Process for dyeing cellulose-containing fibre materials by the cold pad-batch or pad-steam method: maleic anhydride-styrene copolymer

摘要

The dyeing of cellulose fibres or fibre blends containing cellulose fibres with reactive dyes by a cold pad-batch or pad-steam process is effected with aqueous padding liquors which contain water-soluble reaction products of copolymers of maleic anhydride and ethylene, propylene, isobutylene, diisobutylene or styrene with ammonia or amines of the formula I in which R1 and R2 stand for hydrogen, C1-C4-alkyl or C1-C4-hydroxyalkyl.
