Abstract

Abstract Agent for the liquid paraffin waxing of yarns which consists of (a) from 5 to 20% of paraffin, melting range of 45° to 60° C.; (b) from 2 to 10% of one or several alkyl imidazolines of the formula I ##STR1## in which R is C 12 -C 22 -alkyl, alkenyl or hydroxyalkyl, R 1 is hydrogen or C 1 -C 22 -saturated or unsaturated aliphatic or aromatic acyl, R 2 is hydrogen, C 1 -C 4 -alkyl or C 1 -C 4 -hydroxyalkyl, n is a number of from 2 to 6, and X is a halogen anion, a C 1 -C 4 -alkyl sulfate anion, a C 1 -C 4 -dialkyl phosphate anion, or a C 1 -C 4 -alkyl carboxylate anion; (c) from 1 to 5% of one or several aminoxides of the formula II ##STR2## in which R is C 8 -C 12 -alkyl or alkenyl, R 1 is C 1 -C 4 -alkyl, R 2 is hydrogen or C 1 -C 4 -alkyl, and n is a number of from 0 to 6, and (d) from 5 to 20% of one or several polyglycol ethers of the formula III R--O--(C.sub.2 H.sub.4 O).sub.n --H III, in which R is C 8 -C 18 -alkyl or alkenyl and n is a number of from 3 to 12, as well as water ad 100%.
