ABSTRACT:
A process for treating a dyed, velvet fabric is disclosed wherein two-toned color effects between the pile and the fabric backing are achieved. The preferred fabric comprises a cellulosic (cotton or rayon) or synthetic fiber weave backing dyed preferably with a non-disperse dye, e.g. a direct dye, and pile composed of cellulose acetate fibers dyed with a disperse dye. The dyed fabric is contacted with a dilute caustic solution, e.g., sodium hydroxide, for a period of time sufficient to at least partially or totally hydrolyze the cellulose acetate of the pile fiber, which noticeably also reduces the color intensity of the pile while having little effect on the color intensity of the backing. This is followed by rinsing, neutralization and conditioning of the treated fabric.
