Definitions

• the required amounts of the cation-active compounds can readily be established during preliminary experiments; amounts of 0.1%, referred to the dry weight of the textiles to be treated, are in general already found to be suflicient.
• the compounds to be employed according to the invention are distinguished by an unexpectedly more intensive activity compared with the fatty acid esters and fatty acid amides mentioned above, particularly with regard to an improvement in the feel of the textiles.
• EXAMPLE 1 3 kg. of a textile fabric (towelling) consisting of cotton which had been washed and rinsed about 20 times in an automatic drum washing machine with a commercial detergent based on dodecyl-benzene sulphonate, and which had become stiff and hard after drying, are treated with the cation-active compound of the formula R is an alkyl radical of 1-4 carbon atoms; and n is an by adding 3 g. of this compound, in the form of its 7.5%
• the cation-active compounds which can be suitably employed according to the invention may for instance be obtained by heating 1 mole of the compound of the formula with 1 mole of the compound of the formula R -COOH and 1 mole of the formula R COOH at 180 to 190 C. for several hours; in these formulae the symbols R R R and R, as well as X and n have the significance mentioned above.
• the cation-active compounds are conveniently employed in the form of their salts with lower organic acids or with inorganic acids, such as formic acid and acetic acid or hydrochloric acid and phosphoric acid.
• inorganic acids such as formic acid and acetic acid or hydrochloric acid and phosphoric acid.
• aqueous emulsion which also contains 3.8% acetic acid as well as 1% oleyl alcohol polyglycol ether, to the last rinsing liquor during a further washing operation.
• the fabric which has thus been treated then no longer exhibits hardness or stiffness after drying, but has a pleasant soft feel.
• EXAMPLE 2 (1 mole) were reacted with a mixture of 256 g. (1 mole) palmitic acid and 284 g. stearic acid (1 mole) as well as with 10.2 g. acetic anhydride (0.1 mole) by the method described in Example 1. Thereafter, 75 g. of the resultant cation-active compound of the formula 4 with 10.2 g. acetic anhydride (0.1 mole) by the method described in Example 1. 75 g. of the cation-active com- CHzCHa EXAMPLE 3 3 kg.
• EXAMPLE 4 3 kg. of a mixed fabric consisting of polyester fibres and rayon which had been washed and rinsed 20 times in an automatic washing machine with a commercial detergent based on dodecyl-benzene sulphonate and which had become stiff and hard after drying, are treated with the cation-active compound of the formula pound thus obtained were then stirred with 905 g. water, with 10 g. of the reaction product of 25 moles ethylene oxide with 1 mole oleyl alcohol and with 10 g. 100% formic acid by the method described in Example 1 to form an aqueous emulsion.
• R and R are individually defined as alkyl radicals of 11-21 carbon atoms; R is hydrogen or methyl; R is an alkyl radical of 14 carbon atoms; and n is an integer of 0-2.
• R and R are respectively alkyl of 15-17 carbon atoms; R is hydrogen; R is ethyl and n is 1.
• a method for softening washable textiles comprising contacting the textiles with an active amount of a compound of claim 1.
• Washable textiles are cotton, polyacrylonitrile, lWOOl, polyester or rayon, and about 1% by weight of active compound is utilized by weight of dry textile.
