ABSTRACT:
The present invention intends to provide a knitted-in slide fastener having a flexibility and capable of securing a desired coupling strength, in which a trace of the fastener element row is unlikely to be made by ironing. A basic structure of knitting of a fastener element attaching portion formed along a side edge of a fastener tape is formed of chain knitting yarns and weft in-laid yarns. A fastener element row is disposed on an upper face of sinker loops of binding chain knitting yarns, attaching portion foundation chain knitting yarns and the weft in-laid yarns and a leg portion of each element portion is tightened and bound by needle loops of the binding chain knitting yarns from an upper face thereof. The weft in-laid yarns inserted such that they are inverted alternately between two rows of wales disposed in the element attaching portion beside the tape main portion have a size larger than other weft yarns. The weft in-laid yarns inserted such that they are inverted alternately between the wale disposed in the element attaching portion nearest to the tape main portion and wales formed by any one of the binding chain knitting yarns have heat shrinkage characteristic. By heating the yarns, a substantially half portion of the fastener element row is sunk below the surface of the fastener tape main portion.
