Definitions

• the present invention concerns a process for the simultaneous dyeing or printing of textile fibre mixtures, especially in the form of carpets or furniture covering material, in which at least one type of fibre has aflinity to cationic dyestuff and at least one other type of fibre has afiinity to anionic dyestutf, as well as the textile fibre mixtures dyed or printed using the process according to the invention.
• the single-bath dyeing or printing of textile material consisting of fibre mixtures of differing dyestulf afiinity, renders necessary the selection of specific dyestuffs for each type of fibre.
• the selection to be made frequently represents a compromise with respect to the evenness and fastness of the dyeings therewith obtainable, to the stability of the liquor and to other properties, since the ideal dyestuff for one type of fibre is often completely unsuitable for another type.
• Typical fibre mixtures, the dyeing of which presents such difficulties consist, for example, of polyacrylonitrile and synthetic polyamide fibres or of polyacrylonitrile and cotton fibres.
• textile fibre mixtures of the above mentioned type can be very evenly dyed or printed, in one shade or in several shades, with satisfactory fastness properties and without the effect known as the sandwich effect, by impregnating or printing the fibre mixture at temperatures below the absorption temperature of the dyestuffs using an optionally thickened solution which contains at least one cationic dyestuif and at least one anionic dyestuff, sufficient acid and buffer salt for the purpose of maintaining a pH-value of the solution between 3 and 7, at least 0.5 g./litre of sulphated or sulphonated compound as anion-active auxiliary and at least 0.5 g./
• Suitable sulphated or sulphonated compounds are, e.g.:
• sulphated primary or secondary alkanols or alkenols the alkyl chain of which contains from 8 to 20 carbon atoms, e.g. sodium lauryl sulphate, sodium-a-methyl stearyl sulphate, ammonium tridecyl sulphate, sodium oleyl sulphate, potassium steanyl sulphate or the sodium salts of the coconut oil fatty alcohol sulphates;
• sulphated unsaturated higher fatty acids or fatty acid esters such as oleic acid, elaidic acid or ricinoleic acid, or their lower alkyl esters, e.g. ethyl, propyl or butyl esters, and the oils containing such fatty acids, such as olive oil, castor oil, rape oil, etc.;
• sulphated polyglycol ethers such as sulphated addition products of from 1 to 20 moles of ethylene oxide with fatty' acid alkanolamides, mercaptans, amines or fatty acids, particularly, however, with aliphatic alcohols or alkylphenols having from 8 to 20 carbon atoms in the alkyl chain, e.g. with lauric acid-B-hydroxyethylamide, decylmercaptan, stearylamine, stearic acid, oleic acid, lauryl alcohol, myristyl alcohol, stearyl alcohol, oleyl alcohol, octyl phenol or nonyl phenol;
• alkanolamides e.g. the sulphated amides of caprylic, pelargonic, capric, lauric, myristic or stearic acid, or of lower fatty acids substituted by alkylphenoxyigroups, such as octylor nonylphenoxyacetic acid, with monoor bis-hydroxyalklamines such as ,3- hydroxyethylarnine, vhydroxypropylamine, 3,y-dihy-- droxypropylfirliine, bis- (B-hydroxyethyDamine, or with N- alkyl-N-hydrpxyalkylamines such as N-methylor N- ethyl-N-(B-hydroxyethyl)-amine;
• alkylphenoxyigroups such as octylor nonylphenoxyacetic acid
• sulphated esterified polyoxy compounds e.g. sulphated, partially esterified polyols such as the sodium salt of the sulphated monoglyceride of palmitic acid;
• primary and secondary alkyl sulphonates of which the alkyl chain contains from 10 to 20 carbon atoms, e.g. ammonium dodecyl sulphonate, sodium hexadecane sulphonate-8, sodium stearyl sulphonate;
• alkylaryl sulphonates such as alkylbenzene sulphonates with a straight-chained or branched alkyl chain having at least 7 carbon atoms, e.g. sodium dodecylbenzene sulphonate, l,3,5,7-tetramethyl-octylbenzene sulphonate, sodium octadecylbenzene sulphonate, or such as alkylnaphthalene sulphonates, e.g.
• sodium-l-isopropylnaphthalene-Z-sulphonate sodium dibutylnaphthalene sulphonate; or dinaphthylmethane sulphonates, e.g. the disodium salt of the di-(6-sulphonaphthyl-2)-methane;
• sulphonates of polycarboxylic acid esters e.g. potassium dioctylsulphosuccinate, sodium dihexylsulphophthalate.
• alkylaryl sulphonates are used, especially dinaphthylmethane sulphonates, or sulphated polyglycol ethers, particularly sulphated polyglycol ethers of aliphatic alcohols or alkylphenos containing from 8 to 20 carbon atoms in the alkyl chain, said polyglycol ethers having from 1 to 20 ethyleneoxy groups and, most particularly, sulphated lauryl alcohol polyglycol ethers having from 2 to 3 ethyleneoxy groups, or sulphated polyglycol ethers of octyl or nonyl phenol having from 2 to 3 ethyleneoxy groups.

• amides are obtained by methods known per se by reacting the esters of monocarboxylic acids, as defined, with lower alkanols, e.g. by reacting the fatty acid methyl or -ethyl esters with the desired amine in the presence of sodium or potassium alcoholates, e.g. using a process described in the British Pat. 631,637.
• condensation products from 1 equivalent of fatty acids having from 8 to 20 carbon atoms, or from mixtures of such fatty acids with from 1 to 3 equivalents of a diand/or trialkanolamine.
• These condensation products can be produced by the process described in U.S.A. Pat. 2,089,212, by heating the fatty acids with from 1-3 equivalents of diand/or trialkanolamines, especially diethanolamine, while splitting off more than 1 mole of water.
• anion-active auxiliaries and amides or condensation products can vary within wide limits and they depend both on the type and amount of the dyestutfs used and on the choice and composition of the substrate. They can each be used in amounts of up to 50 g./litre of dye liquor or printing paste.
