Investigation of the effect of different structural parameters of cotton woven fabrics on their air permeability

Abstract

This study presents an investigation of the effect of different structural parameters of cotton woven fabrics on their air permeability. For this purpose, 24 fabric samples having different structural properties were obtained by using three different weave types (plain, 1/3 twill and 1/7 sateen), two different weft yarn counts (Ne 20/2 and Ne 70/2) and four different yarn twist levels (120, 360, 600, and 840 turns/m). Cotton Ne 50/1; 150 turns/m warp yarns and 40 threads/cm warp density were used in all fabric samples. The relationship between the fabrics structural parameters like weft yarn count, weave type, yarn twist number and air permeability behavior are investigated. It has been shown that the increase of yarn counts and yarn twist led to an increase in air permeability values of cotton woven fabrics. Also, cotton woven fabrics with 1/7 sateen weave have the maximum air permeability value; these fabrics are followed by the fabrics having weave types of plain and 1/3 twill in spite of high weft density.
