Description

Technical Field

[0001] The present invention belongs to the technical field of flexible high-elastic conductive wires, and more specifically, particularly relates to a method for making a skin-friendly and highly tensile-resistant elastic conductive wire that can be sewn. Background Art

[0002] Traditionally, smart wearable clothing uses elastic conductive threads woven from rubber bands, silver fiber threads, nylon and spandex threads.

[0003] In actual application, the market feedback shows that the wire has the following disadvantages when used in smart wearable clothing:

[0004] A large amount of sweat will accumulate on the smart wearable clothing. The conductor is a silver wire without a jacket, which causes the sweat to contact the silver wire and gradually corrode the silver wire, resulting in a short service life of the smart wearable clothing, which is very unfavorable for the use of the device.

[0005] Since the wire has no insulating protective layer, there is a safety hazard of leakage during actual use, which makes the device have a natural defect;

[0006] Currently, the conductive wires used in smart wearable clothing are made of traditional tinned copper wires with an insulating layer. In actual applications, such conductive wires have natural defects such as being unable to be sewn and being easily broken during use, which results in them being unable to be mass-produced and applied in the field of smart clothing.

[0007] Therefore, in view of this, the existing structure and defects are studied and improved, and a method for sewing a skin-friendly and highly tensile elastic conductive thread is provided, in order to achieve a more practical purpose. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a method for making a skin-friendly and highly tensile-resistant elastic conductive thread that can be sewn to solve the above problems.

[0009] A method for making a skin-friendly and highly tensile-resistant elastic conductive thread that can be sewn, comprising the following steps:

[0010] S1: Making a conductive core. The making of the conductive core is divided into two processes: the first process is making the inner layer of the conductive core, and the second process is making the conductive core;

[0011] S2: removing burrs from the surface of the conductive wire core and laminating the conductive wire core to produce a finished product;

[0012] S3: braided high elastic conductor;

[0013] S4: making a fabric wrap;

[0014] S5: Wrap the highly elastic wire and press it into a flat shape during the weaving process to obtain an elastic conductive wire.

[0015] Preferably, in the first process of making the conductive core described in S1, the specific method is as follows: use a stretcher to straighten the silver fiber wire and place it in the middle of the capstan outlet, then pull the polyaromatic fiber out of the capstan outlet, wrap the silver fiber wire with a 30-degree spiral, and twist out the inner layer of the conductive core. In the second process of making the conductive core described in S1, the specific method is as follows: use a stretcher to place the inner layer of the conductive core in the middle of the capstan outlet, then pull the tinned copper wire out of the capstan outlet, wrap the inner layer of the conductive core with a 30-degree spiral, and twist out the conductive core. In S2, remove burrs from the surface of the conductive core, and coat the conductive core to produce a finished product. The specific method is as follows: use high-temperature pressing to remove burrs on the surface of the conductive core, melt Teflon at high temperature into a viscous solid, and then pass the conductive core through a wire puller through the Teflon viscous coating, adjust the outer diameter of the Teflon coating layer by adjusting the outlet aperture of the wire puller, and then cool the wire by water cooling, and roll up the conductive core through a wire reel to produce a finished product.

[0016] Preferably, the braided high-elastic conductor described in S3 is specifically manufactured by the following method: 4 strands of rubber bands are centered, and the conductive core is spirally coiled on the rubber band at an angle of 30 degrees, and two strands of the first spandex stretch yarn are added on each side of the rubber band as warp yarns, and 64 strands of the second spandex stretch yarns are used as weft yarns. The warp yarns and weft yarns are interwoven by a shuttleless weaving machine, and the rubber band and the conductive core are wrapped in the center to weave a high-elastic conductor. The specific method for making the fabric wrapping layer described in S4 is as follows: the high-elastic conductor is set with the weft yarn centered, and 64 strands of high-elastic nylon yarn are used as the warp yarns. A shuttleless weaving machine is used to interweave the warp and weft yarns, and the high-elastic conductor is wrapped therein.

[0017] Preferably, in S5, the highly elastic wire is wrapped, and the wire is flattened during the weaving process to obtain the elastic conductive wire. The specific method is as follows: in the process of wrapping the highly elastic wire using a shuttleless weaving machine, the wire is flattened to obtain the elastic conductive wire, and smart clothing is sewn on the outside of the elastic conductive wire. The smart clothing is provided with smart devices and functional modules. Both ends of the elastic conductive wire can be unsealed to obtain the wire core and the Teflon can be stripped off and terminals can be installed. The terminals of the elastic conductive wire can be connected to the smart device and the functional module.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, by using high-elastic nylon yarn as the conductive wire core material, the resistance of the wire is reduced, the conductivity of the wire is improved, the output efficiency of the functional module is improved, and the accuracy of the intelligent device in collecting human body detection signals is improved.

[0020] In the present invention, by using silver fiber conductor as the conductive wire core material, the rigidity defect of tinned copper wire is solved, the flexibility of the conductor is increased, and the risk of wire breakage caused by insufficient flexibility of the wire during the use and cleaning of smart clothing is solved, thereby ensuring the service life of the wire.

[0021] In the present invention, by wrapping the wire core with Teflon, the defect of sweat corroding the wire during the use of smart clothing is solved. The insulation of the Teflon material also solves the leakage problem of the wire during use, which greatly improves the safety of the use of smart clothing.

[0022] In the present invention, the elasticity of the wire is ensured by weaving the rubber band, the second spandex elastic yarn and the first spandex elastic yarn. The wire has flexibility and elasticity and can be perfectly used as a connection medium in a smart wearable device.

[0023] In the present invention, polyaromatic fibers are added to the conductive wire core, thereby improving the overall tensile strength of the wire and making the wire durable in various complex application environments.

[0024] In the present invention, a layer of flat fabric is woven outside the high-elastic wire, and the flat two sides enable the wire to be sewn on the wearable clothing, thereby solving the problem of sewing the wire.

[0025] In the present invention, the elastic conductive wire is used to be sewn into the inside of wearable clothing and directly contact the human skin, while the fabric layer outside the elastic conductive wire solves the wearing sensation problem of the wearable device contacting the human skin. The fabric wrapping layer eliminates the problem of the wire pinching the skin. The outer woven material is a second spandex elastic yarn, which will not cause skin allergies.
