Description

ファスナーストリンガー及びファスナーストリンガーの製造方法Fastener stringer and method of manufacturing fastener stringer
　本発明は、スライドファスナー用ファスナーストリンガー及びその製造方法に関し、特に、ファスナーテープのテープ面に艶を持たせることにより外観品質を向上させたファスナーストリンガー及びその製造方法に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener stringer for a slide fastener and a manufacturing method thereof, and more particularly, to a fastener stringer whose appearance quality is improved by giving gloss to a tape surface of a fastener tape and a manufacturing method thereof.
　例えば衣類の前身頃や開口部などには、スライドファスナーが多く用いられている。スライドファスナーは、一般に、左右一対のファスナーテープの対向するテープ側縁部に、複数のファスナーエレメントを所定の間隔をもって取着することにより、エレメント列が形成された一対のファスナーストリンガーを構成し、更に、得られた一対のファスナーストリンガーのエレメント列にスライダーを摺動可能に取り付けることにより製造される。 For example, slide fasteners are often used for the front and opening of clothing. A slide fastener generally constitutes a pair of fastener stringers in which an element row is formed by attaching a plurality of fastener elements at predetermined intervals to opposite tape side edges of a pair of left and right fastener tapes. The slider is slidably attached to the element row of the obtained pair of fastener stringers.
　また、このようなスライドファスナーは、例えばファスナーテープのテープ主体部を衣類の生地の裏面側に重ねあわせた状態で、テープ主体部と生地とをミシンで縫い合わせることにより衣類に取り付けられる。しかし、スライドファスナーのファスナーテープを、比較的薄くて柔らかな生地に取り付ける場合、ファスナーテープを生地に縫い付けている縫製糸の張力等によって、ファスナーテープに皺が生じることやファスナーテープが波打つことがあり、また、生地の表面にも皺が生じることがあった。 In addition, such a slide fastener is attached to clothing by sewing the tape main portion and the fabric with a sewing machine in a state where the tape main portion of the fastener tape is overlapped with the back side of the clothing fabric. However, when the fastener tape of the slide fastener is attached to a relatively thin and soft fabric, the fastener tape may be wrinkled or the fastener tape may be wavy due to the tension of the sewing thread sewn to the fabric. There were also wrinkles on the surface of the fabric.
　このような問題に対して、例えば特開２００４－６５７４６号公報（特許文献１）には、ファスナーテープに超音波溶着を部分的に施して溶融硬化部を形成することにより、ファスナーテープの剛性が高められたスライドファスナーが開示されている。 For example, Japanese Patent Application Laid-Open No. 2004-65746 (Patent Document 1) addresses such problems by partially applying ultrasonic welding to the fastener tape to form a melt-cured portion, thereby increasing the rigidity of the fastener tape. An elevated slide fastener is disclosed.
　特許文献１に記載されているスライドファスナー７０は、図１２に示したように、ポリエステル等の合成繊維で作られたファスナーテープ７１を有しており、そのファスナーテープ７１の一側縁部には、複数のファスナーエレメント７２が設けられている。 As shown in FIG. 12, the slide fastener 70 described in Patent Literature 1 has a fastener tape 71 made of synthetic fiber such as polyester, and one side edge portion of the fastener tape 71 has a fastener tape 71. A plurality of fastener elements 72 are provided.
　また、ファスナーテープ７１は、超音波溶着により部分的に溶融して硬化した溶融硬化部７３と、溶融硬化されておらず、厚さ寸法が溶融硬化部７３よりも大きな凸部７４とを備えている。この溶融硬化部７３は、テープ幅方向に所定の寸法を有してテープ長さ方向に沿って連続的に設けられている。 The fastener tape 71 includes a melt-cured portion 73 that is partially melted and cured by ultrasonic welding, and a convex portion 74 that is not melt-cured and has a thickness dimension larger than that of the melt-cured portion 73. Yes. The melt-curing portion 73 has a predetermined dimension in the tape width direction and is continuously provided along the tape length direction.
　更に、ファスナーテープ７１の溶融硬化部７３は、一定のパターンで規則正しく設けられており、ファスナーテープ７１には、溶融硬化部７３による均一な模様が、テープ長さ方向に沿って連続して形成されている。このような溶融硬化部７３がファスナーテープ７１のテープ長さ方向に沿って連続的に形成されていることにより、ファスナーテープ７１の剛性が高められたスライドファスナー７０を得ることができる。 Further, the melt-cured portion 73 of the fastener tape 71 is regularly provided in a fixed pattern, and a uniform pattern by the melt-cured portion 73 is continuously formed on the fastener tape 71 along the tape length direction. ing. Since such a melt-cured portion 73 is continuously formed along the tape length direction of the fastener tape 71, the slide fastener 70 in which the rigidity of the fastener tape 71 is increased can be obtained.
　それにより、特許文献１のスライドファスナー７０のファスナーテープ７１を、比較的薄くて柔らかな生地に縫い付ける場合に、ファスナーテープ７１に縫製糸の張力が加えられても、ファスナーテープ７１に皺が生じることやファスナーテープ７１が波打つことを防止でき、スライドファスナー７０を平坦な状態で生地にきれいに取り付けることが可能となる。 Accordingly, when the fastener tape 71 of the slide fastener 70 of Patent Document 1 is sewn to a relatively thin and soft fabric, the fastener tape 71 is wrinkled even if the tension of the sewing thread is applied to the fastener tape 71. And the fastener tape 71 can be prevented from undulating, and the slide fastener 70 can be neatly attached to the fabric in a flat state.
特開２００４－６５７４６号公報JP 2004-65746 A
　現在、スライドファスナーが取り付けられる衣類などのファスナー被着製品には、その用途やデザイン等に応じて様々な材質の生地が用いられている。このようなファスナー被着製品にスライドファスナーを取り付ける場合、ファスナー被着製品の生地にスライドファスナーのファスナーテープを重ね合せた状態で縫製を行うことが一般的である。 Currently, fabrics of fasteners such as clothing to which slide fasteners can be attached use fabrics of various materials depending on the application and design. When attaching a slide fastener to such a fastener-attached product, sewing is generally performed in a state where the fastener tape of the slide fastener is overlapped on the fabric of the fastener-attached product.
　ところで、スライドファスナーのファスナーテープは、通常、ポリエステル繊維を織成又は編成して作られていることが多い。このようなポリエステル繊維を用いて形成されるファスナーテープは、軽くて丈夫であり、皺になり難い等の性質を備えるものの、表面の滑らかさや肌触りに欠けるところがあり、また、テープ表面に例えばナイロン繊維製品に表出するような艶（光沢）が得られない。 By the way, the fastener tape of the slide fastener is usually made by weaving or knitting polyester fiber. Fastener tapes formed using such polyester fibers are light and durable, and have properties such as being hard to become wrinkles, but there are places where the surface is not smooth and soft, and the surface of the tape is, for example, nylon fibers. Gloss (gloss) that appears on the product cannot be obtained.
　このため、スライドファスナーが取り付けられるファスナー被着製品によっては、ファスナー被着製品の生地とファスナーテープとの間で外観上の違和感を生じさせることや異なる感触を生じさせることがあり、更には、ファスナー被着製品のデザイン性を低下させることなどもあったため、ファスナー被着製品のメーカー等からは、ファスナーテープの質感をファスナー被着製品の生地に近付けるように求められることがあった。 For this reason, depending on the fastener-attached product to which the slide fastener is attached, it may cause an unnatural appearance or a different feel between the fabric of the fastener-attached product and the fastener tape. Since the design of the adherend product has been lowered, manufacturers of fastener-attached products have been required to bring the texture of the fastener tape closer to the fabric of the fastener-attached product.
　また、前述の特許文献１に記載されているように、ファスナーテープ７１に超音波溶着を施して、溶融硬化部７３をテープ長さ方向に沿って連続的に形成する場合、テープ表面の滑らかさや肌触りを低下させるとともに、ファスナーテープ７１の柔軟性を低下させるという問題があった。 In addition, as described in Patent Document 1 described above, when ultrasonic welding is performed on the fastener tape 71 and the melt-cured portion 73 is continuously formed along the length direction of the tape, the tape surface is smooth. There was a problem that the touch and the flexibility of the fastener tape 71 were reduced.

Preferably, the tape main body warp has a flatter cross section than the core warp.
　更にこの場合、前記テープ本体経糸における第１テープ面表層部は、テープ表裏方向の反対側に配される第２テープ面表層部よりもテープ幅方向に広く形成されていることが好ましい。更にまた、前記緯糸は、マルチフィラメント糸からなる単糸を２本一組として引き揃えて形成され、２本一組の前記単糸からなる前記緯糸の総繊度は、各テープ本体経糸の総繊度よりも大きく設定されていることが好ましい。 Furthermore, in this case, it is preferable that the first tape surface surface portion of the tape main body warp is formed wider in the tape width direction than the second tape surface surface layer portion arranged on the opposite side of the tape front and back direction. Furthermore, the wefts are formed by drawing two single yarns made of multifilament yarns as a set, and the total fineness of the wefts made of two single yarns is the total fineness of each tape body warp. It is preferable that it is set larger.
　また、本発明のファスナーストリンガーにおいて、前記テープ本体の完全組織は、４つの経糸と４組の緯糸とにより形成され、前記完全組織の一端縁に配される第１経糸は、２／２組織で織り込まれ、前記第１経糸の隣に配される第２経糸は、前記第１経糸に対し、組織点を第１経方向に１つずらした２／２組織で織り込まれ、前記第２経糸の隣に配される第３経糸は、前記第１経糸に対し、組織点を前記第１経方向に３つずらした２／２組織で織り込まれ、前記完全組織の他端縁に配される第４経糸は、前記第１経糸に対し、組織点を前記第１経方向に２つずらした２／２組織で織り込まれていることが好ましい。 In the fastener stringer of the present invention, the complete structure of the tape body is formed by four warps and four sets of wefts, and the first warp arranged at one end edge of the complete structure is a 2/2 structure.

The 4 warp is preferably woven with a 2/2 structure in which the texture point is shifted by two in the first warp direction with respect to the first warp.
　次に、本発明により提供されるファスナーストリンガーの製造方法は、テープ本体の一側縁に芯部が織成一体化されるファスナーテープと、前記ファスナーテープの前記芯部を含むテープ側縁部に所定のピッチで取着される複数のファスナーエレメントとを有するファスナーストリンガーの製造方法であって、前記ファスナーテープを織成する織成工程と、織成された前記ファスナーテープにおける前記芯部を除く前記テープ本体に、加熱加圧処理を行うカレンダー加工工程と、前記加熱加圧処理された前記ファスナーテープの前記テープ側縁部に、複数の前記ファスナーエレメントを取り付けるエレメント取付工程と、を含んでなることを最も主要な特徴とするものである。 Next, the fastener stringer manufacturing method provided by the present invention includes a fastener tape in which a core is woven and integrated with one side edge of the tape body, and a tape side edge including the core of the fastener tape. A method of manufacturing a fastener stringer having a plurality of fastener elements attached at a predetermined pitch, the weaving step of weaving the fastener tape, and excluding the core portion of the woven fastener tape A calendering process for heat-pressing the tape body; and an element attaching process for attaching a plurality of fastener elements to the tape side edge of the heat-pressed fastener tape. Is the most important feature.
　また、本発明の製造方法は、前記エレメント取付工程前に、前記加熱加圧処理された前記ファスナーテープを染色する染色処理工程を含んでいることが好ましい。
　更に、本発明の製造方法は、前記カレンダー加工工程において、織成された前記ファスナーテープを、金属製の加熱ローラーと弾性ローラーとの間に供給して、前記テープ本体を構成する構成糸条の軟化点以下の温度で前記加熱加圧処理を行うことを含んでいることが好ましい。
　更にまた、本発明の製造方法は、前記加熱ローラーとして、周面に前記ファスナーテープの前記芯部を収容するガイド溝が設けられたローラーを用いることを含んでいることが好ましい。 Moreover, it is preferable that the manufacturing method of this invention includes the dyeing | staining process process which dye | stains the said fastener tape by which the said heat-pressing process was carried out before the said element attachment process.
Furthermore, in the production method of the present invention, in the calendering step, the woven fastener tape is supplied between a metal heating roller and an elastic roller, and the constituent yarn constituting the tape body is provided. It is preferable to include performing the heating and pressing treatment at a temperature below the softening point.
Furthermore, it is preferable that the manufacturing method of this invention includes using the roller by which the guide groove which accommodates the said core part of the said fastener tape was provided in the surrounding surface as the said heating roller.
　本発明に係るファスナーストリンガーは、ファスナーテープと、ファスナーテープのテープ側縁部に取着される複数のファスナーエレメントとを有しており、ファスナーテープは、織成されるテープ本体と、そのテープ本体の一側縁に織成一体化される芯部とを有する。 The fastener stringer according to the present invention has a fastener tape and a plurality of fastener elements attached to the side edge of the fastener tape. The fastener tape comprises a woven tape body and the tape body. And a core portion that is woven and integrated with one side edge.
　また、本発明のファスナーストリンガーでは、ファスナーテープにおける芯部を除くテープ本体の全体に対して、例えば金属製の加熱ローラーと弾性ローラーとを用いて、テープ本体を構成する構成糸条の軟化点以下の温度で加熱加圧処理を行うカレンダー加工が施されており、それによって、テープ本体を構成する構成糸条（すなわち、経糸及び緯糸）が、前述の特許文献１のように溶融して硬化することなく、当該構成糸条の加熱ローラーが接する側の第１テープ面が、芯部を構成する構成糸条の外表面よりも平坦化されている。 Further, in the fastener stringer of the present invention, for the entire tape main body excluding the core portion in the fastener tape, for example, using a metal heating roller and an elastic roller, the softening point of the constituent yarn constituting the tape main body or less A calendering process is performed in which a heat and pressure treatment is performed at a temperature of 5 ° C., whereby the constituent yarns (that is, warp yarns and weft yarns) constituting the tape body are melted and cured as in the above-mentioned Patent Document 1. Instead, the first tape surface on the side of the constituent yarn that contacts the heating roller is made flatter than the outer surface of the constituent yarn constituting the core.
　このような本発明のファスナーストリンガーであれば、テープ本体の構成糸条が硬化していないため、ファスナーテープの柔軟性を適切に確保することができる。また、ファスナーテープのテープ本体における第１テープ面が平坦化されているため、従来の一般的なファスナーテープに比べて、第１テープ面の滑らかさや肌触りを向上させることができるとともに、その平坦化された第１テープ面に艶（光沢）を持たせることも可能となる。 In such a fastener stringer of the present invention, since the constituent yarns of the tape body are not cured, the flexibility of the fastener tape can be ensured appropriately. Moreover, since the 1st tape surface in the tape main body of a fastener tape is planarized, while being able to improve the smoothness and touch of a 1st tape surface compared with the conventional general fastener tape, the planarization is also possible. It is also possible to give gloss (gloss) to the first tape surface.
　特に本発明のファスナーストリンガーでは、ファスナーエレメントが取着される前のファスナーテープにおけるテープ本体の全体にカレンダー加工が施されるため、そのカレンダー加工が施されたファスナーテープのテープ側縁部に複数のファスナーエレメントが取着されることによって、テープ側縁部のファスナーエレメント間に露出するテープ部分にも艶を付与することができる。 In particular, in the fastener stringer of the present invention, since the entire tape body of the fastener tape before the fastener element is attached is subjected to calendering, a plurality of tape side edges of the calendered fastener tape are provided. By attaching the fastener elements, it is possible to give gloss to the tape portions exposed between the fastener elements on the side edges of the tape.
　また、本発明のファスナーストリンガーでは、上述のようにカレンダー加工がファスナーテープのテープ本体に施されるものの、ファスナーテープの芯部にはカレンダー加工が意図的に施されていないため、ファスナーテープの芯部が、テープ本体よりもテープ表裏方向に膨出する膨大状の形態を保持する。 Further, in the fastener stringer of the present invention, although the calendering is performed on the tape body of the fastener tape as described above, the core of the fastener tape is not intentionally calendered on the core portion of the fastener tape. The part retains a massive shape that bulges in the tape front and back direction from the tape body.
　このため、カレンダー加工がファスナーテープのテープ本体に施されていても、例えば合成樹脂製のファスナーエレメントを射出成形によってファスナーテープの芯部とテープ本体とを含むテープ側縁部に取着したときに、又は、金属製のファスナーエレメントを加締め加工によってファスナーテープの芯部とテープ本体とを含むテープ側縁部に取着したときに、ファスナーエレメントを、膨大状の芯部を外側から包み込んで把持するようにしてしっかりと取り付けることができる。従って、上述のようにテープ本体の滑らかさや肌触りを向上させると同時に、従来と同程度のファスナーテープに対するファスナーエレメントの高い取付強度を維持することができる。 For this reason, even when calendering is applied to the tape body of the fastener tape, for example, when a synthetic resin fastener element is attached to the tape side edge including the core portion of the fastener tape and the tape body by injection molding Or, when a metal fastener element is attached to the side edge of the tape including the core portion of the fastener tape and the tape main body by caulking, the fastener element is gripped by enclosing the enormous core portion from the outside. It can be attached firmly as you do. Therefore, as described above, the smoothness and feel of the tape body can be improved, and at the same time, the high attachment strength of the fastener element to the fastener tape can be maintained to the same extent as in the past.
　このような本発明のファスナーストリンガーにおいて、ファスナーテープは、テープ本体と芯部とに連続して配される緯糸を有しており、その緯糸は、テープ本体を形成する第１部分（テープ本体形成部）と、芯部を形成する第２部分（芯部形成部）とを有する。更に、この緯糸の第１部分は、第２部分よりも扁平状の横断面を有する。 In such a fastener stringer of the present invention, the fastener tape has a weft thread that is continuously arranged between the tape body and the core, and the weft thread is a first portion that forms the tape body (tape body formation). Part) and a second part (core part forming part) forming the core part. Furthermore, the first portion of the weft has a flatter cross section than the second portion.
　このように、本発明のファスナーストリンガーでは、テープ本体にカレンダー加工が施されることにより、緯糸のテープ本体を形成する第１部分（テープ本体形成部）の横断面が、当該緯糸の芯部を形成する第２部分（芯部形成部）の横断面よりも扁平状に押し潰されて、テープ本体の第１テープ面が平坦化されるため、当該第１テープ面の滑らかさや肌触りを効果的に向上させることができる。 As described above, in the fastener stringer of the present invention, when the tape body is calendered, the cross section of the first portion (tape body forming portion) that forms the tape body of the weft is the core of the weft. Since the first tape surface of the tape body is flattened by being flattened rather than the cross section of the second portion (core portion forming portion) to be formed, the smoothness and feel of the first tape surface are effective. Can be improved.
　また、本発明のファスナーストリンガーにおいて、テープ本体は、緯糸とマルチフィラメント糸からなる複数のテープ本体経糸とにより織成されており、芯部は、緯糸とマルチフィラメント糸からなる複数の芯部経糸とを用いて織成される袋織部と、袋織部内に挿通される芯紐とを備えている。また、テープ本体経糸は、芯部経糸よりも扁平状の横断面を有する。 Further, in the fastener stringer of the present invention, the tape body is woven by a plurality of tape body warps composed of wefts and multifilament yarns, and the core part is composed of a plurality of core part warps composed of wefts and multifilament threads. And a core string inserted into the bag weaving portion. The tape body warp has a flatter cross section than the core warp.
　このように、本発明のファスナーストリンガーでは、テープ本体にカレンダー加工が施されることにより、テープ本体経糸の横断面が芯部経糸の横断面よりも扁平状に押し潰されて、テープ本体の第１テープ面が平坦化されるため、当該第１テープ面の滑らかさや肌触りを効果的に向上させることができる。 As described above, in the fastener stringer of the present invention, the tape body is subjected to calendering, so that the cross section of the tape main body warp is crushed flatter than the cross section of the core warp, and the tape main body Since one tape surface is flattened, the smoothness and feel of the first tape surface can be effectively improved.
　この場合、テープ本体経糸における第１テープ面表層部は、テープ表裏方向の反対側に配される第２テープ面表層部よりもテープ幅方向に広く形成されている。このようにテープ本体経糸の第１テープ面表層部を幅広に形成することにより、テープ本体経糸の第１テープ面をより平坦化させて、滑らかさや肌触りを更に向上させることができるとともに、テープ本体の第１テープ面に艶（光沢）を出し易くすることができる。 In this case, the first tape surface surface layer portion of the tape body warp is formed wider in the tape width direction than the second tape surface surface layer portion arranged on the opposite side of the tape front and back direction. Thus, by forming the first tape surface surface layer portion of the tape main body warp wider, the first tape surface of the tape main body warp can be further flattened, and the smoothness and feel can be further improved. Gloss (gloss) can be easily produced on the first tape surface.
　また、テープ本体経糸の第１テープ面を第２テープ面よりも平坦化させることにより、例えばテープ本体経糸の第１テープ面側と第２テープ面側とを同じように平坦化させる場合に比べて、ファスナーテープが平坦化により硬くなり過ぎることを防止して、ファスナーテープの柔軟性や風合いを適切に確保することができる。 Moreover, compared with the case where the 1st tape surface side of a tape main body warp and the 2nd tape surface side are planarized by making the 1st tape surface of a tape main body warp flatter than a 2nd tape surface, for example. Thus, the fastener tape can be prevented from becoming too hard due to flattening, and the flexibility and texture of the fastener tape can be appropriately ensured.
　上述のような本発明のファスナーストリンガーにおいて、ファスナーテープの緯糸は、マルチフィラメント糸からなる単糸を２本一組として引き揃えて形成されている。また、その２本一組の単糸からなる緯糸の総繊度は、各テープ本体経糸の総繊度よりも大きく設定されている。 In the fastener stringer of the present invention as described above, the weft yarn of the fastener tape is formed by aligning two single yarns made of multifilament yarns as a set. Further, the total fineness of the wefts composed of a set of two single yarns is set to be larger than the total fineness of each tape body warp.
　上述のように緯糸の総繊度が各テープ本体経糸の総繊度よりも大きくなることにより、テープ本体経糸の浮き及び沈み間におけるテープ表裏方向の振幅（クリンプ幅）が大きくなり、テープ本体経糸の緯糸を跨ぐ長さを長く（跨ぐ量を多く）することができる。このため、テープ本体にカレンダー加工を施してテープ本体の第１テープ面を平坦化する際に、緯糸の第１テープ面側に表れるテープ本体経糸をより広く押し潰すことができ、当該緯糸の横断面を扁平状に変形させるとともに、テープ本体経糸の横断面を扁平状の形状に効果的に変形させることができる。またこの場合、テープ本体経糸より第１テープ面側に表れる緯糸も広く押し潰されて、その横断面を扁平状の形状に変形させることができる。 As described above, when the total fineness of the weft is larger than the total fineness of each tape body warp, the amplitude (crimp width) in the tape front and back direction between the float and sink of the tape body warp increases, and the weft of the tape body warp The length of straddling can be increased (the amount of straddling is increased). For this reason, when the tape body is calendered to flatten the first tape surface of the tape body, the tape body warp appearing on the first tape surface side of the weft can be more widely crushed, and the weft crossing The surface can be deformed into a flat shape, and the cross section of the tape main body warp can be effectively deformed into a flat shape. Further, in this case, the wefts appearing on the first tape surface side from the tape main body warp are also crushed widely, and the cross section thereof can be deformed into a flat shape.
　それにより、扁平状に押し潰された緯糸と、その緯糸の第１テープ面側に表れてより扁平状に押し潰されたテープ本体経糸とが相俟って、テープ本体の第１テープ面における滑らかさや肌触りをより効果的に向上させることができ、また、テープ本体の第１テープ面に艶をより効果的に与えることができる。 Thereby, the weft thread crushed flatly and the tape main body warp crushed flattened appearing on the first tape surface side of the weft thread are combined to form the first tape surface of the tape main body. Smoothness and touch can be improved more effectively, and gloss can be more effectively given to the first tape surface of the tape body.
　また、本発明のファスナーストリンガーにおいて、テープ本体の完全組織は、４つの経糸と４組の緯糸とにより形成されている。また、この完全組織の一端縁に配される第１経糸は、２／２組織で織り込まれており、その第１経糸の隣に配される第２経糸は、第１経糸に対し、組織点を第１経方向に１つずらして配置する２／２組織で織り込まれている。更に、第２経糸の隣に配される第３経糸は、第１経糸に対し、組織点を第１経方向に３つずらして配置する２／２組織で織り込まれており、完全組織の他端縁に配される第４経糸は、第１経糸に対し、組織点を第１経方向に２つずらして配置する２／２組織で織り込まれている。 Further, in the fastener stringer of the present invention, the complete structure of the tape body is formed by four warps and four sets of wefts. In addition, the first warp arranged at one end edge of the complete structure is woven in a 2/2 structure, and the second warp arranged next to the first warp is a structure point with respect to the first warp. Are woven in a 2/2 structure that is shifted by one in the first warp direction. Further, the third warp arranged next to the second warp is woven in a 2/2 structure in which the structure point is shifted by three in the first warp direction with respect to the first warp. The fourth warp arranged on the end edge is woven in a 2/2 structure in which the texture points are shifted by two in the first warp direction with respect to the first warp.
　このような織組織を有するテープ本体は、カレンダー加工が施されることにより、テープ本体の第１テープ面をより平坦化できる。また、テープ本体の強度を適切に確保できるとともに、芯部の袋織部の組織を安定させることができ、更には、テープ本体に適度な風合いや柔らかさを与えることも可能となる。 The tape body having such a woven structure can be flattened on the first tape surface of the tape body by calendering. In addition, the strength of the tape main body can be appropriately secured, the structure of the bag woven portion of the core can be stabilized, and further, an appropriate texture and softness can be given to the tape main body.
　次に、本発明に係るファスナーストリンガーの製造方法は、ファスナーテープを織成する織成工程と、織成されたファスナーテープにおける芯部を除くテープ本体の全体に、例えばテープ本体を構成する構成糸条が溶融しない温度（好ましくは軟化しない温度）にて加熱加圧処理を行うカレンダー加工工程と、加熱加圧処理されたファスナーテープのテープ側縁部に、複数のファスナーエレメントを例えば射出成形等により取り付けるエレメント取付工程とを含む。 Next, the method for producing a fastener stringer according to the present invention includes a weaving step of weaving a fastener tape, and the entire main tape body excluding the core portion of the woven fastener tape, for example, constituting yarn constituting the tape body. A plurality of fastener elements are formed by, for example, injection molding on the side edge of the heat-pressed fastener tape by a calendering process in which heat-pressing treatment is performed at a temperature at which the strip does not melt (preferably at a temperature not softening). And an element attaching step for attaching.
　このような本発明の製造方法によれば、テープ本体の構成糸条を硬化させることなく、テープ本体を構成する構成糸条の第１テープ面を、芯部を構成する構成糸条の外表面よりも平坦化することができる。このため、ファスナーテープの柔軟性が適切に確保されており、また、テープ本体の第１テープ面における滑らかさや肌触りが従来の一般的なファスナーテープよりも向上するとともに、その平坦化された第１テープ面に艶を備えたファスナーストリンガーを安定して製造するこができる。 According to such a manufacturing method of the present invention, the first tape surface of the constituent yarn constituting the tape main body is used as the outer surface of the constituent yarn constituting the core portion without curing the constituent yarn of the tape main body. Can be flattened. For this reason, the flexibility of the fastener tape is appropriately ensured, and the smoothness and feel on the first tape surface of the tape body are improved as compared with the conventional general fastener tape, and the flattened first Fastener stringers with gloss on the tape surface can be manufactured stably.
　また、本発明の製造方法によれば、ファスナーテープのテープ本体にカレンダー加工が施されるものの、ファスナーテープの芯部にはカレンダー加工が意図的に施されていないため、芯部が膨大状の形態が保持されたファスナーテープのテープ側縁部にファスナーエレメントをしっかりと強固に取り付けることができ、ファスナーテープに対するファスナーエレメントの高い取付強度を確保することができる。 Further, according to the manufacturing method of the present invention, although the calendering is performed on the tape body of the fastener tape, the core portion of the fastener tape is not intentionally calendered. The fastener element can be firmly and firmly attached to the tape side edge portion of the fastener tape whose shape is held, and high attachment strength of the fastener element to the fastener tape can be ensured.
　このような本発明の製造方法は、エレメント取付工程前に、加熱加圧処理されたファスナーテープを染色する染色処理工程を含む。このような染色処理工程を含むことにより、ファスナーテープに所望の色を容易に着色することができる。また、例えば染色処理工程をカレンダー加工工程の後に行う場合、染色処理工程にてファスナーテープに付与した染料が、カレンダー加工工程の加熱加圧処理で蒸発してファスナーテープの色が薄くなる虞や、ファスナーテープの染色堅牢度が低下する虞があるものの、本発明のようにカレンダー加工工程の後に染色処理工程を行うことにより、ファスナーテープに所望の色彩を安定して付与することができ、また、ファスナーテープの染色堅牢度が低下することも防止できる。 Such a manufacturing method of the present invention includes a dyeing process step of dyeing the heat-pressed fastener tape before the element mounting step. By including such a dyeing | staining process process, a desired color can be easily colored to a fastener tape. In addition, for example, when the dyeing process is performed after the calendering process, the dye applied to the fastener tape in the dyeing process may evaporate due to the heat and pressure treatment of the calendering process, and the color of the fastener tape may be lightened. Although there is a possibility that the dyeing fastness of the fastener tape may be reduced, by performing the dyeing process step after the calendering process as in the present invention, it is possible to stably give a desired color to the fastener tape, It can also prevent the dyeing fastness of the fastener tape from being lowered.
　また、本発明の製造方法は、カレンダー加工工程において、織成されたファスナーテープを、金属製の加熱ローラーと弾性ローラーとの間に供給して、テープ本体を構成する構成糸条の軟化点以下の温度で加熱加圧処理を行うことを含む。それにより、ファスナーテープにおけるテープ本体の第１テープ面を加熱ローラーに接触させて、ファスナーテープを加熱ローラーで所定の温度に加熱しながら、同ファスナーテープを加熱ローラーと弾性ローラーとによりプレスして、テープ本体の構成糸条を溶融させることも軟化させることもなく、テープ本体の加熱ローラーが接する第１テープ面を効率的に平坦化することができる。 Further, in the production method of the present invention, in the calendering process, the woven fastener tape is supplied between the metal heating roller and the elastic roller, and the softening point or less of the constituent yarn constituting the tape body is below. Heating and pressing at a temperature of Thereby, the first tape surface of the tape body in the fastener tape is brought into contact with the heating roller, and the fastener tape is pressed with the heating roller and the elastic roller while heating the fastener tape to a predetermined temperature with the heating roller, The first tape surface with which the heating roller of the tape body contacts can be efficiently flattened without melting or softening the constituent yarns of the tape body.
　更に、本発明の製造方法は、カレンダー加工工程の加熱ローラーとして、周面にファスナーテープの芯部を収容するガイド溝部が設けられたローラーを用いることを含む。これにより、カレンダー加工工程にて、加熱ローラーのガイド溝部にファスナーテープの芯部を収容して案内することが可能となり、それにより、加熱ローラー及び弾性ローラーに対するファスナーテープの位置決めを安定して行うことができるとともに、当該ファスナーテープのテープ本体の全体に、加熱ローラー及び弾性ローラーによる加熱加圧処理を円滑に安定して行うことができる。 Furthermore, the manufacturing method of the present invention includes using a roller provided with a guide groove portion that accommodates the core portion of the fastener tape on the peripheral surface as the heating roller in the calendering process. Thereby, in the calendering process, it becomes possible to accommodate and guide the core portion of the fastener tape in the guide groove portion of the heating roller, thereby stably positioning the fastener tape with respect to the heating roller and the elastic roller. In addition, the heat and pressure treatment with the heating roller and the elastic roller can be smoothly and stably performed on the entire tape body of the fastener tape.

Further, an insertion recess 14e for inserting the shoulder 14d of the fastener element 14 on the mating counterpart side when the left and right fastener elements 14 are meshed is formed at the top (tip) of the meshing head 14a. ing.
　このように、各ファスナーエレメント１４は、前後方向で隣り合うにファスナーエレメント１４に対して、所定の間隔を空けた状態でファスナーテープ２０に固着している。この場合、胴部１４ｃはファスナーテープ２０の表裏面上に配されており、特に、胴部１４ｃは、その噛合頭部１４ａ側とは反対側の端部（テープ内方側端部）がテープ本体２３上に位置するとともに、そのテープ内方側端部から、ファスナーテープ２０の芯部２４の上を通って、ファスナーテープ２０の外側に向けて延出している。そして、ファスナーテープ２０のテープ表面側に配される胴部１４ｃと、ファスナーテープ２０のテープ裏面側に配される胴部１４ｃとは、ファスナーテープ２０から外側に延出した部分にて結合されている。更に、その胴部１４ｃには、首部１４ｂ及び肩部１４ｄが、テープ幅方向の外側に延出するように連続して形成されている。 Thus, each fastener element 14 is fixed to the fastener tape 20 in a state of being spaced apart from the fastener element 14 adjacent to each other in the front-rear direction. In this case, the body portion 14c is arranged on the front and back surfaces of the fastener tape 20, and in particular, the end portion of the body portion 14c opposite to the meshing head portion 14a side (tape inner side end portion) is a tape. It is located on the main body 23 and extends from the inner end of the tape through the core 24 of the fastener tape 20 toward the outside of the fastener tape 20.

Are attached to each other, and the tape side edge 22 of each fastener tape 20 is arranged to face the other fastener stringer 10. .
　この場合、テープ側縁部２２は、ファスナーテープ２０におけるファスナーエレメント１４が固着するテープ幅方向の領域（範囲）であり、ファスナーテープ２０におけるテープ主体部２１との境界部から、噛合相手方のファスナーストリンガー１０に対向するテープ対向側縁（後述する芯部２４側のテープ側縁）までの領域を言う。また、テープ主体部２１は、ファスナーテープ２０におけるテープ側縁部２２との境界部から、上述のテープ対向側縁とは反対側に配されるテープ外方側縁までの領域（範囲）を言う。また、本実施例１のファスナーテープ２０の場合、テープ主体部２１とテープ側縁部２２との境界部は、図４において、芯部２４の隣に配されるテープ本体経糸４２（最も芯部２４側に配されるテープ本体経糸４２）と、当該テープ本体経糸４２の隣に配されるテープ本体経糸４２（芯部２４から２番目に近いテープ本体経糸４２）との間に位置する。 In this case, the tape side edge portion 22 is a region (range) in the tape width direction to which the fastener element 14 of the fastener tape 20 is fixed. From the boundary portion of the fastener tape 20 with the tape main portion 21, the fastener stringer of the mating counterpart 10 is a region up to a tape-facing side edge (a tape side edge on the core 24 side described later) that faces 10. Further, the tape main body 21 refers to a region (range) from the boundary portion of the fastener tape 20 with the tape side edge portion 22 to the tape outer side edge arranged on the side opposite to the above-described tape-opposing side edge. . Further, in the case of the fastener tape 20 of the first embodiment, the boundary between the tape main body 21 and the tape side edge 22 is a tape main body warp 42 (most core part) arranged next to the core part 24 in FIG. 24 and the tape body warp 42 (the tape body warp 42 that is the second closest to the core 24) disposed next to the tape body warp 42.
　また、本実施例１の各ファスナーテープ２０は、テープ主体部２１及びエレメント取付部の一部に亘って所定の厚さ寸法をもって配されるテープ本体２３と、相手方のファスナーストリンガー１０に対向するテープ側縁に沿って配され、テープ本体２３よりもテープ表裏方向に膨出する膨大状の形態を備えた芯部２４とを有する。 Further, each fastener tape 20 of the first embodiment is a tape body 23 arranged with a predetermined thickness dimension over a part of the tape main body 21 and the element mounting portion, and a tape facing the counterpart fastener stringer 10. It has a core portion 24 that is arranged along the side edge and has a massive shape that bulges in the tape front and back direction from the tape main body 23.
　この場合、テープ本体２３と芯部２４との境界部は、図４において、芯部２４の隣に配されるテープ本体経糸４２と、芯部２４の後述する芯紐２６との間に位置し、上述したテープ主体部２１とテープ側縁部２２との境界部よりも芯紐２６に近い位置にある。また、テープ本体２３と芯部２４との境界部は、芯部２４の隣に配されるテープ本体経糸４２と、芯部２４の後述する袋織部２５の最もテープ本体２３側に配される芯部経糸４３との間に位置すると言い換えることもできる。 In this case, the boundary between the tape main body 23 and the core portion 24 is located between the tape main body warp 42 arranged next to the core portion 24 and a core string 26 described later of the core portion 24 in FIG. The core string 26 is closer to the core string 26 than the boundary between the tape main body 21 and the tape side edge 22 described above. Further, the boundary between the tape body 23 and the core portion 24 includes a tape body warp 42 disposed next to the core portion 24 and a core disposed on the tape body 23 side of a bag weaving portion 25 of the core portion 24 which will be described later. It can be paraphrased that it is located between the partial warp yarns 43.
　本実施例１のファスナーテープ２０におけるテープ本体２３は、マルチフィラメント糸からなる２本の単糸を一組として引き揃えて形成される緯糸４１と、マルチフィラメント糸からなる複数のテープ本体経糸４２とを用いて織成されている。また、これらの緯糸４１及びテープ本体経糸４２にはポリエステル繊維が用いられている。 The tape body 23 in the fastener tape 20 of the first embodiment includes a weft 41 formed by aligning two single yarns made of multifilament yarns as a set, and a plurality of tape body warps 42 made of multifilament yarns. It is woven using. Polyester fibers are used for the weft 41 and the tape main body warp 42.
　本実施例１におけるテープ本体２３の織組織では、図４及び図５に示したように、各テープ本体経糸４２が２組の緯糸４１の上側と２組の緯糸４１の下側とを交互に走行する２／２組織で配されており、また、テープ本体経糸４２及び緯糸４１がそれぞれ４本ずつで一つの完全組織４０が作られている。ここで、完全組織とは、経糸と緯糸との組み合わせからなる織組織にて、基本となる組織の最小単位のことを言う。組織点とは、経糸と緯糸とが交差している点を言い、図５の織組織図では、経糸が緯糸の上になって交差する点が塗り潰されている。 In the woven structure of the tape body 23 in the first embodiment, as shown in FIGS. 4 and 5, each tape body warp 42 alternates between the upper side of the two sets of wefts 41 and the lower side of the two sets of wefts 41. It is arranged in a traveling 2/2 structure, and one complete structure 40 is formed by four tape main body warps 42 and four wefts 41 each. Here, the complete structure means a minimum unit of a basic structure in a woven structure composed of a combination of warp and weft. The texture point means a point where the warp and the weft intersect, and in the woven structure diagram of FIG. 5, the point where the warp intersects with the weft is filled.
　特に本実施例１において、テープ本体２３の完全組織４０を形成する４本のテープ本体経糸４２のうち、完全組織４０の一端縁に配される第１経糸は、２／２組織で織り込まれている。また、第１経糸に隣接する第２経糸は、第１経糸に対し、経糸が緯糸の上に交差する組織点（塗り潰された組織点）が前方（第１経方向）に向けて１つずらされた２／２組織で織り込まれており、この第２経糸に隣接する第３経糸は、第１経糸に対し、経糸が緯糸の上に交差する組織点が前方に向けて３つずらされた２／２組織で織り込まれている。更に、完全組織４０の他端縁に配される第４経糸は、第１経糸に対し、経糸が緯糸の上に交差する組織点が前方に向けて２つずらされた２／２組織で織り込まれている。なおこの場合、前方を第１経方向としており、その第１経方向とは反対方向となる後方を、第２経方向と言う。 In particular, in the first embodiment, among the four tape body warps 42 forming the complete structure 40 of the tape body 23, the first warp arranged at one end edge of the complete structure 40 is woven in a 2/2 structure. Yes. Further, the second warp adjacent to the first warp is shifted by one with respect to the first warp, with the texture point (filled texture point) at which the warp intersects with the weft thread shifted forward (first warp direction). The third warp adjacent to the second warp is shifted by three from the first warp to the first warp where the structure point where the warp intersects the weft is forwarded. It is woven in a 2/2 organization. Furthermore, the 4th warp arranged on the other edge of the complete structure 40 is woven with a 2/2 structure in which the structure point where the warp intersects the weft is shifted by two toward the front with respect to the first warp. It is. In this case, the front is defined as the first longitudinal direction, and the rear that is opposite to the first longitudinal direction is referred to as the second longitudinal direction.
　テープ本体２３が上述のような組織で織成されていることにより、テープ本体経糸４２が緯糸４１の上側を走行する部分（織組織図の塗り潰したマス部分）が適度に分散しているため、例えばテープ本体２３が所謂平織組織や綾織組織で織成されている場合に比べて、後述するカレンダー加工がテープ本体２３に施されたときに、テープ本体経糸４２及び緯糸４１を横断面が扁平状となるように押し潰すことで、テープ本体２３の上面（第１テープ面）を効果的に平坦化することができる。これは、上記に表す完全組織４０が４本のテープ本体経糸４２と４組の緯糸４１で構成されることにより達成される。 Since the tape main body 23 is woven with the above-described structure, the portion where the tape main body warp 42 runs on the upper side of the weft 41 (the mass portion filled in the woven structure diagram) is appropriately dispersed. For example, compared to the case where the tape body 23 is woven in a so-called plain weave structure or twill structure, when the calendering which will be described later is applied to the tape body 23, the transverse cross section of the tape body warp 42 and weft 41 is flat. The upper surface (first tape surface) of the tape body 23 can be effectively flattened by crushing so that This is achieved by the complete structure 40 described above being composed of four tape body warps 42 and four sets of wefts 41.
　更に、上述のような織組織を有するテープ本体２３は、完全組織４０を形成する４本のテープ本体経糸４２の組織点をバランス良くずらして形成されている。このため、テープ強度を適切に確保できるとともに、芯部２４の袋織部２５の組織を安定させることができる。更に、テープ本体２３に適度な風合いや柔らかさを与えることも可能となる。 Furthermore, the tape body 23 having the woven structure as described above is formed by shifting the texture points of the four tape body warps 42 forming the complete structure 40 in a balanced manner. For this reason, while ensuring tape strength appropriately, the structure | tissue of the bag weave part 25 of the core part 24 can be stabilized. Furthermore, it is possible to give the tape main body 23 an appropriate texture and softness.
　なお、本発明においては、テープ本体２３の織組織は上述のものに限定されるものではなく、例えばテープ本体経糸４２の一部又は全部の組織を２／２組織から１／１組織に変更して、テープ本体２３の一部又は全部の領域を、テープ本体経糸４２と緯糸４１が交互に浮き沈みする平織組織で形成しても良く、また、テープ本体２３の一部又は全部の領域を綾織組織で形成しても良い。 In the present invention, the woven structure of the tape body 23 is not limited to the one described above. For example, a part or all of the structure of the tape body warp 42 is changed from 2/2 structure to 1/1 structure. Thus, a part or all of the tape body 23 may be formed of a plain weave structure in which the tape body warps 42 and wefts 41 are alternately raised and sinked, and a part or all of the tape body 23 is formed of a twill weave structure. May be formed.

The weft 41 has a first part (tape body forming part) 41a that forms the tape body 23 and a second part (core part forming part) 41b that forms the core part 24. In this case, the first portion 41a of the weft 41 is in a region from the boundary between the tape main body 23 and the core portion 24 to the tape outer side edge disposed on the side opposite to the tape facing side edge of the fastener tape 20. The second portion 41 b of the weft 41 is a portion disposed in a region from the boundary between the tape main body 23 and the core portion 24 to the tape facing side edge of the fastener tape 20.
　言い換えると、緯糸４１はファスナーテープ２０の全体に一続きに配されているとともに、緯糸４１の第１部分４１ａがテープ本体経糸４２とともにテープ本体２３の織組織を形成し、その第１部分４１ａよりも芯部２４側に配される第２部分４１ｂが、後述する芯部経糸４３とともに芯部２４の袋織部２５を形成している。 In other words, the weft threads 41 are arranged continuously throughout the fastener tape 20, and the first portion 41a of the weft threads 41 forms a woven structure of the tape body 23 together with the tape body warp threads 42. Also, the second portion 41b arranged on the core portion 24 side forms a bag weave portion 25 of the core portion 24 together with a core portion warp 43 described later.
　この場合、緯糸４１を形成する各単糸の総繊度は、１６０ｄｔｅｘ以上３４０ｄｔｅｘ以下に設定されており、各単糸を形成するフィラメントの本数は、７２本以上１４４本以下に設定されている。つまり、単糸を２本一組にして形成される緯糸４１の総繊度は、３２０ｄｔｅｘ以上６８０ｄｔｅｘ以下に設定されており、緯糸４１の全体を形成するフィラメントの本数は、１４４本以上２８８本以下に設定されている。特に本実施例１の場合では、緯糸４１の全体の総繊度が６８０ｄｔｅｘ（各単糸の総繊度が３４０ｄｔｅｘ）で、緯糸４１の全体を形成するフィラメントの本数が１９２本（各単糸のフィラメントの本数が９６本）に設定されている。なお、本発明において、緯糸４１の総繊度及びフィラメントの本数は特に限定されず、任意に変更することが可能である。 In this case, the total fineness of each single yarn forming the weft 41 is set to 160 dtex or more and 340 dtex or less, and the number of filaments forming each single yarn is set to 72 or more and 144 or less. That is, the total fineness of the wefts 41 formed as a pair of two single yarns is set to 320 dtex or more and 680 dtex or less, and the number of filaments forming the entire weft 41 is 144 to 288. Is set. In particular, in the case of Example 1, the total fineness of the entire weft 41 is 680 dtex (the total fineness of each single yarn is 340 dtex), and the number of filaments forming the entire weft 41 is 192 (the filaments of each single yarn). The number is 96). In the present invention, the total fineness of the weft 41 and the number of filaments are not particularly limited and can be arbitrarily changed.
　一方、本実施例１の各テープ本体経糸４２における総繊度は、緯糸４１の各単糸の総繊度以上であり、且つ、１６０ｄｔｅｘ以上５００ｄｔｅｘ以下に設定されている。また、各テープ本体経糸４２を形成するフィラメントの本数は、緯糸４１の各単糸を形成するフィラメントの本数以上であり、且つ、７２本以上１８０本以下に設定されている。特に本実施例１の場合では、テープ本体経糸４２の総繊度が５００ｄｔｅｘで、緯糸４１を形成するフィラメントの本数は１４４本に設定されている。 On the other hand, the total fineness of each tape main body warp 42 of the first embodiment is equal to or greater than the total fineness of each single yarn of the weft 41 and is set to 160 dtex or more and 500 dtex or less. The number of filaments forming each tape main body warp 42 is equal to or more than the number of filaments forming each single yarn of the weft 41 and is set to 72 or more and 180 or less. Particularly in the case of Example 1, the total fineness of the tape main body warp 42 is 500 dtex, and the number of filaments forming the weft 41 is set to 144.
　なお、緯糸４１は、上述のように２本一組の単糸により形成されていることから、一組の緯糸４１の総繊度は、テープ本体経糸４２の総繊度よりも大きく設定され、且つ、一組の緯糸４１の全体を形成するフィラメントの本数は、テープ本体経糸４２を形成するフィラメントの本数より多く設定される。 Since the weft 41 is formed by a set of two single yarns as described above, the total fineness of the set of wefts 41 is set larger than the total fineness of the tape main body warp 42, and The number of filaments forming the entire set of wefts 41 is set to be larger than the number of filaments forming the tape main body warp 42.
　また本実施例１において、緯糸４１のテープ本体２３に配される第１部分４１ａと、各テープ本体経糸４２とは、後述する加熱ローラー５１及び弾性ローラー５２によるカレンダー加工がテープ本体２３に施されている。このため、緯糸４１の第１部分４１ａ及びテープ本体経糸４２における糸の長手方向に直交する横断面の形状は、緯糸４１の芯部２４に配される第２部分４１ｂと、ファスナーテープ２０の芯部２４に配される後述の芯部経糸４３とに比べて、細長い扁平状の形態を有するとともに、テープ本体２３の加熱ローラー５１が接する上面が平坦化されている。 In the first embodiment, the first portion 41a of the weft 41 arranged on the tape body 23 and each tape body warp 42 are calendered by the heating roller 51 and the elastic roller 52, which will be described later, on the tape body 23. ing. For this reason, the shape of the cross section orthogonal to the longitudinal direction of the first portion 41a of the weft 41 and the tape main body warp 42 is the second portion 41b arranged in the core portion 24 of the weft 41 and the core of the fastener tape 20. Compared with a core warp 43 (described later) disposed in the portion 24, the upper surface of the tape body 23 with which the heating roller 51 is in contact is flattened, as well as having an elongated flat shape.
　特に本実施例１では、２本一組の単糸により形成される緯糸４１の総繊度が、上述のようにテープ本体経糸４２の総繊度よりも大きく設定されているとともに、同緯糸４１におけるフィラメントの本数は、テープ本体経糸４２におけるフィラメントの本数より多い。この場合、緯糸４１が太くなるとともに、テープ本体経糸４２におけるテープ表裏方向の振幅が大きくなるため、テープ本体経糸４２が緯糸４１の上面側を跨ぐ量を多くすることができる。 In particular, in the first embodiment, the total fineness of the weft 41 formed by a set of two single yarns is set to be larger than the total fineness of the tape main body warp 42 as described above, and the filament in the weft 41 is the same. Is larger than the number of filaments in the tape main body warp 42. In this case, since the weft 41 becomes thicker and the amplitude of the tape body warp 42 in the tape front and back direction increases, the amount of the tape body warp 42 straddling the upper surface side of the weft 41 can be increased.
　これにより、テープ本体２３にカレンダー加工を施したときに、緯糸４１のテープ本体２３に配される第１部分４１ａがテープ長さ方向に押し潰されるとともに、緯糸４１の上面側を跨ぐテープ本体経糸４２の部分がテープ幅方向へより広く押し潰されて、テープ本体経糸４２の横断面を、図６に示すように扁平状の形状にすることができる。なお、図６では、１６７ｄｔｅｘ当たりにおけるテープ本体経糸４２の断面を模式的に表している。また、緯糸４１の第１部分４１ａの横断面は、図面に表されていないものの、テープ長さ方向へ細長く押し潰された扁平状の形状を呈し、特に、テープ本体経糸４２の上面側を跨ぐ緯糸４１の横断面は、より細長い扁平状の形状を呈する。 Thus, when the tape body 23 is calendered, the first portion 41a of the weft 41 placed on the tape body 23 is crushed in the tape length direction and the tape body warp straddling the upper surface side of the weft 41. The portion 42 is crushed more widely in the tape width direction, and the cross section of the tape main body warp 42 can be made flat as shown in FIG. In addition, in FIG. 6, the cross section of the tape main body warp 42 per 167 dtex is typically represented. Further, although the cross section of the first portion 41a of the weft 41 is not shown in the drawing, it exhibits a flat shape that is squeezed and elongated in the tape length direction, and particularly straddles the upper surface side of the tape main body warp 42. The cross section of the weft 41 has a more elongated flat shape.
　従って、本実施例１のファスナーテープ２０では、２本一組の単糸からなる緯糸４１の押し潰された第１部分４１ａと、その緯糸４１の第１部分４１ａの上面側を跨いでより扁平状に押し潰されたテープ本体経糸４２とが相俟って、テープ本体２３のテープ上面を平坦化し、当該テープ上面における滑らかさや肌触りを効果的に向上させることができる。 Therefore, in the fastener tape 20 of the first embodiment, the flattened portion straddles the first portion 41a crushed by the weft 41 composed of a set of two single yarns and the upper surface side of the first portion 41a of the weft 41. The tape main body warp 42 crushed in a shape can be combined to flatten the tape upper surface of the tape main body 23, and the smoothness and feel on the tape upper surface can be effectively improved.
　また、テープ本体２３の上面が平坦になることによって、テープ本体２３の上面へ入射した光を、平坦化される前のテープ上面に比べて多く反射させて、その反射光（拡散光）を強くすることができるため、テープ本体２３の上面に艶を効果的に与えることができる。 Further, since the upper surface of the tape main body 23 becomes flat, the light incident on the upper surface of the tape main body 23 is reflected more than the upper surface of the tape before being flattened, and the reflected light (diffused light) is strengthened. Therefore, gloss can be effectively given to the upper surface of the tape body 23.
　更にこの場合、各テープ本体経糸４２においては、カレンダー加工において後述する加熱ローラー５１が接触するテープ上面側の表層部（第１テープ面表層部）が、その上面側表層部とはテープ表裏方向の反対側に位置するテープ下面側の表層部（第２テープ面表層部）よりも、テープ幅方向に広く押し潰されており、テープ上面側の表層部における幅方向の寸法が、テープ下面側の表層部における幅方向の寸法よりも大きくなる。 Furthermore, in this case, in each tape main body warp 42, the surface layer portion (first tape surface surface layer portion) on the upper surface side of the tape with which the heating roller 51 described later in calendar processing comes into contact, the upper surface surface layer portion is in the tape front and back direction. It is crushed wider in the tape width direction than the surface layer portion (second tape surface surface layer portion) on the tape lower surface side located on the opposite side, and the dimension in the width direction in the surface layer portion on the tape upper surface side is It becomes larger than the dimension of the width direction in a surface layer part.
　上述のような断面形状を各テープ本体経糸４２が有することにより、例えばテープ本体経糸４２のテープ下面側の表層部もテープ上面側の表層部と同じようにテープ幅方向に広く押し潰される場合に比べて、ファスナーテープが硬くなり過ぎることを防止し、ファスナーテープの柔軟性や風合いを適切に確保することができる。またこの場合、テープ上面側の表層部に配されるフィラメントは、カレンダー加工で押し潰されることにより、円形ではない異形断面を備えることもある。 When each tape body warp 42 has the cross-sectional shape as described above, for example, when the surface layer portion on the tape lower surface side of the tape body warp 42 is crushed widely in the tape width direction in the same manner as the surface layer portion on the tape upper surface side. In comparison, the fastener tape can be prevented from becoming too hard, and the flexibility and texture of the fastener tape can be ensured appropriately. In this case, the filament disposed on the surface layer portion on the upper surface side of the tape may be provided with a non-circular cross section by being crushed by calendering.
　更に、例えば芯部２４に配される後述の芯部経糸４３の断面を図７に模式的に表すように、ファスナーテープ２０の芯部２４にはカレンダー加工が施されていないため、芯部経糸４３は略円形状の横断面を有しており、特に、芯部経糸４３の外側に露呈する表面（外表面）は円弧状に形成されている。また、芯部経糸４３を形成するフィラメント間に生じる間隙が比較的大きくなる。 Further, for example, as shown schematically in FIG. 7 in a cross section of a later-described core warp 43 arranged on the core 24, the core 24 of the fastener tape 20 is not calendered. 43 has a substantially circular cross section, and in particular, the surface (outer surface) exposed to the outside of the core warp 43 is formed in an arc shape. Further, the gap generated between the filaments forming the core warp 43 becomes relatively large.
　また、緯糸４１の芯部２４に配される第２部分４１ｂの横断面は、図面に表されていないものの、この第２部分４１ｂには芯部経糸４３と同様にカレンダー加工が施されていないため、略円形状を呈するとともに、第２部分４１ｂの外側に露呈する表面（外表面）は円弧状に形成されている。すなわち、緯糸４１の横断面は、テープ本体２３にテープ本体経糸４２と織り込まれる第１部分４１ａではテープ長さ方向に細長い扁平形状を有するとともに、一方、芯部２４の袋織部２５に芯部経糸４３と織り込まれる第２部分４１ｂでは、外表面が円弧状となる略円形状を有する。 Further, although the cross section of the second portion 41b arranged in the core portion 24 of the weft 41 is not shown in the drawing, the second portion 41b is not calendered in the same manner as the core portion warp 43. Therefore, while exhibiting a substantially circular shape, the surface (outer surface) exposed to the outside of the second portion 41b is formed in an arc shape. That is, the cross section of the weft 41 has a flat shape elongated in the tape length direction in the first portion 41 a woven with the tape main body warp 42 in the tape main body 23, while the core portion warp in the bag weaving portion 25 of the core portion 24. The second portion 41b woven with 43 has a substantially circular shape whose outer surface is arcuate.
　従って、このような緯糸４１の第２部分４１ｂや芯部経糸４３に対して、カレンダー加工が施されたテープ本体２３における緯糸４１の第１部分４１ａやテープ本体経糸４２は上述のような扁平状の横断面を有しており、特に、このテープ本体経糸４２のテープ上面は、芯部経糸４３の円弧状の外表面よりも平坦化されている。また、テープ本体経糸４２を形成するフィラメント同士が密着してフィラメント間に生じる間隙が小さくなっており、テープ本体経糸４２におけるフィラメントの密度が高められている。 Therefore, the first portion 41a of the weft 41 and the tape main body warp 42 in the tape body 23 subjected to the calendar processing with respect to the second portion 41b and the core portion warp 43 of the weft 41 are flat as described above. In particular, the tape upper surface of the tape body warp 42 is flattened more than the arcuate outer surface of the core warp 43. Further, the filaments forming the tape main body warp 42 are in close contact with each other, and the gap generated between the filaments is reduced, and the density of the filaments in the tape main body warp 42 is increased.
　本実施例１におけるファスナーテープ２０の芯部２４は、芯紐２６が袋織部２５内に挿入されて保持されて形成されている。また、袋織部２５は、テープ本体２３から連続して配される緯糸４１と、ポリエステルのマルチフィラメント糸からなる複数の芯部経糸４３とを用いて、袋状の二重織組織（袋織組織）で織成されている。なお本実施例１では、複数の芯部経糸４３のうちの一部の芯部経糸４３にナイロン繊維を用いることも可能である。 The core portion 24 of the fastener tape 20 in the first embodiment is formed by holding the core string 26 inserted into the bag weaving portion 25. Further, the bag weaving portion 25 uses a weft 41 continuously arranged from the tape body 23 and a plurality of core warps 43 made of polyester multifilament yarns, thereby forming a bag-like double woven structure (bag weaving structure). Is woven. In the first embodiment, it is also possible to use nylon fibers for some core warps 43 among the plurality of core warps 43.
　本実施例１の芯紐２６は、引き揃えられた複数本のマルチフィラメントからなる芯糸を、複数の編糸で編成される外周編成層で包み込むことにより形成されている。このような芯紐２６はニットコードと呼ばれることもある。なお本発明において、芯紐２６の構成は限定されるものではなく、任意に変更することができる。例えば複数のフィラメントが並列状に引き揃えられたものを芯紐２６として袋織部２５内に保持することも可能である。 The core string 26 of the first embodiment is formed by wrapping core yarns composed of a plurality of aligned multifilaments in an outer knitting layer knitted with a plurality of knitting yarns. Such a core string 26 is sometimes called a knit cord. In the present invention, the configuration of the core string 26 is not limited and can be arbitrarily changed. For example, a filament in which a plurality of filaments are arranged in parallel can be held in the bag weaving portion 25 as a core string 26.
　本実施例１の袋織部２５を形成する複数の芯部経糸４３は、内部に芯紐２６を包み込むようにして、１／３，３／１組織で織り込まれている。なお、袋織部２５を形成する芯部経糸４３の本数は、芯紐２６の太さに応じて任意に変更することができる。また、芯部経糸４３は、１／４，４／１組織で織り込まれていても良い。 The plurality of core warps 43 forming the bag weaving portion 25 of Example 1 are woven in a 1/3, 3/1 structure so as to wrap the core string 26 inside. In addition, the number of the core part warp 43 which forms the bag weave part 25 can be arbitrarily changed according to the thickness of the core string 26. The core warp 43 may be woven in a 1/4, 4/1 structure.
　それぞれの芯部経糸４３は、上述したテープ本体経糸４２と同じ総繊度を有するとともに、各芯部経糸４３を形成するフィラメントの本数も、上述したテープ本体経糸４２と同じ本数に設定されている。また、芯部経糸４３は、カレンダー加工が施されないため、上述したように、芯部経糸４３は略円形状の横断面を有しており（図７を参照）、また、芯部経糸４３を形成するフィラメント間には、テープ本体経糸４２を形成するフィラメント間に生じる間隙よりも大きな間隙が生じている。 Each core warp 43 has the same total fineness as the above-described tape body warp 42, and the number of filaments forming each core warp 43 is also set to the same number as the above-described tape body warp 42. Further, since the core warp 43 is not subjected to calendering, as described above, the core warp 43 has a substantially circular cross section (see FIG. 7). A gap larger than the gap generated between the filaments forming the tape main body warp 42 is formed between the formed filaments.
　上述のような芯部経糸４３を有する袋織部２５内にニットコードの芯紐２６が保持されて芯部２４が形成されていることにより、芯部２４の膨大状の形態を安定させることができる。また、芯部２４には後述するカレンダー加工が施されないため、芯部２４の形態が押し潰されることもない。このため、ファスナーエレメント１４を、芯部２４をしっかりと包み込むようにしてファスナーテープ２０に強固に固着させることができる。 Since the core portion 24 is formed by holding the core cord 26 of the knit cord in the bag woven portion 25 having the core portion warp 43 as described above, the enormous form of the core portion 24 can be stabilized. . In addition, since the core part 24 is not subjected to calendar processing described later, the form of the core part 24 is not crushed. For this reason, the fastener element 14 can be firmly fixed to the fastener tape 20 so as to firmly wrap the core portion 24.
　次に、上述のような本実施例１のファスナーストリンガー１０を製造する方法について、図８に示したフロー図を参照しながら説明する。
　先ず、ファスナーテープ２０を織成する織成工程を行う。このファスナーテープ織成工程では、織機を用いて、テープ本体２３と芯部２４とを備えるファスナーテープ２０を、上述した所定の組織となるように織成する。 Next, a method for manufacturing the fastener stringer 10 of the first embodiment as described above will be described with reference to the flowchart shown in FIG.
First, a weaving process for weaving the fastener tape 20 is performed. In this fastener tape weaving step, the fastener tape 20 including the tape main body 23 and the core portion 24 is woven using a loom so as to have the above-described predetermined structure.
　ファスナーテープ２０の織成工程後、得られたファスナーテープ２０に加熱加圧処理を施すカレンダー加工工程を行う。加熱加圧処理とは、ファスナーテープ２０に対して熱を加えながら、ファスナーテープ２０の上下方向の寸法を非加圧時よりも小さくなるように圧力を加える処理である。 After the weaving process of the fastener tape 20, a calendering process is performed in which the obtained fastener tape 20 is heated and pressurized. The heating and pressurizing process is a process of applying pressure to the fastener tape 20 so that the vertical dimension of the fastener tape 20 becomes smaller than that when no pressure is applied while applying heat to the fastener tape 20.
　このカレンダー加工工程に用いられる加熱加圧処理装置５０は、図９に示すように、スチールなどの金属で形成される加熱ローラー５１と、加熱ローラー５１に対応して配される弾性ローラー５２と、加熱ローラー５１及び弾性ローラー５２間にファスナーテープ２０を供給する図示しないテープ供給部と、加熱ローラー５１及び弾性ローラー５２の下流側に配され、ファスナーテープ２０を回収する図示しないテープ回収部とを有する。 As shown in FIG. 9, the heat and pressure treatment apparatus 50 used in this calendering process includes a heating roller 51 formed of a metal such as steel, an elastic roller 52 arranged corresponding to the heating roller 51, and A tape supply unit (not shown) that supplies the fastener tape 20 between the heating roller 51 and the elastic roller 52 and a tape recovery unit (not shown) that is arranged on the downstream side of the heating roller 51 and the elastic roller 52 and collects the fastener tape 20. .
　なお、本実施例１の加熱加圧処理装置５０において、加熱ローラー５１及び弾性ローラー５２は、各ローラー５１，５２の回転軸方向の寸法が大きく確保され、複数のファスナーテープ２０に対して同時に加熱加圧処理が可能なように形成されている。 In the heat and pressure treatment apparatus 50 according to the first embodiment, the heating roller 51 and the elastic roller 52 have a large dimension in the rotation axis direction of each of the rollers 51 and 52, and heat the plurality of fastener tapes 20 simultaneously. It is formed so that it can be pressurized.
　加熱加圧処理装置５０の加熱ローラー５１は、搬送されるファスナーテープ２０の一方のテープ面（テープ上面）側に回転可能に配されている。また、この加熱ローラー５１は、ローラー自体の温度を制御することができ、ファスナーテープ２０を所望の温度に加熱することができる。 The heating roller 51 of the heating and pressurizing apparatus 50 is rotatably arranged on one tape surface (tape upper surface) side of the fastener tape 20 to be conveyed. Moreover, this heating roller 51 can control the temperature of the roller itself, and can heat the fastener tape 20 to a desired temperature.
　また、加熱ローラー５１のローラー周面部は、図１０に示すように、ファスナーテープ２０のテープ本体２３を加圧する平滑な加圧面５１ａと、ファスナーテープ２０の芯部２４に対応する位置に凹設されたガイド溝５１ｂとを有しており、ガイド溝５１ｂは、１本のファスナーテープ２０に対して１つの割合で加熱ローラー５１に設けられている。 Further, as shown in FIG. 10, the roller circumferential surface portion of the heating roller 51 is recessed at a position corresponding to the smooth pressure surface 51 a that presses the tape body 23 of the fastener tape 20 and the core portion 24 of the fastener tape 20. The guide groove 51b is provided in the heating roller 51 at a ratio of one to the fastener tape 20.
　加熱加圧処理装置５０の弾性ローラー５２は、金属製の芯金部５２ａと、芯金部５２ａの周りに配され、弾性を備える合成樹脂又はエラストマーからなる弾性層５２ｂとを有する。また、弾性ローラー５２のローラー周面部は、加熱ローラー５１の加圧によって、図１０に示すように、ファスナーテープ２０を介して押されて形成される僅かな窪み５２ｃを有する。なお、本発明では、弾性ローラー５２として、ペーパーローラーやコットンローラーを用いても良い。 The elastic roller 52 of the heat and pressure treatment apparatus 50 has a metal cored bar 52a and an elastic layer 52b made of a synthetic resin or elastomer having elasticity and disposed around the cored bar 52a. Further, the roller peripheral surface portion of the elastic roller 52 has a slight recess 52c formed by being pressed through the fastener tape 20 as shown in FIG. In the present invention, a paper roller or a cotton roller may be used as the elastic roller 52.
　上述のような加熱ローラー５１及び弾性ローラー５２を有する加熱加圧処理装置５０を用いて、ファスナーテープ２０にカレンダー加工を行う場合、加熱ローラー５１を所定の温度まで加熱するとともに加熱ローラー５１及び弾性ローラー５２を所定の速度で回転させ、その回転する加熱ローラー５１及び弾性ローラー５２間に向けて、図示を省略したテープ供給部からファスナーテープ２０を供給する。 When calendering is performed on the fastener tape 20 using the heating and pressing apparatus 50 having the heating roller 51 and the elastic roller 52 as described above, the heating roller 51 and the elastic roller are heated while heating the heating roller 51 to a predetermined temperature. 52 is rotated at a predetermined speed, and the fastener tape 20 is supplied from a tape supply unit (not shown) toward the rotating heating roller 51 and elastic roller 52.
　このとき、ファスナーテープ２０のテープ本体２３が、加熱ローラー５１の加圧面５１ａと弾性ローラー５２との間に通されることにより、加熱ローラー５１によりテープ本体２３（特にテープ本体２３の上面）が加熱されながら、同テープ本体２３が加熱ローラー５１及び弾性ローラー５２によりテープ表裏方向にプレスされる。また、ファスナーテープ２０の芯部２４は、テープ本体２３が加熱ローラー５１及び弾性ローラー５２間を通過する際に、加熱ローラー５１のガイド溝５１ｂに挿入されて収容される。 At this time, the tape body 23 of the fastener tape 20 is passed between the pressure surface 51 a of the heating roller 51 and the elastic roller 52, whereby the tape body 23 (particularly the upper surface of the tape body 23) is heated by the heating roller 51. The tape main body 23 is pressed in the tape front and back direction by the heating roller 51 and the elastic roller 52. Further, the core 24 of the fastener tape 20 is inserted and accommodated in the guide groove 51 b of the heating roller 51 when the tape main body 23 passes between the heating roller 51 and the elastic roller 52.
　これにより、芯部２４が加熱ローラー５１及び弾性ローラー５２によって加圧されることを回避できるとともに、加熱ローラー５１及び弾性ローラー５２に対してファスナーテープ２０を所定の位置に案内し、ファスナーテープ２０の位置決めを容易に行うことができる。このため、ファスナーテープ２０の芯部２４を除くテープ本体２３の全体に対して、加熱加圧処理を安定して施すことができる。 Thereby, while being able to avoid that the core part 24 is pressurized by the heating roller 51 and the elastic roller 52, the fastener tape 20 is guided to a predetermined position with respect to the heating roller 51 and the elastic roller 52, and the fastener tape 20 Positioning can be performed easily. For this reason, the heat and pressure treatment can be stably applied to the entire tape body 23 excluding the core portion 24 of the fastener tape 20.
　この場合、加熱ローラー５１によるファスナーテープ２０の加熱温度は、緯糸４１及びテープ本体経糸４２を形成するポリエステル繊維の軟化点以下の温度に設定されており、例えば本実施例１では、ファスナーテープ２０の加熱温度が１９５℃に設定されている。なお本発明において、例えばファスナーテープ２０を構成する構成糸条が複数の材料で形成されている場合、加熱ローラー５１によるファスナーテープ２０の加熱温度は、それらの構成糸条における最も低い軟化点以下の温度に設定される。 In this case, the heating temperature of the fastener tape 20 by the heating roller 51 is set to a temperature equal to or lower than the softening point of the polyester fiber forming the weft 41 and the tape body warp 42. For example, in the first embodiment, the fastener tape 20 The heating temperature is set to 195 ° C. In the present invention, for example, when the constituent yarn constituting the fastener tape 20 is formed of a plurality of materials, the heating temperature of the fastener tape 20 by the heating roller 51 is equal to or lower than the lowest softening point in those constituent yarns. Set to temperature.
　ファスナーテープ２０の加熱温度が上述のように設定されることにより、テープ本体２３の緯糸４１及びテープ本体経糸４２が溶融することや互いに融着することを防止し、ファスナーテープ２０の適切な柔らかさや風合いを維持することができる。なお、テープ本体２３のテープ上面を効率的に平坦化するために、ファスナーテープ２０の加熱温度は１５０℃以上に、特に１７０℃以上に設定されることが好ましい。 By setting the heating temperature of the fastener tape 20 as described above, it is possible to prevent the weft 41 and the tape body warp 42 of the tape body 23 from being melted or fused to each other. The texture can be maintained. In order to efficiently flatten the upper surface of the tape of the tape body 23, the heating temperature of the fastener tape 20 is preferably set to 150 ° C. or higher, particularly 170 ° C. or higher.
　なお本実施例１において、ファスナーテープ２０を構成する糸はポリエステル糸であり、その融点は２３０℃である。軟化点とは、融点よりも低い温度であり、フィラメント糸が軟らかくなって、フィラメント糸の形状が元の形状に比べて変化する温度を言う。また、マルチフィラメント糸からなるファスナーテープ２０の構成糸条に、上述のような加熱加圧処理が施されることにより、構成糸条を形成する各フィラメントの断面形状は変形し難いものの、複数のフィラメントからなる構成糸条全体の横断面は、外側に露呈する糸条表面が円弧状に形成される略円形状の状態から、糸条表面が比較的平らになる扁平状の状態に変形する。 In Example 1, the yarn constituting the fastener tape 20 is a polyester yarn, and its melting point is 230 ° C. The softening point is a temperature lower than the melting point, and refers to a temperature at which the filament yarn becomes soft and the shape of the filament yarn changes compared to the original shape. Moreover, although the cross-sectional shape of each filament which forms a constituent yarn is hard to change by performing the above-mentioned heat-pressing process to the constituent yarn of the fastener tape 20 which consists of multifilament yarns, The entire cross section of the constituent yarn composed of filaments is deformed from a substantially circular shape in which the yarn surface exposed to the outside is formed in an arc shape into a flat shape in which the yarn surface is relatively flat.
　以上のようなカレンダー加工工程がファスナーテープ２０に行われることにより、ファスナーテープ２０の芯部２４の形態を維持しながら、ファスナーテープ２０のテープ本体２３が加熱加圧処理され、それにより、同テープ本体２３のテープ本体経糸４２の横断面と緯糸４１の第１部分４１ａの横断面とが扁平状に変形して、加熱ローラー５１が接するテープ本体２３の上面が平坦化される。 By performing the calendering process as described above on the fastener tape 20, the tape body 23 of the fastener tape 20 is heated and pressurized while maintaining the form of the core portion 24 of the fastener tape 20. The cross section of the tape main body warp 42 of the main body 23 and the cross section of the first portion 41a of the weft 41 are deformed into a flat shape, and the upper surface of the tape main body 23 with which the heating roller 51 contacts is flattened.
　特に上述のように、テープ上面（第１テープ面）に接する加熱ローラー５１と、テープ下面（第２テープ面）に接する弾性ローラー５２とを用いてカレンダー加工を行うことにより、ファスナーテープ２０に適切な圧力を加えて加熱加圧処理を円滑に行うことができる。また、加熱ローラー５１側のテープ上面表層部を、弾性ローラー５２側のテープ下面表層部よりも、テープ幅方向に広く押し潰すことができ、テープ本体２３のテープ上面をより効果的に平坦化することができる。 Particularly suitable for the fastener tape 20 by calendering using the heating roller 51 in contact with the upper surface of the tape (first tape surface) and the elastic roller 52 in contact with the lower surface of the tape (second tape surface) as described above. It is possible to smoothly perform the heating and pressurizing process by applying an appropriate pressure. Moreover, the tape upper surface portion on the heating roller 51 side can be crushed wider in the tape width direction than the tape lower surface portion on the elastic roller 52 side, and the tape upper surface of the tape body 23 is more effectively flattened. be able to.
　また、テープ本体２３のテープ下面も加熱加圧処理前に比べると平坦化されるが、テープ下面は加熱ローラー５１と接していないため、テープ本体２３のテープ上面のような艶は表れ難い。このように、テープ本体２３のテープ上面とテープ下面との見た目が異なるようにすることで、このファスナーテープ２０を衣服などに縫い付ける際に、作業者がファスナーストリンガー１０の表裏方向を誤って縫い付けることを防止できる。なお本発明では、テープ本体２３のテープ上面とテープ下面の両面にカレンダー加工を行って、上下両面とも平坦化することも可能である。 Further, although the lower surface of the tape of the tape body 23 is flattened as compared with that before the heating and pressurizing treatment, the lower surface of the tape is not in contact with the heating roller 51, so that the gloss like the upper surface of the tape of the tape body 23 hardly appears. Thus, by making the appearance of the tape upper surface and the tape lower surface of the tape main body 23 different, when the fastener tape 20 is sewn to clothes or the like, the operator erroneously sews the front and back directions of the fastener stringer 10. Can be prevented. In the present invention, the upper and lower surfaces can be flattened by calendering both the upper surface and the lower surface of the tape body 23.
　更にこの場合、例えばテープ回収部等によって、加熱加圧処理されるファスナーテープ２０の加熱ローラー５１及び弾性ローラー５２の位置よりも下流側の部分（すなわち、加熱加圧処理されたテープ部分）を、加熱ローラー５１及び弾性ローラー５２の位置よりも上流側の部分（すなわち、加熱加圧処理される前のテープ部分）に与えられる張力よりも大きな張力で引っ張りながら加熱加圧処理を行うことも可能である。それにより、ファスナーテープ２０を加熱ローラー５１及び弾性ローラー５２に対して滑らすようにしながら押圧して、テープ本体２３のテープ上面をより安定して効率的に平坦化することが可能となる。 Furthermore, in this case, for example, by a tape recovery unit or the like, a portion on the downstream side of the position of the heating roller 51 and the elastic roller 52 of the fastener tape 20 to be heated and pressed (that is, the tape portion subjected to the heating and pressing process) It is also possible to perform the heat and pressure treatment while pulling with a tension larger than the tension applied to the portion upstream of the position of the heating roller 51 and the elastic roller 52 (that is, the tape portion before the heat and pressure treatment). is there. As a result, the fastener tape 20 is pressed against the heating roller 51 and the elastic roller 52 while being slid, and the upper surface of the tape of the tape body 23 can be more stably and efficiently flattened.
　次に、上述の加熱加圧処理されたファスナーテープ２０に対して染色処理工程を行う。この染色処理工程において、ファスナーテープ２０を染色処理する具体的な方法は特に限定されないが、例えばファスナーテープ２０を染色ビームに巻き付けて、その染色ビームを所定の温度に加熱された染色液中に所定時間浸漬することにより、ファスナーテープ２０を高温状態で染色することができる。 Next, a dyeing process is performed on the above-described fastener tape 20 that has been subjected to the heat and pressure treatment. In this dyeing process, a specific method for dyeing the fastener tape 20 is not particularly limited. For example, the fastener tape 20 is wound around a dyeing beam, and the dyeing beam is heated in a dyeing solution heated to a predetermined temperature. By soaking for a long time, the fastener tape 20 can be dyed in a high temperature state.
　このようにカレンダー加工工程後に染色処理工程を行うことによって、ファスナーテープ２０に所望の色を安定して着色でき、また、例えば染色処理工程後にカレンダー加工工程が行われる場合のように、染料が蒸発してファスナーテープ２０の色が薄くなることや、ファスナーテープ２０の染色堅牢度が低下することを防止できる。 By performing the dyeing process after the calendering process in this manner, the desired color can be stably colored on the fastener tape 20, and for example, the dye evaporates as in the case where the calendering process is performed after the dyeing process. As a result, it is possible to prevent the color of the fastener tape 20 from being lightened and the dyeing fastness of the fastener tape 20 from being lowered.
　上述の染色処理工程を行った後、染色したファスナーテープ２０を、テープ長さ方向に所定の大きさの張力を加えた状態で保持して、同ファスナーテープ２０における芯部２４とテープ本体２３の芯部２４側の側縁部とにより形成されるテープ側縁部２２に、熱可塑性樹脂の射出成形を行って、所定の形状を有する複数のファスナーエレメント１４を形成する射出成形工程（エレメント取付工程）を行う。 After performing the above-described dyeing process, the dyed fastener tape 20 is held in a state where a predetermined amount of tension is applied in the tape length direction, and the core portion 24 and the tape body 23 of the fastener tape 20 are retained. An injection molding process (element mounting process) in which a plurality of fastener elements 14 having a predetermined shape are formed by performing injection molding of a thermoplastic resin on the tape side edge 22 formed by the side edge on the core 24 side. )I do.
　このとき、ファスナーエレメント１４が成形されるファスナーテープ２０では、テープ本体２３の芯部２４側の側縁部まで加熱加圧処理が施されて平坦化されているものの、芯部２４には加熱加圧処理が施されておらず、膨大状の芯部２４の形態が維持され、また、芯部２４に配置される緯糸４１の第２部分４１ｂ及び芯部経糸４３の風合いが残っている。このため、当該ファスナーテープ２０のテープ側縁部２２に射出成形を行うことにより、ファスナーエレメント１４を、テープ側縁部２２に、芯部２４をしっかりと包み込むようにして固着させることができる。 At this time, in the fastener tape 20 in which the fastener element 14 is molded, the side edge on the side of the core 24 of the tape body 23 is heated and flattened to be flattened. Pressure processing is not performed, the form of the enormous core part 24 is maintained, and the texture of the second portion 41b of the weft 41 and the core part warp 43 that are arranged in the core part 24 remains. For this reason, by performing injection molding on the tape side edge portion 22 of the fastener tape 20, the fastener element 14 can be fixed to the tape side edge portion 22 so as to firmly wrap the core portion 24.
　以上の工程を経て製造されるファスナーストリンガー１０は、ファスナーテープ２０のテープ側縁部２２にファスナーエレメント１４がしっかりと取着されており、また、ファスナーテープ２０の柔軟性が適切に確保されているとともに、テープ本体２３のテープ上面が平坦化されている。 In the fastener stringer 10 manufactured through the above steps, the fastener element 14 is firmly attached to the tape side edge portion 22 of the fastener tape 20, and the flexibility of the fastener tape 20 is appropriately secured. At the same time, the tape upper surface of the tape body 23 is flattened.
　このため、ファスナーテープ２０のテープ本体２３のテープ上面における滑らかさや肌触りを、例えばテープ本体２３のテープ下面よりも向上させることができ、更には、テープ本体２３のテープ上面に、従来の織成ファスナーテープでは得られなかった艶（光沢）を表出させることができる。 For this reason, the smoothness and the touch on the tape upper surface of the tape main body 23 of the fastener tape 20 can be improved, for example, compared with the tape lower surface of the tape main body 23. Furthermore, the conventional woven fastener is provided on the tape upper surface of the tape main body 23. Gloss (gloss) that could not be obtained with tape can be expressed.
　特に本実施例１のファスナーストリンガー１０では、ファスナーテープ２０のテープ側縁部２２を形成するテープ本体２３も平坦化されているため、ファスナーテープ２０のテープ長さ方向で互いに隣接するファスナーエレメント１４間に露呈するテープ部分にも、艶を表出させることができ、ファスナーストリンガー１０の品質を高めることができる。 In particular, in the fastener stringer 10 of the first embodiment, the tape body 23 that forms the tape side edge portion 22 of the fastener tape 20 is also flattened, and therefore, between the fastener elements 14 adjacent to each other in the tape length direction of the fastener tape 20. Also, the gloss can be exposed to the tape portion exposed to the tape, and the quality of the fastener stringer 10 can be improved.
　そして、上述のように製造されたファスナーストリンガー１０に対し、仕上げ工程として、ファスナーストリンガー１０を２つ一組で組み合わせて、その一組のファスナーストリンガー１０のエレメント列１１にスライダー３０を取り付けることや、一組のファスナーストリンガー１０に止具１２及び開離嵌挿具１３を形成すること等の作業を行うによって、図１に示したスライドファスナー１が製造される。 For the fastener stringer 10 manufactured as described above, as a finishing process, two fastener stringers 10 are combined in pairs, and the slider 30 is attached to the element row 11 of the pair of fastener stringers 10, The slide fastener 1 shown in FIG. 1 is manufactured by performing operations such as forming the stopper 12 and the separation / insertion insertion tool 13 on the set of fastener stringers 10.
　このように製造された本実施例１のスライドファスナー１（ファスナーストリンガー１０）は、従来では得られなかったファスナーテープ２０のテープ上面における滑らかさや肌触り等の質感を備えるとともに、艶又は光沢を備えている。従って、本実施例１のスライドファスナー１が衣類や鞄類などのファスナー被着製品に取り付けられたときに、ファスナーテープ２０の外観をファスナー被着製品の質感やデザインに適切に合わせることや、また、ファスナー被着製品の外観品質を従来よりも向上させることが可能となるため、スライドファスナー１の商品価値を大きく高めることができる。 The slide fastener 1 (fastener stringer 10) of Example 1 manufactured as described above has a texture such as smoothness and feel on the upper surface of the fastener tape 20 that has not been obtained conventionally, and also has gloss or gloss. Yes. Therefore, when the slide fastener 1 of the first embodiment is attached to a fastener-attached product such as clothing or groceries, the appearance of the fastener tape 20 is appropriately matched to the texture and design of the fastener-attached product, Since the appearance quality of the fastener-attached product can be improved as compared with the prior art, the commercial value of the slide fastener 1 can be greatly increased.
　なお、上述した実施例１では、ファスナーテープ２０の織成工程の後に、ファスナーテープ２０に加熱加圧処理を施すカレンダー加工を行うことによって、ファスナーテープ２０におけるテープ本体２３のテープ上面（第１テープ面）を平坦化している。しかし、本発明はこれに限定されるものではなく、例えば上述のカレンダー加工工程において、２段階の加熱加圧処理を行って、ファスナーテープ２０におけるテープ本体２３のテープ上面とテープ下面の両方を平坦化することが可能である。 In Example 1 mentioned above, after the weaving process of the fastener tape 20, the upper surface of the tape main body 23 in the fastener tape 20 (first tape) is performed by performing a calendering process that heats and pressurizes the fastener tape 20. Surface) is flattened. However, the present invention is not limited to this. For example, in the calendering process described above, two stages of heating and pressing are performed to flatten both the upper surface and the lower surface of the tape main body 23 of the fastener tape 20. It is possible to
　具体的に説明すると、実施例１において詳述したファスナーテープ２０に対する上記加熱加圧処理を第１加熱加圧処理とする。そして、その第１加熱加圧処理を行った後に、テープ本体２３のテープ上面が平坦化されたファスナーテープ２０に対して、ファスナーテープ２０におけるテープ本体２３のテープ下面（第２テープ面）が加熱ローラー５１に接するようにして、第１加熱加圧処理と同じ処理条件で第２加熱加圧処理を施す。 More specifically, the above-described heat and pressure treatment for the fastener tape 20 described in detail in Example 1 is referred to as a first heat and pressure treatment. And after performing the 1st heat pressurization process, the tape lower surface (2nd tape surface) of the tape main body 23 in the fastener tape 20 is heated with respect to the fastener tape 20 in which the tape upper surface of the tape main body 23 was planarized. The second heat and pressure treatment is performed under the same processing conditions as the first heat and pressure treatment so as to contact the roller 51.
　これによって、ファスナーテープ２０におけるテープ本体２３のテープ上面とテープ下面の両面を平坦化することができるため、テープ本体２３におけるテープ上面及びテープ下面の両面の滑らかさや肌触りを向上させるとともに、その両面に艶又は光沢を与えることが可能となる。
　更に本発明では、必要に応じて、ファスナーテープ２０に撥水剤を塗布する撥水加工を行うことも可能である。 As a result, both the upper surface and the lower surface of the tape main body 23 of the tape main body 23 of the fastener tape 20 can be flattened, so that the smoothness and feel of both the upper surface and the lower surface of the tape main body 23 can be improved. Gloss or gloss can be imparted.
Furthermore, in this invention, it is also possible to perform the water repellent process which applies a water repellent to the fastener tape 20 as needed.
　また上述した実施例１では、ファスナーテープ２０の芯部２４が、芯紐２６を袋織部２５内に挿入して保持することによって形成されているが、本発明において、ファスナーテープにおける芯部の形態はこれに限定されず、ファスナーテープのテープ本体に対してテープ表裏方向に膨出する膨大状の形態であれば、その構造を変更することができる。 Moreover, in Example 1 mentioned above, although the core part 24 of the fastener tape 20 is formed by inserting and holding the core string 26 in the bag weaving part 25, in this invention, the form of the core part in a fastener tape However, the structure is not limited to this, and the structure can be changed as long as it has a huge shape that bulges in the tape front and back direction with respect to the tape body of the fastener tape.
　例えば、実施例１の変形例に係るファスナーテープの織組織を図１１に模式的に示すように、このファスナーテープ２０ａの芯部２４ａは、テープ本体２３から連続する緯糸４１の第２部分４１ｂで、ニットコードの形態を有する芯紐２６を織り込んで保持することにより形成されている。すなわち、この変形例に係る芯部２４ａには、前述の実施例１における芯部２４のような芯部経糸４３が配されておらず、袋織部２５が形成されていない。 For example, as schematically shown in FIG. 11 of the woven structure of the fastener tape according to the modified example of the first embodiment, the core portion 24a of the fastener tape 20a is a second portion 41b of the weft 41 continuous from the tape body 23. It is formed by weaving and holding a core string 26 having the form of a knit cord. That is, the core part 24a according to this modification is not provided with the core part warp 43 like the core part 24 in the first embodiment, and the bag weaving part 25 is not formed.
　この変形例に係る芯部２４ａを備えたファスナーテープ２０ａを用いて形成されるファスナーストリンガー１０ａも、前述の実施例１の場合と同様のカレンダー加工が施されているため、前述の実施例１に係るファスナーストリンガー１０と同様の効果が得られる。 Since the fastener stringer 10a formed by using the fastener tape 20a provided with the core portion 24a according to this modification is also subjected to the same calendering process as in the case of the above-described first embodiment, The same effect as the fastener stringer 10 can be obtained.
　更にこの変形例に係るファスナーテープ２０ａでは、１本の芯紐２６を緯糸４１の第２部分４１ｂで保持することによって芯部２４ａが形成されているが、本発明では、例えば２本の芯紐をファスナーテープの第１テープ面（上面）側と第２テープ面（下面）側のそれぞれに配置して、これら２本の芯紐をそれぞれテープ本体から連続する緯糸の第２部分で織り込んで保持することによって、ファスナーテープの芯部を形成することもできる。 Furthermore, in the fastener tape 20a according to this modification, the core portion 24a is formed by holding one core string 26 by the second portion 41b of the weft 41. In the present invention, for example, two core strings are used. Are arranged on the first tape surface (upper surface) side and the second tape surface (lower surface) side of the fastener tape, respectively, and these two core cords are woven and held by the second portion of the weft continuous from the tape body. By doing so, the core part of a fastener tape can also be formed.
