Abstract:

The permeability properties are directly affected by fabric porosity. There are several methods which are theoretical and experimental to determine the porosity of textile materials. This study aims to determine the porosity of knitted fabrics with tuck stitches and plain knit fabric by using image analysis technique and geometry modeling and to reveal which technique is more suitable to determine fabric porosity in terms of air permeability. The study results proved that image analysis determining optical porosity are more suitable compared to geometry modeling since this method only focused on pore size. Besides, air permeability values are not parallel with the number of the tuck stitches unexpectedly since pore sizes change based on the location of tuck stitches in the knitted fabrics.
