ABSTRACT:
A warp-knit stringer tape, for slide fasteners suitable for use on knit garments, has a double-faced structure having a plurality of wales on opposite sides. The stringer tape includes a longitudinally stretchable elongate web portion, and a longitudinal non-stretchable marginal portion extending along one longitudinal edge of the web portion for supporting a row of coupling elements of the slide fastener. In the web portion, textured yarns are used for a plurality of threads extending longitudinally of the wales and forming stitch loops therealong. In the marginal portion, a gray yarn having a coefficient of thermal shrinkage higher than that of the textured yarns is used for a core thread.
