ABSTRACT:
Pile fabrics, which have been prepared from nylon carpet fibers having a textured or embossed surface induced by a chemical shrinking process for developing the texture of the fabric, involving selectively contacting the surface of certain areas of the carpet with a chemical fiber shrinking agent for the nylon fibers and allowing the shrinking action to occur, and thereafter, removing the shrinking agent from the fibers, the thus treated areas, thereafter, showing a reduced height of pile to create the texture of the fabric, are kept soft in the treated areas by simultaneously incorporating in the shrinking material, or of the dye composition used as a combination color and shrinking material, a protective agent compatible with the fiber and also one which is not destroyed by the chemical nature of the shrinking or dyeing compositon to maintain the shrunk fibers soft and pliant.
