An investigation of the effect of weave parameters, namely Crossing Floating Factor (CFF), Floating Yarn Factor (FYF) and Fabric Firmness Factor (FFF) and the geometrical properties of woven cotton fabrics such as the areal density, thickness and porosity on air resistance is reported. A series of cotton woven fabrics comprising eleven weave structures and having a common count in the warp and weft and fabric sett was produced. Essential data such as the CFF, FYF, FFF, areal density, thickness and porosity were obtained. They were divided into four groups on the basis of their CFF and FFF, with each one designed to represent a particular effect. Air resistance was determined by performing the standard test KES- F8 – API. Analysis of the results shows a strong correlation between the CFF, FYF, FFF and air resistance. Fabrics which have long floats were characterized by lower air resistance, and the fabric which had no float displayed higher air resistance. The thickness is found to be well correlated with air resistance. Thus in addition to the CFF, FYF and FFF, the thickness should also be taken into consideration for predicting the air resistance of fabrics.
