Mixture of assistants and its use in the dyeing of synthetic fibre materials: acid ester of oxyalkylated phendl, nonionic surfactant and dye carrier

摘要

Mixture of dyeing assistants containing (A) an acid ester, or salts thereof, of an alkylene oxide adduct of the formula (1) in which V is hydrogen or methyl, X is the acid radical of an inorganic acid containing oxygen, or the radical of an organic acid and Y is C1-C12alkyl, aryl or aralkyl, "alkylene" is the ethylene or propylene radical and m is 1 to 3, m1 is 1 or 2 and n is 4 to 50, (B) a nonionic surfactant containing polyglycol ether groups, and (C) an aliphatic or aromatic carboxylic acid ester, an alkylbenzene, tetralin or a mixture of these substances. The mixture of assistants is employed in the dyeing of synthetic fibre materials, in particular textile material containing polyester fibres, for increasing the rate of migration of disperse dyes.
