Description

導電配線及びその製造方法Conductive wiring and its manufacturing method
　本発明は、導電配線及びその製造方法に関する。 The present invention relates to a conductive wiring and a method for manufacturing the same.
　従来から固定電話と受話器を繋ぐカールコードは、螺旋状であることで動きに対しての追従性が良く、導電線が断線され難いことが知られている。また伸縮する芯に導電線や導電繊維を螺旋状に巻き付けることで配線のたるみを少なくし取り回しを良くしたものがある。
　しかし、螺旋状配線は、螺旋方向と逆へ捻じれた場合に構造が崩れ、配線が絡まる問題がある。さらに芯となるものに導電線や導電繊維を巻き付けた螺旋構造では、擦れや伸縮で芯と螺旋構造の位置がズレ動いて分離し断線する問題がある為、螺旋構造全体を覆うように外側が樹脂・チューブ・組み物で被覆され、内部構造が露出しないように加工して扱いやすくする必要がある。しかし、これら配線は外径が大きくなり構造が硬くなるので、配線の曲げ難さや捻じり難さ、伸縮率の低下が発生し追従性能を阻害する問題が生じる。
　一方、血圧、脈拍等を測定する器具を組み込んだ、いわゆるウエアラブル衣料等には、血圧、脈拍等を測定する器具と、この器具から取り出したデータを外部に送るための通信手段とを導通するための導電糸又は導電材料が使用される。特許文献１には、導電糸としては、カーボン系の導電糸、金属又は合金のめっき糸、導電性樹脂繊維糸、金属繊維糸等が提案されている。特許文献２には、導電性カーボン微粒糸を練り込んだナイロン糸が提案されている。特許文献３には、ポリエステルフィルムの表面に金、銀などの金属を蒸着した金属蒸着フィルムをスリットした糸が提案されている。特許文献４にはウエアラブル衣類に使用する電極として、可撓性電極が提案されている。 It has been known that the curled cord that connects a landline telephone and a handset has a spiral shape that allows it to easily follow movements, and that the conductive wire is less likely to break. There are also devices that reduce slack in the wiring and improve handling by wrapping conductive wires or conductive fibers in a spiral around an expandable core.
However, when the spiral wiring is twisted in the opposite direction to the spiral direction, the structure collapses and the wiring becomes tangled. Furthermore, with a helical structure in which a conductive wire or conductive fiber is wrapped around a core, there is a problem that the position of the core and the helical structure may shift due to rubbing or expansion and contraction, resulting in separation and breakage. It is covered with resin, tubes, and braiding, and must be processed so that the internal structure is not exposed to make it easier to handle. However, since the outer diameter of these wirings becomes large and the structure becomes hard, problems arise in that the wirings are difficult to bend and twist, and the expansion/contraction rate is reduced, which impairs tracking performance.
On the other hand, so-called wearable clothing that incorporates devices that measure blood pressure, pulse, etc., has a built-in device that connects the device that measures blood pressure, pulse, etc. with a communication means to send the data extracted from the device to the outside. conductive threads or conductive materials are used. Patent Document 1 proposes carbon-based conductive yarns, metal or alloy plated yarns, conductive resin fiber yarns, metal fiber yarns, and the like as conductive yarns. Patent Document 2 proposes a nylon thread kneaded with conductive carbon fine threads. Patent Document 3 proposes a thread obtained by slitting a metal-deposited film in which metals such as gold and silver are deposited on the surface of a polyester film. Patent Document 4 proposes a flexible electrode as an electrode for use in wearable clothing.

　しかし、従来の金属配線は生地との追従が乏しく、使い勝手が良くないという問題があった。 However, conventional metal wiring has a problem in that it does not follow the fabric well and is not easy to use.
　本発明は、前記従来の問題を解決するため、生地との追従が良好であり、余分なたるみがなく、キンクも起こらず、使い勝手が良い導電配線を提供する。 In order to solve the above-mentioned conventional problems, the present invention provides conductive wiring that follows the fabric well, does not sag, does not cause kinks, and is easy to use.
　本発明の導電配線は、コイル状電線と、チェーンステッチ糸を含み、前記チェーンステッチ糸は連続して環縫いされており、前記導電線は前記チェーンステッチ糸の環内に縫い留まっており、前記導電線と前記チェーンステッチ糸は一体化されていることを特徴とする。  The conductive wiring of the present invention includes a coiled electric wire and a chain stitch thread, the chain stitch thread is continuously chain-stitched, the conductive wire is sewn and secured within the ring of the chain stitch thread, and the It is characterized in that the conductive wire and the chain stitch thread are integrated.​

　本発明は、コイル状電線と、チェーンステッチ糸を含む導電配線である。コイル状電線は、例えば固定電話の本体と受話器の間に接続されているカールコードとして使われている。本発明のコイル状電線は、カールコードだけでなく、これより太くてもよいし細くてもよく、コイル形状も任意のものを使用できる。チェーンステッチは、環縫いによって形成でき、経編みの基本である鎖編みも含む。前記チェーンステッチ糸は連続して環縫いされており、導電線はチェーンステッチ糸の環内に縫い留まっており、前記導電線と前記チェーンステッチ糸は一体化されている。チェーンステッチ糸の環内に縫い留まっているとは、コイル状電線はチェーンステッチ糸に包含され組み込まれていることをいう。これにより、コイル状電線は生地との追従が良好であり、余分なたるみがなく、キンクも起こらず、使い勝手が良い導電配線となる。 The present invention is a conductive wiring including a coiled electric wire and a chain stitch thread. Coiled wires are used, for example, as curled cords connected between the body of a landline telephone and the handset. The coiled electric wire of the present invention is not limited to a curled cord, but may be thicker or thinner than this, and any coil shape can be used. Chain stitch can be formed by chain stitching, and includes chain stitch, which is the basis of warp knitting. The chain stitch thread is continuously chain-stitched, the conductive wire is sewn into the ring of the chain stitch thread, and the conductive wire and the chain stitch thread are integrated. Sewn within the loop of chain stitch thread means that the coiled wire is enclosed and incorporated into the chain stitch thread. As a result, the coiled electric wire follows the fabric well, does not have excessive slack, does not cause kinks, and becomes a conductive wiring that is easy to use.
　コイル状電線は前記チェーンステッチ糸の環１～２０個当たり１個の割合で連続的又は間欠的に環内に縫い留まっているのが好ましい。これにより、コイル状電線は生地との追従性を制御できる。 It is preferable that the coiled electric wire is sewn continuously or intermittently into the rings at a rate of one per 1 to 20 rings of the chain stitch thread. Thereby, the followability of the coiled wire with the fabric can be controlled.
　コイル状電線のコイルの内部にさらに芯糸を存在させてもよい。芯糸の太さは直径０．０１～２０ｍｍが好ましい。芯糸は伸縮性糸又は非伸縮性糸が好ましい。芯糸に伸縮性糸を使用した場合は、導電配線に伸縮性を付与できる。この伸縮性は、チェーンステッチ糸の引張限度の長さを上限とし、コイル状電線のコイルの圧縮限度の長さを下限とした範囲の制御された伸縮性である。コイル状電線のコイルの圧縮限度の長さを１００％としたとき、概ね、１０１～３００％の範囲で伸ばすことが可能である。芯糸に非伸縮性糸を使用した場合は、コイル状電線の寸法安定性を高めることができるほか、コイル状電線の補強効果を高めることができる。伸縮性糸の材料は、ゴム、ウレタン、シリコーン、熱可塑性エラストマー、合成繊維からなるコンジュゲートマルチフィラメント糸などが好ましい。芯糸の材料は後に説明するチェーンステッチ糸の材料と同様なものも使用できる。 A core thread may be further present inside the coil of the coiled electric wire. The thickness of the core yarn is preferably 0.01 to 20 mm in diameter. The core yarn is preferably a stretchable yarn or a non-stretchable yarn. When a stretchable thread is used as the core thread, stretchability can be imparted to the conductive wiring. This elasticity is a controlled elasticity within a range from an upper limit to the tensile limit length of the chain stitch thread to a lower limit to the compressive limit length of the coil of the coiled wire. When the length of the compression limit of the coil of the coiled electric wire is taken as 100%, it is generally possible to extend the length in the range of 101 to 300%. When a non-stretchable yarn is used as the core yarn, not only can the dimensional stability of the coiled electric wire be improved, but also the reinforcing effect of the coiled electric wire can be enhanced. Preferred materials for the stretchable thread include conjugate multifilament threads made of rubber, urethane, silicone, thermoplastic elastomer, and synthetic fibers. The material for the core thread may be the same as that for the chain stitch thread, which will be explained later.
　チェーンステッチ糸はシート（被縫製物）に連続して環縫いされていることが好ましい。シート（被縫製物）は、紙、樹脂シート、樹脂フィルム、織物、編み物、不織布などいかなるものであってもよい。ウエアラブル衣料の場合は、衣料又はその副資材（例えばベルト、補強布、保護布など）の生地にチェーンステッチ糸を縫製してもよい。あるいは、チェーンステッチ糸はシート（被縫製物）に沿ってシート（被縫製物）を破り、導電配線を取り出してもよい。 It is preferable that the chain stitch thread is chain-stitched continuously on the sheet (sewn object). The sheet (material to be sewn) may be of any material such as paper, resin sheet, resin film, woven fabric, knitted fabric, or nonwoven fabric. In the case of wearable clothing, chain stitch threads may be sewn onto the fabric of the clothing or its accessory materials (for example, belts, reinforcing fabrics, protective fabrics, etc.). Alternatively, the chain stitch thread may tear the sheet (sewn object) along the sheet (sewn object) to take out the conductive wiring.
　本発明の導電配線の製造方法は、ミシンにより、チェーンステッチ糸の環がシートの一面に連続して形成するように環縫いする。ミシンは、例えばタジマ工業社販売、環縫いハンドル刺繍機、商品名ＴＣＭＸシリーズがある。但し、チェーンステッチ糸の環に、コイル状電線を縫い留めて一体化すること、及びコイル状電線のコイルの内部にさらに芯糸を配置することは、本発明者の着想である。 In the method for manufacturing conductive wiring of the present invention, chain stitching is performed using a sewing machine so that a ring of chain stitch thread is continuously formed on one side of the sheet. Sewing machines include, for example, a chain-stitch handle embroidery machine sold by Tajima Kogyo Co., Ltd. under the trade name TCMX series. However, it was the inventor's idea to sew and integrate the coiled electric wire into the ring of the chain stitch thread, and to further arrange the core thread inside the coil of the coiled electric wire.
　チェーンステッチ糸としては、例えばコットン、麻、ウール、シルク等の天然繊維、ポリエステル、ナイロン、アクリル、ビニロン、ポリオレフィン、パラ系アラミド、メタ系アラミド、ポリアリレート、ポリベンズオキサゾール等の合成繊維、レーヨン等の再生繊維や、ゴム、ウレタン、シリコーン、熱可塑性エラストマーが好ましい。チェーンステッチ部分に導電性を付与する場合の線材や糸は、銅線、アルミニウム線、ステンレス線、タングステン(W)、モリブデン(Mo)、金属めっき繊維などいかなる導電素材であってもよい。チェーンステッチ糸は、フィラメント糸でもよいし紡績糸でもよい。一例として、ポリエチレンテレフタレートとポリテトラメチレンテレフタレート等の異種のポリエステルを複合紡糸したポリエステルコンジュゲートマルチフィラメント糸も使用できる。市販品として、東レ社製、商品名”Ｔ４００”がある。また、コイル状の芯へ、ゴム糸に組み物で被覆した手芸用の伸縮紐を使用したり、組み物や撚糸物などの加工物も使用できる。チェーンステッチ糸の好ましい直径は１０μｍ～３ｍｍである。
　前記チェーンステッチ糸は、融点２００℃以上の高融点合成繊維糸と、融点２００℃未満の低融点合成繊維糸を含み、前記融点合成繊維糸は融着されていることが好ましい。これにより、チェーンステッチ構造だけでは耐えられない引っ張りや擦れによるコイル状電線素材の位置ずれを、チェーンステッチ素材を溶解させて芯糸や生地と接着することで防止することができる。高融点合成繊維糸としては例えば融点が約２６０℃のポリエチレンテレフタレートマルチフィラメント糸があり、低融点合成繊維糸としては融点が約７０℃の共重合ナイロン糸がある。 Examples of chain stitch threads include natural fibers such as cotton, hemp, wool, and silk, synthetic fibers such as polyester, nylon, acrylic, vinylon, polyolefin, para-aramid, meta-aramid, polyarylate, and polybenzoxazole, and rayon. Preferred are recycled fibers, rubber, urethane, silicone, and thermoplastic elastomer. The wire or thread used to impart conductivity to the chain stitch portion may be any conductive material such as copper wire, aluminum wire, stainless steel wire, tungsten (W), molybdenum (Mo), or metal-plated fiber. The chain stitch thread may be filament thread or spun thread. As an example, a polyester conjugate multifilament yarn obtained by composite spinning of different types of polyesters such as polyethylene terephthalate and polytetramethylene terephthalate can also be used. A commercially available product is manufactured by Toray Industries, Inc. under the trade name "T400." Further, it is also possible to use an elastic cord for handicrafts made of rubber thread covered with braid, or to use processed materials such as braid or twisted yarn for the coiled core. The preferred diameter of the chain stitch thread is between 10 μm and 3 mm.
It is preferable that the chain stitch yarn includes a high melting point synthetic fiber yarn with a melting point of 200° C. or higher and a low melting point synthetic fiber yarn with a melting point of less than 200° C., and the melting point synthetic fiber yarn is fused. This makes it possible to prevent misalignment of the coiled wire material due to tension and friction, which cannot be withstood by the chain stitch structure alone, by melting the chain stitch material and adhering it to the core yarn or fabric. Examples of high melting point synthetic fiber yarns include polyethylene terephthalate multifilament yarns with a melting point of about 260°C, and low melting point synthetic fiber yarns include copolymerized nylon yarns with a melting point of about 70°C.
　コイル状電線の太さは、直径０．００５～１０ｍｍが好ましい。コイルの直径は０．０２～４０ｍｍが好ましい。コイル状電線は、銅線、アルミニウム線、ステンレス線、タングステン(W)、モリブデン(Mo)、金属めっき繊維などいかなるものであってもよい。電線は、裸糸電線又は被覆電線を使用できる。被覆電線の場合、被覆物は、ゴム、樹脂、補強繊維入りゴム、補強繊維入り樹脂などいかなるものであってもよい。コイル状電線材料は直線状が好ましい。直線状の電線は、チェーンステッチ糸の環内に縫い留めてチェーンステッチ糸を一体化すると、所定の距離（例えば２～２０ｍｍ）ごとにチェーンステッチ糸の環内に固定され、それ以外はフリーとなるので、コイル状になる。コイル状電線素材として、被覆電線を２本撚り合わせたツイストペアケーブルを使用することが好ましい。この理由は、電気信号伝達の為の電線が平行である場合、飛来ノイズの電磁波によって磁場が発生すると、それに伴う起電力が発生し、誘導電流が発生しノイズ源となる。この対策として、２本以上電線をねじり合わせることで、ねじれ毎に起電力が逆向きに働き、起電力がノイズを打ち消しあうようになり、飛来ノイズからの影響を低減できる。このツイスト電線をコイル電線素材に使用することで、追従性が良く、且つノイズを低減したコイル状電線ができる。
　またフレキシブルプリント回路基板やフレキシブルプリント配線板(ＦＰＣ)と呼ばれるポリイミド等の絶縁性を持った薄く柔らかいベースフィルムと銅箔等の導電性金属を貼り合わせた基材に１本～複数線の電気回路を形成した基板を、細幅形状に加工した長尺ＦＰＣと呼ばれるものや、樹脂シートや樹脂フィルムなどに導電性インクをプリントした配線を細幅形状に加工したもの、導電性の箔や不織布、紙、樹脂シート、樹脂フィルムなどを細幅形状にスリットしたテープを導電線として使用できる。これら細幅形状の導電線の幅は０．０５～１５ｍｍ、厚み０．０１～３ｍｍが好ましい。 The thickness of the coiled electric wire is preferably 0.005 to 10 mm in diameter. The diameter of the coil is preferably 0.02 to 40 mm. The coiled electric wire may be made of any material such as copper wire, aluminum wire, stainless steel wire, tungsten (W), molybdenum (Mo), or metal-plated fiber. As the electric wire, a bare thread electric wire or a covered electric wire can be used. In the case of a covered electric wire, the covering may be made of any material such as rubber, resin, rubber containing reinforcing fibers, or resin containing reinforcing fibers. The coiled wire material preferably has a straight shape. When a straight electric wire is sewn into a ring of chain stitch thread to integrate the chain stitch thread, it is fixed within the ring of chain stitch thread at predetermined distances (for example, 2 to 20 mm), and the rest is free. As a result, it becomes coiled. As the coiled wire material, it is preferable to use a twisted pair cable in which two coated wires are twisted together. The reason for this is that when electric wires for transmitting electric signals are parallel, when a magnetic field is generated by electromagnetic waves of flying noise, an accompanying electromotive force is generated, and an induced current is generated, which becomes a noise source. As a countermeasure for this, by twisting two or more wires together, the electromotive force acts in the opposite direction for each twist, and the electromotive force cancels out the noise, reducing the influence of flying noise. By using this twisted wire as a coiled wire material, a coiled wire with good followability and reduced noise can be obtained.
In addition, electrical circuits with one to multiple wires are mounted on a base material called a flexible printed circuit board or flexible printed wiring board (FPC), which is made by laminating a thin, soft base film with insulating properties such as polyimide and a conductive metal such as copper foil. There are long FPCs, which are made by processing a board on which a board has been formed into a narrow shape, wires printed with conductive ink on a resin sheet or film, which are processed into a narrow shape, conductive foils, non-woven fabrics, etc. A tape made by slitting paper, resin sheet, resin film, etc. into narrow shapes can be used as the conductive wire. The width of these narrow conductive wires is preferably 0.05 to 15 mm, and the thickness is preferably 0.01 to 3 mm.
　本発明は、被覆絶縁されていない金属ワイヤーや金属メッキ繊維、細幅形状の導電性テープ等の裸導電線を、コイル状部分に用いることで、脈拍や筋電位を測定するウエアラブル衣料や、電気刺激治療器具において肌へ接する電極として使用可能である。またコイル状部分は１本もしくは複数本同時に引きそろえて巻き付けることが出来、この裸導電線同士が接するように巻き付けた場合や、生地に縫い留めた場合、電路が増えて電流がより流れやすくなる。さらにコイル状部分に加えチェーンステッチ部分も同様に被覆絶縁されていない金属ワイヤーや金属メッキ繊維等を用いた場合も、裸導電線同士が接するので電路が増えて電流が流れやすくなる。生地に縫い留めた場合は表面にコイル状部分、裏面にチェーンステッチが配置されるので、表面から裏面への電路も確保できる。この導電配線は生地に縫い付けたまま使用してもよいし、生地を破る、溶解させるなどして分離し使用してもよい。例えば、コイル状部分に撚糸物を使用する、あるいはコイル状部分とチェーンステッチ部分へ、導電性の金属線や繊維と水溶性ビニロンの撚糸物を使用し、配線製造後に水溶性ビニロンを溶解除去して導電素材を露出させ、導電素材同士の接点を増やし電路を多くすることができる。 The present invention uses bare conductive wires such as uninsulated metal wires, metal-plated fibers, and narrow conductive tapes in coiled parts to produce wearable clothing that measures pulse and myoelectric potential, and electrical It can be used as an electrode in contact with the skin in a stimulation therapy device. In addition, the coiled part can be wrapped in single or multiple wires at the same time, and if these bare conductive wires are wrapped so that they touch each other, or if they are sewn into fabric, the number of electrical paths will increase and the current will flow more easily. . Furthermore, if uninsulated metal wire or metal-plated fiber is used for the chain stitch portion in addition to the coiled portion, the bare conductive wires will come into contact with each other, increasing the number of electrical paths and making it easier for current to flow. When sewn into fabric, there will be a coiled part on the front side and a chain stitch on the back side, so it will also ensure an electrical path from the front side to the back side. This conductive wiring may be used as it is sewn into the fabric, or it may be separated and used by tearing or dissolving the fabric. For example, use a twisted yarn for the coiled part, or use a twisted yarn of conductive metal wire or fiber and water-soluble vinylon for the coiled part and the chain stitch part, and dissolve and remove the water-soluble vinylon after the wiring is manufactured. By exposing the conductive material, it is possible to increase the number of points of contact between the conductive materials and increase the number of electrical paths.
　以下、図面を用いて説明する。以下の図面において、同一符号は同一物を示す。図１は本発明の一実施形態で使用する、シートに環縫いしたチェーンステッチ糸４の模式的工程説明図である。１はチェーンステッチ糸４を形成するためのチェーンステッチ製造装置である。送り方向Ｐに対して鉤針２及びルーパ５の向きを１８０度反転させた場合を示している。すなわち、説明のため上下を逆転させている。この場合、鉤針２が最上点に達して、下向きの移動に切り替わっても、鉤針２の鉤部２ａの向きとシート（被縫製物）Ａの送り方向Ｐと逆になっているため、供給糸Ｂは鉤針２の鉤部２ａに係合されたまま、鉤針２とともに移動し、環３は送り方向Ｐと反対方向に押し倒される。
　そして、鉤針２がシート（被縫製物）Ａを下向きに貫通する際に、鉤針２の鉤部２ａから外れる。この時、鉤針２は供給糸Ｂの環３の内部３ａに位置しているので、次の供給糸Ｂが環状に引き上げられて形成される環３は、前の環３の内部３ａから引き上げられる。これを繰り返すことによって、シート（被縫製物）Ａの上面Ａ１には、連続する環３が鎖状に連結されて、チェーンステッチ糸４が形成される。シート（被縫製物）Ａは、環３と裏側の糸３ｂとの間に位置し、縫製穴６が形成される。シート（被縫製物）Ａが紙の場合は、この縫製穴６に沿って破ることが容易であり、シート（被縫製物）Ａを除去できる。このようにして、環縫いされたチェーンステッチ糸４単体を取り出しできる。次に説明するコイル状電線をチェーンステッチ糸の環内に縫い留めてチェーンステッチ糸を一体化した場合、あるいはコイル状電線のコイルの内部にさらに芯糸を存在させた場合も、同様にしてシート（被縫製物）Ａを除去できる。
　　図２は本発明の一実施形態で使用する、シートに環縫いしたチェーンステッチ糸４の模式的説明図である。 This will be explained below using the drawings. In the following drawings, the same reference numerals indicate the same parts. FIG. 1 is a schematic process explanatory diagram of a chain stitch thread 4 used in an embodiment of the present invention to chain stitch a sheet. 1 is a chain stitch manufacturing device for forming chain stitch thread 4; A case is shown in which the orientations of the hook needle 2 and the looper 5 are reversed by 180 degrees with respect to the feeding direction P. In other words, it has been turned upside down for explanation purposes. In this case, even if the hook 2 reaches the highest point and switches to downward movement, the direction of the hook 2a of the hook 2 is opposite to the feed direction P of the sheet (workpiece) A, so the supply thread B moves together with the hook 2 while being engaged with the hook 2a of the hook 2, and the ring 3 is pushed down in a direction opposite to the feeding direction P.
Then, when the hook needle 2 passes downward through the sheet (material to be sewn) A, it comes off from the hook portion 2a of the hook needle 2. At this time, the hook 2 is located inside 3a of the ring 3 of the supply yarn B, so the ring 3 formed by pulling up the next supply yarn B in an annular shape is pulled up from the inside 3a of the previous ring 3. . By repeating this, continuous rings 3 are connected in a chain shape on the upper surface A1 of the sheet (workpiece) A, and a chain stitch thread 4 is formed. The sheet (material to be sewn) A is located between the ring 3 and the thread 3b on the back side, and has a sewing hole 6 formed therein. If the sheet (material to be sewn) A is paper, it can be easily torn along the sewing holes 6, and the sheet (material to be sewn) A can be removed. In this way, the single chain stitch thread 4 that has been chain stitched can be taken out. In the case where the chain stitch thread is integrated by sewing the coiled electric wire described below inside the ring of chain stitch thread, or when the core thread is further present inside the coil of the coiled electric wire, the same process can be applied to the sheet. (Object to be sewn) A can be removed.
FIG. 2 is a schematic explanatory diagram of a chain stitch thread 4 used in an embodiment of the present invention and chain-stitched on a sheet.
　図３は本発明の一実施形態のコイル状電線７をチェーンステッチ糸の環内に縫い留めてチェーンステッチ糸４を一体化した模式的説明図である。 FIG. 3 is a schematic explanatory diagram of an embodiment of the present invention in which the coiled electric wire 7 is sewn into the ring of the chain stitch thread to integrate the chain stitch thread 4.
　図４は本発明の一実施形態のコイル状電線７のコイルの内部にさらに芯糸８を存在させ、チェーンステッチ糸４を一体化した模式的説明図である。 FIG. 4 is a schematic explanatory diagram in which a core thread 8 is further present inside the coil of a coiled electric wire 7 according to an embodiment of the present invention, and a chain stitch thread 4 is integrated.
　図５はチェーンステッチ糸を環縫いする際に環内にコイル状電線を縫い留めている側面写真である。図５の写真中、右端は被覆電線を供給する治具である。図６は図５の拡大側面写真、図７は図６の状態からミシン目に沿って台紙の下部を除去した側面写真、図８は図７の状態からミシン目に沿って台紙を全部除去した側面写真である。このようにして、被覆電線とチェーンステッチ糸が一体化した配線を作成する。 Figure 5 is a side view photograph of the coiled wire being sewn into the ring when chain stitching the chain stitch thread. In the photograph of FIG. 5, the right end is a jig for supplying the covered electric wire. Figure 6 is an enlarged side view of Figure 5, Figure 7 is a side view of the state shown in Figure 6 with the lower part of the mount removed along the perforations, and Figure 8 is the state of Figure 7 in which the entire mount has been removed along the perforations. This is a side photo. In this way, wiring in which the covered wire and chain stitch thread are integrated is created.

　得られた導電配線は、ウエアラブル衣料に好適であった。 (Example 1)
(1) Chain Stitch Thread One polyester conjugate multifilament thread (manufactured by Toray Industries, Inc., trade name "T400") with a total fineness of 330 decitex and 68 filaments (diameter approximately 0.3 mm) was used as the chain stitch thread.

The obtained conductive wiring was suitable for wearable clothing.

（３）芯素材
　芯素材として、シリコンチューブ（内径０．５ｍｍ、外径１ｍｍ）を使用した。
（４）導電配線の作成
　縫い付け生地として、ポリエステルフェルト生地を使用した。この導電配線は、生地に縫い付けたまま使用してもよいし、生地を破る、溶解させるなどして分離し使用してもよい。
　図１３は生地に縫い留められたコイル状部分（生地オモテ面）の状態の平面写真であり、図１４は生地に縫い留められたチェーンステッチ状部分（生地ウラ面）の状態の平面写真であり、図１５は生地より配線を分離した状態の側面写真であり、表裏が無くなりコイル状部分とチェーンステッチ部分が交差している様子が芯の表面に観察できる。
　得られた導電配線は、ウエアラブル衣料に好適であった。
　本実施例の導電配線は、被覆絶縁されていない金属ワイヤー裸導電線を、コイル状部分に用いることで、脈拍や筋電位を測定するウエアラブル衣料や、電気刺激治療器具において肌へ接する電極として使用可能である。またコイル状部分は１本もしくは複数本同時に引きそろえて巻き付けることができ、この裸導電線同士が接するように巻き付けた場合や、生地に縫い留めた場合、電路が増えて電流がより流れやすくなる。さらにコイル状部分に加えチェーンステッチ部分も同様に被覆絶縁されていない金属ワイヤー裸線を用いているので、裸導電線同士が接触し、電路が増えて電流が流れやすくなる。生地に縫い留めた場合は表面にコイル状部分、裏面にチェーンステッチが配置されるので、表面から裏面への電路も確保できる。この導電配線は生地に縫い付けたまま使用してもよいし、生地を破る、溶解させるなどして分離し使用してもよい。 (Example 2)

(3) Core material A silicone tube (inner diameter 0.5 mm, outer diameter 1 mm) was used as the core material.
(4) Creation of conductive wiring Polyester felt fabric was used as the sewing fabric. This conductive wiring may be used while being sewn onto the fabric, or may be separated and used by tearing or dissolving the fabric.
Figure 13 is a plan view of the coiled part (front side of the fabric) sewn into the fabric, and Figure 14 is a plan view of the chain stitched part (back side of the fabric) sewn into the fabric. , FIG. 15 is a side view photograph of the wiring separated from the fabric, and it can be seen on the surface of the core that the front and back sides are gone and the coiled part and chain stitch part intersect.
The obtained conductive wiring was suitable for wearable clothing.
The conductive wiring of this example uses a bare conductive wire of uninsulated metal wire in the coiled part, and can be used as an electrode that comes into contact with the skin in wearable clothing that measures pulse and myoelectric potential, and electrical stimulation treatment equipment. It is possible. In addition, the coiled part can be wrapped in one or more lines at the same time, and if these bare conductive wires are wrapped so that they touch each other, or if they are sewn into fabric, the number of electrical paths increases and current flows more easily. . Furthermore, in addition to the coiled part, the chain stitch part also uses bare metal wires that are not coated and insulated, so the bare conductive wires come into contact with each other, increasing the number of electrical paths and making it easier for current to flow. When sewn into fabric, there will be a coiled part on the front side and a chain stitch on the back side, so it will also ensure an electrical path from the front side to the back side. This conductive wiring may be used as it is sewn into the fabric, or it may be separated and used by tearing or dissolving the fabric.
