In an embodiment of the present disclosure, the at least one conductive wire 120 is selected from signaling yarn and enameled wire, and the present disclosure is not limited thereto.
In the embodiment of the present disclosure, enameled wire comprises insulating paint. A material of the insulating paint is selected from polytetrafluoroethylene (PTFE, i.e. Teflon®), ethylene tetrafluoroethylene (ETFE), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyethylene (PE) and other polymer insulation materials, and the present disclosure is not limited thereto.

Optionally, the strength resistance of the conductive wire 120 can be increase by choosing the strength of the staple fiber 121 and/or an aspect ratio of a cross section of the sheet conductor 122 corresponding to the spiral extending manner. In the embodiment, the strength of the staple fiber 121 is 30 strands and the aspect ratio of the cross section of the sheet conductor 122 corresponding to the spiral extending manner is about 20, but the present disclosure is not limited thereto. For example, the strength of the staple fiber 121 is 26, 28 or 40 strands, or the aspect ratio of the cross section of the sheet conductor 122 corresponding to the spiral extending manner is about between 10 and 30 approximately.
In the embodiment, a material of the staple fiber 121 is selected from polyester, polyarnide, polyacrylonitrile, polyethylene, polypropylene, cellulose, protein, elastic fiber, poly perfluoroethylene, polyparaphenylene benzoxazole, polyether ketone, carbon and glass fiber, and the present disclosure is not limited thereto. The material of the staple fiber 121 can be selected according to requirements.
In the embodiment, a material of the sheet conductor 122 is alloy, such as copper-nickel alloy, copper-tin alloy, copper-nickel-silicon alloy, copper-nickel-zinc alloy, copper-nickel-tin alloy, copper-chromium alloy, copper-silver alloy, nickel-brass alloy, phosphor bronze alloy, beryllium copper alloy, nickel-chromium alloy, copper-tungsten alloy, stainless steel and other commercially conductive alloys, but the present disclosure is not limited thereto. In different applications, the material of the alloy can be different. For example, the conductive wire 120 can be touch sensor element of touch control textile, one end of the conductive wire 120 is used to receive a scan signal and the other one end of the conductive wire 120 is used to transmit a touch sensing signal. Therefore, the alloy with a smaller resistance value can be selected as the material of the sheet conductor 122.

In the embodiment, a material of the insulating layer 123 is selected from polytetrafluoroethylene (PTFE, i.e. Teflon®), ethylene tetrafluoroethylene (ETFE), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polyethylene (PE) and other polymer insulation materials, and the present disclosure is not limited thereto. The material of the sheet conductor 122 and the insulating layer 123 can be selected according to the actual demand. For example, the conductive wire 120′ can be used as a heating element for heating textile, so the sheet conductor 122 can be made of an alloy with a large resistance value, and the insulating layer 123 can be made of an insulating material with high heat resistance (for example, polytetrafluoroethylene).

In summary, because the conductive wire 120 of the present disclosure is disposed with the elastic textile 100 in the wavy manner, the conductive wire 120 can be stretched accompanying with elastic webbing 110 when the elastic webbing 110 is stretched, and thus the conductive wire 120 will not be broken by external forces. In addition, in the embodiment that the signaling yarn is provided as the conductive wire 120 of the present disclosure, the staple fiber 121 having strength between 26 and 40 strands functions as the support material, and the sheet conductor 122 is enlacing the surrounding surface of the staple fiber to increase the strength resistance of conductive wire 120. Therefore, the conductive wire 120 of the present disclosure has a better stretch elasticity and strength resistance.
