Abstract The main parameters of tensile tests for fabrics and yarns are the breaking force and the elongation at break. The aim of this investigation was to find the relation between the tensile properties of yarns and woven fabrics for different natural raw materials. Manmade bamboo, natural single flax, blended plied flax and natural silk yarns, plied combed cotton yarns, blended plied cotton, and polyester yarns were used for the research. The warp of almost all fabrics, except of one fabric, was from flax. This fabric was woven using blended flax and silk yarns in the warp. Weft yarns were more various – yarns of one kind were used in the weft for certain fabrics; yarns of two kinds were used in 1:1 repeats in other fabrics. It was established that the breaking force for both woven fabrics and yarns increases when the elongation at break increases. The relationships between the tensile parameters of yarns and woven fabrics were established. The results showed weak dependence between the tensile parameters of yarns and fabrics because the coefficients of determination of the dependences are small.

Abstract Owing to growing demand for comfortable clothes, elastane filament yarns are being used in fabrics for several garments. In this study, core spun yarns were produced with cotton fibres and PBT/elastane filament yarns (cotton as sheath material, PBT yarn and elastane as core yarns). Twill woven (1/3 Z) fabrics were produced by using core spun yarns (30 tex) and cotton yarns (30 tex) as weft, and 100% cotton yarn (59 tex) as warp yarns. The fabrics consisting of PBT were washed at 100°C for 30 minutes to gain the elasticity. The woven fabrics’ weight, thickness, elongation, permanent elongation, dimensional stability, air permeability, thermal conductivity, thermal absorptivity characteristics were tested and statistically evaluated. According to the results, the fabrics containing PBT and elastane filaments had similar elongation and shrinkage values. PBT filament yarns have a great potential to produce lightweight elastic fabrics.

This study examines how the counts of PET yarns and spandex fibers influence the properties of tubular knitted fabrics. PET yarns and spandex fibers with different counts are combined to form wrapped yarns, which are then made into tubular knitted fabrics. The surface of the knitted fabrics is observed, after which the knitted fabrics are tested for their tensile strength. The test results show that the tensile strength and thickness of the tubular knitted fabrics both increase as a result of the increasing content of PET yarns; however, the content of either spandex fiber or PET yarns is not correlated with the deformation of the tubular knitted fabrics.

Properties of fabrics woven with wrap spun yarns and equivalent ring spun yarns of Upland cotton have been investigated. Experimental wrap spun yarns were made on a modern, special machine, which produces so-called twistless yarns from staple fibers that are held together by a fine multifilament wrap yarn. The filament wrap used for the experimental yarns was water soluble polyvinyl alcohol. Ring spun yarns were produced conventionally. Each kind of yarn was woven separately as both warp and filling into plain, twill, and sateen fabrics. The water soluble wrap of the wrap spun fabrics was removed during normal wet processing, yielding completely twistless cotton fabrics. The various fabrics were evaluated for their important mechanical properties. Results show that, compared to the ring spun equivalents, the tighter, plain-woven, twistless fabric (of typical average density) fared reasonably well in tensile breaking strength but was slightly weaker in tearing strength; the relatively looser twill and sateen twistless fabrics were significantly weaker in both tensile and tear strengths. Respective fabrics of the two yarn types, however, showed no significant difference in abrasion resistance, although the twill and sateen fabrics made with both yarns generally had lower flex abrasion resistance than the corresponding plain fabrics. Twistless fabrics, like their ring spun counterparts, maintained their tensile and tear properties after repeated laundering.

Abstract Ring, Rotor and Air vortex spinning systems provide yarn with different structures and properties. Each system has its limitations and advantages in terms of technical feasibility and economic viability. 30's Ne, 100%cotton yarns were produced from the above systems and knitted in single jersey machine .The Rotor Spun yarns found with frequent breakage during knitting. Comparatively good knitting performances have shown by the Ring and Air vortex yarns. Tensile, evenness and hairiness of the yarns and bursting strength, abrasion resistance, pilling, drapability and color matching of the knitted fabrics were studied. The Ring spun yarns have high strength, low imperfection, and good bursting strength. It has high 'S3' value. Abrasion resistance of Rotor and Vortex yarns made fabrics were found higher than the ring spun yarns. Ring yarn knitted fabric has high bursting strength, Air-vortex yarn knitted fabric has poor drape due to stiffer yarn structure and the MVS yarn fabric has poor pilling resistance. Rotor, MVS yarns made fabrics have good abrasion resistance. Drapability of Vortex yarn knitted fabrics was poor than ring and Rotor yarn knitted fabrics. Good and equal depth of dye shade was found with Ring and Air vortex yarn made knitted fabrics. Ring yarn knitted fabric has shown smooth feeling than the other two fabrics.

Abstract The destructive effects of sun UV radiation on human skins are now very clear to everyone. Most of the present studies were focused on the fabrics’ structural parameters such as density, warp and weft yarns finenesses, fabric pattern and printing or finishing treatments applied to the fabrics. The aim of this work is achieving a technique through which the produced fabrics possess a higher UV-protection ability. For this purpose, two different metals including aluminium and copper yarns were employed in fabrics production process and their effects on UV-protection ability of the produced fabrics were investigated. Six different fabric samples comprised of either cotton/polyester, nylon yarns as the warp yarns as well as either aluminium or copper yarns as the weft yarns were produced. Using the spectrophotometer technique, which is known as one of the UPF measuring method, the absorbency and reflectivity of fabrics within the specified range of electromagnetic waves (specially the UV radiation) were determined. The results illustrated that the higher UV absorbency was related to the fabric possessing the copper yarns in their structures. It was concluded that the absorption ability of nylon fabrics is higher than that of the cotton/polyester samples.

In this study, stainless steel (SS) filaments are wrapped in Ge fibers to form core-spun yarns. The yarns along with 500 D polyester (PET) fibers undergo weaving, thereby forming functional woven fabrics. The experiment is composed of two parts:yarns and fabrics. The yarns are twisted with TPI of 8, 9, 10, 11, and 12, and then tested for tensile strength and tensile elongation. The yarns possess mechanical properties that are dependent on the TPI—the higher the TPI, the better the mechanical properties. The maximal mechanical properties occur when the core-spun yarns are made of 12 TPI where the maximal tensile strength is 5.26 N and the lowest elongation is 43.2%. As for the functional woven fabrics, they are made of Ge/SS core-spun yarns as the weft yarns and 500 D PET yarns as the warp yarns. The tensile strength, tensile elongation, negative ion release, electromagnetic interference shielding effectiveness (EMI SE), and air permeability tests are conducted, determining the optimal woven fabrics. The 12 TPI core-spun yarns provide the woven fabrics with the maximal tensile strength of 153.6 N and the optimal elongation at break of 10.08%. In addition, the woven fabrics made with 8 or 9 TPI core-spun yarns exhibit an optimal EMI SE of 41 dB, an optimal air permeability of 212 cm3/cm2/s, and an optimal release amount of negative ion of 550–600 ions/cc. The proposed woven fabrics have a broad range of applications, such as functional garments and bedding.

In this study, performance properties of single jersey knitted fabrics made from Aegean cotton, Supima cotton and Giza cotton yarns are investigated. Firstly, Uster parameters and breaking strength of the yarns were examined and then the properties of the fabrics knitted from these yarns were evaluated statistically. The significance levels of the relationship between the measured parameters were determined. Considering the results obtained with the mechanical properties of the fabrics with Uster analysis applied to these yarns, it is seen that the yarns made from Supima and Giza cotton fibers in extra long fiber category have more smooth, less hairiness, contain less neps and the fabrics knitted with these yarns have high mechanical properties.

Abstract Due to the elimination of spinning triangle in compact spun yarns, its mechanical and physical properties differ significantly from ring spun yarns. The difference between the two spun yarns is reflected in the properties of fabrics woven from both. This study is aimed to compare the mechanical properties of fabrics which are produced from yarns spun from 100% Egyptian cotton, Giza 86 on these systems. Statistical analysis revealed that there is no significant difference between both type of fabrics regarding tear strength and abrasion resistance. But in relation to tensile strength, air permeability and stiffness, compact fabrics were superior to ring fabrics.

Abstract Knowing the reflection, transmission, and absorption properties of the yarns from which the woven fabric is made, prediction of a fabric’s UV-protective properties is simple. Using the geometrical properties of monofilament yarns and fabrics, which were determined optically, and following the cover factor theory, we have determined the areas of fabrics covered with no yarns, only one yarn, and two yarns. From a special selected set of high-module polyethylene terephthalate (PET) monofilament materials (e.g., fabrics), we have elaborated a method for determining the reflection, transmission, and absorption of yarns. By first defining the differently covered areas of fabrics, we were able to use them in a mathematical model for calculating and predicting the UV-protective properties of the fabrics. The calculated and measured values of the UV-protective properties of the selected test fabrics were highly correlated, with a correlation coefficient >0.98.

The aim of the research was to produce hollow yarn knitted fabrics with improved thermal comfort properties. Thermal comfort properties and utility properties determine the wearing comfort of textiles and the suitability of a new textile product for a particular application. Both, Thermal comfort properties such as thermal absorptiveness, thermal conductivity, air permeability and utility properties like percent stretch, spirality, bursting strength of core yarn knitted fabrics and hollow yarn knitted fabrics were assessed. A new method was proposed and discussed for producing hollow yarns at fabric stage (in this case knitted fabric) which involved the following steps: - a) Production of ring spun yarns, comprising nylon as a core and cotton as a sheath, using Ring Spinning System. b) Production of knitted fabrics of different knit structures viz., single jersey, rib and interlock using above mentioned yarn. c) Dissolution of core element i.e. Nylon into formic acid to obtain hollow yarn knitted fabrics and this hollow yarn knitted fabrics can be tailored for specific end use. The study covers comparative analysis of thermal insulation properties like thermal absorptiveness, thermal conductivity and others for core yarn knitted fabrics and hollow yarn knitted fabrics and the influence of the count of core nylon filament and the type of knit structures on the thermal properties of the fabrics. Based on the results obtained from the work, it can be stated that hollow yarn knitted fabrics offer numerous possibilities for creating fabric properties which influence their comfort of use.

Not dyed wool yarns and fabrics were treated by ultraviolet radiations, using a medium pressure Hg lamp, in order to obtain a modification onto fibre surface. As consequence, UV treated wool showed increase in metal ions absorption and hydrophilicity, together with improved kinetics of dye absorption under the same dyeing conditions as untreated wool. The surface modification of wool due to UV radiations was confirmed by FTIR-ATR analysis, nevertheless the fibre morphology by SEM analysis was unaffected. Experimental results showed that different kind of dyes are able to give differential dyeing after irradiation, but not all members of the same dyeing class have similar behaviour. Then, a selection of 1:1 metal-complex dyes was chosen to evidence the maximum of difference between irradiated and not irradiated areas. The main interests on wool fabrics were focused on two effects: a) one shade, double face with different depth, higher on treated side; b) two shades, double face with different colour and depth. Moreover it was found that UV pretreatment can be useful to obtain the same dyeing with lower temperature conditions (85°C). Fastness evaluations towards dry rubbing and machine washing at 50°C were also carried out to confirm the feasibility of this alternative dyeing technique; in all experiments carried out with selected 1:1 metal-complex dyes the same score of conventional premetallized 1:1 dyeings was obtained. Dyed cotton yarns and fabrics were treated by ultraviolet radiations, using a medium pressure Hg lamp, in order to obtain a fading of coloured fibre surface. As consequence, UV-treated dyed cotton showed different resistances to discoloration as a function of the selections of reactive dyes used; a selection of cold-reactive dyes (applicable at 60 ° C on cellulosic fibers), having good contrast between UV treated part and untreated, was presented. Industrial applications for discontinuous and continuous treatments (yarns or fabrics) and new proposal are also presented, with an economical evaluation of the processes (feasibility, reliability and effective costs).

About a decade ago an attempt to build a viable wild silk industry, prompted by the discovery of the naturally available wild silk cocoons in the North West Province of South Africa, was made and a degumming plant was established in the Ganyesa village. The challenges faced in that establishment soon brought the developments to a standstill and cited among the problems was the lack of designer input in the production stages, which resulted in poor quality products. Focusing on the design problem the intention of this research is to explore a more effective design and production method for the wild silk fabrics. Through assessing the previously produced fabrics in order to identify their limitations, and by experimenting with innovative fabric production processes, a suitable aesthetic quality can be added to the final products. Starting with the investigation of current trends and choosing a design theme as a guide for the production process, fabric samples intended for use in upholstery of home furniture are developed. With the objective of successfully achieving a balance between aesthetic appeal and suitability for the intended end use, the fabrics are subjected to performance assessments based on internationally recognised standards. From the findings of this research it is therefore envisaged that, from the design aspect, proper redevelopment of the South African wild silk industry could encourage further involvement from textile designers. This would bring more improvement to the fabrics produced and encourage their use in different applications.

Cette thèse s’inscrit dans le cadre du projet européen 3D-LightTrans ayant pour objectifs la fabrication à grande à échelle et à bas coût de pièces composites. Pour parvenir à ces objectifs, des semi-produits sous forme de tissus 3D de mèches comélées ont été réalisés. Le but de ces travaux est de caractériser le comportement mécanique de ces tissus en vue d’analyser leur formabilité et d’être en mesure de prédire leur comportement pendant les processus de mise en forme utilisés lors de la fabrication des pièces composites. Le premier objectif de ces travaux était de caractériser expérimentalement le comportement mécanique des tissus 3D. Après avoir effectué un état de l’art ayant permis de définir les types et paramètres d’essais à utiliser pour la caractérisation du comportement des tissus, l’analyse des résultats de ces différents essais a permis de mettre en évidence les spécificités du comportement des tissus 3D. Le deuxième objectif des travaux était de modéliser le comportement des tissus par une approche numérique. Le choix s’étant porté sur une approche à l’échelle mésoscopique, le comportement mécanique des mèches comélées a été caractérisé expérimentalement. Les limitations du logiciel GeoFab quant à son utilisation pour la génération de modèles CAO de mailles élémentaires de tissus 3D ont été identifiées. Des améliorations permettant de répondre à ces limitations ont été proposées et leur faisabilité démontrée. Un modèle CAO d’une sous partie de la maille élémentaire d’un des tissus a alors été généré. Après avoir modélisé le comportement des mèches comélées en se basant sur les résultats de leur caractérisation expérimentale, des premières simulations éléments finis ayant permis d’obtenir des résultats encourageants ont été réalisés
This thesis is part of the European project 3D-LightTrans whose objectives are the large scale and low-cost manufacturing of composite parts. To achieve these goals, semi-finished products in the form of 3D fabrics of commingled yarns were produced. The purpose of this work is to characterize the mechanical behavior of these fabrics in order to investigate their formability and be able to predict their behavior during the forming processes used for the manufacturing of composite parts. The first objective of the work was to characterize experimentally the 3D fabrics mechanical behavior. A state of the art was realized in order to define the types and test parameters to use. The analysis of these test results allowed to highlight the specific 3D fabrics mechanical behaviour. The second objective of the work was to model the fabrics behavior using a numerical method. A mesoscopic scale approach having been selected, experimental characterization of the commingled yarns mechanical behavior was necessary. Then, GeoFab software limitations on its use for the generation of CAD models of 3D fabrics unit cells were identified. Improvements to address these limitations have been proposed and their feasibility was demonstrated. A CAD model of a sub part of one of the fabrics unit cell was then generated. After having modeled the commingled yarns behaviour using experimental results, finite element simulations were performed on fabric CAD model and first encouraging results were obtained

Resumo:

Um tipo de composto têxtil, comumente chamado de membrana têxtil, tem sido empregado, nas últimas décadas, como parte de um sistema arquitetônico usado para a cobertura, fechamento e/ou proteção de espaços públicos e privados em vários países do mundo. O termo membrana está relacionado com o fato de o material permanecer tensionado e separar dois ambientes que se interagem. Essa solução arquitetônica é comumente conhecida como arquitetura têxtil, especialmente quando se trata de estruturas tensionadas; o termo é usado por muitos profissionais em todo mundo, apesar de não existir uma unanimidade de opiniões sobre os conceitos envolvidos na definição do termo e o que ele abrange. Na maior parte dos casos, as obras geradas são muito atraentes, práticas e funcionais, com características, formas e tamanhos diversos, dependendo da necessidade a ser atendida. Quando bem projetadas, integram-se perfeitamente ao ambiente por terem formas orgânicas e passarem uma imagem de leveza, fluidez e modernidade. São dois os tipos de membranas têxteis mais usados: 1) um grupo de membranas cujo tecido estruturante é um tecido de poliéster recoberto em ambos os lados por uma camada de cloreto de polivinila (PVC), e 2) um grupo de membranas feitas com tecidos de vidro recobertos com politetraflúoretileno (PTFE). O foco principal deste trabalho são as membranas de poliéster/PVC usadas para estruturas tensionadas. Os tecidos usados nessa gama estão enquadrados na categoria denominada tecidos técnicos, e são formados por fios compostos por filamentos de poliéster de alta tenacidade de diferentes tipos, gerando vários artigos com características técnicas distintas e, consequentemente, membranas com diversas especificações e comportamentos diferentes na aplicação final.Este estudo traz uma visão geral sobre o assunto no mundo e um panorama mais detalhado para o Brasil, abordando definições, termos usados, materiais, fornecedores, especificações, tipos de produtos e acabamentos, normas, reciclagem e meio ambiente. A beleza e modernidade são apontadas como as principais qualidades desse tipo de cobertura. As expectativas são de crescimento dessa aplicação para os próximos anos. Porém a falta de conhecimento e a complexidade técnica desse tipo de solução é um problema a ser solucionado para que melhores resultados sejam atingidos e ela possa realmente ser considerada uma solução viável e adequada para o país.
The type of textile compound, commonly called textile membrane, has been employed in recent decades, as part of an architectural system used for covering, closing and/or protection of publics and private spaces in many countries around the world. The term membrane is related to the fact that the material remains tensioned and separating two interacting environments. This architectural solution is commonly known as \' textile architecture \', especially when tensile structures are involved; this term is used by many professionals worldwide, although it do not exist a unanimity of opinions regarding the concepts involved in the definition of the term and what it encompasses. In most cases, the structures generated are very attractive, practical and functional, with different characteristics, different shapes and sizes, depending on the requirements to be met. When well designed, they will be seamlessly integrated with the environment by having organic forms, giving a feeling of lightness, fluidity and modernity. The two types of textile membranes commonly used are: 1) a group whose structuring material of the membrane is a polyester fabric coated, on both sides, with a layer of polyvinyl chloride (PVC), and 2) a group of membranes made with glass filament fabrics coated with polytetrafluoretilene (PTFE). The focus of this work is the polyester/PVC membranes used for tensile structures. The fabric used in this range is framed within the category named \'technical fabrics\', and are composed by different kinds of high tenacity yarns of polyester filaments, generating several articles with different technical characteristics and consequently, membranes with different specifications and different behaviors in the final application. The study provides an overview of the subject in the world and a panorama slightly more detailed for Brazil, covering definitions, terms, used materials, suppliers, specifications, product types and finishes, recycling and environment issues. The \' beauty \' and \' modernity \' are cited as the main qualities of this type of covering. There are expectations of growing of this application for coming years. But the lack of knowledge and the technical complexity of this kind of solution is a problem to be solved, so that best results can are achieved and it can really be considered a viable and appropriate solution for the country.

AbstractFiber-reinforced plastics (FRP) are increasingly popular in light weight applications such as aircraft manufacturing. However, most production processes of thin-walled FRP parts to date involve the use of expensive forming tools. This especially hinders cost-effective production of small series as well as individual parts and prototypes. In this paper, we develop new possible alternatives of highly automated and die-less production processes based on a short review of current approaches on flexible thin-walled FRP production. All proposed processes involve robot guided standard tools, similar to incremental sheet metal forming, for local forming of the base materials. These include woven glass fiber fabrics which are locally impregnated with thermoset resin and cured using UV-light, woven commingled yarns made out of glass fibers and thermoplastic fibers which are locally heated and pressed, as well as pre-consolidated thermoplastic organo sheets which require selective heating for forming. General applicability of the processes is investigated and validated in practical experiments.

This paper introducing some recent research progress consists of two parts: the shear deformation analysis and Poisson’s ratios for woven fabrics. The analytical methods of the shear moduli and Poisson’s ratios for woven fabrics will enable more rigorous studies on such important issues of fabric bending and draping behaviors. A new mechanical model is proposed in this paper to evaluate the shearing properties for woven fabrics during the initial slip region. Compared to the existing mechanical models for fabric shear, this model involves not only bending but also torsion of curved yarns. Analytical results show that this model provides better agreement with the experiments for both the initial shear modulus and the slipping angle than the existing models. Furthermore, another mechanical model for a woven fabric made of extensible yarns is developed to calculate the fabric Poisson’s ratios. Theoretical results are compared with the available experimental data. A thorough examination on the influences of various mechanical properties of yarns and structural parameters of fabrics on the Poisson’s ratios of a woven fabric is given.

This paper is concerned with the mechanics of woven fabrics under tensile loading. The yarns are treated as elastica. The yarns bent into shape for both warp and weft are assumed to be elastic, homogenous, and weightless. During deformation the yarns are subjected to bending, extension and transverse compression. The initial geometry of the yarns in the fabric, under no external loading, is first obtained using a force-equilibrium method based on Love’s ordinary approximate theory, a generalisation of the Bernoulli-Euler theory of elastic rods. A non-linear boundary-value problem with a system of five differential equations has been formulated and solved. Application of load will further change the shape of the bent yarns due to bending and stretching. For a yarn with given initial geometry, as obtained by the force-equilibrium method, the solution of the deformed configuration is obtained from the solution of two nonlinear differential equations using appropriate boundary conditions. The formulation of the latter problem is based on the energy method. The sum of the energy terms due to bending, stretching together with the potential energy due to the applied load provides an expression for the total energy of the system. The variation of the total energy in terms of the variations of two parameters is then obtained, using the techniques from calculus of variations. One parameter described the deviation of the bent yarn from a straight line while the other is the length as measured along the yarn axis. This leads to a set of differential equations that fully describe the deformed yarns. The models, initially developed for plain weave, are being currently extended to non-plain weaves and 3D woven fabrics.

Abstract Knit products are widely used in our daily lives because of their excellent elasticity and warmth retention properties. Among such knit products, many of the products we wear on a daily basis are usually composed of flat knitted fabric, which is the basic structure of knitted fabric. This unique structure of flat knitting gives knit products a high degree of elasticity. However, a defect called Yotari often occurs during the creation of flat knitting. Since the appearance of knit products are impaired by this defect, there is a need to predict the occurrence of such defects and to investigate their causes. The purpose of this study is to predict the occurrence and determine the cause of the problem by dynamically analyzing the yarns knitted on a knitting machine. In this paper, we examine the hypothesis of the cause of Yotari. First, we formulate the yarn based on physical constraints. Next, we formulate the contact and friction between the yarn and the knitting parts. Finally, we dynamically simulate the behavior of the yarn as it is woven by the knitting parts.

Life Cycle Assessment (LCA) studies represent the scientific approach for elaborating modern policies and supporting management decisions in the field of Sustainable Production and Consumption. The goal of many LCA studies undertaken for research are related to an exhaustive comparison of a modern, innovative product or process with respect to an initial, conventional one. This paper deals with such an approach for fabric based electromagnetic shielding. Electrically conductive textile fabrics are used in applications of electromagnetic shielding. Two basic types of technology for imparting electro- conductive properties to textiles are available, namely: insertion of conductive yarns in the fabric structure and coating with conductive layers. Magnetron plasma coating is a modern technology for achieving thin metallic layers on fabrics. Therefore, we focused the LCA study to the comparison between cotton woven fabrics with inserted conductive yarns out of stainless steel in warp and weft direction and cotton fabrics coated with thin layers of copper by magnetron plasma laboratory equipment. Functional unit of the comparative study was one square meter of EM textile shield with 5.2 dB at 1 GHz. A modelling of the fabric with inserted conductive yarns was performed in order to reach same shielding effectiveness at a certain frequency, as in the case of the coated fabric. Inventory data was collected for the fabric with conductive yarns from the textile company SC Majutex SRL, while for the plasma coated fabric from INFLPR. Impact assessment was performed by INCDTP, by using the LCA software SimaPro7 and the data basis EcoInvent 3.0. Interpretation of results shows that weaving of conductive yarns has a smaller impact on the environment than magnetron plasma coating using laboratory equipment, in a ratio of 1:2. This fact is explained by the industrial process of weaving as compared to laboratory process of coating, whereas brings the idea that upon utilization of industrial magnetron equipment for coating one may achieve in the end better environmental impact due to the process optimization for large area plasma processing.

Software CAD / CAM is professional software for design of woven fabrics and for manufacturing technology Using these systems is efficient if the designers have solid knowledge of the technology and the fabrics structure. In the training of students, CAD CAM system for weaving can be used with successfully as an educational software, if is using all the functions of the program. In this paper we present the resources it has CAD CAM software Arah Weave, in the above presented sense. It is relatively easy to construct a fabric. The whole art is to combinate these elements: - weave (the way the yarns interlace); - warp and weft pattern; - yarns count and your structure; - warp density and weft density. Still, sometimes we will be surprised by what a simple interplay of these factors will produce, in the fabric structure and appearance. To play with these settings, without constrains and with minimale expenses, is the very reason why we should use the Arah Weave software in the instruction processe of the students. Another advantage of using such program is the simulation of the fabric. The simulation mode, shows the fabric in real density with respect to finished fabric Arah Weave programm has a database which stores information for the preparation of the students. All this data are stored in the subdirectories, like following : -fabrics directory-contains all information relevant to 550 fabrics: colors, yarns,weave, density and other technical details; - yarns - contains yarn colors, count, twist, structure; - weaves - contains12000 of weaves; -img- contains images for jacquard conversion or for overprint simulation, model images for usage with Arah Drape, fabric simulation for usage in Arah Drape. This information is used by students as a model and an inspiration source.

Electromagnetic shielding is needed to protect human beings from undesired non-ionizing radiation and to protect electronic equipment from EM interferences. Shielding solution of Electromagnetic Compatibility domain is tackled nowadays by modern manufacturing methods of flexible textile fabrics with electrically conductive properties. Our research focuses on the additional electromagnetic shielding effectiveness (EMSE) rendered by plasma coating of flexible woven fabrics with inserted conductive yarns. EMSE was computed for an experimental plan formed of plasma coating with Copper and Stainless steel with thicknesses of 400 nm and 1200 nm on both sides of woven fabrics with inserted conductive yarns of stainless steel and silver. An additional EMSE of 5-20 dB on the frequency range of 0.1-1000 MHz was achieved by plasma coating. This proves the enhancement of the shielding properties by magnetron plasma coating, without altering the bulk properties of textile fabrics, such as flexibility and mechanical resistance. The paper presents EMSE results in relation to fabric structure, raw metallic materials and frequency of the incident electromagnetic field.

Kinesiology tape is a thin, flexible relatively new intervention for treating a variety of injuries such as relieving pain, reducing swelling and inflammation, and providing support to joints and muscles. However, there is little study to support the material composition and structural properties as well as the physical strength and comfort properties of different kinds of kinesiology tapes. Therefore, in this study, numerous testing was conducted to measure the structural, physical strength, and comfort properties. The experimental results show that kinesiology tapes are non-linear elastic fabric where the backsides of the fabrics are coated with an acrylic adhesive. It was also found that warp yarns of the fabrics are mostly based on core-spun elastic yarns and weft yarns are rigid cotton yarns. The physical strength of the kinesiology tapes were found from 104N to 272N which is unusual due to their structural material properties and fabric thickness. Air permeability, water vapor permeability, and thermal conductivity characteristics are mainly affected by the compact layer of acrylic adhesive on the surface of the fabric that might be significantly increased under tensile extension resulting in air permeability, water vapor, and thermal conductivity properties will be increasing that can positively affect wearer comfort.
