ABSTRACT:
An improved process for dyeing of diverse fibre material, especially textile fibres, by applying to the fibre material at a temperature below the absorption temperature of the dyestuffs a concentrated aqueous dye liquor and with a goods to liquor ratio of 1:1.5 to 1:4, the said aqueous dye liquor containing at least one dyestuff which, in the case of the substrate to be dyed, has affinity to the fibres and which is either soluble or dispersible in water and 0.2 to 10 g/l, preferably 2 to 5 g/l, of a non-foaming anionic dispersing agent from the class of aromatic sulphonic acids or the water-soluble salts thereof, and finishing of the dyeing by means of a heat treatment, e.g. introduction of saturated steam, superheated steam or hot air, preferably by heating from without, at temperatures of 95.degree. to 140.degree. C.
