ABSTRACT:
A slide fastener stringer includes a warp-knit stringer tape comprising a first set of yarns forming a knit ground structure containing stitch loops in every course and wale of the tape, and a second set of yarns knit in the ground structure and each extending coursewise across at least one wale, the yarns of second set comprising textured yarns. A third set of yarns forms a plurality of chains of loops knit in the ground structure and extending along wales in at least one edge portion of the tape. A fourth set of yarns is laid in the ground structure and extends in and along the wales in the tape edge portion, on which a row of coupling elements is mounted. With the stringer tape thus constructed, the tape edge portion is tight and resistant to walewise stretch and the remainder portion is relatively coarse and roughened.
