Description

本発明は、通電可能な第一糸材（芯糸に巻装された導電糸を備えた糸材）と、第一糸材よりも収縮しやすい第二糸材の双方を構成糸とする布材に関する。   The present invention provides a fabric comprising both a first thread material that can be energized (a thread material having a conductive thread wound around a core thread) and a second thread material that is more easily contracted than the first thread material. Regarding materials.

この種の第一糸材として、特許文献１に開示の糸材が公知である。この第一糸材は、パイル繊維糸条（芯糸）と、複数のカバリング糸（導電糸、結束糸）を有する。芯糸は、加撚された紡績糸又はマルチフィラメントであり、特に素材の限定はない。また導電糸は、金属繊維フィラメント（単糸）であり、結束糸は、ナイロンやポリエステル繊維のモノフィラメント糸である。公知技術では、導電糸を芯糸にスパイラル状に巻装したのち、結束糸を、導電糸の撚り方向とは逆にして芯糸にスパイラル状に巻装する（ダブルカバリングする）。このように導電糸と結束糸を交叉状に配置することで、結束糸にて導電糸を芯糸側に押え込むことができる。   As this type of first thread material, a thread material disclosed in Patent Document 1 is known. This first yarn material has pile fiber yarn (core yarn) and a plurality of covering yarns (conductive yarn, binding yarn). The core yarn is a twisted spun yarn or multifilament, and the material is not particularly limited. The conductive yarn is a metal fiber filament (single yarn), and the binding yarn is a monofilament yarn of nylon or polyester fiber. In the known technique, the conductive yarn is wound around the core yarn in a spiral shape, and then the binding yarn is wound around the core yarn in a spiral shape (double covering) opposite to the twisting direction of the conductive yarn. Thus, by arranging the conductive yarn and the binding yarn in a cross shape, the conductive yarn can be pressed to the core yarn side by the binding yarn.

そして上述の第一糸材は、車両用シートの表皮材（布材の一例）の構成糸に好適に使用できる。ここで一般的な表皮材は、複数の糸材を構成糸として有する面状部材（織物や編物等）である。そこで表皮材の作成に際して、例えば天然繊維又は化学繊維製の第二糸材（第一糸材よりも収縮しやすい糸材）をベースの構成糸として、第一糸材を構成糸の一部に使用する。そして第一糸材と第二糸材にて表皮材（織物）を製織したのち、染色仕上げ工程などの各種加工を施して表皮材を作成する。こうして作成された表皮材は、通電可能な第一糸材を有することから、静電容量式センサの電極やヒータとして使用できる（利便性に優れるシート構成となる）。   And the above-mentioned 1st thread material can be conveniently used for the constituent thread of the skin material (an example of cloth material) of a vehicular seat. Here, a general skin material is a planar member (woven fabric or knitted fabric) having a plurality of yarn materials as constituent yarns. Therefore, when creating the skin material, for example, a second yarn material made of natural fiber or chemical fiber (a yarn material that is more easily contracted than the first yarn material) is used as a base component yarn, and the first yarn material is used as a part of the component yarn. use. After weaving the skin material (woven fabric) with the first thread material and the second thread material, various processes such as a dyeing finishing process are performed to create the skin material. Since the skin material produced in this way has the 1st thread material which can supply with electricity, it can be used as an electrode or heater of an electrostatic capacitance type sensor (it becomes the sheet composition excellent in convenience).

特開平１０−８３４０号公報Japanese Patent Laid-Open No. 10-8340

ところで上述の車両用シートの表皮材では、着座性向上の観点などから、適度な伸縮性を有することが望ましい。このため上述のように、表皮材（織物）を製織したのち、染色仕上げ加工等で熱収縮させて適度な伸縮性を付与する。このとき導電糸を芯糸に巻装した場合（シングルカバリングの場合）では、例えば染色仕上げ工程（加熱処理又は揉み処理）中に、導電糸が、芯糸から分離して引出されるなどして表皮材から部分的に飛び出すことがあった。また公知技術（ダブルカバリング）の場合でも、染色仕上げ工程中に、結束糸の拘束が緩むなどして、導電糸が、拘束糸とともに芯糸から浮きあがることにより表皮材から飛び出すことがあった。そして表皮材から導電糸が飛び出すことにより、表皮材の性能が悪化する（例えば応力集中による導電糸の断線、異物感、温度ムラが生じる）ことがあった。例えば導電糸が、部分的な飛び出しにて（短くなることで）、カバリング状態から直線状に延びた状態となる。このため導電糸と平行方向に布材が引っ張られた場合、導電糸が、布材の伸長に追従できず断線するおそれがあった。本発明は上述の点に鑑みて創案されたものであり、本発明が解決しようとする課題は、通電可能な第一糸材の性能をより向上させることにある。   By the way, it is desirable that the above-described skin material of the vehicle seat has an appropriate stretchability from the viewpoint of improving the seating property. For this reason, as described above, after weaving the skin material (woven fabric), it is heat-shrinked by dyeing finishing or the like to impart appropriate stretchability. In this case, when the conductive yarn is wound around the core yarn (in the case of single covering), for example, during the dyeing finishing process (heat treatment or stagnation treatment), the conductive yarn is pulled out from the core yarn. There was a case where a part of the skin material jumped out. Further, even in the case of the known technique (double covering), the binding yarn may be loosened during the dyeing and finishing process, and the conductive yarn may float from the core yarn together with the binding yarn, and may jump out of the skin material. Further, when the conductive yarn jumps out of the skin material, the performance of the skin material may be deteriorated (for example, disconnection of the conductive yarn due to stress concentration, foreign object feeling, temperature unevenness may occur). For example, when the conductive yarn partially protrudes (becomes shorter), the conductive yarn extends from the covering state to a straight line. For this reason, when the cloth material is pulled in a direction parallel to the conductive yarn, the conductive thread may not follow the elongation of the cloth material and may be disconnected. The present invention has been made in view of the above points, and a problem to be solved by the present invention is to further improve the performance of the first thread material that can be energized.

上記課題を解決するための手段として、第１発明の布材は、通電可能な第一糸材と、第一糸材よりも収縮しやすい第二糸材の双方を構成糸として備える。そして第二糸材との収縮差により第一糸材が蛇行状に配置する構成である。本発明では、第一糸材が芯糸と導電糸を有するのであるが、この種の構成では、第一糸材の性能をより向上できる（例えば芯糸に対する導電糸の分離を極力抑えられる）ことが望ましい。そこで本発明では、第一糸材が、芯糸と、芯糸に対してスパイラル状に巻装される導電糸と、芯糸に対してスパイラル状に巻装されて導電糸を覆い隠すように配置される被覆糸とを有するとともに、下記（１）と（２）のいずれかの構成を備える。（１）被覆糸が、芯糸及び導電糸よりも融点が低い部位を有する。（２）芯糸が、被覆糸及び導電糸よりも融点が低い部位を有する。本発明では、被覆糸又は芯糸（全部又は一部）を溶融固化させることにより、芯糸に対する導電糸の分離を極力抑えることができる。   As means for solving the above-mentioned problems, the cloth material of the first invention includes both a first thread material that can be energized and a second thread material that is more easily contracted than the first thread material as constituent yarns. And it is the structure which a 1st thread material arrange | positions in a meandering manner by the shrinkage | contraction difference with a 2nd thread material. In the present invention, the first yarn material has the core yarn and the conductive yarn. With this type of configuration, the performance of the first yarn material can be further improved (for example, the separation of the conductive yarn from the core yarn can be suppressed as much as possible). It is desirable. Therefore, in the present invention, the first yarn material is formed such that the core yarn, the conductive yarn wound spirally around the core yarn, and the spiral winding around the core yarn covers the conductive yarn. It has a covering yarn to be arranged, and has one of the following configurations (1) and (2). (1) The covered yarn has a portion having a lower melting point than the core yarn and the conductive yarn. (2) The core yarn has a portion having a lower melting point than the coated yarn and the conductive yarn. In the present invention, separation of the conductive yarn from the core yarn can be suppressed as much as possible by melting and solidifying the coated yarn or the core yarn (all or a part).

第２発明の布材は、第１発明の布材であって、第一糸材が、芯糸よりも嵩高な滑り防止糸を有するとともに、滑り防止糸が、芯糸にスパイラル状に巻装されて、第二糸材に接触可能に配置する。本発明では、滑り防止糸にて、第二糸材に対する第一糸材のズレを極力阻止できる。   The cloth material of the second invention is the cloth material of the first invention, wherein the first thread material has an anti-slip yarn bulkier than the core yarn, and the anti-slip yarn is wound around the core yarn in a spiral shape. And arranged so as to be in contact with the second thread material. In the present invention, the slippage of the first yarn material relative to the second yarn material can be prevented as much as possible by the anti-slip yarn.

本発明に係る第１発明によれば、通電可能な第一糸材の性能をより向上させることができる。また第２発明によれば、通電可能な第一糸材の性能を更に向上させることができる。   According to the 1st invention concerning the present invention, the performance of the 1st thread material which can be energized can be improved more. According to the second invention, the performance of the first yarn material that can be energized can be further improved.

以下、本発明を実施するための形態を、図１〜図５を参照して説明する。各図には、適宜、車両用シート前方に符号Ｆ、車両用シート後方に符号Ｂ、車両用シート上方に符号ＵＰ、車両用シート下方に符号ＤＷを付す。図１の車両用シート２は、シートクッション４と、シートバック６と、ヘッドレスト８を有する。これらシート構成部材は、各々、シート外形をなして乗員を弾性的に支持するクッション材（４Ｐ，６Ｐ，８Ｐ）と、クッション材を被覆する表皮材（４Ｓ，６Ｓ，８Ｓ）を有する。   Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. In each of the drawings, a reference symbol F is attached to the front of the vehicle seat, a reference symbol B is attached to the rear of the vehicle seat, a reference symbol UP is provided above the vehicle seat, and a reference symbol DW is provided below the vehicle seat. The vehicle seat 2 in FIG. 1 has a seat cushion 4, a seat back 6, and a headrest 8. Each of these seat constituent members includes a cushion material (4P, 6P, 8P) that elastically supports an occupant by forming a seat outer shape, and a skin material (4S, 6S, 8S) that covers the cushion material.

本実施形態では、シートクッション４の表皮材４Ｓの一部が通電可能とされて、静電容量式センサの電極又はヒータとして機能する（図１及び図２を参照）。すなわち表皮材４Ｓの一部（構成糸）に、通電可能な第一糸材１１と、第一糸材１１よりも収縮しやすい第二糸材１２が使用される（各糸材の詳細は後述）。そして第一糸材１１と第二糸材１２の収縮性の違いを利用しつつ、両糸材の間に長さの違い（糸長差）を生じさせて、第一糸材１１を面方向に蛇行状に配置する。そして本実施形態では、後述のように第一糸材１１が、芯糸２０と、導電糸２２（カバリング糸）を有する。この種の構成では、第一糸材１１の性能をより向上できる（例えば芯糸に対する導電糸の分離を極力抑えられる）ことが望ましい。そこで本実施形態では、後述の構成にて、第一糸材１１の性能をより向上させることとした。以下、各構成について詳述する。   In the present embodiment, a part of the skin material 4S of the seat cushion 4 can be energized, and functions as an electrode or a heater of the capacitive sensor (see FIGS. 1 and 2). That is, the first thread material 11 that can be energized and the second thread material 12 that is more easily contracted than the first thread material 11 are used for a part (constituent thread) of the skin material 4S (details of each thread material will be described later). ). Then, while utilizing the difference in contractibility between the first thread material 11 and the second thread material 12, a difference in length (yarn length difference) is generated between the two thread materials, and the first thread material 11 is moved in the surface direction. Arranged in a serpentine shape. In the present embodiment, the first yarn material 11 includes the core yarn 20 and the conductive yarn 22 (covering yarn) as described later. In this type of configuration, it is desirable that the performance of the first yarn material 11 can be further improved (for example, separation of the conductive yarn from the core yarn can be suppressed as much as possible). Therefore, in the present embodiment, the performance of the first thread material 11 is further improved with the configuration described later. Hereinafter, each configuration will be described in detail.

［表皮材（布材）］
表皮材４Ｓは、袋状の面状部材であり、複数の表皮ピース（第一表皮ピース４０ｆ，第二表皮ピース４０ｓなど）を縫合して形成できる（図１及び図２を参照）。そして第一表皮ピース４０ｆは、シート中央（座面）形状に倣った略矩形の面状部材である。本実施形態では、第一表皮ピース４０ｆが布材を用いて形成されており、第一糸材１１と、第二糸材１２と、接続部材３０を有する（各糸材及び部材の構成は後述）。そして後述するように、第一表皮ピース４０ｆを、接続部材３０を介して電源９に電気的に接続することにより、表皮材４Ｓを、静電容量式センサの電極やヒータとして機能させることができる。また第二表皮ピース４０ｓは、シート側部形状に倣った形状の面状部材であり、布帛（織物，編物，不織布）、皮革（天然皮革，合成皮革）又はこれらの複合材にて形成できる。なお各表皮ピースの裏面側（クッション材を臨む側）には、パッド材１４（典型的に発泡樹脂製の面材）と、裏基布１６（例えば不織布）を積層状に配置できる。 [Skin material (cloth material)]
The skin material 4S is a bag-like planar member, and can be formed by stitching a plurality of skin pieces (first skin piece 40f, second skin piece 40s, etc.) (see FIGS. 1 and 2). The first skin piece 40f is a substantially rectangular planar member that follows the center (seat surface) shape of the seat. In the present embodiment, the first skin piece 40f is formed using a cloth material, and includes a first thread material 11, a second thread material 12, and a connection member 30 (configurations of each thread material and members will be described later). ). Then, as will be described later, by electrically connecting the first skin piece 40f to the power source 9 via the connecting member 30, the skin material 4S can be made to function as an electrode or a heater of a capacitive sensor. . The second skin piece 40s is a planar member having a shape that follows the shape of the side of the seat, and can be formed of fabric (woven fabric, knitted fabric, nonwoven fabric), leather (natural leather, synthetic leather), or a composite material thereof. Note that a pad material 14 (typically a foam resin surface material) and a back base fabric 16 (for example, a nonwoven fabric) can be arranged in a laminated manner on the back surface side (the side facing the cushion material) of each skin piece.

［第一糸材］
第一糸材１１は、通電性を有するカバリング構造の糸材であり、芯糸２０と、複数種類のカバリング糸（導電糸２２（樹脂皮膜），被覆糸２４，滑り防止糸２６）を有する（図２及び図３を参照）。このように第一糸材１１をカバリング構造とすることで、第一糸材１１に力がかかったとき、カバリング糸としての導電糸２２に力がかかる前に芯糸２０に負担させることができる（導電糸への負荷を軽減できる）。そして本実施形態では、後述するように導電糸２２を覆い隠す被覆糸２４（全部又は一部）を溶融固化させることにより、芯糸２０に対する導電糸２２の分離を極力抑えることとした。 [First thread material]
The first thread material 11 is an electrically conductive covering material having a covering structure, and includes a core thread 20 and a plurality of types of covering threads (conductive thread 22 (resin film), covering thread 24, anti-slip thread 26) ( (See FIGS. 2 and 3). Thus, by making the 1st thread material 11 into a covering structure, when force is applied to the 1st thread material 11, it can be made to bear to the core thread | yarn 20 before force is applied to the conductive thread 22 as covering thread. (The load on the conductive yarn can be reduced). In this embodiment, the separation of the conductive yarn 22 from the core yarn 20 is suppressed as much as possible by melting and solidifying the covering yarn 24 (all or a part) covering the conductive yarn 22 as described later.

（芯糸）
芯糸２０は、紡績糸、フィラメント糸、延伸糸及び伸縮加工糸（仮撚加工糸や座屈糸）等の糸材である（図３を参照）。芯糸２０として、複数の糸材を引き揃えるなどして使用することができ、また単数の糸材を使用することもできる。芯糸２０（材質）は特に限定しないが、植物系及び動物系の天然繊維、熱可塑性樹脂又は熱硬化性樹脂からなる化学繊維及びこれらの混繊糸を例示できる。天然繊維では、綿、麻又は羊毛が風合いに優れるため、第一表皮ピース４０ｆ（表皮材４Ｓ）の構成糸として用いることが好ましい。また化学繊維では、ポリエステル繊維（例えばポリエチレンテレフタレートのフィラメント）やナイロン繊維は耐久性と風合いと強度に優れるため、第一表皮ピース４０ｆ（表皮材４Ｓ）の構成糸として用いることが好ましい。 (Core yarn)
The core yarn 20 is a thread material such as a spun yarn, a filament yarn, a drawn yarn, and an elastic yarn (false twisted yarn or buckling yarn) (see FIG. 3). The core yarn 20 can be used by arranging a plurality of yarn materials, or a single yarn material can be used. The core yarn 20 (material) is not particularly limited, and examples thereof include plant-based and animal-based natural fibers, chemical fibers made of a thermoplastic resin or a thermosetting resin, and mixed fibers thereof. In natural fibers, cotton, hemp or wool is excellent in texture, so that it is preferably used as a constituent yarn of the first skin piece 40f (skin material 4S). As chemical fibers, polyester fibers (for example, polyethylene terephthalate filaments) and nylon fibers are excellent in durability, texture, and strength, and are therefore preferably used as constituent yarns of the first skin piece 40f (skin material 4S).

（導電糸）
導電糸２２は、通電可能な導電性の線材であり、典型的に比抵抗が１０^０〜１０^−１２Ω・ｃｍ（好ましくは１０^-３〜１０^−７Ω・ｃｍ）である（図３（ａ）〜（ｃ）を参照）。ここで「比抵抗（体積抵抗率とも呼ぶ）」とは、どのような材料が電気を通しにくいかを比較するために用いられる物性値であり、例えば「ＪＩＳ Ｃ２５２５ ７．２．Ｃ 体積抵抗率」に準拠して測定することができる。この種の導電糸２２として、金属（銅やアルミニウム等）や合金などの糸材、メッキ線材、炭素繊維のフィラメントを例示できる。メッキ線材は、非導電性又は導電性の線材（芯材）と、金属又は合金のメッキ層を有する。また炭素繊維とは、ポリアクリロニトリル系炭素繊維（ＰＡＮ系炭素繊維）やピッチ系炭素繊維である。なかでも焼成温度１０００℃以上の炭素繊維（炭素化繊維、黒鉛化繊維、黒鉛繊維）のフィラメントは良好な電気伝導性を有するため、本実施形態の導電糸２２として好適に使用できる。なお導電糸２２は、単数の導電糸にて形成することができ、また複数の導電糸を撚り合せて形成することもできる。特に単数の導電糸２２の径が太い場合（例えば４０μｍを超える太さの場合）や、複数の素線（導電糸）を撚り合せて用いる場合、導電糸２２の曲げ剛性が高くなり芯糸２０から分離しやすくなるため、本実施形態の構成（後述の被覆糸など）が有効である。 (Conductive yarn)
The conductive yarn 22 is a conductive wire that can be energized, and typically has a specific resistance of 10 ⁰ to 10 ⁻¹² Ω · cm (preferably 10 ⁻³ to 10 ⁻⁷ Ω · cm) (FIG. 3 ( a) to (c)). Here, “specific resistance (also referred to as volume resistivity)” is a physical property value used for comparing what kind of material is difficult to conduct electricity. For example, “JIS C2525 7.2.C volume resistivity”. "Can be measured in accordance with. Examples of this type of conductive yarn 22 include yarn materials such as metals (copper, aluminum, etc.) and alloys, plated wire materials, and carbon fiber filaments. The plated wire has a non-conductive or conductive wire (core material) and a plated layer of metal or alloy. Carbon fibers are polyacrylonitrile-based carbon fibers (PAN-based carbon fibers) and pitch-based carbon fibers. Among them, filaments of carbon fibers (carbonized fibers, graphitized fibers, graphite fibers) having a firing temperature of 1000 ° C. or higher have good electrical conductivity and can be suitably used as the conductive yarns 22 of the present embodiment. The conductive yarn 22 can be formed of a single conductive yarn, or can be formed by twisting a plurality of conductive yarns. In particular, when the diameter of the single conductive yarn 22 is large (for example, when the thickness exceeds 40 μm), or when a plurality of strands (conductive yarn) are twisted and used, the bending rigidity of the conductive yarn 22 increases and the core yarn 20 Therefore, the configuration of the present embodiment (such as a coated yarn described later) is effective.

（樹脂皮膜）
樹脂皮膜（図示省略）は、導電糸２２よりも耐水性（水によって変質しにくい性質）に優れる樹脂層であり、導電糸２２表面（略全面）に設けることができる。このように樹脂皮膜にて導電糸２２を覆うことで、導電糸２２の錆つきや加水分解を抑制することにより、第一糸材１１の耐久性を向上させることができる。この種の樹脂として、ポリアミド樹脂、塩化ビニル樹脂、フッ素樹脂、アクリル樹脂及びシリコン樹脂を例示できる。なお樹脂皮膜の厚み寸法は特に限定しないが、典型的には１０〜１００μｍである。 (Resin film)
The resin film (not shown) is a resin layer that is more excellent in water resistance (proper property of being hardly changed by water) than the conductive yarn 22, and can be provided on the surface (substantially the entire surface) of the conductive yarn 22. By covering the conductive yarn 22 with the resin film in this manner, the durability of the first yarn material 11 can be improved by suppressing rusting and hydrolysis of the conductive yarn 22. Examples of this type of resin include polyamide resin, vinyl chloride resin, fluororesin, acrylic resin, and silicon resin. The thickness dimension of the resin film is not particularly limited, but is typically 10 to 100 μm.

（被覆糸）
被覆糸２４は、芯糸２０に対してスパイラル状に巻装される糸材であり、導電糸２２を覆い隠すように配置される（図３及び図４を参照）。本実施形態では、被覆糸２４の一部又は全部に、融点の比較的低い部位（融着部位）が形成されており、後述の各種熱処理工程において溶融可能である。融着部位は、典型的に被覆糸２４の軸線方向に沿って連続的又は断続的に形成できる。ここで融着部位は、芯糸２０及び導電糸２２よりも融点が低い部位であり、その他の布材の構成要素（後述の滑り防止糸２６及び第二糸材１２）よりも融点が低いことが望ましい。そして被覆糸２４（融着部位）が溶融固化しつつ導電糸２２を覆う（接着作用を奏する）ことにより、芯糸２０に対する導電糸２２の分離を極力抑えることができる。融着部位の材質は特に限定しないが、ポリアミド系樹脂、ポリエステル系樹脂、ポリエチレン系樹脂、オレフィン系樹脂を例示でき、融点が１００℃以上の樹脂であることが好ましい。そして融着部位の融点は、他の構成要素を考慮して適宜設定可能であり、他の構成要素（特に芯糸２０）よりも２０℃以下であることが望ましい。例えばポリエチレンテレフタレートを他の構成要素（芯糸２０等）の材質として使用する場合、融着部位の融点を１００℃〜２４０℃の範囲に設定できる。 (Coated yarn)
The covering yarn 24 is a yarn material wound spirally around the core yarn 20, and is arranged so as to cover the conductive yarn 22 (see FIGS. 3 and 4). In this embodiment, a part (or all part) of the coated yarn 24 is formed with a part having a relatively low melting point (fusing part) and can be melted in various heat treatment steps described later. The fusion site can typically be formed continuously or intermittently along the axial direction of the coated yarn 24. Here, the fusion part is a part having a melting point lower than that of the core yarn 20 and the conductive yarn 22 and has a melting point lower than those of other components of the fabric material (the anti-slip yarn 26 and the second yarn material 12 described later). Is desirable. Then, the covering yarn 24 (fused part) covers the conductive yarn 22 while melting and solidifying (having an adhesive action), whereby separation of the conductive yarn 22 from the core yarn 20 can be suppressed as much as possible. The material of the fused part is not particularly limited, and examples thereof include polyamide resins, polyester resins, polyethylene resins, and olefin resins, and a resin having a melting point of 100 ° C. or higher is preferable. The melting point of the fusion part can be appropriately set in consideration of other components, and is preferably 20 ° C. or lower than other components (particularly the core yarn 20). For example, when polyethylene terephthalate is used as a material for other constituent elements (core yarn 20 or the like), the melting point of the fused part can be set in the range of 100 ° C to 240 ° C.

ここで被覆糸２４の一部を融着部位とする場合、被覆糸２４の他部を、融着部位よりも高融点の材質にて形成するとともに、被覆糸２４の軸線方向に沿って連続的に配置することが望ましい。このように被覆糸２４の他部を高融点とする（融着部位とともに溶融しない構成とする）ことで、溶融部位が溶融にて不定形状化しても、被覆糸２４の糸材としての機能を維持できる。   Here, when a part of the covering yarn 24 is used as a fusion part, the other part of the covering yarn 24 is formed of a material having a melting point higher than that of the fusion part, and continuously along the axial direction of the covering yarn 24. It is desirable to arrange in. Thus, by setting the other part of the coated yarn 24 to a high melting point (a configuration that does not melt together with the fused portion), the function of the coated yarn 24 as a yarn material can be achieved even if the melted portion becomes indefinite shape by melting. Can be maintained.

被覆糸２４として、加熱により溶融可能な融着糸を単独で使用でき、また融着糸と他の糸材（後述の滑り防止糸２６等）を混在させて使用できる。ここで融着糸の種類は特に限定しないが、混繊型、芯鞘型、全溶型又は複合型の融着糸を例示できる。例えば芯鞘型の融着糸（被覆糸２４ａ）とは、高融点の芯部２５ａと、低融点の鞘部２５ｂ（融着部位）で構成される糸材である（図４（ａ）を参照）。そして鞘部２５ｂ（融着部位）の融点が、芯部２５ａの融点よりも２０℃以下であることが望ましい。また混繊型の融着糸（被覆糸２４ｂ）とは、高融点の繊維２５ｃと、低融点の繊維２５ｄ（融着部位）が混在する合成繊維の糸材である（図４（ｂ）では、便宜上、一部の繊維に符号を付し、同種の繊維については同一のハッチングを施して符号を省略する）。そして低融点の繊維２５ｄ（融着部位）の融点が、高融点の繊維２５ｃの融点よりも２０℃以下であることが望ましい。ここで被覆糸２４として、融着糸と他の糸材を混在させて使用することで、第一糸材１１全面が融着糸（溶融固化後）に覆われることを阻止することもできる。こうすることで第一糸材の柔軟性を好適に保持するなどして、好適に蛇行させることができる。   As the covering yarn 24, a fusing yarn that can be melted by heating can be used alone, or a fusing yarn and another yarn material (such as an anti-slip yarn 26 described later) can be mixed and used. Here, the type of the fused yarn is not particularly limited, and examples thereof include a mixed fiber type, a core-sheath type, a total melt type, and a composite type fused yarn. For example, the core-sheath-type fusion yarn (covered yarn 24a) is a yarn material composed of a core portion 25a having a high melting point and a sheath portion 25b (fusion portion) having a low melting point (see FIG. 4A). reference). And it is desirable for melting | fusing point of the sheath part 25b (fusion | fusion site | part) to be 20 degrees C or less rather than melting | fusing point of the core part 25a. The mixed fiber type fused yarn (covered yarn 24b) is a synthetic fiber yarn material in which high melting point fibers 25c and low melting point fibers 25d (fusion sites) are mixed (in FIG. 4B). For convenience, some fibers are given reference numerals, and the same type of fibers are given the same hatching, and the reference numerals are omitted). The melting point of the low-melting fiber 25d (fused part) is preferably 20 ° C. or lower than the melting point of the high-melting fiber 25c. Here, it is possible to prevent the entire surface of the first yarn material 11 from being covered with the fused yarn (after being melted and solidified) by using the fused yarn and another yarn material in combination as the covering yarn 24. By carrying out like this, the softness | flexibility of a 1st thread material can be hold | maintained suitably, for example, it can be made to meander suitably.

（滑り防止糸）
滑り防止糸２６は、芯糸２０よりも嵩高な糸材であり、芯糸２０にスパイラル状に巻装しつつ、第二糸材１２（後述）に接触可能に配置される（図３を参照）。このように滑り防止糸２６を芯糸２０に巻装することで、第二糸材１２に対する第一糸材１１のズレを極力阻止できる。ここで滑り防止糸２６の素材は特に限定しないが、紡績糸、フィラメント及び伸縮加工糸（仮撚加工糸や座屈糸）を例示できる。また滑り防止糸２６（材質）は特に限定しないが、植物系及び動物系の天然繊維、熱可塑性樹脂又は熱硬化性樹脂からなる化学繊維及びこれらの混繊糸を例示できる。 (Anti-slip thread)
The anti-slip thread 26 is a thread material that is bulkier than the core thread 20 and is disposed so as to be in contact with the second thread material 12 (described later) while being spirally wound around the core thread 20 (see FIG. 3). ). By winding the anti-slip yarn 26 around the core yarn 20 in this way, the displacement of the first yarn material 11 with respect to the second yarn material 12 can be prevented as much as possible. Here, the material of the anti-slip yarn 26 is not particularly limited, and examples thereof include spun yarn, filament, and stretchable yarn (false twisted yarn and buckling yarn). The anti-slip yarn 26 (material) is not particularly limited, and examples thereof include plant-based and animal-based natural fibers, chemical fibers made of thermoplastic resins or thermosetting resins, and mixed yarns thereof.

［第一糸材の作成］
図３を参照して、複数種類のカバリング糸（導電糸２２，被覆糸２４，滑り防止糸２６）を芯糸２０に対してスパイラル状に順次巻装することで第一糸材１１を作成する。ここで第一糸材１１中の導電糸２２の本数は特に限定しない。例えば本実施形態では、導電糸２２をシングルカバリングすることで、第一糸材１１の部品点数を抑えて製造コスト等を低減することもできる。また複数の導電糸２２を芯糸２０に巻装することもできる。例えば第一導電糸をＺ撚りにて巻装するとともに、第二導電糸をＳ撚りにて巻装する（ダブルカバリングする）。このように第一導電糸と第二導電糸のカバリング方向を異ならせることで、第一糸材１１の構造を安定化しつつ、第二糸材１２（後述）との糸長差をより確実に発生させることができる。また本実施形態の構成に従えば、複数の導電糸２２を芯糸２０に対して同方向に巻装することもでき、後述する被覆糸２４で各導電糸２２の飛び出しを抑制できる。こうして導電糸２２（典型的に収縮しにくい糸材）を巻装することで、第一糸材１１の収縮性が、第二糸材１２よりも劣ることとなる。 [Create the first thread material]
Referring to FIG. 3, the first yarn material 11 is created by sequentially winding a plurality of types of covering yarn (conductive yarn 22, covering yarn 24, anti-slip yarn 26) around the core yarn 20 in a spiral shape. . Here, the number of the conductive yarns 22 in the first yarn material 11 is not particularly limited. For example, in the present embodiment, the conductive yarn 22 is single-covered, so that the number of parts of the first yarn material 11 can be suppressed and the manufacturing cost and the like can be reduced. A plurality of conductive yarns 22 can be wound around the core yarn 20. For example, the first conductive yarn is wound with Z twist and the second conductive yarn is wound with S twist (double covering). Thus, by differentiating the covering directions of the first conductive yarn and the second conductive yarn, the length of the first yarn material 11 and the second yarn material 12 (described later) can be more reliably secured while the structure of the first yarn material 11 is stabilized. Can be generated. Further, according to the configuration of the present embodiment, a plurality of conductive yarns 22 can be wound around the core yarn 20 in the same direction, and the protruding of each conductive yarn 22 can be suppressed by the covering yarn 24 described later. In this way, by winding the conductive yarn 22 (typically a yarn material that hardly shrinks), the shrinkage of the first yarn material 11 is inferior to that of the second yarn material 12.

また導電糸２２のカバリング撚数は、導電糸の太さ（繊度）、狙いとする芯糸２０との伸度差などに応じて適宜設定できる。例えば導電糸２２の撚数を２００〜１５００Ｔ／ｍの範囲に設定することで、第一糸材１１に所望の強度を付与することができる。ここで導電糸２２の撚数が２００Ｔ／ｍ未満であると、導電糸２２が切断されるまでの伸度が十分得られない傾向にある。また導電糸２２の撚数が１５００Ｔ／ｍより多いと、第一糸材１１の剛性が高くなり、得られる織物の風合いや触感が過度に悪化することがある。そして導電糸２２の撚数を４００〜１０００Ｔ／ｍの範囲に設定することで、所望の性能を備えた第一糸材１１とすることができる。   Further, the covering twist number of the conductive yarn 22 can be appropriately set according to the thickness (fineness) of the conductive yarn, the elongation difference from the target core yarn 20, and the like. For example, desired strength can be imparted to the first yarn material 11 by setting the number of twists of the conductive yarn 22 in the range of 200 to 1500 T / m. Here, when the number of twists of the conductive yarn 22 is less than 200 T / m, the elongation until the conductive yarn 22 is cut tends to be insufficient. On the other hand, when the number of twists of the conductive yarn 22 is more than 1500 T / m, the rigidity of the first yarn material 11 is increased, and the texture and feel of the resulting fabric may be excessively deteriorated. And it can be set as the 1st thread material 11 provided with the desired performance by setting the twist number of the electrically conductive yarn 22 to the range of 400-1000 T / m.

（撚り係数）
つぎに被覆糸２４を、導電糸２２の上から芯糸２０に対してスパイラル状に巻装しつつ、導電糸２２を覆い隠すように配置する。ここで被覆糸２４のカバリング方向は特に限定しないが、導電糸２２をシングルカバリングする場合、導電糸２２のカバリング方向とは異なる方向であることが望ましい。被覆糸２４と導電糸２２のカバリング方向を異ならせることで、カバリングによるトルクの発生を好適に抑えることができる。そして芯糸２０に対する被覆糸２４の撚りの強さは、例えば下記の計算式１にて算出される撚り係数（糸の太さと関連付けた撚りの強さ）にて設定できる。本実施形態では、被覆糸２４の撚り係数を９０〜４６０の範囲に設定でき、好ましくは１００〜４５０の範囲、更に好ましくは１５０〜３００の範囲に設定する。例えば８４ｄｅｘの太さの被覆糸２４を使用する場合、撚数を１０００〜５０００Ｔ／ｍの範囲とすることで、撚り係数を上記範囲に設定できる。計算式１：Ｋ（係数）＝√（Ｄ／１０，０００）×Ｔ（Ｄは総デニール数（ｄｔｅｘ）、Ｔは撚数（Ｔ／ｍ）） (Twisting coefficient)
Next, the covering yarn 24 is disposed so as to cover the conductive yarn 22 while being spirally wound around the core yarn 20 from above the conductive yarn 22. Here, the covering direction of the covering yarn 24 is not particularly limited. However, when the conductive yarn 22 is single-covered, it is desirable that the direction is different from the covering direction of the conductive yarn 22. By making the covering directions of the covering yarn 24 and the conductive yarn 22 different, generation of torque due to covering can be suitably suppressed. The twist strength of the coated yarn 24 with respect to the core yarn 20 can be set by, for example, a twist coefficient (twist strength associated with the thickness of the yarn) calculated by the following calculation formula 1. In the present embodiment, the twist coefficient of the coated yarn 24 can be set in the range of 90 to 460, preferably in the range of 100 to 450, and more preferably in the range of 150 to 300. For example, when using the coated yarn 24 having a thickness of 84 dex, the twist coefficient can be set in the above range by setting the number of twists in the range of 1000 to 5000 T / m. Formula 1: K (coefficient) = √ (D / 10,000) × T (D is total denier number (dtex), T is twist number (T / m))

つぎに滑り防止糸２６を、被覆糸２４の上から芯糸２０に対してスパイラル状に巻装する（後述の第二糸材１２に接触可能に配置する）。ここで第一糸材１１中の滑り防止糸２６の本数やカバリング方向は特に限定しない。また滑り防止糸２６の撚数は、同糸の太さ（繊度）、フィラメント数（シングルカバリング、ダブルカバリング）などに応じて適宜設定できる。そして芯糸２０に対する滑り防止糸２６の撚りの強さは特に限定しないが、典型的に撚り係数を９〜１８０に設定でき、好ましくは２５〜１５０の範囲、更に好ましくは７５〜１２５の範囲に設定する。例えば８４ｄｅｘの太さの滑り防止糸２６を使用する場合、撚数を１００〜２０００Ｔ／ｍの範囲とすることで、撚り係数を上記範囲に設定できる。なお被覆糸２４の一部に滑り防止糸２６を用いる場合には、被覆糸２４の上から滑り防止糸２６を再度捲き装してもよく、また巻装しなくともよい。また滑り防止糸２６が第二糸材１２と接触可能である限り、芯糸２０と導電糸２２の上から、被覆糸２４と滑り防止糸２６を引き揃えで巻装してもよく、また被覆糸２４と滑り防止糸２６を一体化（例えば撚糸や混合）してから巻装することもできる。   Next, the anti-slip yarn 26 is spirally wound around the core yarn 20 from above the coated yarn 24 (arranged so as to be in contact with the second yarn material 12 described later). Here, the number of anti-slip yarns 26 in the first yarn material 11 and the covering direction are not particularly limited. Further, the number of twists of the anti-slip yarn 26 can be appropriately set according to the thickness (fineness) of the yarn, the number of filaments (single covering, double covering), and the like. The twist strength of the anti-slip yarn 26 with respect to the core yarn 20 is not particularly limited, but typically the twist coefficient can be set to 9 to 180, preferably in the range of 25 to 150, more preferably in the range of 75 to 125. Set. For example, when the anti-slip yarn 26 having a thickness of 84 dex is used, the twist coefficient can be set in the above range by setting the number of twists in the range of 100 to 2000 T / m. When the anti-slip yarn 26 is used as a part of the covering yarn 24, the anti-slip yarn 26 may be wound again over the covering yarn 24 or may not be wound. In addition, as long as the anti-slip yarn 26 can contact the second yarn material 12, the covering yarn 24 and the anti-slip yarn 26 may be wound on the core yarn 20 and the conductive yarn 22 in an aligned manner. The yarn 24 and the anti-slip yarn 26 can also be wound after being integrated (for example, twisted yarn or mixed).

そして第一糸材１１に熱処理を施しつつ、被覆糸２４の少なくとも一部（融着部位）を溶融固化させることにより、芯糸２０に対して導電糸２２を接着する。ここで熱処理のタイミングは特に限定しないが、揉み加工（液流リラックス加工等）を行う場合には、その揉み処理前に行うことが望ましい。こうすることで揉み加工時における導電糸２２の飛び出しや浮き上がりの発生を好適に阻止できる。なお熱処理は、第一糸材１１自体に施すことができ、後述の第一表皮ピース４０ｆの作成途中又は作成後に施すことができる。なお熱処理にて、融着部位を全て溶融させて不定形状とすることもできるが、融着部位を部分的に溶融させるなどして被覆糸２４の外形形状（糸材としての形状）を適度に維持することもできる。部分溶融は、熱処理中でも芯糸２０と導電糸２２の分離を抑える効果が残っているために有効である。   Then, the conductive yarn 22 is bonded to the core yarn 20 by melting and solidifying at least a part (fused portion) of the coated yarn 24 while heat-treating the first yarn material 11. Here, the timing of the heat treatment is not particularly limited. However, when the stagnation process (liquid flow relaxation process or the like) is performed, it is preferable to perform the process before the stagnation process. By doing so, it is possible to suitably prevent the conductive yarn 22 from jumping out or floating during stagnation. The heat treatment can be performed on the first thread material 11 itself, and can be performed during or after the creation of the first skin piece 40f described later. It is possible to melt the fused part completely into an indeterminate shape by heat treatment, but by appropriately melting the fused part, the outer shape of the coated yarn 24 (shape as the thread material) is appropriately set. It can also be maintained. Partial melting is effective because the effect of suppressing separation of the core yarn 20 and the conductive yarn 22 remains even during heat treatment.

［第二糸材］
第二糸材１２は、第一糸材１１よりも収縮しやすい糸材であり、紡績糸、フィラメント、延伸糸又は伸縮加工糸（仮撚加工糸や座屈糸）を例示できる（図２では、便宜上、個々の第二糸材１２ではなく同糸材が使用される組織部分に符号を付す）。ここで収縮とは、仮撚加工糸のように構造的なケン縮により縮むことも含む。第二糸材１２（材質）として、植物系及び動物系の天然繊維、熱可塑性樹脂又は熱硬化性樹脂からなる化学繊維及びこれらの混繊維を例示できる。ここで第一糸材１１と第二糸材１２の糸長差は特に限定しないが、第二糸材１２に対して第一糸材１１が１０％〜４５％長いことが望ましい。両糸材の糸長差が１０％未満であると、第一糸材１１が蛇行状に配置しないおそれがある。また両糸材の糸長差が４５％より大きいと、第二糸材１２の収縮により第一糸材１１が過度に引張されることがある。 [Second thread material]
The second yarn material 12 is a yarn material that is more easily contracted than the first yarn material 11, and can be exemplified by spun yarn, filament, drawn yarn, or stretchable yarn (false twisted yarn or buckled yarn) (in FIG. 2). For the sake of convenience, a reference numeral is given to the tissue portion in which the second yarn material 12 is used instead of the individual second yarn material 12). Here, shrinkage includes shrinkage due to structural squeeze like false twisted yarn. Examples of the second thread material 12 (material) include plant-based and animal-based natural fibers, chemical fibers made of thermoplastic resin or thermosetting resin, and mixed fibers thereof. Here, the yarn length difference between the first yarn material 11 and the second yarn material 12 is not particularly limited, but the first yarn material 11 is preferably 10% to 45% longer than the second yarn material 12. If the yarn length difference between the two yarn materials is less than 10%, the first yarn material 11 may not be arranged in a meandering manner. If the difference in yarn length between the two yarn materials is greater than 45%, the first yarn material 11 may be excessively pulled due to the contraction of the second yarn material 12.

［表皮材（第一表皮ピース）の作成］
第一表皮ピース４０ｆを、第一糸材１１と第二糸材１２を構成糸として使用しつつ作成する（図２を参照）。例えば織物の第一表皮ピース４０ｆを作成する場合、経糸としての第二糸材１２を整経したのち、緯糸としての第一糸材１１を適宜打ち込むことができる。また経糸として、第一糸材１１を使用することもできる。また編物（横編物等）の第一表皮ピース４０ｆを作成する場合、コース方向又はウェール方向の一部に第一糸材１１を導入できる。 [Creation of skin material (first skin piece)]
The first skin piece 40f is created using the first yarn material 11 and the second yarn material 12 as constituent yarns (see FIG. 2). For example, when creating the first skin piece 40f of woven fabric, the first yarn material 11 as the weft can be appropriately driven after warping the second yarn material 12 as the warp. Moreover, the 1st thread material 11 can also be used as a warp. When the first skin piece 40f of a knitted fabric (flat knitted fabric or the like) is created, the first yarn material 11 can be introduced into a part of the course direction or the wale direction.

本実施形態では、図５（ａ）の組織構成を参照して、織物の第一表皮ピース４０ｆを作成する。そして第一表皮ピース４０ｆのベースとなる部分を第二糸材（例えば経糸としての第二糸材１２ａ〜１２ｃ、緯糸としての第二糸材１２ｄ〜１２ｉ）にて形成する。このとき緯糸の一部に第一糸材１１を使用して、ベース部分の幅方向に沿うように織り込む。そして第二糸材１２ａ〜１２ｉにて誘導点１０ａ，１０ｂ及び拘束点１０ｃ（ともに後述）を形成することで、各第二糸材との収縮差により第一糸材１１を蛇行状に配置することとした。ここで第一糸材１１と交差させる各第二糸材（誘導点及び拘束点を構成する糸材）は、第一表皮ピース４０ｆの表面意匠を構成する糸材でもよく、表面意匠とは無関係の糸材でもよい。例えば表面意匠とは無関係の（表面側に現れない）各第二糸材を誘導点（１０ａ，１０ｂ）及び拘束点１０ｃの形成に用いることで、第一糸材１１の表面意匠への影響を極力排除できる。   In this embodiment, with reference to the structure | tissue structure of Fig.5 (a), the 1st skin piece 40f of a textile fabric is created. And the part used as the base of the 1st skin piece 40f is formed with the 2nd thread material (For example, the 2nd thread materials 12a-12c as a warp, The 2nd thread materials 12d-12i as a weft). At this time, the first yarn material 11 is used for a part of the weft and is woven along the width direction of the base portion. Then, by forming induction points 10a, 10b and restraint points 10c (both described later) with the second thread materials 12a to 12i, the first thread material 11 is arranged in a meandering manner due to a contraction difference from each second thread material. It was decided. Here, each second thread material (a thread material constituting the induction point and the restraint point) intersecting with the first thread material 11 may be a thread material constituting the surface design of the first skin piece 40f, and is independent of the surface design. May be used. For example, by using each second thread material unrelated to the surface design (not appearing on the surface side) for forming the induction points (10a, 10b) and the restraint points 10c, the influence on the surface design of the first thread material 11 is achieved. It can be eliminated as much as possible.

（誘導点）
誘導点（第一誘導点１０ａ，第二誘導点１０ｂ）は、第一表皮ピース４０ｆの面方向に第一糸材１１の変位を許容する部位であり、経糸一部（第二糸材１２ａ，１２ｃ）で構成される（図５（ａ）を参照）。ここで第二糸材１２ａと第二糸材１２ｃは第一糸材１１（緯糸）よりも外方に配置しており、第一表皮ピース４０ｆ表面からの第一糸材１１の飛び出しを規制できる。そして第一誘導点１０ａは、経糸の延びる方向で見て、第一糸材１１の一側（図５で見て上側）の糸飛ばし長さ（緯糸の飛ばし量）が、第一表皮ピース４０ｆの他の箇所に比べて大きい箇所である。また第二誘導点１０ｂは、経糸の延びる方向で見て、第一糸材１１の他側（図５で見て下側）の糸飛ばし長さが他の箇所に比べて大きい箇所である。 (Induction point)
The guide points (first guide point 10a, second guide point 10b) are portions that allow displacement of the first yarn material 11 in the surface direction of the first skin piece 40f, and a part of the warp yarn (second yarn material 12a, 12c) (see FIG. 5A). Here, the second yarn material 12a and the second yarn material 12c are arranged outward from the first yarn material 11 (weft yarn), and the first yarn material 11 can be prevented from protruding from the surface of the first skin piece 40f. . The first guiding point 10a has a yarn skipping length (weft skipping amount) on one side of the first yarn material 11 (upper side in FIG. 5) as viewed in the warp extending direction, and the first skin piece 40f. It is a place larger than other places. The second guiding point 10b is a portion where the yarn skipping length on the other side of the first yarn material 11 (the lower side in FIG. 5) is larger than the other portions when viewed in the direction in which the warp extends.

（拘束点）
拘束点１０ｃは、第一表皮ピース４０ｆの面方向に第一糸材１１の変位を許容する範囲が誘導点（１０ａ，１０ｂ）よりも小さい部位である（図５（ａ）を参照）。本実施形態の拘束点１０ｃは、経糸他部（第二糸材１２ｂ）で構成されており、第一誘導点１０ａと第二誘導点１０ｂの間に形成される。なお第二糸材１２ｂは第一糸材１１よりも外方に配置しており、第一表皮ピース４０ｆ表面からの第一糸材１１の飛び出しを規制できる。そして本実施形態の拘束点１０ｃは、経糸の延びる方向で見て、第一糸材１１一側の糸飛ばし長さが第一誘導点１０ａよりも小さく、また第一糸材１１他側の糸飛ばし長さが、第二誘導点１０ｂよりも小さい箇所である。 (Restriction point)
The restraint point 10c is a part where the range allowing the displacement of the first thread material 11 in the surface direction of the first skin piece 40f is smaller than the induction points (10a, 10b) (see FIG. 5A). The restraint point 10c of the present embodiment is composed of the warp other portion (second yarn material 12b) and is formed between the first induction point 10a and the second induction point 10b. In addition, the 2nd thread material 12b is arrange | positioned outward rather than the 1st thread material 11, and can control | jump out the 1st thread material 11 from the surface of the 1st skin piece 40f. The constraint point 10c of the present embodiment has a yarn skipping length on one side of the first yarn material 11 smaller than the first induction point 10a when viewed in the direction in which the warp extends, and a yarn on the other side of the first yarn material 11 The flying length is a portion smaller than the second guiding point 10b.

ここで拘束点１０ｃと誘導点１０ａ（１０ｂ）の間隔（一周期の長さ）は特に限定しないが、５〜３０ｍｍ程度が好ましく、より好ましくは１０〜２５ｍｍである。そして一周期の長さを５〜３０ｍｍ程度に設定することで、第一糸材１１（剛性に優れて蛇行しにくい導電糸）を好適に蛇行させることができる。また隣り合う拘束点１０ｃの間に、単数又は複数の誘導点（１０ａ又は１０ｂ）を形成できる。ここで隣り合う拘束点１０ｃの間の距離が広くなると第一糸材１１が引っかかりやすくなるため、隣り合う拘束点１０ｃの間に緯糸に対して複数本の誘導点となる経糸を配置してもよい。誘導点を複数形成する場合、各誘導点の糸飛ばし長さを同一とすることができ、また第一糸材１１の蛇行の位置（振幅の幅）に合わせて、各誘導点の糸飛ばし長さを適宜変えてもよい。   Although the space | interval (length of one period) of the restraint point 10c and the induction | guidance | derivation point 10a (10b) is not specifically limited here, About 5-30 mm is preferable, More preferably, it is 10-25 mm. By setting the length of one cycle to about 5 to 30 mm, it is possible to suitably meander the first thread material 11 (conductive thread that has excellent rigidity and is difficult to meander). Further, one or a plurality of induction points (10a or 10b) can be formed between the adjacent restraint points 10c. Here, since the first yarn material 11 is easily caught when the distance between the adjacent restraint points 10c is increased, warp yarns serving as a plurality of guide points for the wefts may be arranged between the adjacent restraint points 10c. Good. When a plurality of induction points are formed, the yarn skipping length of each induction point can be the same, and the yarn skipping length of each induction point can be matched to the meandering position (amplitude width) of the first yarn material 11. The thickness may be changed as appropriate.

なお第一表皮ピース４０ｆ中の第一糸材１１の配置本数は特に限定しないが、各種機能を好適に発揮させるために、複数の第一糸材１１を、所定間隔をあけつつ平行に配置することが好ましい（図２を参照）。例えば第一表皮ピース４０ｆにヒータ機能を持たせる場合、第一糸材１１同士の間隔寸法Ｗ１を１ｍｍ〜６０ｍｍに設定することができる。また第一表皮ピース４０ｆにセンサ（電極）機能を持たせる場合、第一糸材１１同士の間隔寸法Ｗ１を６０ｍｍの範囲内に設定することが望ましい。第一糸材１１同士の間隔寸法Ｗ１が６０ｍｍを超えると、第一表皮ピース４０ｆのセンサ機能が悪化（静電容量が低下）して電極として機能しないおそれがある。好ましくは第一糸材１１の間隔寸法Ｗ１の上限値を３０ｍｍとすることで、第一表皮ピース４０ｆがより好適なセンサ機能（静電容量）を備える。   In addition, although the arrangement | positioning number of the 1st thread material 11 in the 1st skin piece 40f is not specifically limited, In order to exhibit various functions suitably, the several 1st thread material 11 is arrange | positioned in parallel with predetermined intervals. Preferably (see FIG. 2). For example, when the first skin piece 40f is provided with a heater function, the interval dimension W1 between the first thread materials 11 can be set to 1 mm to 60 mm. When the first skin piece 40f is provided with a sensor (electrode) function, it is desirable to set the interval dimension W1 between the first thread materials 11 within a range of 60 mm. If the interval dimension W1 between the first thread materials 11 exceeds 60 mm, the sensor function of the first skin piece 40f is deteriorated (capacitance is reduced) and may not function as an electrode. Preferably, the first skin piece 40f has a more suitable sensor function (capacitance) by setting the upper limit value of the interval dimension W1 of the first thread material 11 to 30 mm.

（仕上げ処理）
そして第一表皮ピース４０ｆを作成したのち、所定の仕上げ処理を行うことで、各第二糸材との収縮差により第一糸材１１を蛇行状に配置させる（図２及び図５（ｂ）を参照）。この仕上げ処理として、精練工程と、染色工程と、熱セット工程と、風合い出し工程と、後加工剤付与工程と、仕上げセット工程を例示でき、これら上述の工程を全て行うこともでき、１又は複数の工程を省略することもできる。上記各工程では、第一表皮ピース４０ｆに熱処理（乾熱処理又は湿熱処理）を施すことが多く、例えば精練や染色工程では９０〜１５５℃前後の熱処理が施されることが多い。そしてこの加熱処理によって、第一表皮ピース４０ｆ中の各第二糸材が面方向に収縮する。また熱処理のほかに化学的な薬品による処理にて、各第二糸材が面方向に収縮することもある。なお第一表皮ピース４０ｆの収縮により、織物の地厚感や伸び付与、仕立て栄えにも効果がある。 (Finishing process)
Then, after the first skin piece 40f is created, the first thread material 11 is arranged in a meandering manner due to a contraction difference from each second thread material by performing a predetermined finishing process (FIGS. 2 and 5B). See). Examples of the finishing treatment include a scouring step, a dyeing step, a heat setting step, a texture-out step, a post-processing agent application step, and a finishing setting step, and all of the above-described steps can be performed. A plurality of steps can be omitted. In each of the above steps, the first skin piece 40f is often subjected to heat treatment (dry heat treatment or wet heat treatment). For example, in the scouring or dyeing step, heat treatment at around 90 to 155 ° C. is often performed. And by this heat treatment, each second thread material in the first skin piece 40f contracts in the surface direction. In addition to heat treatment, the second yarn material may shrink in the surface direction by treatment with a chemical agent. Note that the shrinkage of the first skin piece 40f is effective in providing a sense of fabric thickness, imparting elongation, and tailoring.

本実施形態では、上述の仕上げ処理において、各第二糸材が相対的に収縮することで、第一糸材１１（収縮性に劣る糸材）が蛇行状に撓み変形する。このとき第一糸材１１が、拘束点１０ｃにて拘束された箇所を支点として、誘導点１０ａ，１０ｂにおいて山なりに撓み変形する。すなわち第一糸材１１が、第一誘導点１０ａに沿って一側（図５で見て上側）に向けて山なりに撓み変形するとともに、第二誘導点１０ｂに沿って他側（図５で見て下側）に向けて山なりに撓み変形する。このように本実施形態では、誘導点１０ａ，１０ｂと拘束点１０ｃなどにて、第一糸材１１を面方向にスムーズに蛇行させることにより、第一表皮ピース４０ｆからの第一糸材１１の飛び出しを極力阻止できる。そして本実施形態では、滑り防止糸２６にて、第一糸材１１が拘束点１０ｃからずれることを極力阻止できる（所望の蛇行形状とすることができる）。   In the present embodiment, in the above-described finishing process, the second thread material relatively contracts, whereby the first thread material 11 (the thread material inferior in contractibility) is bent and deformed in a meandering manner. At this time, the first thread material 11 bends and deforms in a mountain shape at the guide points 10a and 10b, with the portion restrained at the restraint point 10c as a fulcrum. That is, the first thread material 11 is bent and deformed in a mountain-like manner toward the one side (upper side in FIG. 5) along the first induction point 10a, and the other side (FIG. 5) along the second induction point 10b. Deforms and deforms like a mountain toward the lower side. As described above, in the present embodiment, the first yarn material 11 from the first skin piece 40f is smoothly meandered in the surface direction at the induction points 10a, 10b, the restraint point 10c, and the like. Popping out can be prevented as much as possible. In the present embodiment, the anti-slip thread 26 can prevent the first thread material 11 from deviating from the restraint point 10c as much as possible (can have a desired meandering shape).

［表皮材の作成作業］
図２を参照して、第一表皮ピース４０ｆ（布材）の向きを調節するなどして、第一糸材１１をシート幅方向に向けつつ配置する。つぎに第一表皮ピース４０ｆ（布材）の両末端部に接続部材３０（帯状の布体）をそれぞれ配設する。ここで接続部材３０は、第一糸材１１と電源９を電気的につなげる部材であり、導線、導電テープ、導電化された布体を例示できる。そして各接続部材３０を、第一表皮ピース４０ｆに縫着しつつ、第一糸材１１の両端に電気的につなげる。そして一対の接続部材３０を、電源ケーブル（符号省略）などを介して電源９につなげることで、第一表皮ピース４０ｆを通電可能状態とすることができる。こうすることで表皮材４Ｓ（第一表皮ピース４０ｆ）を、例えばヒータとして機能させることができる（利便性に優れるシート構成となる）。そして複数の表皮ピース（第一表皮ピース４０ｆ，第一表皮ピース４０ｆなど）をミシン（図示省略）にて縫合しつつ袋状の表皮材４Ｓを作成することができる。 [Creation work of skin material]
With reference to FIG. 2, the first thread material 11 is arranged in the sheet width direction by adjusting the direction of the first skin piece 40 f (cloth material). Next, connecting members 30 (band-like cloth bodies) are respectively disposed at both end portions of the first skin piece 40f (cloth material). Here, the connection member 30 is a member that electrically connects the first thread material 11 and the power source 9, and can be exemplified by a conductive wire, a conductive tape, and a conductive cloth body. Each connecting member 30 is electrically connected to both ends of the first thread material 11 while being sewn to the first skin piece 40f. Then, the first skin piece 40f can be energized by connecting the pair of connection members 30 to the power source 9 via a power cable (reference number omitted) or the like. By doing so, the skin material 4S (first skin piece 40f) can be made to function as, for example, a heater (a sheet configuration having excellent convenience). Then, a bag-like skin material 4S can be created while sewing a plurality of skin pieces (first skin piece 40f, first skin piece 40f, etc.) with a sewing machine (not shown).

（表皮材の使用）
図１〜図３を参照して、表皮材４Ｓを、クッション材４Ｐ上に配置しつつ、ヒータ等として使用する。本実施形態の第一糸材１１では、被覆糸２４にて、芯糸２０に対する各導電糸２２の分離が極力抑えられる。このため本実施形態によれば、導電糸２２の飛び出しが原因の性能悪化（例えば導電糸の断線、異物感、温度ムラが生じること）を好適に阻止できる。そして本実施形態では、第一糸材１１が表皮材４Ｓに蛇行状に配置する。このため表皮材４Ｓの幅方向に力が加わったときでも、第一糸材１１（蛇行状）が直線となるように変形することで表皮材４Ｓが力を負担し、第一糸材１１に過度の力が加わらず断線を抑制できる。 (Use of skin material)
1 to 3, the skin material 4S is used as a heater or the like while being disposed on the cushion material 4P. In the first yarn material 11 of the present embodiment, the covering yarn 24 suppresses the separation of the conductive yarns 22 from the core yarn 20 as much as possible. For this reason, according to this embodiment, the performance deterioration (for example, a disconnection of a conductive yarn, a foreign material feeling, and a temperature nonuniformity) caused by jumping out of the conductive yarn 22 can be suitably prevented. In the present embodiment, the first thread material 11 is arranged in a meandering manner on the skin material 4S. For this reason, even when a force is applied in the width direction of the skin material 4S, the skin material 4S bears the force by deforming the first thread material 11 (meandering shape) into a straight line, and the first thread material 11 Disconnection can be suppressed without applying excessive force.

以上説明したとおり本実施形態では、導電糸２２を覆い隠す被覆糸２４（全部又は一部）を溶融固化させることにより、芯糸２０に対する導電糸２２の分離を極力抑えることができる。また本実施形態では、導電糸２２の表面を樹脂皮膜で覆うことにより、第一糸材１１の耐久性を向上させることができる。そして本実施形態では、滑り防止糸２６を芯糸２０に巻装することで、第二糸材１２に対する第一糸材１１のズレを極力阻止できる。このため本実施形態によれば、通電可能な第一糸材１１の性能をより向上させることができる。   As described above, in the present embodiment, the covering yarn 24 (all or a part) covering the conductive yarn 22 is melted and solidified, so that separation of the conductive yarn 22 from the core yarn 20 can be suppressed as much as possible. Moreover, in this embodiment, durability of the 1st thread | yarn material 11 can be improved by covering the surface of the electrically conductive thread | yarn 22 with a resin film. In this embodiment, the slippage of the first thread material 11 relative to the second thread material 12 can be prevented as much as possible by winding the anti-slip thread 26 around the core thread 20. For this reason, according to this embodiment, the performance of the 1st thread material 11 which can be supplied with electricity can be improved more.

［変形例］
本変形例では、芯糸２０が、被覆糸２４及び導電糸２２よりも融点が低い部位（融着部位）を有することができる。そして本変形例における芯糸２０（融着部位）の構成は、上述の実施形態における被覆糸（融着部位）の構成と同一とすることができる。また本変形例における被覆糸２４の構成は、上述の実施形態における芯糸の構成と同一とすることができる。 [Modification]
In the present modification, the core yarn 20 can have a portion (melting portion) having a lower melting point than the covering yarn 24 and the conductive yarn 22. And the structure of the core yarn 20 (fusion | fusion part) in this modification can be made the same as the structure of the covering yarn (fusion | fusion part) in the above-mentioned embodiment. Further, the configuration of the covering yarn 24 in the present modification can be the same as the configuration of the core yarn in the above-described embodiment.

［染色仕上げ加工後の導電糸の状況評価］
染色仕上げ加工後の各実施例の布材及び各比較例の布材について、外観目視にて導電糸の飛び出し又は浮きの有無を確認した。 [Situation evaluation of conductive yarn after dyeing finish]
About the cloth material of each Example after dyeing finishing and the cloth material of each comparative example, the presence or absence of the protruding or floating of the conductive yarn was visually confirmed.

［滑り防止糸の効果確認］
滑り防止糸の効果（本発明の第２発明の効果）を下記の手順にて確認した。仕上げ処理後の布材を用いて、蛇行１周期毎の第一糸材の長さ寸法を測定した（本試験では、蛇行１周期の波長を１４ｍｍに設定した）。つぎに第一糸材の長さ寸法の最大値（ＭＡＸ値）と、第一糸材の長さ寸法の最小値（ＭＩＮ値）の差（Ｒ値）を算出した。そしてＲ値が１．８ｍｍ（基準値）以下の場合を○、Ｒ値が１．８ｍｍを超える場合を×と評価した（なおＲ値が大きくなるほど布材中で第一糸材が滑っていることになる）。 [Confirmation of anti-slip yarn effect]
The effect of the anti-slip yarn (the effect of the second invention of the present invention) was confirmed by the following procedure. Using the fabric material after the finishing treatment, the length of the first thread material for each meandering cycle was measured (in this test, the wavelength of the meandering cycle was set to 14 mm). Next, the difference (R value) between the maximum value (MAX value) of the length dimension of the first thread material and the minimum value (MIN value) of the length dimension of the first thread material was calculated. The case where the R value was 1.8 mm (reference value) or less was evaluated as ◯, and the case where the R value exceeded 1.8 mm was evaluated as x (note that the first thread material slipped in the cloth material as the R value increased). )

［結果および考察］
実施例１〜４の布材では、被覆糸の効果により、染色仕上げ加工後において第一糸材の構造変化（導電糸の飛び出し又は浮き）が見られなかった。そして実施例１〜４では、導電糸が均一に巻かれていることから、均一な温度分布が得られることが容易に予測される。以上の結果から、各実施例によれば、通電可能な第一糸材の性能をより向上させることができたことがわかった。これとは異なり比較例１及び２の布材では、染色仕上げ加工後に導電糸と芯糸が分離して、導電糸の飛び出しが見られた。また比較例３の布材では、染色仕上げ加工後に導電糸と芯糸が分離して、導電糸の浮きが見られた。そして比較例１〜３の布材では、導電糸の飛び出し部分や浮き部分で単位面積当たりの導電糸量が多くなることから、布材の当該部分に温度上昇部が見られるなどして、均一な温度分布が得られないことが容易に予測される。 [Results and Discussion]
In the fabric materials of Examples 1 to 4, due to the effect of the covering yarn, the structural change (the jumping or floating of the conductive yarn) of the first yarn material was not observed after the dyeing finish processing. In Examples 1 to 4, since the conductive yarn is wound uniformly, it is easily predicted that a uniform temperature distribution is obtained. From the above results, it was found that according to each example, the performance of the first thread material capable of being energized could be further improved. On the other hand, in the fabric materials of Comparative Examples 1 and 2, the conductive yarn and the core yarn were separated after the dyeing finish processing, and the conductive yarn jumped out. Further, in the fabric material of Comparative Example 3, the conductive yarn and the core yarn were separated after the dyeing finish processing, and the conductive yarn was lifted. And in the cloth material of Comparative Examples 1-3, since the amount of the conductive yarn per unit area increases in the protruding part and the floating part of the conductive yarn, the temperature rising part is seen in the part of the cloth material, and so on. It is easily predicted that an accurate temperature distribution cannot be obtained.

下記［表４］に、滑り防止糸の効果試験の結果を示す。

Table 4 below shows the results of the effect test of the anti-slip yarn.

［表４］を参照して、実施例３の第一糸材は、基準値よりも低いＲ値を有することがわかった。この結果から、滑り防止糸を第一糸材に巻き付けることにより、第一糸材（導電糸）表面に凹凸が形成されて滑り防止性が向上することがわかった。これにより導電糸に電気を導通させると、より均一に布材の表面が温められることが容易に推測される。   With reference to [Table 4], it was found that the first yarn material of Example 3 had an R value lower than the reference value. From this result, it was found that when the anti-slip yarn is wound around the first yarn material, irregularities are formed on the surface of the first yarn material (conductive yarn) and the anti-slip property is improved. Thus, when electricity is conducted to the conductive yarn, it is easily estimated that the surface of the cloth material is warmed more uniformly.
