Abstract

The study reported in this paper concerns the influence of both polyester ratio and twist multiplier of weft yarns on the fabric tensile properties, specially, specific work of rupture, extensibility and tear strength. Mathematical models describing these parameters in both the warp and weft directions are presented in a form that can be easily predicted. It was found that the optimum values of polyester percent and twist multiplier of the weft yarns for obtaining the highest possible fabric strength in warp direction were 67% and 3.45 αe while in the weft direction were 67% and 3.8 αe
