A surfactant mixture comprises (a) 35 to 40 parts by weight of a monoalkylamide, dialkyl-amide, cycloalkylamide or alkylenamide of a monosulphonated and/or monosulphated unsaturated fatty acid having 14 to 22 carbon atoms, at least one of the alkyl or cycloalkyl radicals or the alkylene radical containing 4 to 12 carbon atoms and the chain of carbon atoms in said radicals being optionally interrupted by -O-or -NH-radicals, (b) 12 to 20 parts by weight of a monoalkylamide, dialkylamide, cycloalkylamide or alkylenamide of an unsaturated fatty acid having 14 to 22 carbon atoms, at least one of the alkyl or cycloalkyl radicals or the alkylene radical containing 4 to 12 carbon atoms and the chain of carbon atoms in said radicals being optionally interrupted by -O- or -NH- radicals, (c) 2 to 4 parts by weight of an unsaturated fatty acid having 14 to 22 carbon atoms or an alkali-metal or ammonium salt thereof, and (d) 0.05 to 2.5 parts by weight of a completely dissociating inorganic salt, e.g. sodium chloride or sodium sulphate.ALSO:A process for treating textiles comprises contacting them with a textile-treatment liquor containing a surfactant mixture comprising (a) 35 to 40 parts by weight of a monoalkylamide, dialkylamide, cycloalkylamide, or alkylenamide of a monosulphonated and/or monosulphated unsaturated fatty acid having 14 to 22 carbon atoms, at least one of the alkyl, or cycloalkyl radicals or the alkylene radical containing 4 to 12 carbon atoms and the chain of carbon atoms in said radicals being optionally interrupted by -O- or -NH- radicals, (b) 12 to 20 parts by weight of a monoalkylamide, dialkylamide, cycloalkylamide or alkylenamide of an unsaturated fatty acid having 14 to 22 carbon atoms, at least one of the alkyl or cycloalkyl radicals or the alkylene radical containing 4 to 12 carbon atoms and the chain of carbon atoms in these radicals being optionally interrupted by -O- or -NH- radicals (c) 2 to 4 parts by weight of an unsaturated fatty acid having 14 to 22 carbon atoms or an alkali-metal or ammonium salt thereof, and (d) 0.05 to 2.5 parts by weight of a completely dissociating inorganic salt, e.g. sodium chloride or sodium sulphate. Such liquors are useful as wetting agents for prewetting or reboiling skein yarn, wetting agents for bleaching without preboiling, dyeassistants for substantive dyeing of cotton, dyeassistants for dyeing cotton with sulphur dyes, wetting agents for vats containing levelling agents, wetting agents for bottoming liquors for dyeing cotton with developing dyes, wetting agents for dyeing union goods, and levelling agents in dyeing polyamide fibres with acid dyes. |
