Knit slide fastener

A knit slide fastener including a fastener tape composed of a warp-knit ground structure and having an element-supporting portion along one longitudinal edge thereof, and a row of continuous coupling elements knit into and along said element-supporting portion as said fastener tape is knit, each of said coupling elements having a pair of legs, wherein the improvement comprises:

• at least two parallel juxtaposed threads knit as binding chain stitches of a double-knit structure into said element-supporting portion, each of said binding chain-stitch threads having a series of upper needle loops and a series of lower needle loops;
• at least one thread knit as tricot stitches forming a part of said warp-knit ground structure at said element-supporting portion, said tricot-stitch thread having a plurality of needle loops;
• and
• at least one thread knit as binding tricot stitches extending on and along an upper surface of said row of continuous coupling elements, said binding tricot-stitch thread having a plurality of needle loops,
• wherein said upper needle loops and lower needle loops of said binding chain-stitch threads are intertwined respectively with said needle loops of said binding tricot-stitch thread and said needle loops of said tricot-stitch thread to secure said row of continuous coupling elements to said element-supporting portion, with said legs restrained between said tricot stitches and said binding tricot stitches.
