Generally speaking, the mask consists of at least three layers, including the inner layer, the middle layer as the filter layer, and the outer layer. The mask of the present invention includes a base material for making an outer layer using the following process to make it have luminous protection.

A roll-to-roll type device 106 is configured. The roll-to-roll type device 106 includes at least three rotary shafts 102, at least one of which is placed in a dip tank 104, and the dip tank 104 is used to carry dye. The rotating shaft 102 can be driven by a driving device, such as a motor, to rotate according to a rotating shaft, which causes the soft substrate to move, as illustrated in the direction of the rotating 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 is driven to move through the dip tank 104, where the outside dye is prevented from attaching to the substrate 110. The rotation speed of the rotating shaft 102 can be controlled, which is advantageous for controlling the moving speed and thus the material thickness. The heating device 108 is correspondingly disposed under the horizontally moving substrate 110, and can selectively turn on the heating device to provide a heat source for drying. The heating device 108 may be a light bulb, hot air, electromagnetic radiation, or an infrared heater.

As the process progresses, the substrate is transferred from one end to the other end without being dyed. At this time, the substrate that has been finished with dyeing will be rolled to the other end and collected. Because the base material is flexible, it can be curled at the other end. If necessary, the heating device can be turned on to provide the heat energy required for drying. Afterwards, the rolled substrate can be processed into masks or other articles. If necessary, a buffer layer or a protective layer can be coated on the soft substrate.

In the present invention, non-metallic or non-metallic oxide materials can be used as ultraviolet protection materials to avoid environmental pollution. The use of a flexible substrate allows the material to pass through the rotating shaft to rotating shaft device of the present invention, and a large number of thin films can be manufactured without the process polluting the environment. And the speed of the driving shaft is used to control the film growth thickness, 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 preparing the solution, start the inkjet, spraying, printing or coating process 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 remaining steps are similar. Examples, including selective heating.

Anti-ultraviolet masks can be screen printed, sprayed, dipped or coated with luminous dyes on their surface cloth to achieve the luminous function. If the spraying has anti-ultraviolet rays, the changes can be observed, and the protection function is known. Traditionally, masks have no ultraviolet protection function, let alone observing its protection effect. In fact, traditional masks do not have any luminous protection function, and traditional masks cannot achieve this effect at all. .

In the present invention, the luminous dye is doped into the resin, for example, water-based or natural resin, and can be used in the form of micropowder, capsule, or liquid, and the luminous dye is mixed with the resin. The mixing ratio of luminous dye and resin can be 1:3-1:20, which can be diluted with thinner to adjust the viscosity.

In another embodiment, the luminous dye and polymer fusion procedure can be fused using the following method. For example, the luminous dye and the polymer base material are carried out in a non-woven fabric process, and the luminous dye is dispersed in a carrier and mixed into polyester, nylon, polypropylene, etc.

The above-mentioned luminous dyes contain fluorescent powders, which are generally divided into two types: photo-energy storage luminous powders and radioactive luminous powders. Photoluminescent powder is a fluorescent powder that stores light energy after being irradiated with natural light, daylight light, ultraviolet light, etc. After stopping the light, it slowly releases light in a fluorescent manner. So at night or in the dark, you can still see the glow, which lasts for a few hours to a dozen hours. The luminous powder with radioactivity is mixed with radioactive material in the fluorescent powder, and the radioactive material is continuously used to emit rays to excite the fluorescent powder to emit light. Such luminous powder emits light for a long time but there are doubts about pollution. Luminous materials are mainly ZnS, SrS and CaS, which emit green or yellow light.

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, for example, the middle layer may include a filter layer, an antibacterial layer, or one or two layers.
