Effect of twist factor on middle and high tex cotton yarn’s strength and elongation
Abstract:Yarn strength and elongation have direct relationship with the twist factor. The critical twist factor distribution is of great importance in selecting twist factor. In this paper, the strength and elongation of CJ18.2tex yarn and CJ14.6tex yarn spun with different twist factors were studied. The result shows that the critical twist factor of CJ18.2tex yarn is 500 appropriately and the critical twist factor of CJ14.6tex yarn is 460 appropriately. They own their best strength when spun by using critical twist factors.
