Abstract

1377210 Dyeing cellulose with azoic dyes FARBWERKE HOECHST AG 10 Dec 1971 [12 Dec 1970] 57466/71 Heading D1B Cellulose fibres and cellulose textile materials are dyed by applying a diazo component and a coupling component from aqueous solution or solutions followed by treating with an organic liquids which contain at most 6% of water calculated on the weight of the organic liquids to finish the dyeing. Diazoamino and anti-diazotate compounds may be used for the dyeing process, which is preferably a continuous process. Trichloroethylene, perchloroethylene, tetrachloroethane, methylene chloride, benzene trifluorotrichloroethane, xylene and tetraline are used as organic liquids. Preferably the coupling component is applied in alkaline solution followed by drying and passing the material through an aqueous solution of diazo component containing acetic, formic or propionic acid.
