  Embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1
First, Embodiment 1 of the present invention will be described with reference to FIG. FIG. 1A is an enlarged view showing the configuration of a mixed yarn constituting the conductive fabric according to the first embodiment of the present invention, and FIG. 1B shows the overall configuration of the conductive fabric according to the first embodiment of the present invention. It is a perspective view shown. FIG. 5 is a photograph 1 showing the state of the yarn for producing the conductive fabric according to the first embodiment of the present invention, and FIG. 6 shows an embodiment of the conductive fabric according to the first embodiment of the present invention. FIG. 7 is a view as a photograph 2, and FIG. 7 is a view as a photograph 3, showing an embodiment of the conductive fabric according to the first embodiment of the present invention.

As shown in FIG. 1 (a), the mixed yarn 2 constituting the conductive fabric 1 of Embodiment 1 is centered on a bundle 3 of nylon fibers as a plurality of ordinary spinnable fibers. The nylon fiber 3 is formed by Z-twisting (4a) and S-twisting (4b) a nickel-plated copper wire 4 as a conductive metal wire. The thickness of the nickel-plated copper wire 4 is about 80 μm. As a result, the nickel-plated copper wire 4 is twisted so as to be exposed on the surface of the nylon fiber 3 having a necessary thickness, so that the nylon fiber 3 is made of a nickel-plated copper wire as much as possible. Since the mixed yarn 2 formed even if covered with 4 has sufficient strength and flexibility, it can be easily made into a woven fabric by a normal loom.

  The mixed yarn 2 thus formed was woven with a loom to produce a conductive fabric 1 as shown in FIG. As shown in an enlarged view in FIG. 1 (b), the nickel-plated copper wire 4 is exposed at a considerable rate on the surface of the conductive fabric 1. Therefore, it is expected that the electromagnetic wave shielding performance is also great. Therefore, when the electromagnetic shielding performance of the conductive fabric 1 was measured, it showed a high value of 65 dB to 70 dB at a frequency of 100 MHz. In addition, since this conductive fabric 1 is thin, it can be applied to an electromagnetic wave shielding curtain, electromagnetic wave shielding work clothes, etc. even if it is doubled. The electromagnetic wave shielding performance was as large as 140 dB at 100 MHz.

  As described above, the conductive fabric 1 according to the present embodiment has a higher electromagnetic wave shielding performance by increasing the area ratio of the nickel-plated copper wire 4 as the conductive metal wire exposed on the surface as much as possible. However, it can be woven with a loom just like a normal woven fabric. Therefore, the present invention can be applied to electromagnetic wave shielding curtains, electromagnetic wave shielding sheets, electromagnetic wave shielding work clothes in which the conductive fabric 1 is sewn only on the front surface of an apron-type garment that does not care about the feel of metal.

  Photo 2 and Photo 3 are implementations corresponding to FIG. 1, and the pitch of the Z twist (4a) and the S twist (4b) is relatively coarse as shown in Photo 1. Therefore, it is estimated that the characteristic as an electromagnetic wave shielding material changes greatly only by changing the pitch of the Z twist (4a) and the S twist (4b).

  In addition, since the conductive fabric 1 manufactured in this way is excellent in flexibility, it is cut into a tape shape (bandage shape), wound around the portion to be shielded against electromagnetic waves or the whole, and the nylon fiber 3 portion is melted and melted. By solidifying and stopping, portions or the whole of various shapes can be easily shielded from electromagnetic waves.

Then, three nylon-plated copper wires 4 as conductive metal wires are respectively Z-twisted (4a) and S-twisted (4b) on the nylon fibers 3, and most of the nylon fibers 3 are used as conductive metal wires. It is formed so as to be covered with a nickel-plated copper wire 4. The thickness of the nickel-plated copper wire 4 is about 80 μm as in the first embodiment. As a result, the nickel-plated copper wire 4 is twisted so as to be exposed on the surface of the nylon fiber 3 having a thickness that is necessary for shielding electromagnetic waves, so that it is highly stretchable. Since the mixed yarn 7 formed even if covered with the nickel-plated copper wire 4 has sufficient strength and flexibility, it can be easily made into a woven fabric with a normal loom.

  As shown in FIG. 2 (b), the conductive fabric 6 of the present embodiment 2 woven with this mixed yarn 7 has the nylon fiber 3 arranged at the center of the mixed yarn 7, and most of it is nickel-plated copper. Since three nickel-plated copper wires 4 are Z-twisted (4a) and S-twisted (4b) around each so as to be covered with the wire 4, the surface of the woven fabric 6 is almost Only the nickel-plated copper wire 4 is exposed, so that the conductive fabric is further excellent in electromagnetic wave shielding.
