The paper surface of 1 is the back side (the side on the lower side of the slider is not provided with the pull tab), and the upper side is the upper side with respect to the paper surface of Fig. 1 (the side of the direction in which the slider is moved to engage the following element rows) The lower side is the lower side with respect to the paper surface of FIG. 1 (the side on which the moving slider is separated so that the following element rows are separated), the left side is the left side with respect to the paper surface of FIG. 1, and the right side is relative to FIG. The front side of the paper is the front side with respect to the paper surface of Fig. 1, and the lower side is the inner side with respect to the paper surface of Fig. 1, and the front side is the upper side with respect to the paper surface of Fig. 1, the so-called rear side. The paper surface is the lower side with respect to the paper surface of Fig. 1, and the left side is the left side with respect to the paper surface of Fig. 1, and the right side is the right side with respect to the paper surface of Fig. 1. Moreover, the left-right direction of the zipper tape and the slider is also referred to as the width direction. Moreover, the upper and lower directions of the zipper tape are also referred to as the length direction. Further, the length direction of the tape is the longitudinal direction of the fastener tape, and the tape width direction is the width direction of the fastener tape.

As shown in Fig. 1, the slide fastener 10 of the present embodiment includes a pair of left and right fastener tapes 20 which are woven, and a chain of teeth 30 which are respectively disposed on the opposite sides of the pair of right and left fastener tapes 20 The cloth belt side edge portion 20a has a plurality of sprocket teeth 31; the slider 40 is configured to engage and disengage the left and right chain tooth rows 30; and the upper stopper portion 11 is adjacent to the upper end portion of the left and right chain tooth rows 30. And respectively disposed; and the lower stop portion 12 is disposed adjacent to the lower end portion of the left and right element rows 30. Further, by moving the slider 41 to move the slider 40 upward, the left and right element rows 30 can be engaged, and by moving the slider 40 downward, the left and right element rows 30 can be separated.

As shown in FIGS. 2 and 3, the fastener tape 20 is woven by warp yarns 21 and weft yarns 22 of a multifilament yarn comprising polyester fibers or polyamide fibers. The warp yarns 21 and the weft yarns 22 have a fineness of 330 dTex. Further, on both sides of the front side direction of the tape side edge portion 20a of the fastener tape 20 in the front surface direction, core wires 23a, 23b which are disposed adjacent to the warp yarn 21 in the tape width direction and are thicker than the warp yarn 21 are respectively woven. . The core wires 23a and 23b have three multifilament yarns of 560 dTex as a core material, and are covered with a knitting yarn of 267 dTex.

Further, the upper portion of the stopper portion 11 and the lower portion of the lower stopper portion 12 are provided on the side edge portion 20a of the tape side, and the weft yarn 22 and the core wire 23a disposed on the front side are along the tape. A stripe pattern S is formed in the longitudinal direction. Further, the stripe pattern S is formed by making the colors of the weft 22 and the core 23a different from each other. The core wire 23a is disposed closer to the front side of the fastener tape 20 than the front surface of the fastener tape 20. Further, the core wire 23b is disposed closer to the back side of the fastener tape 20 than the back surface of the fastener tape 20. Further, in the present embodiment, the stripe pattern S is formed by the weft yarn 22 and the core wire 23a, but the stripe pattern S may be formed by the warp yarn 21 and the weft yarn 22. Further, as the color of the core wire 23a and the weft yarn 22, for example, when the core wire 23a is made of a light color such as white, the weft yarn 22 is set to a dark color such as brown or dark blue. Further, it is preferable that the color of the warp yarn 21 is the same as the color of the core wire 23a. Therefore, when the color of the core wire 23a is white, the color of the warp yarn 21 is set to white. Further, the color of the warp yarn 21 is not limited to be the same as the color of the core wire 23a, and the color of the warp yarn 21 may be the same as the color of the weft yarn 22, or the color of the warp yarn 21 may be different from the color of the core wire 23a and the weft yarn 22.

Further, in the present embodiment, in order to form a good stripe pattern S, as shown in FIG. 2, the core wire 23a disposed on the front side is crossed by three (in the present embodiment, two yarns are counted as One is woven under the weft yarn 22 and passed under one of the weft yarns 22. Further, the core wire 23b disposed on the back side is woven so as to pass over the one weft yarn 22 and pass under the three weft yarns 22. Further, the warp yarn 21 is woven so as to pass over the two weft yarns 22 and pass under the two weft yarns 22. Therefore, since the core wires 23a, 23b pass over more of the weft yarns 22 than the warp yarns 21 (in the case of the core wires 23b, if they are viewed from the front side of the tape, they pass above the weft yarns 22), the core wires 23a, 23b The degree of exposure becomes large, and a good stripe pattern S is formed. Further, the number of the weft yarns 22 over which the core wire 23a (23b) passes over (through the lower side) is arbitrary, and may be two or more. Further, the weaving method of the warp yarn 21 is a weaving method of the warp yarn 21 adjacent to the core wires 23a and 23b, and the weaving method of the other warp yarns 21 is arbitrary. Further, the stripe pattern may be formed by making the color of the warp yarn 21 different from the weft yarn 22, and the stripe pattern S may be combined with the stripe pattern. Further, since the stripe pattern S is formed along the tape side edge portion 20a by the weft yarns 22 and the core wires 23a having different colors from each other, the color of the weft yarn 22 or the core wire 23a is mounted from the tape side edge portion 20a. The sprocket teeth 31 are exposed. Further, by adjusting at least one of the interval between the stripe pattern S and the interval of the plurality of elements 31, the color exposed from the plurality of elements 31 can be unified into the color of the weft 22 or the core 23a.

As described above, the slide fastener 10 according to the present embodiment has a lower portion of the upper end portion and the lower stopper portion 12 of the stopper portion 11 than the tape side edge portion 20a, along the length of the tape. The stripe pattern S is formed in the direction, so that the appearance of the outer side portions of the stopper portion 11 and the lower stopper portion 12 in the longitudinal direction of the tape can be improved more than the tape side edge portion 20a.

Further, according to the slide fastener 10 of the present embodiment, the stripe pattern S is formed by the weft yarn 22 and the woven hole of the core wire 23a disposed on the front side, and therefore, compared with the case where the stripe pattern is applied to the core wire 23a by coloring, The number of coloring steps can be reduced. Thereby, the manufacturing cost of the zipper 10 can be reduced.

Further, as a first modification of the embodiment, as shown in FIG. 4, the lower stopper portion 12 may be used instead of the opening and closing insert 50 including the tubular pin 51, the open end cylinder 52, and the plug 53. In this case, the stripe pattern S is formed only on the upper side portion of the stopper portion 11 above the tape side edge portion 20a.

Further, as a second modification of the embodiment, as shown in FIG. 5, the pair of right and left fastener element rows 30 can be made of metal, and the pair of left and right fastener elements can be arranged by the first and second sliders 40a and 40b. 30 meshing and separating. The first slider 40a is disposed on the upper side of the slide fastener 10, and the second slider 40b is disposed on the lower side of the slide fastener 10, and is disposed such that the respective rear sides thereof face each other. Further, by moving the first slider 40a upward of the slide fastener 10, the left and right element rows 30 can be meshed, and by moving the first slider 40a downward, the left and right element rows 30 can be separated. Further, by moving the second slider 40b upward of the slide fastener 10, the left and right element rows 30 can be separated, and by moving the second slider 40b downward, the left and right element rows 30 can be engaged. Further, the slide fastener 10 of the present modification includes the upper stopper portion 11 and the lower end portion of the left and right fastener element rows 30 adjacent to the upper end portions of the left and right fastener element rows 30, and the lower stopper portions are respectively disposed. 12. Further, a stripe pattern S is formed along the longitudinal direction of the tape on the lower side portion of the upper end portion of the stopper portion 11 and the lower portion of the lower stopper portion 12 than the tape side edge portion 20a.
