The aim of this study was to determine the thermophysiological comfort behavior of fabrics based on copper wire that can be used for electro-textile applications. For this purpose, hybrid folding yarns were produced by twisting cotton/polyester yarn with copper wire. These electrically conductive hybrid yarns were then used to produce upholstery fabrics with different weave types as plain, 2/1 twill and sateen weave in three different density levels as tight, medium and loose. Thermophysiological comfort properties such as air permeability, thermal and water vapor properties of the hybrid fabrics were measured. In addition, the heat transfer properties of the fabrics were investigated with thermal camera videos, and porosity values were determined from microscope images. In this way, the main thermophysiological comfort properties of the basic electro-textile structures were revealed. According to the results obtained, it was found that the use of conductive wire in the fabric structure did not negatively affect the thermophysiological comfort properties of the fabrics, and fabric density was a determining parameter in relation to the thermophysiological comfort properties of the fabrics. The obtained results of this study may be used to improve the design of electro-textile structures taking into account the thermophysiological comfort.

Air permeability is one of the thermal comfort properties of clothing and fabrics. This study evaluated the air permeability properties of summer cooling towels of different brands available in the market, “Perfect Fitness”, “N-rit” and “Cooldyxm” and an anonymous ice towel. The air permeability function of the cooling towels was evaluated instrumentally. Other than the air permeability property, other fabric specification such as fiber composition, fabric type, fabric weight, fabric thickness, yarn linearity and fabric density were measured. Some specifications were found to have good statistical correlation with the air permeability. Based on the experimental results and statistical analysis, the sample of Perfect Fitness was found to have the poorest cooling effect, whereas N-rit, Cooldyxm and Ice Towel samples had comparable air permeability properties. The best performance of air permeability was seen in N-rit sample. The underlying reason could be ascribed to the fabric structure and thickness. This study can provide some information for choosing cooling towel for practical use.

Pressure Switch

In this paper has shown that the three-dimensional hollow weaving technique enables to produce a textile pressure sensor in one continuous process. Based on the multilayer fabric principle, the hollow woven fabrics can be created by connecting adjacent layers of the fabrics according to certain rules. The appropriate fabric structure has been selected and the three-layer weaving technique was used to make the textile pressure switch. The fabric structure is selected to ensure that the top and bottom layers are kept at a distance from each other. The electrically conductive tracks were embedded in the hollow structure of the fabric in bottom and middle layers. Three conditions must be fulfilled in order to create the textile switch: a) the fabric in normal condition keeps the shape required, i.e. the conductive elements are physically separated from each other; b) when the fabric is pressed, conductive elements are in contact, i.e. the switch is now in an electrically on state; c) after the pressure has been removed the fabric returns to its original position, i.e. switch is in an electrically off state. The behavior of the electrically conductive yarn and conductive tracks were tested in various ways. The stainless steel yarn woven in particular way can be used to create woven conductive tracks. Example of application: the pressure sensitive woven rug, the whole area or part of which acts as the pressure sensor or simple switch. The pressure switch in the floor coverings can turn on alarm systems or indicator lamps in the floor or wall coverings for guidance systems in public buildings.

Comfort is one of the most important aspects of clothing. Air permeability, one of the comfort charectaristics of fabrics, depends mainly on the fabric structure, which can be described by weave and yarn density. In this study, 16 worsted woven fabric samples were produced for winter clothing using eight frequently implemented weave types together with one warp density (28 ends/cm) and two weft densities (25 and 28 picks/cm). Additonally, semi-dull finish was applied on raw fabrics. Results revealed the effect of weave, weft yarn density and finishing process on air permeability of woven fabrics. 2/2 twill woven fabric, whose porosity is the lowest, have the lowest air permeability properties, therefore it is more convenient for winter clothing. It is observed that in all weave types, an increase at weft setting caused to decrease in air permeability and porosity values. Finishing process also leads to decreasesin porosity thereby to decrease air permeability property

In this paper was analysed the tasks of construction preparation in the production of women’s pants and the properties of woven fabrics, which affect the thermophysiological and ergonomic comfort. Five different models were observed, which have different cutting lines at the front and back of the sock, different pockets and other details. The duration of construction preparation work in the conventional method and application of CAD system OptiTex were analysed. The ergonomic comfort of the tested models was subjectively evaluated in six differnt body positions, and the results were presented as mean with a number on a scale of 1 to 5. Seven woven fabric samples were used of same composition cotton 67 % and polyester 33 %, the same weave of canvas-rips. The correlatio of structural parameters was analysed: woven fabric density, warp and weft density, with material characteristics that are essential for thermophysiological comfort - air permeability and power of water absorption. It was noticed an increase air permeability, with a decrease in the density of the woven fabric, in most of the samples tested. This is explained by the existence of larger chamber in the structure of the lower density woven fabrics. With decreasing woven fabric density there is a tendency to slightly increase the power of water absorption.

Electrically conductive fabrics were prepared with interlacing polyester yarns and wrapped yarn of polyester/NiCr filament. The wrapped yarns are lined in different distance along filling direction, and the effect of distance on electrically conductivity of fabrics with plain weave is analyzed. In addition, wearing properties including fabric thickness and air permeability of such fabrics are also tested. The results show that surface charge density decrease with number increase of wrapped yarns in filling direction. When wrapped yarns are arranged at 3 yarns/ 6 cm for twill weave, the fabric density and air permeability increase with fabric density.

This research investigates the effect of fiber, yarn and fabric variables on the bagging behavior of single jersey weft knitted fabrics interpreted in terms of bagging fatigue percentage. In order to estimate the optimum process conditions and to examine the individual effects of each controllable factor on a particular response, Taguchi's experimental design was used. The controllable factors considered in this research are blending ratio, yarn twist and count, fabric structure and fabric density. The findings show that fabric structure has the largest effect on the fabric bagging. Factor yarn twist is second and is followed by fabric density, blend ratio and yarn count. The optimum conditions to achieve the least bagging fatigue ratio were determined.

This research aims to innovate a new fabric structure, which could be used as a bed cover based on double honeycomb fabric with self-stitching. The honeycomb air pockets were aimed at facing each other to form closed small air chambers which work to sequester the air. The double fabric increases fabric thickness. Thus, the opportunity to improve thermal comfort could be achieved. A number of samples were produced with different densities and counts of weft yarn. Thermal insulation and water vapour permeability were measured and compared with bed covers produced from reversible weft backed structure. Geometrical properties, abrasion resistance, and air permeability were also measured. The results showed that the innovated structure had higher values of thermal insulation than reversible weft backed structure at certain weft counts and densities.
