A silver fiber multi-layer fabric with high electromagnetic shielding

Abstract

The invention discloses a silver fiber multilayer fabric with high electromagnetic shielding, which includes a surface layer and an inner layer, and a silver fiber structure with a space three-dimensional groove structure for connecting the surface layer and the inner layer for electromagnetic shielding is arranged between the surface layer and the inner layer layer, the silver fiber tissue layer is evenly distributed in each row of the healthy cloth, and the silver fibers between two adjacent rows are in close contact with each other due to the formation of a three-dimensional groove structure in space by hot pressing. The silver fiber tissue layer is used as the connecting layer connecting the two surface layers and the inner layer, and the covering of the surface layer and the inner layer makes the fabric more beautiful, reduces the possibility of the oxidized silver-plated fiber being exposed to the sun, and protects the silver of the silver-plated fiber. The layer is not damaged, and the connection layer forms a three-dimensional groove structure in space, so that two adjacent horizontal silver fibers contact each other, forming a conductive loop, which greatly improves the electromagnetic shielding effect.

Description

technical field [0001] The invention belongs to the technical field of textile product structure, and in particular relates to a silver fiber (filament, the same below) multi-layer fabric with high electromagnetic shielding. Background technique [0002] Existing anti-radiation fabrics are generally double-layer or triple-layer fabrics composed of conventional yarn braids and silver-plated filament braids. CN201849030U discloses a kind of anti-electromagnetic radiation woven fabric of silver-plated fiber. Due to the double-layer structure design, the fabric has a double-sided effect. One side is mainly woven by conventional yarn, and the other side is mainly woven by silver-plated fiber. connected by a small number of interweaving points. But these structures inevitably make the silver-plated fiber layer exposed on the outer layer or the inner layer. CN202559029U then discloses a kind of weft plain stitch silver fiber antibacterial fabric, has double-sided effect fabric ow...

But these structures inevitably make the silver-plated fiber layer exposed on the outer layer, or the inner layer

CN202559029U then discloses a kind of weft plain stitch silver fiber antibacterial fabric, has double-sided effect fabric owing to adopting plaiting structure, one side shows as conventional yarn, and the other side shows silver-plated fiber, as figure 1 As stated, it is impossible to cover the silver-plated fiber layer between the inner layer and the outer layer

Because the silver-plated fiber is dark gray, it not only affects the beauty of the fabric, but also affects the durability of the electromagnetic shielding of the fabric

On the one hand, due to the exposure of the silver-plated fiber layer and the effects of long-term sun oxidation and wear, the silver layer on the surface of the silver-plated fiber will turn yellow, which will affect the appearance of wearing.

On the other hand, once the silver-plated fiber layer is in close contact with the skin, it will be affected by abrasion or sweat, which will cause the silver layer to fall off or turn yellow, thereby reducing the shielding performance.
