Abstract
Warp and weft yarns are alternately laid one on top of the other and the weft yarns are stitched to provide a woven-like fabric appearance. At least one weft yarn is provided in each stitch course between the stitch loop and the underlap, the stitching forming no part of the interlacing and the woven-like fabric appearance.
