    摘要: Process for the continuous production of surface dyeings on cellulose fiber textile materials, characterized in that the textile materials are treated with an aqueous liquor containing at least 5 g/l of benzyl halide quaternized condensation products of precondensates of trialkanolamines and ureas, cyclic carbonates and/or epihalohydrins and/or benzyl chloride quaternized condensation products of piperazine and epichloronydrin, and 0.02 to 1 g/l of a phosphoric triester whose alcohol component has 6 to 18 carbon atoms, the textile materials thus treated are then dyed in another bath with reactive dyes in an aqueous medium and the dyes are fixed by treatment with an alkaline aqueous liquor and the dyeing finished in conventional manner. The individual cellulose fibers of the textile material are not completely penetrated by the dye but, on the contrary, exhibit ring dyeing.

    摘要: An improved process for dyeing or printing water-swellable cellulosic fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent which maintains swelling of the cellulose if water is removed and which is a solvent for the disperse dye, and heating the contacted fibers to effect fixation of the dye, the improvement comprising using as water-soluble solvent a mixture of(a) polyethylene oxide, a block copolymer of ethylene oxide and propylene oxide or an ether, ester or carbamate derivative thereof and(b) a polyoxyethylated amine.
