Problems solved by technology

[0009] Although the flexibility of metal fibers is similar to that of textile fibers, it is still difficult to spin high-count yarns above 9.84tex (60 lbs) due to their high relative density, strong rigidity, poor elasticity, large friction coefficient, and small cohesion force.

Abstract

The invention discloses an electromagnetic radiation shielding fiber. The base material of the fiber contains electromagnetic radiation absorption nano-powder, wherein the electromagnetic radiation absorption nano-powder comprises 40-50 parts by weight of nanometer iron oxide, 20-30 parts by weight of nanometer silica and 5-8 parts by weight of nanometer iron powder; and the weight ratio of the fiber base material to the electromagnetic radiation absorption nano-powder is 100:3-15. The electromagnetic radiation shielding fiber is synthesized through a master batch process in the invention, so the electromagnetic radiation shielding fiber has the advantages of substantial radiation shielding effect, simple processing route, easy operation, low cost, easy industrialized production, firm combination with fiber tissues, strong durability, and non-toxicity and safety.

Description

technical field [0001] The invention relates to an electromagnetic radiation shielding fiber and a manufacturing method of the electromagnetic radiation shielding fiber. Background technique [0002] The human body is exposed to electromagnetic wave radiation environment for a long time, which will seriously damage the physical and mental health and affect the normal life order. Studies have proved that the mechanism of electromagnetic wave radiation harming the human body is mainly thermal effect, non-thermal effect and cumulative effect. [0003] The thermogenic effect is the "heating" effect of high-frequency electromagnetic waves on the cells of the biological body. After the organism receives radiation, the polar molecules in the body undergo rapid alignment and movement with the change of the polarity of the electromagnetic field, and the molecules collide and rub against each other to generate huge heat. If the body temperature cannot be dissipated, the body heats up...
