Abstract
A floor covering includes a primary backing having yarns tufted through the primary backing forming wear surface portions comprised of the back stitches of the tufted yarns in conjunction with non-tufted areas of the primary backing, also forming exposed wear surfaces. Both exposed wear surfaces portions form an aesthetic design pattern whereby a low, dense broadloom or modular carpet is provided at reduced materials and costs. Preferably, the primary backing is comprised of a woven polypropylene and a secondary backing is provided with the cut or loop yarns on the back side of the primary backing being fixed in place by a resin. A secondary backing formed of a composition of EVA, calcium carbonate and resin, overlaid by a woven scrim, is provided. The secondary backing may be formed of a needle-bonded synthetic fiber. Additionally, the primary backing may be formed of a non-woven material such as nylon and polyester.
