Description

導電性生地及びその製造方法Conductive fabric and method for producing the same
　本発明は、導電性生地及びその製造方法に関する。 The present invention relates to a conductive fabric and a method for producing the same.
　従来から、心電図や筋電図等のデータ採取、或いは電気治療や電磁波治療などを対象者に対して行う場合に使用する電極付き着衣が知られている(例えば、特許文献1参照)。このような着衣は、布生地に導電性糸を編み込むことにより電極を形成し、当該電極を介して心電信号や筋電信号を外部装置が検出できるように、或いは、電極を介して電流等を対象者に付与できるように構成されている。 2. Description of the Related Art Conventionally, electrode-equipped clothing that is used when collecting data such as electrocardiograms and electromyograms, or performing electrical therapy or electromagnetic wave therapy on a subject is known (for example, see Patent Document 1). In such clothes, an electrode is formed by weaving conductive yarn into a cloth, so that an external device can detect an electrocardiogram signal or myoelectric signal via the electrode, or an electric current or the like via the electrode. Can be given to the target person.
　また、布生地から構成される湿度感知生地も知られている(例えば、特許文献２参照)。湿度感知生地は、導電性に乏しい糸が導電性の糸の間に置かれるようにして、導電性の糸と導電性に乏しい糸とが編製されて構成されている。このような湿度感知生地は、湿度が変化すると電気抵抗が変化するため、導電性の糸の間の電気伝導度を外部装置を介して監視すれば、生地内に湿気が発生したことを検知できるというものであり、例えば、病院や介護施設におけるベッドマットやベッドシーツに適用され、入院等する患者の発汗状況等の確認に用いられている。 Also known is a humidity sensing fabric made of cloth fabric (see, for example, Patent Document 2). The humidity sensing fabric is formed by knitting a conductive yarn and a poorly conductive yarn so that the poorly conductive yarn is placed between the conductive yarns. Such a humidity sensing fabric changes its electrical resistance when the humidity changes. Therefore, if the electrical conductivity between the conductive yarns is monitored via an external device, it can be detected that moisture has occurred in the fabric. For example, it is applied to bed mats and bed sheets in hospitals and care facilities, and is used to check the sweating status of patients who are hospitalized.
　また、布生地に導電性糸を編み込むことにより導電部を形成し、当該導電部に外部装置である電源を接続して電圧を印加することにより導電部が発熱できるように構成された布ヒータも知られている(例えば、特許文献３参照)。 Also, there is a cloth heater configured to form a conductive portion by weaving conductive yarn into a cloth fabric, and connect the power source as an external device to the conductive portion and apply a voltage to the conductive portion to generate heat. It is known (see, for example, Patent Document 3).

The connection structure between them is not greatly devised, and the structure in which the conductive part and the connection terminal in the external device are simply connected via a conductive adhesive, or the connection terminal in the external device is configured in a clip shape. The actual situation is that only a conventional connection structure such as a structure in which a conductive portion is connected to the conductive fabric is used. In such a connection structure, the conductive fabric is continuously used or washed. There has been a problem that the conductor portion at the connection point tends to deteriorate.

　上記のような樹脂接着剤を導電性生地１０の所定個所（接続部１４に対応する箇所）に含浸させる方法は、種々の方法を採用することができる。例えば、上記の樹脂接着剤組成物をシート化したものを、導電性生地１０における接続部１４に対応する領域に載置すると共に、当該シート化された樹脂接着剤上に、外部装置における接続端子Ｚ（導電性の被着体）を載置し、当該接続端子Ｚ（被着体Ｚ）の上からヒートプレスすることにより行うことができる。なお、シート化した樹脂接着剤は、フィルム状に構成してもよいが、不織布状に構成する方が導電性生地１０の接続部１４における伸縮性を維持するという観点から好ましい。 Various methods can be adopted as a method of impregnating a predetermined portion (a portion corresponding to the connecting portion 14) of the conductive fabric 10 with the resin adhesive as described above. For example, the resin adhesive composition formed into a sheet is placed in a region corresponding to the connection portion 14 in the conductive fabric 10, and the connection terminal in the external device is placed on the sheeted resin adhesive. Z (conductive adherend) can be placed and heat-pressed from above the connection terminal Z (adherence Z). In addition, although the resin adhesive formed into a sheet may be configured in a film shape, it is preferable to configure it in a non-woven fabric shape from the viewpoint of maintaining stretchability at the connection portion 14 of the conductive fabric 10.
　ヒートプレスを行うことにより、導電性生地１０と被着体Ｚとの間に介在されるシート状の樹脂接着剤は、溶解して導電性生地１０の内部側に流動していき導電性生地１０に含浸されると共に、導電部１２及び非導電部１３における編地構造内に含浸された樹脂接着剤１５の接着作用により導電性生地１０と被着体Ｚとは接続固定されることとなる。ここで、導電性生地１０に含浸される樹脂接着剤は、導電部１２及び非導電部１３における編地構造内の他、地糸１３１と地糸１３１の間、地糸１３１と導電性糸１２１との間、導電性糸１２１と導電性糸１２１との間、地糸１３１及び導電性糸１２１をマルチフィラメント等の単繊維の集合体として構成した場合には、各短繊維の間等に存在することとなる。 By performing the heat press, the sheet-like resin adhesive interposed between the conductive fabric 10 and the adherend Z dissolves and flows toward the inside of the conductive fabric 10. The conductive fabric 10 and the adherend Z are connected and fixed by the adhesive action of the resin adhesive 15 impregnated in the knitted fabric structure in the conductive portion 12 and the nonconductive portion 13. Here, the resin adhesive impregnated in the conductive fabric 10 is not only in the knitted fabric structure in the conductive portion 12 and the non-conductive portion 13, but also between the ground yarn 131 and the ground yarn 131, between the ground yarn 131 and the conductive yarn 121. Between the conductive yarn 121 and the conductive yarn 121, and when the ground yarn 131 and the conductive yarn 121 are configured as an aggregate of single fibers such as multifilaments, they are present between the short fibers. Will be.
　また、導電性生地１０における導電部１２を構成する導電性糸１２１であって、生地の露出面側（被着体Ｚ側）に配置される導電性糸１２１に着目すると、図３～図５の模式断面図に示すように、当該導電性糸１２１の頂部よりも上方に配置される溶解前のシート状樹脂接着剤１５は（図３）、ヒートプレスによる加熱により溶解して矢印にて示すように、下方に流動していくと共に、加圧による被着体Ｚの移動によって導電性糸１２１の頂部近傍から押し出されていき（図４）、露出面側（被着体Ｚ側）に配置される導電性糸１２１と被着体Ｚとは互いに直接接触した状態で、両者が接続固定され、電気的な接続状態を得ることができる（図５）。 Further, when attention is paid to the conductive yarn 121 constituting the conductive portion 12 in the conductive fabric 10 and disposed on the exposed surface side (the adherend Z side) of the fabric, FIG. 3 to FIG. As shown in the schematic cross-sectional view of FIG. 3, the sheet-like resin adhesive 15 before melting, which is disposed above the top of the conductive yarn 121 (FIG. 3), is melted by heating with a heat press and indicated by an arrow. Thus, while flowing downward, the adherend Z is pushed from the vicinity of the top of the conductive yarn 121 by the movement of the adherend Z by pressurization (FIG. 4) and arranged on the exposed surface side (the adherend Z side). The electrically conductive yarn 121 and the adherend Z are in direct contact with each other and are connected and fixed to each other, so that an electrically connected state can be obtained (FIG. 5).
　また、ヒートプレス時における加圧力や加熱温度、加圧時間、加熱時間については、適宜設定すればよいが、例えば、比較的大きな加圧力を付与することにより、図６の模式断面図に示すように、導電部１２を構成する導電性糸１２１であって、少なくとも被着体Ｚと接触する部分の断面形状が、加圧方向に圧縮された扁平形状となるようにすることが好ましい、つまり、被着体Ｚと接触する導電性糸１２１部分の断面形状に関し、被着体Ｚの重ね合わせ方向に垂直な方向に沿う寸法（図６における左右方向の寸法）が、該重ね合わせ方向に沿う寸法（図６における上下方向の寸法）よりも大となる扁平形状となるようにすることが好ましい。なお、このような扁平形状を得る程度の加圧力を付与したまま、加熱温度を低下させていき樹脂接着剤を硬化させることにより、硬化した樹脂接着剤の保形性によって導電性糸１２１の所定部分における断面形状は、上述の扁平形状を維持することとなる。 Further, the pressing force, heating temperature, pressurizing time, and heating time at the time of heat press may be set as appropriate. For example, by applying a relatively large pressing force, as shown in the schematic cross-sectional view of FIG. Furthermore, it is preferable that the cross-sectional shape of the conductive yarn 121 constituting the conductive portion 12 and at least the portion in contact with the adherend Z is a flat shape compressed in the pressing direction, that is, Regarding the cross-sectional shape of the conductive yarn 121 portion in contact with the adherend Z, the dimension along the direction perpendicular to the overlay direction of the adherend Z (the dimension in the left-right direction in FIG. 6) is the dimension along the overlay direction. It is preferable to have a flat shape that is larger than (the vertical dimension in FIG. 6). It should be noted that, by applying a pressure sufficient to obtain such a flat shape, the heating temperature is lowered and the resin adhesive is cured, so that the conductive yarn 121 has a predetermined shape depending on the shape retention of the cured resin adhesive. The cross-sectional shape in the portion maintains the above-described flat shape.
　本発明に係る第１実施形態の導電性生地１０は、上述のように、導電部１２が配設される領域の少なくとも一部分において、導電性の被着体Ｚを導電部１２に直接接触させた状態で接続固定する樹脂接着剤が含浸される構造を有している。したがって、従来のように導電性接着剤を用いることなく、導電性を有しない接着剤を用いて導電性の被着体Ｚと導電性生地１０における導電部１２とを導通させることができ、接着剤の種類に関してその選択性が広がり、非常に汎用性に優れるものとなる。また、含浸された樹脂接着剤１５は、被着体Ｚとの接続部１４における導電部１２を構成する導電性糸１２１の周りにおいて当該導電性糸１２１をコーティングする部材として機能しつつ、被着体Ｚとの強固な接着作用をも奏することとなる。したがって、被着体Ｚと導電部１２との接続部分における導電性糸１２１が酸化することや当該導電性糸１２１の金属皮膜が脱落してしまうことを効果的に防止し、その劣化を抑制することが可能となり、被着体Ｚと導電部１２との良好な導通状態を維持することが可能となる。 As described above, in the conductive fabric 10 according to the first embodiment of the present invention, the conductive adherend Z is brought into direct contact with the conductive portion 12 in at least a part of the region where the conductive portion 12 is disposed. It has a structure that is impregnated with a resin adhesive that is connected and fixed in a state. Therefore, the conductive adherend Z and the conductive portion 12 in the conductive fabric 10 can be conducted with an adhesive having no conductivity without using a conductive adhesive as in the prior art. The selectivity with respect to the kind of the agent is widened, and it becomes very versatile. Further, the impregnated resin adhesive 15 functions as a member that coats the conductive yarn 121 around the conductive yarn 121 constituting the conductive portion 12 in the connection portion 14 with the adherend Z, and adheres to the adherend Z. A strong adhesive action with the body Z is also exhibited. Therefore, it is possible to effectively prevent the conductive yarn 121 at the connecting portion between the adherend Z and the conductive portion 12 from being oxidized and the metal film of the conductive yarn 121 from falling off, and suppress the deterioration. Therefore, it is possible to maintain a good conduction state between the adherend Z and the conductive portion 12.
　また、本発明に係る第１実施形態の導電性生地１０は、例えば、被着体Ｚを一旦取り外して洗濯等を行った後、再度被着体Ｚを設置する場合において、樹脂接着剤を別途準備する必要が無く、導電性生地１０に含浸された樹脂接着剤１５を再利用して両者を接続固定することが可能となる。つまり、接続部１４に被着体Ｚを重ね合わせた後、ヒートプレスを当該重ね合わせ部に施すことにより、既に導電性生地１０に含浸された樹脂接着剤１５が再度溶解し、被着体Ｚを導電性生地１０に固定することができる。 In addition, the conductive fabric 10 according to the first embodiment of the present invention has a resin adhesive separately when the adherend Z is installed again after the adherend Z is removed and washed, for example. There is no need to prepare, and it becomes possible to reuse and fix the resin adhesive 15 impregnated in the conductive fabric 10. That is, after the adherend Z is superimposed on the connection portion 14, the resin adhesive 15 already impregnated in the conductive fabric 10 is dissolved again by applying heat press to the overlap portion, and the adherend Z Can be fixed to the conductive fabric 10.
　また、本発明に係る導電性生地１０の導電部１２は導電性糸１２１からなる編地構造を有しており、また、非導電部１３も同様に地糸１３１からなる編地構造を有するように構成されている。このよう構造を採用することにより、溶解した樹脂接着剤が、生地の内部に含浸されやすく、また、含浸された樹脂接着剤１５を良好に保持でき、溶解した樹脂接着剤が、被着体Ｚが設けられる側とは反対側に大きく移動することを抑制することができる。 The conductive portion 12 of the conductive fabric 10 according to the present invention has a knitted fabric structure made of conductive yarn 121, and the non-conductive portion 13 similarly has a knitted fabric structure made of ground yarn 131. It is configured. By adopting such a structure, the dissolved resin adhesive is easily impregnated in the interior of the fabric, and the impregnated resin adhesive 15 can be satisfactorily held, and the dissolved resin adhesive is adhered to the adherend Z. It is possible to suppress a large movement to the side opposite to the side on which is provided.
　また、上述のように、被着体Ｚと接触する導電性糸１２１部分の断面形状に関し、被着体Ｚの重ね合わせ方向に垂直な方向に沿う寸法（図６における左右方向の寸法）が、該重ね合わせ方向に沿う寸法（図６における上下方向の寸法）よりも大となる扁平形状となるように構成することにより、導電部１２と被着体Ｚとの接触面積が増加し導電部１２と被着体Ｚとのより一層良好な電気的な接続状態を維持することが可能となる。また、導電部１２と被着体Ｚとの接触界面が、比較的フラットな形態となるため、例えば、一旦被着体Ｚを導電部１２から取り外した場合に、外部に露出している導電部１２の面積を大きくすることができる。したがって、再度、被着体Ｚを導電部１２上に設置してヒートプレスを行うことにより被着体Ｚを導電部１２に取り付ける際に、良好な導通状態を得やすくなるという利点も奏することとなる。 In addition, as described above, with respect to the cross-sectional shape of the conductive yarn 121 part in contact with the adherend Z, the dimension along the direction perpendicular to the overlay direction of the adherend Z (the dimension in the left-right direction in FIG. 6) is By configuring the flat shape to be larger than the dimension along the overlapping direction (the vertical dimension in FIG. 6), the contact area between the conductive portion 12 and the adherend Z is increased, and the conductive portion 12 is formed. It is possible to maintain an even better electrical connection state between and the adherend Z. In addition, since the contact interface between the conductive portion 12 and the adherend Z has a relatively flat shape, for example, when the adherend Z is once removed from the conductive portion 12, the conductive portion exposed to the outside. The area of 12 can be increased. Therefore, when the adherend Z is attached to the conductive portion 12 by placing the adherend Z on the conductive portion 12 and performing heat pressing again, there is also an advantage that it is easy to obtain a good conduction state. Become.

　次に、上記本発明に係る第２実施形態の導電性生地２０の製造方法について説明する。この導電性生地２０の製造方法は、図９のブロック図に示すように、繊維構造体形成ステップＳ１と、載置ステップＳ２と、加熱・加圧ステップＳ３とを備えている。 Next, a method for manufacturing the conductive fabric 20 according to the second embodiment of the present invention will be described. As shown in the block diagram of FIG. 9, the method for manufacturing the conductive fabric 20 includes a fiber structure forming step S1, a placing step S2, and a heating / pressing step S3.
　繊維構造体形成ステップＳ１は、上述の生地本体と当該生地本体の所定位置に形成された導電部２２とを備える繊維構造体２１を形成する工程である。繊維構造体２１の具体的な形成方法は、特に限定されないが、例えば、導電部２２を構成するための導電性糸２２１と、非導電部２３を構成するための非導電性の地糸２３１とを用いて、所定形状（例えば、長尺状（帯状）、筒形状、平面視矩形状、平面視円形状、衣類(シャツ、パンツ、ズボン、ベルト、靴下、手袋、帽子など)およびそれらの部材の形状の繊維構造体２１を製編する方法を挙げることができる。 The fiber structure forming step S1 is a process of forming a fiber structure 21 including the above-described fabric body and the conductive portion 22 formed at a predetermined position of the fabric body. Although the specific formation method of the fiber structure 21 is not specifically limited, For example, the electroconductive thread 221 for comprising the electroconductive part 22, and the nonelectroconductive ground yarn 231 for comprising the nonelectroconductive part 23, A predetermined shape (for example, long shape (band shape), cylindrical shape, rectangular shape in plan view, circular shape in plan view), clothing (shirt, pants, trousers, belt, socks, gloves, hat, etc.) and their members The method of knitting the fiber structure 21 having the shape of can be exemplified.
　載置ステップＳ２は、導電性材料及び樹脂を含むパターン導電層２５と、該パターン導電層２５の少なくとも一方の面側に配置される熱可塑性樹脂層２６とからなるプリント電極体２７を、繊維構造体２１における導電部２２の少なくとも一部分上に載置する工程である。 In the placing step S2, a printed electrode body 27 composed of a patterned conductive layer 25 containing a conductive material and a resin and a thermoplastic resin layer 26 disposed on at least one surface side of the patterned conductive layer 25 has a fiber structure. This is a step of placing on at least a part of the conductive portion 22 in the body 21.
　ここで、上記プリント電極体２７について説明する。このプリント電極体２７としては、図１０の断面図に示すように、離型フィルム２７１上に、印刷技術によりパターン導電層２５を形成した後、当該パターン導電層２５上に、熱可塑性樹脂層２６を配設して構成されるものを例示することができる。印刷技術としては特に限定されず、スクリーン印刷、グラビア印刷、凸版印刷、凹版印刷、グラビアオフセット印刷、インクジェット印刷や、フォトリソグラフィ等の細線パターニングなど、周知の印刷方法を用いることができる。熱可塑性樹脂層２６として、例えば、ポリウレタンを含有する樹脂を接着剤として採用する場合には、当該接着剤をパターン導電層２５上に塗布して構成することができる。また、パターン導電層２５上に配設される熱可塑性樹脂層２６の厚みは、１μｍ以上５０μｍ以下であることが好ましく、特に、５μｍ以上３０μｍ以下であることがより好ましい。熱可塑性樹脂層２６（接着剤）の厚みが１μｍ未満の場合、接着強度に問題がある。５０μｍより厚い場合、印刷で形成することが難しい。 Here, the printed electrode body 27 will be described. As shown in the sectional view of FIG. 10, the printed electrode body 27 is formed by forming a patterned conductive layer 25 on a release film 271 by a printing technique, and then forming a thermoplastic resin layer 26 on the patterned conductive layer 25. What is comprised and arrange | positioned can be illustrated. The printing technique is not particularly limited, and well-known printing methods such as screen printing, gravure printing, relief printing, intaglio printing, gravure offset printing, ink jet printing, and fine line patterning such as photolithography can be used. For example, when a resin containing polyurethane is used as the adhesive as the thermoplastic resin layer 26, the adhesive can be applied onto the pattern conductive layer 25. Further, the thickness of the thermoplastic resin layer 26 disposed on the pattern conductive layer 25 is preferably 1 μm or more and 50 μm or less, and more preferably 5 μm or more and 30 μm or less. When the thickness of the thermoplastic resin layer 26 (adhesive) is less than 1 μm, there is a problem in the adhesive strength. When it is thicker than 50 μm, it is difficult to form by printing.
　このようなプリント電極体２７を図１１に示すように、繊維構造体２１における導電部２２の少なくとも一部分上に、プリント電極体２７の熱可塑性樹脂層２６側を向けて載置することにより載置ステップＳ２は完了する。 As shown in FIG. 11, such a printed electrode body 27 is placed by placing the printed electrode body 27 on the thermoplastic resin layer 26 side on at least a part of the conductive portion 22 in the fiber structure 21. Step S2 is completed.
　加熱・加圧ステップＳ３は、繊維構造体２１上の所定位置に載置されたプリント電極体２７を加熱及び加圧することにより、プリント電極体２７の熱可塑性樹脂層２６を溶融させて繊維構造体２１の内部側に流動させて含浸させつつ、プリント電極体２７のパターン導電層２５を繊維構造体２１の表面凹凸形状に沿った状態で配置して導電部２２に電気的に接続する工程である。この加熱・加圧ステップＳ３において、導電性糸２２１の頂部よりも上方に配置される溶解前の熱可塑性樹脂層２６は、ヒートプレスによる加熱により溶解して下方に流動していくと共に、加圧によるパターン導電層２５の移動によって導電性糸２２１の頂部近傍から下方に押し出されていき、露出面側に配置される導電性糸２２１とパターン導電層２５とが互いに直接接触した状態で、また、地糸２３１とパターン導電層２５とが互いに直接接触した状態で接続固定される。なお、この加熱・加圧ステップＳ３が終了した後、プリント電極体２７における離型フィルム２７１を取り外すことにより、図８の断面図に示す本発明に係る導電性生地２０が形成される。 In the heating / pressurizing step S3, the printed electrode body 27 placed at a predetermined position on the fiber structure 21 is heated and pressed to melt the thermoplastic resin layer 26 of the printed electrode body 27, thereby causing the fiber structure. In this step, the patterned conductive layer 25 of the printed electrode body 27 is arranged along the surface irregularities of the fiber structure 21 and is electrically connected to the conductive portion 22 while being impregnated by flowing into the inner side of 21. . In this heating / pressurizing step S3, the unmelted thermoplastic resin layer 26 disposed above the top of the conductive yarn 221 is melted by heating by the heat press and flows downward, and is pressurized. The pattern conductive layer 25 is pushed downward from the vicinity of the top of the conductive yarn 221 by the movement of the conductive yarn 221, and the conductive yarn 221 disposed on the exposed surface side and the pattern conductive layer 25 are in direct contact with each other, The ground yarn 231 and the pattern conductive layer 25 are connected and fixed in a state of being in direct contact with each other. After the heating / pressurizing step S3 is completed, the release film 271 in the printed electrode body 27 is removed, thereby forming the conductive fabric 20 according to the present invention shown in the cross-sectional view of FIG.
　本発明に係る第２実施形態の導電性生地２０は、印刷技術により形成されるパターン導電層２５によって、導電性生地２０と外部装置との間の接続部構造を形成したものである。このパターン導電層２５は、例えば図８に示すように、導電性糸２２１及び地糸２３１を用いて製編されて形成される繊維構造体２１の露出表面（表面凹凸形状）に沿った状態で、断面視波状となるように配置されているため、パターン導電層２５と繊維構造体２１との密着性が高くなり、パターン導電層２５の断線、剥離等を効果的に防止することが可能となる。また導電部２２とパターン導電層２５との接触面積が大きくなるため、接触抵抗が低くなる。なお、本発明に係る導電性生地２０の場合、図１２（ａ）の画像に示すように、繊維構造体２１の露出表面に沿って、断線等を生じることなくパターン導電層２５が綺麗に形成されており、抵抗値不良や導通不良が発生することが防止されていることが分かる。一方、繊維構造体２１に直接印刷してパターン導電層２５を形成した場合、導電性材料及び樹脂からなる導電性ペーストが液状のため、図１２（ｂ）の画像に示すように、開口部（地糸２３１同士の隙間、導電性糸２２１同士の隙間、或いは、地糸２３１と導電性糸２２１との隙間）に導電性ペーストが落ち込んでしまい、断線や抵抗値不良が発生しやすくなる。ここで、図１２（ａ）における導電性生地２０は、ナイロン４０％及びポリエステル６０％の混合糸で編成された厚みが３００μｍの生地に対して、プリント電極体２７として、離型フィルム２７１上に厚み１０μｍのパターン導電層２５（銀ペースト）を形成し、当該パターン導電層２５上に、厚みが１０μｍのポリウレタン系接着剤（熱可塑性樹脂層２６）を配設したものを使用して上記方法により形成されている。また、図１２（ｂ）における導電性生地は、ナイロン４０％及びポリエステル６０％の混合糸で編成された厚みが３００μｍの生地に対して、直接、銀ペーストをその厚みが１０μｍとなるように設定して印刷したものである。 The conductive cloth 20 of the second embodiment according to the present invention is a structure in which a connection portion structure between the conductive cloth 20 and an external device is formed by a pattern conductive layer 25 formed by a printing technique. For example, as shown in FIG. 8, the patterned conductive layer 25 is in a state along the exposed surface (surface uneven shape) of the fiber structure 21 formed by knitting using the conductive yarn 221 and the ground yarn 231. Since it is arranged so as to have a cross-sectional wave shape, the adhesion between the pattern conductive layer 25 and the fiber structure 21 is increased, and it is possible to effectively prevent disconnection, peeling, and the like of the pattern conductive layer 25. Become. Further, since the contact area between the conductive portion 22 and the pattern conductive layer 25 is increased, the contact resistance is reduced. In the case of the conductive fabric 20 according to the present invention, as shown in the image of FIG. 12A, the pattern conductive layer 25 is neatly formed along the exposed surface of the fiber structure 21 without disconnection or the like. Thus, it can be seen that the occurrence of defective resistance and poor conduction is prevented. On the other hand, when the pattern conductive layer 25 is formed by printing directly on the fiber structure 21, since the conductive paste made of a conductive material and a resin is in a liquid state, as shown in the image of FIG. The conductive paste falls into the gaps between the ground yarns 231, the gaps between the conductive yarns 221, or the gaps between the ground yarns 231 and the conductive yarns 221, and breakage and poor resistance are likely to occur. Here, the conductive fabric 20 in FIG. 12A is formed on the release film 271 as a printed electrode body 27 with respect to a fabric having a thickness of 300 μm knitted with a mixed yarn of nylon 40% and polyester 60%. A patterned conductive layer 25 (silver paste) having a thickness of 10 μm is formed, and a polyurethane adhesive (thermoplastic resin layer 26) having a thickness of 10 μm is disposed on the patterned conductive layer 25 by the above method. Is formed. In addition, the conductive fabric in FIG. 12B is set so that the thickness of the silver paste is 10 μm directly on the fabric of 300 μm thickness knitted with a mixed yarn of 40% nylon and 60% polyester. Printed.
　また、パターン導電層２５と、繊維構造体２１における導電部２２とが一体化されて構成されるため、電気的な接合強度が強いという効果も発揮する。また、パターン導電層２５は、図８に示すように、繊維構造体２１の露出表面に沿って設けられているため、繊維構造体２１を構成する導電性糸２２１や地糸２３１との接触面積が大きいという特徴がある。これにより、パターン導電層２５が繊維構造体２１の表面から剥離してしまうことを、効果的に防止することが可能となる。 In addition, since the pattern conductive layer 25 and the conductive portion 22 in the fiber structure 21 are configured to be integrated, an effect of high electrical bonding strength is also exhibited. Moreover, since the pattern conductive layer 25 is provided along the exposed surface of the fiber structure 21 as shown in FIG. 8, the contact area with the conductive yarn 221 and the ground yarn 231 constituting the fiber structure 21. There is a feature that is large. Thereby, it becomes possible to prevent effectively that the pattern conductive layer 25 peels from the surface of the fiber structure 21.
　また、パターン導電層２５と繊維構造体２１における導電部２２とが一体化される際、熱可塑性樹脂層２６が繊維構造体２１の反対側の露出表面（パターン導電層２５が配置される露出表面とは反対側の表面）ににじみ出ない構成とすることが好ましい。本構成とすることで、熱可塑性樹脂層２６が導電性生地２０の反対側の露出表面より内側に存在するため、繊維構造体２１の反対側の風合いや肌触りを損なわない。 When the pattern conductive layer 25 and the conductive portion 22 in the fiber structure 21 are integrated, the thermoplastic resin layer 26 is exposed on the opposite side of the fiber structure 21 (exposed surface on which the pattern conductive layer 25 is disposed). It is preferable that the surface does not ooze out on the opposite surface. By setting it as this structure, since the thermoplastic resin layer 26 exists inside the exposed surface of the other side of the electroconductive fabric 20, the texture and touch of the other side of the fiber structure 21 are not impaired.
　また、本発明に係る第２実施形態の導電性生地２０は、繊維構造体２１における導電部２２よりもパターン幅やピッチを小さくすることができる。導電部２２のパターンは、その編成構造や糸径によって最小幅が規定されたり、導電糸の毛羽立ちによる短絡等の問題から隣接パターンとのピッチを小さくし難い。それに対し、パターン導電層２５は印刷技術により形成される為、線幅や線間ピッチを小さくすることが可能になる。特に、パターン導電層２５によって、導電性生地２０と外部装置との間の接続部構造を形成する場合に好適であり、導電性生地２０と外部装置との間の接続部構造における電極間距離を狭く形成することが可能となる。例えば、各配線間隔が３ｍｍの導電部２２に対し、本発明の構造でパターン導電層２５を接続することで、各配線間隔を０．２～１ｍｍ程度の狭ピッチに変換することができ、フラットケーブル(ＦＦＣやＦＰＣ)に使用されるような一般的なコネクタ（汎用のフラットケーブル用コネクタ）に直接挿入することも可能となる。例えば、導電性生地２０上に形成された心拍、心電あるいは筋電などの生体情報を測定する電極と、その測定データを処理する外部装置との間の接続が容易になる。 Further, the conductive fabric 20 of the second embodiment according to the present invention can be made smaller in pattern width and pitch than the conductive portion 22 in the fiber structure 21. The pattern of the conductive portion 22 has a minimum width defined by its knitting structure and yarn diameter, and it is difficult to reduce the pitch with the adjacent pattern due to problems such as a short circuit caused by fuzz of the conductive yarn. On the other hand, since the pattern conductive layer 25 is formed by a printing technique, the line width and the pitch between lines can be reduced. In particular, the pattern conductive layer 25 is suitable for forming a connection portion structure between the conductive fabric 20 and the external device, and the inter-electrode distance in the connection portion structure between the conductive fabric 20 and the external device is set. It becomes possible to form narrowly. For example, by connecting the pattern conductive layer 25 with the structure of the present invention to the conductive portion 22 with each wiring interval of 3 mm, each wiring interval can be converted to a narrow pitch of about 0.2 to 1 mm, It can be directly inserted into a general connector (general-purpose flat cable connector) used for a cable (FFC or FPC). For example, the connection between the electrode for measuring biological information such as heartbeat, electrocardiogram or myoelectricity formed on the conductive fabric 20 and the external device for processing the measurement data becomes easy.
　また、繊維構造体２１に含浸されている熱可塑性樹脂層２６は、パターン導電層２５と電気的に接続する導電部２２を構成する導電性糸２２１の周りにおいて当該導電性糸２２１をコーティングする部材として機能しつつ、パターン導電層２５との強固な接着作用をも奏することとなる。したがって、パターン導電層２５と導電部２２との接続部分における導電性糸２２１が酸化することや当該導電性糸２２１の金属皮膜が脱落してしまうことを効果的に防止し、その劣化を抑制することが可能となり、パターン導電層２５と導電部２２との良好な導通状態を維持することが可能となる。 The thermoplastic resin layer 26 impregnated in the fiber structure 21 is a member that coats the conductive yarn 221 around the conductive yarn 221 that constitutes the conductive portion 22 that is electrically connected to the pattern conductive layer 25. As a result, a strong adhesive action with the pattern conductive layer 25 is also exhibited. Therefore, it is possible to effectively prevent the conductive yarn 221 at the connecting portion between the pattern conductive layer 25 and the conductive portion 22 from being oxidized and the metal film of the conductive yarn 221 from falling off, and suppress the deterioration. Therefore, it is possible to maintain a good conduction state between the pattern conductive layer 25 and the conductive portion 22.
　また、本発明に係る第２実施形態の繊維構造体２１は、編地構造を有することが好ましい。この構造を採用することにより、溶解した熱可塑性樹脂が、導電性生地２０の開口から内部に含浸されやすく、また、含浸された熱可塑性樹脂を良好に保持できる。また、溶解した熱可塑性樹脂が、パターン導電層２５が設けられる側とは反対側に大きく移動することを抑制することができる。 Moreover, it is preferable that the fiber structure 21 of the second embodiment according to the present invention has a knitted fabric structure. By adopting this structure, the melted thermoplastic resin is easily impregnated into the inside from the opening of the conductive fabric 20, and the impregnated thermoplastic resin can be favorably retained. Moreover, it can suppress that the melt | dissolved thermoplastic resin moves largely to the opposite side to the side in which the pattern conductive layer 25 is provided.
　また、パターン導電層２５として、複数本が平行に配置された配線パターンを採用する場合に、例えば、図１３（ａ）に示すように、当該配線パターンを構成する配線２５１を有するパターン導電層２５を離型フィルム２７１上に形成する。このパターン導電層２５上に、熱可塑性樹脂層２６（例えば、ポリウレタンを含有する樹脂接着剤）をそれぞれの配線を覆うように（配線間は覆わないように）してプリント電極体２７を形成し、当該プリント電極体２７を繊維構造体２１上の所定位置に載置して加熱及び加圧することにより、導電性生地２０を構成する。このような導電性生地２０は、図１３（ｂ）に示すように、含浸される熱可塑性樹脂層２６が、各配線２５１の下方領域に存在し、配線２５１同士の間には存在しないように形成されるため、繊維構造体２１の通気性や柔軟性への影響を少なくできる。一方、図１３（ｃ）に示すように配線２５１間も熱可塑性樹脂層２６で覆うようにしてプリント電極体２７を形成して、導電性生地２０を構成した場合、配線パターンの耐久性や、高いパターン精度を確保することが可能となる。 Further, when a wiring pattern in which a plurality of patterns are arranged in parallel is adopted as the pattern conductive layer 25, for example, as shown in FIG. 13A, the pattern conductive layer 25 having a wiring 251 constituting the wiring pattern. Is formed on the release film 271. A printed electrode body 27 is formed on the patterned conductive layer 25 by covering the wirings with a thermoplastic resin layer 26 (for example, a resin adhesive containing polyurethane) so as not to cover the wirings. The conductive fabric 20 is configured by placing the printed electrode body 27 at a predetermined position on the fiber structure 21 and heating and pressing it. In such a conductive fabric 20, as shown in FIG. 13 (b), the thermoplastic resin layer 26 to be impregnated exists in the lower region of each wiring 251 and does not exist between the wirings 251. Therefore, the influence on the air permeability and flexibility of the fiber structure 21 can be reduced. On the other hand, when the conductive fabric 20 is formed by forming the printed electrode body 27 so as to cover the space between the wirings 251 with the thermoplastic resin layer 26 as shown in FIG. It is possible to ensure high pattern accuracy.
　以上、本発明に係る第２実施形態の導電性生地２０について説明したが、具体的構成は、上記実施形態に限定されない。例えば、上記第２実施形態において、図１４の模式断面図（図７に示す導電性生地２０の長手方向に沿った断面に対応）に示すように、パターン導電層２５の露出面を被覆する被覆体２８を備えるように構成してもよい。このような被覆体２８を設けるように構成することにより、パターン導電層２５の表面保護を図ることができ、導電性生地２０と外部装置との間の接続部構造であるパターン導電層２５の強度を向上させることができる。なお、外部装置との電気的な接続を考慮して、パターン導電層２５に対して繊維構造体２１側とは反対側の被覆体２８の一部を部分的に除去して、パターン導電層２５が露出するように構成する。ここで、被覆体２８として、例えば、樹脂フィルムや不織布、生地本体を構成する地糸２３１から形成した編地構造体等種々のものを採用することができる。被覆体２８をパターン導電層２５上に配設する手法は特に限定されず、例えば、上記熱可塑性樹脂層２６を形成する熱可塑性樹脂と同一の樹脂材料を介して熱融着させて配設することができる。また、上述の導電性生地２０を製造する方法で説明した転写フィルムを被覆体２８として活用することもできる。更に、樹脂によるコーティング層を被覆体２８とすることもできる。 The conductive fabric 20 according to the second embodiment of the present invention has been described above, but the specific configuration is not limited to the above embodiment. For example, in the second embodiment, as shown in the schematic cross-sectional view of FIG. 14 (corresponding to the cross-section along the longitudinal direction of the conductive fabric 20 shown in FIG. 7), the coating covering the exposed surface of the pattern conductive layer 25 You may comprise so that the body 28 may be provided. By providing such a covering 28, the surface of the patterned conductive layer 25 can be protected, and the strength of the patterned conductive layer 25 which is a connection structure between the conductive fabric 20 and the external device. Can be improved. In consideration of electrical connection with an external device, the pattern conductive layer 25 is partially removed by partially removing the covering 28 on the side opposite to the fiber structure 21 side with respect to the pattern conductive layer 25. Is configured to be exposed. Here, as the covering body 28, various things, such as a knitted fabric structure formed from the ground yarn 231 which comprises a resin film, a nonwoven fabric, and a fabric main body, are employable, for example. The method for disposing the covering 28 on the pattern conductive layer 25 is not particularly limited. For example, the covering 28 is heat-sealed and disposed via the same resin material as the thermoplastic resin forming the thermoplastic resin layer 26. be able to. Moreover, the transfer film demonstrated by the method of manufacturing the above-mentioned conductive fabric 20 can also be utilized as the covering 28. Further, a coating layer made of a resin can be used as the covering 28.
　また、上記第２実施形態においては、熱可塑性樹脂層２６が、パターン導電層２５に対して繊維構造体２１側に設けられるように構成しているが、このような形態に特に限定されず、図１５や図１６の模式断面図に示すように、パターン導電層２５に対して、繊維構造体２１側とは反対側に熱可塑性樹脂層２６の一部が設けられるような構成を採用することもできる。このような構成の場合、外部装置との電気的な接続を考慮して、パターン導電層２５に対して繊維構造体２１側とは反対側の熱可塑性樹脂層２６の一部を部分的に除去して、パターン導電層２５が露出するように構成する。この図１５や図１６に示す構成の場合、パターン導電層２５の露出面が熱可塑性樹脂層２６によって被覆される形態となり、パターン導電層２５の表面保護を図ることができる。 Further, in the second embodiment, the thermoplastic resin layer 26 is configured to be provided on the fiber structure 21 side with respect to the pattern conductive layer 25, but is not particularly limited to such a form, As shown in the schematic cross-sectional views of FIGS. 15 and 16, a configuration in which a part of the thermoplastic resin layer 26 is provided on the side opposite to the fiber structure 21 side with respect to the pattern conductive layer 25 is adopted. You can also. In such a configuration, in consideration of electrical connection with an external device, a part of the thermoplastic resin layer 26 on the side opposite to the fiber structure 21 side with respect to the pattern conductive layer 25 is partially removed. Then, the pattern conductive layer 25 is configured to be exposed. In the case of the configuration shown in FIGS. 15 and 16, the exposed surface of the pattern conductive layer 25 is covered with the thermoplastic resin layer 26, so that the surface of the pattern conductive layer 25 can be protected.
　また、上記第２実施形態において、図１７に示すように、繊維構造体２１が、導電部２２が設けられる生地本体と、部分的に突出する生地片２９とを備えるように構成し、かつ、熱可塑性樹脂層２６及びパターン導電層２５の少なくとも一部分が、該生地片２９に配置されるように構成してもよい。なお、この生地片２９は、非導電性の地糸２３１から形成することができる。このような生地片２９を設けることにより、図１８（ａ）（ｂ）の模式図に示すように、外部装置における電気信号取得用のコネクタ１００に直接的に挿入して接続することが可能となる。なお、図１８（ｂ）は、図１８（ａ）の断面に対応する模式図である。 Moreover, in the said 2nd Embodiment, as shown in FIG. 17, the fiber structure 21 is comprised so that it may be provided with the fabric main body in which the electroconductive part 22 is provided, and the fabric piece 29 which protrudes partially, and, You may comprise so that at least one part of the thermoplastic resin layer 26 and the pattern conductive layer 25 may be arrange | positioned at this fabric piece 29. FIG. The fabric piece 29 can be formed from a non-conductive ground yarn 231. By providing such a fabric piece 29, as shown in the schematic diagrams of FIGS. 18 (a) and 18 (b), it can be directly inserted and connected to the connector 100 for acquiring an electric signal in the external device. Become. FIG. 18B is a schematic diagram corresponding to the cross section of FIG.
　また、図１７に示すように生地片２９を設ける場合には、図１８（ｂ）に示すように、当該生地片２９に補強部材２９１を設けるように構成してもよい。補強部材２９１は、生地片２９上においてパターン導電層２５が配置される面とは反対側の面であって、生地片２９の先端部分に配置されることが好ましい。なお、補強部材２９１をパターン導電層２５の露出面上に設けるようにしてもよい。このような場合、外部装置との電気的な接続を考慮して、補強部材２９１の一部を部分的に除去して、パターン導電層２５が露出するように構成する。また、補強部材２９１としては、例えば、樹脂フィルムや不織布、生地本体を構成する地糸２３１から形成した編地構造体等種々のものを採用することができる。また、樹脂によるコーティング層を補強部材２９１とすることもできる。このような補強部材２９１を設けることにより、生地片２９の先端側の剛性を高めることができるため、外部装置における電気信号取得用のコネクタ１００に生地片２９を挿入しやすくなるという効果を得ることができる。また、補強部材２９１の厚みを適宜設定して生地片の先端部分の厚み寸法を、コネクタ１００における挿入孔の厚み方向寸法と同程度に構成することにより、コネクタ１００に挿入された生地片２９の先端部が、挿入孔内で浮いてしまうことを防止して、しっかりと固定させることが可能となる。 Further, when the dough piece 29 is provided as shown in FIG. 17, a reinforcing member 291 may be provided on the dough piece 29 as shown in FIG. It is preferable that the reinforcing member 291 is disposed on the front end portion of the fabric piece 29 on the opposite side of the surface on which the pattern conductive layer 25 is disposed on the fabric piece 29. Note that the reinforcing member 291 may be provided on the exposed surface of the patterned conductive layer 25. In such a case, in consideration of electrical connection with an external device, a part of the reinforcing member 291 is partially removed so that the pattern conductive layer 25 is exposed. Moreover, as the reinforcing member 291, various things, such as a knitted fabric structure formed from the ground yarn 231 which comprises a resin film, a nonwoven fabric, and a fabric main body, are employable, for example. Further, a resin coating layer can be used as the reinforcing member 291. By providing such a reinforcing member 291, the rigidity on the distal end side of the fabric piece 29 can be increased, so that the effect of facilitating the insertion of the fabric piece 29 into the electrical signal acquisition connector 100 in the external device is obtained. Can do. Further, by setting the thickness of the reinforcing member 291 as appropriate and making the thickness dimension of the tip portion of the fabric piece approximately the same as the thickness direction dimension of the insertion hole in the connector 100, the fabric piece 29 inserted into the connector 100 It is possible to prevent the tip portion from floating in the insertion hole and fix it firmly.
　また、生地片２９を設ける場合、図１９の模式断面図に示すように、生地片２９が、生地本体（繊維構造体２１）の表面から外方に突出するように形成してもよい。このような形態を採用することにより、例えば、繊維構造体２１を衣類形体状(シャツ形やズボン形など)に形成する場合であっても、そのデザイン性の自由度が高まり、また、外部装置との接続部構造である生地片２９が着用者にとって邪魔になってしまうことを効果的に抑制することが可能となる。なお、このような効果は、繊維構造体２１を衣類形体状(シャツ形やズボン形など)に形成する場合に限らず、図７に示すように長尺状に導電性生地２０を構成し、例えば、心電図や筋電図等のデータ採取、或いは電気治療や電磁波治療などを対象者に対して行う場合に、対象者の腕や脚、胴部などに巻きつけて装着する場合であっても同様である。 Further, when the fabric piece 29 is provided, as shown in the schematic cross-sectional view of FIG. 19, the fabric piece 29 may be formed so as to protrude outward from the surface of the fabric body (fiber structure 21). By adopting such a configuration, for example, even when the fiber structure 21 is formed in a clothing shape (such as a shirt shape or a trouser shape), the degree of freedom in design is increased, and the external device It is possible to effectively suppress the fabric piece 29 having the connecting portion structure from becoming an obstacle to the wearer. Such an effect is not limited to the case where the fiber structure 21 is formed in a clothing shape (such as a shirt shape or a trouser shape), but the conductive fabric 20 is configured in a long shape as shown in FIG. For example, when collecting data such as an electrocardiogram or electromyogram, or performing electrical treatment or electromagnetic wave treatment on the subject, even if it is wrapped around the subject's arm, leg, trunk, etc. It is the same.
　また、上記第２実施形態において、繊維構造体２１における導電部２２の少なくとも一部分が、図２０の模式断面図に示すように、繊維構造体２１においてパターン導電層２５が設けられる面とは反対側の面に露出するように構成してもよい。このような形態を採用することにより、例えば、心電図や筋電図等のデータ採取、或いは電気治療などを行う場合に、反対側の面に露出した導電部２２が電極として機能する。導電性生地２０を対象者の腕や脚、胴部などに巻きつけて装着する場合に、対象者の身体の表面に導電部２２を密着させつつ、装着された導電性生地２０の外表面側に外部装置との接続部構造であるパターン導電層２５が露出することになるため、使用上の簡便性を確保しつつ、確実に生体信号の取得等を行うことが可能となる。 In the second embodiment, at least a part of the conductive portion 22 in the fiber structure 21 is opposite to the surface on which the pattern conductive layer 25 is provided in the fiber structure 21 as shown in the schematic cross-sectional view of FIG. You may comprise so that it may be exposed to the surface. By adopting such a form, for example, when collecting data such as an electrocardiogram or an electromyogram, or performing electrotherapy, the conductive portion 22 exposed on the opposite surface functions as an electrode. When the conductive fabric 20 is wrapped around the subject's arm, leg, torso or the like, the conductive fabric 22 is brought into close contact with the surface of the subject's body while the conductive fabric 20 is mounted on the outer surface side. In addition, since the pattern conductive layer 25 which is a connection portion structure with an external device is exposed, it is possible to reliably acquire a biological signal while ensuring ease of use.
　また、上述した第２実施形態の導電性生地２０に係る製造方法は、プリント電極体２７における熱可塑性樹脂層２６及びパターン導電層２５を繊維構造体２１に転写することにより導電性生地２０を形成する方法であるが、このような転写技術を利用する他、以下のような方法によっても導電性生地２０を形成することができる。すなわち、図２１に示すように、フィルム状の熱可塑性樹脂層２６上に、印刷技術によりパターン導電層２５を形成することによりプリント電極体２７を形成し、繊維構造体２１における導電部２２の少なくとも一部分上に、このプリント電極体２７の熱可塑性樹脂層２６側を向けて載置し（載置ステップＳ２）、その後、上記加熱・加圧ステップＳ３における工程を施すことにより、フィルム状の熱可塑性樹脂層２６を溶融させて繊維構造体２１に含浸させつつ、パターン導電層２５を繊維構造体２１の表面に設けるようにしてもよい。なお、フィルム状の熱可塑性樹脂層２６の厚みは、１０μｍ以上１００μｍ以下であることが好ましく、特に、２０μｍ以上８０μｍ以下であることがより好ましい。フィルム状の熱可塑性樹脂層２６の厚みが１０μｍ未満の場合、強度や取扱い性に問題がある。１００μｍより厚い場合、コストが高くなり、また導電性生地２０に十分な厚みがないと熱可塑性樹脂が裏面へにじみ出るおそれがある。 Moreover, the manufacturing method according to the conductive fabric 20 of the second embodiment described above forms the conductive fabric 20 by transferring the thermoplastic resin layer 26 and the pattern conductive layer 25 in the printed electrode body 27 to the fiber structure 21. However, in addition to using such a transfer technique, the conductive fabric 20 can be formed by the following method. That is, as shown in FIG. 21, a printed electrode body 27 is formed by forming a patterned conductive layer 25 on a film-like thermoplastic resin layer 26 by a printing technique, and at least the conductive portions 22 in the fiber structure 21 are formed. On the part, the printed electrode body 27 is placed with the thermoplastic resin layer 26 side facing (placement step S2), and then the process in the heating / pressurizing step S3 is performed, thereby forming a film-like thermoplasticity. The pattern conductive layer 25 may be provided on the surface of the fiber structure 21 while the resin layer 26 is melted and impregnated in the fiber structure 21. The thickness of the film-like thermoplastic resin layer 26 is preferably 10 μm or more and 100 μm or less, and more preferably 20 μm or more and 80 μm or less. When the thickness of the film-like thermoplastic resin layer 26 is less than 10 μm, there is a problem in strength and handleability. If it is thicker than 100 μm, the cost increases, and if the conductive fabric 20 does not have a sufficient thickness, the thermoplastic resin may ooze out to the back surface.
　上記フィルム状の熱可塑性樹脂層２６は、上述した熱可塑性樹脂層２６を構成する樹脂から形成することができるが、特にポリウレタン樹脂製のフィルムを熱可塑性樹脂層２６として採用することが好ましい。繊維構造体２１に含浸されたポリウレタン樹脂製のフィルムの厚み（量）が大きくなると、繊維構造体２１における含浸領域が僅かに固くなるため、パターン導電層２５が形成される導電性生地２０部分の強度を向上させることが可能となる。例えば、外部装置との接続部として用いる場合、端子間の幅精度を確保するために本構造を用いることが好ましい。 The film-like thermoplastic resin layer 26 can be formed from the resin constituting the thermoplastic resin layer 26 described above, and it is particularly preferable to employ a polyurethane resin film as the thermoplastic resin layer 26. When the thickness (amount) of the polyurethane resin film impregnated in the fiber structure 21 is increased, the impregnation region in the fiber structure 21 is slightly hardened, so that the conductive fabric 20 portion where the pattern conductive layer 25 is formed is formed. Strength can be improved. For example, when used as a connection portion with an external device, it is preferable to use this structure in order to ensure the width accuracy between terminals.
　また、上記第２実施形態においては、パターン導電層２５が、導電性生地２０と外部装置との間の接続部構造を構成するように形成されているが、このような構成に特に限定されず、例えば、図２２の平面図に示すように、導電部２２同士を電気的に接続する接続部構造としてパターン導電層２５を用いることもできる。例えば、繊維構造体２１が編地構造を有し、導電性生地２０の導電部２２が導電性糸２２１を編み込んで形成される場合、編成方向に長い導電部２２の配線パターンを形成することは製造上容易である。しかし、編成方向に対し垂直または斜め方向の導電部２２の配線パターンを形成する場合は、編成ライン毎に導電性糸２２１と非導電性の地糸２３１の切替えが必要となり、煩雑な工程となる。そこで、上記のように、パターン導電層２５で導電部２２同士を接続する構成を採用することで、導電性生地２０上の配線等のパターニングの自由度が向上する。 Moreover, in the said 2nd Embodiment, although the pattern conductive layer 25 is formed so that the connection part structure between the conductive cloth 20 and an external device may be comprised, it is not specifically limited to such a structure. For example, as shown in the plan view of FIG. 22, the pattern conductive layer 25 can be used as a connection portion structure for electrically connecting the conductive portions 22 to each other. For example, when the fiber structure 21 has a knitted fabric structure and the conductive portion 22 of the conductive fabric 20 is formed by weaving the conductive yarn 221, forming a wiring pattern of the conductive portion 22 that is long in the knitting direction is Easy to manufacture. However, when forming the wiring pattern of the conductive portion 22 perpendicular or oblique to the knitting direction, it is necessary to switch between the conductive yarn 221 and the non-conductive ground yarn 231 for each knitting line, which is a complicated process. . Therefore, by adopting a configuration in which the conductive portions 22 are connected to each other by the patterned conductive layer 25 as described above, the degree of freedom of patterning of the wiring and the like on the conductive fabric 20 is improved.
　また、上記第２実施形態において説明した導電性生地２０の製造方法においては、離型フィルム２７１上に、印刷技術によりパターン導電層２５を形成した後、当該パターン導電層２５上に、熱可塑性樹脂層２６を配設して構成されるプリント電極体２７を用い、このプリント電極体２７におけるパターン導電層２５及び熱可塑性樹脂層２６を繊維構造体２１に転写するようにしているが、このような手法の他、離型フィルム２７１上に印刷技術によりパターン導電層２５を形成してプリント電極体２７を構成し、例えば、シート状、液状、粉状、或いは、粒状の熱可塑性樹脂を、繊維構造体２１における導電部２２の少なくとも一部分上に塗布又は配置した上で、当該プリント電極体２７を載置し、加熱・加圧ステップＳ３によるヒートプレスを行うようにして、シート状、液状、粉状、或いは、粒状の熱可塑性樹脂を溶融させて繊維構造体２１に含浸させつつ、パターン導電層２５を繊維構造体２１の表面に設けるようにしてもよい。なお、ヒートプレスを、繊維構造体２１の形状を保ちつつ、繊維構造体２１の露出表面にパターン導電層２５が密着する加熱・加圧条件とすることで、生地の風合いを損なわない。 Further, in the method for manufacturing the conductive fabric 20 described in the second embodiment, after the pattern conductive layer 25 is formed on the release film 271 by a printing technique, the thermoplastic resin is formed on the pattern conductive layer 25. A printed electrode body 27 configured by disposing the layer 26 is used, and the pattern conductive layer 25 and the thermoplastic resin layer 26 in the printed electrode body 27 are transferred to the fiber structure 21. In addition to the method, the pattern conductive layer 25 is formed on the release film 271 by a printing technique to form the printed electrode body 27. For example, a sheet-like, liquid, powdery, or granular thermoplastic resin is used as a fiber structure. After applying or arranging on at least a part of the conductive portion 22 in the body 21, the printed electrode body 27 is placed, and heating by the heating / pressurizing step S3 is performed. The pattern conductive layer 25 is provided on the surface of the fiber structure 21 while melting the sheet-like, liquid, powdery, or granular thermoplastic resin and impregnating the fiber structure 21. May be. In addition, the texture of cloth | dough is not impaired by making heat press into the heating and pressurization conditions which the pattern conductive layer 25 closely_contact | adheres to the exposed surface of the fiber structure 21, maintaining the shape of the fiber structure 21.

However, the fiber structure 31 is not particularly limited to such a form. For example, a tubular shape (straight or tapered) Or a rectangular shape in plan view, or a circular shape in plan view. Moreover, you may comprise the fiber structure 31 as clothing, such as a shirt, pants, trousers, socks, gloves, and a hat. In FIG. 23, each wiring 32 is formed in a narrow strip shape along the longitudinal direction of the fiber structure 31, and each non-conductive portion 33 is also formed in a narrow strip shape along the longitudinal direction of the fiber structure 31. However, it is not particularly limited to such a form, and the wiring 32 and the non-conductive portion 33 can be configured to have various shapes according to the purpose of use of the conductive fabric 30 or the mounting location. Further, the numbers of the wirings 32 and the non-conductive portions 33 are not particularly limited, and can be changed as appropriate.

In addition, the part comprised by the nonelectroconductive ground yarn 331 comprises the fabric main body in the fiber structure 31. Further, the manufacturing method of the fiber structure 31 is not limited to the above method.

　載置ステップＳ２は、導電性材料及び樹脂を含むパターン導電層３５と、該パターン導電層３５の少なくとも一方の面側に配置される熱可塑性樹脂層３６とからなるプリント電極体３７を、端子部３４に対応する位置において、繊維構造体３１における配線３２の少なくとも一部分上にパターン導電層３５が重なるようにして載置する工程である。 The placing step S2 includes a printed electrode body 37 comprising a patterned conductive layer 35 containing a conductive material and a resin and a thermoplastic resin layer 36 disposed on at least one surface side of the patterned conductive layer 35. In this step, the pattern conductive layer 35 is placed on at least a part of the wiring 32 in the fiber structure 31 at a position corresponding to 34.
　ここで、上記プリント電極体３７について説明する。このプリント電極体３７としては、図２６の断面図に示すように、離型フィルム３７１上に、印刷技術によりパターン導電層３５を形成した後、当該パターン導電層３５上に、熱可塑性樹脂層３６を配設して構成されるものを例示することができる。印刷技術としては特に限定されず、スクリーン印刷、グラビア印刷、凸版印刷、凹版印刷、グラビアオフセット印刷、インクジェット印刷や、フォトリソグラフィ等の細線パターニングなど、周知の印刷方法を用いることができる。熱可塑性樹脂層３６として、例えば、ポリウレタンを含有する樹脂を接着剤として採用する場合には、当該接着剤をパターン導電層３５上に塗布して構成することができる。また、パターン導電層３５上に配設される熱可塑性樹脂層３６の厚みは、１μｍ以上５０μｍ以下であることが好ましく、特に、５μｍ以上３０μｍ以下であることがより好ましい。熱可塑性樹脂層３６（接着剤）の厚みが１μｍ未満の場合、接着強度に問題がある。５０μｍより厚い場合、印刷で形成することが難しい。 Here, the printed electrode body 37 will be described. As shown in the cross-sectional view of FIG. 26, the printed electrode body 37 is formed by forming a patterned conductive layer 35 on a release film 371 by a printing technique, and then forming a thermoplastic resin layer 36 on the patterned conductive layer 35. What is comprised and arrange | positioned can be illustrated. The printing technique is not particularly limited, and well-known printing methods such as screen printing, gravure printing, relief printing, intaglio printing, gravure offset printing, ink jet printing, and fine line patterning such as photolithography can be used. For example, when a resin containing polyurethane is used as the adhesive as the thermoplastic resin layer 36, the adhesive can be applied to the pattern conductive layer 35. In addition, the thickness of the thermoplastic resin layer 36 disposed on the pattern conductive layer 35 is preferably 1 μm or more and 50 μm or less, and more preferably 5 μm or more and 30 μm or less. When the thickness of the thermoplastic resin layer 36 (adhesive) is less than 1 μm, there is a problem in the adhesive strength. When it is thicker than 50 μm, it is difficult to form by printing.
　このようなプリント電極体３７を図２７に示すように、繊維構造体３１における配線３２の少なくとも一部分上に、プリント電極体３７の熱可塑性樹脂層３６側を向けて載置することにより載置ステップＳ２は完了する。 As shown in FIG. 27, such a printed electrode body 37 is placed on at least a part of the wiring 32 in the fiber structure 31 by placing the printed electrode body 37 facing the thermoplastic resin layer 36 side. S2 is completed.
　加熱・加圧ステップＳ３は、繊維構造体３１上の所定位置（端子部３４を形成する位置）に載置されたプリント電極体３７を加熱及び加圧することにより、プリント電極体３７の熱可塑性樹脂層３６を溶融させて繊維構造体３１の内部側に流動させて含浸させつつ、プリント電極体３７のパターン導電層３５を繊維構造体３１の表面凹凸形状に沿った状態で配置して配線３２に電気的に接続する工程である。この加熱・加圧ステップＳ３において、導電性糸３２１の頂部よりも上方に配置される溶解前の熱可塑性樹脂層３６は、ヒートプレスによる加熱により溶解して下方に流動していくと共に、加圧によるパターン導電層３５の移動によって導電性糸３２１の頂部近傍から下方に押し出されていき、露出面側に配置される導電性糸３２１とパターン導電層３５とが互いに直接接触した状態で、また、地糸３３１とパターン導電層３５とが互いに直接接触した状態で接続固定される。なお、この加熱・加圧ステップＳ３が終了した後、プリント電極体３７における離型フィルム３７１を取り外すことにより、図２４の断面図に示す本発明に係る導電性生地３０が形成される。 The heating / pressurizing step S3 heats and pressurizes the printed electrode body 37 placed at a predetermined position (position where the terminal portion 34 is formed) on the fiber structure 31, thereby the thermoplastic resin of the printed electrode body 37. The pattern conductive layer 35 of the printed electrode body 37 is arranged along the surface irregularities of the fiber structure 31 while being melted and flown and impregnated inside the fiber structure 31 to the wiring 32. This is an electrical connection process. In this heating / pressurizing step S3, the unmelted thermoplastic resin layer 36 disposed above the top of the conductive yarn 321 is melted by heating by a heat press and flows downward, and is pressurized. The pattern conductive layer 35 is pushed downward from the vicinity of the top of the conductive thread 321 by the movement of the conductive thread 321, and the conductive thread 321 disposed on the exposed surface side and the pattern conductive layer 35 are in direct contact with each other, The ground yarn 331 and the pattern conductive layer 35 are connected and fixed in a state of being in direct contact with each other. After the heating / pressurizing step S3 is completed, the release film 371 in the printed electrode body 37 is removed, thereby forming the conductive cloth 30 according to the present invention shown in the sectional view of FIG.
　本発明に係る第３実施形態の導電性生地３０は、フラットケーブル(ＦＦＣやＦＰＣ)に使用される一般的なコネクタ（汎用のフラットケーブル用コネクタ）に直接挿入することが可能な端子部３４を備えているため、外部装置の有する外部デバイス回路のコネクタと直接的に接続できる。つまり、導電性生地３０にＦＰＣ等の接続配線を別途設けることなく、端子部３４を介して、外部デバイス回路との電気信号の入出力が可能となる。 The conductive fabric 30 according to the third embodiment of the present invention has a terminal portion 34 that can be directly inserted into a general connector (general-purpose flat cable connector) used in a flat cable (FFC or FPC). Since it is provided, it can be directly connected to the connector of the external device circuit of the external device. That is, it is possible to input / output an electric signal to / from an external device circuit via the terminal portion 34 without separately providing connection wiring such as FPC on the conductive fabric 30.
　また、本発明に係る第３実施形態の導電性生地３０は、印刷技術により形成されるパターン導電層３５によって、導電性生地３０と外部装置との間の接続部構造を形成したものである。このパターン導電層３５は、例えば図２４に示すように、導電性糸３２１及び地糸３３１を用いて製編されて形成される繊維構造体３１の露出表面（表面凹凸形状）に沿った状態で、断面視波状となるように配置されているため、パターン導電層３５と繊維構造体３１との密着性が高くなり、パターン導電層３５の断線、剥離等を効果的に防止することが可能となる。また配線３２とパターン導電層３５との接触面積が大きくなるため、接触抵抗が低くなる。なお、第３実施形態に係る導電性生地３０の場合、図２８（ａ）の画像に示すように、繊維構造体３１の露出表面に沿って、断線等を生じることなくパターン導電層３５が綺麗に形成されており、抵抗値不良や導通不良が発生することが防止されていることが分かる。一方、繊維構造体３１に直接印刷してパターン導電層３５を形成した場合、導電性材料及び樹脂からなる導電性ペーストが液状のため、図２８（ｂ）の画像に示すように、開口部（地糸３３１同士の隙間、導電性糸３２１同士の隙間、或いは、地糸３３１と導電性糸３２１との隙間）に導電性ペーストが落ち込んでしまい、断線や抵抗値不良が発生しやすくなる。ここで、図２８（ａ）における導電性生地３０は、ナイロン４０％及びポリエステル６０％の混合糸で編成された厚みが３００μｍの生地に対して、プリント電極体３７として、離型フィルム３７１上に厚み１０μｍのパターン導電層３５（銀ペースト）を形成し、当該パターン導電層３５上に、厚みが１０μｍのポリウレタン系接着剤（熱可塑性樹脂層３６）を配設したものを使用して上記方法により形成されている。また、図２８（ｂ）における導電性生地は、ナイロン４０％及びポリエステル６０％の混合糸で編成された厚みが３００μｍの生地に対して、直接、銀ペーストをその厚みが１０μｍとなるように設定して印刷したものである。 In addition, the conductive cloth 30 of the third embodiment according to the present invention is formed by forming a connection portion structure between the conductive cloth 30 and the external device by the pattern conductive layer 35 formed by a printing technique. For example, as shown in FIG. 24, the pattern conductive layer 35 is in a state along the exposed surface (surface uneven shape) of the fiber structure 31 formed by knitting and knitting using the conductive yarn 321 and the ground yarn 331. Since the arrangement is such that the cross-sectional view is wave-like, the adhesion between the pattern conductive layer 35 and the fiber structure 31 is increased, and it is possible to effectively prevent disconnection, peeling, and the like of the pattern conductive layer 35. Become. Further, since the contact area between the wiring 32 and the pattern conductive layer 35 is increased, the contact resistance is decreased. In the case of the conductive fabric 30 according to the third embodiment, as shown in the image of FIG. 28A, the patterned conductive layer 35 is clean along the exposed surface of the fiber structure 31 without causing disconnection or the like. It can be seen that the resistance value failure and the conduction failure are prevented from occurring. On the other hand, when the pattern conductive layer 35 is formed by printing directly on the fiber structure 31, since the conductive paste made of the conductive material and the resin is liquid, as shown in the image of FIG. The conductive paste falls into the gaps between the ground yarns 331, the gaps between the conductive yarns 321 or the gaps between the ground yarns 331 and the conductive yarns 321), and disconnection and resistance value defects are likely to occur. Here, the conductive fabric 30 in FIG. 28A is formed on a release film 371 as a printed electrode body 37 with respect to a fabric having a thickness of 300 μm knitted with a mixed yarn of nylon 40% and polyester 60%. A patterned conductive layer 35 (silver paste) having a thickness of 10 μm is formed, and a polyurethane adhesive (thermoplastic resin layer 36) having a thickness of 10 μm is disposed on the patterned conductive layer 35 by the above method. Is formed. In addition, the conductive fabric in FIG. 28B is set so that the thickness of the silver paste is 10 μm directly on the fabric of 300 μm thickness knitted with a mixed yarn of 40% nylon and 60% polyester. Printed.
　また、パターン導電層３５と、繊維構造体３１における配線３２とが一体化されて構成されるため、電気的な接合強度が強いという効果も発揮する。また、パターン導電層３５は、図２４に示すように、繊維構造体３１の露出表面に沿って設けられているため、繊維構造体３１を構成する導電性糸３２１や地糸３３１との接触面積が大きいという特徴がある。これにより、パターン導電層３５が繊維構造体３１の表面から剥離してしまうことを、効果的に防止することが可能となる。 In addition, since the pattern conductive layer 35 and the wiring 32 in the fiber structure 31 are integrated, the effect of high electrical bonding strength is also exhibited. Moreover, since the pattern conductive layer 35 is provided along the exposed surface of the fiber structure 31, as shown in FIG. 24, the contact area with the conductive yarn 321 and the ground yarn 331 which comprise the fiber structure 31 is provided. There is a feature that is large. Thereby, it becomes possible to prevent effectively that the pattern conductive layer 35 peels from the surface of the fiber structure 31.
　また、パターン導電層３５と繊維構造体３１における配線３２とが一体化される際、熱可塑性樹脂層３６が繊維構造体３１の反対側の露出表面（パターン導電層３５が配置される露出表面とは反対側の表面）ににじみ出ない構成とすることが好ましい。本構成とすることで、熱可塑性樹脂層３６が導電性生地３０の反対側の露出表面より内側に存在するため、繊維構造体３１の反対側の風合いや肌触りを損なわない。 Further, when the pattern conductive layer 35 and the wiring 32 in the fiber structure 31 are integrated, the thermoplastic resin layer 36 is exposed on the opposite side of the fiber structure 31 (the exposed surface on which the pattern conductive layer 35 is disposed). It is preferable that the surface does not ooze out on the opposite surface. By setting it as this structure, since the thermoplastic resin layer 36 exists inside the exposed surface of the other side of the electroconductive fabric 30, the texture and touch of the other side of the fiber structure 31 are not impaired.
　また、本発明に係る第３実施形態の導電性生地３０は、繊維構造体３１における導電性糸３２１で形成された配線３２のパターン幅やピッチよりもパターン導電層３５のパターン幅やピッチを小さくすることができる。配線３２のパターンは、その編成構造や糸径によって最小幅が規定されたり、導電糸の毛羽立ちによる短絡等の問題から隣接パターンとのピッチを小さくし難い。それに対し、パターン導電層３５は印刷技術により形成される為、線幅や線間ピッチを小さくすることが可能になる。特に、パターン導電層３５によって、導電性生地３０と外部装置との間の接続部構造を形成する場合に好適であり、導電性生地３０と外部装置との間の接続部構造における電極間距離を狭く形成することが可能となる。例えば、各配線間隔が３ｍｍの配線３２に対し、本発明の構造でパターン導電層３５を接続することで、各配線間隔を０．２～１ｍｍ程度の狭ピッチに変換することができ、フラットケーブル(ＦＦＣやＦＰＣ)に使用されるような一般的なコネクタ（汎用のフラットケーブル用コネクタ）に直接挿入することも可能となる。例えば、導電性生地３０上に形成された心拍、心電あるいは筋電などの生体情報を測定する電極と、その測定データを処理する外部装置との間の接続が容易になる。 Moreover, the conductive cloth 30 of the third embodiment according to the present invention has a pattern width and pitch of the pattern conductive layer 35 smaller than the pattern width and pitch of the wiring 32 formed of the conductive yarn 321 in the fiber structure 31. can do. The pattern of the wiring 32 has a minimum width defined by its knitting structure and yarn diameter, and it is difficult to reduce the pitch with the adjacent pattern due to problems such as a short circuit caused by fuzz of conductive yarns. On the other hand, since the pattern conductive layer 35 is formed by a printing technique, the line width and the line pitch can be reduced. In particular, the pattern conductive layer 35 is suitable for forming a connection portion structure between the conductive fabric 30 and the external device, and the inter-electrode distance in the connection portion structure between the conductive fabric 30 and the external device is reduced. It becomes possible to form narrowly. For example, by connecting the pattern conductive layer 35 with the structure of the present invention to the wiring 32 having a wiring interval of 3 mm, each wiring interval can be converted to a narrow pitch of about 0.2 to 1 mm. It can be directly inserted into a general connector (general-purpose flat cable connector) used in (FFC or FPC). For example, connection between electrodes for measuring biological information such as heartbeat, electrocardiogram, or myoelectricity formed on the conductive fabric 30 and an external device for processing the measurement data is facilitated.
　また、繊維構造体３１に含浸されている熱可塑性樹脂層３６は、パターン導電層３５と電気的に接続する配線３２を構成する導電性糸３２１の周りにおいて当該導電性糸３２１をコーティングする部材として機能しつつ、パターン導電層３５との強固な接着作用をも奏することとなる。したがって、パターン導電層３５と配線３２との接続部分における導電性糸３２１が酸化することや当該導電性糸３２１の金属皮膜が脱落してしまうことを効果的に防止し、その劣化を抑制することが可能となり、パターン導電層３５と配線３２との良好な導通状態を維持することが可能となる。 Further, the thermoplastic resin layer 36 impregnated in the fiber structure 31 is a member that coats the conductive yarn 321 around the conductive yarn 321 constituting the wiring 32 that is electrically connected to the pattern conductive layer 35. While functioning, a strong adhesive action with the pattern conductive layer 35 is also exhibited. Therefore, it is possible to effectively prevent the conductive thread 321 at the connection portion between the pattern conductive layer 35 and the wiring 32 from being oxidized and the metal film of the conductive thread 321 from dropping, and to suppress the deterioration. Therefore, it is possible to maintain a good conduction state between the pattern conductive layer 35 and the wiring 32.
　また、本発明に係る第３実施形態の繊維構造体３１は、編地構造を有することが好ましい。この構造を採用することにより、溶解した熱可塑性樹脂が、導電性生地３０の開口から内部に含浸されやすく、また、含浸された熱可塑性樹脂を良好に保持できる。また、溶解した熱可塑性樹脂が、パターン導電層３５が設けられる側とは反対側に大きく移動することを抑制することができる。 Further, the fiber structure 31 of the third embodiment according to the present invention preferably has a knitted fabric structure. By adopting this structure, the melted thermoplastic resin is easily impregnated into the inside from the opening of the conductive fabric 30, and the impregnated thermoplastic resin can be favorably retained. Moreover, it can suppress that the melt | dissolved thermoplastic resin moves largely to the opposite side to the side in which the pattern conductive layer 35 is provided.
　また、パターン導電層３５として、複数本が平行に配置された配線パターンを採用する場合に、例えば、図２９（ａ）に示すように、当該配線パターンを構成する配線３５１を有するパターン導電層３５を離型フィルム３７１上に形成する。このパターン導電層３５上に、熱可塑性樹脂層３６（例えば、ポリウレタンを含有する樹脂接着剤）をそれぞれの配線を覆うように（配線間は覆わないように）してプリント電極体３７を形成し、当該プリント電極体３７を繊維構造体３１上の所定位置に載置して加熱及び加圧することにより、導電性生地３０を構成する。このような導電性生地３０は、図２９（ｂ）に示すように、含浸される熱可塑性樹脂層３６が、各配線３５１の下方領域に存在し、配線３５１同士の間には存在しないように形成されるため、繊維構造体３１の通気性や柔軟性への影響を少なくできる。一方、図２９（ｃ）に示すように配線３５１間も熱可塑性樹脂層３６で覆うようにしてプリント電極体３７を形成して、導電性生地３０を構成した場合、配線パターンの耐久性や、高いパターン精度を確保することが可能となる。 When a wiring pattern in which a plurality of patterns are arranged in parallel is adopted as the pattern conductive layer 35, for example, as shown in FIG. 29A, the pattern conductive layer 35 having a wiring 351 constituting the wiring pattern. Is formed on the release film 371. A printed electrode body 37 is formed on the patterned conductive layer 35 by covering the wiring with a thermoplastic resin layer 36 (for example, a resin adhesive containing polyurethane) so as not to cover the wiring. The conductive cloth 30 is configured by placing the printed electrode body 37 at a predetermined position on the fiber structure 31 and heating and pressing it. In such a conductive fabric 30, as shown in FIG. 29 (b), the thermoplastic resin layer 36 to be impregnated exists in the lower region of each wiring 351 and does not exist between the wirings 351. Since it is formed, the influence on the air permeability and flexibility of the fiber structure 31 can be reduced. On the other hand, when the conductive cloth 30 is formed by forming the printed electrode body 37 so as to cover the wiring 351 with the thermoplastic resin layer 36 as shown in FIG. 29 (c), the durability of the wiring pattern, It is possible to ensure high pattern accuracy.
　以上、本発明に係る第３実施形態の導電性生地３０について説明したが、具体的構成は、上記実施形態に限定されない。例えば、端子部３４の接続端子（パターン導電層３５で形成される）において、コネクタとの抜挿の信頼性を高めるために、端子表面処理をしてもよい。端子表面処理としては、ニッケル等の端子メッキや、導電ペースト印刷などが例示できる。 The conductive fabric 30 according to the third embodiment of the present invention has been described above, but the specific configuration is not limited to the above embodiment. For example, in the connection terminal (formed with the pattern conductive layer 35) of the terminal portion 34, a terminal surface treatment may be performed in order to increase the reliability of insertion / removal with the connector. Examples of the terminal surface treatment include terminal plating of nickel or the like, conductive paste printing, and the like.
　また、上記第３実施形態においては、導電性糸３２１を用いて配線３２を製編して構成する例について説明したが、このような構成に特に限定されず、例えば、非導電性の地糸３３１を用いて製編した生地本体の所定領域に対して導電性樹脂を印刷することにより、所定形状の配線３２を生地本体上に形成してもよい。導電性樹脂を印刷する方法としては、スクリーン印刷、グラビア印刷、凸版印刷、凹版印刷、グラビアオフセット印刷、インクジェット印刷や、フォトリソグラフィ等の細線パターニングなど、周知の印刷法を用いることができる。また、導電性樹脂は、例えば、ポリエステル、ポリプロピレン、ポリエチレン、ポリエーテル、ポリウレタン、メタクリル樹脂、エポキシ樹脂、塩化ビニル、酢酸ビニル、塩化ビニル、酢酸ビニル共重合体等から選ばれた少なくとも一種よりなるバインダ（樹脂）中に、銀、塩化銀、チタン、ニッケル、白金、アルミニウム、ステンレス等から選ばれた少なくとも一種の微細粒子を含む導電性材料を混合して形成することができる。 Moreover, in the said 3rd Embodiment, although the example which knitted and comprised the wiring 32 using the conductive thread | yarn 321 was demonstrated, it is not specifically limited to such a structure, For example, a nonelectroconductive ground thread The wiring 32 having a predetermined shape may be formed on the fabric main body by printing a conductive resin on a predetermined region of the fabric main body knitted using 331. As a method for printing the conductive resin, a known printing method such as screen printing, gravure printing, letterpress printing, intaglio printing, gravure offset printing, ink jet printing, and fine line patterning such as photolithography can be used. The conductive resin is, for example, a binder made of at least one selected from polyester, polypropylene, polyethylene, polyether, polyurethane, methacrylic resin, epoxy resin, vinyl chloride, vinyl acetate, vinyl chloride, vinyl acetate copolymer, and the like. The (resin) can be formed by mixing a conductive material containing at least one kind of fine particles selected from silver, silver chloride, titanium, nickel, platinum, aluminum, stainless steel and the like.
　また、上記第３実施形態においては、端子部３４が、パターン導電層３５と、繊維構造体３１（生地本体）に含浸される熱可塑性樹脂層３６とを備えるように構成しているが、このような構成に特に限定されず、例えば、図３０の概略平面図に示すように、配線３２および端子部３４の両方について、上記端子部３４と同様な構造を有するように構成してもよい。つまり、端子部３４に加えて、生地本体が有する配線３２が、導電性材料及び樹脂を含むパターン導電層３５と、パターン導電層３５の少なくとも一方の面に接する熱可塑性樹脂層３６とを備え、熱可塑性樹脂層３６の少なくとも一部分が、生地本体に含浸されており、配線３２を形成するパターン導電層３５が、生地本体の露出表面に沿って配置されるように構成してもよい。このように配線３２についても上記端子部３４と同様な構造を採用する場合、プリント電極体３７として、例えば、離型フィルム３７１上に、印刷技術により、配線３２と端子部３４とに対応するパターン導電層３５を形成したものを用いればよい。なお、導電性生地３０が、配線３２を複数備える場合、全ての配線３２について、上記端子部３４と同様な構造を有するように構成してもよく、或いは、一部の配線３２についてのみ上記端子部３４と同様な構造を有するように構成してもよい。 Moreover, in the said 3rd Embodiment, although the terminal part 34 is comprised so that the pattern conductive layer 35 and the thermoplastic resin layer 36 with which the fiber structure 31 (fabric main body) is impregnated, this is comprised. For example, as shown in the schematic plan view of FIG. 30, both the wiring 32 and the terminal portion 34 may be configured to have the same structure as the terminal portion 34. That is, in addition to the terminal portion 34, the wiring 32 included in the fabric body includes a pattern conductive layer 35 containing a conductive material and a resin, and a thermoplastic resin layer 36 in contact with at least one surface of the pattern conductive layer 35. At least a part of the thermoplastic resin layer 36 may be impregnated in the fabric body, and the pattern conductive layer 35 forming the wiring 32 may be arranged along the exposed surface of the fabric body. As described above, when the wiring 32 has the same structure as that of the terminal portion 34, a pattern corresponding to the wiring 32 and the terminal portion 34 is formed on the release film 371 as the printed electrode body 37 by a printing technique. What formed the conductive layer 35 may be used. When the conductive fabric 30 includes a plurality of wirings 32, all the wirings 32 may be configured to have the same structure as the terminal part 34, or only a part of the wirings 32 may have the terminals. You may comprise so that it may have the same structure as the part 34. FIG.
　また、上記第３実施形態においては、生地本体に形成される配線３２の具体的構成は、特に限定されず、例えば、図３１に示すように、配線３２が互いに電気的に接続される第１配線部３２５と第２配線部３２６とを備えるように構成してもよい。この図３１における構成においては、繊維構造体３１（生地本体）上に所定間隔を空けて配置される機能部５０に、第２配線部３２６が電気的に接続されるように構成されており、端子部３４におけるパターン導電層３５に第１配線部３２５が電気的に接続されるように構成されている。なお、機能部５０としては、タッチセンサ等の各種センサ、発光素子、表示装置、スイッチ、発熱体、アクチュエータ、などの機能を有する電極や部材を例示することができる。 In the third embodiment, the specific configuration of the wiring 32 formed on the fabric body is not particularly limited. For example, as shown in FIG. 31, the first wiring 32 is electrically connected to each other. You may comprise so that the wiring part 325 and the 2nd wiring part 326 may be provided. In the configuration in FIG. 31, the second wiring portion 326 is configured to be electrically connected to the functional unit 50 arranged at a predetermined interval on the fiber structure 31 (fabric main body). The first wiring part 325 is configured to be electrically connected to the pattern conductive layer 35 in the terminal part 34. Examples of the functional unit 50 include electrodes and members having functions such as various sensors such as touch sensors, light emitting elements, display devices, switches, heating elements, actuators, and the like.
　ここで、第１配線部３２５及び第２配線部３２６は、それぞれ同一の材料によって形成してもよく、或いは、異なる材料によって形成してもよい。異なる材料によって形成する場合、例えば、導電性糸３２１を製編することにより第２配線部３２６を形成する一方、第１配線部３２５については、上記端子部３４と同様な構造を有するように形成してもよい。つまり、端子部３４に加えて、第１配線部３２５が、導電性材料及び樹脂を含むパターン導電層と、パターン導電層の少なくとも一方の面に接する熱可塑性樹脂層とを備え、熱可塑性樹脂層の少なくとも一部分が、生地本体に含浸されており、第１配線部３２５を形成するパターン導電層が、生地本体の露出表面に沿って配置されるように構成してもよい。このように第１配線部３２５についても上記端子部３４と同様な構造を採用する場合、プリント電極体３７として、例えば、離型フィルム３７１上に、印刷技術により、第１配線部３２５と端子部３４とに対応するパターン導電層３５を形成したものを用いればよい。なお、導電性生地３０が、第１配線部３２５を複数備える場合、全ての第１配線部３２５について、上記端子部３４と同様な構造を有するように構成してもよく、或いは、一部の第１配線部３２５についてのみ上記端子部３４と同様な構造を有するように構成してもよい。 Here, the first wiring part 325 and the second wiring part 326 may be formed of the same material, or may be formed of different materials. In the case of forming with different materials, for example, the second wiring part 326 is formed by knitting the conductive yarn 321, while the first wiring part 325 is formed to have the same structure as the terminal part 34. May be. That is, in addition to the terminal portion 34, the first wiring portion 325 includes a pattern conductive layer containing a conductive material and a resin, and a thermoplastic resin layer in contact with at least one surface of the pattern conductive layer. The fabric body may be impregnated at least in part, and the pattern conductive layer forming the first wiring part 325 may be arranged along the exposed surface of the fabric body. As described above, when the same structure as that of the terminal portion 34 is adopted for the first wiring portion 325 as well, the first wiring portion 325 and the terminal portion are formed on the release film 371 as the printed electrode body 37 by a printing technique, for example. What formed the pattern conductive layer 35 corresponding to 34 may be used.

　また、上記第３実施形態においては、熱可塑性樹脂層３６が、パターン導電層３５に対して繊維構造体３１側に設けられるように構成しているが、このような形態に特に限定されず、図３３や図３４の模式断面図に示すように、パターン導電層３５に対して、繊維構造体３１側とは反対側に熱可塑性樹脂層３６の一部が設けられるような構成を採用することもできる。このような構成の場合、外部装置との電気的な接続を考慮して、パターン導電層３５に対して繊維構造体３１側とは反対側の熱可塑性樹脂層３６の一部を部分的に除去して、パターン導電層３５が露出するように構成する。この図３３や図３４に示す構成の場合、パターン導電層３５の露出面が熱可塑性樹脂層３６によって被覆される形態となり、パターン導電層３５の表面保護を図ることができる。 Moreover, in the said 3rd Embodiment, although it has comprised so that the thermoplastic resin layer 36 may be provided in the fiber structure 31 side with respect to the pattern conductive layer 35, it is not specifically limited to such a form, As shown in the schematic cross-sectional views of FIGS. 33 and 34, a configuration in which a part of the thermoplastic resin layer 36 is provided on the side opposite to the fiber structure 31 side with respect to the pattern conductive layer 35 is adopted. You can also. In the case of such a configuration, a part of the thermoplastic resin layer 36 on the side opposite to the fiber structure 31 side with respect to the pattern conductive layer 35 is partially removed in consideration of electrical connection with an external device. Then, the pattern conductive layer 35 is configured to be exposed. 33 and 34, the exposed surface of the pattern conductive layer 35 is covered with the thermoplastic resin layer 36, and the surface of the pattern conductive layer 35 can be protected.
　また、上記第３実施形態において、図３５に示すように、配線３２が設けられる生地本体３が、部分的に突出する生地片３９を備え、当該生地片３９の先端部に端子部３４を配置するように構成し、図３６（ａ）（ｂ）の模式図に示すように、当該生地片３９を外部装置が備える外部デバイス回路のコネクタに直接的に挿入して接続するようにしてもよい。なお、図３６（ｂ）は、図３６（ａ）の断面に対応する模式図である。このような構成を採用する場合、端子部３４が備える熱可塑性樹脂層３６及びパターン導電層３５の少なくとも一部分が、該生地片３９に配置されるように構成する。なお、この生地片３９は、非導電性の地糸３３１から形成することができる。また、生地片３９の長さ（生地本体３からの突出長さ）は、適宜設定することができる。 In the third embodiment, as shown in FIG. 35, the fabric body 3 provided with the wiring 32 includes a fabric piece 39 that partially protrudes, and the terminal portion 34 is disposed at the tip of the fabric piece 39. As shown in the schematic diagrams of FIGS. 36 (a) and 36 (b), the fabric piece 39 may be directly inserted and connected to a connector of an external device circuit included in the external device. . Note that FIG. 36B is a schematic diagram corresponding to the cross section of FIG. When such a configuration is adopted, at least a part of the thermoplastic resin layer 36 and the pattern conductive layer 35 included in the terminal portion 34 is configured to be disposed on the fabric piece 39. The fabric piece 39 can be formed from a non-conductive ground yarn 331. In addition, the length of the fabric piece 39 (projection length from the fabric body 3) can be set as appropriate.
　また、図３５に示すように生地片３９を設ける場合には、図３６（ｂ）に示すように、当該生地片３９に補強部材３９１を設けるように構成してもよい。補強部材３９１は、生地片３９上においてパターン導電層３５が配置される面とは反対側の面であって、生地片３９の先端部分に配置されることが好ましい。なお、補強部材３９１をパターン導電層３５の露出面上に設けるようにしてもよい。このような場合、外部装置との電気的な接続を考慮して、補強部材３９１の一部を部分的に除去して、パターン導電層３５が露出するように構成する。また、補強部材３９１としては、例えば、樹脂フィルムや不織布、生地本体を構成する地糸３３１から形成した編地構造体等種々のものを採用することができる。また、樹脂によるコーティング層を補強部材３９１とすることもできる。このような補強部材３９１を設けることにより、生地片３９の先端側の剛性を高めることができるため、外部装置における電気信号取得用のコネクタ１００に生地片３９を挿入しやすくなるという効果を得ることができる。また、補強部材３９１の厚みを適宜設定して生地片の先端部分の厚み寸法を、コネクタ１００における挿入孔の厚み方向寸法と同程度に構成することにより、コネクタ１００に挿入された生地片３９の先端部が、挿入孔内で浮いてしまうことを防止して、しっかりと固定させることが可能となる。なお、図２３に示すように長尺状に導電性生地３０を構成し、その一方端を端子部３４とする場合においても、上記補強部材３９１を、端子部３４の先端部であって、パターン導電層３５が配置される面とは反対側の面に配置するようにしてもよい。 35, when the dough piece 39 is provided as shown in FIG. 35, a reinforcing member 391 may be provided on the dough piece 39 as shown in FIG. The reinforcing member 391 is preferably disposed on the tip of the fabric piece 39 on the opposite side of the surface on which the pattern conductive layer 35 is disposed on the fabric piece 39. The reinforcing member 391 may be provided on the exposed surface of the pattern conductive layer 35. In such a case, in consideration of electrical connection with an external device, a part of the reinforcing member 391 is partially removed so that the pattern conductive layer 35 is exposed. Moreover, as the reinforcing member 391, for example, various members such as a resin film, a nonwoven fabric, and a knitted fabric structure formed from the ground yarn 331 constituting the fabric main body can be adopted. Further, a coating layer made of resin can be used as the reinforcing member 391. By providing such a reinforcing member 391, the rigidity of the front end side of the fabric piece 39 can be increased, so that the effect of facilitating the insertion of the fabric piece 39 into the electrical signal acquisition connector 100 in the external device is obtained. Can do. Further, by setting the thickness of the reinforcing member 391 as appropriate and making the thickness dimension of the tip portion of the fabric piece approximately the same as the thickness direction dimension of the insertion hole in the connector 100, the fabric piece 39 inserted into the connector 100 It is possible to prevent the tip portion from floating in the insertion hole and fix it firmly. 23, when the conductive fabric 30 is formed in a long shape and one end thereof is used as the terminal portion 34, the reinforcing member 391 is the tip portion of the terminal portion 34, and the pattern You may make it arrange | position to the surface on the opposite side to the surface where the conductive layer 35 is arrange | positioned.
　また、生地片３９を設ける場合、図３７の模式断面図に示すように、生地片３９が、生地本体（繊維構造体３１）の表面から外方に突出するように形成してもよい。このような形態を採用することにより、例えば、繊維構造体３１を衣類(シャツ、パンツ、ズボン、靴下、手袋、帽子等の衣服、およびそれらの部材)として形成する場合であっても、そのデザイン性の自由度が高まり、また、外部装置との接続部構造である生地片３９が着用者にとって邪魔になってしまうことを効果的に抑制することが可能となる。なお、このような効果は、繊維構造体３１を衣類形体状(シャツ形やズボン形など)に形成する場合に限らず、図２３に示すように長尺状に導電性生地３０を構成し、例えば、心電図や筋電図等のデータ採取、或いは電気治療や電磁波治療などを対象者に対して行う場合に、対象者の腕や脚、胴部などに巻きつけて装着する場合であっても同様である。 Further, when the fabric piece 39 is provided, as shown in the schematic cross-sectional view of FIG. 37, the fabric piece 39 may be formed so as to protrude outward from the surface of the fabric body (fiber structure 31). By adopting such a form, for example, even when the fiber structure 31 is formed as clothing (clothes such as shirts, pants, trousers, socks, gloves, hats, and members thereof), the design The degree of freedom of the sex is increased, and it is possible to effectively suppress the cloth piece 39 that is a connection portion structure with an external device from becoming an obstacle to the wearer. Such an effect is not limited to the case where the fiber structure 31 is formed in a clothing shape (such as a shirt shape or a trouser shape), and the conductive fabric 30 is configured in a long shape as shown in FIG. For example, when collecting data such as an electrocardiogram or electromyogram, or performing electrical treatment or electromagnetic wave treatment on the subject, even if it is wrapped around the subject's arm, leg, trunk, etc. It is the same.
　また、上記第３実施形態において、繊維構造体３１における配線３２の少なくとも一部分が、図３８の模式断面図に示すように、繊維構造体３１においてパターン導電層３５が設けられる面とは反対側の面に露出するように構成してもよい。このような形態を採用することにより、例えば、心電図や筋電図等のデータ採取、或いは電気治療などを行う場合に、反対側の面に露出した配線３２が電極として機能する。導電性生地３０を対象者の腕や脚、胴部などに巻きつけて装着する場合に、対象者の身体の表面に配線３２を密着させつつ、装着された導電性生地３０の外表面側に外部装置との接続部構造であるパターン導電層３５が露出することになるため、使用上の簡便性を確保しつつ、確実に生体信号の取得等を行うことが可能となる。 Moreover, in the said 3rd Embodiment, as shown in the schematic cross section of FIG. 38, at least one part of the wiring 32 in the fiber structure 31 is on the opposite side to the surface in which the pattern conductive layer 35 is provided in the fiber structure 31. You may comprise so that it may be exposed to a surface. By adopting such a form, for example, when performing data collection such as electrocardiogram or electromyogram or electrotherapy, the wiring 32 exposed on the opposite surface functions as an electrode. When the conductive fabric 30 is wrapped around the subject's arm, leg, torso or the like, the wiring 32 is brought into close contact with the surface of the subject's body while the conductive fabric 30 is placed on the outer surface side of the worn conductive fabric 30. Since the pattern conductive layer 35 which is a connection portion structure with an external device is exposed, it is possible to reliably acquire a biological signal while ensuring ease of use.
　また、上述した本発明の導電性生地３０の製造方法は、プリント電極体３７における熱可塑性樹脂層３６及びパターン導電層３５を繊維構造体３１に転写することにより導電性生地３０を形成する方法であるが、このような転写技術を利用する他、以下のような方法によっても導電性生地３０を形成することができる。すなわち、図３９に示すように、フィルム状の熱可塑性樹脂層３６上に、印刷技術によりパターン導電層３５を形成することによりプリント電極体３７を形成し、繊維構造体３１における配線３２の少なくとも一部分上に、このプリント電極体３７の熱可塑性樹脂層３６側を向けて載置し（載置ステップＳ２）、その後、上記加熱・加圧ステップＳ３における工程を施すことにより、フィルム状の熱可塑性樹脂層３６を溶融させて繊維構造体３１に含浸させつつ、パターン導電層３５を繊維構造体３１の表面に設けるようにしてもよい。なお、フィルム状の熱可塑性樹脂層３６の厚みは、１０μｍ以上１００μｍ以下であることが好ましく、特に、２０μｍ以上８０μｍ以下であることがより好ましい。フィルム状の熱可塑性樹脂層３６の厚みが１０μｍ未満の場合、強度や取扱い性に問題がある。１００μｍより厚い場合、コストが高くなり、また導電性生地３０に十分な厚みがないと熱可塑性樹脂が裏面へにじみ出るおそれがある。 Moreover, the manufacturing method of the conductive cloth 30 of the present invention described above is a method of forming the conductive cloth 30 by transferring the thermoplastic resin layer 36 and the pattern conductive layer 35 in the printed electrode body 37 to the fiber structure 31. However, in addition to using such a transfer technique, the conductive cloth 30 can be formed by the following method. That is, as shown in FIG. 39, a printed electrode body 37 is formed by forming a patterned conductive layer 35 on a film-like thermoplastic resin layer 36 by a printing technique, and at least a part of the wiring 32 in the fiber structure 31 is formed. On top of this, the printed electrode body 37 is placed with the thermoplastic resin layer 36 side facing (placement step S2), and then the process in the heating / pressurizing step S3 is performed, thereby forming a film-like thermoplastic resin. The pattern conductive layer 35 may be provided on the surface of the fiber structure 31 while the layer 36 is melted and impregnated in the fiber structure 31. The thickness of the film-like thermoplastic resin layer 36 is preferably 10 μm or more and 100 μm or less, and more preferably 20 μm or more and 80 μm or less. When the thickness of the film-like thermoplastic resin layer 36 is less than 10 μm, there is a problem in strength and handleability. If it is thicker than 100 μm, the cost increases, and if the conductive fabric 30 does not have a sufficient thickness, the thermoplastic resin may ooze out to the back surface.
　上記フィルム状の熱可塑性樹脂層３６は、上述した熱可塑性樹脂層３６を構成する樹脂から形成することができるが、特にポリウレタン樹脂製のフィルムを熱可塑性樹脂層３６として採用することが好ましい。繊維構造体３１に含浸されたポリウレタン樹脂製のフィルムの厚み（量）が大きくなると、繊維構造体３１における含浸領域が僅かに固くなるため、パターン導電層３５が形成される導電性生地部分の強度を向上させることが可能となる。例えば、外部装置との接続部として用いる場合、端子間の幅精度を確保するために本構造を用いることが好ましい。 The film-like thermoplastic resin layer 36 can be formed from the resin constituting the thermoplastic resin layer 36 described above, and it is particularly preferable to employ a polyurethane resin film as the thermoplastic resin layer 36. When the thickness (amount) of the polyurethane resin film impregnated in the fiber structure 31 is increased, the impregnation region in the fiber structure 31 is slightly hardened, so that the strength of the conductive fabric portion on which the pattern conductive layer 35 is formed is increased. Can be improved. For example, when used as a connection portion with an external device, it is preferable to use this structure in order to ensure the width accuracy between terminals.
　また、上記第３実施形態において説明した導電性生地３０の製造方法においては、離型フィルム３７１上に、印刷技術によりパターン導電層３５を形成した後、当該パターン導電層３５上に、熱可塑性樹脂層３６を配設して構成されるプリント電極体３７を用い、このプリント電極体３７におけるパターン導電層３５及び熱可塑性樹脂層３６を繊維構造体３１に転写するようにしているが、このような手法の他、離型フィルム３７１上に印刷技術によりパターン導電層３５を形成してプリント電極体３７を構成し、例えば、シート状、液状、粉状、或いは、粒状の熱可塑性樹脂を、繊維構造体３１における配線３２の少なくとも一部分上に塗布又は配置した上で、当該プリント電極体３７を載置し、加熱・加圧ステップＳ３によるヒートプレスを行うようにして、シート状、液状、粉状、或いは、粒状の熱可塑性樹脂を溶融させて繊維構造体３１に含浸させつつ、パターン導電層３５を繊維構造体３１の表面に設けるようにしてもよい。なお、ヒートプレスを、繊維構造体３１の形状を保ちつつ、繊維構造体３１の露出表面にパターン導電層３５が密着する加熱・加圧条件とすることで、生地の風合いを損なわない。 In the method for manufacturing the conductive fabric 30 described in the third embodiment, after the pattern conductive layer 35 is formed on the release film 371 by a printing technique, the thermoplastic resin is formed on the pattern conductive layer 35. A printed electrode body 37 configured by arranging the layer 36 is used, and the pattern conductive layer 35 and the thermoplastic resin layer 36 in the printed electrode body 37 are transferred to the fiber structure 31. In addition to the method, the pattern conductive layer 35 is formed on the release film 371 by a printing technique to form the printed electrode body 37. For example, a sheet-like, liquid, powdery, or granular thermoplastic resin is used as a fiber structure. After applying or disposing on at least a part of the wiring 32 in the body 31, the printed electrode body 37 is placed, and the heating / pressurizing step S3 is performed. The pattern conductive layer 35 is provided on the surface of the fiber structure 31 while the sheet structure, liquid, powder, or granular thermoplastic resin is melted and impregnated in the fiber structure 31. May be. Note that the texture of the fabric is not impaired by setting the heat press to heating / pressurizing conditions in which the pattern conductive layer 35 is in close contact with the exposed surface of the fiber structure 31 while maintaining the shape of the fiber structure 31.
　また、上記第３実施形態において、地糸３３１又は導電性糸３２１に、熱融着糸および熱合着糸の少なくとも一方を混合して、繊維構造体３１（生地本体）にほつれ止め処理を施してもよい。ほつれ止め処理は、繊維構造体３１の形成に用いた地糸３３１や導電性糸３２１が編織等組織の中で交差している部分を固定させる処理であって、このほつれ止め処理を施すことで、地糸３３１や導電性糸３２１の糸端が浮遊状態となるのを阻止している。ほつれ止め処理の実施方法は、繊維構造体３１の形成に用いる地糸３３１や導電性糸３２１に対し、熱融着糸および熱合着糸の少なくとも一方を混用させ、そのうえで繊維構造体３１を製編し、製編後に熱セットを行うという手順とする。導電性生地３０を所定形状に切断する場合に、少なくともその形状の外縁部に対しこのようなほつれ止め処理を施すことで、導電性生地３０の切断端縁がほつれることがなくなる。特に、端子部３４（生地片３９）にほつれ止め処理を行うことで、外部デバイス回路のコネクタと確実に接続することができる。 In the third embodiment, at least one of a heat fusion yarn and a heat fusion yarn is mixed with the ground yarn 331 or the conductive yarn 321, and the fiber structure 31 (fabric main body) is subjected to a fraying prevention treatment. May be. The fraying prevention process is a process of fixing a portion where the ground yarn 331 and the conductive yarn 321 used for forming the fiber structure 31 intersect in a structure such as a knitted fabric, and this fraying prevention process is performed. The yarn ends of the ground yarn 331 and the conductive yarn 321 are prevented from floating. In the fraying prevention treatment method, at least one of a thermal fusing yarn and a thermal fusing yarn is mixed with the ground yarn 331 and the conductive yarn 321 used for forming the fibrous structure 31, and then the fibrous structure 31 is manufactured. Knitting and heat setting after knitting. When the conductive fabric 30 is cut into a predetermined shape, the cut edge of the conductive fabric 30 is not frayed by applying such a fraying prevention process to at least the outer edge portion of the shape. In particular, the fraying prevention process is performed on the terminal portion 34 (fabric piece 39), so that it can be reliably connected to the connector of the external device circuit.
　ここで、熱融着糸と熱合着糸との差異は、半溶融状態からの冷却により生じる結合力の強弱によって区別すればよく、結合力が強い（熱融着）ものは熱融着糸とし、これよりも結合力が弱い（合着）ものは熱合着糸とする。この区別は明確とは言えず曖昧模糊とした部分を含むが、要は、本発明では熱セットによって地糸３３１や導電性糸３２１の交差部を結合できるものであればよい。従って、伸縮性（弾性）に優れ、加熱によって熱融着し、かつ、熱融着部位においては伸縮性（弾性）が失われることなく、高度の伸縮性（弾性）が保有されるものを用いることができる。 Here, the difference between the heat-bonded yarn and the heat-bonded yarn may be distinguished by the strength of the bonding force generated by cooling from the semi-molten state. The one having a weaker binding force (bonding) than this is a heat-bonding yarn. Although this distinction is not clear and includes an ambiguous portion, in the present invention, what is necessary is that the intersection of the ground yarn 331 and the conductive yarn 321 can be combined by heat setting. Accordingly, a material that has excellent stretchability (elasticity), is heat-sealed by heating, and retains high stretchability (elasticity) without losing stretchability (elasticity) at the heat-sealed portion. be able to.
