The following patent documents 1 to 5 are documents found by searching from the viewpoint of finding as close as possible to the content of the present invention, but there is still a considerable distance from the present invention in terms of technical ideas and structures.
[0004] In addition, the related terms of "double-layer winding of foil, gold thread, and silver thread" were selected as keywords, and the "use of Z-winding multi-layer winding wire and S-winding multi-layer winding wire" related to the present invention was searched. Although there are scattered documents related to metal foil double-layer coiled wires for braiding combined wires or braiding sleeves", their application occasions are very different from the present invention, so they are not listed as patent documents.

Embodiment 1

[0138] The combined yarn 1 of Example 1 is "combined yarn (A) of the present invention", and the combined yarn 1 of Comparative Examples 1 to 3 is a combined yarn for comparison, and the combined yarns 1 are individually used for weaving.

Embodiment 2）

[0182] In Example 1 shown in Table 1, the constituent yarns of composite yarn 1 use "1 piece of Z-wrapped multi-layered yarn (2Z), 1 piece of S-wound multi-layered yarn (2S), 1 piece of Z-wound Single-layer winding wire (1Z), and one non-metallic wire (R) made of synthetic resin yarn, a total of 4 wires, as Example 2, only Z winding single-layer winding wire (1Z ) of the combined wire 1 case for braiding.

[0183] At this time, almost the same results as in Example 1 were obtained except that the resistance value in Table 2 was 37 mΩ and the sleeve weight in Table 2 was 48 g. From this, it can be seen that the method of embodiment 2 can also obtain better results close to the method of embodiment 1.

Embodiment 3）

[0185] In Example 1 shown in Table 1, the constituent yarns of composite yarn 1 use "1 piece of Z-wrapped multi-layered yarn (2Z), 1 piece of S-wound multi-layered yarn (2S), 1 piece of Z-wound A single-layer wound wire (1Z) and a non-metallic wire (R) made of synthetic resin yarns" total 4 wires, but Example 3 is for the use of "60 filaments, 0.25mm in diameter glass fiber multi-strand Wire" is woven as the case of wire 1 in which non-metallic wire (R) is combined.

[0186] At this time, except that the resistance value in Table 2 was 31 mΩ and the sleeve weight in Table 2 was 54 g, almost the same results as in Example 1 were obtained. From this, it can be known that the method of embodiment 3 can also obtain better results close to the method of embodiment 1.

Abstract

The objective of the present invention is to provide an electromagnetic shielding braided sleeve, and composite yarn for braiding the same, that not only has excellent electromagnetic shielding capability, but is light in weight, protects against twisting, minimizes bending, has good opening and broadening characteristics under external pressure from electrical wiring and the like, and furthermore has good fit with the object covered after application, resists end disintegration and generation of residual material during braiding, and despite excellent quality is also cost-effective. The composite yarn for braiding comprises a composite yarn (A) that is a parallel yarn including at least the following three components: a Z-wrapped multilayer wound yarn (2Z) having a configuration in which multiple layers of a narrow metal foil (F) are Z-wrapped around a core yarn (C), an S-wrapped multilayer wound yarn (2S) having a configuration in which multiple layers of a narrow metal foil (F) are S-wrapped around a core yarn (C), and a non-metallic yarn (R). Furthermore, the electromagnetic shielding braided sleeve comprises a sleeve-shaped braided body (B) of such composite yarn (A).

Description

technical field [0001] The present invention relates to a combined yarn for braiding (a bundle of bundled yarns necessary for braiding) constituted by using a specific metal foil winding yarn. Also, the present invention relates to an electromagnetic wave shielding braided sleeve using the combined braiding yarn. Background technique [0002] (Electromagnetic wave shielding braided sleeve) [0003] Many documents are known about an electromagnetic wave-shielding braided sleeve that braids a material made of a metal foil wound around a core wire. The following patent documents 1 to 5 are documents found by searching from the viewpoint of finding as close as possible to the content of the present invention, but there is still a considerable distance from the present invention in terms of technical ideas and structures. [0004] In addition, the related terms of "double-layer winding of foil, gold thread, and silver thread" were selected as keywords, and the "use of Z-winding...
