Abstract
1368129 Dyeing' cellulose with azoic dyes FARBWERKE HOEGHST AG 19 Nov 1971 [20 Nov 1970] 53835/71 Heading D1B Sliver or yarn of cellulose fibres are dyed in the form of a wound package by impregnating the package with an aqueous alkaline liquor comprising an alkaline substance and one or more azo coupling components followed by injecting into the package one or more weakly acidic solutions each comprising at least two diazonium compounds of different diffusibility and each derived from an aromatic amine. The preferred alkali is sodium hydroxide, the coupling components being arylamides of aromatic or heterocyclic ohydroxy carboxylic acids, or of an acylacetic acid, or an aromatic or heterocyclic hydroxy compound or a compound containing an enolizable or enolized ketomethylene group in a heterocyclic ring. The impregnation may be effected at 20 to 60C in presence of non- ionic or anionic wetting agents, optionally the package may be further injected with a weakly acidic solution of a single diazonium componet, and then allowed to dwell for up to 5 minutes.
