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.

Claims

1. A covering for a floor, wall or ceiling surface comprising:

a primary backing in part exposed on one side of the covering for forming discrete wear surface portions of a wear surface of the covering;

a plurality of yarns tufted into said primary backing along remaining parts of said primary backing forming cut or loop yarns on a back side of said primary backing remote from said wear surface, leaving a plurality of backstitches of the tufted yarns along and forming remaining portions of said wear surface; and

a resin fixing said cut or loop pile tufted yarn along the back side of said primary backing;

said backstitches and said primary backing portions exposed along said wear surface having aesthetic characteristics distinguished from one another.

2. A covering according to claim 1 wherein said primary backing is formed of a woven material having an ultraviolet stabilizer.

3. A covering according to claim 1 wherein each said backstitch extends between a pair of needled openings along the wear surface extending along and in engagement with the primary backing throughout substantially the entirety of the extent of the backstitch between said openings.

4. A covering according to claim 1 wherein said backstitches and primary backing portions have different colorings to afford different aesthetic effects.

5. A covering according to claim 1 including an EVA and calcium carbonate layer underlying the resin.

6. A covering according to claim 5 including a secondary backing comprising a scrim embedded in the EVA and calcium carbonate layer.

7. A covering according to claim 6 wherein said scrim comprises a woven polypropylene.

8. A covering according to claim 1 wherein the tufted yarns are of a continuous loop pile construction.

9. A covering according to claim 1 wherein the tufted yarns are of a cut loop pile construction.

10. A covering according to claim 1 wherein said primary backing is formed of a woven material having an ultraviolet stabilizer, said backstitches and primary backing portions having different colorings to afford different aesthetic effects, an EVA and calcium carbonate layer underlying the resin and a secondary backing comprising a scrim embedded in the EVA and calcium carbonate layer.

11. A covering according to claim 10 wherein said scrim comprises a woven polypropylene, and wherein the tufted yarns are of a continuous loop construction.

12. A covering according to claim 10 wherein said scrim comprises a woven polypropylene, and wherein the tufted yarns are of a cut loop construction.

13. A covering according to claim 1 including a secondary backing underlying said resin and secured to said primary backing by said resin, said secondary backing including a needle-bonded synthetic fiber backing.

14. A covering according to claim 13 wherein said secondary backing includes fibers formed of nylon and polypropylene.

15. A covering according to claim 1 wherein said primary backing comprises a non-woven material formed of synthetic fibers.

16. A covering according to claim 15 wherein said non-woven fiber materials comprise nylon and polyester bonded to one another.

17. A covering according to claim 15 wherein said resin comprises a precoat of polyvinylchloride to fix the cut or loop yarns and a main polyvinylchloride coating having a fiberglass stabilizer underlying the precoat.

18. A covering according to claim 1 wherein the covering comprises broadloom carpeting.

19. A covering according to claim 1 wherein the covering comprises modular carpeting.

20. A covering for a floor, wall or ceiling surface comprising:

a woven primary backing having tufted and non-tufted portions on one side thereof exposed for forming discrete wear surface portions of a wear surface of the covering;

said tufted portions including a plurality of yarns tufted into said primary backing and formed of cut or loop yarns on a back side of said primary backing remote from said wear surface, leaving a plurality of backstitches of the tufted yarns along and forming part of said wear surface; and

a resin fixing said cut or loop tufted yarns along the back side of said primary backing;

said non-tufted portions comprising warp and weft yarns of said primary backing;

said tufted and non-tufted portions of said primary backing exposed along said wear surface having aesthetic characteristics distinguished from one another.
