Abstract
In a knit slide fastener in which a continuous fastener element row is knitted in a fastener element attaching portion of each fastener tape simultaneously with the knitting of the fastener tape, a plurality of laid-in weft yarns are knitted in the warp-knit structure of the fastener element attaching portion so as to turn alternately in every course and to be interlaced with knit loops of a chain stitch extending along the outermost edge of the fastener element attaching portion, and the fastener element row is secured to the ground structure of the attaching portion by two binding chain stitches.
Claims2
A knit slide fastener comprising:
- (a) a pair of fastener tapes each composed of a warp-knit ground structure having a fastener element attaching portion at a longitudinal edge portion thereof;
- (b) a pair of continuous fastener element rows each knitted in one of said fastener element attaching portions simultaneously with the knitting of the respective fastener tape;
- (c) a plurality of binding chain stitches knitted in each said fastener element attaching portion to bind each said fastener element row to a ground structure of each said fastener element attaching portion;
- (d) a plurality of laid-in weft yarns laid in said fastener element attaching portion;
- and
- (d) an edge chain stitch having a succession of knit loops extending along an outermost edge of each said fastener element attaching portion, every one of said knit loops being interlaced with one of said laid-in weft yarns, and excluding said fastener elements to form the ground structure of said fastener element attaching portion.
