The third picture shows a new type of mask.

The fourth figure is the spectrum of ultraviolet absorption.

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 new type of mask includes the following manufacturing process to make an outer base material, so that it has the effect of ultraviolet protection and the function of keeping the face warm.

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, in which the external dye 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. Subsequently, the rolled substrate can be processed into masks or other products, such as anti-ultraviolet umbrella cloth and anti-ultraviolet sun-shading cloth. If necessary, a buffer layer or a protective layer can be coated on the soft substrate.

The new model can use non-metal or non-metal oxide materials as the anti-ultraviolet material to avoid environmental pollution. Utilizing a flexible base material, the material has to pass through the rotating shaft of the present invention to rotate Shaft type device, can produce a large number of films, 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, except that this embodiment adopts 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 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 part of post-cosmetic maintenance is to prevent ultraviolet rays. Therefore, the new model is very important for post-cosmetic maintenance, and traditional masks cannot achieve this effect at all.

In the new type, photo-chromic dyes are doped into resins, such as water-based resins, and the photo-chromic dyes can be mixed with resins in micropowder, capsule or liquid state. 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-mentioned 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. In another embodiment, oil-based photochromic dyes can be used in combination with resins, and printed or inkjet can be used. The mixing volume percentage of oily photochromic dye and resin is about 0.2-0.55.

Synthetic fiber is formed into fiber by polymerization spinning method from monomer molecular raw materials obtained from nature. Such as condensation polymer (Condensation Polymer): (A) Polyamide Fiber (Polyamide Fiber): Nylon 6 (Nylon 6), Nylon 6.6 (Nylon 6.6), Nylon 11 (Nylonl); (B) 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) Polyvinyl Chloride Fiber (Polyvinylchloride Fiber): PVC; (6) Polytetrafluoroethylene Fiber: PTFE; (7) Polyurethane Fiber: PU. Carbon fiber, glass fiber, etc. are classified as inorganic synthetic fiber. High-performance fibers include polylactic acid (Poly lactic acid), PBO fiber (p-phenylene-2,6-benzobisoxazole), high-strength polyester, polyamide, polyolefin, para and meta aromatic polyamide, carbon fiber , High modulus polyethylene (HMPE), polyphenylene sulfide (PPS), phenolic polymer fiber, polyether-based ketone (PEEK), etc. Based on the above-mentioned selection of photochromic dyes and processing temperature, the drying temperature is lower than 150 degrees.

Therefore, please refer to the third figure, which shows a schematic cross-sectional view of the new type of mask. It can include three or more layers. An embodiment includes the outer layer 200 as an anti-ultraviolet layer. For implementation, refer to the above implementation methods. The middle layer is a filter layer 220 to filter dust, bacteria, etc., and the inner layer 240 can be a heat or heat storage layer to provide warmth retention. Using the above method, the fragrance base material can also be made in the inner layer. The principle is to use fragrance, essence, essential oil, perfume raw materials, etc. to be added to the inner base material, so that the inner layer of the 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 bacteria, but cannot kill bacteria, so in addition to filtering, the new type can also decompose bacteria by enzymes. In addition, the outer layer 200 or the middle layer 220 can also be added with influenza virus bacteriolytic or sterilization enzymes to eliminate bacteria. The method can be spraying, dipping, coating or printing. Traditionally, it can only filter bacteria, but cannot kill bacteria, so in addition to filtering, the new type can also decompose bacteria by enzymes. 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 filter layer 220 can adopt an ultra-microporous filter membrane (nano-microporous polytetrafluoroethylene; PTFE 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. The ultra-high water pressure and ultra-high water vapor transmission rate 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. The film has the characteristics of ultra-high strength three-dimensional nanoporous structure. 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. The fourth figure is the ultraviolet transmittance graph. It can be seen that most of the ultraviolet band is absorbed. For example, the transmittance of the ultraviolet band below 310 nm is less than 10%, which means that more than 90% of the strong ultraviolet rays are absorbed. The main reason is that the gas exchange rate of the mask must meet the regulations, so the mask cannot be completely airtight. Therefore, based on the requirements for UV absorption and gas penetration, it may be necessary to sacrifice UV absorption and adopt a compromise solution. Therefore, it can be seen that this solution can filter the higher-energy ultraviolet rays below 310 nm (the penetration rate is less than 10%).

The inner layer adds zirconia and other ingredients to the fiber, so it can convert visible light into far infrared to release heat. The other is woven into fabrics with heating fibers, such as Acrylate, which uses the fiber itself to absorb moisture and release heat. The fiber absorbs moisture released by the human body and condenses it into the heat released by water. It is also possible to add infrared-generating elements, such as ceramic materials, which can be converted into infrared by absorbing visible light and then converted into heat to increase the temperature. Wool can also be used to absorb human body moisture to form condensation heat and then release. The above-mentioned adding far-infrared ceramic components, such as zirconia, zirconium carbide, etc. to the fiber, reflects the far-infrared rays emitted by the human body and converts it into heat energy to achieve the heating effect. Acrylate heating fiber is a material that heats itself and warms the body. The heating fiber can absorb the sweat and moisture released by the human body to generate heat, keeping the space in the clothes warm and comfortable. Acrylate can also deodorize acid and alkaline odors through neutralization. Use "condensation heat effect" to absorb body moisture. When the gas is liquefied, it will release temperature, which is called the condensation point. Acrylate heating fiber uses the principle that the temperature released when the water vapor invisible to the human body reaches the condensation point and becomes water (liquefied) is absorbed by Acrylate and then released. Another embodiment uses skin-friendly materials that can control heat convection and resist heat radiation, such as TENCEL acrylic fiber.

Using the hollow fiber section, in addition to reducing the relative weight of the fiber, the fabric is lighter; it also effectively retains and isolates the air to achieve the heat preservation effect. The fiber section is hollow, and the air layer inside the fiber prevents the loss of body temperature and achieves the effect of keeping warm. The ultra-fine fibers used in thermal insulation materials, the ultra-fine fibers with a diameter of less than 2μm, and PET fiber non-woven fabric can effectively retain more air insulation and reflect the heat radiated by the human body.

The PCM phase transfer material makes the fabric have special functions of absorbing and releasing heat to obtain an excellent thermal insulation effect. For example Outlast® fiber. Phase Change Material (PCM) is used to continuously adjust and balance the microclimate area between human clothes and the surrounding environment, and then adjust the overheated or overcooled temperature to the most suitable level. It can absorb too much 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 drops or the exercise ends, the stored heat energy is released to prevent the wearer from catching cold.

In addition, HEPA (High-Efficiency Particulate Air) can also be used as the filter layer, that is, the HEPA filter layer, that is, the high-efficiency air particulate filter. The filter material of the high efficiency filter is usually made of random chemical fibers, such as polypropylene fiber (polypropylene) or polyester fiber (polyester) non-woven fabric or glass fiber, and a flocculent structure with a diameter of about 0.5 to 2.0 microns is used to remove particles . In addition, a polymer composed of hydrophilic and water-repellent substances can also be used. The hydrophilic substance has a molecular chain structure with positive and negative charges on the molecular chain, which can adsorb individual water vapor molecules and accelerate the speed of water vapor passing through the film. , Such as the use of polyester ether (TPEE) material, 70% polyester (water repellency) and 30% polyether ester (hydrophilic) composition, the use of polyether ester, the product has the concept of recyclability. Its hydrophilic molecules absorb water vapor and use physical and chemical processes to quickly discharge water vapor out of the fabric layer. The thickness of the film is only 5μm, which is one of the lightest products on the market. In addition, thin and durable films made of polyester fibers can be used, which are highly waterproof and breathable, such as the film under the trade name ECO STORM. In addition, the membrane material can be TEEE (copolymer of phenyl ester and polyether glycol), which releases water vapor through absorption and diffusion, which is non-porous and does not cause blockage. After bonding, the moisture permeability is still as high as 8000~10000g/m2/ day, a high moisture permeability film: waterproof, breathable, flexible, environmentally friendly, and reusable. In another embodiment, a film with the trade name DINTEX® can be used, with polymer elastomer polyurethane (TPU;) as the main material, which has good elasticity and high strength, and has a thickness of only 0.012~0.025mm in terms of waterproof properties. The introduction of hydrophilic groups in the material makes the film TPU has high water resistance and excellent moisture permeability. Cooperate with the textile industry's laminating processing technology to greatly increase the added value, good weather resistance, environmental protection, non-toxic, recyclable and decomposable. The embodiment may adopt a water bath exchange method or a hot air method to cause the solvent to create a hole path in the PU resin 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 burns. 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, through the incompatible interface characteristics of calcium carbonate powder and resin. Among them, the above-mentioned filter membrane is supported by high molecular polymer layers on both sides.

The advantage of the new model is that the mask with far infrared material can keep the face warm.
