Abstract: A process for dyeing polyester fibers which do not require a carrier with disperse dyes by the exhaustion method at 20 DEG -100 DEG C. and pH 4-6, with liquor ratios of from 5:1 to 100:1, and dyeing times of from 30 to 180 minutes, wherein the dyeing is carried out in the presence of from 0.5 to 20%, based on fiber weight, of a leveling agent consisting of an adduct of a C5-C14-alkylphenol or C5-C14-alkylnaphthol with from 4 to 25 moles of ethylene oxide.

Abstract: In the washing-out of unfixed reactive dyes from cellulose fibres or their blends with other fibres, by aq. baths of 15-100 degrees C, an alkoxylated polyamine and with cloud point of a 1% aq. soln. of 18 degrees C min. is used. This is made by reaction of 100 parts amine with at least 2N atoms and at least one alkoxylatable gp. in an N atom, with 50-10000 parts of (a) ethylene oxide, and (b) propylene oxide or butylene oxide, or mixts. of (a) and (b) in molar ratio 0.2-5:1. Washing efficiency is improved over that of known nontoxic surfactants, resulting in better wash-fastness of the dyed prod.
