    Abstract: A process of making a cut pile, tufted carpet that has the tightly curled appearance of Persian lamb is dislcosed. It comprises the steps of:(a) knitting a synthetic carpet facing yarn, e.g., a continuous filament nylon, into a deknittable fabric,(b) heating the fabric to a temperature at which the curves and bends generated in the yarn by its knitted configuration are established in the yarn's memory,(c) cooling the fabric to about room temperature,(d) deknitting the cooled fabric and rewinding the unravelled yarn under enough tension to restraighten it,(e) tufting the yarn as facing yarn into a primary carpet backing material, forming a cut pile carpet, which then can be dyed,(f) coating the underside of the carpet with a heat-settable adhesive that, when cured, will help anchor the tufts of yarn in the backing material, and(g) heating the adhesive-coated carpet to a temperature at which the adhesive will set and the facing yarn will reconform to the bends and twists in its memory.
