ABSTRACT:
A fastener stringer comprises a warp-knit tape and a row of interlocking fastener elements secured thereto. The tape has a web portion formed by chain stitches defining longitudinally extending wales, tricot stitches extending diagonally across and between a plurality of adjacent wales, and laid-in weft threads extending over and connecting every four wales. The tape also has a longitudinal edge portion consisting solely of knit-loop forming threads. Both of the portions are interconnected transversely of the tape by threads constituting the web portion and edge portion, respectively. One of the wales adjacent the longitudinal edge portion is biased toward the web portion to widen an interwale valley between the above-mentioned one of wales and its neighboring wale.
