ABSTRACT:
A textile substrate is dyed by immersing it in a gathered configuration into an oil medium containing a dissolved or dispersed dye for a sufficient time to allow the oil medium to come into contact with part but not all of the surface of the substrate and the thus-treated substrate is then preferably immersed in an aqueous medium having another dye dissolved or dispersed therein.
