Abstract
The present disclosure relates to a reinforcing textile material that comprises a weft-inserted warp knit fabric, in which the warp yarns are configured in a pattern having a majority of successive flat stitches that are used in conjunction with a minority of subsequent successive round stitches. The warp yarn configuration may be represented by the expression x+y, where x is the number of successive needle positions in which a warp yarn is positioned in a flat stitch arrangement and y is the number of subsequent successive needle positions in which the same warp yarn is positioned in a round stitch arrangement. The present weft-inserted warp knit fabrics possess improved dimensional stability, high tensile strength, high tear strength, and a relatively smooth surface, making them well-suited for use as reinforcements in roofing membranes, signs, banners, tents, and the like.
