Description

  The present invention relates to a conductive fabric and a metal fabric that can be used as an excellent electromagnetic shielding material, and in particular, a conductive fabric capable of greatly improving electromagnetic shielding performance and a metal fabric that can be easily made. It is about.

  In recent years, IT devices and OA devices such as personal computers have rapidly spread due to the development of IT (information technology), and are radiated from these IT devices and OA devices in normal home and work environments. The effect of electromagnetic waves on the human body has become a problem. Therefore, in the device described in Patent Document 1, for the purpose of application to the electromagnetic wave shielding cabinet or the like of the above devices, a woven fabric composed of a composite elastic yarn in which metal fibers are spirally wound around an elastic fiber. Has proposed a synthetic resin plate for shielding electromagnetic waves, in which is sandwiched between thermoplastic synthetic resin sheets.

Here, “ordinary spinnable fiber” includes cotton, silk, hemp, wool, nylon, vinylon, polyester fiber, acrylic fiber, vinylidene chloride fiber, organic fiber such as acetate and rayon, and inorganic fiber such as glass fiber. Alternatively, these fibers can be mixed. As a result, the metal wire is twisted around the usual spinnable fiber of the required thickness, so it has high stretchability, and the mixed yarn formed even if the metal wire is thickened has sufficient strength and flexibility. Therefore, it can be easily made into a woven fabric with a normal loom.

Here, “ordinary spinnable fiber” includes cotton, silk, hemp, wool, nylon, vinylon, polyester fiber, acrylic fiber, vinylidene chloride fiber, organic fiber such as acetate and rayon, and inorganic fiber such as glass fiber.

  In order to obtain a conductive fabric having stretchability, it is not successful to simply replace a normal spinnable fiber disposed at the center of the mixed yarn with a stretchable fiber. Therefore, as a result of the inventor's earnest experiment research, the inventor has formed a Z-twisted and / or S-twisted stretchable fiber disposed at the center and at least one conductive metal wire. It has been found that by providing a gap with the metal wire portion, remarkable stretchability can be obtained in the woven conductive fabric, and the present invention has been completed based on this finding.

Since a gap is formed between the metal wire portion and the conductive wire, a conductive fabric having remarkable stretchability can be obtained. Although depending on the use of the conductive fabric, the metal wire is immersed in water, and therefore, a rust-resistant material such as a stainless wire, an aluminum wire, or a zinc wire is more preferable.

  In this way, by increasing the ratio of the area of the conductive metal wire exposed on the surface as much as possible, while having a larger electromagnetic shielding performance, it can be woven with a loom just like a normal woven fabric and stretched It becomes the conductive textile which also has property.

Can do. Therefore, in addition to the operational effects of the third and fourth aspects of the invention, there is no need to immerse in water, so that the number of man-hours can be saved, and the operational effect of not selecting a material as the metal wire can be obtained.

  In this way, by increasing the ratio of the area of the conductive metal wire exposed on the surface as much as possible, while having a larger electromagnetic shielding performance, it can be woven with a loom just like a normal woven fabric and stretched It becomes the conductive textile which also has property.

  That is, when the thickness of the conductive metal wire is less than about 50 μm, the possibility of breaking when forming a mixed yarn by twisting Z and / or S on a normal spinnable fiber is increased, Since the ratio of the conductive metal wire exposed on the surface when made into a woven fabric is small, a large electromagnetic shielding performance cannot be obtained. On the other hand, when the thickness of the conductive metal wire exceeds about 500 μm, the mixed yarn is spun well due to lack of flexibility when forming a mixed yarn by Z-twisting and / or S-twisting ordinary spinning fiber. Can not do it. Therefore, by setting the thickness of the conductive metal wire within the range of about 50 μm to about 500 μm, the mixed yarn can be easily spun, and the conductive metal wire exposed on the surface when made into a conductive fabric. Therefore, a large electromagnetic shielding performance can be obtained.

It can be manufactured and can be applied to products formed from thin metal wires such as electromagnetic shielding materials and metal filters. The fineness of the metal woven fabric and the thickness of the metal wire can be arbitrarily adjusted by appropriately selecting the thickness of the water-soluble fiber and the thickness of the metal wire when forming the mixed yarn.

  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. Thus, the nickel-plated copper wire 4 is twisted around the nylon fiber 3 having a necessary thickness, so that it has high stretchability, and the nylon fiber 3 is formed even if it is covered with the nickel-plated copper wire 4 as much as possible. Since the mixed yarn 2 has sufficient strength and flexibility, it can be easily made into a woven fabric by a normal loom.

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 a result, the nickel-plated copper wire 4 is twisted around the nylon fiber 3 having a thickness that is necessary for shielding electromagnetic waves, so that the nickel-plated copper wire 4 is highly stretchable. However, since the formed mixed yarn 7 has sufficient strength and flexibility, it can be easily made into a woven fabric by an ordinary 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. Therefore, it can be applied to electromagnetic shielding curtains, electromagnetic shielding sheets, and electromagnetic shielding work clothes in which conductive fabric is sewn only on the front surface of an apron-type garment that does not care about the feel of metal.

The water-soluble vinylon fiber 13 is formed by Z-twisting (14a) and S-twisting (14b) of a stainless steel wire 14 as a metal wire. As a result, the stainless steel wire 14 is twisted around the water-soluble vinylon fiber 13 having a necessary thickness, so that it has excellent stretchability, and the formed mixed yarn 12 has sufficient strength and flexibility. It can be made into a woven fabric by a normal loom. The mixed yarn 12 thus formed was woven with a loom to produce a mixed yarn fabric 10 as shown in FIG.

  The mixed yarn fabric 10 is immersed in warm water of about 60 ° C. and sufficiently shaken so that the warm water reaches the inside of the mixed yarn fabric 10.
