ABSTRACT:
A warp-knit slide-fastener stringer half comprises an elongated warp-knitted tape having a pair of opposite faces and a pair of opposite longitudinally extending edges. The tape is knit with a plurality of warp yarns forming longitudinally extending parallel wale-forming chains, a first group of weft yarns laid into and each extending over only three of the chains, and a second group of weft yarns laid into and each extending over only two of the chains. A continuous monofilamentary coupling element having a succession of turns lies on one face of the tape along one edge thereof and is secured thereto by double-lock 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 formed by the chains at the edge. The warp-chain-forming yarns and the weft yarns or either of these in the alternative can be composed of shrinkable threads and thermofixed.
