Process for printing or dyeing cellulose-containing textile material: novel quaternary ammonium salt from sulpho-succinic acid mixed: di-ester for dye foam stability

摘要

Textile cellulose material is printed or dyed with reactive dyes with the aid of foam. The foam is applied by applying to the cellulose material a foamed, aqueous preparation which contains in addition to dyes and fixing alkalisPP(1) a foam-forming agentP P(2) a homopolymer or copolymer of acrylamide or methacrylamide or preferably a graft polymer which is obtained from an addition product of an alkylene oxide, preferably propylene oxide, on an at least trihydric aliphatic alcohol, e.g. glycerol, and acrylamide or methacrylamide, andPP(3) a betainelike quaternary ammonium salt which is obtainable by condensation of (A) a sulfonated asymmetric succinic acid diester which has as ester groups a halohydrin group and an etherified polyalkylene glycol group, with (B) a tertiary amine-substituted N- alkylamide of ethylenically unsaturated aliphatic monocarboxylic or dicarboxylic acid.PPThe cellulose material thus treated is then subjected to a heat treatment, for example steaming, to fix the dye.PPThis very stable preparation produces without the use of thickenings, in particular alginates, a strong, level and crisp print which at the same time has an excellent handle.
