Problems solved by technology

It can be seen that at present, ferrite fibers need to be compounded with other materials and added to textiles to endow textiles with the function of preventing electromagnetic radiation. However, there are not many ferrite fibers with excellent wearability and anti-electromagnetic radiation performance.

Abstract

The invention provides a method for preparing multilayer radiation-resistant fibers based on ferrites and nanometer materials. The method comprises the following steps: adding ultrahigh molecular weight polyethylene into a solvent, and stirring until the ultrahigh molecular weight polyethylene is completely dissolved; adding silicon carbide nano powder and an ampholytic surfactant, uniformly mixing, slowly evaporating to be viscous, mechanically drawing, performing thermal drying, and forming inner-layer fibers; impregnating the inner-layer fibers in polypyrrole liquid, oscillating, taking out, and airing, thereby obtaining intermediate layer fibers; and adding gel containing ferrites into fibroin aqueous solution, adding a cationic surfactant, stirring and concentrating into viscous liquid, coating the surface of the intermediate layer fibers with the viscous liquid, drying, coating again and drying, thereby obtaining the product. The multilayer radiation-resistant fibers provided by the invention adopt a simple preparation method and are excellent in anti-electromagnetic performance and have good mechanical properties and high flexibility and serviceability.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a preparation method of a multi-layer anti-radiation fiber based on ferrite and nanometer materials. Background technique [0002] Electromagnetic radiation is a physical phenomenon in which energy is emitted from a source to space in the form of electromagnetic waves. Electromagnetic fields are distributed in every corner of people's living environment. There are natural electromagnetic fields: solar electromagnetic field, cosmic electromagnetic field, spark discharge in nature, etc., and artificial electromagnetic fields: Power lines, discharge tubes, automobiles, electrical equipment, electronic equipment, building metal components, etc. With the rapid development of modern science and technology, the scope and depth of electromagnetic radiation are also expanding. The emergence of electromagnetic radiation has brought great convenience to people's lives,...
