ABSTRACT:
Process for fixing prints with reactive dyestuffs on textile materials of native or regenerated fibers and fiber mixtures which contain such fibers in admixture with synthetic fibers, which process comprises printing reactive dyestuffs having the usual printing paste composition on the textile material, drying, impregnating with an alkali mixture of liquid alkali water glass of 37.degree.-52.degree. Be and concentrated sodium hydroxide solution of 38.degree.-50.degree. Be at pH 10-14, preferably 11-12, and fixing. By this process the drawbacks of using either a sodium hydroxide soluion or liquid alkali water glass alone are avoided. The fixing solution is rendered more fluid to such an extent that less liquor is consumed, the heating of the liquor is made superfluous, deposits on the rolls are avoided, the material to be printed is more rapidly wetted, the fabric webs do not dry on or stick together during the dwelling periods and thus the process is rendered more economical in total.
