Abstract

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.
