METHOD FOR PRODUCING ANTI-SHRINKAGE ANIMAL HAIR FIBERS

Document Type and Number:

WIPO Patent Application WO/2021/014620

Kind Code:

A1

Abstract:

Provided is a method for efficiently producing anti-shrinkage animal hair fibers having sufficiently high water-resistant launderability in a sliver form while maintaining inherent water repellency as one of features of animal hair fibers without deteriorating the texture and other features. The method for producing anti-shrinkage animal hair fibers is characterized in that a sliver, which is a continuous body of animal hair fibers, is immersed in a diamine aqueous solution containing an alkaline agent at 30-45°C, and immersed in a silicon solvent with a dibasic acid chloride dissolved therein in a state in which the diamine is attached to the sliver, thereby coating the animal hair fibers with a polyamide.
