IMPROVEMENT IN A PROCESS FOR THE CONTINUOUS DYESING OF FLAT TEXTILE STRUCTURES MADE OF CELLULOSIC FIBERS AND THEIR MIXTURE WITH SYNTHETIC FIBERS

摘要

Continuous dyeing of textile webs of cellulose fibers and of mixtures thereof with synthetic fibers using reactive dyes, by applying onto the textile material an aqueous solution of at least one reactive dye in conjunction with a mixture of fixation agents of a liquid alkali water glass having a density from 37 DEG to 60 DEG Be and an alkali hydroxide solution having a density from 30 DEG to 45 DEG Be, introducing the treated material into a tank where it is heated and subjected to the action of humid heat of 81 DEG to 95 DEG C. for 5 to 180 seconds, removing it continuously from the tank and then terminating the dyestuff fixation by brief steaming or by a brief immersion into a hot sodium silicate solution.
