Abstract
A reflecting warp-knit slide fastener tape is knitted with several kinds of knitting patterns. A marginal portion onto which fastener elements are attached extends along one longitudinal edge of the tape. The marginal portion is formed by tricot-stitch yarns, weft-inlaid yarns, and chain-stitch yarns which prevent the marginal portion from stretching. In the web portion, in addition to the tricot-stitch yarns and the weft-inlaid yarns one or more reflective members, which is in the form of a strip of retroreflective or light-reserve reflective film, are knitted in between wales contiguous to the marginal portion. The reflective members are sandwiched between the weft-inlaid and tricot-stitch yarns. The tricot-stitch yarns are transparent synthetic fiber yarns in order not to obstruct the reflecting feature of the reflective members. The resulting reflecting portion is exposed to the front surface of the tape continuously along its entire length, giving a neat appearance particularly suitable for the dress and the traffic-safety clothing as well.
