between the human body and garment system or other textiles products and environment.
Research deliverables (academic and industrial) The research programme is systematically designed so as to result in the knowledge that could be used in establishing and engineering concept of garment and/or other textile product planning particularly the so called “knowledge-based products”. The results have partially been made applicable through the development of the InSiNaKVO system, the main characteristics of which are as follows: (a) knowledgebased designing and predicting garment appearance quality degree, using known fabric mechanical and physical properties (b) planning fabric mechanical and physical
properties so as to get the target garment quality level, and (c) tools to simulate the degree of garment quality. Publications Gersˇak, J.

After the relaxation because of a typical viscoelastic properties one part of deformation disappears immediately (elastic deformation), the other part disappears with time (elastic deformation retained) and the remaining part stays behind as a durable and irreversible deformation. The aim of the research project is to study the elastic behaviour of fabrics with elastane yarns taking into account the elastic potential, elastic deformations and relaxation ability based on the study of fabric mechanics, with the purpose to gain new cognition about the relationship between elastic deformations and relaxation phenomena in such fabric type. The main part of the research is focused on the study of elastic deformations and relaxation phenomena in fabrics with elastane yarns, where the influence of the parameters of tensional-elastic properties of such fabrics on elastic deformations and relaxation level will be investigated taking into account loading intensity. Special attention is given to the study of time dependence of relaxation phenomena in fabrics with elastane yarns and special relaxation conditions of such fabrics during spreading and laying into fabric layers, i.e., influence of the length, surface friction between fabric layers and number of layers. For this purpose the stress relaxation during witholding under constant deformations and the relaxation of fabrics after manually unwinding and spreading were studied. The relaxation of fabrics represents as elastic recovery and response of fabric as the result of loading during winding and spreading to form by lay. Based on given results of relaxation of fabric as the consequence of winding process was found that with higher percentage of containing elastane in the yarn grows the degree of deformation. The investigation results show also an important influence of the elastane yarn construction on relaxation phenomena in fabrics.
Project aims and objectives The main objectives od this research are as follows: .
To find the correlation between the elastic deformation and relaxation level in fabrics with elastane yarns.
.
To set up the model for predicting the relaxation of fabrics taking into account the parameters of fabric’s tensional-elastic properties, parameters of the spreading process, as well as the length and number of fabric layers.

generator (TexGen). Textile modelling provides a launchpad for downstream simulation of processing, damage mechanics and environmental performance. The functionality of our existing TexGen software will be extended and coupled to materials models for simulation of each of the above aspects of physical behaviour. Simulation of each of the physical processes will be enhanced by a common, interchangeable geometric definition of the textile structure within the rigid composite. This will enable a rapid understanding of fabric architecture effects to be built and the approach has excellent potential for application to other physical problems which relate to rigid and flexible composites or technical textiles. The platform grant application seeks continuity of support for key workers during the period of this development. Further details are available at: www.textiles.nottingham.ac.uk

All citizens are permanently protected by flexible structures with barrier noise and thermal insulation, shield against electrostatic or electromagnetic phenomena, filtration of dust or insects.. The application of flexible structure is very large thanks to their easy adapting properties and shape. Nevertheless, they will maximise the level of safety in building, transportation and to ensure the well-being of European citizens, The flexible structures, generally based on paper, leather or textile are usually treated to serve only one barrier effect.Ires a whole re-design of flexible structure functions that is the main purpose of FLEXIFUNBAR. For instance to prevent from all external aggressions in hazardous atmosphere, flexible structure must provide at least barrier effects. The ultimate goal of flexifunbar initiative is to develop innovative generation of hybrid multi barrier-effects materials, based on multi layer complex structures and funcionnalisation of micro and nanostructures.The development of such materials covers a large range of applications: . Transportation: filter, thermal and acoustic insulation panel, pollutant detectors. .
Home and building: wall covering, home furniture, carbon monoxide detectors, antibacterial mattress, electromagnetic insulation panels.
.
Health: protection of people against insects, protective clothing for military and defense, hygiene mask, operation area.
Project aims and objectives The innovation of Flexifunbar lies in the principle of associating in one same material several functionalities: Heat insulation, acoustic insulation, shielding against electromagnetic waves, anti odours, anti bacterial, flame retardancy. . . The objective of Flexifunbar is to develop and promote multi-functional flexible structure for use in many multisectorial industrial applications in the health field as well as in the building construction and transportation industrie..

Instrumented clothes will provide remote monitoring of vitals signs, diagnostics to improve early illness detection and metabolic disorder and benefits to the reduction on medical social costs to the citizen. Ambulatory healthcare, isolated people, convalescent people and patients with chronic diseases are addressed. To date, developments in that field are mainly focused on physiological measurements (body temperature, electro-cardiogram, electromyogram, breath rhythm, etc.) with first applications targeting sport monitoring and prevention of cardiovascular risk. Biochemical measurements on body fluids will be needed to tackle very important health and safety issues.
Project aims and objectives The BIOTEX project aims at developing dedicated biochemical-sensing techniques compatible with integration into textile. This goal represents a complete breakthrough, which allows for the first time the monitoring of body fluids via sensors distributed on a textile substrate and performing biochemical measurements. BIOTEX is addressing the sensing part and its electrical or optical connection to a signal processor. The approach aims at developing sensing patches, adapted to different targeted body fluids and biological species to be monitored, where the textile itself is the sensor. The extension to whole garment and the integration with physiological monitors is part of the roadmap of the consortium. Textiles for applications in health monitoring are becoming a major theme for the citizen’s healthcare and safety since they allow:
.
simultaneously comfort and monitoring (for safety and/or health);
.
non-invasive measurements, no laboratory sampling; continuous monitoring during daily activity of the person;
. .
Research register
possible multi-parameter analysis and monitoring; and
distributed sensing thanks to access to 90 per cent of the body surface if integrated on clothing. Societal issues such as ambulatory healthcare, isolated elderly or disabled patient’s care may be tackled by these techniques. Moreover, non-invasive and continuous monitoring of people in a critical state is more and more needed e.g. in emergency services, for heavily burnt patients and safety, e.g. exposed personnel like fire-fighters. At the present stage, health-monitoring systems using electronic textiles are mainly targeting applications based upon physiological parameter measurements, such as body movements or electro-cardiogram. To open a dramatically wider field of applications, biochemical measurements on body fluids (blood, sweat, urine) will be needed. At the present time, biochemical analysis systems compatible with integration into clothing are unfortunately lacking. This is a major drawback for instance in the case of sweat analysis which is potentially very rich in health related information. However, such analysis is hardly performed today because of the difficulty to sample sweat in sufficient quantity. Only a real textile sensor embedded in a garment through textile techniques will allow direct collection of sweat and a large body surface; moreover lower fabrication costs are expected. For blood analysis, the main interest will be to avoid invasive sampling and to allow continuous analysis. BIOTEX aims at the development of technologies to fulfil these needs. .

Project start date: December 2003 Project end date: September 2007 Project budget: University of Pisa: e976,168 Source of support: European Commission Cardio-vascular diseases (CVD) are the leading cause of death in the west. In Europe over 20 per cent of all citizens suffer from a chronic CVD and 45 per cent of all deaths are due to CVD. Europe spends annually hundreds billion Euros on CVD. With the upcoming aging population, it is a challenge for Europe to deliver its citizens healthcare at affordable costs. It is commonly accepted, that a healthy and preventive lifestyle as well as early diagnosis could systematically fight the origin of CVD and save millions of live-years. The MyHeart mission is to empower citizen to fight cardio-vascular diseases by preventive lifestyle and early diagnosis. The starting point is to gain knowledge on a citizen’s actual health status. To gain this info continuous monitoring of vital signs is mandatory. The approach is therefore to integrate system solutions into functional clothes with integrated textile sensors. The combination of functional clothes and integrated electronics and process them on-body, we define as intelligent biomedical clothes. The processing consists of making diagnoses, detecting trends and react on it. Together with feedback devices, able to
interact with the user as well as with professional services, the MyHeart system is formed. This system is suitable for supporting citizens to fight major CVD risk factors and help to avoid heart attack, other acute events by personalized guidelines and giving feedback. It provides the necessary motivation the new life styles. MyHeart will demonstrate technical solutions. The outcome will open up a l new mass market for the European industry and it will help prevent the development of CVD, meanwhile reduce the overall EU healthcare costs. The consortium consists of 33 partners from 11 countries. It is a research effort of industrial, research institutes, academics and medical hospitals, covering the whole value chain from textile research, via fashion and electronic design, towards medical and home-based applications.
Project aims and objectives The MyHeart approach for solving the key challenges is based on the development of intelligent biomedical clothes for preventive care application tailored to specific user groups. In order to focus on the user motivation and the individual benefit, we define the main objectives along 5 different application areas. These application areas reflect the main risks for developing a CVD and address the user need for early diagnose to limit the severity of an acute event.

ProeTEX will develop integrated smart wearables for emergency disaster intervention personnel, improving their safety, coordination and efficiency and for injured civilians, optimising their survival management. This core application area, which is of significant societal importance in itself, will drive a wide range of key technology developments, building on current and past EU and national projects and the commercial activities of partners, to create micro-nano-engineering smart textile systems – integrated systems (fabrics, wearable garments) using specifically fibrebased micronano technologies. These are capable of being combined into diverse products addressing this core application area but also a wide range of other markets from extreme sports, through healthcare to transportation maintenance and building workers. The industrial partners can address these markets. Fiber systems can integrate sensors, actuators, conductors, power management, and the emergency disaster personnel smart garment will, within a wireless ambient planning and managing environment, progressively enhance and integrate fiber systems for: .
continuous monitoring of life signs (biopotentials, breathing movement, cardiac sounds);
.
continuous monitoring biosensors (sweat, dehydration, electrolytes, stress indicators);
.

The main objective of this project is to obtain a breakthrough for SMEs on the development and use of engineering thermoplastic and thermosetting materials mainly from natural resources, like lignin from the paper industry and from the High Presure Hydrothermolyses (HPH) process, other biopolymers (here referred as biopolymers: e.g. Polylactide, Polyhydroxy-butyrate, Starch), furan resins, woven and non-woven cellulose fibres and fibre mats to final model products. The technical work programme will comprise the complete technical path from the input of natural raw materials (fibres, polymers and natural additives) to the output of final top quality engineering composite materials and model products (e.g. housings for electronic equipment, car front end interiors, glass frames etc.) with an environmentally friendly life cycle. In parallel, there are activities concerning standardisation of characterisation and test procedures and quality control. Demonstration by the model products supporting the dissemination and the exploitation of results will exhibit the benefits of the materials and deliver a first input to material databases. An integrated concept of sustained skill and education of staff and students will provide routines and access to the material data.

Different surface modifications, pretreatment and finishing of textile, especially cotton and polyester, will be performed according to European Technology Platform for the future of textile and clothing. For such purpose advance processes like mercerization, cationization, alkali, EDTA, other compounds and enzymes for surface hydrolysis of PET fabric, optical bleaching, implementation of nano antimicrobial active silver ions and mineral delivery mechanism, zeolite and others will be performed. Aminofunctional and other compounds will be added to azalides for the synergistic high antimicrobial effects. In cotton pretreatment enzymatic scouring will be applied using enzymes pectinase and the newest cutinase, for removal of pectins and bioplymers from cotton impurities with lipophylic character, instead of ecologically unfavorable alkali scouring. The goal of the project is synergistic effects of some compounds on modified textile surface. Interface phenomena of the new textile materials produced from electroconductive, low electro resistance fibers will be investigated for the purpose of static electricity and electromagnetic protection and for its implementation as sensors or other electronic devices in intelligent textiles. Traditional protection and aesthetic role of textile will be spread in active textile multifunctionality. Project will deal with elektrokinetic phenomena (zeta potential, isoelectric point, IEP, point of zero charge, PZC, surface electrical charge, surface free energy), hydrophility and hydrophobilicity, whiteness, fluorescence and phosphorescence, friction, fabric cover factor, elasticity, air and water vapor permeability of textile materials and their protection on UV radiation, microbes and fungi, coldness, heat and flame, static electricity and electromagnetic field.
Project aims and objectives Project will continue researching on assignments from previous project (0117012). Purpose of these investigations is based on lightening of interface phenomena on textile which effect directly to its adsorption and interaction intensity between textile fibers and chemical compounds. Almost all possibilities in modification during manufacturing high performance synthetic fibers are used, therefore nowadays attention and research is on textile surface modification. Procedures and compounds for that modification varies, as their effect varies, but the purpose and aim are directed to synergism of two or more components for accomplishing hydrophob or hydrophil textile, textile highly resistant to atmospheric condition, bacteria, microbe and fungi, UV radiation and open flame. Furthermore important aim of the project is cotton high level of purity by unconventional agents and material pretreatment procedures for mercerization and cationization. Pectinase in previous project investigation showed good elimination of pectine from primary cotton layer, but hydrophility was not so high like alkali scoured cotton. Chemical composition of cotton cuticula has lypophilic polymers, biopolyesters, which can be degraded by cutinase, new enzymes for degradation of waxes for better hydrophility. Cotton cationization during mercerization is the most important innovation of previous project and the patent for it was asked. Electronegative cotton surface charge, of which anionic substances adsorption depends, is lower after cationization in harsh mercerization conditions. The aim of this project is antibacterial, UV and flame protection by nanoparticle implementation (Ag) using mineral delivery compound (zeolite and others) as well. Electroconductive fibers implementation in yarns
of textile materials should result in static electricity removal, and hopefully other effects. The aim of polyester surface modification, optical bleaching, other compounds treatments is well-known aesthetic, as well as high UV protection, high material elasticity as a result of changes in fiber microstructure. Interface phenomena research on wide range possible fabric knitted and woven construction will givethe solution of problems of fabric construction influence to high effect in this project.

73 Research deliverables Interface phenomena of textile materials surface in wet medium results in textile electric surface charge cognition and surface free energy as well on which adsorption depends. Important application of this project results is in ecological enzymatic scouring with pectinases.Enzymatic scouring with new enzymes, cutinase, will remove biopolyester cuticula and improve cotton hydrophility, and therefore replace harsh conventional alkali scouring entirely. Important application will have, patent requested cotton cationization during mercerization. By this pretreatment electropositive cotton is achieved, with great anion adsorption on its surface in all textile finishing processes. These anions enclose all low and high molecular compounds for textile finishing and all pricondensates. Implementation of nanoparticles (Ag and others) is predicted during mercerization and cationization processes, therefore it is important to emphasize rational component of these procedures which gives cotton multifunctionality in all textile usage. The next important application is antibacterial textile accomplished with azalide treatment especially in synergism with aminofunctional and other compounds and systems. It is well-known that fluorescence of optically bleached increases whitening of textiles. Optical brighteners and other compounds researching will be of great importance in UV protection with textile material. Heavy metals are toxic and their research is of great importance in human health protection. Furthermore, in nowadays growing demands on life safety from external influences especially UV radiation, research of differently structured textile material interface phenomena will find application in textile for summer clothing.

Department of Analytical and Food Chemistry, University of Vienna, Austria Project start date: 1 January 2006 Project end date: 31 December 2007 ¨ Source of support: Osterreichischer Austauschdienst (O¨AD, Austria) and Ministry of Science, Education and Sports, Republic of Croatia Keywords: Textiles, Heavy metals, Human health Many textiles may contain various chemicals that represent a health hazard to consumers and an environment when discharged into wastewater from households, laundries or textile industries. The risk involved due to chemical pollutants in respect to health hazard depends on the toxicity of certain chemicals, their quantity present in the products and the duration of exposure to them. One important type of substances mentioned above is heavy metals. Systems in which toxic metal elements can induce impairment and dysfunction include the blood and cardiovascular system, eliminative pathways (colon, liver, kidneys, skin), endocrine (hormonal) pathways, energy production pathways, enzymatic, gastrointestinal, immune, nervous (central and peripheral), reproductive and urinary system. This is the reason why the heavy metals which are present in the textile material represent a source of pollution which must be controlled to protect both the environment and human health.The most important standards in Europe for evaluation of the textiles ¨ ko Tex Standard and M. S. T. (Markenzeichen schadstoffgepru¨fter Textilien). are O According to its requirements, the textiles are controlled for extractable harmful heavy metals (As, Pb, Cd, Cr, Co, Cu, Ni, and Hg).
Project aims and objectives The objective of this project was the investigation of the impact of heavy metals from ¨ ko Tex standard. textiles on human health which will be examined according to the O This means a study of the extractable harmful heavy metals such as As, Pb, Cd, Cr, Co, Cu, Ni, and Hg from Croatian and Austrian textile products made of cotton, flax, wool, silk, viscose, and other similar materials which are manufactured and used daily. Since a majority of problems arise in the field of heavy metal complex dyes which could be extracted from the fabrics by perspiration or saliva solutions, the primary target of
interest was the determination of extracted heavy metals from different textile materials according to the O¨ko Tex standard. The quantity of extractable harmful metals in the textiles should not exceed the given limits. Leaching of heavy metals from textiles was carried out in saliva and perspiration solution (artificial acidic sweat solution, according to the ISO 105 – E04) using ultrasonic as well as microwave extraction methods. The metals will be separated simultaneously, identified and quantified by a rapid screening method (thin layer chromatography and video densitometry). UV/VIS spectrometry was applied as an additional comparable method for determination of particular extractable heavy metals. Main advantages of thin layer chromatography are the low costs, its ease of operation and rapidity.
Research deliverables The results obtained in Croatia with UV/VIS and TLC were compared to those achieved in Austria by graphite furnace - atomic absorption spectrometry (GF-AAS) and inductively coupled plasma – optical emission spectrometry (ICP-OES). The metal concentrations was be determined by GF-AAS and ICP-OES after preparation by microwave digestion oven in nitric acid. GF-AAS and ICP-OES are widely used analytical methods for the determination of trace and ultratrace elements in all kinds of samples. Whereas ICP-OES is simultaneous multielement method with high sample throughput, GF-AAS is a single element method requiring smaller sample amounts and enabling lower limits of detection especially for the toxic metals As, Cd and Pb.

Sitting furniture should enable the worker to take an optimal bodily sitting posture, ensuring active and dynamic sitting. A long-lasting and non-ergonomic bodily posture in this position causes uncomfortable sitting. Defining optimal working postures and strains makes a contribution to the reduction of necessary energy and facilitates working and circulation functions. The total work space should be designed in compliance with all criteria of the working posture and technical requirements. It is necessary to know the worker well, his working capabilities, work place and work methods to ensure an optimal working environment. Furniture dimensions and workplace, surrounding the furniture, regarding its optimal utilization, should be harmonized with the worker’s anthropometric sizes. Research methods are experimental, theoretical and numerical. Functional dependences of the worker-furniture-environment system will be investigated, based on ergonomic postulates in order to find optimal conditions between work humanization and productivity. Investigations are determined by measuring and recording typical working postures as well as conditions of excessive workload. Using digitally scanned 3D anthropometric characteristics of the human body, a digital 3D biomechanical model is obtained, taking account of the appropriate kinematicdynamic motion rules and the construction of the inner skeleton. 3D program applications with advanced automated defined anthropometric and ergonomic features of biomechanical models and digital figures will be recorded. A 3D visualization of the workplace by using a computer-based 3D model of furniture and computer-based character animations of workers will be performed. By using computer 3D program solutions, the prototype is substituted by 3D models on which all necessary designs and changes in real time have been carried out interactively. Computer visualization will be used to perform a biomechanical analysis of movements based on the real correlation within the space of the interaction of workers and belonging working environment on the obtained 3D models of workers and workspace. It is necessary to analyze the workspace and time studies of motion accurately. The 3D virtual model will enable a detailed biomechanical analysis of motion, speed and acceleration and more designer’s solutions of furniture with biomechanical and ergonomic parameters. Detrimental impact of too a high noise on workers as well as efficient procedures of noise reduction will be investigated. Special attention will be focused on detrimental action of microclimatic conditions regarding technological requirements of the industry. The optimization of work energy during the performance of the work by the worker will be performed to lessen fatigue and to remove excessive workload and to reduce sick-leaves. The performance of these investigations will result in ergonomic technical-economic design of the interactive work-furniture-environment system which is of great importance for the development of the Republic of Croatia and elsewhere in the world.
Project aims and objectives The purpose of these investigations is to achieve the reduction of work energy when workers work in sitting position and to enable the reduction of fatigue and falling ill. When performing work, a better economic performance with a lower energy consumption and operator’s fatigue should be obtained. In testing the level of detrimental sound effects their efficacious reduction could be achieved. The action of noise and vibrations could be prevented by investigating efficient noise and vibration dampers, damping the transfer of vibrations on workers by using pads and personal protective equipment. The aim of these investigations is to optimize work movements in sitting position with less operator’s fatige and reduction of sick-leaves in the industry. Thereby, working conditions and environment as well as safety in technological processes are to be especially stressed. They should be used to improve economic characteristics substantially. Special purposes of the investigation are the optimization of working postures and the confirmation of the knowledge about defining new criteria for the right ergonomic design of working pieces of furniture.
Research deliverables The application of investigations means work simplification, investigation and determination of manufacture time from the point of view of ergonomic starting points. When performing work, a better economic effect is to be achieved with a less energy consumption and operator’s fatigue. Based on the investigated causes of the increase of sound pressure level of machines, it is necessary to find out qualitative solutions to reduce the level into permitted and tolerable limits. To obtain satisfactory microclimatic conditions, work spaces, machinery and air-conditioning instruments with better economic and other characteristics will be defined, whereby current energy consumption will be reduced. Furniture dimensions are determined by computer based visualization of virtual 3D character in interaction with digitized and really designed furniture and environment. Virtual simulation offers the opportunity to create optimal constructive solutions of furniture which enables active and dynamic sitting. It is a relaxation bodily posture that is thereby obtained when sitting. Ergonomic, anthropometric, functional and technical requirements of workers are thereby satisfied. A 3D simulation model of comfortable and safe bodily posture in sitting position is created, together with all biomechanical characteristics, and interactive effects with existing and new materials used for making sitting furniture are attained. Thereby, design and construction of sitting furniture is supplemented, which, because of its designer and constructive solutions and design observance, reduces the possibilities of low-quality designs and problems of body illness and causing inability to work.

Anthropometric Measurements and Adaptation of Garment Size System Other Partners: Academic
Industrial
Project start date: 1 January 2007 Project end date: 31 December 2011 Source of support: Ministry of Science, Education and Sports, Republic of Croatia Keywords: Anthropometric Measurements, Garment Size System Systematic anthropometric surveys have been conducted since 1901 with the aim of developing and improving systems for clothing and footwear sizes. The measurement results show how a national population changes over a period of several decades in physical build and size due to a series of factors (food habits, sports development, genetic predispositions, population migrations, climatic conditions etc.). Based on the results of anthropometric measurements in the Republic of Croatia (2004/05) on the sample of 30,866 test persons aged between 1 and 82 a statistical analysis of body measurements was performed, a database including 5 basic studies of sex and age as well as a new standard for clothing and footwear was built. These results enable a significant and stimulating continuation of scientific research and a comparison
to other national standards and their contributions to the creation of systems for clothing and footwear sizes. Elements common for national standards of garment sizing by an exact approach will be investigated and analyzed, in particular because the presumptions of national systems and starting elements respectively are not universally founded like intersize intervals which differ in sizes since the conformity of individual starting places is missing. Data will be provided for a common base with methods of body measuring and size designation of clothes according to the recommendations of the Technical Committee TC133 within ISO and EN standards as well as the design and development of a sophisticated computer system (DOV-KO) for unifying all body measurements and basic garment construction based on one or all other sizes. Within the scope of this project and based on experience, a very important cycle of anthropometric measurements of the sporting population in football, water polo, rowing, basketball and handball will be performed. 4,000 test persons from Zagreb, Osijek, Rijeka, Split and Dubrovnik will be measured, whereby specific body differences and deformations of muscles caused by longstanding training will be analyzed. A comparative analysis of the representative sample of the anthropometric measurements of sportsmen and other population as well as the investigation of other trends of body measurements will be performed. This will enable an exceptional insight into the anthropometric dimensions which reflect body shape, proportionality, composition and elements of success in sports respectively. Stadiometar or a new measuring instrument for continuous measuring body height, foot length and width will be designed too.
Project aims and objectives Problems of garment sizing and fit affect the market globally, and a consequence of bad predictions of the quantity of necessary stocks for manufacturers and dealers poses a risk of high costs. In the case of domestic manufacturers samples may be additionally divided. Particular solutions may be considered more efficiently by interpreting the data from the anthropometric database connecting five studies according to sex and age and the system of sizing. Therefore, using the results of the anthropometric measurements taken and the basic projection of the new standard for clothing and footwear, one of the directives of the project is to investigate other national standards of Europe and the world and to create size intervals and a new Croatian standard. The study of body differences and specific deformities of the body muscles during the longstanding practice of athletes such as leg circumference, chest circumference, torso, shoulder width, arm and leg length, body height, palm length is an additional aim of this project which will show the body elements affecting success level in sport. Besides a greater adaptation of clothing and footwear to the home market, it would be advisable to ensure the continuity of investigating the national size standard by creating a sustainable Croatian system of clothing and footwear sizes in conformity with anthropometric surveys that are conducted periodically and systematically in developed countries in which a change in the morphology of the human body occurred over the last decades. By way of proof, systematic anthropometric measurements and sizing in

France showed a tendency of average height growth. In Great Britain in female population a growth of bust circumference was recognized, whereas in USA studies point to the tendency of an increase in obesity (besides an aesthetic also a health problem). The interest of the scientific and professional public, manufacturers, tradespeople and consumers in sizing will continue to grow, since a faster change in established body proportions may be expected thanks to changes in living and food habits of the population, an unavoidable mingling of ethnic groups, increase in the number of older consumers of clothing and footwear which will be doubled in the next two decades etc. Thus, it is additionally stressed how much it essential at the moment to ensure a valid starting point or a Croatian standard to pursue next movements of body dimensions in order to avoid a discrepancy and imposition of the specificities of domicile consumers to home and foreign manufacturers.
Research deliverables Anthropometry is the study of the measurement of the human body, but Pheasant has expanded it as “applied anthropometry” including quantitative data of size, forms and other physical characteristics of people that can be used in garment design. Since the form of the human body changed through time, the problem of ageing proved to make a contribution to perceived changes in body shape and size more than any other individual factor, such as for example improved nutrition and prolonged life, in particular the knowledge that the number of older consumers will be doubled by 2003. Therefore, the systems of sizing shall be updated periodically to ensure a correct fit of ready-made clothing. On the other hand, the home industry of clothing, fashion wear and footwear disposes of modest and aged data based on the out-of-date anthropometric measurements from 1962. It was therefore necessary to conduct a new cycle of anthropometric measurements and to use the obtained results. World fashion industry shows a special interest in measuring anthropometric characteristics of the population so that it gathers such data permanently, motivated by the wish for designing articles of clothing for all population groups, including the persons with pronounced specificities (higher stature, higher body weight etc.). The use of investigations will contribute to creating a new and modern Croatian standard for clothing and footwear harmonized with ISO and EN standards. Besides the clothing and footwear industry, pediatricians, specialists of occupational and sports medicine, experts in wood processing industry, automotive industry, in the army and police will benefit from the investigation results. Teachers and students in undergraduate and graduate studies as well as teachers and pupils at technical schools will benefit from the development results of the computer system based on the selection of garment sizes. By using the investigations of the sporting population, one can get an insight into tendencies of diversities of body measurements and changes in muscles as a result of longstanding practice. Various specialists of sports medicine, orthopedists, garment and footwear designers will benefit form the results of this investigation because based on previous experience it is evident that mass customization is necessary for athletes. Knowing dimensional characteristics, this method would be considerably promoted and improved.

(UV protection, antibacterial protection, micro capsules of multi-functional performance), applying nano-technology in the dyeing processes with the aim of preventing water contamination, development of new methods as well as purifying dyed wastewaters contribute to sustainable development. Both input and output parameters of water will be controlled throughout the entire dyeing process: amount of residual dye in dyebath using Lamber-Beer absorption model; X, Y, Z standard spectral characteristics of colour defined by specific absorption coefficient SAC and water quality defined by BOD5, COD, TOC, AOX, electrical conductivity and other defining values. System of control comprising advance models of control such as fuzzy logic (model based on rules) and model based on physical and chemical processes will be developed and applied. Capital area of research will involve models of dyeing processes, colour control and its correlation to dye as well as the interactive system of dye control. Models should describe and predict kinetics, reactivity, affinity, exhaustion, fixation and interaction of solutions containing various dyestuffs. Prediction of output process result as well as definition of both physical and chemical parameters crucial for controlling the process will be conducted based on afore-mentioned models. These models encompass kinetic models (according to Nernst and Langmuir) modified for interactions between dyestuff on fibre and in the solution. Interdisciplinarity of dye within the system of sustainable development is based on spectral characteristics of colour as the fundament model dependent of the employment conditions. Instrumental measurement of colour is involved in all industrial production processes: textile technology, design, graphic industry and elsewhere which enables implementing control and colour harmonization. Application of evolutionary algorithms for modeling computer aided design of textiles based on principals of examinee’s subjective evaluation. Methods of descriptive statistics as well as methods of statistic reasoning will be applied within the frame of statistic analysis. Scientific affirmation of research results will be computer simulation as well as in vivo confirmation.
Project aims and objectives Contribution to sustainable development relies on unlimited support of basic, developing and employable research. Aim of the project is to contribute to humane ecology (regarding UV, antibacterial and other protective properties), through use of multifunctional dyes and selection of appropriate waste water discoloration and purifying methods, all in order of obtaining biological quality of water (free of toxic, aromatic components which may form in the process of dye degradation). Cognition of structure and use of thermo sensible nano sized dyes will enable their use on fibres for special purposes. Advance dyeing technologies, with the overview on pretreatment of textile substrates (enzymatic, plasmatic and other) in order of preserving environment and saving energy, will be applied. Base of the project is application of dyeing process control, including advance models of control; fuzzy logic and model based on physico-chemical processes. Colour used as constant value will be applied for formation of fuzzy logic model, used for complex colour designing, automatic dye selection, direct transfer of colour coordinates data into the dyeing recipe setup system, advance recipe correction, as well as control and colour matching. Project research will enable use of new instrumental methods and development of researcher’s creativity, while graduate students and
potential PhD students will be given a chance to get acquainted with scientific methodology, development of experimental skills and writing scientific papers.

Source of support: Ministy of Science, Education and Sports, Republic of Croatia Keywords: Multifunctional eco-friendly textile finishing, Polycarboxylic acids, Protective functionalities, Chemical modification of cellulose, Microvawe treatment of cellulose materials
One of the requests of European Union for higher competiteveness of european market is rebuilding and reconstruction of traditional industrial sectors, especialy textile and wood industry. According to the strategical goals of the Republic of Croatia the project emphasizes the use of highly sofisticated production processes and treatments of cellulose materials i.e. obtaining additional and improved characteristics of wooden and paper matherials which can be acchieved by using high-tech processes and by introduction of nano- micro- and bio-technologies. One of the alternative methods for replaciong the conventional reactants containing formaldehyde which were used in textile and wood treatments so far, would be the modification with eco-friendly agents such as polycarboxylic acids. Efficiency of these treatments will be determined quantitatively by ester crosslinking analytical methods or by means of isocratic HPLC and spectrophotometric FTIR method. Standard methods of textile, wood and paper material testing would be used for examining their protective performance and resistance to weathering conditions. Part of the proposed project will be development of optional multifunctional treatment that would provide better protection of cellulose materials against microorganisms, UV, electromagnetic rays, flame, oil or water. Therefore a particular attention will be payed to development and application of the agents which will not only improve the characteristics of textile matherials but also give it permanent freshness and provide additional care and protection i.e. medical characteristics. Optimisation of alternative processing and methods will provide ecologically and economicaly favorable characteristics of treated matherials. Further process optimisation in order to improve processing quality could be obtained with new alternative method using microwave energy. Improved characteristics obtained with this method in our previous research confirm its usability in textile finishing processes as well as in chemical modification of wood. Previous research in this field represent worlwide novelty which should be by all means continued.
Project aims and objectives The purpose and aim of the proposed project is to obtain highly valuable and multifunctional treated textile materials that will acquire analogous price on the demanding market. This is the basic condition for the survival of Croatian textile, wood and paper industry on EU market. In textile area experiments will be conducted to obtain multifunctional environmentally friendly textile material which will simultaneously offer dimensional stability, flame retardancy, crease and antimicrobial resistance and will have no effects on human health. Further goal is to obtain chemicaly modified wood that will have reduced shrinking and water absorption as well as to obtain flame retardancy on wood and paper products. One of the equally important goals is construction of a semi industrial microwave device for continuous planar treatment of cellulose materials. The results obtained would be presented in the world best known papers in the relevant field. The most important goal of the project is affirmation of Croatian science in Europe and rest of the World, by presenting the results in international papers so as on International Conferences. It is important to stress that established cooperation with EU and USA experts, so as with their scientific institutions will be continued and expanded.

Project start date: 1 January 2007 Project end date: 31 December 2011 Source of support: Croatian Ministry of Science, Education and Sport, Republic of Croatia Keywords: Protective textiles, Multifunctionality, Smart textiles, Ceramic coatings, Sol-gel process The investigations proposed have been motivated by the fact that people are more and more exposed to various influences from the environment, which can be harmful to their health. Such harmful influences are, for example, UV irradiation, electromagnetic smog, high temperature, fire, etc. Contemporary textile materials for personal protection are required to offer high efficiency, in most cases multifunctionality, as well as a necessary level of comfort. The fabrics used are high-performance ones and interdisciplinary approach is necessary in research dealing with their development and manufacture. The thesis we propose is that the application of contemporary research results in the field of materials can be used to offer a new contribution to the development of multifunctional protective textile materials. The accent will be given to a purposeful surface modification of fabrics, using environmentally friendly agents and processes, which is in accordance with contemporary European trends of research in the field of materials. Special attention will be paid to investigating modifications using the new sol/gel process, combined with preceding ultrasound, laser and plasma treatment of textile surfaces.

New possibilities of manufacturing efficient protective layers will be investigated, using various inorganic substances, including functional layers of nano-dimension made of hybrid inorganic-organic polymers. The aim is to optimise modification parameters of achieving efficient protection from UV and EM irradiation, as well as to increase resistance to abrasion, cutting and heat in particular materials, establishing antimicrobial properties at the same time. Adequate testing procedures will be established to evaluate the newly created materials. New levels of knowledge is expected to be achieved regarding correlation of protective properties and textile fabric composition, as well as the development of practical processes of obtaining aimed fabric modifications and the development of the methods of new material evaluation. New knowledge will contribute to the quality of education in the field of textile materials. Transfer of knowledge into actual industrial production is also expected. The results will be presented on international conferences and will be published in relevant international publications. The obtained results to be obtained could be used to stimulate manufacture of new high-performance textile materials for special purposes in Croatia.
Project aims and objectives The purpose of the investigations is to obtain new knowledge in the field of material development, especially regarding the new composites with textiles as a basic component. The knowledge should be directly applicable in practice, and simultaneously used to improve the quality of education, of both students, young researchers and experts from the industry. The new knowledge is expected to further the development of the Department of textile materials, where the investigations are organised. Based on the knowledge of high-performance materials, that has resulted in the development of the composites, and the role of textile component in them, the possibility will be investigated of obtaining high-performance composites for protection, in which textiles are the basic component. These are new textile materials to be used as protection from harmful influences of the general and working environment in high-risk industrial processes and other activities where people are exposed to risks of mechanical, thermal or chemical injuries, of infection by micro-organisms and even fatal risks from the causes. This is why protective materials are expected to offer high efficiency under various conditions, while the best solutions are aimed at obtaining multi-functional protection by a single material. The purpose of the research is to investigate the solutions that could be applied in textile industry, which could stimulate the introduction of knowledge-based and new-technology-based production in the industry, through adapting the industry to manufacture high-performance composite materials for special purposes. The aim of the investigation is to determine the procedures of obtaining multi-functional textiles for personal protection, simple to manufacture and use. The protective properties will be obtained by modifying the surfaces of the fabrics of various constructions, with the aim to establish optimal modification procedures and processing parameters which could offer efficient protection from individual influences, or, otherwise, protection from more influences. The investigations are supposed to result in solutions for objective evaluation of the effect achieved and the durability of protection as well, but also in the evaluation of the adequacy of the materials for a particular purpose. Adequate testing methods and procedures will be developed, appropriate indicators defined and the correlation of the modification parameters and properties achieved established.

Zagreb and Vodovod, Zagreb Project start date: 1 January 2007 Project end date: 31 December 2011 Source of support: Ministry of Science, Education and Sports, Republic of Croatia Keywords: Wellness finishing of textiles, Determination of harmful substances on textiles, Toxicological and alergenic properties, Environmental protection, Hygiene and effects of textile care, Textile material sample preparation Modern textile finishing processes have to fulfill high demands due to the expectations of new textile materials properties and their persistence during care. Especially interesting in this respect are the new production processes of socks which include implementation of microcapsules that can release active materials for skin moisturizing. Their primal role is prevention of dryness, dandruff and allergenic reactions of the skin. The most suitable analytical methods for determination of durability to washing, friction and sweat will be tested. Durability to washing of products with special properties will be tested with different amounts of anionic and cationic surfactants in liquid detergents. The mechanism of adsorption and desorption, their influence on primary effect of the treatment, and the influence of the pH value and the mechanical way of treatment will be tested. On the ground of the obtained results, analytical methods for determination of micro components in the macro components of textile materials should be proposed, without regards to the specifications of the materials or the method of the treatment. The testing will involve a review of the analytical method of each individual analytical procedure as well as its impact on the obtained information.
The parameters of the analytical procedure will be worked out with the purpose of restoration of historical textile by destructive and non-destructive methods for the preservation of national heritage. European controlling methods of new materials have ethical demands involving the human population health which demands an environmental friendly process. For this purpose the processes of textile finishing and care will be optimized. The possibility of obtaining new preventive properties, which were not previously present on the textile material or improvement of present protection, will be tested. The impact of washing cycles with detergent and UV absorber on pastel colored textile materials made of cotton, polyester and their mixtures on UPF and the shade change will be investigated. The quality control of water and effluents will be based on the determination of micro quantities of potential allergens, heavy metals, pesticides, dyes, and surfactants. The traces of solvents will be controlled on the clothing material and in the air during the chemical cleaning and further treatment processing.
Project aims and objectives The main goal of this investigation is to stimulate ethic ecological demands on the production processes, care processes, and thereby on the utilization properties of the textile materials wherewith it would be possible to get the optimal properties of materials regarding their functional properties by avoiding all possible harmful allergenic and toxicological influences of textile materials to consumers. Elaboration of production and textile finishing processes for the optimal effects (wellness finishing, protection from unwanted changes of utilization properties in texcare, elaboration of pastel dyed textiles laundering in detergent with UV absorber, additional laundering quality – UV protection), formulation of new compositions for laundering for the purpose of avoiding secondary harmful effects in modern conditions with maximal saving of water and energy, more safe treatment with solvents during dry cleaning. By monitoring of harmful inorganic and organic substances that are present in micro quantities on the textile materials, textile accessories, textile wastewaters and finished textile products, new analytical methods would be determined. Sampling procedures, sampling preparation steps, selection of appropriate analytical method and the processing of the obtained result will be optimized. In this investigation the mathematical modes for guiding of analytical procedure will be applied, what is economically justified because the time spend for investigation is much shorter, and the consumption of chemical reagents, energy and emission of harmful substances to the environment reduced. Special contribution will be in development of analytical methods for determination of components present on the historical textile, for the purpose of avoiding the damaging of the textile material during restoration conservation treatments.
Research deliverables The project is scheduled over three years. Eco problems and human ecology, especially presence of heavy metal traces in textile processes and fibres will be investigated and some results will be published. Analytical methods for qualitative and quantitative determination will be developed. The influence of sweat on the heavy metal emission will be tested from colored textile materials.

Possibility and durability of wellness finishing effects particularly on PA pantyhose’s as well as methods will be established. UPF and change in shade of white and pastel colored textiles made from cotton, PET, PA and their blend with cotton during laundering with addition fluorescent compounds in detergent will be researched, too. Hygienic laundering with chemothermic and chemical treatments in order to destroy micro-organisms in compliance with existing recommendations will be done. Potentially irritations of the skin caused by textiles, finishing agents and inadequate rinsing during laundering will be studied. Investigation of anionic, cationic and nonionic surfactant adsorption and desorption influenced by different composition of textile fibres, pH and temperature will be performed. The adsorption and desorption will be studied in order to establish a correlation between zeta potential and swelling capacity of textile fibres.

Keywords: HP Materials, Textile Fibers, Textile Design Contemporary global trends of development in the field of textile fibres and fibrous materials have led to their increased use in various fields of industry and technique. Increase in consupmtion of these types of materials has constantly been recorded and by the beginning of the 21st century technical fibres account for half of all the fibres manufactured. The requirements imposed on fibres and materials in particular fields of application and extraordinary high and specific. These requirements have been met through fibre engineering, i.e. development of new generic types of fibres. It can be assumed that innovative manufacturing and finishing processes, applied to conventional fibres, will result in their added value, so that they can be used to design new fabrics of pre-determined end-use properties. Such improvements in fibre properties and their use in fabric manufacture of added market value and broader scope of application are completely in accordance with the intentions of the European technological platform for future textile and garment, but it can also strongly stimulate the development of Croatian textile industry and its comptetitiveness in the global market. This is supported by the fact that there are considerable research, industrial and raw-material potentials in Croatia, necessary to accomplish the goals. Although domestic production is mostly based on imported fibres, clearly defined modifications of fibre structure and propertties, even for domestic fibres, such as wool, flax, textile regenerates and fibres made from recycled PET, that have been used in Croatian textile industry insufficiently until now, could be used as a starting raw material for the manufacture of high-performance textiles. In this manner, domestic fibrous raw materials would cease being waste material and would become strategic Croatian raw material, as well as a basis of future rational management of natural resources and a step in approaching sustainable development trends, recommended by the European Union and United Nations. The investigations proposed aim at establishing the possibilities of modifying conventional fibres, as well as developing the methods and procedures of objective measurement and evaluation of unconventional textile materials, in accordance with specific rules and requirements for individual types of high-performance textiles, including composites reinforced with fibres of modified properties. The results obtained will offer the construction of high-performance materials based on conventional fibres of added value, as well as the design and optimisation in accordance with the properties of the fibres used and pre-determined high end-use properties.
Project aims and objectives The main purpose of the project proposed is to determine possible interventions and modifications of conventional fibres and textiles, so as to obtain added value and to broaden the scope of their application. This immrovement of fibres and their application in the manufacture of new, knowledge-based innovative textiles of added market value is in accordance with the short term (energy and materials) and long-term (nano-science, new materials, constructions and production processes) strategic trends of research in the Republic of Croatia, strategies of the European technological platform for the future of textiles and garment in the XXI century, as well as with the trends of rational management of raw material resources and the concept of sustainable development, as

proposed by the EU and UN recommendations. Valuable results and new knowledge are expected, especially regarding ecologically friendly and economically feasible production of high-performance textiles through the usage of domestic raw materials in their manufacture. There is a broad diversity of fibres and constructions present in the area of non-conventional textile materials and structures, which makes objective characterisation of their quality a difficult task, we propose to develop new methods, procedures and equipment for testing, so as to enable higher degree of objectivity in quality evaluation. The investigations are planned to initiate the development and optimising of the manufacture of high-performance textiles, matched with their increased and more and more specified areas of application. The results expected to be obtained will enhance the scope of knowledge in the field of textile fibres, materials and textile testing, also valuable in the education of young researchers, knowledge transfer and preparation of future textile engineers for the European labour market.
Research deliverables The results of the investigation will be directly applicable in Croatian textile industry, since new solutions for designing high-performance materials, based on conventional fibres of added value, will be proposed as based on the results of the investigations proposed. As there are some processing capacities still in Croatia (Regeneracija, Kelteks, Vrbenka, Konoplja, LIO, Feniks), working with imported fibres, the system of objective description and evaluation of domestic fibrous raw materials (especially flax and wool), as well as some instructions regarding their environmentally acceptable manufacture, processing and modifications, with the aim of enhancing end-use properties, are expected to create adequate conditions for econbomically feasible manufacture of textiles. Higher content of domestic fibres and raw materials in manufacture of textile would be a sound basis for new development and growth of the Croatian textile industry and its competitiveness in the European and global markets, as well as for realising the principles of sustainable development and rational raw material resource management. Developments and innovations in testing metodology and objective evaluation of relenat properties of the modified fibres and new high-performance textiles will enhance objectivity of testing and evaluation of high-performance technical textiles in general, which is, not only in Croatia but globally as well, a problem with no acceptable solution on the horizon. Some testing methods are expected to be used in production monitoring and control, which could contribute to more reliable and stable manufacture and realising pre-planned levels of quality. The investigations proposed open the way to scientific and professional collaboration with other institutions and with the industry.

Antimicrobial finishing is used on textile fabrics to control bacteria, fungi, mold, mildew and algae present in everyday life, to resolve problems of deterioration, staining, odors and health concerns they cause. It has been long ago recognized that microorganisms, particularly bacteria can negatively influence textile fabrics, especially cotton ones. Most textiles used as clothes, underwear and bedclothes in hospitals and hotels are conducive to cross infection or transmission of diseases caused by microorganisms. During the project time alternative agents for the purpose of antimicrobial treatment will be developed. Two parallel investigations will be performed. Croatian partners will be developing system with polycarboxylic acids. Slovenian partners will be working on grafting of cyclodextrine on textile substrates. Their bacteriostatic activity will be determined using standard methods: JIS L 1902: 2002 and AATCC 147, before and after the washing process. The antimicrobial activity will be tested against gram positive (Staphylococcus aureus) and gram negative

In order to prevent this negative microbial influence knitted material will be treated with several agents of different producers in order to choose the best one and recommend it to the industrial partners. For efficiency control of the treated products, strict conditions of the microbiological laboratory and qualified staff are necessary. For that reason cooperation with Zagreb Public Health Institute and Croatian National Institute of Public Health will be conducted within the project. Further experiments include development of alternative method for antimicrobial treatment, such as microwave treatment. Microwave effectiveness for the purpose of antimicrobial treatment will be determined.

These fabrics contain raw materials in common, and domestic wool and linen yarn as well as glass and carbon yarn will be preferred, but other natural raw materials will be used too, yarns of chemical fibers from synthetic polymers and “smart” yarns. The aim of this research is to find the most optimal raw material and fabric construction and to make a commercially acceptable, qualitative, healthy, comfortable and smart technical fabric. Basic investigations will include: physical-mechanical, thermal, relaxation and elongation properties, dimensional stability, abrasion, effect of sun rays, inflammability, air permeability, water repellency, degradation and the investigation of these properties depending on fabric application. The scope of investigation will include technical fabrics intended for use in civil engineering, transportation and household (3D fabrics for composites, fabrics for seat covers, furnishing fabrics etc.) on which high requirements are set, such as: safety, resistance, comfort and aesthetics. Technical fabrics for industrial purposes such as filter fabrics and fabrics for composites which are of great importance for better utilization and productivity, and still more important in terms of ecological protection of environment, will be investigated. Healthy fabrics in medical terms from natural raw, and generally fabrics with various properties and applications subjected to additional treatments according to health standards. Part of the project will be directed at the investigation and revival of Croatian eco and ethno heritage, including

the manufacture of tapestry, blankets and mats interwoven with art and skill of weaving, using domestic raw materials. The aim of this research is that tapestry authenticity and originality of work of art represent a unique value. The significance of this project is to revive the processing of domestic wool and flax in parallel with the investigation of new constructions and forms of glass technical fabrics, and new materials processed by new technologies. Several technical fabrics replicated in this project will serve as an encouragement for processing domestic wool and flax in smaller batches in karts regions of Croatia.
Project aims and objectives .
.
.
To design and manufacture technical fabrics from natural and new materials, and with their combination, with new methods and manufacturing procedures. To investigate qualitative properties of technical fabrics from natural textile raw materials and to promote the use of primarily domestic wool and linen. Within the basic aim it is necessary to define a numerical model of the manufacturing process and development of new composites so that chemical and physical processes affecting the quality and applicability of composites are investigated and analyzed experimentally. Thereby the influence of particular processes (manufacturing processes, temperatures, outside influences) on the changes of composite properties as well as the interrelationships will be determined.
.
The knowledge gained will be used to define a computer model for the construction of new types of technical fabrics and accordingly new composite materials.
.
To systematize utility and quality values of wool yarn from domestic sheep breeds and to investigate the possibility of the industrial process in blending with other raw materials. To optimize the production of applicable products of domestic raw materials and to promote the revival of the textile ethno heritage in Croatia.
.
.
To investigate the most cost-effective process and the most optimal shares of individual raw materials for the target product with new properties.
.
To include other raw materials with domestic materials with the aim of higherquality, more valuable and attractive products.
.
To manufacture healthy, high-quality, “smart”, comfortable, unique and commercially acceptable textile materials by integrating “smart” materials and new materials dyed with natural dyes.
Research deliverables Manufacture of technical fabrics from different composites with improved properties such as: more healthy (natural fibers), more comfortable (better thermal properties), and more attractive (uneven surface structure made by weaving various densities, fineness, colors and raw materials with different weaving techniques and different finishing treatments). It may be expected that the results obtained will make a
considerable contribution to further development of manufacturing technical fabrics and composites based on them, and that their application range will be expanded. Manufacture of medical fabrics based on natural raw materials and new composites which will be used as part of orthopedic and surgical aids that will dispose of improved properties such as: strength, thermal properties, liquid absorption, elasticity, stability and other properties.

Keywords: Yarns, Knitted and nonwoven fabrics, Structures, Properties, Thermal and vater-vapour resistance properties Further dislocation of the textile production from deveoped countries into Asia is a basic characteristic for the world textile industry today. In the field of technical textiles profound resistance is felt against relocation. An increase in the production of technical textiles is recorded due to a permanent expansion of the application range. It is used in: transportation, industry, medicine, hygiene, household, garment industry, agriculture, fishing trade, civil engineering, sport, safety, ecology etc. Nonwovens make the most significant contribution to the development of technical textiles. Over last decades the technology of nonwovens production has experienced a rapid development, and the production of late years has registered an annual increase of approx. 10 per cent. A significant application range for technical textiles or geotextiles is civil engineering, in particular road building. In addition to woven, knitted and similar structures, nonwovens play a predominant role with a share of approx. 75 per cent in 2005. The most important functions of geotextiles are: separation of weak soil, reinforcement of soil or elements of building structures, filtration and drainage. Geotextile properties are: stability, uniform structure, small thickness, high strength and stretching, porosity, small surface mass and water permeability. Various applications require a more or less marked particular structure and characteristic. The first part of the project will deal with various structures and properties of technical textiles based on nonwoven and knitted structures, in particular on geotextiles. Moreover, manufacturing technologies of technical textiles and knitted materials as well as their controlling parameters will be discussed. Conventional technologies such as: spinning, weaving, knitting and clothing technology will probably not withstand the competitiveness coming from Asia. Besides, relocation of the manufacture of man-made fibres into the Far East is taking place. It is undoubtedly the case that only those disposing of raw materials and enough knowledge to produce and sell high-quality products will have the chances of survival on the market. The investigation of possibilities of manufacturing from coarser sorts of wool which have similar fineness as domestic wool and the investigation of their possible use for products such as carpets and several articles of clothing will be within the scope of this project. The limit of fibre spinnability, typical stress-strain curves, yarn behavior in cyclic examinations of elongation properties, surface friction and yarn hairiness.
Project aims and objectives There are two dominant reasons why the field of technical textiles is dealt with in the project: . Intensive development of technical textiles because of an increase in the application (technical textiles on average of approx. 5.5 per cent, nonwoven fabric approx. 10 per cent). . Resistance to the relocation of the manufacture of technical textiles to the Far East. As a result the manufacture of technical textiles (quantity) in the developed countries accounts for more than 40 per cent of the total production of textiles. The state of the Croatian textile industry should be noted where the classic textile industry has
almost vanished. Two companies Regeneracija and Cˇateks manufacture technical textiles which have their markets. Regeneracija and Cˇateks confirmed their participation in the project. Moreover, the use of domestic wool for various products of higher value is a chalange and obligation. However, today domestic wool is sold as a raw material, and in some regions it is not bought off which is an ecological problem. Based on the above mentioned facts, it is reasonable to deal with the subject matter of technical textiles and yarns and products respectively, such as carpets within the scope of the project. In this way production of higher-quality products is promoted which is the purpose of this investigation. The aims of the investigation are as follows: .
Definition of the interdependence, process parameters and physical-mechanical as wel as other relevant properties.
.
technical nonwoven textile. technical textile based on nonwoven fabric coated with polyurethane (PUR).
. .
technical textile based on knitted fabric from PET and PA coated with polyurethane (PUR) and other technical textiles based on knitted fabric.
.
Definition of the interdependence of raw materials, process parameters and physical-mechanical yarn properties, primarily wool, and the behavior of carpets in dynamic investigations (new instrument required for the project).
.
It will be attempted in case of interest of Regeneracija or other interested parties to investigate thermal properties of wool insulation materials.
Research deliverables Obtaining the new understandings of: . .
.
.
.
.
Thermal and vapor resistance properties of the knitted and nonwoven fabrics. Spun yarns, primarily coarser wool yarns: procedures of manufacturing and defined the controlling parameters of the processes. Structure and properties of the coarser, industrially manufactured wool yarns should be emphasized that can be similar to the yarn spun from domestic wool as far as their properties. Influence of fibres parameteres (finenness, length,.) on limit of spinnability and spun yarn properties. Possibilities of manufacturing carpets from coarser wool fibres will be investigate as well as compressibility of carpets on the new instrument purchased from funds of the project. Processes of manufacturing: technical nonwoven fabrics intended for use in civil engineering, technical nonwoven fabric coated with polyurethane (PUR), technical textiles based on knitted fabric coated with polyurethane (PUR), as well as their structures and properties.

Tvornica mreza i ambalaze, Biograd n/m, Croatia Project start date: 1 January 2007 Project end date: 31 December 2009 Source of support: Ministry of Science, Education and Sport, Republic of Croatia Keywords: Fruit production, Nets, Hail, Viticulture, Plant material, Economic profit Approximately 7 per cent of Croatian fruit is present on the Croatian market. The production and sales of Croatian fruit can be quadrupled and sold at present prices on the Croatian market, but as first class fruit. Over the last ten years The Ministry of Finance received damage reports worth more than 100 million kuna which were caused by hail. Fruit, vegetables, plants, flowers, nursery-gardens, and animals, material resources: houses, agricultural machinery, automobiles and the like get damaged. Up to now rockets have been used to ensure hail protection of fruit and vegetables. On account of a rapid increase in the volume of air transport this technique is less used and is substituted by using protection nets. Several more developed and neighboring European countries have started using nets for the protection of fruit and vegetables against hail. Within the scope of this project systems of applying protection nets in European countries and their use in Croatia would be studied. The emphasis here would be on the safety of orchards, new plants or crops and how to pay compensation for damages by hail. Appropriate protection nets would be designed and manufactured for particular agricultural products and then installed on plantations. Net construction depends on the application so that protection nets of various widths, shapes, colors and structures with special emphasis on the raw material for the production of nets and for shadowing the area to be covered. Across Croatia nets would be offered to the registered fruit growers
for use. During the first year of the project a fruit grower would be offered 1000 m2 of nets without charge with the aim that he buys the same quantity (ratio 1:1) and that he should cover only one part of his plantation. By continuous monitoring orchards all changes under the nets would be analyzed and then compared to the results obtained outside the nets. Over the period of five years relevant conclusions about the use of nets for the protection of fruit and vegetables against hail can be made. It is to be emphasized that the nets, which protect agricultural products against hail, can protect against sun, birds, animals etc. By adequate use of the above mentioned nets it is to expect that yield per hectar will be increased as well as fruit quality. Up to now our fruit growers have collected less than 50 per cent of first class fruit, but using nets it can be expected to increase this limit over 80 per cent. In this way, when Croatia enters into the European Union, we can sell our quality fruits on our market and compete on international markets.
Project aims and objectives The purpose of the investigation is to provide assistance to fruit growers to protect their orchards, both trees and fruits against hail. The aim of the project is to design and make nets that will be helpful and commercially acceptable in the protection of fruits and vegetables against hail. Manufactured nets would be offered to fruit growers for use. During the duration of the project several types of nets for the protection of fruit and vegetables would be developed. The application aim of these protection nets is primarily to protect trees and fruits. In this way fruit growers would increase the quality of collected fruit and yield quantity per unit area. In the long term, when Croatia enters into the European Union, our fruit growers will be able to sell their quality fruits on the Croatian market and compete on the international markets. If we do not do it, the European fruit producers will sell their fruits on the Croatian market without competition. The Croatian fruit growers will not be able to enter into this market because of minor fruit quality. This action will prevent the breakthrough of export fruit on the Croatian market
Research deliverables he whole plan and protocol is mentioned in section 9.2. Therefore only basic characteristics are mentioned here. After 1st year more than 20000 m2 of nets will be installed on different fruit plantations across Croatia. We would collect data on necessary properties of nets for the application in a particular sector or for a particular orchard. Based on the gathered data we would design and make new nets with different physical-mechanical properties. We would come to basic data on the influence of sun beams and weathering on the changes in net characteristics. We would publish approximately five papers. During previous three years we would keep records of all important influences on the fruit quantity and quality. We should come to data on the influence of hail, sun, wind, thrash, birds, animals and the like on the fruit quality and quantity. We would publish a newsletter about the application of protection nets in the cultivation of fruit and vegetables. Publications Not available
