The third figure shows the mask of the present invention.

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 manufacturing process to make it have ultraviolet protection effect and inhibit virus.

A roll to roll device 106 is configured. The roll to roll device 106 includes at least three rotating shafts 102. At least one of the rotating shafts is provided in a dip tank 104, which is used to carry dyes. . 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 the soft substrate is moved. For example, the rotating arrow in the first figure rotates, so that the substrate 110 can 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 dye is attached 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, and the substrate that has been impregnated 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 present invention can use non-metal or non-metal oxide materials as the anti-ultraviolet material to avoid environmental pollution. The use of a flexible substrate allows the material to pass through the rotating shaft to the rotating shaft device of the present invention, so that a large number of films can be produced, and the manufacturing 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.

The embodiment refers to the second figure. The device of this embodiment is similar to the first figure, except that this embodiment uses 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. Using the inkjet printing method, the dye pattern can be sprayed directly on the soft substrate, and the remaining steps are similar to the above embodiment, including 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 functions. 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 their protection effects. In fact, traditional masks do not have any protection function, so it is not conducive to facial cosmetic surgery. maintenance. One of the most important aspects of post-cosmetic maintenance is to prevent ultraviolet rays. Therefore, the present invention is very important for post-cosmetic maintenance. Traditional masks cannot achieve this effect at all.

In the present invention, photochromic dyes are doped into resins, such as water-based resins, and the photochromic dyes can be mixed with resins in micropowder, capsule state, 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 their structure, and photovariable dyes undergo reversible chemical changes after exposure to 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. The photochromic material can be spiropyran, spirooxazine, fulgide, fulgide imine, benzopyran, naphthopyran, spirobenzopyran, spironaphthopyran, spirobenzopyran Oxazines, spiroxazines, etc. (spiropyrans, spiroxazines, fulgide, fulgimides, benzopyran, naphthopyran, spirobenzopyran, spironaphthopyran, spirobenzoxazine, or spironaphthoxazine), but not limited to the above examples.

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 mask, pain and drying, mainly caused by UVB. Because the gas exchange rate of the mask must meet the regulations, 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.
