Description
本発明は衣類としての機能とディバイスの電源供給路、通信路としての導電性を兼ね備えた素材に関する。 The present invention relates to a material having both a function as clothing, a power supply path for a device, and conductivity as a communication path.
近年、ウエアラブルコンピューター、ユビキタスコンピューティング、メディアファッションといった言葉が注目を浴びている。これらはコンピュータ、各種センサー、アクチュエーター、ディスプレー等を衣服や装身品に装着することにより成り立つ。 In recent years, words such as wearable computers, ubiquitous computing, and media fashion have attracted attention. These are established by attaching a computer, various sensors, actuators, displays, etc. to clothes and accessories.
従来の技術ではコンピュータ、各種センサー、アクチュエーター、ディスプレー等を衣服に装着しそれらの有機的な結合を実現するため電源とデータ通信路の確保の為に多くのケーブルを用いていた。 In the prior art, a computer, various sensors, actuators, displays, etc. are attached to clothes and many cables are used to secure a power source and a data communication path in order to realize an organic coupling between them.
従来技術では、電源及びデータ通信路を確保するにあたり、各々のディバイスに対し独立したケーブルを連結することになる。ケーブルを衣服、装身品に装着した場合、重い、動きの邪魔になる、外観的にもファッショナブルとは言い難い等々、衣服、装身品としての機能が大幅に損なわれてしまい、日常生活で使用可能なものではなかった。またディバイス毎に単独電源と通信経路を持たねばならず、システムとしての拡張性にも乏しくコスト面でも問題があった。本発明は衣服、装身品として必要な機能である柔軟性、軽さ、色、素材感、手触り等のファッション性を具備した上で電源、通信路用ケーブルとしての機能を持つ平面電極及びそれを構成するのに最適な導電性布帛を提供することにある。 In the prior art, in order to secure a power source and a data communication path, an independent cable is connected to each device. When a cable is attached to clothing or accessories, the function as clothing or accessories is greatly impaired, such as being heavy, obstructing movement, and not being fashionable in appearance. It was not usable in. In addition, each device must have a single power supply and a communication path, and the system is not very scalable and has a problem in terms of cost. The present invention provides a flat electrode having a function as a cable for a power source and a communication path, as well as having fashionability such as flexibility, lightness, color, texture, and touch as functions necessary for clothes and accessories. It is an object of the present invention to provide an electrically conductive fabric that is optimal for constituting the above.
本発明者らは、上記課題を解決するために鋭意研究の結果、本発明をするに至った。つまり、本発明は第一に、繊維にめっきしてなる導電糸と非導電糸からなる布帛で、布帛の一方の表面はその面積の７０％以上を導電糸が占め、もう一方の表面はその面積の７０％以上を非導電糸が占めることを特徴とする導電性布帛である。ここで、繊維にめっきしてなる導電糸と非導電糸からなる布帛は、編物であることが好ましい。 The inventors of the present invention have made the present invention as a result of intensive studies in order to solve the above problems. That is, the present invention is primarily a fabric made of conductive yarn and non-conductive yarn plated on a fiber, and one surface of the fabric occupies 70% or more of the area, and the other surface is the A conductive fabric characterized in that non-conductive yarn occupies 70% or more of the area. Here, the fabric made of conductive yarn and non-conductive yarn plated on the fiber is preferably a knitted fabric.
また、本発明は第二に、上記導電性布帛に電気絶縁層を貼り合わせてなる絶縁層付き導電性布帛である。絶縁層としては繊維布帛、高分子フィルム、エラストマーシートから選ばれる一種以上である事が好ましい。加えて、これら絶縁層が透湿防水性を有する事が好ましい。 A second aspect of the present invention is a conductive fabric with an insulating layer formed by bonding an electrical insulating layer to the conductive fabric. The insulating layer is preferably at least one selected from a fiber fabric, a polymer film, and an elastomer sheet. In addition, it is preferable that these insulating layers have moisture permeability and waterproofness.
更に、本発明は第三に、第一の発明である導電性布帛二枚の間に絶縁層を挟み形成された平面電極である。絶縁層としては繊維布帛、高分子フィルム、エラストマーシートから選ばれる一種以上である事が好ましい。また、第二の発明である絶縁層付き導電性布帛を二枚重ねて形成された平面電極である。或いは第一の発明の導電性布帛と第二の発明である絶縁層付き導電性布帛により形成された平面電極である。 Furthermore, the present invention thirdly relates to a planar electrode in which an insulating layer is sandwiched between two conductive fabrics according to the first invention. The insulating layer is preferably at least one selected from a fiber fabric, a polymer film, and an elastomer sheet. Moreover, it is a planar electrode formed by overlapping two conductive fabrics with an insulating layer according to the second invention. Or it is the plane electrode formed with the conductive fabric of 1st invention, and the conductive fabric with an insulating layer which is 2nd invention.
本発明によれば、導電糸が主となる面は電極としての導電性を確保し、非導電糸が主となる面は通常の繊維布帛に用いる方法で容易に着色が可能で、手触り、柔軟性等を含めファッション性の面で通常の布帛として用いて何ら違和感のない導電性布帛を得る事が出来る。また、この導電性布帛を二枚用い、非導電糸が主となる面を外側として構成することで、ファッション性に優れた平面電極を得る事が出来る。 According to the present invention, the surface mainly composed of the conductive yarn ensures the conductivity as an electrode, and the surface mainly composed of the non-conductive yarn can be easily colored by a method used for a normal fiber fabric, and is soft and flexible. It is possible to obtain a conductive fabric having no sense of incongruity by using it as a normal fabric in terms of fashion, including properties. Moreover, the plane electrode excellent in fashionability can be obtained by using 2 sheets of this conductive fabric and making the surface where non-conductive yarn is mainly used as the outside.
導電糸としては繊維にめっきしてなる導電糸であって、所定の導電性を有していれば、繊維素材、めっきの金属種は特に限定されない。使用時の耐久性、製編・染色時に於ける性能劣化、コスト等を考えると、合成繊維に銀めっきを施した糸が最も好ましい。 The conductive yarn is a conductive yarn formed by plating a fiber, and the fiber material and the metal type of plating are not particularly limited as long as the conductive yarn has predetermined conductivity. In view of durability during use, performance deterioration during knitting and dyeing, cost, and the like, a thread obtained by silver-plating synthetic fibers is most preferable.
一方、非導電糸については特に制限はない。導電布の使われ方、用途等にあわせ必要機能、外観、風合い、触感等を考慮して選択すればよい。 On the other hand, there is no particular limitation on the non-conductive yarn. It may be selected in consideration of necessary functions, appearance, texture, touch, etc. according to the usage and application of the conductive cloth.
布帛の全て又は一部に前記導電糸を用いて構成することにより導電性布帛ができる。当目的に使用する導電性布帛は平面電極として用いる為、全方向に導電性を有する必要がある。布帛が編物の場合には、糸をループ状に絡ませることで平面が形成される為、電圧をかけた場合の面方向の導電性は、絡んだ糸間の電流の流れ易さに支配されることになる。つまり交絡した糸間の電気抵抗を小さくすることで導電性を高くすることが出来る。導電糸１００％で布帛を構成する場合は問題ないが、導電糸と非導電糸とで布帛を構成する場合には、糸や組織で工夫する事で必要な導電性を有する布帛を得る事が出来る。 A conductive fabric can be formed by using the conductive yarn for all or part of the fabric. Since the conductive fabric used for this purpose is used as a planar electrode, it is necessary to have conductivity in all directions. When the fabric is a knitted fabric, a plane is formed by entwining the yarn in a loop shape. Therefore, the electrical conductivity in the surface direction when a voltage is applied is governed by the ease of current flow between the entangled yarns. Will be. That is, the electrical conductivity can be increased by reducing the electrical resistance between the entangled yarns. There is no problem when the fabric is composed of 100% conductive yarn, but when the fabric is composed of conductive yarn and non-conductive yarn, it is possible to obtain a fabric having the necessary conductivity by devising with the yarn or the structure. I can do it.
導電糸と非導電糸を混合して布帛にする方法として（1）導電糸と非導電糸を混合した糸を用いて布帛とする（２）導電糸を布帛全体に均一存在するようにする（３）導電糸を布帛の平面の中で偏在させる（４）導電糸を布帛の片面に偏在させる、等の方法が考えられるが（１）、（２）、（３）の方法は基盤としての全方位の導電性を持つこと及び布帛の構造上糸間での電気抵抗を極力小さくする必要がある点で不適であり、（４）の方法が最適である。 As a method of mixing a conductive yarn and a non-conductive yarn into a fabric, (1) a fabric using a mixture of a conductive yarn and a non-conductive yarn is used. (2) The conductive yarn is uniformly present throughout the fabric ( 3) The method of (1), (2), (3) as a base is conceivable, for example, the method in which the conductive yarn is unevenly distributed in the plane of the fabric, (4) the conductive yarn is unevenly distributed on one side of the fabric, etc. The method (4) is optimal because it has omnidirectional conductivity and it is necessary to minimize the electrical resistance between yarns due to the structure of the fabric.
布帛の片面に導電糸を偏在させる方法としては、公知公用の手法を用いる事が出来るが、いわゆる二重組織の織編物とすることが好ましい。導電糸が偏在する面では全方位の導電性を持たせ、非導電糸が偏在する面は外観や意匠性、触感などに優れたものとするために、一方の面では導電糸が表面積の７０％以上を占め、他方の面では非導電糸が表面積の７０％以上を占める事が必要である。一方の面において導電糸の占める面積が７０％未満では、全方位において十分な導電性を得る事が出来ない虞があり、他方の面において非導電糸の占める面積が７０％未満では、着色性、肌触り、柔軟性が不足する虞がある。 As a method of unevenly distributing the conductive yarn on one side of the fabric, a publicly known method can be used, but a so-called double-textured knitted fabric is preferable. In order to provide conductivity in all directions on the surface where the conductive yarn is unevenly distributed and to make the surface where the nonconductive yarn is unevenly excellent in appearance, design, touch, etc., the conductive yarn on one surface has a surface area of 70. It is necessary that the non-conductive yarn occupies 70% or more of the surface area on the other side. If the area occupied by the conductive yarn on one side is less than 70%, sufficient conductivity may not be obtained in all directions, and if the area occupied by the non-conductive yarn on the other side is less than 70%, the coloring property may not be obtained. , There is a risk of lack of touch and flexibility.
このようにして得られる導電性布帛を用いて平面電極とする場合、二枚の導電性布帛と絶縁層を接着剤又は縫製により積層して使われることとなる。通常、布帛とフィルム、布帛同士を貼り合わせると柔軟性が損なわれるため、本発明の導電性布帛としては貼り合わせても比較的柔軟である編物が好ましい。 In the case of using the conductive cloth thus obtained as a planar electrode, two conductive cloths and an insulating layer are laminated by an adhesive or sewing. Usually, when a fabric and a film and fabrics are bonded together, the flexibility is impaired. Therefore, the conductive fabric of the present invention is preferably a knitted fabric that is relatively flexible even when bonded.
編物としては、丸編み、トリコット、ラッセル、緯編みのいずれも使用することができる。これらの布帛において、一方の表面に導電糸がより多く露出し、他方の表面には非導電糸がより多く露出する様な編み組織、糸使いの編構造にする事で目的を達成できる。糸使い、編み組織等は用途、伸び・厚み・意匠性等の要求に合わせ適宜選択できる。 As the knitted fabric, any of circular knitting, tricot, russell and weft knitting can be used. In these fabrics, the object can be achieved by forming a knitting structure or a knitting structure using yarns such that more conductive yarn is exposed on one surface and more non-conductive yarn is exposed on the other surface. Yarn use, knitting structure and the like can be appropriately selected according to the requirements of use, elongation / thickness, and design.
非導電糸と導電糸が布帛の別々の表面に偏在する編み組織にすることで、摩耗、摩擦、汗等による導電性劣化を防ぐことも可能となる。つまり導電糸が表面に露出しないことで、着用、使用時に導電糸が摩擦、摩耗、汗によるストレスを受け難くなる。 By using a knitted structure in which the non-conductive yarn and the conductive yarn are unevenly distributed on different surfaces of the fabric, it is possible to prevent deterioration of conductivity due to wear, friction, sweat, and the like. That is, since the conductive yarn is not exposed on the surface, the conductive yarn is hardly subjected to stress due to friction, wear, and sweat during wearing and use.
この導電性布帛を用いて平面電極を形成する場合、二枚の導電性布帛の間に絶縁層を積層する必要がある。つまりこの絶縁層と電極たる二枚の導電性布帛を貼り合わせるか縫製の際に縫い合わせる形で積層し使用されることになる。 When a planar electrode is formed using this conductive fabric, it is necessary to laminate an insulating layer between the two conductive fabrics. That is, the insulating layer and two conductive cloths as electrodes are laminated or used in a form of stitching together at the time of sewing.
絶縁層の目的は、両極となる二枚の導電性布帛同士の接触による短絡を防止することである。この目的で繊維布帛、フィルム、エラストマーシート等を用いることができる。通常の着用環境、使用環境に於いては、繊維布帛、好ましくは伸縮性に富む繊維布帛、特に好ましくは編物を用いることで、柔軟性、通気性を阻害せずに目的を達することができる。繊維布帛の厚み、糸密度を増せば絶縁性の信頼性も上がるが、重くなり、最終的な平面電極が厚くなる為、目的に合わせて適宜決定する。発泡樹脂フィルムもこの目的に使用することができる。ウレタンフォームは柔軟性を重要視する場合有効な絶縁層となり得る。 The purpose of the insulating layer is to prevent a short circuit due to contact between the two conductive fabrics serving as both electrodes. For this purpose, fiber fabrics, films, elastomer sheets and the like can be used. In a normal wearing environment and use environment, the object can be achieved without impairing flexibility and breathability by using a fiber fabric, preferably a fiber fabric rich in stretchability, particularly preferably a knitted fabric. Increasing the thickness and yarn density of the fiber fabric increases the reliability of insulation, but it becomes heavier and the final planar electrode becomes thicker. Foamed resin films can also be used for this purpose. Urethane foam can be an effective insulating layer when flexibility is important.
しかし繊維布帛を絶縁層として用いた場合、水に濡れると絶縁性が破壊され、２極が短絡してしまう虞がある。この点を解決するためには絶縁層に防水機能を付与すればよい。絶縁層として繊維布帛を選択した場合、布帛に撥水加工、防水コーティング、防水ラミネート等の処理をする事で防水性を付与できる。ここでの撥水加工、防水コーティング、防水ラミネートは公知の方法を用いる事ができ、撥水加工はフッ素系の撥水剤を繊維に付与し熱処理する方法が、またコーティング、ラミネートはウレタンエラストマーを用いる方法がその性能、柔軟性が優れていることで特に好ましい。 However, when the fiber fabric is used as an insulating layer, the insulation property is destroyed when wetted with water, and the two electrodes may be short-circuited. In order to solve this problem, a waterproof function may be given to the insulating layer. When a fiber fabric is selected as the insulating layer, waterproofing can be imparted by treating the fabric with a water repellent treatment, a waterproof coating, a waterproof laminate, or the like. The water repellent finish, waterproof coating and waterproof laminate can use known methods. The water repellent finish is a method in which a fluorine-based water repellent is applied to the fiber and heat treated, and the coating and laminate are made of urethane elastomer. The method used is particularly preferred because of its excellent performance and flexibility.
絶縁層に高分子フィルムを使う場合も湿潤時の短絡を防止することができる。防水フィルムを絶縁層として用い、衣服として着用した場合、着用環境や着用時の運動の状況によってはムレが起こり、場合によっては衣服に結露する等して強い不快感を感じる虞がある。 Even when a polymer film is used for the insulating layer, a short circuit when wet can be prevented. When a waterproof film is used as an insulating layer and worn as a garment, stuffiness may occur depending on the wearing environment and the state of exercise during wearing, and in some cases, there is a risk of feeling strong discomfort due to condensation on the garment.
絶縁層として透湿防水性フィルムを採用すればこのムレ、不快感を解消できる。透湿防水フィルムとしては、無孔質タイプと有孔質タイプのいずれのタイプも使用可能である。無孔質タイプとしては、ウレタンエラストマーフィルム、エステルエラストマーフィルムがよく知られているが、透湿防水性があればこれらのフィルムに限らず使用可能である。有孔質フィルムとしては、フッ素系フィルム、ウレタン系フィルム、ポリエチレン系フィルム、ポリプロピレンフィルム等透湿防水性能があれば全て使用可能である。絶縁層としての透湿防水性フィルムは用途、使われ方等を考慮し決定される。 If a moisture-permeable and waterproof film is used as the insulating layer, this stuffiness and discomfort can be eliminated. As the moisture permeable waterproof film, either a nonporous type or a porous type can be used. As the nonporous type, a urethane elastomer film and an ester elastomer film are well known, but any film can be used as long as it has moisture permeability and waterproofness. As the porous film, any film can be used as long as it has moisture permeability and waterproof performance such as a fluorine film, a urethane film, a polyethylene film, and a polypropylene film. The moisture-permeable and waterproof film as the insulating layer is determined in consideration of the usage and usage.
