ABSTRACT:
A knit slide fastener including a fastener tape composed of a warp-knit ground structure including chain stitches, and a row of continuous coupling elements knit into and along an element-supporting portion of the fastener tape as the fastener tape is knit, wherein a plurality of threads are knit into the element-supporting portion as binding chain stitches, so as to form a group of successive longitudinally interlocked needle loops appearing on the front side and arranged such that in every two adjacent courses, the preceding needle loop overlies an upper leg of one coupling element, and the succeeding needle loop is disposed in a space between the coupling element and an adjacent coupling element at a position close to the ground structure so as to bend or flex the preceding needle loop into an inverted U shape extending embracingly over the upper and lower legs of the coupling element. With this arrangement, the row of coupling elements can be firmly secured to the ground structure of the fastener tape with high dimensional stability, and can always retain a stable attachment posture to insure the functions required in the slide fastener.
