However, fabrics containing conventional conductive threads have the problem that the fabric itself melts or burns and is damaged when terminals and conductive parts are formed by soldering, and it is necessary to use crimp terminals and button-type terminals. There was a problem that it could not be made thinner. Conventionally, there has been a method of securing contacts with a conductive resin or the like.

In order to solve the above conventional problems, the present invention provides a solderable article capable of forming threads containing metal filaments and organic fibers by soldering to a base material.

The soldering article of the present invention is a soldering article in which a thread containing metal filaments and organic fibers is fixed to a base material at a soldering portion, and the soldering portion melts the solder metal by ultrasonic soldering . and being fixed to the metal filament and the substrate in a solidified state.

The present inventors have studied twisting metal filaments such as tungsten (W) into fibrous structures such as woven fabrics and knitted fabrics. Here, in order to apply power to the metal filament and to obtain electric signals from the metal filament, a terminal portion and a conductive portion are required. However, conventional crimp terminals and button-type terminals are large, making it difficult to apply them to clothing, and when formed by conventional soldering, there is a problem that the cloth itself melts or burns and is damaged.
Therefore, the present inventor tried ultrasonic soldering, and surprisingly, it was possible to solder the fabric made of organic fiber yarn without melting, scorching, etc., and soldering the terminal part and the conductive part. can be made thinner and smaller. The reason for this is that when a fabric made of organic fiber yarn is ultrasonically soldered, the solder metal is melted by the ultrasonic soldering , penetrates into the fabric from the surface of the fabric, and adheres to the metal filament in a solidified state . However, it is presumed that the heat is diffused and radiated from the metal filament at this time. The yarn containing the metal filament and the organic fiber yarn of the present invention is wired on the surface of a substrate such as a fiber structure, resin molding, ceramics, glass, wood, synthetic paper, or a mixture thereof, and the substrate and the wiring are soldered. I also found that it can be attached.

The present invention is a soldered article in which a thread containing metal filaments and organic fibers is fixed to a base material at a soldering part, and the soldering part is in a state where the solder metal is melted by ultrasonic soldering and solidified. It adheres to the metal filament and the substrate. Threads containing metal filaments and organic fibers may be soldered to the substrate. The yarn containing metal filaments and organic fibers may be a component of the fiber structure as described above, or may be wired on the substrate surface.

As one embodiment of the present invention, a case where threads containing metal filaments and organic fibers are used as constituent elements of a fiber structure will be described. Yarns containing metal filaments and organic fibers are disposed between ground sections containing organic fiber yarns. Here, the base weave portion is a main weave portion that constitutes the fabric. Fabrics are woven or knitted fabrics and the like. A woven fabric is composed of warp and weft yarns, and yarns containing metal filaments are arranged in some of the warp yarns and weft yarns. Among knitted fabrics, in the case of weft knitting, the base structure of the weft yarn is composed of organic fiber yarn, the yarn containing the metal filament is arranged in the horizontal direction with a gap, and the metal filament is included in the vertical direction by inserting the warp yarn. Place the thread. In the case of warp knitting, the base structure of the warp yarn is composed of organic fiber yarn, the yarn containing the metal filament is arranged in the warp direction with a gap, and the yarn containing the metal filament is arranged in the weft direction by inserting the weft yarn.

A soldering part exists in a part of the fabric, and the soldering part melts the solder metal by ultrasonic soldering , penetrates into the fabric from the surface of the fabric, and solidifies with the metal filament. It's stuck. A part of the fabric has a soldered part because it serves as a terminal part or a conductive part. The soldered portions may be scattered at one point or at a plurality of points. For example, the ultrasonic solder has a frequency of 60 kHz ± 5 kHz, ultrasonic transmission output: rated 15 W (max) (effective 10 W (max)), heater temperature 200 to 500 ° C, power supply capacity: AC 100 V/240 V, 50/60 Hz, 150 W. be.

Organic fibers in the present invention include, for example, natural fibers such as cotton, hemp, wool, and silk; synthetic fibers such as polyester, nylon, acrylic, vinylon, polyolefin, para-aramid, meta-aramid, polyarylate, and polybenzoxazole; Includes regenerated fibers such as rayon. Among these, clothing fibers such as cotton, hemp, wool, silk, polyester, nylon, acrylic, vinylon, polyolefin, and rayon are preferred. Such textile yarns for clothing are suitable for various types of clothing. Organic fiber yarns also include any yarns such as spun yarns, twisted yarns, monofilament yarns, multifilament yarns, and the like. In the present invention, paper threads and existing conductive threads (silver-deposited threads or conductive material-kneaded threads) are available as threads that can be twisted with tungsten.

It is preferable that the fabric is a woven fabric, the metal filaments are spaced between the warp and the weft, and at least part of the intersections of the warp and the weft are soldered. This pattern is suitable for clothing that heats metal filaments.

The metal filament is preferably at least one filament selected from tungsten (W), molybdenum (Mo), copper (Cu) and stainless steel (SUS). Tungsten (W) is used in the light-emitting parts of incandescent lamps and discharge lamps. The melting point is 3380° C., but the filament has a lower melting point due to the small amount of doping involved. Molybdenum (Mo) has a melting point of 1620°C. A stainless steel (SUS) wire is said to be usable at an annealing temperature of 1150° C. or less, and for example, a stainless steel wire with a diameter of 11 μm is sold by Nippon Seisen Co., Ltd. Copper is the most commonly used wire. The wire diameter of the metal filament can be arbitrary. As an example, 100 μm or less is preferable. In the case of wires of metal filaments for heating clothing, the diameter is preferably 30 to 100 μm. In the case of a detection wire used in a wearable clothing fabric for measuring blood pressure, pulse, etc., the diameter is preferably 22 μm or less, more preferably 5 to 22 μm, still more preferably 5 to 15 μm, particularly preferably 8 to 12 μm. is. If it is the said diameter, even if it touches skin, it will be hard to feel rough feeling. In addition, when the organic fiber yarn is covered and/or twisted, the metal filaments are thin and difficult to see, and do not interfere with the dyeability and color of the organic fiber yarn. The metal filaments may be monofilaments or multifilaments, but monofilaments are easier to handle. The use of filaments (long fiber yarns) allows electrical continuity at any portion of the fiber structure, including both ends.

The solder metal is preferably solder containing Sn--Zn as a main component or solder containing Pb--Sn as a main component. These solder metals are suitable for ultrasonic soldering and can solder metal filaments directly without the need for flux. Solder containing Sn--Zn as a main component is available, for example, from Kuroda Techno Co., Ltd. under the trade name of "CELLSOLZA", and solder containing Pb--Sn as a main component under the trade name of "CELLSOLZER ECO" manufactured by Kuroda Techno Co., Ltd., for example.

The fabric containing a soldering part of the present invention is suitable for a heat generating fabric by electrical resistance, a fabric for wearable clothing, or a fabric for detecting a short circuit between metal filaments. Fabrics that generate heat by electrical resistance are used, for example, in clothes worn by motorcyclists and in cold regions and high mountains. The short-circuit detection cloth is, for example, a bodily fluid leakage detection cloth of a human body.

The thread containing the metal filament is composed of a core thread, a flower thread and a presser thread, the flower thread is a twisted thread having a loop or slack, and at least one thread selected from the core thread, the flower thread and the presser thread is The yarn is a yarn in which organic fibers are covered by metal filaments, and it is preferable that the whole yarn is real-twisted. Such a twisted yarn is also called a design twisted yarn, and since it has elongation even if it contains a metal filament yarn, it can be processed into a woven fabric or a knitted fabric. A water-soluble fiber yarn may be used as part of the design twisted yarn. Water-soluble fiber yarns include, for example, water-soluble vinylon, which can be dissolved in hot or boiling water.

A covering yarn in which a water-soluble fiber thread is wound around the surface of a metal filament can also be used. This covering yarn is straight as a whole. This is because the shape of the metal filament remains. The water-soluble vinylon may be filament yarn or spun yarn. The covering yarn is preferably a single covering yarn or a double covering yarn. Among these, the single covering yarn is preferable because it is easy to manufacture and the cost is low. It is preferable that the metal filament of the core thread is further provided with a water-soluble fiber thread as a sprinkling thread. By arranging such an attachment thread, the integrity between the metal filament and the covering thread is enhanced.

The covering yarn and twisted yarn can be produced using a twister such as a ring twister, a double twister, a tri twister. In particular, a ring twister and a double twister can apply tension and mass production is possible, which is preferable in terms of cost.

Yarns comprising metallic filaments and organic fibers may be knit-denit yarns. This knit-denit yarn is a knit-denit yarn obtained by knitting a metal wire-containing yarn and unknitting the knitted fabric. When the knit is unknitted, the crimped configuration of the knit remains in the yarn. Elasticity is exhibited by this crimp. The rate of change in apparent length of the metal wire-containing knit denit yarn between 0 (zero) g and 30 g load is preferably 2 times or more, more preferably 3 times or more. If it is within the above range, it can also be applied to elastic fabrics. The stretch elastic modulus defined in JIS L 1013:2010, "8.11 Elasticity" A method is preferably 50% or more, more preferably 65% or more, and still more preferably 80% or more. If it is within the above range, it can also be applied to elastic fabrics.

An example of the advantages of the present invention is as follows.
(1) Since it contains metal wires, it does not peel off and is excellent in washability.
(2) It is more resistant to abrasion than threads containing conductive materials such as carbon black.
(3) In the case of thin metal wires, they are almost invisible, so they are less likely to interfere with the color of the threads that are formed together.
(4) Even if the thin metal wire breaks, it does not easily stick to the skin, and its fineness makes it comfortable to the touch.
(5) Static electricity can be removed by combining with static electricity-prone fibers. This is useful for antistatic clothing, work clothing, firefighting clothing, acrylic sweaters, and the like.
(6) Since it has stretchability, it is less tightened as an electrode in contact with the human body during exercise, and has good followability to the skin surface.
(7) It functions as a conductive wire or as a heating wire that generates heat when supplied with power. When combined with copper wire, which has good electrical conductivity, it is possible to heat only the necessary parts.
(8) Wearable clothing uses metal cords, metal plates, and metal snap buttons for the connection surface with power supply and measuring equipment, but there are problems such as limitations on the shape of the connecting device and the hardness of the connection surface. However, if the covering yarn of the present invention, especially the metal loop yarn in which the dissolving yarn is dissolved, is used, the connecting surface becomes like a hook-and-loop fastener that conducts electricity, which is effective in solving the above problem.
