Abstract

An anti-pilling processing method of protein-base fiber materials, which comprises contacting said protein-base fiber materials with a treating liquid at a pH ranging from 2.0 to 8.0, said treating liquid comprising a crosslinking agent selected from the groups consisting of a compound having both of a glycidyl group and a vinyl group, a compound having at least two glycidyl groups, a compound having at least two vinyl groups, and a glycidyl methacrylate compound as a crosslinking agent, wherein said protein-base fiber is crosslinked by said compound.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . An anti-pilling processing method of protein-base fiber materials, which comprises contacting said protein-base fiber materials with a treating liquid at a pH ranging from 2.0 to 8.0, said treating liquid comprising a crosslinking agent selected from the groups consisting of a compound having both of a glycidyl group and a vinyl group, a compound having at least two glycidyl groups, a compound having at least two vinyl groups, and a glycidyl methacrylate compound as a crosslinking agent, wherein said protein-base fiber is crosslinked by said compound.  
     
     
         2 . A pilling-resistant protein-base fiber material prepared by a method as defined in  claim 1.
