ABSTRACT:
Process for the continuous dyeing of flat textile structures made of cellulose fibers and their mixtures with synthetic fiber materials by applying onto the web of fibrous material an aqueous solution of at least one reactive dyestuff and a fixation agent mixture of a liquid alkali metal silicate of the formula Me.sub.2.sup.I .multidot.x SiO.sub.2 (x=3-5) (water glass) and an aqueous alkali metal hydroxide solution, placing the material thus treated into a dwelling chamber, exposing the material in a cuttled-up or opened-out condition in said chamber to humid heat, so that the dyestuff is fixed by the dwelling operation, and finally removing the material again continuously from the dwelling chamber.
