Abstract
Abstract A composition containing (A) 10 parts by weight of an anionic product obtained by addition of 5 to 20 mols of ethylene oxide to an aliphatic saturated or unsaturated alcohol of 10 to 24 carbon atoms, followed by carboxymethylation (B) 1 to 15 parts by weight of a cationic addition product of 50 to 150 mols of ethylene oxide to a fatty amino-(C 2-3 )alkylene-amine (C) 1 to 10 parts by weight of a non-ionic addition product of 20 to 150 mols of ethylene oxide to castor oil, or a non-ionic sequenced addition product of 20 to 150 mols of ethylene oxide and 1 to 10 mols of propylene oxide to castor oil, and (D) 1 to 20 parts by weight of a N-(β-hydroxy-(C 2-4 )alkyl)-fatty acid amide, is a dyeing auxiliary useful for the dyeing in one bath or printing of a mixed textile substrate comprising cationic dyeable fibres and anionic or disperse dyeable fibres.
