Title:
METHOD OF SHRINK-PROOFING ANIMAL HAIR FIBER
Document Type and Number:
WIPO Patent Application WO/2004/070106
Kind Code:
A1
Abstract:
It is intended to provide a method of shrink-proofing an animal hair fiber characterized by comprising subjecting the animal hair fiber to a pulse corona processing or an oxidation treatment with the use of a chlorine-free oxidizing agent, and then enzymatically treating it with an alkali protease which has an activity of digesting keratin of 70 AKU or higher, a ratio of a collagen digestion activity to the keratin digestion activity of 2 or smaller, and a ratio of an elastin digestion activity to the keratin digestion activity of 4 or smaller. According to this method, a highly shrink-proofing animal hair fiber can be obtained.
