ABSTRACT:
Among knitting yarns forming stitches of a fastener element attaching portion of a warp knitted tape for a slide fastener composed of multiple wales, a dry heat shrinkage ratio of one or more knitting yarns disposed across adjoining wales such that they at least entangle with another knitting yarn on the wales in the fastener element attaching portion is set lower than a dry heat shrinkage ratio of other knitting yarns composing the warp knitted tape. Preferably, a multifilament yarn composed of fine filament fibers of 0.5 to 4 dTex is used for all the knitting yarns. With such a structure, fastener elements can be sewed accurately, so that a soft warp knitted tape having no hardness due to thermal setting and an excellent drape performance can be obtained, this knitted tape allowing a smooth opening/closing operation of a slider after the fastener elements are mounted.
