The first figure is the device of the invention.

The second figure is the production of the present invention.

The third figure is a mask of the present invention.

The fourth figure is a spectrum chart of ultraviolet absorption.

Generally speaking, a mask includes 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 making an outer layer substrate by the following process so that it has ultraviolet protection effect.

A roll-to-roll device 106 is configured. The roll-to-roll device 106 includes at least three shafts 102. At least one of the shafts is placed in a dip tank 104, and the dip tank 104 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 to move the soft substrate. For example, the rotation in the direction of the rotation arrow in the first figure allows the substrate 110 to be rolled from one end to the other. . In this process, the substrate 110 is driven to move, and passes through the dip tank 104, where the outside dye is prevented from adhering to the substrate 110. The rotation speed of the rotating shaft 102 can be controlled, which is conducive to controlling the moving speed and thus the material thickness. The heating device 108 is correspondingly disposed below the horizontally moving substrate 110, and can selectively turn on the heating device to provide a heat source required for drying. The heating device 108 may be a light bulb, hot air, electromagnetic radiation or infrared heater.

As the process progresses, the substrate is transferred from one end to the other end without being impregnated. At this time, the substrate that has been impregnated will be rolled to the other end and collected. Because the substrate is flexible, it can be crimped at the other end. If necessary, the heating device can be turned on to provide the required heat energy for drying. The rolled substrate can be subsequently processed into masks or other supplies, such as UV-protective umbrella cloth and UV-proof shade cloth. If necessary, a buffer layer or a protective layer can be coated on the soft substrate.

In the present invention, a non-metal or non-metal oxide material can be used as the UV-proof material to avoid environmental pollution. The flexible substrate is used to make the material pass through the rotating shaft to rotating shaft device of the present invention, and a large number of films can be produced, and the manufacturing process does not pollute the environment. The thickness of the film is controlled by the speed of the driving shaft, and it can be attached to irregular or uneven surfaces.

The embodiment refers to the second figure. The device of this embodiment is similar to the first figure. The difference is that this embodiment uses coating, spraying or inkjet print to apply the solution on the desired soft substrate. After the solution is prepared, the inkjet, spraying, printing or coating process is started to distribute the material on the soft substrate. If the inkjet printing method is used, the dye pattern can be sprayed directly on the soft substrate. The rest of the steps are similar. Examples include selective heating.

Anti-ultraviolet masks can spray, dip or coat anti-ultraviolet absorbing materials or photomutation dyes on their surface cloth to achieve anti-ultraviolet function. If the spray has UV protection, you can observe its change, and know the protective function. Traditionally, masks have no UV protection function, let alone observe its protective effect. In fact, traditional masks do not have any protection function, which is not conducive to facial beauty surgery. maintenance. The most important part of post-cosmetic maintenance is to prevent ultraviolet radiation. Therefore, the present invention is very important for post-cosmetic maintenance. Traditional masks cannot achieve this effect at all.

In the present invention, a photo-chromic dye is doped in a resin, such as an aqueous resin. The photo-chromic dye can be mixed with the resin in a micronized powder, a capsule state, or a liquid state. For example, an aqueous resin is mixed with a hydrophilic photochromic dye to prepare the above-mentioned impregnation solution. The photo-mutation dye can be mixed with the resin at a ratio of 1: 5-1: 20, which can be diluted with water to adjust the viscosity. Phototropic dyes can absorb sunlight or ultraviolet rays to change the structure. Photochemical dyes undergo reversible chemical changes after irradiation with sunlight or ultraviolet rays, resulting in color changes. When not exposed to the above sunlight or ultraviolet rays, the original color can be restored. Photomutable dyes can be doped with light stabilizers and UV absorbers to help absorb ultraviolet light. Adding antioxidants and / or UV absorbers can improve anti-light fatigue. In another embodiment, an oil-based photochromic dye may be used, and the resin may be used for printing or inkjet production. The mixing volume percentage value of the oily photomutagenic dye and the resin is about 0.2-0.55. The above photochromic material may be spiropyran, spiroxazine, capsine anhydride, scapranimine, benzopyran, naphthopyran, spirobenzopyran, spironaphthopyran, and spirobenzo Oxazine, spironaphthoxazine, etc. (spiropyrans, spiroxazines, fulgide, fulgimides, benzopyran, naphthopyran, spirobenzopyran, spironaphthopyran, spirobenzoxazine or spironaphthoxazine), but not limited to the above examples.

Synthetic fiber (Synthetic Fiber) is formed by polymer spinning from monomer molecular raw materials obtained in nature. Such as condensation polymers (Condensation Polymer): (A) Polyamide Fiber (Polyamide Fiber): nylon 6 (Nylon 6), nylon 6.6 (Nylon 6.6), nylon 11 (Nylon1); (B) polyester fiber (Polyester Fiber ): PET, PBT, PTT; (C) Addition Polymer: (1) Polyacrylonitrile Fiber: PAN (or Acrylic Fiber); (2) Polyethylene Fiber : PE; (3) Polypropylene Fiber: PP; (4) Polyvinylalcohol Fiber: PVA; (5) Polyvinylchloride Fiber: PVC; (6) Polytetrafluoro Polytetrafluoroethylene Fiber: PTFE; (7) Polyurethane Fiber: PU. Carbon fiber and glass fiber are classified as inorganic synthetic fibers. High-performance fibers include Poly lactic acid, PBO fibers (p-phenylene-2,6-benzobisoxazole), high-strength polyesters, polyamides, polyolefins, para and meta aromatic polyamides, and carbon fibers , High coefficient polyethylene (HMPE), polyphenylene sulfide (PPS), phenolic polymer fiber, polyether ketone (PEEK), etc. Based on the selection of the photo-mutable dye and the processing temperature, the drying temperature is lower than 150 degrees.

Therefore, please refer to the third figure, which discloses a schematic cross-sectional view of the mask according to the present invention, which may include three or more layers. One embodiment includes an outer layer 200 as an ultraviolet shielding layer. For implementation, refer to the foregoing implementation methods. The middle layer is a filter layer 220 for filtering dust, bacteria, and the like, and the inner layer 240 may be a heat-generating or thermal-storage layer to provide a warming effect. Using the above method, it is also possible to make a fragrance base material on the inner layer. The principle is to use fragrance, essence, essential oil, perfume raw materials and other materials added to the base material to make the fragrance inner layer and improve the effect. The outer layer or the middle layer can be added with lysozyme or bactericidal enzyme to eliminate bacteria. The method can be sprayed, dip-dipped, coated or printed. Traditionally, only bacteria can be filtered, and bacteria cannot be killed. Therefore, in addition to filtering, the present invention can also break down bacteria by enzymes. In addition, the outer layer 200 or the middle layer 220 can also be added with influenza virus lysozyme or bactericidal enzyme to eliminate bacteria. The method can be sprayed, impregnated, coated or printed. Traditionally, only bacteria can be filtered, and bacteria cannot be killed. Therefore, in addition to filtering, the present invention can also break down bacteria by enzymes. In addition, the above-mentioned spraying, dipping, and coating can also be used to attach the antiviral agent to the outer layer 200 or the middle layer 220 to inhibit influenza virus or enterovirus and the like. The filtering layer 220 can be an ultra-microporous filtering membrane (nano-microporous polytetrafluoroethylene; PTFE membrane), which can filter particles below 0.1-2.5 microns in order to suppress the harm of PM 2.5, and can prevent haze, breathability and good breathing characteristics. Nano-microporous polytetrafluoroethylene (PTFE) film. The nano-microporous membrane has a smaller pore size than ordinary microporous membranes. It has a high degree of hydrophobic and oleophobic properties, so it has excellent moisture permeability, breathability, and water and oil resistance. The ultra-high water pressure and ultra-high water vapor permeability PTFE nano-microporous film is made of ultra-high crystalline polytetrafluoroethylene material, extruded into a film under ultra-high pressure and matched with extremely fast stretching speed, so that The film has three-dimensional structural characteristics of ultra-high strength with nanopores. The pore diameter can be controlled between 0.03 micrometers (30 nanometers (nm)) and 15 micrometers (μm), the thickness is 8-50 micrometers (μm), and the porosity is as high as 80-97%. The ultra-micropore biotechnology filtration membrane replaces the traditional non-woven filter material layer with a polymer film filter material, with a filtration rate of more than 99.9%, which can exclude viruses, allergens and fine suspended particles in the air, is highly breathable and not stuffy.

Wavelengths of 100 to 280 nanometers (nm) have shorter wavelengths and the stronger the stored energy, the most harmful to the skin is ultraviolet C, but most are isolated by the ozone layer in the atmosphere and hardly reach the ground. The wavelength is 280 ~ 320 nanometers, followed by its energy, which causes immediate sunburn of the skin, making the skin's keratin thick, dull, red, keratitis, and painful, which is mainly caused by UVB. The fourth figure is the ultraviolet transmittance chart. It can be seen that most of the ultraviolet band is absorbed. For example, the transmittance of ultraviolet band below 310 nm is less than 10%, which means that more than 90% of strong ultraviolet rays are absorbed. The main reason is that the gas exchange rate of the mask must meet the requirements, so the mask cannot be completely airtight. Therefore, based on the requirements of ultraviolet absorption and gas penetration, it may be necessary to sacrifice the amount of ultraviolet absorption and adopt a compromise solution. Therefore, it can be seen that this solution can filter more ultraviolet rays with a higher energy below 310 nm (the transmission rate is less than 10%).

The inner layer adds components such as zirconia to the fiber, so it can convert visible light into far-infrared rays to release thermal energy. The other kind weaves heat-generating fibers into the fabric, such as Acrylate, which absorbs and releases heat from the fiber itself. The fiber absorbs moisture released from the human body and condenses it into heat emitted by water. You can also add elements that generate infrared rays, such as ceramic materials, which absorb visible light and convert them into infrared rays, and then convert them into heat energy to increase the temperature. Wool can also be used to absorb human moisture and form condensation heat, which is then released. The above-mentioned adding a far-infrared ceramic component to the fiber, such as zirconia, zirconia, etc., reflects the far-infrared emitted by the human body and converts it into thermal energy to achieve a fever effect. Acrylate heating fiber is a material that heats itself by heating itself. The heating fiber can generate heat by absorbing the sweat and moisture emitted by the human body, so that the space in the clothes is kept warm and comfortable. Acrylate can also deodorize acidic and alkaline odors through neutralization. Use the "condensation heat effect" to absorb human moisture. When the gas is liquefied, the temperature is released. This temperature is called the freezing point. Acrylate heating fiber is the principle that the temperature released when the water vapor that cannot be seen by the human body reaches the freezing point becomes water (liquefaction) is absorbed by Acrylate and then exothermic. Another embodiment uses skin-friendly materials and can control thermal convection and resist thermal radiation emission, such as TENCEL acrylic fiber.

Using hollow fiber sections, in addition to relatively reducing the specific gravity of the fiber, the fabric appears lighter; and it effectively retains and isolates air to achieve thermal insulation. The cross section of the fiber is hollow, and the air layer inside the fiber is used to block the loss of body temperature to achieve the effect of keeping warm. Thermal microfiber material used, the diameter of less than 2 μ m microfine fiber, PET fiber nonwoven fabric can be effectively isolated from the air and retain more of the radiation reflected by the body heat.

PCM phase transfer material makes the fabric have the special functions of heat absorption and heat release to obtain excellent thermal insulation effect. For example Outlast® fiber. Phase change material (PCM) is used to continuously adjust and balance with the microclimate area between human clothes and the surrounding environment, so as to adjust the temperature of overheating or cooling to the most suitable level. It can absorb excessive heat from the human body, thereby reducing the humidity of the clothes and maintaining the comfort of the wearer; and when the amount of exercise decreases or the end of the exercise, the stored heat energy is released, so that the wearer will not be cold.

In addition, HEPA (High-Efficiency Particulate Air) can also be used as a filter layer, that is, a HEPA filter layer, that is, a high-efficiency air particulate filter. High-efficiency filter materials are usually made of random chemical fibers, such as polypropylene fibers (polypropylene) or polyester fibers (polyester), non-woven fabrics or glass fibers, and a flocculent structure with a diameter of about 0.5 to 2.0 microns is used to Remove particles. In addition, polymers composed of hydrophilic and water-repellent materials can also be used. The hydrophilic substance has a molecular chain structure inside, and the molecular chain has a positive and negative charge, which can adsorb a single water vapor molecule and accelerate the speed of water vapor passing through the film , Such as the use of polyester ether (TPEE) material, 70% polyester (water repellent) and 30% polyether ester (hydrophilic) composition, the use of polyether esters, so that the product has the concept of recycling. Its hydrophilic molecules absorb moisture and use physical and chemical processes to quickly remove moisture from the fabric layer. With a thickness of only 5 μm , the film is one of the lightest products on the market. In addition, a thin and durable film made of polyester fiber can be used, which has high waterproof and breathable functions, such as the film with the trade name ECO STORM. In addition, the membrane material is TEEE (a copolymer of phenyl ester and polyether glycol), which releases water vapor by absorbing and diffusing, has non-porosity and does not cause blockage, and the moisture permeability after bonding is still as high as 8000 ~ 10000g / m2 / Day is a high-permeability film: waterproof, breathable, flexible, environmentally friendly, and reusable. In another embodiment, a film with a trade name of DINTEX® can be used. The main material is polymer elastomer polyurethane (TPU;), which has good elasticity and high strength, and has a thickness of only 0.012 to 0.025 mm in water resistance. The introduction of hydrophilic groups in the material makes the film have excellent water permeability in addition to TPU, which has high water resistance. Cooperate with the processing technology of the textile industry, greatly increase the added value, good weather resistance, environmental protection and non-toxic, recyclable and decomposable. In the embodiment, the solvent can be used to generate a hole path in the PU resin by a water bath exchange method or a hot air method to achieve a moisture permeability effect. Polyurethane (TPU) has a simple molecular main structure, containing nitrogen N, hydrogen H, carbon C, and oxygen O. There is no air pollution problem when the incinerator is burned. In addition, polypropylene PP and polyethylene PE porous membranes can be used to mix calcium carbonate powder with PE and PP resins, and then through a two-way extension method, due to the incompatible interface characteristics of calcium carbonate powder and resin. Among them, the above-mentioned filter film is supported on both sides through a polymer layer.
