Anti-radiation fiber based on nano material and preparation method thereof

Abstract

The invention relates to the technical field of anti-radiation textile materials, in particular to an anti-radiation fiber based on a nano material and a preparation method thereof. The anti-radiationfiber comprises the following components of, in percentage by weight, 3.5%-48.5% of activated carbon resin loaded with nano zinc oxide, 0.1%-1.5% of yttrium-doped zinc ferrite, and the balance of polyester chips, wherein the nano zinc oxide is prepared by taking dihydromyricetin as a template, and the weight ratio of the nano zinc oxide to the yttrium-doped zinc ferrite is 1: (25-30). The fiber has excellent mechanical strength, anti-radiation performance, anti-ultraviolet permeability and the effect of inhibiting virus bacteria, meanwhile, the washing resistance and light aging resistance ofthe fiber are excellent, and the service life of a fiber product is prolonged while the quality of the fiber product is improved.

Description

technical field [0001] The invention relates to the technical field of anti-radiation textile materials, in particular to a nano-material-based anti-radiation fiber and a preparation method thereof. Background technique [0002] With the rapid development of modern science and technology, an invisible and intangible source of pollution has attracted increasing attention from all walks of life, which is electromagnetic radiation known as the "invisible killer". For the human body, a good conductor, electromagnetic waves will inevitably pose a certain degree of harm. Generally speaking, radar systems, television and radio transmission systems, radio frequency and microwave medical equipment, communication transmission stations and ultra-high voltage power lines, and most household appliances can produce electromagnetic radiation sources of various forms, frequencies, and intensities. Nowadays, electromagnetic radiation pollution is recognized as an important pollution source ...

Professional sun protection clothing can protect against ultraviolet rays and radiation, but it is usually expensive and not suitable for the general population

The low-priced sun protection clothing has poor UV effect, and even the sun protection effect is not much different from that of ordinary clothing

[0004] Radiation-proof fibers in the prior art have been disclosed, such as the Chinese invention patent whose authorization notification number is CN106381684B, which discloses a method for preparing a multi-layer radiation-proof fiber based on ferrite and nanomaterials, comprising the following steps: Add high-molecular-weight polyethylene into the solvent, stir until completely dissolved, then add nano-silicon carbide powder and amphoteric surfactant, mix well, slowly evaporate to viscous, mechanically draw, and heat dry to form inner fiber; The inner fiber is immersed in the polypyrrole liquid, shaken, taken out, and dried to obtain the middle layer fiber; the ferrite-containing gel is added to the silk protein aqueous solution, and a cationic surfactant is added, stirred and concentrated to form a viscous liquid, and the middle layer The surface of the fiber is coated with a viscous liquid, dried, recoated, and dried to form a product. However, the high content of ferrite will inevitably affect the smoothness of the fiber, and its ferrite can be coated, dried, and recoated. The way of covering and re-drying is attached to the surface of the fiber, and its fastness is not enough, which will inevitably lead to poor washing fastness, and the radiation protection performance will decline in the later stage of multi-washing.
