    Abstract: A process of making a cut pile, tufted carpet that is non-directional is disclosed. It comprises the steps of:(a) knitting a yarn composed of thermoplastic fiber, e.g., continuous filament polypropylene ribbon, 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 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,(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.

    Abstract: A substantially non-compacting carpet padding of controlled resiliency in flat sheet form comprising a mixture of staple fibers having lower indexes of resiliency and memory than is desired for such padding and flexible foam plastic granules having a greater index of resiliency than is desired for such padding and having a high index of memory, said fibers and granules being interengaged and interrelated whereby the fibers are acted upon by the granules to compensate for their lack of resiliency and memory and the granules are acted upon by the fibers to buffer and to compensate for their excess of resiliency.
