Title:
METHOD UTILIZING PROTEINASE K FOR ANTI-FELT FINISHING OF WOOL FABRIC
Document Type and Number:
WIPO Patent Application WO/2020/186950
Kind Code:
A1
Abstract:
The present invention relates to the applied technical field of wool fabric dyeing and finishing in the wool industry. Disclosed is a method utilizing proteinase K for anti-felt finishing of a wool fabric. The aim is to solve the problem of increased damages to wool strength and reduced keratin degradation effect in a scale layer brought forth by a common proteinase in an anti-felt treatment, thus achieving the goal of optimizing wool fabric protease anti-felt finishing. A preferred process is: urea peroxide is used first to pretreat a pure wool fabric, a chito-oligosaccharide is utilized to close CMC, and then proteinase K is utilized to treat the wool fabric. The wool fabric treated per the present method is provided with significantly improved anti-felt performance and damages to fabric strength are reduced. The present invention introduces proteinase K into wool anti-felt finishing for the first time, by means of the effective degradation of wool scale keratin via proteinase K, achieves improved wool anti-felt effects, and replaces a conventional chlorinated anti-felt treatment.
