Generally speaking, a mask contains at least three layers, including an inner layer, a middle layer as a filter layer, and an outer layer. The mask of the present invention includes a base material with an outer layer made by the following process to make it have ultraviolet protection or anti-virus effects.

A roll to roll device 106 is configured. The roll to roll device 106 includes at least three rotating shafts 102, of which at least one of the rotating shafts is placed in a dip tank 104, which is used for carrying dye. The rotating shaft 102 must be driven by a driving device, such as a motor, so that it rotates according to a rotating shaft and moves the soft substrate. For example, it rotates in the direction of the rotation arrow in the first figure, so that the substrate 110 can be rolled from one end to the other. . During this process, the substrate 110 will be driven to move and pass through the dip tank 104, where the external dye or antiviral component will be prevented from adhering to the substrate 110. The rotation speed of the rotating shaft 102 can be controlled, which is beneficial to control the moving speed and thus the material thickness. The heating device 108 is correspondingly configured on the lower side of the horizontally moving substrate 110, and the heating device can be selectively turned on to provide a heat source required for drying. The heating device 108 can be a light bulb, hot air, electromagnetic radiation or an infrared heater.

As the process progresses, the substrate is transferred from one end of the unimpregnated end to the other end. At this time, the impregnated substrate will be rolled to the other end and collected. Since the substrate has flexibility, it can be crimped on the other end. If necessary, the heating device can be turned on to provide heat energy for drying. The rolled substrate can then be processed into masks or other products, such as anti-viral headgear, bed sheets, duvet covers, pillow cases, blinds, wipes, etc.

The present invention can use non-metal or non-metal oxide materials as the anti-ultraviolet material to avoid environmental pollution. Using a flexible substrate, the material can pass through the shaft of the present invention to the shaft type The film can be produced in large quantities, and the process does not pollute the environment. And the speed of the drive shaft is used to control the thickness of the film, and it can be attached to irregular or uneven surfaces.

Embodiment Referring to the second figure, the device of this embodiment is similar to the first figure. The difference is that this embodiment uses printing, coating, spraying or inkjet printing to coat the solution on the desired flexible substrate. After preparing the solution, start the inkjet, spray, printing or coating process to distribute the material on the soft substrate. If the inkjet printing method is used, the dye pattern can be directly sprayed on the soft substrate. The other steps are similar. Examples include selective heating.

Anti-ultraviolet masks can be sprayed, impregnated or coated with anti-ultraviolet absorbing materials or photochromic dyes on their surface cloth to achieve the anti-ultraviolet function. If the spray has anti-ultraviolet rays, the changes can be observed, and the protection function is known. Traditionally, masks have no UV protection function, let alone observe its protection effect. In fact, traditional masks have no protection function, so it is not conducive to facial cosmetic surgery. maintenance. The most important aspect of post-cosmetic maintenance is to prevent ultraviolet radiation. Therefore, the present invention is very important for post-cosmetic maintenance, and traditional masks cannot achieve this effect at all.

In the present invention, a photo-chromic dye is doped into a resin, such as an aqueous resin, which can be in a micropowder, capsule state, or liquid state, and the photo-chromic dye is mixed with the resin. For example, a water-based resin is mixed with a hydrophilic photochromic dye to prepare the above-mentioned impregnation solution. The mixing ratio of photochromic dye and resin can be 1:5-1:20, which can be diluted with water to adjust the viscosity. Photovariable dyes can absorb sunlight or ultraviolet rays to change the structure, and photovariable dyes undergo reversible chemical changes after being irradiated by sunlight or ultraviolet rays to cause color changes. When not exposed to the above sunlight or ultraviolet rays, the original color can be restored. Photovariable dyes can be selectively doped together with light stabilizers and UV absorbers to help absorb ultraviolet rays. Adding antioxidants or/and UV absorbers can improve anti-light fatigue.

Therefore, please refer to the third figure, which shows a schematic cross-sectional view of the mask of the present invention, which may include three or more layers. This embodiment takes three layers as an example. The outer layer 200 is an anti-ultraviolet layer, and its implementation can refer to the above implementation methods. The middle layer is a filter layer 220 for filtering dust, bacteria, etc. The inner layer 240 can be made of cotton cloth, or can be made of skin-friendly materials, such as ice silk cotton or TPE. Using the above method, the fragrance base material can be made in the inner layer. The principle is to use fragrance, fragrance Essences, essential oils, perfume materials, etc. are added to the production of the inner base material, so that the inner layer of fragrance can be obtained and the effect can be improved. The outer layer or the middle layer can be added with bacteriolytic or antibacterial enzymes to eliminate bacteria. The method can be spraying, dip dyeing, coating or printing. Traditionally, it can only filter but cannot kill viruses. Therefore, in addition to filtering, the present invention can also decompose bacteria and inhibit viruses. In addition, the outer layer 200 or the middle layer 220 can also be added with influenza virus components or sterilizing enzymes to eliminate bacteria and inhibit viruses. The method can be spraying, dip-dyeing, coating or printing. Traditionally, bacteria can only be filtered, but bacteria cannot be killed. Therefore, in addition to filtering, the present invention can also decompose bacteria and inhibit viruses. In addition, the above-mentioned spraying, dipping, coating can also be used to attach antiviral agents to the outer layer 200 or the middle layer 220 to inhibit influenza virus or enterovirus, and so on. The above-mentioned influenza virus components can use cationic organic compounds, cationic metal organic metal compounds (such as organic copper compounds, organic zinc compounds, organic tin compounds, and some other organic metal compounds). In order to avoid washing off, you can add the molten base material in the non-woven process, and then use the non-woven process to make the non-woven fabric, so that it is not easy to lose. Based on the fact that masks are disposable products, they can be made by spraying, dipping, coating or printing as described above. If copper (or silver) ions are used for single storage, neutrality is formed based on the trapped electrons, which tends to lose the antibacterial activity, and nanosilver metal is biologically toxic. The cationic organometallic compound of the present invention can be an organic-inorganic compound using an antiviral organic ligand and an antiviral inorganic cation to form a compound salt.

It must be noted that bacteria are completely different from viruses. Viruses are non-cellular forms composed of a nucleic acid molecule (DNA or RNA) and protein. They are organisms and cannot exhibit life phenomena on their own. An organic species between living organisms. It is neither living nor non-living. It consists of a piece of DNA or RNA in a protective shell. Through the mechanism of infection, these simple organisms can use the host cell system to replicate themselves. . Bacteria are generally single cells with simple cell structure, lacking nuclei and membranous organelles, such as mitochondria and chloroplasts. Based on these characteristics, bacteria belong to prokaryotes. The shape of bacteria is quite diverse, mainly spherical, rod-shaped, and spiral.

The filter layer 220 can use an ultra-microporous filter membrane (PTFE biotechnology membrane) that can filter particles below 0.1-2.5 microns to inhibit PM 2.5 hazards, and can prevent haze, air permeability, and good breathing characteristics. Nanoporous polytetrafluoroethylene (PTFE) membrane, the pore diameter of the nanoporous membrane is smaller than that of the general microporous membrane, and it has a high degree of hydrophobic and oleophobicity, so it has very good moisture permeability, air permeability, water and oil resistance. Resistant to ultra-high water pressure and ultra-high water vapor The vapor transmission rate of PTFE nanoporous film is made of ultra-high crystalline polytetrafluoroethylene material, which is extruded under ultra-high pressure to form a film with extremely fast stretching speed, so that the film has ultra-high strength of nanoporous Three-dimensional structural features. The pore size can be controlled between 0.03 microns (μm) (30 nanometers (nm)) and 15 microns (μm), the thickness is 8-50 microns (μm), and the porosity is as high as 80-97%. The ultra-microporous biotechnology filter membrane replaces the traditional non-woven filter layer with a polymer membrane filter material, with a filtration rate of over 99.9%, which can eliminate viruses, allergens, and fine suspended particles in the air, with high air permeability and no stuffiness. Ultraviolet rays with a wavelength of 100~280 nanometers (nm) have shorter wavelengths, and the stronger the energy contained, the most harmful to the skin is ultraviolet C, but most of it is isolated by the ozone layer in the atmosphere and hardly reaches the ground. The wavelength is 280~320nm, and the energy is the second, causing immediate sunburn on the skin, thickening, dullness, reddening, eye inflammation, pain and drying of the skin, mainly caused by UVB.

In the production method of the present invention, a virus-reducing solution is first prepared, such as (1) preparing an organic compound that inhibits virus surface proteins, and changing the surface protein of the virus by chemisorption to inhibit virus replication; or (2) preparing a metal compound and using Free radical reaction generates hydroxyl free radicals, extracts hydrogen atoms in virus proteins, destroys virus form, and inhibits virus replication; or (3) Use organometallic compounds, which contain metal (including metalloid) and organometal bonded with carbon atoms Compounds, in addition to traditional metal elements, lanthanides, actinides, semi-metals, metalloids (such as boron, silicon, arsenic, selenium) can also bond with carbon to form organometallic compounds. The use of the above substances can destroy the virus surface protein, or destroy the nucleic acid, or destroy the mantle, and reduce the virus activity. For example, the formamide and isonitrile compounds of influenza A virus inhibitors contain R group selected from the group consisting of alkyl, cycloalkyl, aryl, heteroaryl, amino acid and substitutions of the above groups derivative. Formamide and isonitrile compounds are prepared using amines as raw materials through acylation, dehydration, etc., and these formamide and isonitrile compounds and their salts can be used to prepare virus-inhibiting substances. Another preferred example is a peptide or protein-based compound, including one or more proteins, polypeptides or peptides, nucleic acids, peptide nucleic acids, nucleic acid analogs, nucleosides, nucleoside analogs, small organic molecules, polymers, lipids, Steroids, fatty acids, carbohydrates or any combination of the above. The above-mentioned peptide or protein-based compound mainly has an amino acid framework in which the amino acids are linked by peptide bonds. A peptide or protein-based compound may also have other chemical compounds or groups attached to the amino acid framework or backbone, including moieties that contribute to the anchoring activity of the anchoring domain. An extracellular anchoring domain or anchoring domain refers to any entity that can stably bind to an entity located on or on the outer surface of a target cell or adjacent to the outer surface of a target cell. Secondly, in another embodiment, an influenza endonuclease inhibitor with high affinity and binding ability to inhibit the highly active metal compound group of the endonuclease. Another example is when monovalent copper compounds encounter bacteria and viruses, monovalent copper After the ions react with oxygen, hydroxyl groups are produced. These two substances, copper ions and hydroxyl groups, can reduce the number of viruses and bacteria. The monovalent copper ions are separated from the water, and the monovalent copper ions separated from the monovalent copper compounds are phased with the divalent copper ions. Compared with, has the characteristic of being more susceptible to oxidation, so it can produce hydroxyl. Hydroxyl has the effect of inhibiting the reproduction of microorganisms and can exert an antiviral effect.

The cationic metal organic compound of the present invention is a compound of both metal cations and organic materials, that is, the two are chemically combined or processed to produce cationic metal organic compounds, which belong to organic-inorganic compound antiviral agents (materials). For example, synthetic compounds of acylpyrazolone and Ni ⁺ , Cu ²⁺ , Co ²⁺ or Zn ²⁺ have a certain inhibitory effect on Escherichia coli and Staphylococcus aureus, and their antibacterial activity is higher than that of metal ions. This indicates that after the formation of the compound, the transition metal ions have an enhanced effect on the antibacterial activity of the ligand. Another example is the synthesis of tetrathiosemicarbazone and two thiosemicarbazone stable chelate with Ni ⁺ , Cu ²⁺ or Zn ²⁺ , and its antibacterial ability is far better than that of ligands and metal ions alone. Therefore, the organic-inorganic compound of the present invention has the advantages of individual organic and inorganic virus-inhibiting, and has the high efficiency and sustainability of organic antibacterial agents, and the safety and heat resistance of inorganic antibacterial agents. Interfered by ultraviolet rays. In organometallic compounds, the bonding properties of metal and carbon are generally between ionic bonds and covalent bonds. When the electronegativity of the metal is very low (for example, an alkali metal element) or the carbon-containing ligand is a stable carbanion, the bond will be similar to an ionic bond. Carbanions can be stabilized due to resonance or electron-withdrawing substituents (such as trityl anions). In another embodiment, the outer layer or inner layer of the present invention contains an alkali metal or alkaline earth metal crystalline aluminosilicate, which has a strong cation exchange capacity; metal-silicates such as silver or silver and zinc -Silicates have good affinity with organisms. The advantages also include: high safety, durability, broad-spectrum antibacterial properties (change the type of metal ions, can kill different bacteria), and it is not easy to develop resistance. In the filling form, the above-mentioned components are mixed with synthetic fibers to produce fibers. Because it is mixed into the fiber, it has good washing resistance and long effect time. Post-processing form During the post-processing of the fiber, the above-mentioned components are bonded to the surface of the fiber through chemical bonds or hydrogen bonds, and the contact area with the virus is larger (at the same dose). It can use different processes for different needs.

The fourth and fifth figures show that the mask of the present invention has passed the SGS test and passed the ISO 18184 standard, proving that the present invention has a good anti-virus effect. Please refer to the fourth figure, which states that the standard value of good antiviral activity is 3, and the anti-H ₃ N ₂ virus activity of the present invention is 3.4, which is much higher than the standard value. Please refer to the fifth figure, which states that the standard value of good antiviral activity is 3, and the anti-H ₁ N ₁ virus activity of the present invention is above 3.4, which is much higher than the standard value. The invention not only inhibits germs, but also can destroy viruses, so it produces qualitative changes and has new effects. The fourth and fifth diagrams prove that the present invention has a good antiviral effect (anti-H ₃ N ₂ virus activity is 3.4, anti-H ₁ N ₁ virus activity is above 3.4, which is much higher than the standard value). Therefore, this case has substantial Changes and significant improvements in efficacy have unexpected effects.

The mask manufacturing method of the present invention adopts homogeneous materials of the inner layer and the outer layer, and the unit weight of the outer layer is greater than or equal to the unit weight of the inner layer, so that the pressure difference is lower than 5 mmH ₂ O/cm ² . At least one layer (or two layers) is coated with the above-mentioned virus-inhibiting active substance. In order to achieve this goal, a hydrophilic surface (or modified with a hydrophilic surface) must be used. The hydrophilicity forms a bond through hydrogen bonds and water molecules. Destroy organic compounds by attaching surface proteins, change virus surface proteins, produce hydroxyl metal compounds, or both. In addition, the hydrophilic surface can stick bacteria, viruses or other microorganisms, and increase the chance of inhibiting the contact of virus active substances with viruses and bacteria, thereby inhibiting viruses and bacteria. The traditional surface layer is made of water-repellent materials, so this goal cannot be achieved. Traditional masks All are the opposite teachings of this case. In addition, hydrophilic surface modification can use the chelating effect of phytic acid molecules and ferric ions to produce cross-linked complexes on the surface, which has a large number of hydrophilic phosphonic acid groups, making the surface extremely hydrophilic. Phytic acid is an organic phosphoric acid compound extracted from plant seeds. Its toxicity is lower than that of table salt. Its reaction with iron ions is carried out in water and does not involve any organic solvents. It is completely non-toxic, green and environmentally friendly; no complicated equipment is required. The entire reaction can be completed in just a few minutes. It is simple and rapid. The adjustment of surface hydrophilicity has improved the skin-friendly, bionic, lubricating and other aspects of the material.
