  • Patent number: 4682480
    Abstract: A warp knit fabric comprises a substrate (preferably a non-woven fabric), plural warp yarns laid on a face of the substrate, plural weft yarns laid over the warp yarns, and plural stitch wales spaced-apart along the warp-wise direction of the fabric and being stitched through the substrate to hold the weft and warp yarns in position thereon. In such a manner, the warp yarns are interposed between the inserted weft yarns and the substrate face. A method and apparatus is also disclosed whereby the substrate and plural weft yarns are fed to a knitting area while concurrently interposing the warp yarns between a face of the substrate and the weft yarns. The weft yarns are then inserted into stitches of warp knitting yarns formed by stitching the warp knitting yarns, at the knitting ara, through the substrate so as to hold the weft-inserted yarns, and thus the interposed warp yarns, to the substrate face.
