(100) is formed.

Here, the warp yarn 10 is an elastic material that can be stretched, and a rubber material having excellent elasticity is pulled as thin as a thread. The warp yarn 10 may generally include various types of rubber bands, and may include spandex or latex to maximize elasticity.

1 illustrates an example in which six warp yarns are implemented, but the number of warp yarns is not limited thereto. However, it is preferable that the warp yarn is implemented with at least 3 strands or more.

On the other hand, the weft yarn 20 includes a conductive yarn (A) and a non-conductive yarn (B) for the bar.

The conductive thread (A) is a conductor capable of electrical connection, and may be implemented as a metal thread made of at least one strand.

The metal thread may be implemented with various types of conductors such as gold, silver, copper, and copper having excellent electrical connection. However, it is preferable that the metal yarn of the present invention is manufactured by performing heat treatment on an alloy of copper and tin. For example, the conductive thread (A) may be manufactured by braiding 15 metal yarns subjected to heat treatment to an alloy of copper and tin having a thickness of 0.05 mm.

The non-conductive thread (B) for bar means a thread composed of general fibers that can be barbed in a covering and the like, and may be implemented with various types of threads including spun yarn and filament yarn.

After the number of conductive yarns (A) are continuously weaved side by side, a predetermined number of non-conductive yarns (B) for a bar are continuously weaved side by side and may be repeatedly weaved.

In the example shown in Fig. 2, the elastic wire 100' is woven so that 8 conductive threads are arranged side by side on each warp thread 10, and 6 non-conductive threads for a bar are woven so that they are arranged side by side. It can be configured in the form

In particular, the weft yarn 20 has a zigzag pattern as shown in FIG. 2 in which a preset number of non-conductive yarns B for a bar continuously interwoven with the warp yarn 10 connect each warp yarn 10 . It may be woven.

In this way, as shown in FIG. 2 , a zigzag pattern may appear repeatedly while a plurality of non-conductive yarns B for a bar are repeatedly woven at different positions for each warp yarn 10 . Accordingly, the elastic wire 100' can be more stably fixed to the covering by sealing the elastic wire 100' to the covering in a zigzag pattern.
