Document Type and Number:
WIPO Patent Application WO/2024/034530
Kind Code:
A1
Abstract:
This fiber treatment agent contains (A) 100 parts by mass of an organohydrogen polysiloxane represented by an average composition formula (1), (B) 5-100 parts by mass of a silicone-acryl copolymer resin which is a copolymerization product between (b1) 40-99 mass% of an organopolysiloxane represented by average composition formula (2) and (b2) 1-60 mass% of a (meth)acrylic acid ester monomer (the total of components (b1) and (b2) being 100 mass%), (C) 0.5-50 parts by mass of a surfactant, (D) 5-100 parts by mass of a condensation reaction catalyst, and (E) 50-3,000 parts by mass of water. The fiber treatment agent has excellent water repellency providing effect, and can provide excellent flexibility and texture to fibers after being treated.
