Process for the printing and continuous fixing of disperse dyestuffs on polyester, cellulose-triacetate, cellulose-2{178 -acetate and mixtures thereof

Abstract

Abstract WHEREIN X IS ZERO OR A NUMBER OF FROM 1 TO 4, ARE USED AS FIXING AUXILIARIES. The prints which are prepared by using these fixing auxiliaries are distinguished by a good to excellent dyestuff yield with brilliant shades, they have a good to very good fastness to light and to use required for textile materials. Furthermore, the fixing auxiliaries facilitate the elimination of the carriers also used by their emulsifying properties in the usual aftertreatments of dyeings and prints by rinsing, so that the shades are protected from being spoiled and the fastness to light is increased. A process for printing and continuously fixing prints of disperse dyestuffs on fibrous materials of polyester, cellulosetriacetate and cellulose-2 1/2 -acetate and mixtures thereof or mixtures with wool, natural or regenerated cellulose fibers or with other synthetic fibers, wherein compounds of the formula (1) R1-CO-(OC2H4)n-O-C4H8-O-(C2H4O)m-OC-R2(1) wherein R1-CO- and R2-CO- each represents the acyl radicals of linear or branched alkane- or alkene monocarboxylic acids with from 12 to 22 carbon atoms and n and m each is a number of from 4 to 12, alone, or in combination with oxethylated naphtols of the formula (2)
