摘要

Enzymatic hydrolysis on polyester fabrics enhances the hydrophitlicity and solves the concerns regarding the environmental issues. Lipase hydrolyses ester linkages in Polyethylene Terephthalate (PET) and produces polar hydroxyl and carboxylic groups. This study aims to know the effect of enzyme treatment on the weight loss of polyester fabrics. This work investigates the effect of enzyme treatment on the surface modification of the fabrics the functional groups presence after treatments and the improvement of dye uptake are studied. The test results shows that enzymatic process creates less surface damage, weight loss and improved moisture regain, dye uptake and shear properties.
