Novel mask based on geobacillus protein fibers

Abstract

The invention discloses a novel mask based on geobacillus protein fibers. The novel mask comprises an inner electrode layer, a geobacillus fibroin fiber layer, an outer electrode layer, a middle non-woven layer and a silver fiber layer which are arranged between an inner non-woven layer and an outer non-woven layer. The outer edges of the outer non-woven layer and the inner non-woven layer are provided with metal strips and connected with tensioning belts. The inner non-woven layer and the outer non-woven layer are used for isolating large-particle substances. And the surface of the outer non-woven layer is super-hydrophobic and super-oleophobic, so that external pollution during normal wearing and storage can be avoided or greatly delayed. And the inner non-woven layer has the characteristics of water absorption and skin friendliness, so that a user feels more comfortable during wearing. The silver-containing nanofiber layer can play an antibacterial role, and the bactericidal effectof the mask is enhanced. And the middle non-woven layer is used for isolating the silver-containing fiber layer from the electrode layer. And the geobacillus fibroin fiber layer can spontaneously generate current under the condition that the flowing airflow contains moisture, so that static electricity in the mask is generated and maintained, and the adsorption capacity of the static electricity to fine particles is maintained and increased.

Description

technical field [0001] The invention relates to the technical field of anti-epidemic protective equipment, in particular to a new type of mask based on protein and moisture to generate static electricity. Background technique [0002] There are a lot of dust, smog, bacteria and viruses in the air that are harmful to the human body. Especially with the rapid spread of the new crown pneumonia virus epidemic around the world, personal protection has become the first pass to prevent the spread of the virus. degree of attention. The demand for masks has shown explosive growth, so that in a short period of time, the world is facing a situation where masks are out of stock and in short supply. [0003] Most of the existing masks are made of one or more layers of fibers through melt-blown, spun-bonded and other production processes, which can to a certain extent play the role of capturing droplets in the airflow, filtering particulate matter, and blocking bacteria and viruses.

Problems solved by technology

However, due to the breath when the human body exhales, the original charge in the mask will be continuously lost, making the existing electrostatic mask a disposable product, which can usually only be used for a few hours.
