Description

Technical Field

[0001] The present invention relates to a conductive wiring and a method for manufacturing the same. Background Art

[0002] As we all know, the winding wire connecting the landline phone and the handset has always been spiral, so it has good tracking performance and the conductive wire is not easy to break. In addition, some devices reduce the slack of the wiring by winding the conductive wire or conductive fiber in a spiral shape on the telescopic core, improving the handling performance.

[0003] However, when the spiral wiring is twisted in the opposite direction of the spiral, there are problems with structural collapse and wiring entanglement. In addition, in the spiral structure in which the conductive wire or conductive fiber is wound on the core, the core and the spiral structure are offset and separated due to friction or expansion and contraction, and there is a problem of wire breakage. Therefore, in order to cover the entire spiral structure, the outside needs to be covered with resin / tube / braid, and in order to prevent the internal structure from being exposed, it must be easy to process. However, as the outer diameter of these wirings increases and the structure becomes harder, the wiring becomes difficult to bend and twist, and the expansion rate decreases, resulting in problems that hinder the tracking performance.

[0004] On the other hand, in so-called wearable clothing and the like in which an instrument for measuring blood pressure, pulse, etc. is assembled, a conductive thread or conductive material is used to connect the instrument for measuring blood pressure, pulse, etc. with a communication mechanism for transmitting data taken out of the instrument to the outside. In Patent Document 1, as conductive threads, carbon-based conductive threads, metal or alloy plated threads, conductive resin fiber threads, metal fiber threads, etc. are proposed. In Patent Document 2, nylon threads mixed with conductive carbon microparticle threads are proposed. In Patent Document 3, threads obtained by cutting a metal vapor-deposited film on the surface of a polyester film vapor-deposited with metals such as gold and silver are proposed. In Patent Document 4, flexible electrodes are proposed as electrodes used in wearable clothing.

[0034] The present invention is a conductive wiring containing a coiled wire and a chain stitch. The coiled wire is used, for example, as a winding wire connected between the main body and the receiver of a landline telephone. The coiled wire of the present invention is not only a winding wire, but can also be thicker or thinner, and can also use any coil shape. Chain stitches can be formed by chain sewing, and also include chain weaving as the basis of warp knitting. The chain stitch is chain-sewn continuously, and the conductive wire is sewn into the loop of the chain stitch, and the conductive wire and the chain stitch are integrated. Sewing into the loop of the chain stitch means that the coiled wire is contained and combined in the chain stitch. As a result, the coiled wire has good tracking properties with the grey cloth, and there will be no excess slack and no kinking, making it a conductive wiring that is easy to use.

[0035] The coiled electric wire is preferably sewn into the loop continuously or intermittently at a ratio of 1 to 10 loops of the chain stitching thread. Thus, the followability of the coiled electric wire to the original fabric can be controlled.

[0036] There may be a core wire inside the coil of the coiled wire. The thickness of the core wire is preferably 0.01 to 20 mm in diameter. The core wire is preferably a stretchable wire or a non-stretchable wire. When a stretchable wire is used as the core wire, stretchability can be given to the conductive wiring. This stretchability is a controlled stretchability within a range with the length of the stretch limit of the chain stitch as the upper limit and the length of the compression limit of the coil of the coiled wire as the lower limit. When the length of the compression limit of the coil of the coiled wire is set to 100%, it can be extended in a range of approximately 101 to 300%. When a non-stretchable wire is used as the core wire, not only the dimensional stability of the coiled wire can be improved, but also the reinforcement effect of the coiled wire can be improved. The material of the stretchable wire is preferably rubber, polyurethane, silicone, thermoplastic elastomer, conjugated multifilament composed of synthetic fibers, etc. The material of the core wire can also use the same material as the material of the chain stitch described later.

[0037] The chain stitch is preferably continuously chain stitched on the sheet material (the object to be sewn). The sheet material (the object to be sewn) may be any one of paper, resin sheet material, resin film, fabric, woven fabric, non-woven fabric, etc. In the case of wearable clothing, the chain stitch may also be sewn on the raw fabric of the clothing or its auxiliary materials (such as belts, reinforcing cloth, protective cloth, etc.). Alternatively, the chain stitch may also tear the sheet material (the object to be sewn) along the sheet material (the object to be sewn) to take out the conductive wiring.

[0038] The manufacturing method of the conductive wiring of the present invention uses a sewing machine to chain-stitch in such a way that the loops of the chain-stitch thread are continuously formed on one side of the sheet. An example of the sewing machine is a chain-stitch handle embroidery machine sold by Tajima Industries, under the trade name TCMX series. However, the inventors have the idea of ​​sewing the coiled electric wire into the loop of the chain-stitch thread to make it integrated, and further arranging a core wire inside the coil of the coiled electric wire.

[0039] As chain stitches, natural fibers such as cotton, linen, wool, and silk, synthetic fibers such as polyester, nylon, acrylonitrile, vinylon, polyolefin, para-aramid, meta-aramid, polyarylate, and polybenzoxazole, regenerated fibers such as rayon, rubber, polyurethane, silicone, and thermoplastic elastomers are preferred. The wire or thread used to impart conductivity to the chain stitch portion may be any conductive raw material such as copper wire, aluminum wire, stainless steel wire, tungsten (W), molybdenum (Mo), and metal-plated fiber. The chain stitches may be filament yarns or staple yarns. As an example, polyester conjugated multifilaments obtained by composite spinning of different types of polyesters such as polyethylene terephthalate and polybutylene terephthalate may also be used. As a commercially available product, there is a product name "T400" manufactured by Toray Industries, Inc. In addition, for the coil-shaped core, a stretch band for handicrafts covered with a braid on a rubber thread, or a processed product using a braid or twisted thread may also be used. The preferred diameter of the chain suture is 10 μm to 3 mm.

[0040] The chain stitch preferably includes a high-melting point synthetic fiber thread having a melting point of 200°C or more and a low-melting point synthetic fiber thread having a melting point of less than 200°C, and the melting point synthetic fiber thread is melt-bonded. Thus, the chain stitch raw material can be dissolved and bonded to the core wire or the blank, thereby preventing the displacement of the coiled wire raw material caused by stretching or friction that the chain stitch structure alone cannot withstand. As the high-melting point synthetic fiber thread, for example, there is a polyethylene terephthalate multifilament having a melting point of about 260°C, and as the low-melting point synthetic fiber thread, for example, there is a copolymer nylon thread having a melting point of about 70°C.

[0041] The thickness of the coiled wire is preferably 0.005 to 10 mm in diameter. The diameter of the coil is preferably 0.02 to 40 mm. The coiled wire can be any one of copper wire, aluminum wire, stainless steel wire, tungsten (W), molybdenum (Mo), metal-plated fiber, etc. The wire can use a bare wire or a coated wire. In the case of a coated wire, the coating can be any one of rubber, resin, rubber containing reinforcing fibers, resin containing reinforcing fibers, etc. The coiled wire material is preferably straight. If a straight wire is sewn into the loop of a chain stitch to integrate the chain stitch, it is fixed in the loop of the chain stitch at a predetermined distance (for example, 2 to 20 mm), and is free at other times, so it becomes a coil. As a raw material for the coiled wire, a twisted pair cable formed by twisting two coated wires is preferably used. The reason is that when the wires used to transmit electrical signals are parallel, when a magnetic field is generated by the electromagnetic waves of air noise, an electromotive force is generated, an induced current is generated, and it becomes a noise source. As a countermeasure, by twisting two or more wires together, the electromotive force will work in the opposite direction each time the twist occurs, and the electromotive force will cancel out the noise, thereby reducing the influence of air noise. By using this twisted wire as the raw material of the coil wire, a coil-shaped wire with good tracking performance and reduced noise can be obtained.

[0042] In addition, the following materials can be used as conductive wires: a substrate obtained by laminating a thin and soft base film with insulating properties such as polyimide, which is called a flexible printed circuit substrate or flexible printed wiring board (FPC), and a conductive metal such as copper foil, on which one or more circuits are formed to obtain a substrate, and the substrate is processed into a narrow shape, which is called a long FPC; a wiring printed with conductive ink on a resin sheet or resin film, etc., is processed into a narrow shape; a strip obtained by cutting a conductive foil or non-woven fabric, paper, resin sheet, resin film, etc. into a narrow shape. The width of these narrow conductive wires is preferably 0.05 to 15 mm, and the thickness is preferably 0.01 to 3 mm.

[0043] The present invention uses bare conductive wires such as uncoated insulated metal wires or metal-plated fibers, narrow conductive strips, etc. for the coil-shaped part, and can be used as electrodes in contact with the skin in wearable clothing and electrical stimulation treatment devices for measuring pulse and myoelectric potential. In addition, the coil-shaped part can be wound in one or more strands at the same time. When the bare conductive wires are wound in such a way that they are in contact with each other, and when they are sewn on a grey cloth, the circuit increases and the current becomes easier to flow. Moreover, in the case where uncoated insulated metal wires or metal-plated fibers are also used in the chain stitch part in addition to the coil-shaped part, the bare conductive wires are in contact with each other, so the circuit increases and the current becomes easier to flow. In the case of sewing to the grey cloth, since the coil-shaped part is arranged on the surface and the chain stitch is arranged on the back, the circuit from the surface to the back can also be ensured. The conductive wiring can be sewn on the grey cloth and used directly, or it can be used after the fabric is torn, dissolved, or separated. For example, a twisted yarn can be used for the coil-shaped part, or a twisted yarn of conductive metal wire or fiber and water-soluble vinylon can be used for the coil-shaped part and the chain stitch part. After wiring manufacturing, the water-soluble vinylon is dissolved and removed to expose the conductive raw material, thereby increasing the contact points between the conductive raw materials and increasing the number of circuits.

[0044] In the following drawings, the same reference numerals represent the same objects. Figure 1 1 is a schematic process diagram for explaining a chain stitch 4 chain-sewn on a sheet material used in one embodiment of the present invention. 1 is a chain stitch manufacturing device for forming the chain stitch 4. It shows a case where the direction of the hook 2 and the curved needle 5 is flipped 180 degrees relative to the conveying direction P. That is, for the purpose of explanation, it is turned upside down. In this case, even if the hook 2 switches to move downward after reaching the uppermost point, since the direction of the hook portion 2a of the hook 2 is opposite to the conveying direction P of the sheet material (sewn object) A, the supply yarn B remains engaged with the hook portion 2a of the hook 2 and moves together with the hook 2, and the loop 3 is pushed down in the direction opposite to the conveying direction P.

[0045] Then, when the hook 2 penetrates the sheet (object to be sewn) A downward, it falls off the hook portion 2a of the hook 2. At this time, since the hook 2 is located inside the loop 3a of the supply yarn B, the loop 3 formed by the next supply yarn B being pulled up into a ring is pulled up from the inside 3a of the previous loop 3. By repeating this, on the upper surface A1 of the sheet (object to be sewn) A, continuous loops 3 are connected in a chain shape to form a chain stitch 4. The sheet (object to be sewn) A is located between the loop 3 and the yarn 3b on the back side, forming a sewing hole 6. In the case where the sheet (object to be sewn) A is paper, it is easy to tear along the sewing hole 6, and the sheet (object to be sewn) A can be removed. In this way, the chain stitch 4 monomer that is chain-sewn can be taken out. When the coiled electric wire described below is sewn into the loop of the chain stitch to integrate the chain stitch, or when a core wire further exists inside the coil of the coiled electric wire, the sheet (work) A can be removed in the same manner.

In this way, the wiring with the covered wire and the chain stitching integrated is produced.

[0050] Example

[0051] The present invention is further described in detail using the following examples. The present invention should not be limited to the following examples.

[0052] In the following embodiments, the chain stitch sewing machine used is a chain stitch handle embroidery machine sold by Tajima Industries, Ltd. under the trade name TCMX-600.

[0053] (Example 1)

[0054] (1) Chain stitch

[0055] As the chain stitch thread, one polyester conjugated multifilament (manufactured by Toray Industries, trade name "T400") having a total fineness of 330 decitex and 68 filaments (diameter of about 0.3 mm) was used.

[0056] (2) Wires

[0057] As the covered electric wire, 7 wires with a conductor diameter of 0.08 mm / wire, a conductor material of tinned copper wire, a covering resin of vinyl chloride resin, and an outer diameter of 0.65 mm were used.

[0058] (3)Core raw materials

[0059] As a core material, 10 polyester conjugated multifilaments having a total fineness of 330 decitex and 68 filaments (manufactured by a company, trade name "T400") were aligned and used.

[0060] (4) Fabrication of Conductive Wiring

[0061] Use kraft paper with a thickness of 50 μm as the backing paper, such as Fig. 9 As shown, a core wire is further placed inside the coil of the coiled electric wire to integrate the chain stitching. Fig.10 This is a side view of the state where the chain sewing is performed together with the stabilizer and a core wire is further arranged inside the coil of the coiled electric wire, with the lower half of the stabilizer removed along the sewing machine hole. Fig.11 is from Fig.10 A side view of the state after all the stabilizing paper is removed along the sewing machine holes.

[0062] Then, the conductive wiring was heat-treated at 100°C for 2 minutes to make it show the stretchability of the polyester conjugated multifilament (Toray T400) of the chain stitch and the core material. The heating method used steam from an iron if it was a wet method, and a heat gun if it was a dry method. Thus, after the coated wire loop was made, the density of the coil per unit length was increased, and the wiring with improved followability was obtained. Fig.12 This is a photograph showing the stretchability of the core and chain stitch after heat treatment.

[0063] The resulting conductive wiring is suitable for wearable clothing.

[0064] (Example 2)

[0065] (1) Chain stitch

[0066] As the chain suture, a core made of tungsten 33 μm (uncoated) and polyester (PET) multifilament: total fineness 155 decitex, 48 filaments, and a sheath made of polyester (PET) multifilament: total fineness 83 decitex, 36 filaments are used, and the twisted wire (diameter about 0.2 mm) is coated in such a way that the tungsten is exposed.

[0067] (2) Wires

[0068] As the electric wire, a core made of tungsten 33 μm (uncoated) and polyester (PET) multifilament: total fineness 165 decitex, number of filaments 48, and a sheath made of polyester (PET) multifilament: total fineness 83 decitex, number of filaments 36 were used, and the wires were twisted in such a way that the tungsten was exposed.

[0069] (3)Core raw materials

[0070] As the core material, a silicon tube (inner diameter 0.5 mm, outer diameter 1 mm) was used.

[0071] (4) Fabrication of Conductive Wiring

[0072] As the sewing fabric, a polyester felt fabric is used. The conductive wiring may be used directly in a state of being sewn on the fabric, or may be used after being separated by tearing the fabric, dissolving it, or the like.

[0073] Fig.13 This is a plane photograph of the state of the coil-shaped part (the surface of the grey fabric) sewn on the grey fabric. Fig.14 This is a flat photo of the chain stitch part (back side of the grey fabric) sewn on the fabric. Fig.15 This is a side view photograph of the wiring being separated from the grey fabric. On the surface of the core, it can be seen that the front and back surfaces are gone, and the coil-shaped portion and the chain stitch portion are intertwined.

[0074] The resulting conductive wiring is suitable for wearable clothing.

[0075] By using bare conductive wires of metal wires without insulation coating in the coil-shaped portion, the conductive wiring of this embodiment can be used as wearable clothing for measuring pulse and myoelectric potential, and as electrodes in contact with the skin in electrical stimulation therapeutic devices. In addition, the coil-shaped portion can be wound in one or more pieces at the same time. When the bare conductive wires are wound in such a way that they are in contact with each other, or when they are sewn onto a grey cloth, the circuit increases, and the current becomes easier to flow. Moreover, in addition to the coil-shaped portion, the chain-stitch portion also uses bare conductive wires of metal wires without insulation coating, so the bare conductive wires are in contact with each other, the circuit increases, and the current becomes easier to flow. When sewn onto the grey cloth, since the coil-shaped portion is arranged on the surface and the chain-stitch is arranged on the back, the circuit from the surface to the back can also be ensured. The conductive wiring can be sewn onto the grey cloth and used directly, or it can be used after the grey cloth is torn, dissolved, or separated.

[0076] (Example 3)

[0077] (1) Chain stitch

[0078] As the chain stitch thread, one polyester conjugate multifilament (manufactured by Toray Industries, trade name "T400") having a total fineness of 330 decitex and 68 filaments was used.

[0079] (2) Wires

[0080] As the coiled electric wire, a twisted pair cable was used, which was formed by twisting two coated electric wires. The twisted pair cable was formed by twisting seven coated electric wires, each with a conductor diameter of 0.08 mm, conductor material: tinned copper wire, coating resin: vinyl chloride resin, and an outer diameter of 0.65 mm.

[0081] (3)Core raw materials

[0082] As a raw material, nine polyester conjugated yarns (manufactured by Toray Industries, trade name "T400") having a total fineness of 330 decitex and 68 filaments were aligned.

[0083] (4) Fabrication of Conductive Wiring

[0084] As the sewing sheet, paper was used and torn off after sewing. The paper used was kraft paper with a thickness of 50 μm, and the stranded wire was chain-stitched together with the backing paper to form a coiled wire. A core wire was also arranged inside the coil. Then, all the paper was removed along the sewing machine hole, and the conductive wiring was heat-treated at 100°C for 2 minutes to show the stretchability of the polyester conjugated multifilament of the chain stitching wire and the core raw material.

[0085] The obtained conductive wiring is a coiled electric wire with good followability and reduced noise, and is suitable for wearable clothing.

[0086] (Example 4)

[0087] (1) Chain stitch

[0088] As a chain suture, a polyester (PET) multifilament with a total fineness of 165 decitex and 48 filaments and a low-melting point nylon (melting point or softening point 70°C) with a total fineness of 110 decitex and 12 filaments are arranged on a core, and a low-melting point (melting point or softening point 70°C) nylon with a total fineness of 110 decitex and 12 filaments are arranged on a sheath and twisted together.

[0089] (2) Wires

[0090] As the coil-shaped electric wire, four tungsten wires with a diameter of 11 μm (uncoated) were used as cores, and one water-soluble vinylon wire 132decitex was used as a sheath, and the wires were twisted so that the tungsten was exposed.

[0091] (3)Core raw materials

[0092] As the core material, six polyester conjugated yarns (manufactured by Toray Industries, trade name "T400") having a total fineness of 330 decitex and 68 filaments were used.

[0093] (4) Fabrication of Conductive Wiring

[0094] As the sewing sheet, a sheet having a thickness of 100 μm and a mass (unit area mass) of 20 g / m 2 The nonwoven fabric is made of polyester fiber. The coated twisted wire of the electric wire is chain-stitched together with the nonwoven fabric, and a core wire is further arranged inside the coil of the coiled electric wire. Then, it is immersed in hot water at 100°C to dissolve the water-soluble vinylon of the coiled yarn, making it show the stretchability of the polyester conjugated yarn, and melt the low-melting-point nylon of the chain stitch. Next, the nonwoven fabric is torn along the sewing machine hole and removed.

[0095] The obtained conductive wiring can prevent the displacement of the coiled wire material due to stretching and friction that the chain stitch structure alone cannot withstand by dissolving the chain stitch material and bonding it to the core wire and the blank fabric, and is suitable for wearable clothing.
