    摘要： Disclosed is a process for dyeing or printing a voluminous textile substrate comprising natural or synthetic polyamide fibres, which process comprises applying to the substrate an aqueous dyeing or printing medium containing 0.05 to 100 g/l of a foaming agent, forming a foam on said substrate, rolling up the substrate and rotating the rolled up substrate for a period of from 1 to 48 hours at a temperature of from 20.degree. to 60.degree.C to effect fixation.

    摘要： The invention relates to a process for dyeing synthetic or natural polyamide fibers with anionic dyestuffs, comprising (i) bringing the polyamide fibers into contact with an aqueous dyeing liquor which contains in addition to one or more dyestuffs a cationic dyeing assistant having affinity for anionic polyamide dyestuffs, and dyeing the polyamide fibers at a temperature of from 60.degree. to 105.degree. C., and (ii) adding an anionic dyeing assistant to the dyeing liquor 15 to 60 minutes after reaching the dyeing temperature, to complete the dye exhaustion. Surface and fibre level dyeings with a good dye penetration are thus obtained.

    摘要： The invention provides a process for dyeing a textile substrate comprising wool fibres, which process comprises bringing the substrate into contact with an aqueous dyebath containing an acid dyestuff or a mixture of acid dyestuffs having(a) a build-up power on wool of from 90 to 98% at pH 4.5; together with(b) a migrating ability on wool of from 25 to 40%, at pH 4.5;(a) and (b) being determined under specific conditions, in the presence of a levelling agent which is the alkoxylation product of an amine substituted by a fatty saturated or unsaturated residue, the aqueous dyebath containing a mixture of acid dyestuffs when the substrate is a wool/synthetic polyamide fibre blend.These dyestuffs give level, fast and reproducible dyeings of a high quality.
