Effect of weave parameters on air resistance of woven fabrics produced from compact doubled yarn

Abstract

The effect of weave parameters, namely crossing-over firmness factor (CFF), floating yarn factor (FYF) and fabric firmness factor (FFF) and geometrical properties such as areal density, thickness and porosity of woven cotton fabrics on air resistance has been studied. A series of cotton woven fabrics comprising eleven weave structures and having common count in warp & weft and fabric sett has been produced. Samples are divided into four groups on the basis of their weave and geometrical parameters each group designed to represent a particular effect. Air resistance is determined by performing the standard test KES- F8 – API. The results show a strong correlation among CFF, FYF and FFF with air resistance. Fabrics having long floats are characterized by lower air resistance and those having no float display higher air resistance. Thickness is found to be well correlated with air resistance. Thus, in addition to CFF, FYF and FFF, thickness should also be taken into consideration for predicting air resistance of fabrics.
