  Therefore, an object of the present invention is to provide a tape for a slide fastener that uses a warp obtained by winding a film around a core yarn, has a novel appearance, and can enhance fashionability.

  According to the present invention, a tape for a slide fastener formed by weaving warp and weft, and a core part which is an edge part on the side to which a tooth is attached in a width direction perpendicular to the longitudinal direction, and a core part And a main body portion between the core portion and the ear portion, and the main body portion includes a core yarn and a colored film that is spirally wound around the core yarn. There is provided a tape for a slide fastener, comprising at least a plurality of warp yarns.

  In the present invention, a film yarn obtained by spirally winding a colored film around a core yarn is used as the warp of at least a part of the warp group in the main body of the woven fastener tape. Thereby, the colored film part of the film yarn woven as warp in the woven structure of the tape main body part reflects light, and the zipper tape can be given a shiny gloss. In the present invention, the “colored film” refers to a light reflective film that is not colorless and transparent, but is colored and transparent or opaque. Examples of the film material include, but are not limited to, synthetic resins such as polyester resin, polyvinyl chloride, polyethylene, and phenol resin. In the present invention, the film yarn is used as at least a plurality of warps forming the main body of the tape. The film yarn can be used for all warp yarns in the main body of the tape, or can be incorporated every one or more than two warp yarns arranged adjacent to each other in the width direction.

  In the present invention, polyester, nylon, polypropylene, acrylic, and the like can be used as the material for the warp, weft, and core yarn, but are not limited thereto.

  In one embodiment of the present invention, in the film yarn, the core yarn is transparent or white, and the film is wound around the core yarn so as to partially expose the core yarn between one roll of the film. In this case, in the appearance of the film yarn, a portion where a colored film spirally wound around the core yarn appears and a core yarn portion exposed between two turns of the film adjacent to the longitudinal direction of the core yarn, They are arranged alternately in the longitudinal direction of the film yarn. The colored film portion and the transparent or white core yarn exposed portion of the film yarn give contrast and shading to the appearance of the fastener tape between the portion that glitters and the portion that does not shine much.

  In one embodiment of the invention, the weft is a pre-dyed yarn. The pre-dyed yarn is a colored yarn that is dyed before being woven as a fastener tape. By using such a pre-dyed yarn, the appearance of the fastener tape can be given contrast by the film portion (and the exposed portion of the core yarn) of the film yarn as the warp and the colored weft.

  In the present invention, in the main part of the woven fastener tape, as a warp of at least a part of the warp group, by using a film yarn in which a colored film is spirally wound around the core yarn, The colored film portion of the film yarn woven as a warp in the tissue reflects light, and the zipper tape can be given a sparkling appearance.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to these embodiments, and modifications and the like can be appropriately made within the scope of the claims and equivalent scope. FIG. 1 is a plan view showing the slide fastener 1. The slide fastener 1 has a pair of fastener tapes (hereinafter also simply referred to as “tapes”) 10 as slide fastener tapes according to an embodiment of the present invention (hereinafter, left and right and top and bottom are based on the drawing sheet). Is provided. A number of teeth 2 are attached along the longitudinal direction to edge portions (core portions) 11 that face each other in the width direction perpendicular to the longitudinal direction of both tapes 10. Furthermore, the slide fastener 1 includes a slider 3 for engaging and releasing the engagement between the left and right engaging teeth 2, and an upper stopper 4 and a lower stopper 5 for restricting the vertical movement of the slider 3. The slide fastener 1 is configured such that when the user moves the slider 3 upward, the space between the left and right service teeth 2 is closed, and when moved downward, the space between the left and right service teeth 2 is opened.

  FIG. 2 is a partially enlarged view of the fastener tape 10. The tape 10 is formed by weaving warps 20 and wefts 30. As the warp yarn 20, a film yarn 20 (see FIG. 4) described later is used. In the present embodiment, the weft 30 is a single weft 30 formed by combining a plurality of polyester single fiber yarns dyed green before being woven as the tape 10. The tape 10 includes, in the width direction, a core portion 11 that is an edge portion on the side to which the tooth 2 is attached, an ear portion 12 that is an edge portion on the opposite side of the core portion 11, a core portion 11 and an ear portion 12 Between the main body 13 and the main body 13. In order to give the core part 11 strength sufficient for the attachment of the service teeth 2, a core string (not shown) can be woven in the longitudinal direction simultaneously with the weaving of the tape 10. The ear part 12 is an edge part where the weft 30 is folded back, and a fray-preventing ear thread (not shown) can be incorporated in the longitudinal direction. For example, when the slide fastener 1 is attached to clothes, the main body 13 of the tape 10 is sewn to the clothes, and a part of the main body 13 can be seen from the outside of the clothes. Therefore, the main body 13 constitutes a part of the appearance of the garment and affects the fashionability of the garment.

  FIG. 3 is an explanatory view schematically showing the configuration of the woven structure of the film yarn 20 and the weft 30 as the warp 20 of the main body 13. FIG. 4 is a partially enlarged view of the film yarn 20. The film yarn 20 includes a transparent or white core yarn 21 and a colored film 22 wound spirally around the core yarn 21. In the present embodiment, a polyester yarn which is not colored is used as the core yarn 21 of the film yarn 20, and a blue and transparent polyester resin film formed into an elongated strip having a width of about 0.3 mm is used as the film 22. . Such film yarn 20 is a kind of lame yarn called LUREX. In the film yarn 20, the film 22 is wound around the core yarn 21 so that the core yarn 21 is partially exposed between two turns 22 a and 22 b of the film 22 adjacent in the longitudinal direction of the film yarn 20. Thereby, the external appearance of the film yarn 20 includes a blue portion of the film 22 wound around the core yarn 21 and a non-colored portion of the core yarn 21 exposed between the rolls 22 a and 22 b of the film 22. They are arranged alternately in 20 longitudinal directions.

  Referring to FIG. 3 again, in the present embodiment, in the main body 13 of the fastener tape 10, the film yarn 20 and the weft 30 are alternately floated vertically and horizontally (lifted to the front side in FIG. 3) and sinked (same as above). The woven structure to be retracted to the back side is shown. That is, one film yarn 20 repeats ups and downs one by one with respect to the wefts 30 arranged adjacent to each other in the longitudinal direction (the vertical direction in FIG. 3), and another film yarn 20 adjacent to the one film yarn 20 is separated. This one film yarn 20 has the ups and downs with respect to the weft 30 opposite to the one film yarn 20 described above. However, in this embodiment, all the warps constituting the main body portion 13 of the tape 10 are the film 20, but the present invention is not limited to this. For example, every other warp arranged in the width direction, or every two or more warps. One or more film yarns 20 can be incorporated. Thereby, it is possible to give a new appearance to the main body portion 13 of the fastener tape 10 in which the glittering blue portion of the film 22 in the film yarn 20 and the non-lighting portion of the core yarn 21 make a contrast. In addition to this, the green weft 30 shows a novel appearance that has not been seen in the main body 13 of the fastener tape 10. Thereby, the fashionability of the slide fastener 1 can be improved.
