Abstract
An assistant for dyeing or whitening synthetic nitrogen-containing fibre material, which comprises (A) a sulfonated polycarboxylate, (B) an anionic surfactant, (C) a nonionic surfactant, and (D) a water-soluble organic, polar solvent. The assistant is especially useful for dyeing or whitening polyamide fibres.
Claims10
A dyeing assistant for dyeing or whitening synthetic nitrogen-containing fibre materials, which assistant comprises
- (A) 10 to 30% by weight of a bisalkyl sulfosuccinate or sulfosuccinamide,
- (B) 25 to 50% by weight of an anionic surfactant,
- (C) 5 to 20% by weight of an amine oxide of the formula ##STR10## wherein R is C.sub.8 -C.sub.22 alkyl and R.sub.1 is C.sub.1 -C.sub.4 alkyl,
- (D) 5 to 20% by weight of a water-soluble organic polar solvent selected from the group consisting of an aliphatic C.sub.1 -C.sub.6 -alcohol, an alkylene glycol, a monoalkyl ether of a glycol, a ketone, an ether, an acetal, pyridine, acetonitrile, .gamma.-butyrolactone, N,N-dimethylformamide, N,N-dimethylacetamide, tetramethylurea and tetramethylene sulfone, and
- 0to 55% by weight of water.
