Investigation of thermal comfort properties of zinc oxide coated woven cotton fabric

In this paper, we investigated thermal comfort properties of twill weave cotton woven fabric coated zinc oxide layer in Roaches high temperature sample dyeing machine in gentle conditions. The effect of coated film structure on thermal comfort properties of the fabric was characterized using SEM observation, EDS analysis, and Permetest instruments. EDS analysis and SEM images of the ZnO coated twill weave cotton fabric proved that ZnO coating layer which has significant effects on thermal comfort properties was successfully synthesized on the fabric surface by covering the pores of the twill weave cotton fabric. Results showed that thermal resistance of ZnO coated fabric increased approx. 36–52%, while thermal conductivity is decreased approx. 27–34% and WVP is decreased approx. 22–28%. Further studies have started and in progress to evaluate wash fastness, wear performance, abrasion properties, and fabric handle properties.     

Non-linear Theory of the Biaxial Deformation of a Triaxial-weave Fabric

A new theory predicting the biaxial tensile properties of a triaxial-weave fabric is presented. This theory is based on the plain-weave theory developed by Kawabata, Niwa, and Kawai in 1973 and improved by Kawabata in 1984. The basic structures of the fabric are (i) the thread-spacing of two warp threads and one weft thread, (ii) the weave-crimp shrinkage of the three threads, and (iii) the crossing angles between these threads. The yarn properties applied in this theory are the tensile properties, the lateral-compressional properties, the bending property, and the yarn-crossing-torque property. The biaxial tensile properties of the triaxial-weave fabric are then derived by solving an equilibrium equation of the forces acting at a thread-crossover point. The prediction and the experimental result coincide well over the wide range of deformation from the small-strain region to the finite-deformation region near breaking strain. The theoretical analysis shows that the yarn lateral-compressional properties have a significant effect upon the fabric tensile properties, and the effects of the yarn-bending and crossing-torque properties are negligibly small except for the very small-strain region. It is also shown that the tensile properties of the triaxial-weave fabric are much more isotropic than those of the ordinary woven fabric because of the symmetrical structure which appears for every 30° angle rotation of the fabric in the plane of the fabric, and it is demonstrated that the tensile properties of the triaxial-weave fabric are, in fact, almost completely isotropic.

Simultaneous Optimization of Woven Fabric Properties Using Principal Component Analysis

The yarn structure and fabric interlacing pattern are determining parameters for fabric properties. The current study focusses on the multi-response optimization of certain fabric properties like shrinkage, areal density, thickness, flexural rigidity, and bending modulus using principal component analysis for optimum properties. Yarn twist (four different levels), fabric weave design (plain and twill), and yarn type (carded and combed) were the variables of the study. The Taguchi approach of the orthogonal array was sued for designing the experiments, and eight different samples were produced. The yarn twist and fabric weave design were found to have significant effect on these properties of the fabric. Furthermore, using analysis of the variance method, contribution% of parameters to these properties was determined.     

Objective evaluation of terry fabric hand

The subjective evaluation of fabric hand restricts the scientific understanding of the fabric properties and also limits the application of designing engineering principles to develop high-quality fabrics. Hence, an objective hand evaluation system for terry fabric has been devised in this research work. The sensor of KES-FB4 instrument, used for measuring frictional properties, was modified and the results were used for the development of new hand equations. Four primary hand equations and one total hand equation have been developed using low-stress mechanical properties of terry fabric. It is observed that fabric weight and thickness, compression and surface properties can predict the hand behavior of terry fabric very well. The objective hand values calculated by the newly developed hand equations correlate very well with the subjective hand values.
