These acid components and diol components can be used in combination of plural kinds. Further, a plurality of PBN resins having different compositions may be combined and used. (2. Fiber parts) The fiber parts are explained. Among the components constituting the zipper, the fiber component is not limited, and is a zipper chain cloth, a chain tooth row, a core rope, and a reinforcing chain cloth. There may also be cases where the pull tab is formed by the fiber component. Further, there may be a case where a lanyard such as a rope is attached to the zipper. The zipper chain cloth generally has a sprocket mounting portion on which the side edges of the sprocket rows are attached, and a chain main body portion sewn to the body portion of the article on the opposite side thereof, and the zipper chain can be made by woven or knitted the fibers. cloth. Examples of the fibrous element row include a continuous element row in which a monofilament is formed into a coil shape or a zigzag shape. The core cord is formed by weaving in a side edge along the longitudinal direction of the fastener stringer. By inserting the sprocket into the core rope, the mounting strength of the sprocket can be improved. The core cord may comprise a core yarn and a tubular knit structure covering the periphery thereof. From the viewpoint of making the longitudinal elongation small, the core yarn is preferably used by combining a plurality of untwisted yarns. In order to prevent breakage of the zipper chain cloth, the reinforcing chain cloth may be attached to either or both of the upper end and the lower end of the zipper chain cloth in the width direction of the zipper chain cloth, and may be woven by a plain weave fabric or the like. . The reinforcing chain cloth is effectively attached to the front and back sides of the zipper chain cloth. A configuration example of the core cord 500 is illustrated in FIG. An appropriate number of knitting yarns T (four in the case of the figure) are arranged around the core yarn 501 in the warp direction, and the knitting yarn T is bent into a figure-eight shape along the outer surface of the core yarn 501 in the circumferential direction. In the inverting portion, each of the knitting needle loops L ₁ and L ₂ is produced, and the upper knitting needle loop L _{1 is} sequentially wound around the lower knitting needle loop L ₂ to form a tubular shape around the core yarn 501. Knitting organization. Further, the core yarn 501 can be strongly fastened to the center portion by the knitting needle loops L ₁ , L ₂ and the sinker loops l ₁ and l _{2 of the} tubular knitted structure. Since the fiber component is made of polyethylene terephthalate (PET) resin, it is excellent in dyeability. However, the injection formability of the sprocket when the zipper chain is woven is a problem. In order to perform the injection molding of the fastener elements on the fastener chain cloth, it is necessary to perform the twill on the fastener chain cloth. In general, a polyester zipper fabric uses a plurality of nylon fibers having a high shrinkage ratio as a tightening yarn, and a twill is formed by a heat curing and dyeing step. However, in the case of a fastener chain made of an alcohol polyester, the stretch ratio is hard to be different, so that a straight chain cloth without a twill is formed after heat curing and dyeing. When the twill is not formed or the formation of the twill is insufficient, the core engagement failure occurs when the fastener element is injection-molded, and the yield is remarkably lowered. The present inventors have found that the problem can be solved by reducing the weaving density of the weft yarn when the zipper is woven, thereby improving the stretchability, increasing the number of latitudes of the core rope, and increasing the density and reducing the stretchability. . Generally, in the manufacture of a zipper chain fabric, if it is sufficiently shrunk in the heat curing step after weaving, the chain cloth is slightly elongated in the bath at the time of dyeing. Here, the chain cloth is easily stretched during dyeing by increasing the stretchability of the chain cloth. On the other hand, the core rope is not easily elongated during dyeing because of its high density, thereby forming a twill and forming a chain for injection molding. cloth. However, the range of the weaving density of the chain cloth and the number of latitudes of the core rope which can eliminate the core meshing failure at the same time and the practical strength of the chain cloth are narrow. It is believed that finding such a range of values is also a significant technical contribution to the present invention. Specifically, it is preferable to set the weft density of the weft yarn of the fastener chain cloth to 37 to 43 pieces/inch (2.54 cm), and to set the number of wefts of the core rope to 24 wefts//25.4 mm or more. Alternatively, it is preferable to set the weft density of the weft yarn of the fastener chain cloth to 37 to 39 pieces/inch (2.54 cm), and to set the number of wefts of the core rope to 20 weft rings/25.4 mm or more. By this combination, it is possible to obtain a fastener stringer in which the core engagement is good and the strength is excellent at the time of element ejection molding. More preferably, the weaving density of the weft yarn of the zipper chain cloth is set to 38 to 42 / 吋 (2.54 cm), and the number of latitudes of the core rope is set to 25 latitude / 25.4 mm or more, and more preferably the zipper chain The weft density of the weft yarn of the cloth is set to 38 to 40 pieces/inch (2.54 cm), and the number of wefts of the core rope is set to 25 latitudes//25.4 mm or more. The higher the number of latitudes of the core rope, the easier it is to form a twill, but if it is made too high, the core rope may become hard and the flexibility may be lowered, so that the opening and closing of the slider becomes dull, and so on. It is 30 or less, more preferably 27 or less. Here, the number of latitudes of the core rope refers to the number of stitch rows arranged in the lateral direction of the woven fabric constituting the core rope. The fineness of the yarn constituting the fastener chain cloth may be set to a range used in a general fastener chain cloth. For example, the warp yarn may have a fineness of 75 to 500 dTex, and the weft yarn may have a fineness of 75 to 500 dTex, typically In other words, the warp yarn can be made into a fineness of 100 to 400 dTex, and the weft yarn can be made into a fineness of 100 to 400 dTex. The yarn may be any one of a monofilament and a multifilament, and one yarn may comprise a monofilament or a multifilament obtained by bundling two or more monofilaments, and may further comprise a plurality of multifilaments. For example, a multifilament yarn comprising two monofilaments obtained by bundling 50 monofilaments of 5 dTex is one yarn of 500 dTex. Although depending on the shuttle weaving machine used, the weft yarn generally contains two multifilaments. (3. Injection molding parts) Next, the injection molding parts will be described. Among the components constituting the zipper, there is no limitation on the injection molded component, and it is a slider, a sprocket row, an upper stopper, a lower stopper, and a detachable insert. The slider is used to insert a chain of teeth to control the meshing and separating parts. The upper stop and the lower stop are attached to the upper end or the lower end of the zipper chain to prevent the slider from coming off the part. The detachable insert system generally comprises a pin, a tail cylinder and a pin, and is mounted on the lower end of the zipper chain. In addition to the function of preventing the slider from coming off, the detachable insert has the function of connecting and separating the zipper chain. These are all parts that are conventionally used in zippers. In addition to the above, for example, a pull tab or various decorative articles may be used as the injection molded component. The injection molded part can also be dyed, and for a polyester having poor dyeability like a PTT resin, a pigment can be added to perform injection molding. Further, it is also possible to perform dyeing after injection molding. (4. Other parts) The parts constituting the zipper may be present in addition to the injection molded parts and the fiber parts. For example, a reinforcing chain fabric of a fastener chain can be formed by a transparent film made of polyester. Further, since the adhesive for attaching the reinforcing chain cloth is not a "component" of the zipper, it is not necessarily a polyester-based adhesive. However, from the viewpoint of improving recyclability, it is preferred to use a polyester system. Agent. Examples of the polyester-based adhesive include a thermoplastic polyester-based hot-melt adhesive, ultrasonic welding, and a two-liquid curable adhesive. (5. First embodiment of zipper) Fig. 1 is a front view showing a slide fastener 100 according to a first embodiment of the present invention. The zipper 100 includes a pair of zipper strips 112, a pair of zipper elements 108, a slider 104, a pull tab 102, an upper stop 106, and a detachable insert 110 having a core strand 114 on each side edge of the opposite side. And reinforcing chain cloth 116. The rows of zipper elements 108 are injection molded onto the core strand 114. In the present specification, the slider is configured such that the direction in which the element rows are meshed is slid upward, and the direction in which the element rows are slid is defined as the lower direction. Further, a direction perpendicular to the vertical direction and horizontal to the surface of the fastener stringer is defined as a width direction. Further, a state in which the rows of the fastener elements 108 are attached to each of the fastener chain members 112 is referred to as a fastener chain. Moreover, the pair of zipper chains is referred to as a zipper chain. The fastener chain cloth 112 is woven by a PET resin having a weft density of the weft yarn in the above range. The core cord 114 is formed by coating a PET resin core yarn with a warp-knitted structure made of PET resin, and woven or knitted along the side edges of the fastener chain 112 in the longitudinal direction. On the core cord 114, a zipper element row including a plurality of PTT fastener elements 108 that can be engaged and separated is attached by injection molding. As shown in FIG. 2, the fastener element 108 is injection-molded so that the core cord 114 which knits or woven into the side edge of the fastener tape 112 is clamped from the front surface and the back surface. The dashed line 104 is the imaginary line of the slider. The slider 104 slides on one side of the row in which the fastener elements 108 are inserted, whereby the rows of the pair of fastener elements 108 can be engaged and separated. The slider 104 also includes a pull tab 102 and a pull tab mounting portion 118 for injection molding of the PTT. The upper stop 106 is connected to the upper end of the row of the fastener elements 108, and is fixed to the side edge of the fastener chain by the front and back of the fastener chain. A detachable insert 110 is attached and mounted to the lower end of the row of fastener elements 108. The upper stop 106 and the detachable insert 110 are similarly injection molded parts of the PTT system. The reinforcing chain cloth 116 is a PET resin woven fabric having a plain weave structure, and is attached to the upper end and the lower end of the fastener chain cloth 112 across the front and back sides by using a polyester-based adhesive. (6. Second embodiment of zipper) Fig. 3 is a front view showing a zipper 200 according to a second embodiment of the present invention. The zipper 200 includes a row of coil-shaped fastener elements 208, a fastener chain 212, a slider 204, an upper stop 206, and a lower stop 210. The fastener chain cloth 212 is woven by a PET resin fiber having a weft density of the weft yarn in the above range. The row of the coil-shaped fastener element 208 includes a PET resin monofilament, and is sewn to the side edge portion of the fastener stringer 212 by the PET resin-made sewing yarn 214. The slider 204 slides on one side of the row of the internally inserted fastener elements 208, whereby the rows of the pair of fastener elements 208 can be engaged and separated. The slider 204 also includes a pull tab 202 and a pull tab mounting portion 218 for injection molding of the PTT. The upper stop 206 is connected to the upper end of the row of the fastener elements 108, and the lower stop 210 is connected to the lower end of the row of the fastener elements 208, respectively, by the front and back of the self-zipper chain cloth. The manner in which the stitching line is formed is fixed to the side edge of the zipper chain cloth. Similarly, the upper stopper 206 and the lower stopper 210 are injection molded parts of the PTT system. The zipper of the present invention can be used as an opening and closing member of an article by sewing to various articles. When the zipper of the present invention is used as an opening and closing member for a polyester article, it can be reused for other polyester products without detaching the zipper. Further, the zipper of the present invention can be used not only as an opening and closing member of an article but also as a product other than the opening and closing member such as a rope (for example, a lanyard for a mobile phone). For example, an example of a zipper 300 using the zipper of the present invention is shown in FIG. The rope 300 is formed by forming a row of the PTT fastener elements 308 along the PET core rope 314 so as to sandwich the core rope 314, and then forming the mesh portion of the fastener element at the center portion. In the inner side, the core cord 314 is folded back and aligned at both ends, where the injection molded PTT slider 304 is inserted. Further, the lower end portion is fixed by the injection-molded PTT lower stopper 306 by a polyester-based adhesive, and the PET-made endless rope 310 is formed at the front end of the lower stopper 306. [Examples] Hereinafter, examples for better understanding of the present invention and advantages thereof will be described, but the present invention is not limited to the examples. <1. Evaluation of dyeability> Using the fibers of (1) and (2), a zipper fabric made of a PET resin having a plain weave structure and a PTT resin was woven. (1) PET zipper chain cloth is derived from plant PET resin fiber (Toyota Trading Co., Ltd.) (2) PTT zipper chain cloth is derived from plant PTT resin fiber (Toray Corporation) For these woven zipper chains The cloth was subjected to heat curing at 180 ° C for 90 seconds, and then immersed in a high-pressure dyeing liquid (dispersion dye) having the temperature shown in Table 1 to carry out dyeing for 40 minutes. The dyeing system uses 3 primary colors. The dyeability was evaluated using a CCM (Computer Color Matching System) manufactured by Konica Minolta. The dyeing temperature was set to 130 ° C for zipper dyeing, but it was also tested at 110 ° C for PTT. The dyeing test was performed five times, and the color reproducibility was evaluated based on the color of the first time. The results are shown in Table 1. Since the PTT fiber is dyed from a low temperature, the dyeing speed is fast, so the color change or the color unevenness is large, and the color reproducibility is poor. On the other hand, PET fibers achieve higher color reproducibility. [Table 1] <2. Evaluation of dye fastness> Using the fibers of (1) and (2), a zipper fabric made of a PET resin having a plain weave structure and a PTT resin was woven. (1) PET zipper chain cloth derived from plant PET resin fiber (2) PTT zipper chain cloth Plant-derived PTT resin fiber for these woven zipper chain cloth, dried at 180 ° C The film was thermally cured for 90 seconds, and then immersed in a high-pressure dyeing solution (dispersion dye) having the temperature shown in Table 2, and dyed for 40 minutes. The dyeing system uses black. The dyed fasteners were subjected to a dye fastness test in accordance with JIS L0879:2005. The results are shown in Table 2. In the case where the PLT fiber was used for the zipper chain cloth, in the dye fastness test, the item for the polyester contamination became 1.5 grades, and the quality standard could not be satisfied. However, if the zipper chain cloth is dyed at 130 ° C using PET fibers, it will be 3.5 or more in terms of discoloration fading, cotton contamination, and polyester contamination, and can satisfy the quality standard. [Table 2] <3. Evaluation of Injection Moldability> Using the fibers of the following (1) to (3), the weft density of the weft yarn was changed within the range described in Table 3, thereby woven various zipper fabrics having a plain weave structure. . At this time, according to the test number, a core rope having a different number of wefts is woven on the side edge of the fastener stringer. (1) Normal warp yarn: material PET and nylon, fineness 235-330 dTex, weaving density 42/inch (2.54 cm) Weft: material PET, denier 330 dTex, weaving density core rope as shown in Table 3: <core Yarn>Material PET, 5 untwisted yarns and yam <tubular knit structure>Materials PET, denier 110 dTex, number of wefts recorded in Table 3 (2) PET derived from plants Warp: from plants PET resin fiber, two yarns of 167 dTex, weaving density 40 / 吋 (2.54 cm) Weft: PET resin fiber from plant, two yarns of 167 dTex, as shown in Table 3. Weaving density core rope: <core yarn> from the PET resin fiber of the plant, 8 untwisted yarns and yam <tubular knit structure> plant-derived PET resin fiber, fineness 167 dTex, in Table 3 The number of latitudes recorded (3) is derived from the combination of PET and nylon in plants. The warp yarn is made from plant PET resin, two yarns of 167 dTex, some nylon 235 dTex, and the weaving density is 42/inch ( 2.54 cm) Weft: PET resin fiber from plant, 2 yarns of 167 dTex, weaving as described in Table 3 Core rope: <core yarn> Material: PET resin fiber derived from plants, 8 yarns without twisted yarn <Tubular knit structure> Material: PET resin fiber derived from plants, 2 deniers 167 The yam of dTex, the number of latitudes described in Table 3 for these woven zipper fabrics, heat curing at 180 ° C for 90 seconds, followed by immersion in 130 ° C high pressure dyeing solution (disperse dye) The dyeing was carried out for 40 minutes. The PTT fastener elements are continuously injection-molded along the side edges of the respective zipper chains after dyeing so as to sandwich the core ropes, thereby producing a fastener chain. The results are shown in Table 3. It has been found that by optimizing the number of wefts and the weaving density, even if the fastener stringer made only of the PET resin is formed into a twill, the fastener element can be injection molded at a high yield. [table 3] ○: It can be produced without problems. △: Core meshing defects are rare (more than 5 shots are generated and 300 shots are defective) ×: The core is poorly meshed and the strength is insufficient, so it is impossible to produce (bad within 5 shots) In the evaluation results obtained by the chain tensile strength test, the situation below 350 N is regarded as insufficient strength.
