• textured polyamide fibre material e.g. Banlon
• aqueous solution of a mixture of auxiliaries consisting of (a) at least one anion-active compound of Formula I,
• R represents an alkyl radical having from 8 to 18 carbon atoms
• X represents a cation and n represents a number from 1 to 2
• Anion-active compounds of Formula I are known per se and can be produced, e.g. by the methods described in British Pats. Nos. 912,340 and 1,043,043, by reacting correspondingly substituted diphenyl ethers together with a sulphonating agent, such as sulphur trioxide or chlorosulphonic acid, in the solution of a poly-chlorinated aliphatic hydrocarbon, or by dissolving the diphenyl ether compound in a saturated aliphatic hydrocarbon and then bringing it into contact with the sulphonating agent.
• a sulphonating agent such as sulphur trioxide or chlorosulphonic acid
• Anion-active compounds of Formula I which have proved particularly valuable, in the process according to the invention, are those wherein R represents an alkyl radical having from 9 to 12 carbon atoms, X represents an alkali metal ion, such as the lithium or potassium ion, preferably, however, the sodium ion, or the ammonium ion and n represents the number 2.
• Disulphonated compounds of Formula I which are obtained by sulphonating the 4-dodecyldiphenyl ether, are especially preferred.
• the cation-active, non-quaternated or quaternated compounds (b), usable in the process according to the invention, are likewise known per se and can be produced in a manner known per se, e.g. by reaction of the corresponding aliphatic amines, especially long-chain primary alkylmono-, -dior -tri-arnines, the alkyl or alkenyl radical of which contains from 10 to 18 carbon atoms, such as dodecyl-, octadecylor octadecenylamine, dodecylpropylenediamine, octadecylethylenediamine and octadecyldiethylenetriamine, with alkylene oxides, e.g.
• Suitable cationactive compounds (b), usable according to the invention are also products obtained by reaction of the above mentioned alkylamines with from 1 to 2 equivalents of styrene oxide, from 0 to 2 equivalents of propylene oxide and from 1 to 19 equivalents of ethylene oxide as well as, optionally, subsequent quaternisation.

These can be, for example, the commercially important dyestulf classes of the azo, anthraquinone, phthalocyanine, nitro or formazane dyestuffs which can also contain metals bound in complex linkage such as copper, nickel, chromium or cobalt. Suitable azo dyestuffs are, principally, monoazo dyestuffs, e.g.
• the 2120 dyestuffs to which also belong the formazane dyestutfs, can be metallised, principally by chromium or cobalt, but also by cop per or nickel, whereby 1 or 2 dyestufi molecules per metal ion participate in the complex.
• the pH-value of the dye bath is adjusted to the desired value by the addition of an acid, such as acetic acid, formic acid or sulphuric acid.
• the weight ratio of anion-active to cation-active compound is thereby advantageously from 1:1 to :1.
• the acidity of the dye liquor can be reduced by the addition of an acid-binding agent, such as an alkali metal hydroxide, -carbonate or -hydrogen carbonate, by the addition of ammonium hydroxide, disodium or dipotassium phosphate, sodium or potassium acetate, as well as by the addition of hexamethylenetetramine.
• an acid-binding agent such as an alkali metal hydroxide, -carbonate or -hydrogen carbonate
• An advantageous embodiment of the process, according to the invention consists in carrying out the preliminary treatment at boiling temperature, then adding the predissolved dyestufi and completing the dyeing at the same temperature. After the dyeing is completed, the dyed material is advantageously rinsed in the usual manner, if necessary given an aftertreatment to improve the fastness to wet processing, and dried.
