Factors affecting Air Permeability of 100% cotton single jersey fabric

Abstract

The aim of the study was to determine the effects of WPI, CPI, loop length, GSM, thickness of knitted fabrics on comfort parameters including air permeability. For this purpose, comfort properties of 100% cotton single jersey fabrics were determined. The air permeability of a fabric is defined as the amount of air passed over a surface under a certain pressure difference in a unit time. This value has significance with respect to the usage area. Since knitted fabrics have a loop structure, they have more pores than woven fabrics; therefore, in general, the air permeability of knitted fabrics is higher than that of woven fabrics of the same weight. It was found that knitted fabric of tighter structure has high weight and thickness but lower the value of air permeability. During our work we get some excellent test results which really help us to done our work perfectly.
