A Generalized Model for Predicting Load-Extension Properties of Woven Fabrics

Abstract

A method to predict the load-extension behavior of woven fabrics is proposed. Kawabata et al.'s finite deformation theory, which predicts load-extension properties of plain weave and 2/2 twill fabrics in terms of fabric construction parameters and yarn tensile properties, is the basis for the study. The model is generalized to predict the load-elongation behavior of any weave by introducing a parameter that characterizes the interlacing point distribution pattern of the weave. Using the biaxial and uniaxial strain modes, the load-deformation curves over an entire range of strains can be generated. The model applies to woven structures of different degrees of openness, of which the fabric jamming condition is an extreme case.
