Abstract

1512914 Dyeing natural or synthetic polyamides BAYER AG 14 Sept 1976 [20 Sept 1975] 38009/76 Heading D1B Natural or synthetic polyamide fibres are dved by an afterchroming process in which after the dye has been taken up a chroming agent is applied in the molar ratio dyestuff : chromium of 2:1 to 1:2 and a water-soluble acid and/or its salt wherein the acid and/or salt anion contains phosphorus, sulphur and/or chlorine and is free from chromophoric groups. The water-soluble salt may be an alkali metal salt of sulphuric acid, an alkyl-sulphonic acid, an arylsulphonic acid or an alkylsulphuric acid, or of an addition product thereof with an alkylene oxide. The substrates may be treated in either sequence with the chroming agent and water-soluble salt or both are applied together.
