摘要：<p>Novel dyeing process for improving the levelness of cellulose dyeings with vat dyes or anionic dyes and for preventing creases in the dyed goods. The process according to the invention comprises dyeing the cellulose fibre material in the presence of a polypropylene oxide adduct, or of a salt thereof, which adduct contains carboxyl groups and has been prepared from a) an aliphatic diol which has an average molecular weight of not more than 2,600, b) an aliphatic dicarboxylic acid,- or its anhydride, having 4 to 10 carbon atoms, c) an adduct of propylene oxide with an aliphatic alcohol which is at least trihydric and has 3 to 10 carbon atoms and d) a fatty acid having 8 to 22 carbon atoms. Dyeing is preferably effected by the exhaustion process. Fibre mixtures, for example of polyester/ cotton, can also be dyed.</p>
