Effect of various softeners on the performance of polyester-viscose ring and air-jet spun yarn fabrics

摘要

The effects of various softeners, viz. cellulase enzyme, caustic soda, a combination of cellulase enzyme and caustic soda, and non-ionic softener on the performance of twill fabrics made from polyester-viscose ring and air-jet spun yarns have been investigated in terms of flexural rigidity, tensile strength and crease recovery. The influence of pick density on the above properties has also been studied. It is observed that crease recovery and flexural rigidity improve considerably for the fabrics treated with cellulase enzyme followed by caustic soda, reasonably for the fabrics treated individually with the cellulase enzyme and caustic soda and marginally for the fabrics treated with non-ionic softener.
