Abstract: A lubricant for molding chlorine-containing thermoplastics, which contains ethylene/acrylic acid or ethylene/maleic acid copolymers esterified, in a molar ratio of carboxyl groups to alcoholic hydroxyl groups of from 1:0.2 to 1:1, with C.sub.1 -C.sub.20 -aliphatic alcohols which may or may not contain ether groups, the copolymers, prior to esterification, having a mean molecular weight of from 500 to 10,000 and containing from 2 to 15% by weight of acrylic acid or from 1 to 8% by weight of maleic acid as copolymerized units, the percentages being based on copolymer.

Abstract: A process for dyeing textile materials, consisting of wool or nylon fibers, with anionic dyes in an aqueous liquor at up to 110.degree. C., wherein dyeing is commenced at a pH of from 7 to 9 and from 0.2 to 5 parts by weight, per 1,000 parts by weight of liquor, of an ester of a saturated C.sub.2 -C.sub.4 -carboxylic acid with an alcohol having a tertiary amino group in the 2-position are added at the dyeing temperature to act as a pH regulator.

Abstract: Polyester fibers are dyed with disperse dyes at temperatures above 100.degree. C. in an aqueous liquor containing, as leveling agents, emulsions of aliphatic esters, nitriles or ketones each containing from 7 to 16 carbon atoms, level shades being obtained.

Abstract: A levelling auxiliary for dyeing fibrous material of polyamide fibers with acid dyes in the acid pH range in the presence of a mixture which contains (based on the solids in each case) from 30 to 90% by weight of a surfactant having sulfonic acid groups and from 10 to 70% by weight of an oxyethylated polyamide which has been prepared by the reaction of 1 part by weight of polyamide with from 2.5 to 3.5 parts by weight of ethylene oxide. Level dyeings devoid of streaks are obtained.

Abstract: Polyester fibers are dyed level shades at above 100.degree. C with disperse dyes from an aqueous liquor containing emulsions of aliphatic alcohols of 8 to 12 carbon atoms.
