Description

Novel mask based on bacillus terreus protein fibers

Technical Field

The invention relates to the technical field of epidemic prevention and protection tools, in particular to a novel mask based on static electricity generated by protein and moisture.

Background

The air contains a lot of dust, haze, bacteria, viruses and other substances harmful to human bodies, and personal protection becomes a first gateway for blocking virus diffusion and is paid more attention. The demand for masks has seen explosive growth, so that the world is faced with a situation of mask dissale and short supply and demand in a short time.

The existing mask is mainly manufactured by compounding one or more layers of fibers through melt-blowing, spun-bonding and other production processes, and can play roles of capturing liquid drops in airflow, filtering particulate matters, blocking bacteria and viruses and the like to a certain extent. However, the mask that is isolated by the aperture is often unable to effectively isolate the nanoparticles such as viruses.

The static electricity can enhance the filtering function of the mask on virus and other fine particulate matters. However, the original charge in the mask is lost continuously due to the breathing of human body, so that the existing electrostatic mask becomes a disposable product and can be used for only a few hours. Therefore, a new technology capable of continuously generating and maintaining static electricity inside the mask is urgently needed to enhance and maintain the adsorption of the mask to fine particulate matters and greatly save resources.

Disclosure of Invention

In order to solve the problems, the invention provides a novel mask based on bacterial protein to generate static electricity, aiming at the defects in the prior art.

In order to achieve the above object, the present invention adopts the following technical means.

A novel mask based on a protein fiber layer of rhizoctonia solani is provided with an inner electrode layer, a hypha protein fiber layer of the rhizoctonia solani, an outer electrode layer, a middle non-woven layer and a silver fiber layer between an inner non-woven layer and an outer non-woven layer.

The protein fiber layer is a multilayer nanofiber membrane prepared by using specific hypha protein produced by using metal reducing bacillus or sulfur reducing geobacillus by adopting a solution electrostatic spinning method. The obtained ground stalk hypha protein is rich in aromatic amino acids, has strong conductivity, and can spontaneously generate current when contacting water

And metal strips are arranged at the outer edges of the outer non-woven layer and the inner non-woven layer and connected with tensioning belts.

The inner non-woven layer and the outer non-woven layer are used for isolating large granular substances. 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. The inner non-woven layer has the characteristics of water absorption and skin friendliness, so that the body feeling is more comfortable when the garment is worn.

The silver-containing nanofiber layer can play an antibacterial role and enhance the bactericidal effect of the mask.

The middle non-woven layer is used for separating the silver-containing fiber layer from the electrode layer.

The hypha protein fiber layer of the ground rod can spontaneously generate current under the condition that moisture is contained in the flowing air flow, so that static electricity in the mask is generated and maintained, and the adsorption force of the static electricity on fine particles is maintained and increased.

The ground stem hypha protein fiber layer is arranged between the outer electrode layer and the inner electrode layer. The area of the inner electrode layer is slightly smaller than that of the protein fiber layer, and the ground rod hypha protein fiber layer can absorb moisture from human breath or air. The conductivity of the protein nanowires, coupled with the chemical nature of the protein surface, combined with the pores between the nanowires inside the film, generates a current between the two electrodes. The best current generation is achieved when the relative humidity of the air stream is 45%. When the ground rod hypha protein fiber layer is in an environment with low humidity, the generated current is obviously reduced, but the power can be generated even in a dry environment of a desert. The relative humidity of the exhaled air of normal human is generally more than 60%, and the requirements of the working conditions of the geobacillus silk protein can be well met.

The voltage generated in the ground rod hyphal protein fibrous layer can be explained by the moisture gradient on both sides of the fibrous layer, and functional groups (such as carboxyl groups) on the surface of the protein provide freely movable protons, so that the moisture gradient can cause an ionization gradient on the carboxyl groups or a concentration gradient on the movable protons. The hole state on the protein fibers and the proton gradient result in the diffusion of protons, which can cause the action of an electric field or similar to the static membrane potential in biological systems. Studies have shown that a sustained voltage of about 0.5 volts can be generated across a 7 micron thick film with a current density of about 17 microamps per square centimeter.

The current can provide static charges for the mask, so that the electrostatic adsorption effect is generated, and the adsorption effect of the mask on viruses, bacteria and other fine particles in the airflow is further improved. The disadvantage of the moisture exhaled by the human body, which often leads to static electricity loss from the mask, is precisely the advantage of generating electricity.

The electrostatic effect can enhance the adsorption of the mask to the particles. When the tiny particle is close to electrified object, because electrostatic induction, the opposite electric charge of electrified object electrical property can be responded to the particulate matter that is close to electrified object one end, because the effect is inhaled mutually to electric charge opposite sex, the tiny particle can be attracted on the gauze mask, and required voltage is not high and energy-conserving relatively more. The voltage or the current can be increased by arranging a plurality of thin films in series or in parallel so as to achieve better adsorption efficiency on the fine particles.

Compared with the prior art, the invention has the beneficial effects that:

the main working part of the invention comprises an inner non-woven layer, an inner electrode layer, a ground rod hypha protein fiber layer, an outer electrode layer, a middle non-woven layer, a silver fiber layer and an outer non-woven layer.

The double electrode layers and the ground rod hypha protein fiber layer can utilize the ground rod hypha protein to combine with water vapor in the air and exhaled by human bodies, so that the characteristic of micro current is generated, a certain amount of static charge is generated and maintained in the fiber, and the adsorption capacity of the novel mask on fine particles is enhanced and maintained.

The outer edges of the outer non-woven layer and the inner non-woven layer are connected with tensioning belts, so that the garment is convenient to wear. The silver-containing nanofiber layer can play an antibacterial role and enhance the bactericidal effect of the mask.
