Fabric capable of shielding against electromagnetic waves and preparation method of fabric

Abstract

The invention discloses a fabric capable of shielding against electromagnetic waves. The fabric comprises a surface layer and a lining layer. The surface layer and the lining layer are fixedly connected with each other through a connecting layer, one end of the connecting layer is connected with the surface layer, the other end of the connecting layer is connected with the lining layer, the connecting layer is multiple Faraday cage layer bodies formed by weaving sliver fiber, the surface layer is formed by weaving blended yarn of regenerated cellulose fiber and the sliver fiber in the weight ratio of (1-5):1, and the lining layer is formed by weaving silver nylon multifilament. By means of the fabric, the shielding effect on the electromagnetic waves is strengthened, the shielding effect is excellent, and the fabric is convenient to clean, long in oxidation period, good in sense of touch and good in elasticity.

Description

technical field

[0001] this invention. Background technique

[0002] With the development of science and technology, our society has entered the electronic age. Various electronic appliances are widely used in military scientific research and industrial, agricultural, commercial and medical industries, and now they have entered thousands of households, promoting the progress of human material civilization. , At the same time, they have caused a certain amount of electromagnetic wave pollution to the environment, which has become a major social nuisance. Most of the existing fabrics for shielding electromagnetic waves are single-layer fabrics woven from silver-plated fabrics. The oxidation cycle of silver-plated fabrics is short, and oil stains will accelerate oxidation. The color is single and easy to change color after oxidation; there are also double-layer shielding fabrics on the market. For the electromagnetic wave fabric, the surface layer and the inner layer are conne...
