Description

  The present invention relates to a fabric structure. More specifically, the present invention relates to a fabric structure in which a non-conductive thread and a conductive thread are sewed on a fabric and can be used as various products such as various wirings, electrodes, and pressure sensors.

  Conventionally, a conductive thread is sewn into a fabric and used as a product such as a wiring, an electrode, or a pressure sensor. For example, the electrode members are arranged in the vertical and horizontal directions so that the electrode surfaces appear alternately on the front and back surfaces of the sheet-like pressure-sensitive conductive material, and the intersection of the electrode members sandwiches the pressure-sensitive conductive material from both sides. A configured distributed pressure sensor is known (for example, see Patent Document 1). In addition, a resistance value is applied by pressurization between an upper cloth part and a lower cloth part having an electrode part made of a plurality of conductive threads that are sewn to a non-conductive cloth part in a straight line and in parallel with a main stitch. In addition, there is known a pressure-sensitive sensor in which a spacer whose electric capacitance value changes is sandwiched (see, for example, Patent Document 2).

Japanese Patent No. 2569433 JP 2009-42108 A

  In the distributed pressure sensor described in Patent Document 1, an electrode in which a copper wire is gold-plated or the like is sewn into a pressure-sensitive conductive material (see FIG. 8) and is sewn by hand sewing or a dedicated sewing machine. Become. However, productivity is low in hand-sewing. In addition, when a dedicated sewing machine is used, the electrode member sewn into the pressure-sensitive conductive material is greatly bent, and particularly deformed greatly at the boundary between the inside and the surface of the pressure-sensitive conductive material (see FIG. 9). ). Therefore, the electrode may be disconnected by repeated pressurization and decompression. In addition, the pressure-sensitive sensor described in Patent Document 2 has a large number of parts, such as an upper cloth part having an electrode part, a lower cloth part, and a spacer sandwiched between these parts, has a complicated structure, and is difficult to manufacture. I don't get it.

  The present invention has been made in view of the above-described conventional situation, and a non-conductive thread and a conductive thread are sewn on a fabric and can be used as various products such as various wirings, electrodes, and pressure sensors. It is an object to provide a fabric structure.

6). The first conductive yarn and the second conductive yarn are arranged so as to intersect when the fabric is viewed in plan, and the first conductive yarn is composed of the second conductive yarn and the second non-conductive yarn. 4. The position locked to the first non-conductive yarn at a position avoiding the position locked to the first non-conductive thread. Or 5. The fabric structure described in 1.

In the fabric structure of the present invention, the first non-conductive thread is sewn from one side of the fabric, the first conductive thread is sewn from the other side, and the first conductive thread is locked to the first non-conductive thread at a plurality of locations. ing. For this reason, the movement of the first conductive thread is small and the deformation amount is small as compared to when one conductive thread is sewn into the fabric. As a result, a fabric structure in which the first conductive yarn is difficult to break can be obtained.
In addition, the length of the straight portion of the first conductive yarn between the one bent portion locked to the first non-conductive yarn and the other bent portion adjacent to the one bent portion of the first conductive yarn. (La) is longer than the length (Lb) of the first conductive yarn constituting one bent portion (La> Lb), and the length (La) of the straight portion of the first conductive yarn constitutes another bent portion. When the length of the first conductive yarn is longer than the length (Lc) (La> Lc), the length of the straight portion of the first conductive yarn is longer than the length of each bent portion locked to the first non-conductive yarn. long. As a result, the first conductive yarn moves less and the deformation amount is smaller. As a result, a fabric structure in which the first conductive yarn is more difficult to break can be obtained.
Further, the first non-conductive thread and the first conductive thread are sewn by a sewing machine. When the first non-conductive thread is an upper thread and the first conductive thread is a lower thread, the upper thread and lower thread of the sewing machine The deformation of the yarn is suppressed by the tension, and in particular, the movement and deformation of the first conductive yarn that is the lower yarn are further suppressed. In addition, since the first conductive yarn is usually more rigid than the first non-conductive yarn, this also suppresses movement and deformation during sewing as compared to the first non-conductive yarn. As a result, the first conductive yarn is less likely to be disconnected, and a fabric structure in which more portions of the first conductive yarn are disposed on the surface on the other surface side of the fabric can be obtained.
In addition, a second non-conductive thread sewn from the other side of the fabric and a second conductive thread sewn from the one side of the fabric are further provided, and the second conductive thread becomes a second non-conductive thread at a plurality of locations. When locked, the first conductive yarn and the second conductive yarn can be used as sensors such as various wirings, switches, electrodes, and pressure sensors, for example, and more useful fabric structures can do.
Furthermore, the second non-conductive thread and the second conductive thread are sewn by a sewing machine. When the second non-conductive thread is an upper thread and the second conductive thread is a lower thread, the upper thread and lower thread of the sewing machine The deformation of the yarn is suppressed by the tension, and in particular, the movement and deformation of the second conductive yarn that is the lower yarn are further suppressed. In addition, since the second conductive yarn is usually more rigid than the second nonconductive yarn, this also suppresses movement and deformation during sewing as compared to the second nonconductive yarn. As a result, the second conductive yarn is less likely to be disconnected, and a fabric structure in which more portions of the second conductive yarn are disposed on the surface on one side of the fabric can be obtained.
The first conductive yarn and the second conductive yarn are arranged so as to intersect when the fabric is viewed in plan, and the first conductive yarn is engaged with the second non-conductive yarn. When it is locked to the first non-conductive yarn at a position avoiding the position, the contact between the first conductive yarn and the second conductive yarn can be reliably prevented. Therefore, the first conductive yarn and the second conductive yarn can be used as, for example, a pressure sensor having electrodes facing each other through the fabric, and a more useful fabric structure can be obtained.

Hereinafter, the present invention will be described in detail with reference to FIGS.
The items shown here are for illustrative purposes and exemplary embodiments of the present invention, and are the most effective and easy-to-understand explanations of the principles and conceptual features of the present invention. It is stated for the purpose of providing what seems to be. In this respect, it is not intended to illustrate the structural details of the present invention beyond what is necessary for a fundamental understanding of the present invention. It will be clear to those skilled in the art how it is actually implemented.

  The fabric structure 100 of the present invention includes a fabric 1, a first nonconductive thread 21 sewn from one side 1 a of the fabric 1, and a first conductive thread 31 sewn from the other side 1 b of the fabric 1. . Further, the first conductive yarn 31 is locked to the first non-conductive yarn 21 at a plurality of locations (see the locking portion A in FIG. 1) (see FIG. 1 and the first conductive yarn on the other surface side of the fabric 1). (Refer to FIG. 5 showing the arrangement at predetermined intervals).

  Various fabrics can be used as the fabric 1. The fabric 1 is not particularly limited, and may be a woven fabric having any woven structure such as plain weave, twill weave, satin weave and the like. Moreover, the material of the thread | yarn used for the fabric 1 is not specifically limited, either. For example, various yarns made of plant-based materials such as cotton and hemp, and animal-based materials such as silk, regenerated fibers such as rayon, semi-synthetic fibers such as acetate, and synthetic fibers made of synthetic resins such as polyamide and polyester. Is mentioned. These yarns may be used alone or in combination of two or more.

  The first non-conductive thread 21 sewn from the one surface 1a of the fabric 1 may also be a non-conductive thread, and the material is not particularly limited. As the 1st nonelectroconductive thread | yarn 21, the thread | yarn which uses the fiber of the various materials similar to the thread | yarn used for the above-mentioned fabric 1 can be used. Further, the yarn used as the first non-conductive yarn 21 may be the same material as the yarn used for the fabric 1 or may be a different material.

The material of the first conductive thread 31 sewn from the other surface side 1b of the fabric 1 is not particularly limited. The first conductive yarn 31 is a conductive fibrous material that can be energized. In particular, the first conductive yarn has a specific resistance (volume resistivity) of 100 to 10 ⁻¹² Ω · cm measured in accordance with JIS K 7194. 31 can be used. As such a 1st conductive thread 31, the metal wire which consists of stainless steel, such as gold | metal | money, silver, copper, a copper alloy, platinum, iron, and SUS304, SUS316, SUS316L, for example can be used. Furthermore, a metal wire made of zinc, tin, nickel, aluminum, aluminum alloy, tungsten, or the like can also be used. Of these metal wires, stainless steel metal wires are preferable because they have excellent corrosion resistance and strength. The first conductive yarn 31 may be a single wire or a stranded wire.

  The wire diameter of the first conductive yarn 31 is not particularly limited. Although the wire diameter depends on the use of the fabric structure 100 and the like, it is preferably 10 to 500 μm, particularly preferably 20 to 100 μm from the viewpoint of strength and flexibility. If the wire diameter of the first conductive yarn 31 is in the above-described range, particularly 20 to 100 μm, it can be easily deformed when being sewn to the fabric 1 and can be locked to the first non-conductive yarn 21. Furthermore, after sewing, it is preferable because it is not easily disconnected.

  Further, the first conductive yarn 31 is, for example, a composite in which another fiber material such as polyester fiber is used as a core yarn, a metal wire is used as a sheath yarn, and a metal wire is wound around at least one of S and Z. It may be in the form of a thread. As this metal wire, a metal wire having a resin coating (electrically insulating coating) on its surface can also be used. Furthermore, the resin used for coating is not particularly limited. For example, polyurethane resin, acrylic resin, silicone resin, polyester resin and the like can be mentioned, and polyurethane resin is preferable from the viewpoint of durability. In the case of a metal wire on which this resin coating is applied, the resin coating at a required location can be removed by a method such as irradiation with a laser beam and used as an electrode or the like.

  As the first conductive yarn 31, a plated wire can be used. As this plating wire, a non-conductive or conductive fiber material is used as a core, and a wire having a plating layer formed over the entire length or a part in the width direction of the surface of the core. Can be used. The metal used for plating may be a single metal or an alloy. Thus, by forming a plating layer on the surface of the core material, the first conductive yarn 31 can be used even if the core material is a non-conductive fiber material. On the other hand, when the core material is a conductive fiber material, the durability of the first conductive yarn 31 can be improved by forming a plating layer.

  Various carbon fibers can also be used as the first conductive yarn 31. Examples of the carbon fiber include polyacrylonitrile-based carbon fiber (PAN-based carbon fiber) and pitch-based carbon fiber. Among these carbon fibers, carbon fibers such as carbonized fibers, graphitized fibers, and graphite fibers produced at a firing temperature of 1000 ° C. or higher are preferable because they have excellent electrical conductivity.

  The first conductive yarn 31 is locked to the first non-conductive yarn 21 at a plurality of locations (see the locking portion A in FIG. 1). That is, the first non-conductive thread 21 sewn from the one surface side 1a of the fabric 1 is caught by the first conductive thread 31 sewn from the other surface side 1b of the fabric 1, and the other surface of the first conductive thread 31 of the fabric 1 is sewn. The escape to the side 1b is prevented. This also means that the first non-conductive yarn 21 is locked to the first conductive yarn 31 at a plurality of locations. Thereby, the 1st electroconductive thread | yarn 21 is hooked on the 1st nonelectroconductive thread | yarn 21, and the slipping out of the 1st nonelectroconductive thread | yarn 21 to the 1 surface 1a of the fabric 1 is prevented.

  The locking portion A may be at a plurality of locations, and usually depends on the length of wiring and electrodes, the pitch at the time of sewing, etc., but usually at least several locations, for example, 5 locations or more, especially 10 locations or more It is. Moreover, when wiring etc. are long, it may be several hundred places or more, and very many places beyond it.

  In addition, among the first conductive yarns 31, one bent portion (see one bent portion 31b in FIG. 2) locked to the first non-conductive yarn 21 and another bent adjacent to the one bent portion 31b. The length (La) of the straight portion (see the straight portion 31a in FIG. 2) of the first conductive yarn 31 between the portion (see the other bent portion 31c in FIG. 2) is the first constituting the one bent portion 31b. It is longer than the length (Lb) of one conductive yarn 31 (La> Lb). Furthermore, the length (La) of the straight portion 31a of the first conductive yarn 31 is longer than the length (Lc) of the first conductive yarn 31 constituting the other bent portion 31c (La> Lc). As described above, it is preferable that the straight portion 31a is longer than the adjacent bent portions 31b and 31c because the portion of the entire length of the first conductive yarn 31 that may be deformed and disconnected may be reduced.

  Furthermore, it is preferable that the first conductive yarn 31 has a total length of the straight portions that is longer than a total length of the bent portions in the total length. That is, it is preferable that the amount of deformation at the bent portion is smaller and the number of deformed portions that may be broken is smaller. Thereby, for example, when used for applications such as a pressure sensor, disconnection of the first conductive yarn 31 due to repeated deformation of the fabric structure 100 due to pressurization and depressurization is more reliably suppressed.

  As described above, in order to make the length of the bent portion of the first conductive yarn 31 shorter, the first conductive yarn 31 is locked by the first non-conductive yarn 21 in the thickness direction of the fabric structure 100. The position is preferably a position closer to the surface of the other surface side 1b. Thereby, the sum total of the length of the bending part of the 1st conductive yarn 31 becomes shorter, and the disconnection of the 1st conductive yarn 31 by the deformation | transformation of the fabric structure 100, etc. is suppressed more. In addition, many portions of the first conductive yarn 31 are exposed on the surface of the other side 1b of the fabric 1 (see FIG. 5). Therefore, when the surface of the fabric 1 is observed with a camera or the like, it is possible to more easily confirm the arrangement state of the first conductive yarn 31 compared to the conventional configuration in which one conductive yarn is sewn into the fabric. it can.

  A method for sewing the first non-conductive thread 21 and the first conductive thread 31 to the fabric 1 is not particularly limited, but is preferably sewn with a sewing machine. As the sewing machine used at this time, a special sewing machine for exclusive use is not necessary, and a general sewing machine can be used. In the sewing machine, the upper thread is large in both movement and deformation, and the lower thread is smaller in movement and deformation than the upper thread. Therefore, when sewing with a sewing machine, it is preferable to use the first non-conductive thread 21 as an upper thread and the first conductive thread 31 as a lower thread. In this way, movement and deformation of the first conductive thread 31 are reduced when sewing, and thread breakage of the first conductive thread 31 during sewing can be suppressed. Further, since the first conductive yarn 31 is higher in rigidity than the first non-conductive yarn 21, when the first non-conductive yarn 21 hooks the first conductive yarn 31 and pulls it to the one surface side 1a of the fabric 1, the first conductive yarn 31 The conductive yarn 31 is not easily deformed, and the length of the bent portion can be shortened. Thereby, the disconnection of the first conductive yarn 31 when the deformation of the fabric structure 100 is repeated is more reliably suppressed.

  The fabric 1 includes a first non-conductive thread 21 and a first conductive thread 31, a second non-conductive thread 22 sewn from the other surface side 1b, and a second conductive thread 32 sewn from the one surface side 1a. It may further be provided (see FIGS. 3 and 6, where the second conductive yarn 32 is drawn with a broken line in FIG. 6 means that the back side of the fabric 1 is not visible in the figure. ). In this case, the second conductive yarn 32 is locked to the second non-conductive yarn 22 at a plurality of locations. The second non-conductive yarn 22 may be a non-conductive yarn, and the material is not particularly limited, and yarns using fibers of various materials similar to those used for the fabric 1 described above are used. can do. The yarn used as the second non-conductive yarn 22 may be the same material as the yarn used for the fabric 1 or may be a different material. Further, the first non-conductive yarn 21 and the second non-conductive yarn 22 may be made of the same material or different materials.

  The material of the second conductive yarn 32 is not particularly limited, and various conductive yarns used as the first conductive yarn 31 described above can be used. Further, the first conductive yarn 31 and the second conductive yarn 32 may be made of the same material or different materials. The second conductive yarn 32 may also be a single wire or a stranded wire.

  The second conductive yarn 32 is locked to the second non-conductive yarn 22 at a plurality of locations. That is, the second non-conductive thread 22 sewn from the other surface side 1b of the fabric 1 is caught by the second conductive thread 32 sewn from the one surface side 1a of the fabric 1, and the one surface side of the fabric 1 of the second conductive thread 32 The escape to 1a is prevented. This also means that the second non-conductive yarn 22 is locked to the second conductive yarn 32 at a plurality of locations. Accordingly, the second non-conductive yarn 22 is caught by the second non-conductive yarn 22, and the second non-conductive yarn 22 is prevented from coming out to the other surface side 1b of the fabric 1.

  The second non-conductive yarn 22 and the second conductive yarn 32 may be provided with a plurality of engaging portions. The meaning of the plurality of locations is defined by the first non-conductive yarn 21 and the first conductive yarn 31 described above. This means the same as having a plurality of locking portions.

  Further, of the second conductive yarn 32, one bent portion (see one bent portion 32b in FIG. 4) locked to the second non-conductive yarn 22 and another bent adjacent to the one bent portion 32b. The length (Lx) of the straight portion (see the straight portion 32a in FIG. 4) of the second conductive yarn 32 between the portion (see the other bent portion 32c in FIG. 4) is the first constituting the one bent portion 32b. 2 longer than the length (Ly) of the conductive yarn 32 (Lx> Ly). Further, the length (Lx) of the straight portion 32a of the second conductive yarn 32 is longer than the length (Lz) of the second conductive yarn 32 constituting the other bent portion 32c (Lx> Lz). This is preferable because the portion of the entire length of the second conductive yarn 32 that may be deformed and disconnected is reduced.

  Further, the total length of the straight portions of the second conductive yarn 32 is longer than the total length of the bent portions, that is, the amount of deformation due to the bent portion is smaller, and disconnection is possible. It is preferable that there are fewer deformable parts. Thereby, as mentioned above, the disconnection by the deformation | transformation etc. of the fabric structure 100 when used for specific applications, such as a pressure sensor, is suppressed more reliably.

  The second non-conductive thread 22 and the second conductive thread 32 are also sewn with a sewing machine, and it is preferable that the second non-conductive thread 22 is an upper thread and the second conductive thread 32 is a lower thread. Thereby, the movement and deformation of the second conductive thread 32 are reduced when sewing. Also in this case, since the second conductive yarn 32 has higher rigidity than the second non-conductive yarn 22, when the second non-conductive yarn 22 hooks the second conductive yarn 32 and pulls it to the one surface side 1a of the fabric 1, The second conductive yarn 32 is not easily deformed, and the length of the bent portion can be further shortened. Thereby, the disconnection of the second conductive yarn 32 when the deformation of the fabric structure 100 is repeated is more reliably suppressed.

  The first conductive yarn 31 and the second conductive yarn 32 are arranged so as to intersect when the fabric 1 is viewed in plan, and the first conductive yarn 31 has the second conductive yarn 32 that is the second non-conductive. It is locked to the first non-conductive thread 21 at a position avoiding the position locked to the thread 22 (see FIG. 3). In this way, contact between the first conductive thread 31 sewn on the other surface side 1b of the fabric 1 and the second conductive thread 32 sewn on the one surface side 1a can be reliably prevented.

  Further, the first conductive yarn 31 is pressed by the second non-conductive yarn 22 on the other surface side 1 b of the fabric 1. On the other hand, on the one surface side 1 a of the fabric 1, the first non-conductive yarn 21 is pressed by the second conductive yarn 32. Thereby, even if a sewing pitch is large, the float from the surface of the fabric 1 of the 1st electroconductive thread 31 and the 1st non-conductive thread 21 is suppressed.

  Moreover, if it carries out as mentioned above, the 1st conductive thread 31 and the 2nd conductive thread 32 can be made into respectively independent wiring, for example, can function as one electrode, the other electrode, etc. In this way, the fabric structure 100 can be used for applications such as a pressure sensor by detecting a change in capacitance value when the fabric 1 is pressurized. Further, if conductive particles such as carbon black are blended in the fabric 1, a change in the electrical resistance value between the electrodes when the fabric 1 is pressurized is detected, and similarly used for applications such as a pressure sensor. Can do.

  If the first conductive thread 31 and the second conductive thread 32 are locked at the same position, the first conductive thread 31 and the second conductive thread 32 may come into contact as shown in FIG. . In this case, despite having the first conductive thread 31 sewn from the other surface side 1b of the fabric 1 and the second conductive thread 32 sewn from the one surface side 1a, each can function independently. For example, it cannot be used as an electrode for a pressure sensor or the like.
