Because of specificity and high efficiency, the catalytic efficiency of cellulase is high(more 103~1013 times than general catalysts), the condition of catalytic reaction is mild and the catalytic activation can be adjusted and controlled, which can improve remarkably semblance and handle of fabrics during finishing fabrics by biological catalyzing, moreover cellulase can replace some chemical materials such as acid, cocain, chlorine and phosphorus etc, so as to decrease pollution, make no waste-water and protect environment.

由于酶具有专一性和高效性，采用生物催化，其催化效率高比一般催化剂高10~3～10~(13倍，催化反应条件温和，催化活性可调节控制，应用在纺织品处理上，能显著改善织物的外观和手感，并能取代一部分酸、碱、氯、磷化合物等化工原料，从而减少污染，不产生污水，有利于环保和生态。而且酶本身又无毒，容易生物降解，不会引起环境污染，所以酶处理已被公认为是一种符合环保要求的绿色印染加工方法。本文选用了市场上常用的纤维素酶R-10和纤维素酶ECS2610两种生物酶。
