Title: Improvements in or relating to polyoxyalkylated amine salts and process for the treatment of textile materials

Abstract: The invention comprises compounds forming, in aqueous solution, a cation of formula I <FORM:1006787/C3/1> in which A represents a lipophilic organic radical of 8-22 carbon atoms, B represents an alkylene radical with 2 or 3 carbon atoms joining the basic nitrogen atoms directly, and each of U and V represents a hydrogen atom, an alkyl radical of 1 to 10 carbon atoms or an aryl-alkyl radical in which the alkyl has 1 to 10 carbons, each of R1, R2, R3, Q1, Q2 and Q3 is a hydrogen atom or aliphatic radical, with the proviso that the radical pairs R1 and Q1, R2 and Q2, R3 and Q3 may optionally form a ring and that not all the radicals R and Q may simultaneously indicate hydrogen atoms, each of r1, r2 and r3 is 1, 2 or 3, with the proviso that not all may simultaneously be 1, m is a number in the range 1-5 inclusive, each of n, p and q represents a whole number in the range of 0-200 while n+p+q must amount to 40-200, with the proviso that said cation must contain at least one <FORM:1006787/C3/2> radical in which one of R1, R2, R3, Q1, Q2 and Q3 signifies an aliphatic radical.  The novel compounds may be made by adding to an amine of formula II and oxirane of formula III <FORM:1006787/C3/3> <FORM:1006787/C3/4> in which each of Ra and Qa represents a hydrogen atom or an aliphatic radical, with the proviso that Ra and Qa may not both be hydrogen atoms but may constitute a ring, whereby an addition product <FORM:1006787/C3/5> results, reacting said addition product with an agent suitable for introducing polyethyleneglycol radicals and the resulting compound of formula <FORM:1006787/C3/6> is optionally further reacted with a quaternizing agent of structure such that the required radicals U and V are introduced. Suitable amines and oxirane compounds are specified.  The preferred agent for introducing polyethylenoxy groups is ethylene oxide, but it is also possible to use halogenoethylpolyglycol ethers. Suitable quaternizing agents are given.ALSO:Level dyeings of textile materials are made using as levelling agent a compound which in aqueous solution forms a cation of the formula: <FORM:1006787/D1-D2/1> in which A represents a lipophilic organic radical of 8-22 carbon atoms, B represents an alkylene radical with 2 or 3 carbon atoms joining the basic nitrogen atoms directly, and each of U and V represents a hydrogen atom, an alkyl radical of 1 to 10 or an aryl-alkyl radical in which the alkyl has 1 to 10 carbons, each of R1,RR2, R3, Q1, Q2 and Q3 is a hydrogen atom or aliphatic radical, with the proviso that the radical pairs R1 and Q1, R2 and Q2, and R3 and Q3 may optionally form a ring and that not all the radicals R and Q may simultaneously indicate hydrogen atoms, each of r1, r2 and r3 is 1, 2 or 3, but not all may be 1 simultaneously, m is a number in the range 1 to 5, each of n, p and q represents a whole number in the range of 0-200 while n + p + q must amount to 40-200, with the proviso that said cation must contain at least one <FORM:1006787/D1-D2/2> radical in which one of R1, R2, R3, Q1, Q2 and Q3 signifies an aliphatic radical.  The textile material may be cotton, regenerated cellulose, wool or synthetic fibres (e.g. polyamide, polyurethane or polyester fibres), or it may consist of mixtures of such fibres, and the dyestuffs may be acid wool dyes, direct dyes, vat dyes or dispersion dyes.  The agents are especially suitable for obtaining level shades in dyeing with metal complex dyestuffs used in a neutral bath and/or with metal free wool dyestuffs used in weakly acid bath.  The agents may be added to the dyebath before or during the dyeing process.
