Abstract

A wallcovering material having a paper backing being color and/or design printed face to which substantially parallel warp and fill yarns are tricot stitched thereto to provide an aesthetic structure through which the color and/or design shows through. The warp and weft yarns are knit to the paper backing material and held firmly in place by the polyethylene film on the face of the paper backing. The warp and weft yarns are openly spaced so that the color and/or design printed on the paper shows through and provides a pleasant view to the area in which the wallcovering is installed.

Claims

1. A wallcovering product comprising:

a web of paper material having a face side and a back side with a color or design on the face side thereof, a layer of thermoplastic material on the face side of paper material, a plurality of weft yarns substantially parallel to one another laying on said layer of thermoplastic material transverse of said web of paper material, a plurality of warp yarns substantially parallel to one another laying on said layer of thermoplastic material substantially perpendicular to said weft yarns and a plurality of stitching yarns through said web of paper material securing said warp and weft yarns, said layer of thermoplastic material fusing said warp and weft yarns to said paper material, said warp yarns being spaced from another and being in number in the range of 3 to 14 per inch and the number of weft yarns being an average of 1/2 to 2 per course of stitch yarns to allow a visual view of the color or design on said web of paper material.

2. The product of claim 1 wherein said weft yarns are under said warp yarns next adjacent to said layer of thermoplastic material.

3. The product of claim 2 wherein each of said plurality of stitching yarns is knit in a tricot stitch.

4. The product of claim 3 wherein said thermoplastic material is polyethylene.

5. The product of claim 4 wherein said number of warp yarns per inch is seven (7).

6. The product of claim 5 wherein the number of weft yarns averages 1 per course.
