Abstract: The invention relates to a process for the production of anti-shrink treated wool dyeings in which wool is dyed with acid milling or metal complex dyes either before, after or between the steps of an anti-shrink treatment and, after the dyeing or the anti-shrink treatment or one of the steps of the anti-shrink treatment subsequent to the dyeing, is after-treated with a liquor containing a cationic fixing agent and a levelling/retarding agent having affinity for wool dyestuffs, and to a composition usable for such a process.

Abstract: The invention relates to a wet-on-wet dyeing process comprising(A) impregnating the substrate with an acid dyeing liquor containing an anionic dye having a K'.sub.pH6 -value.gtoreq.5(B) applying locally to the substrate at room temperature, a liquor or paste containing an alkoxylated fatty amine or polyamine having affinity for anionic dyes with a K'.sub.pH6 -value.gtoreq.5, said step (B) being carried out directly after or directly before said step (A), and(C) subsequently submitting the substrate to a heat treatment to effect fixation of the dye.

Abstract: The present invention provides a process for dyeing an anionic dyeable substrate with reserve and/or multicolored effects, which process comprises(1) impregnating the substrate with a dyeing liquor containing an anionic dye having a K'-value.gtoreq.5(2) directly thereafter applying locally to the substrate a liquor or paste containing an alkoxylated fatty amine or polyamine having affinity for anionic dyes with a K'value.gtoreq.5 and optionally a disperse dye and/or an anionic dye or an anionic optical brightening agent with the proviso that the anionic dye or optical brightening agent has a K-value at least one unit lower than the K'value of the anionic dye used in step (1), and(3) subsequently submitting the substrate to a heat treatment to effect fixation of the dye(s) and, if used, optical brightening agent.
