Proprieties of Plain-Weave Fabrics Produced with Twistless Cotton Yarns Made by Reverse Twist Process

Abstract

Properties, viz. mechanical performances, air permeability, water vapour diffusion, and wicking height of absorbed water in fabrics above level of water, of plain-weave fabrics woven by twistless yarns and equivalent conventional ring spun yarns have been investigated in this paper. The experimental twistless yarns were made by reverse twisting process which spun the yarns on the ring frame and removed the twist of said yarns by reverse twist process. The results show that a fabric produced by yarns which have twists are considerably stronger than the twistless fabric in both breaking strength and tearing strength, air permeability of the twistless fabric is approximately 23.74% lower than its corresponding fabric made by conventional ring spun yarns. However, compared to the fabric made by conventional ring spun yarns, twistless fabric fares well in water vapour diffusion and wickability.
