Abstract

Shear is one of the most important mechanical behaviours which differentiates a woven fabric from papers and polymeric sheets. In this work a generalised mathematical model of shear rigidity of woven fabric applicable to all types of weaves has been proposed. The model demonstrates the shear rigidity of woven fabric as a function of yarn bending rigidity, fabric structural parameters and crossover firmness factor. Experimental shear rigidity results are compared with the theoretically predicted ones and a very good agreement is reached. The proposed mathematical model can able predict the shear rigidity of any woven fabric structure and thus foretells the usefulness of the fabric for a particular use.
