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.
