ABSTRACT:
An improved process for dyeing of fibre material, especially textile fibres, by applying to the fibre material at a temperature below the absorption temperature of the dyestuffs and with a goods-to-liquor ratio of 1:1.5 to 1:4, a concentrated aqueous dye liquor, said concentrated 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 at least one nonionic, surface-active agent from the class of ethylene oxide addition products and having a cloud point below 85.degree. C., 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.
