Changes in anisotropy (strength and initial modulus) of fabric have also been studied. It is observed that the values of above-mentioned properties along any direction of fabric are dependent on the degree of fibre inclination in that particular direction. Fabrics made from card sliver web show considerably lower anisotropy than those made from drawing sliver web.</span>
