Abstract: Bio-enzymes are widely used for textile processing in recent years due to their characteristics such as high efficiency,high specificity and mild processing condition as well as eco-friendly.The scouring effects of some enzymes including pectinase,cellulase,protease and their mixtures were investigated by researchers throughout the world.This paper introduced and evaluated the bioscouring effect of various enzymes since the emergence of enzymatic scouring so as to reveal the advances in this field roundly and provide beneficial references for production and application of enzymes for cotton scouring.
