Abstract
An improved process of developing an embossed effect in nylon pile fabric, particularly carpet, that comprises selectively contacting the pile surface of the foregoing fabric with a chemical fiber shrinking agent in combination with a penetrant vehicle capable of increasing materially the penetration of the shrinking agent into the fibre surface, and, correspondingly, the depth of embossing caused by the shrinking agent's action in reducing the length of the treated pile.
