摘要： The disclosure discloses a method for anti-felting finishing of wool fabric with protease K, and belongs to the technical field of dyeing and finishing of wool fabric in the wool spinning industry. The purpose is to solve the problems that common protease anti-felting treatment has greater damage to the strength of wool and has a weak degradation effect on keratin in a scale layer, thereby achieving the purpose of optimizing the anti-felting finishing of wool fabrics with protease. A preferred process is: pure wool fabric is first pretreated with urea peroxide, CMC is blocked with chitosan oligosaccharides, and then the wool fabric is treated with protease K. The wool fabric treated by the method has obviously improved anti-felting property, and the damage to the strength of the fabric is reduced. The disclosure introduces protease K into the anti-felting finishing of wool for the first time. Through effective degradation of keratin in wool scales by the protease K, a good anti-felting effect of wool is achieved, and the protease K anti-felting treatment can replace the traditional chlorination anti-felting treatment.
