Investigation of Air Permeability of Cotton & Modal Knitted Fabrics

In this study, it was aimed to investigate the porosity / compactness of the knitted structures made from cotton and modal yarns and to evaluate the air permeability property for sportswear. In the experimental section, cotton and modal yarns spun in different counts ( Ne 30, Ne 40 ) with the same twist coefficient of αe = 3.53 and 3.3 respectively were knitted as single jersey fabrics in the same production conditions with four tightness factors and air permeabililty property of fabrics were measured. The result showed that air permeability is a function of the thickness, tightness factor and porosity of the knitted fabrics and modal single jersey fabrics are considered preferred candidates for warmer climate sportswear, due to their higher air permeability.
