Recently,it is found that cutinase has potential use in cotton bio-scouring and synthetic fibers modification.

Neutral scouring with KDN-T02 compound pectinase;

Application of bio-enzymes in scouring of cotton fabrics;

The writers expound the variety of enzyme, their characteristics and acting mechanism with focus on enzymatic degumming process of silk.

In order to recycle sericin efficiently from degumming water in silk mill,according to the characteristic of the degumming water and the properties of sericin protein,we researched the possibility of recycling sericin by freezemethod,determined the technical process of freezemethod,and found out its better technical parameters.

It is well-known that sericin is the main pollutant in degumming water of silk mill which is high and thick organic waste water.

Study on the Refining of Waste Silk Bisu Material with Ultrasonic and Conventional Method;

It ispointed out that refining is a key process to eliminate the difference ofcolour, and some measures are put forword.

Through comparing the ultrasonic refining effect with the traditional method for refining the waste silk frison material and studying on the feasibility of ultrasonic and the effect on the physicochemical property of the fiber,the reliable foundation was established that existing technique can be replaced by the ultrasonic method in the refining processes.
