摘要：1. A process for the uniform tone-in-tone dyeing of textile woven or knit fabricsmade from mixtures of cellulose fibres and synthetic polyamide fibres according to acontinuous or semi-continuous method of the pad-dyeing technique from a single bathwith water-insoluble azo dyestuffs formed on the fibre from coupling component anddiazo component in the form of a stabilized diazonium compound, in which the dyestuffcomponents are mutually applied under alkaline conditions and dyestuff development iscaused by the action of acid, which process comprises using as the diazo component awate-soluble diazoamino compound obtained from a diazotized, aromatic or heterocyclicamine and cyanamide, padding the textile goods at temperatures ranging of from 60degrees to 70 degrees C with an aqueous, alcoholic liquor containing both of dyestuffcomponents in dissolved form, and wherein - immediately after the padding operationbut before effecting the acid treatment, which is necessary for liberating the diazoniumcompound and coupling - the said impregnated textile goods are steamed without
intermediate drying.
