Description

本発明は、相対的に収縮率の高い高収縮糸および相対的に収縮率の低い低収縮糸を含む織物に関する。   The present invention relates to a fabric including a high shrinkage yarn having a relatively high shrinkage rate and a low shrinkage yarn having a relatively low shrinkage rate.

下記特許文献１に記載されるように、絶縁繊維（高収縮糸）および導電線材（低収縮糸）を有する織物が公知である。かかる特許文献１には、絶縁繊維で構成される所定箇所にその他の箇所よりも収縮しやすい収縮部を設け、当該収縮部の収縮により導電線材を平面方向に撓ませた構成の織物が記載されている。このように導電線材を平面方向に撓ませた状態とする（面に交差する方向に突出することを抑制する）ことにより、相対的に伸度の小さい導電線材の断線が防止できるというものである。   As described in Patent Document 1 below, a fabric having insulating fibers (high shrinkage yarn) and conductive wire (low shrinkage yarn) is known. Patent Document 1 describes a woven fabric having a configuration in which a contraction part that is more easily contracted than other parts is provided at a predetermined part constituted by insulating fibers, and the conductive wire is bent in the plane direction by contraction of the contraction part. ing. Thus, by setting the conductive wire in a state of being bent in the plane direction (suppressing protruding in a direction intersecting the surface), disconnection of the conductive wire having a relatively small elongation can be prevented. .

特開２０１０−２６１１１６号公報JP 2010-261116 A

上記特許文献１に記載される織物は、相対的に収縮しやすい収縮部を設けなければならないため、当該収縮部がその他の部分よりも大きく収縮することによって意匠性が低下することがある。   Since the woven fabric described in Patent Document 1 must be provided with a contracted portion that is relatively easily contracted, the design may be deteriorated when the contracted portion contracts more than other portions.

上記実情に鑑みて、本発明が解決しようとする課題は、意匠性の低下を招くことなく低収縮糸の断線が防止される織物を提供することにある。   In view of the above circumstances, the problem to be solved by the present invention is to provide a woven fabric in which disconnection of a low shrinkage yarn is prevented without causing deterioration in design.

上記課題を解決するために本発明にかかる織物は、相対的に収縮率の高い高収縮糸および相対的に収縮率の低い低収縮糸を有する織物であって、面方向に沿う方向への変位を許容する誘導部が前記高収縮糸により形成され、前記低収縮糸は、その少なくとも一部が、前記誘導部に係合して面方向に沿って撓んだ状態にあることを要旨とする。   In order to solve the above problems, a fabric according to the present invention is a fabric having a high shrinkage yarn having a relatively high shrinkage rate and a low shrinkage yarn having a relatively low shrinkage rate, and is displaced in a direction along the surface direction. The guiding portion that allows the thread is formed by the high shrinkage yarn, and at least a part of the low shrinkage yarn is engaged with the guiding portion and is bent along the surface direction. .

上記構成によれば、高収縮糸によって形成される面方向に沿う方向への変位を許容する誘導部により、高収縮糸が相対的に大きく縮むと低収縮糸が面方向へ誘導されて撓んだ状態となるから、低収縮糸の断線が防止される。従来のように高収縮糸を局所的に大きく縮ませたりする構成ではないため、織物の意匠性が低下することもない。   According to the above configuration, when the high shrinkage yarn contracts relatively greatly, the low shrinkage yarn is guided in the surface direction and bent by the guide portion that allows displacement in the direction along the surface direction formed by the high shrinkage yarn. As a result, disconnection of the low shrinkage yarn is prevented. Since it is not the structure which shrinks | contracts a high shrinkage yarn locally locally like the past, the design property of a textile fabric does not fall.

この場合、前記誘導部は、面方向に沿う所定方向への変位を許容する一または複数の誘導部と、面方向に沿う前記所定方向の反対方向への変位を許容する一または複数の誘導部と、が交互に形成されたものであり、前記低収縮糸は、その少なくとも一部が、前記誘導部に係合して面方向に沿って前記所定方向または前記所定方向の反対方向に向かって交互に撓んだ状態にあればよい。   In this case, the guide portion includes one or more guide portions that allow displacement in a predetermined direction along the surface direction, and one or more guide portions that allow displacement in the opposite direction of the predetermined direction along the surface direction. Are formed alternately, and at least a part of the low-shrinkage yarn engages with the guide portion toward the predetermined direction or a direction opposite to the predetermined direction along the surface direction. What is necessary is just to be in the state bent alternately.

上記構成のように一または複数の誘導部を所定方向およびその反対方向の変位を許容するように交互に形成すれば、低収縮糸が波のように交互に撓んだ状態となる。つまり、低収縮糸の長さ方向に撓んだ部分が略均等に形成される構成となるから、低収縮糸の耐荷重性などが向上する。   If one or a plurality of guide portions are alternately formed so as to allow displacement in a predetermined direction and the opposite direction as in the above configuration, the low shrinkage yarns are alternately bent like waves. That is, since the portion of the low shrinkage yarn bent in the length direction is formed substantially evenly, the load resistance of the low shrinkage yarn is improved.

また、前記誘導部を構成する前記面方向に沿う所定方向への変位を許容する誘導部と面方向に沿う前記所定方向の反対方向への変位を許容する誘導部との間の少なくとも一部には、前記低収縮糸が係合し、その変位を許容する範囲が前記誘導部よりも小さい拘束部が前記高収縮糸により形成されていればよい。   Further, at least a portion between the guide portion that allows displacement in a predetermined direction along the surface direction that constitutes the guide portion and the guide portion that allows displacement in the opposite direction of the predetermined direction along the surface direction. The low-shrinkage thread is engaged as long as the high-shrinkage thread has a constraining portion whose allowable range is smaller than that of the guide portion.

上記構成のように、変位を許容する範囲が誘導部よりも小さい拘束部を形成すれば、当該拘束部によって低収縮糸の位置ずれなどが抑制される。また、低収縮糸は、高収縮糸が縮むと、拘束部によって所定部位が押さえられた状態で、その所定部位の両側の部位が誘導部に誘導されて面方向に撓む。つまり、低収縮糸は、拘束部によって押さえられた部位が支点となってその両側の部位が平面方向に誘導されることになるため、低収縮糸が面に交差する方向に突出することを抑制する効果がさらに向上する。   As in the above-described configuration, if a restraint portion in which the range allowing displacement is smaller than that of the guide portion is formed, the restraint portion suppresses the position shift of the low shrinkage yarn. Further, when the high shrinkage yarn contracts, the low shrinkage yarn is bent in the plane direction by guiding the portions on both sides of the predetermined portion to the guide portion while the predetermined portion is pressed by the restraining portion. In other words, the low-shrinkage yarn is guided in the plane direction by using the part pressed by the restraining part as a fulcrum, so that the low-shrinkage thread is prevented from protruding in the direction crossing the surface. The effect to do is further improved.

また、上記織物は二重または多重織物であって、前記低収縮糸は厚み方向における一方側の層の一部を構成するものであればよい。   The woven fabric may be a double woven fabric or a multiple woven fabric, and the low shrinkage yarn only needs to constitute a part of one layer in the thickness direction.

このように二重または多重織物の裏面側の層に低収縮糸が配される構成であると、低収縮糸は厚み方向における一方側の面に沿って撓んだ状態となるため、厚み方向における他方側からは低収縮糸は不可視となる。つまり、厚み方向の他方側からは高収縮糸のみによって形成された織物に見えるため、意匠性に優れる。   In this way, when the low shrinkage yarn is arranged on the back side layer of the double or multiple fabric, the low shrinkage yarn is bent along the surface on one side in the thickness direction, so the thickness direction From the other side, the low shrinkage yarn is invisible. That is, since it looks like a woven fabric formed only from a high shrinkage yarn from the other side in the thickness direction, the design is excellent.

本発明によれば、意匠性の低下を招くことなく、低収縮糸の断線が防止される織物が得られる。   According to the present invention, it is possible to obtain a woven fabric in which disconnection of a low shrinkage yarn is prevented without causing deterioration in design properties.

本発明の実施形態について図面を参照しつつ説明する。本発明の実施形態にかかる織物１の用途例としては、車両用シートのシートカバーが挙げられる。以下、車両用シートのシートカバーとして使用される織物を例に各構成について詳細に説明する。   Embodiments of the present invention will be described with reference to the drawings. As an application example of the fabric 1 according to the embodiment of the present invention, a seat cover for a vehicle seat may be mentioned. Hereinafter, each configuration will be described in detail by taking a fabric used as a seat cover for a vehicle seat as an example.

本実施形態にかかる織物１は、高収縮糸２および低収縮糸３を備える。高収縮糸２は、相対的に（低収縮糸３よりも）収縮率の高い（収縮しやすい）材料で形成された糸である。低収縮糸３は、相対的に（高収縮糸２よりも）収縮率の低い（収縮しにくい）材料で形成された糸である。本実施形態にかかる織物１は、織物のベースとなる部分が高収縮糸２によって形成され、低収縮糸３はベース部分の幅方向に沿うように織り込まれたものである。高収縮糸２としては、公知の綿、麻、羊毛といった天然繊維や、ポリエステルやナイロンといった化学繊維が例示できる。低収縮糸３よりも収縮率が高いものであれば、高収縮糸２として複数種の糸を用いることができる。また、低収縮糸３としては、導電性金属や炭素繊維などの導電性線材が例示できる。車両用シートのシートカバーとして使用される織物においては、低収縮糸３として配される導電性線材は、通電によって発熱するヒータ線や乗員の着座の有無を検出するための静電容量式のセンサとして用いられる。   The fabric 1 according to this embodiment includes a high shrinkage yarn 2 and a low shrinkage yarn 3. The high shrinkage yarn 2 is a yarn formed of a material having a relatively high shrinkage rate (easy to shrink) (relative to the low shrinkage yarn 3). The low shrinkage yarn 3 is a yarn formed of a material having a relatively low shrinkage rate (less likely to shrink) (relative to the high shrinkage yarn 2). In the woven fabric 1 according to this embodiment, the base portion of the woven fabric is formed by the high shrinkage yarn 2, and the low shrinkage yarn 3 is woven along the width direction of the base portion. Examples of the high shrinkage yarn 2 include known natural fibers such as cotton, hemp and wool, and chemical fibers such as polyester and nylon. A plurality of types of yarns can be used as the high shrinkage yarn 2 as long as the shrinkage rate is higher than that of the low shrinkage yarn 3. Examples of the low shrinkage yarn 3 include conductive wires such as conductive metals and carbon fibers. In a woven fabric used as a seat cover for a vehicle seat, the conductive wire disposed as the low shrinkage yarn 3 includes a heater wire that generates heat when energized and a capacitance type sensor for detecting the presence or absence of a passenger seating. Used as

図１（ｂ）は、（図１（ａ）に示した織物に仕上げ処理を施してなる）本発明の第一実施形態にかかる織物１ａの平面図である。第一実施形態にかかる織物１ａには、高収縮糸２ａによって構成される誘導部２１ａが形成されている（図１〜図５においては、誘導部２１を構成する高収縮糸２にハッチングを施した上で、その高収縮糸２における誘導部２１となる部分にはクロスハッチングを施している）。誘導部２１ａは、面方向に沿う方向への変位を許容する部分である。別の見方をすれば、面に交差する方向（面から突出する方向）への変位を妨げる部分である。本実施形態では、誘導部２１ａは上下方向に沿うように配された高収縮糸２ａ（経糸）の一部によって構成されている。具体的には、当該高収縮糸２ａには、上下方向における糸飛ばし長さ（緯糸の飛ばし量）が、その他の箇所に比べて大きい箇所があり、当該箇所が誘導部２１ａとして機能する。   FIG. 1B is a plan view of the fabric 1a according to the first embodiment of the present invention (formed by finishing the fabric shown in FIG. 1A). In the fabric 1a according to the first embodiment, a guiding portion 21a constituted by the high shrinkage yarn 2a is formed (in FIGS. 1 to 5, the high shrinkage yarn 2 constituting the guiding portion 21 is hatched. In addition, the portion that becomes the guide portion 21 in the high shrinkage yarn 2 is cross-hatched). The guide portion 21a is a portion that allows displacement in a direction along the surface direction. From another viewpoint, it is a portion that prevents displacement in a direction intersecting the surface (a direction protruding from the surface). In the present embodiment, the guide portion 21a is constituted by a part of the highly shrinkable yarn 2a (warp yarn) arranged along the vertical direction. Specifically, the high shrinkage yarn 2a has a portion where the yarn skipping length (weft skipping amount) in the vertical direction is larger than other portions, and the portion functions as the guiding portion 21a.

低収縮糸３ａは、この誘導部２１ａの下を通るように配されている。つまり、低収縮糸３ａは、誘導部２１ａによって面に交差する方向に突出しないように押さえられた状態にある。誘導部２１ａに押さえられた状態で低収縮糸３ａが配された図１（ａ）に示す状態のものに対し、上記特許文献１（特開２０１０−２６１１１６号公報）に記載のような仕上げ処理（熱処理工程を含む）を施すと、高収縮糸２ａ（織物のベース部分）が低収縮糸３ａよりも大きく縮む。この収縮差によって低収縮糸３ａは撓むことになるが、誘導部２１ａによって押さえられているから、面に交差する方向に突出せずに図１（ｂ）に示すように面方向に撓む。つまり、収縮する織物のベース部分に追従して面方向に沿って撓んだ低収縮糸３ａが配された織物となる。   The low shrinkage yarn 3a is disposed so as to pass under the guide portion 21a. That is, the low shrinkage yarn 3a is in a state of being pressed so as not to protrude in the direction intersecting the surface by the guide portion 21a. A finishing process as described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2010-261116) is applied to the state shown in FIG. 1A in which the low shrinkage yarn 3a is disposed while being pressed by the guide portion 21a. When (including the heat treatment step) is performed, the high shrinkage yarn 2a (base portion of the woven fabric) contracts more than the low shrinkage yarn 3a. Although the low shrinkage yarn 3a bends due to this shrinkage difference, it is bent by the guiding portion 21a, so that it does not protrude in the direction intersecting the surface but bends in the surface direction as shown in FIG. . That is, the fabric is provided with the low shrinkage yarn 3a that is bent along the surface direction following the base portion of the fabric to be contracted.

図２（ｂ）は、（図２（ａ）に示した織物に仕上げ処理を施してなる）本発明の第二実施形態にかかる織物１ｂの平面図である。本実施形態にかかる織物１ｂは、高収縮糸２ｂによって、面方向に沿う上方向への変位を許容する誘導部（以下、第一誘導部２１１ｂと称することもある）と、面方向に沿う下方向への変位を許容する誘導部（以下、第二誘導部２１２ｂと称することもある）とが、幅方向に交互に形成されたものである。つまり、本実施形態にかかる織物１ｂは、面方向に沿う所定方向への変位を許容する誘導部と、その所定方向とは反対の方向への変位を許容する誘導部とが交互に形成されたものである。   FIG. 2B is a plan view of the fabric 1b according to the second embodiment of the present invention (formed by finishing the fabric shown in FIG. 2A). The fabric 1b according to the present embodiment includes a guiding portion (hereinafter, also referred to as a first guiding portion 211b) that permits displacement in the upward direction along the surface direction by the high shrinkage yarn 2b, and a bottom surface along the surface direction. Guide portions that allow displacement in the direction (hereinafter also referred to as second guide portions 212b) are alternately formed in the width direction. That is, in the fabric 1b according to the present embodiment, the guide portions that allow displacement in a predetermined direction along the surface direction and the guide portions that allow displacement in a direction opposite to the predetermined direction are alternately formed. Is.

本実施形態では、上方向への変位を許容する第一誘導部２１１ｂは、幅方向に並ぶ第二誘導部２１２ｂよりも上側に延びる部分を有する。下方向への変位を許容する第二誘導部２１２ｂは、幅方向に並ぶ第一誘導部２１１ｂよりも下側に延びる部分を有する。そして、第一誘導部２１１ｂの下側の一部と第二誘導部２１２ｂの上側の一部が上下方向で重なるように（上下方向における位置が同じとなるように）設定されている。   In the present embodiment, the first guide portion 211b that allows the upward displacement has a portion that extends above the second guide portion 212b that is aligned in the width direction. The second guide portion 212b that allows the downward displacement has a portion that extends below the first guide portion 211b arranged in the width direction. The lower part of the first guide part 211b and the upper part of the second guide part 212b are set so as to overlap in the vertical direction (so that the positions in the vertical direction are the same).

図２（ａ）に示すように、幅方向に沿って略真っ直ぐである仕上げ処理前の低収縮糸３ｂは、第一誘導部２１１ｂおよび第二誘導部２１２ｂにおける上下方向で重なる部分を通った状態にある。この状態で仕上げ処理が施されて高収縮糸２ｂが相対的に大きく縮むと、低収縮糸３ｂにおける第一誘導部２１１ｂの下を通る部分は、上方向への変位が許容されているから面方向に沿って上方向に撓む。一方、低収縮糸３ｂにおける第二誘導部２１２ｂの下を通る部分は、下方向への変位が許容されているから面方向に沿って下方向に撓む。このように、仕上げ処理が施され高収縮糸２ｂで構成された織物のベース部分が相対的に大きく縮むことにより、面方向に沿って上下方向に交互に撓んだ波形状となって低収縮糸３ｂが配された図２（ｂ）に示す織物１ｂが得られる。   As shown in FIG. 2A, the low-shrinkage yarn 3b before finishing, which is substantially straight along the width direction, passes through the overlapping portion in the vertical direction in the first guiding portion 211b and the second guiding portion 212b. It is in. When the finishing process is performed in this state and the high shrinkage yarn 2b is relatively greatly shrunk, the portion of the low shrinkage yarn 3b that passes under the first guide portion 211b is allowed to be displaced upward. Bends upward along the direction. On the other hand, the portion of the low-shrinkage yarn 3b that passes under the second guide portion 212b bends downward along the surface direction because the downward displacement is allowed. In this way, the base portion of the woven fabric composed of the high-shrinkage yarn 2b that has been subjected to the finishing treatment is relatively greatly contracted to form a wave shape that alternately bends in the vertical direction along the surface direction. A woven fabric 1b shown in FIG. 2B on which the yarn 3b is arranged is obtained.

なお、上記第二実施形態は、上方向（所定方向）への変位を許容する一の第一誘導部２１１ｂと、下方向（所定方向の反対方向）への変位を許容する一の第二誘導部２１２ｂとが交互に形成されていることを説明したが、二つの第一誘導部２１１ｂと二つの第二誘導部２１２ｂが交互に形成される構成のように、複数の第一誘導部２１１ｂと複数の第二誘導部２１２ｂとが交互に形成される構成としてもよい。また、一の第一誘導部２１１ｂまたは第二誘導部２１２ｂと、複数の第二誘導部２１２ｂまたは第一誘導部２１１ｂが交互に形成される構成としてもよい。   In the second embodiment, one first guide portion 211b that allows displacement in the upward direction (predetermined direction) and one second guide that allows displacement in the downward direction (the direction opposite to the predetermined direction). Although the portions 212b are alternately formed, the plurality of first guide portions 211b and the two first guide portions 211b and the two second guide portions 212b are alternately formed. A plurality of second guide portions 212b may be alternately formed. Moreover, it is good also as a structure by which the one 1st guide part 211b or the 2nd guide part 212b and the some 2nd guide part 212b or the 1st guide part 211b are formed alternately.

さらに、上記実施形態において、第一誘導部が上方向に許容する変位の大きさは、少なくとも下方向に許容する変位の大きさよりも大きければよく、第二誘導部が下方向に許容する変位の大きさは、少なくとも上方向に許容する変位の大きさよりも大きければよい。つまり、第一誘導部が下方向への変位を全く許容しないように形成され、第二誘導部が上方向への変位を全く許容しないように形成されていなければならないわけではない。   Furthermore, in the above-described embodiment, the magnitude of the displacement allowed by the first guide portion in the upward direction should be at least larger than the magnitude of the displacement allowed in the downward direction, and the displacement allowed by the second guide portion in the downward direction. The size should be at least larger than the size of the displacement allowed in the upward direction. In other words, the first guide portion does not have to be formed so as not to allow any downward displacement, and the second guide portion does not have to be formed so as not to allow any upward displacement.

図３（ｂ）は、（図３（ａ）に示した織物に仕上げ処理を施してなる）本発明の第三実施形態にかかる織物１ｃの平面図である。本実施形態にかかる織物１ｃは、高収縮糸２ｃによって、面方向に沿う上方向への変位を許容する第一誘導部２１１ｃと、面方向に沿う下方向への変位を許容する第二誘導部２１２ｃとが幅方向に交互に形成されるとともに、幅方向における第一誘導部２１１ｃと第二誘導部２１２ｃとの間に拘束部２２ｃが形成されたものである。   FIG. 3B is a plan view of the fabric 1c according to the third embodiment (formed by finishing the fabric shown in FIG. 3A). The fabric 1c according to the present embodiment includes a first guiding portion 211c that allows an upward displacement along the surface direction and a second guiding portion that allows a downward displacement along the surface direction by the high shrinkage yarn 2c. 212c are alternately formed in the width direction, and a restricting portion 22c is formed between the first guide portion 211c and the second guide portion 212c in the width direction.

拘束部２２ｃは、変位を許容する範囲が誘導部２１１ｃ、２１２ｃよりも小さい箇所である。したがって、低収縮糸３ｃにおける拘束部２２ｃの下に位置する部分には、低収縮糸３ｃにおける誘導部２１１ｃ、２１２ｃの下に位置する部分よりも摩擦力等によって大きな拘束力が発生する。本実施形態のように上下方向に沿う誘導部２１１ｃ、２１２ｃが形成された構成でいえば、拘束部２２ｃの上下方向における長さは、誘導部２１１ｃ、２１２ｃの上下方向における長さよりも小さい。つまり、拘束部２２ｃが低収縮糸３ｃの上下方向の変位を許容する範囲の大きさは、誘導部２１１ｃ、２１２ｃが許容する範囲の大きさよりも小さくなっている。また、本実施形態では、上下方向における各拘束部２２ｃの位置は、略同じ位置となるように設定されている。   The restraining part 22c is a place where the range in which the displacement is allowed is smaller than the guiding parts 211c and 212c. Therefore, a greater restraining force is generated in the portion of the low shrinkage yarn 3c located under the restraining portion 22c than the portion of the low shrinkage yarn 3c located under the guiding portions 211c and 212c due to a frictional force or the like. In the configuration in which the guide portions 211c and 212c along the vertical direction are formed as in the present embodiment, the length of the restraint portion 22c in the vertical direction is smaller than the length of the guide portions 211c and 212c in the vertical direction. That is, the size of the range in which the restraining portion 22c allows the vertical displacement of the low shrinkage yarn 3c is smaller than the size of the range allowed by the guide portions 211c and 212c. Moreover, in this embodiment, the position of each restraint part 22c in the up-down direction is set to be substantially the same position.

図３（ａ）に示すように幅方向に沿って略真っ直ぐである仕上げ処理前の低収縮糸３ｃは、第一誘導部２１１ｃ、第二誘導部２１２ｃ、および拘束部２２ｃの下を通った状態にある。この状態で仕上げ処理が施されて高収縮糸２ｃが相対的に大きく縮むと、拘束部２２ｃに拘束された箇所を支点として、低収縮糸３ｃにおける第一誘導部２１１ｃの下を通る部分が面方向に沿って上方向に撓み、低収縮糸３ｃにおける第二誘導部２１２ｃの下を通る部分が面方向に沿って下方向に撓む。特に本実施形態では、低収縮糸３ｃにおける拘束部２２ｃに拘束された箇所の一方側が上方向（所定方向）に撓み、他方側が下方向（所定方向の反対方向）に撓むから、拘束部２２ｃの一方側における上方向への撓み量と拘束部２２ｃの他方側における下方向への撓み量が略均等になる。   As shown in FIG. 3A, the low-shrinkage yarn 3c before finishing, which is substantially straight along the width direction, passes under the first guiding portion 211c, the second guiding portion 212c, and the restraining portion 22c. It is in. When the finishing process is performed in this state and the high shrinkage yarn 2c is relatively greatly contracted, the portion passing through the first guiding portion 211c in the low shrinkage yarn 3c is a surface with the portion restrained by the restraining portion 22c as a fulcrum. The portion of the low shrinkage yarn 3c that passes under the second guide portion 212c bends downward along the surface direction. In particular, in the present embodiment, one side of the portion of the low-shrinkage yarn 3c restrained by the restraining portion 22c bends upward (predetermined direction), and the other side bends downward (opposite direction of the predetermined direction). The amount of bending in the upward direction on one side and the amount of bending in the downward direction on the other side of the restraining portion 22c are substantially equal.

なお、本実施形態では、拘束部２２ｃは、第一誘導部２１１ｃと第二誘導部２１２ｃとの間の全てに形成されているが、両者の間の少なくとも一部に形成されていればよい。つまり、本実施形態にかかる織物１ｃは、面方向に沿う所定方向への変位を許容する第一誘導部２１１ｃと面方向に沿う所定方向の反対方向への変位を許容する第二誘導部２１２ｃとの間の少なくとも一部に、拘束部２２ｃが形成されたものであればよい。   In addition, in this embodiment, although the restraint part 22c is formed in all between the 1st guide part 211c and the 2nd guide part 212c, it should just be formed in at least one part between both. That is, the fabric 1c according to the present embodiment includes a first guiding portion 211c that allows displacement in a predetermined direction along the surface direction, and a second guiding portion 212c that allows displacement in the opposite direction to the predetermined direction along the surface direction. What is necessary is just to have the restraint part 22c formed in at least a part between.

また、図４（ｂ）に示す（参考として仕上げ処理前のものを図４（ａ）に示す）ように、複数の第一誘導部２１１ｄと複数の第二誘導部２１２ｄとが交互に形成され、その複数の第一誘導部２１１ｄと複数の第二誘導部２１２ｄとの間（の少なくとも一部）に、拘束部２２ｄが形成された織物としてもよい。つまり、拘束部２２ｄは、低収縮糸３ｄを所定方向へ撓ませようとする誘導部と、所定方向の反対方向に撓ませようとする誘導部との間の少なくとも一部に形成されていればよい。   Further, as shown in FIG. 4B (as shown in FIG. 4A, the pre-finishing process is shown as a reference), a plurality of first guiding portions 211d and a plurality of second guiding portions 212d are alternately formed. Further, a woven fabric in which a restraint portion 22d is formed between (at least a part of) the plurality of first guide portions 211d and the plurality of second guide portions 212d may be used. In other words, the restraining portion 22d is formed at least at a part between the guiding portion that tries to bend the low-shrinkage yarn 3d in a predetermined direction and the guiding portion that is intended to bend in the opposite direction of the predetermined direction. Good.

以上、低収縮糸３が係合する誘導部２１（第一誘導部２１１および第二誘導部２１２）や拘束部２２が高収縮糸２によって形成された本発明の実施形態にかかる織物１（１ａ〜１ｄ）について説明したが、これら誘導部２１や拘束部２２のピッチ等は適宜変更可能である。例えば、図５に示す織物１ｅを図３に示した織物１ｃと比較すれば分かるように、高収縮糸２ｅで形成される第一誘導部２１１ｅ、第二誘導部２１２ｅ、および拘束部２２ｅの間隔をさらに小さくすることにより、低収縮糸３ｅが小刻みに波打つように撓んだ状態で配される織物としてもよい。   As described above, the woven fabric 1 (1a) according to the embodiment of the present invention in which the guide portion 21 (the first guide portion 211 and the second guide portion 212) and the restraining portion 22 with which the low shrinkage yarn 3 is engaged are formed by the high shrinkage yarn 2. ˜1d) has been described, but the pitches of the guide portion 21 and the restraint portion 22 can be changed as appropriate. For example, as can be seen by comparing the woven fabric 1e shown in FIG. 5 with the woven fabric 1c shown in FIG. 3, the distance between the first guiding portion 211e, the second guiding portion 212e, and the restraining portion 22e formed by the high shrinkage yarn 2e. It is good also as a woven fabric distribute | arranged in the state which bent so that the low shrinkage yarn 3e may wave in small increments by making further smaller.

また、上記各織物は、低収縮糸３が厚み方向における一方側の層の一部を構成する二重織物または多重織物であるとよい。例えば、二重織物である場合には、図６に示すように、厚み方向の一方側の層である図の下側の層に低収縮糸３が配された（図の上側の層に低収縮糸３が配されていない）構成とすればよい。このようにすれば、厚み方向における一方側（例えば裏側）の面に沿って撓んだ低収縮糸３は、厚み方向における他方側（例えば表側）からは不可視となる。つまり、厚み方向の他方側からは高収縮糸２のみによって形成された織物に見えるため、意匠性に優れる。   Each of the woven fabrics may be a double woven fabric or a multiple woven fabric in which the low shrinkage yarn 3 constitutes a part of one layer in the thickness direction. For example, in the case of a double woven fabric, as shown in FIG. 6, the low shrinkage yarn 3 is arranged in the lower layer in the figure, which is one layer in the thickness direction (the lower layer is in the upper layer in the figure). The configuration may be such that the shrink yarn 3 is not disposed. In this way, the low shrinkage yarn 3 bent along the surface on one side (for example, the back side) in the thickness direction becomes invisible from the other side (for example, the front side) in the thickness direction. That is, since it looks like a woven fabric formed only by the high shrinkage yarn 2 from the other side in the thickness direction, the design is excellent.

以上説明した本実施形態にかかる織物によれば、高収縮糸によって形成される面方向に沿う方向への変位を許容する誘導部により、高収縮糸が相対的に大きく縮むと低収縮糸が面方向へ誘導されて撓んだ状態となるから、低収縮糸の断線が防止される。本実施形態は、従来のように高収縮糸を局所的に大きく縮ませたりする構成ではないため、織物の意匠性が低下することがない点で優れる。   According to the woven fabric according to the present embodiment described above, when the high shrinkage yarn is relatively largely contracted by the guiding portion that allows displacement in the direction along the surface direction formed by the high shrinkage yarn, the low shrinkage yarn is faced. Since it is guided in the direction and is bent, disconnection of the low shrinkage yarn is prevented. This embodiment is excellent in that the design property of the woven fabric is not deteriorated because it is not a configuration in which the high-shrinkage yarn is locally contracted greatly as in the prior art.

以下、具体的な実施例を用いて本発明を説明する。なお、本発明は以下の実施例に限定されるものではない。   Hereinafter, the present invention will be described using specific examples. In addition, this invention is not limited to a following example.

・第一実施例
高収縮糸として経糸に１６７ｄｔｅｘ７２フィラメントのＰＥＴの仮撚加工糸、緯糸に３３４ｄｔｅｘ７２フィラメントのＰＥＴの仮撚加工糸を用い、低収縮糸として炭素繊維Ｔ−３００（東レ株式会社製）を芯糸に３３４ｄｔｅｘ７２フィラメントのＰＥＴの仮撚糸をらせん状に二方向からカバリング（ダブルカバリング）した導電糸を用いて、上記図１〜図４に示した組織（以下、図１〜図４に示した組織のそれぞれを第一組織〜第四組織と称する）の織物を製織した。仕上げ処理前の織密度は２５．４ｍｍ四方で経糸／緯糸＝１６８本／１００本である。低収縮糸は、仕上げ処理前に上下方向に１０ｍｍピッチで織り込んだ。 First Example A PET false twisted yarn of 167 dtex 72 filaments as a warp yarn as a high shrinkage yarn, a PET false twisted yarn of PET as a 334 dtex 72 filament as a weft yarn, and carbon fiber T-300 (manufactured by Toray Industries, Inc.) as a low shrink yarn The structure shown in FIGS. 1 to 4 (hereinafter shown in FIGS. 1 to 4) is obtained by using a conductive yarn in which a PET false twisted yarn of 334 dtex 72 filaments is spirally covered (double covering) in two directions. Woven fabrics of the first structure to the fourth structure). The weaving density before finishing is 25.4 mm square and warp / weft = 168/100. The low shrinkage yarn was woven at a pitch of 10 mm in the vertical direction before finishing.

当該織物に液流染色機を用いて９０℃×２０ｍｍのリラックス熱処理工程を含む仕上げ処理を施した。仕上げ処理後の織密度は２５．４ｍｍ四方で経糸／緯糸＝２３３／１０８本となり、仕上げ処理前と比べて３９％（織物のベース部分が）収縮した。   The woven fabric was subjected to a finishing treatment including a relaxing heat treatment step of 90 ° C. × 20 mm using a liquid dyeing machine. The weaving density after the finishing treatment was 25.4 mm square and warp / weft = 233/108 yarns, shrinking by 39% (the base portion of the woven fabric) contracted compared to before the finishing treatment.

この仕上げ処理後の上記第一組織〜第四組織の織物における低収縮糸である導電糸をチェックしたところ、第一組織〜第四組織の織物の全てについて、導電糸が面方向に沿った波形状に撓んだ状態となっていることが確認された。ただし、当該「波」の周期や振幅を見ると、第一組織の織物が最もバラツキがあり、第三組織や第四組織の織物が最も均等である（きれいな「波」となっている）ことが確認された。第一組織の織物における導電糸の周期や振幅のバラツキが大きかったのは、全ての誘導部の上下方向における位置が同じであるためであると思われる。また、第二組織の織物における導電糸の周期や振幅のバラツキが第一組織の織物よりも小さかったのは、第一誘導部が上、第二誘導部が下にそれぞれ導電糸を誘導するようにジグザグに誘導部が形成されているためであると思われる。さらに、第三組織や第四組織の織物における導電糸の周期や振幅が最も均等であったのは、第一誘導部と第二誘導部との間に設けられた拘束部に拘束された部位を支点として導電糸が撓んだためだと思われる。   After checking the conductive yarns, which are low shrinkage yarns in the fabrics of the first structure to the fourth structure after the finishing treatment, for all the fabrics of the first structure to the fourth structure, the conductive yarns are waves along the surface direction. It was confirmed that the shape was bent. However, looking at the period and amplitude of the “wave”, the fabric of the first structure has the most variation, and the fabric of the third structure and the fourth structure are the most uniform (clean “wave”). Was confirmed. The reason for the large variation in the period and amplitude of the conductive yarn in the fabric of the first structure seems to be because the positions in the vertical direction of all the guiding portions are the same. In addition, the variation in the period and amplitude of the conductive yarn in the fabric of the second structure was smaller than that of the fabric of the first structure. The reason is that the first guide portion is guided upward and the second guide portion is guided downward. It seems that this is because the guide part is formed in the zigzag. In addition, the period and amplitude of the conductive yarn in the third structure and the fourth structure woven fabric were most uniform because the part was restrained by the restraining part provided between the first guiding part and the second guiding part. This is thought to be because the conductive yarn was bent around the fulcrum.

また、この仕上げ処理後の上記第一組織〜第四組織の織物について、低収縮糸である導電糸の断線の有無を調べたが、いずれの織物でも導電糸の断線は発生しなかった。なお、導電糸の断線の有無の調査は、０．６Ａで通電することによって導電糸を発熱させ、１分後に他の部分に比べて局所的に温度が高くなる部分（温度差が５℃以上になる部分）が生じた場合、または、通電不可であった場合を「断線」と判断するものである。   Moreover, although the presence or absence of the disconnection of the electrically conductive yarn which is a low shrinkage thread | yarn was investigated about the textile fabric of the said 1st structure-the 4th structure | tissue after this finishing process, the disconnection of the electrically conductive yarn did not generate | occur | produce in any textile fabric. In addition, the investigation of the presence or absence of breakage of the conductive yarn was conducted by heating the conductive yarn by energizing at 0.6 A, and the portion where the temperature became locally higher than the other portion after 1 minute (temperature difference of 5 ° C. or more) In the case where there is a portion that becomes or a case where energization is not possible, it is determined as “disconnection”.

・第二実施例
低収縮糸として線径２０μｍのＳＵＳ３１６線７本を１５００Ｔ／ｍで撚り、その撚り方向とは反対方向に３３４ｄｔｅｘ７２フィラメントにＰＥＴの仮撚糸をらせん状に二方向からカバリング（ダブルカバリング）した導電糸を用いて、上記図５に示した組織（以下、第五組織と称する）の織物を製織した。その他の条件は、第一実施例と同様である。 Second Example Seven SUS316 wires having a wire diameter of 20 μm are twisted at 1500 T / m as a low shrinkage yarn, and a PET false twisted yarn is covered with a 334 dtex 72 filament in a direction opposite to the twist direction from two directions in a spiral manner (double covering) ) Was used to weave a woven fabric having the structure shown in FIG. 5 (hereinafter referred to as the fifth structure). Other conditions are the same as in the first embodiment.

仕上げ処理後の織物をチェックしたところ、導電糸が面方向に沿った波形状に撓んだ状態となっていることが確認された。また、その「波」の周期や振幅が一定であることが確認された。   When the finished woven fabric was checked, it was confirmed that the conductive yarn was bent into a wave shape along the surface direction. It was also confirmed that the period and amplitude of the “wave” were constant.

また、仕上げ処理後の織物における低収縮糸である導電糸の断線は発生しなかった。   Moreover, the disconnection of the conductive yarn which is a low shrinkage yarn in the finished woven fabric did not occur.

・比較例
第一実施例および第二実施例と同じ材料を用い、図７に示す組織の織物を製織した。図７に示す組織は、端的に言えば、面方向への変位を許容する「誘導部」に相当する部分が形成されずに、高収縮糸（９１）によって面方向への変位をほとんど許容しない「拘束部」に相当する部分（９１１）のみが形成されたものである。 Comparative Example A woven fabric having the structure shown in FIG. 7 was woven using the same material as in the first and second examples. In short, the structure shown in FIG. 7 does not allow a portion corresponding to the “guide portion” that allows displacement in the surface direction, and hardly allows displacement in the surface direction by the high shrinkage yarn (91). Only the portion (911) corresponding to the “restraint portion” is formed.

仕上げ処理後の比較例にかかる織物は、低収縮糸である導電糸（９０）が面から突出するように撓み（突出した部分（９０ｘ））、断線が頻発してしまうことが確認された。拘束部は、低収縮糸を面方向に誘導する誘導部があってはじめて有利な方向に作用する部位であると認められた。   It was confirmed that the fabric according to the comparative example after the finishing treatment was bent so that the conductive yarn (90), which is a low shrinkage yarn, protruded from the surface (protruded portion (90x)), and disconnection occurred frequently. It was recognized that the restraining portion is a site that acts in an advantageous direction only when there is a guiding portion that guides the low shrinkage yarn in the surface direction.

以上、本発明の実施形態について詳細に説明したが、本発明は上記実施形態に何ら限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の改変が可能である。   As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment at all, A various change is possible in the range which does not deviate from the summary of this invention.
