Abstract
The invention intends to provide a slide fastener tape capable of securing flexibility and attaching strength without losing proper flexibility of knitted fabric and having a warp knitting structure allowing an element to be attached uniformly. In this slide fastener tape, its element attaching portion is knitted with warp yarn integrally with a tape main body along a side edge thereof formed by warp knitting structure of one needle row of double row needles. The slide fastener tape is composed of plural groups of double tricot knitting structures lapped alternately between double row needles so as to surround a peripheral face of a core material and a knitting structure which is part of the tape main body. Needle loops of the knitting structure, which is part of the tape main body, are overlapped with needle loops, which are part of the double tricot knitting structure. Consequently, swellings of front and rear surfaces across the tape face in the element attaching portion are substantially equal, thereby securing flexibility and attaching strength of an element and allowing the element to be attached uniformly.
