    摘要： Continuous dyeing of cellulose-containing yarn with indigo in a single operation is disclosed, in that the reduced indigo from an aqueous dye liquor containing reducing agents, alkali, and additionally a further dissolved alkali metal salt in a concentration of 200 to 350 g/l as the electrolyte, and whose pH value has been adjusted to 10.2 to 11.3, is applied to the yarn. The reduced indigo absorbed by the fibers is oxidized again to pigment while maintaining the high concentration of electrolyte, and the dye process is finished in the customary manner.

    摘要： The disclosure is a process for batchwise dyeing of cellulosic textile material with indigo by the exhaust method, which comprises applying the reduced indigo to the textile material from an aqueous dyeing liquor which includes a reductant, an alkali and additionally a further dissolved alkali metal salt in a concentration of from 200 to 350 g/l as electrolyte and whose pH has been set to 10.2-11.3, oxidizing the reduced indigo on the fiber back to the pigment while maintaining the high electrolyte concentration, and finishing the dyeing in a conventional manner.

    摘要： A process for continuous dyeing of cellulose-containing yarn with indigo in a single passage applies reduced indigo from an aqueous dye liquor containing deoxidants, alkali and a dissolved alkali metal salt at a concentration of 100 to 200 g/l as an electrolyte at a pH value of the liquor adjusted to about 10.2 to 11.3, while maintaining the electrolyte concentration, exposing the yarn to a gas which dissolves in the aqueous medium while forming an acid, and then oxidizing reduced indigo in the yarn to form pigment and finishing the dyeing process in a customary manner.
