22 WEFT INSERTION DRAPERY FABRICS ABSTRACT OF THE DISCLOSURE 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.
