Padding auxiliaries and processes for dyeing cellulose fibers or
mixtures of cellulose fibers and synthetic fibers with sulphur
dyestuffs, sulphur vat dyestuffs, vat dyestuffs and reactive dyestuffs
摘要:
A padding auxiliary is used in a dyeing process using a padding liquor wherein the padding auxiliary is an aqueous solution or dispersion containing(a) 20 to 50 percent by weight of a mixture of 50 to 100 percent by weight of a compound of the following formula ##STR1## and 50 to 0 percent by weight of a compound of the following formula ##STR2## (b) b percent by weight of a compound of the formula ##STR3## and (c) c percent by weight of a compound of the formula ##STR4## wherein b is a number from 0 to 5, c is a number from 0 to 5 and the numbers for b and c are chosen such that the sum of the numbers for b and c is a number from 1 to 10;R.sup.1, R.sup.2 and R.sup.3 are independently an aliphatic moiety with 5 to 12 carbon atoms or an araliphatic moiety with 7 to 13 carbon atoms;X.sym., Y.sym. and Z.sym. is each independently an alkali metal cation, ammonium cation or a cation of an alkylamine or hydroxyalkylamine wherein the alkyl has 1-12 carbon atoms;R.sup.4 is an aliphatic moiety with 1 to 8 carbon atoms, phenyl, alkylphenyl with 7 to 10 carbon atoms or phenylalkyl with 7 to 10 carbon atoms;R.sup.5 is hydrogen or an aliphatic moiety with 1 to 8 carbon atoms, phenyl, alkylphenyl with 7 to 10 carbon atom or phenylalkyl with 7 to 10 carbon atoms;y and z are independently integers from 6 to 8;n a number from 15 to 35;m and p are the same number and their sum is a number from 2 to 120 with n and the sum of m and p being chosen such that ##EQU1##
