Hereinafter, an embodiment of the zipper of the present invention will be described in detail with reference to the drawings. In the following description, regarding the fastener chain cloth, the front side refers to the front side with respect to the paper surface of FIG. 1, the back side refers to the back side of the paper surface of FIG. 1, and the upper side refers to the paper side of FIG. The upper side, the lower side refers to the lower side of the paper surface relative to FIG. 1, the left side refers to the left side of the paper surface of FIG. 1, and the right side refers to the right side of the paper surface of FIG. Moreover, the left-right direction of the zipper chain cloth is also called the width direction. Moreover, the upper and lower directions of the zipper chain cloth are also referred to as the length direction. Regarding the fastener element, the upper side refers to the front side with respect to the paper surface of Fig. 1, and the lower side refers to the inner side with respect to the paper surface of Fig. 1.

As shown in Fig. 1, the slide fastener 10 of the present embodiment includes a pair of right and left fastener chain fabrics 20, which are woven into a chain fabric, and a pair of left and right fastener element rows 30, which are respectively attached to the left and right zipper chain cloths. 20 opposite side chain edge portion 20a; slider 40, the left and right fastener element row 30 is engaged and disengaged; upper stop portion 11 is respectively disposed at the upper end of the left and right fastener element row 30; And a lower stop portion 12 disposed at a lower end portion of the left and right fastener element rows 30. Furthermore, the lower stop portion 12 can also be an opening and closing member.

As shown in FIG. 2, the fastener element row 30 is a spiral fastener element row formed by winding a synthetic resin monofilament in a fixed direction, and has a plurality of fastener element 31. Further, the fastener element row 30 is inserted into the core cord 32, and is sewn to the surface (upper surface) of the chain side edge portion 20a of the fastener stringer 20 by the double loop stitch 33. Further, examples of the synthetic resin material of the monofilament include polyester and nylon.

The fastener element 31 includes an engaging head portion 31a that meshes with and separates from the opposing fastener element 31, and an upper leg portion 31b that extends outward in the width direction from the upper end portion of the engaging head portion 31a, and a lower leg portion 31c that is self-engaging The lower end portion of the head portion 31a extends outward in the width direction, and the connecting portion 31d connects the end portion in the width direction of the upper leg portion 31b and the end portion in the width direction of the lower leg portion 31c of the adjacent fastener element 31.

As shown in FIG. 1, the slider 40 includes a main body 41, a pull-tab mounting portion 42 that is provided to the main body 41, and a pull tab 43 that is attached to the pull-tab mounting portion 42. Further, by moving the slider 40 toward the upper stopper portion 11 side, the pair of left and right fastener element rows 30 are engaged; by moving the slider 40 to the lower stopper portion 12 side, the pair of left and right fastener element rows 30 are separated. .

Further, as shown in Fig. 1, in the present embodiment, a portion of the warp yarn of the fastener stringer 20 (six in the present embodiment) is used as shown in Fig. 3 in which a wide and wide reflective film 22 is used. And the composite yarn 21 of the light-storing yarn 23. Therefore, since the composite yarn 21 is one yarn, it is not necessary to consider the twist of the reflection film 22 or the like, and the reflection function and the light-storage yarn of the reflection film 22 can be made. 23 The light storage function is stable. Further, the number of used composite yarns 21 is arbitrary. Further, although the composite yarn 21 is used for both the right and left fastener tapes 20, the composite yarn 21 may be used only for one of the fastener chains 20, and the composite yarn 21 may not be used for the other fastener tape 20. .

As shown in FIG. 3, the composite yarn 21 is a composite yarn in which one reflection film 22 and two light-storing yarns 23 are combined, and more specifically, two light-storing yarns 23 are mutually rotated in opposite directions. It is formed by being wound around one reflection film 22.

Further, as shown in FIG. 1, the composite yarn 21 is disposed at a position where the slider 40 does not pass (the position where the movement path of the slider 40 is avoided). Therefore, it is possible to prevent the reflection film 22 having a relatively low strength from being damaged by the movement of the slider 40.

Further, as shown in Fig. 4, a transparent or translucent resin film 24 may be attached to the lower surface of the right and left fastener tapes 20, respectively. By the resin film 24, the lower surface of the fastener tape 20 and the composite yarn 21 can be seen.

As described above, according to the slide fastener 10 of the present embodiment, the composite yarn 21 in which the wide-width reflective film 22 and the light-storing yarn 23 are combined is used in one of the warp yarns of the fastener stringer 20, so that the reflection can be made. The reflection function of the film 22 and the light storage function of the light-storing yarn 23 are stable.

Further, according to the slide fastener 10 of the present embodiment, the composite yarn 21 is formed by winding the two light-storing yarns 23 in the opposite rotation directions on one reflection film 22, and thus the surface of the reflection film 22 is observed from the surface side. In the composite yarn 21, it is possible to observe that the light-storing yarn 23 is hidden on the back side of the reflective film 22, the portion of the reflective film 22 exposed on the surface side, and the light-storing yarn 23 are covered and appear on the surface side of the reflective film 22, The light-storing yarn 23 is exposed on the surface side. Further, the composite yarn 21 is configured such that the reflective film 22 and the light-storing yarn 23 are alternately exposed along the longitudinal direction of the composite yarn 21. Thereby, since the portion of the reflective film 22 and the portion of the light-storing yarn 23 are alternately arranged, both of the composite yarn 21 can obtain both reflectivity and light-storing property.

Further, since the two warp yarns adjacent to the warp yarn of the fastener stringer 20 are woven into the composite yarn 21, the reflection film 22 of one warp yarn is exposed on the surface side and the reflection film of the adjacent warp yarn. 22 is adjacent to the surface side, and it is possible to improve the reflection effect by using two warp yarns, or to expose the portion of the warp reflection film 22 on the surface side and the light-storing yarn 23 of the adjacent warp yarn to the surface side. The portions are adjacent to each other, and the effect of both the reflectivity and the light storage property can be exhibited by the two warp yarns. The portion where the light-storing yarn 23 of one of the warp yarns is exposed on the surface side and the adjacent warp yarns are also the same. Further, in order to exert this effect better, the warp yarns using the composite yarn 21 are preferably three or more adjacent ones, and more preferably four or more. Thereby, the reflectance and the light storage property of the external appearance of the slide fastener 10 can be improved.

Further, the reflection film 22 of the composite yarn 21 is a belt body having a narrow width. When comparing the width dimension and thickness, the width dimension is greater than twice the thickness dimension. Glass beads are attached to one or both sides of the strip. Further, the light-storing yarn 23 of the composite yarn 21 is a multifilament yarn, and a plurality of fibers (Filament) are bundled and twisted to form one multi-fiber yarn. Therefore, it is preferable that all of the plurality of fibers have light storage properties. Further, the cross section of the light-storing yarn 23 is approximately circular, and the cross-sectional dimension of the light-storing yarn 23 is smaller than the width dimension of the reflective film 22, and is larger than the thickness of the reflective film 22. Thereby, both of the reflectability and the light storage property can be obtained more effectively by the one composite yarn 21.

In addition, the present invention is not limited to the above-described embodiments, and can be appropriately modified without departing from the spirit of the present invention.

For example, in the above-described embodiment, the fastener element is a spiral fastener element, but the fastener element is not limited thereto, and may be a metal or resin fastener element.
