• R 1 and R 2 the methyl, ethyl, n-propyl, iso-propyl, n-butyl and sec.-butyl radicals may be mentioned as C 1 -C 4 alkyl radicals.
• R is C 1 -C 4 alkyl or cyclohexyl and R 1 and R 2 are hydrogen or methyl.
• the average molecular weight of the polyethers to be used according to the invention should be between 500 and 20,000, preferably 1,000 to 15,000.
• the polyethers to be used according to the invention are linear or slightly branched polyethers.
• the linear polyethers can be prepared by known methods by condensing N-2-hydroxyalkylamines of the formula I in the presence of acidic catalysts, for example H 3 PO 3 high temperatures, for example 150 - 280 ° C can be obtained.
• acidic catalysts for example H 3 PO 3 high temperatures, for example 150 - 280 ° C can be obtained.
• the diols containing tertiary amino groups are condensed together with triols containing tertiary amino groups, ie N-2-hydroxyalkylamines of the formula I in which R represents one of the stated B-hydroxyalkyl groups.
• the amount of triols in the condensation mixture should not be more than 20 percent by weight, preferably 2-15 percent by weight.
• polyethers to be used according to the invention are known, for example, from GB-A-1 107 818 and DE-A-2 060 572.
• B-Hydroxyalkylamines of the formula (I) which may be mentioned are, for example, the N-di- (2-hydroxyalkyl) amines as used in the addition of ethylene, propylene and butylene oxide or mixtures of these alkylene oxides to primary aliphatic, cycloaliphatic, araliphatic and aromatic amines are formed.
• Triethanolamine, triisopropanolamine and tributanolamine may be mentioned in particular as representatives of the triols used to prepare the branched polyethers.
• the quaternization is carried out in a manner known per se by reacting the polyethers which are optionally dissolved or suspended in alcohol / water mixtures with known alkylating agents, such as dimethyl sulfate or diethyl sulfate; p-toluenesulfonic acid alkyl esters, e.g. p-toluenesulfonic acid methyl ester; Alkyl halides, e.g.
• Methyl iodide or ethyl bromide Chloroacetamide, halocarboxylic acid salts, halocarboxylic acid esters, alkane sultones, benzyl chloride, methanephosphonic acid dimethyl ester, trimethyl phosphate or alkylene oxide such as ethylene oxide and propylene oxide in the presence of acids.
• the amounts in which the quaternized polyethers to be used according to the invention are added to the aqueous liquors can fluctuate within wide limits. In general, an addition of 0.1-2%, preferably 0.2-1%, based on the weight of the fiber materials, has proven useful.
• the quaternized polyethers can be applied in a pretreatment process to the untreated fiber material to be dyed or printed in order to improve the color yield by impregnating or printing with aqueous liquors which contain the quaternized polyethers.
• the fiber material treated in this way is e.g. squeezed to a liquor intake of 60-100%, dried and, if necessary after heat treatment, e.g. by brief steaming at 102 - 120 °, colored or printed in the usual way.
• the aftertreatment of the dyed or printed fiber material to improve the wet fastness is carried out either in the exhaust process, e.g. for 20-30 minutes into an aqueous liquor which contains the quaternized polyethers to be used according to the invention and has a pH of e.g. 4-8, preferably 5.5-6.5, and a temperature of 20-40 ° C, or the liquor used for after-treatment continuously, e.g. by means of a foulard onto which colored or printed material is applied.
• Suitable dyes for producing the dyeings and prints are, for example, in the Color Index, 3rd edition (1971), Vol. 2 listed on pages 2005-2478 as direct dyes and on pages 1001-1562 as acid dyes.
• Suitable reactive dyes are described, for example, in Venkataraman, The Chemistry of Synthetic Dyes, Volume VI, Reactive Dyes (Academic Press, New York, London 1972).
• Fiber materials suitable according to the invention are, above all, those made from natural or regenerated cellulose; Cotton, hemp, jute, linen, as well as viscose and cellulose acetate fibers and blended fabrics containing cellulose fibers are mentioned.
• the fiber material can be in various processing states and e.g. exist as loose material, yarn, woven or knitted fabric.
• the color yield and the fastness properties of dyeings and prints are considerably improved.
• the compounds according to the invention offer the advantage of being completely free from formaldehyde.
• Another advantage of the claimed compounds is the slight impairment in the grip of the treated ones Fiber materials and the lightfastness of the dyeings. Furthermore, they do not cause color changes in the colorings.
• Polyether B was produced analogously to polyether A, except that instead of the 82 parts of dimethyl sulfate, only 54 parts of dimethyl sulfate (0.5 mol of dimethyl sulfate per mole of basic amino group) were used for the quaternization. The Q remains uatern réelles. back as a yellow water-soluble syrup.
• Polyether C was prepared analogously to polyether A, except that 108 parts of dimethyl sulfate (1.0 mol of dimethyl sulfate per mol of basic amino group) were used instead of the 82 parts of dimethyl sulfate for the quaternization.
• the quaternization product remains as a yellow water-soluble syrup.
