Abstract: A fastener stringer is configured such that a fastener element of a continuous shape includes a plurality of fine projected rims which are continuously disposed on a peripheral surface of the monofilament (30); along a length direction of the monofilament and a plurality of fine concave grooves which are disposed between the projected rim and in a cross section of the monofilament, a cross-sectional area of a space region of the concave groove is set to be larger than that of the projected rim. With this configuration, when performing dyeing process employing a beam dyeing or a continuous dyeing method while appropriately securing the strength of the monofilament, it is possible to prevent dyeing irregularities and dyeing defects from arising. Further, when performing a coloring according to an inkjet, scheme, it is possible to finely form a desired pattern with clear outlines on the fastener element.

Abstract: For this fastener stringer, at least two stitching lines configured of stitching thread are disposed along the longitudinal direction of a tape on one surface side of the fastener elements. Each of the stitching lines has a stitch at least every two pitches of the fastener elements in the longitudinal direction of the tape and the stitches of each line are disposed so as to deviate from the stitches of the adjacent line, by at least one pitch of the fastener elements in the longitudinal direction of the tape. The fastener stringer thereby has superior fastener element dimensional precision, stitch line abrasion resistance, and flexibility. The multiple stitch lines can be made to look like a tape fabric to be inconspicuous. Moreover, in producing the fastener stringer, a stitching process of the fastener element can be performed efficiently and stably.

Abstract: The invention provides a linear slide fastener wherein a concave portion accommodating a fixing thread for fixing a fastener tape is provided on a top face of an upper leg portion of a coil-like/zigzag-like linear fastener element, when dimensions from a bottom face of a lower leg portion to a top face of the upper leg portion on a coupling head side, at the concave portion and on an inverted portion side are assumed to be H1, H2 and H3, a setting condition of H1>H3>H2 is satisfied and when dimensions from a bottom face of the upper leg portion to a top face of the lower leg portion within a gap portion on the coupling head side, at a convex portion and on the inverted portion side are assumed to be H4, H5 and H6 respectively, a setting condition of H4>H6>H5 is satisfied.

Abstract: A slide fastener comprising a pair of stranger tapes, each including an elongated tape body including a plurality of warp threads and a beaded longitudinal edge portion provided on one longitudinal edge of the elongated tape body, the beaded marginal portion including a tube formed integrally with the elongated tape body and a plurality of filler threads inserted through the tube in such a way not to be intertwined with each other, the filler threads being identical in denier with the warp thread; and two rows of coupling elements extruded from plastics and each mounted on the respective beaded edge, each element comprising a coupling head and a pair of clamping legs extending rearward from the coupling head, each row of coupling elements being connected with two connecting rods embedded in the legs, each element clamp-mounted on the beaded edge with the legs sewn to the beaded edge by sewn stitches.

Abstract: A separable slide fastener has a pair of warp-knit stringer tapes each with a series of longitudinal openings for easy attachment to a knit fabric. Each of the stringer tapes includes a reinforcing body mounted on a lower end portion thereof and including a thin member and an endmost thick member both extending transversely across some of the tape opening, the thin member covering at least the endmost opening and the endmost thick body having a transverse portion contiguous to the thin member in the longitudinal direction of the stringer tape and extending about a portion of the thin member and the lower end portion of the stringer tape. A separable bottom end stop is injection-molded on the thin reinforcement member bonded to the stringer tape so as to form integrally therewith the thick reinforcement member.

Abstract: A separable slide fastener has a pair of warp-knit stringer tapes each with a series of openings for easy attachment to a knit fabric. Each of the stringer tapes includes a reinforcement film bonded to a lower end portion thereof and having a recess which allows some of the tape openings to be exposed for use in attachment to the knit fabric. The recess may be covered with a thin layer penetratable by knitting needles. A separable bottom end stop is injection-molded on the reinforcement films bonded to the stringer tapes.

Abstract: A separable slide fastener comprises a pair of warp-knit stringer tapes each having a pair of webs with a wale-free region therebetween, which are interconnected by a connector thread extending across the wale-free region at longitudinal intervals, the wale-free region being receptive of a chain of thread loops for attaching the stringer tape to a fabric. A pair of rows of coupling elements is mounted on opposite longitudinal edges of the stringer tapes, respectively and taken into and out of interdigitating engagement by a slider movable along the rows of coupling elements. The stringer tapes have at one end thereof a separable bottom end stop. A reinforcement member is mounted on each of the stringer tapes at the one end thereof and connected to the separable bottom end stop.
