摘要:
Process for dichromatic or trichromatic dyeing or printing of natural or synthetic polyamide fibre material, which comprises using at least one blue-dyeing fibre-reactive anthraquinone dye of the formula ##STR1## in which R.sub.1 and R.sub.2 independently of one another are hydrogen or substituted or unsubstituted C.sub.1 -C.sub.12 alkyl, X.sub.1 is halogen, B.sub.1 is an organic bridge member and V.sub.1 is an aliphatic or aromatic amine containing a fibre-reactive group, together with at least one fibre-reactive sulfo group containing yellow- or orange-dyeing dye or together with at least one fibre-reactive sulfo group containing red-dyeing dye. Level dyeings with good fastness properties are obtained.
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.
