ABSTRACT:
A slide-fastener stringer half comprises an elongated warp-knitted tape having a pair of opposite longitudinally extending edges and a pair of opposite faces and formed with a plurality of longitudinally extending parallel wales. This tape is knit with a plurality of warp yarns each forming a respective lontidudinally extending loop chain extending transversely over two respective wales or needles, a first group of weft yarns laid into and each extending over three of the wales, and a second group of weft yarns laid into and each extending over one of the wales. A continuous monofilamentary coupling element having a succession of turns and lying on one face of the tape along one edge thereof is secured to the tape by stitching which overlies the turns, extends through the tape, and has a needle thread on the other face of the tape between two of the wales at the edge.
