Summary:Process for continuous dyeing of cellulosic circular knits composed of natural or modified hydroxy-containing or natural, modified or synthetic carboxamido-containing fiber materials with water-soluble dyes comprises initially impregnating the material with an aqueous dye solution, optionally comprising auxiliaries, in the course of the dyeing step, reducing the liquor content to 400% by weight, based on weight of fiber, by squeezing means customary for tubular material, and subsequently subjecting the liquor-comprising material to a leveling and fixing step for the dye applied to the material by transporting the rope of material continuously through the machine unit by means of the flowing dyeing liquor at a liquor ratio of up to 10:1.
