Weaving process for anti-electromagnetic-radiation air layer weft knitted fabric

Abstract

The invention discloses a weaving process for anti-electromagnetic-radiation air layer weft knitted fabric. The front and back surfaces of the knitted fabric are weaved through a weaving machine by using cotton or cotton-polyester blended fabric as raw materials. Tissue of the fabric is produced by a double-sided dobby air layer structure. The stainless steel filaments are weaved in a doubling manner into the knitted fabric. The stainless steel filaments are formed on the front surface of the fabric in a manner of locally forming a ring. Float length between adjacent stainless steel filamentsis in the air layer structure. The invention has the advantages of high electromagnetic shielding efficiency, strong performance of anti-electromagnetic-radiation, soft feel, wrinkle-free property and launderability.

Description

technical field [0001] The invention relates to a weaving process of anti-electromagnetic radiation air layer weft-knitted fabric. Background technique [0002] At present, there are four main raw materials for the production of anti-electromagnetic radiation fabrics at home and abroad. Metal filaments, blended yarns of metal staple fibers and other natural or chemical staple fibers, electroplated metal coating on the surface of chemical fiber filaments, and conductive polymer filaments. Among them, metal filaments have better electromagnetic shielding performance when used in fabrics, but the disadvantages are that the fabric feels hard, the fabric is easy to wrinkle, and the wrinkles are not easy to recover. The metal staple fiber blended yarn feels softer, but because of the unreliable connectivity of the metal fibers in the yarn (it has a greater relationship with the mixing ratio of the metal fibers), its anti-electromagnetic radiation performance is poorer. The elect...

Problems solved by technology

However, in the process of adding nano-silver to the fiber substrate, there are problems such as the agglomeration of nanoparticles, pollution and the influence of nanoparticles on the performance of the main fiber.

Since the silver particles are dispersed inside and outside the fiber, only a small part directly contacts the skin, unlike the surface of the silver-plated fiber surrounded by a layer of pure silver, so it cannot fully reflect the good antibacterial, deodorizing, electromagnetic shielding and other functions of silver. feature

In addition, this kind of fiber is expensive, and it is still difficult to use it widely at present.

[0003] From the perspective of fabric structure, anti-electromagnetic radiation fabrics currently use more woven fabrics, and their fabrics are mostly used for protective work clothes, but the garments produced from woven fabrics are not suitable for the production of close-fitting garments due to their own characteristics. The neutral position is likely to cause electromagnetic radiation leakage, and the protective effect of the clothing is quite different from the laboratory test results of the fabric.

There is no metal wire anti-electromagnetic radiation fabric with knitted structure at present

[0004] In addition, plants are treated with anti-electromagnetic radiation by metal coating the fabric. This kind of fabric has excellent anti-electromagnetic radiation performance, but it is not as resistant to washing as the fabric woven from filaments woven with metal-coated surfaces.
