Abstract
Disclosed is a water repellent for fibers, comprising an acryl-silicone graft copolymer which is prepared by a radical copolymerization reaction of an organopolysiloxane compound containing one radical polymerizable group with radical polymerizable monomers including an acrylate, a methacrylate or a mixture thereof as a main member.

A method for making fibers water repellent which comprises coating the fibers with a composition comprising an acryl-silicone copolymer prepared by the radical copolymerization reaction of an organopolysiloxane compound containing one radical polymerizable group with radical polymerizable monomers including an acrylate, a methacrylate or a mixture thereof as a main member, wherein the weight ratio of the organopolysiloxane compound to the radical polymerizable monomers is from 30:70 to 80:20.
A method for making fibers water repellent which comprises coating the fibers with a composition comprising:
- 0.5 to 20% by weight of an acryl-silicone copolymer prepared by the radical copolymerization reaction of an organopolysiloxane compound containing one radical polymerizable group with radical polymerizable monomers including an acrylate, a methacrylate or a mixture thereof as a main member;
- 30 to 98.5% by weight of an organic solvent;
- and 1 to 50% by weight of a jet gas.
