Dyeing or finishing process using padding with continuous fixing of textile materials: graft polymer and microwave heating

摘要

Dyeing or finishing process characterized in that textile materials are impregnated in a padding machine with aqueous dyeing or finishing baths which contain, besides graft polymers, which may be obtained from a product of addition of an alkylene oxide to an at least trivalent aliphatic alcohol containing from 3 to 10 carbon atoms and methacrylamide or acrylamide, and in that the fixing of the dyes or of the finish is then performed continuously by a treatment with microwaves for 5 to 30 seconds. The process permits an excess water input on all the textile materials and a rapid fixing by the microwaves.
