Abstract
A method of fixing cellulose fibers dyed with a reactive dye, which comprises a homopolymer containing a vinylamine structural unit, a copolymer containing from 5 to 90% by weight of a vinylamine structural unit and from 5 to 90% by weight of a diallylamine structural unit, a copolymer containing from 5 to 90% by weight of a vinylamine structural unit, from 5 to 90% by weight of structural unit of a vinyl compound copolymerizable with the vinylamine, or copolymer containing from 5 to 90% by weight of a vinylamine structural unit, from 5 to 90% weight of a diallylamine structural unit and from 5 to 90% by weight of a structural unit of a vinyl compound copolymerizable with vinylamine and diallylamine, and/or a salt of the homopolymer or copolymers.
