An aesthetic dimensionally stable fabric suitable for use as drapery and upholstery fabric, or like decorative fabrics, is produced utilizing a weft inserted warp knitting machine having three or more stitching bars. A substrate that is dimensionally stable warp-wise (such as a 100 percent polyester non-woven fabric that is dimensionally stable both warp-wise and weft-wise) is fed to the machine, as are weft yarns. The weft yarns are stitched in place by stitching thread fed to the stitching bars, the two main stitching bars moving in opposite directions in a basically zigzag form to create an aesthetically pleasing effect, but forming a pattern which is not dimensionally stable. However the final fabric produced is dimensionally stable as a result of the substrate properties. The intermediate fabric has selvage areas. Stitching thread is fed to a third stitching bar which is utilized to provide a dimensionally stable stitching pattern in the selvage areas of the fabric to facilitate finishing operations on the fabric, and the zig-zag form is preferably also continued into the selvage areas by one of the two main stitching bars. The selvage may subsequently be removed. The decorative fabric produced may be foam backed, particularly for drapery use.

An intermediate fabric produced in the production of a decorative fabric, the intermediate fabric comprising: a warp-wise dimensionally stable substrate having a first face; weft yarns disposed on the first face of the substrate and extending parallel to each other; stitching thread for holding the weft yarns on the first face; said stitching thread in a central body section of the fabric, between opposite edges thereof in a direction perpendicular to the machine direction, being disposed in a dimensionally unstable, but aesthetic, basically zigzag configuration in the machine direction; and said stitching thread in the selvage portions of said fabric, on opposite sides of the said central body section thereof, being disposed in a dimensionally stable configuration. A method of making a dimensionally stable decorative fabric utilizing a weft-inserted warp knitting machine having three stitching bars, comprising the steps of: (a) feeding a warp-wise stable substrate in the machine direction of a knitting machine; (b) inserting weft yarn in a direction perpendicular to the moving direction of the substrate utilizing the knitting machine; (c) feeding stitching thread to the first and second stitching bars; (c1) feeding stitching thread to the third stitching bar; (d) in a central body portion of the substrate while stitching with the first and second stitching bars, to cause the stitching thread to hold the weft yarn in place on the substrate, moving the stitching bars in opposite directions in a basically zigzag form to create a dimensionally unstable but aesthetic pattern of stitching thread, in the machine direction of the fabric produced; (d1) on selvage edge portions of the substrate in the machine direction, stitching with the third stitching bar while moving it in a pattern so as to create dimensionally stable stitching; practicing steps (c1) and (d1) simultaneously with steps (c) and (d); (e) finishing the fabric produced by steps (a)-(d1); and (f) cutting the finished fabric to form desired fabric pieces.
