A waterproof zipper with at least one curve includes a first tape and a second tape, and interlocking elements attached to the first tape and the second tape, wherein the first tape and the second tape are curved, and wherein a curve of at least one of the tapes was caused by compaction of that tape. The zipper is coated on at least one side with a fluid impervious coating.

A fastener stringer used for a slide fastener, including: a pair of fastener tapes including a stretchable yarn; a pair of fastener element rows mounted on opposite side edge portions of the pair of fastener tapes, respectively; and a reflective film disposed on a front or back surface of one of the fastener tapes. The reflective film has stretchability.

In the sector of the production of customized zipper tapes for application on items of apparel and accessories, disclosed is a process for the production of a woven tape with weft effect using a jacquard loom which permits control of each thread of the weft, warp and cord so that the design is not subject to limitations of repetition and length.

A fastener tape, a slide fastener, a skin product, and a method of forming the fastener tape are provided. The method includes forming fabric tapes made from high-melting warp yarns and weft yarns. The fabric tapes each include an outer connecting portion and an inner connecting portion. Fastener teeth are sewn to an outer side of the inner connecting portion through a sewing thread. The inner connecting portion includes an teeth sewing region. A low-melting component is provided in at least the teeth sewing region, and the low-melting component thermally welds the high-melting sewing thread, warp yarns, and weft yarns to form a hardened structure. The method further includes heating, after the fastener teeth are sewn to the fabric tapes, the fabric tapes for bending and shaping, such that the low-melting component thermally welds the sewing thread, the warp yarns, and the weft yarns.

A waterproof zipper with at least one curve includes a first tape and a second tape, and interlocking elements attached to the first tape and the second tape, wherein the first tape and the second tape are curved, and wherein a curve of at least one of the tapes was caused by compaction of that tape. The zipper is coated on at least one side with a fluid impervious coating.

A slide fastener tape is provided. The slide fastener tape extends in a longitudinal direction. The slide fastener includes a weave structure formed with warp threads arranged in the longitudinal direction, and weft threads arranged along a transversal direction perpendicular to the longitudinal direction. The slide fastener tape includes a cord arranged along one side edge portion of the fastener tape. The weft threads are made from filament yarns and the warp threads comprise a plurality of threads made from spun yarn.

A fastener element has a central land portion and first and second bulging portions bulging from the central land portion toward the tape front surface side and the tape rear surface side in the element thickness direction. The first and second bulging portions respectively have a bulging end surface facing to the element thickness direction. The bulging end surface has a quadrilateral base end surface which is long in the element length direction and a tapered protrusion end surface protruding from the base end surface in the element width direction. Thus, it is possible to make the fastener element look like a single-sided metal element and to make a slide fastener which is formed by using the fastener elements lighter than a conventional slide fastener having single-sided metal elements.

Woven and knit substrates having juxtaposed notches with finished edges are disclosed. Such substrates can be used as opposed fastener tapes and fastener elements can be formed, woven, or otherwise added to the opposed fastener tapes in a known fashion. The notched fastener tapes permit the resulting slide fastener to be curved in-plane without buckling either of the opposed the fastener tapes out-of-plane. The finished edges maintain structural integrity of the woven or knit substrates, in stark context to prior art substrates having cut notches. Also disclosed are panelized substrates having curved apertures and incorporating disclosed slide fasteners.

A molded-teeth slide fastener tape for use in a slide fastener assembly includes a woven portion and a plurality of resin-based teeth. The woven portion includes a cord arranged along an edge thereof and a plurality of spaced-apart perforations, disposed adjacent to the cord, which pass completely through the woven portion. Each of the plurality of resin-based teeth is integrally molded to the woven portion along the cord. Each molded tooth encompasses at least a portion of at least one of the spaced-apart perforations so that each molded tooth extends through the at least one of the spaced-apart perforations and fully around a cross-sectional shape of the cord.

A fastener stringer has a fastener tape provided with a tape main body portion and an element attaching portion and a plurality of fastener elements fixed by weaving to the element attaching portion of the fastener tape at the same time of weaving of the fastener tape, and is provided with a weaving structure with one pitch per one-rotation. A weft yarn of the fastener tape has a fineness larger than that of at least a part of a warp yarns disposed in the tape main body portion. Thereby, the productivity of the fastener stringer can be increased to reduce the cost. Further, the density of the weft yarn in the fastener tape can be increased, and the fastener tape can be less likely to be misaligned.
