Abstract: The present invention provides a process for the rapid dyeing of a series of successive garments or batches of garments with a vat dye, preferably indigo dye, wherein the garments while contained are submerged in and impregnated with the dyeing solution in a first bath, then removed from it while draining the dyeing solution and conserving it for re-use, then promptly immersed in an oxidizing solution in a second bath so as to shock oxidize the dye present in the garments, then removed from the oxidizing bath while draining the oxidizing solution and preserving it for re-use, and then washed and dried, and wherein the time elapsed between removal of the garments from the dyeing solution and their immersion in the oxidizing solution is less than 5 minutes.

Abstract: The present invention provides a process for the rapid room temperature dyeing of a series of successive garments with a vat dye, preferably indigo dye, wherein the garments while supported on supports that keep all fabric surfaces of each garment accessible to treating solutions are first uniformly impregnated with the dye solution in a first bath and then immersed in an oxidizing solution in a second bath so as to uniformly oxidize the dye present in the garments.
