Anisotropy in Some Mechanical Properties of Woven Fabrics

A woven fabric is considered as an anisotropic lamina and initial modulus and crease recovery of cotton woven fabrics have been studied. It is observed that Patterson's relation of anisotropy in initial modulus for nonwoven fahrics is, also, generally valid for woven fabrics. Crease recovery in a bias direction is higher than those in the warp and weft directions. A marked difference exists in crease recovery values with twill woven fabrics for positive and negative direction of bending.
