Turkish traditional Buldan weavings are known as special fabrics in terms of providing comfortable clothes which are known to be natural and healthy in Denizli, Turkey. The research presented in this paper assesses the effects of different fabric structural parameters of Buldan fabrics on comfort properties such as thermal resistance, thermal absorptivity, water vapour permeability and air permeability. Five different Buldan fabrics woven with different fabric structural parameters were produced. According to test results, cotton/Tencel Buldan fabrics indicated similar comfort properties with the 100% cotton Buldan fabric properties. Additionally, the lowest thermal absorptivity was observed from 100% cotton Buldan fabrics which give the warmth feeling among the evaluated samples.

Absorption Properties

In this study, the effects of physical parameters on the acoustic absorption properties of woven fabrics were studied. The acoustic absorption properties of 24 kinds of woven fabrics with different structural parameters were measured and analyzed. Multiple linear regression models have been established to characterize the relationship between acoustic behavior and various physical parameters. It has been found that the acoustic absorption properties were mainly determined by the perforation ratio and air permeability. The decrease in perforation ratio and air permeability results in an increase of acoustic absorption properties of woven fabrics. Furthermore, three woven fabrics were used to validate the proposed multiple regression models. The established models could well predict the acoustic absorption properties of woven fabrics where the correlation coefficient is higher than 0.77 with air gaps of 1, 2, and 3 cm, respectively.

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.

In this study, air permeability, water vapor permeability and wicking properties of certain woven fabrics, which are important comfort properties for clothes and garments, have been investigated. The effects of raw material (modal, Lyocell), weave pattern (plain, 2/2 twill, 1/3 twill, 2/2 matt) and weft yarn density (18, 22, 26) on these properties have been analysed graphically and statistically. The comfort characteristics of fabrics (permeability and wicking properties) are closely associated with the changes in their structural parameters: 2/2 matt and plain woven fabrics, where porosities are high, have better permeability and wicking properties. Increasing weft yarn density lead to decreases in porosity, resulting in decreased permeability and wicking properties. Increasing yarn twist increased the porosity of the fabrics. Lyocell fabrics showed improved permeability and wicking properties over modal fabrics due to Lyocell fibers’ high percentage of fibrillary structure.

Abstract Seat upholstery fabrics for vehicles are crucial products as technical textiles in motor vehicles make up approximately 15% of the total manufactured technical textiles worldwide and more than 50% of the production belongs to the woven fabrics because of their appropriate properties for this application. The current work presents the comfort-related properties of the woven fabrics designed to be used in automotive seat upholstery. For this aim, double-layered woven fabrics were produced with four different process variables such as bottom layer pattern, number of interlacing warps in a unit report, number of interlacing picks per top warp, and number of weft skips by using Taguchi experimental design. Besides handle related properties, such as circular bending rigidity, surface roughness properties, and thermo physiological comfort related properties that include air permeability, thermal resistance, and moisture management properties were measured and analyzed based on Taguchi experimental analysis.

AbstractThis study investigates physicochemical impact of ultrasonic irradiations on surface topography of woven fabrics. In a simultaneous in-situ sonochemical method, the synthesis and coating of zinc oxide nanoparticles (ZnO NPs) on woven textiles were successfully achieved. Different instruments i.e. Alambeta, moisture management tester, air permeability tester and permetester were utilised during experimentation for thermal evaluation, moisture transportation and air permeation. The results regarding thermophysiological comfort of ZnO coated fabrics were evaluated on the basis of thickness and ZnO NPs coated amount on fabrics. In addition, the achieved results depict the impact of sonication (pressure gradient) on surface roughness of cotton and polyester. The coating of ZnO NPs on fabrics, crystal phase identification, surface topography and fluctuations in surface roughness were estimated by inductively coupled plasma atomic emission spectroscopy (ICP-AES), X-ray Diffractometry (XRD), ultrahigh-resolution scanning electron microscopy (UHR-SEM) and energy dispersive X-ray (EDX). Moreover, thermophysiological properties i.e. thermal conductivity, absolute evaporative resistance, thermal absorptivity, air permeability, overall moisture management capacity and relative water vapour permeability of untreated and ZnO treated samples were evaluated by standard test methods.

The main objective of the present study was to investigate the increase in the electromagnetic shielding effectiveness (EMSE) of a set of five variants of three-dimensional (3D) warp interlock woven fabrics containing silver multifilament yarns arranged in a 3D orthogonal grid. The EMSE enlargement as a factor of increasing the quantity of the conductive material per unit area was investigated. The quantity of the conductive material per unit area in a 3D woven fabric can be enlarged by increasing either the yarn undulation or the number of conductive yarn systems, while the yarn density and yarn fineness are fixed. Thus, the binding depth of the conductive warp was gradually increased for the first four variants in order to increase the yarn undulation. Alternatively, the conductive weft system was doubled for the last variant with the aim of increasing the quantity of the conductive component. It should be noted that changing the weave structure requires less effort and energy while keeping the same threading of warps in the reed compared to altering the warp density. The EMSE was measured in an anechoic chamber and the shielding was satisfactory for all the variants in the frequency range of 1–6 GHz (19–44 dB). The results revealed that increasing only 7% of the waviness degree of the conductive warps led to 17% EMSE improvement due to increasing of the conductive yarns through the thickness of the variants. Moreover, no upward EMSE was detected for the last variant, despite the fact that the conductive weft system was doubled.

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.
