High-electromagnetic-shielding multilayer silver fiber fabric

Abstract

The invention discloses a high-electromagnetic-shielding multilayer silver fiber fabric. The high-electromagnetic-shielding multilayer silver fiber fabric comprises surface layers and a lining layer, a silver fiber texture layer having a spatial three-dimensional slot type structure, used for the electromagnetic shielding and connecting the surface layer with the lining layer is arranged between each of the surface layer and the lining layer, the silver fiber texture layer is uniformly distributed in each of the transverse rows of a healthy fabric, and the silver fiber between adjacent two transverse rows forms the spatial three-dimensional slot type structure through hot compression and fixation to realize close contact. The silver fiber texture layer is used as the connecting layer for connecting each of the two surfaces with the lining layer, and the surface layers and the lining layer are used to cover, so the fabric is beautiful, the solarization possibility of oxidized silver-plated fibers is reduced, and the silver layer of the silver-plated fibers is protected; and the connecting layer forms the spatial three-dimensional slot type structure, so the silver fibers in two adjacent transverse rows contact with each other to form a conductive circuit, so the electromagnetic shielding effect is substantially improved.

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.
