ABSTRACT:
A durable, multiple-level, pile height is imparted to at least one surface of terry towelling, terry fabric or cut pile cotton fabric by treating the piles in predetermined areas of the surface with caustic paste and allowing the material to stand, with or without heating, so as to shrink and reduce the height of the caustic treated piles. The viscosity, the penetration period, and the manner of applying the paste are selected such that the ground layer of the material is substantially unaffected. The process is compatible with various dyeing techniques to obtain attractive color effects.
