    摘要: A process for the simultaneous dyeing and crease-proof finishing of textile material consisting of cellulose fibers or blends of cellulose fibers and polyester fibers by impregnating the textile material with an aqueous bath containing a reactive or vat dyestuff or a disperse dyestuff and a reactive or vat dyestuff, N-methylol-acrylamide or N,N-dimethylol-methyl-bis-acrylamide or an ether thereof with an alkanol containing 1 to 3 carbon atoms as well as an acid catalyst, dry heating the material to condense the N-methylol group of the synthetic resin and optionally fixing the disperse dyestuff at the same time, and in a second fixation step simultaneously fixing the reactive or vat dyestuff and the ambivalent cross-linking agent in an alkaline medium, and then after-treating the material by washing operations.
