The above aspects and advantages of the present invention will be more readily understood from the following detailed description of the invention. Wherein: the first figure is a schematic diagram of an embodiment of the invention.

The second figure is a schematic view of an embodiment of the invention.

The third figure is a schematic view of an embodiment of the invention.

The fourth figure shows the ultraviolet transmittance of the invention by SGS.

In the following description, various specific details are set forth to provide a comprehensive understanding of the embodiments of the invention. The present invention will be described in detail with reference to the preferred embodiments and the accompanying drawings. It will be understood by those skilled in the art that the practice of the invention does not require one or more specific details or other specific methods. The present invention can be applied to various fibers, and the following description will be made.

The UV-resistant mask can be sprayed or coated (for example, printed as an example of coating) with an ultraviolet-resistant material or a photo-induced dye to achieve an ultraviolet-resistant function. If sprayed with anti-UV can change the liver tea, and learn about the protective function, the traditional mask does not have the function of protecting ultraviolet rays, let alone observe the protective effect. In fact, the traditional mask does not have any protective function, so it is not conducive to facial cosmetic surgery. After maintenance. The most important part of cosmetic postoperative maintenance is to prevent ultraviolet radiation. Therefore, the present invention is very important for cosmetic postoperative maintenance, and conventional masks are completely incapable of achieving this effect.

In the present invention, a photochromic (Photo-Chromic) dye is doped into a high molecular polymer, and the photochromic dye can be mixed with a high molecular polymer in a fine powder or capsule state. The method of production can also be applied to the surface of the cloth. Since the present invention is doped and fused in the fiber before spinning, it is not easily damaged by scratching, tearing, or impact, but if it is not convenient for production and cost considerations, spraying can be employed. Photochromic dyes can absorb sunlight or ultraviolet light to change the structure, and produce color changes mixed in the medium, such as high molecular polymers. The above fusion means comprises dissolving the molten polymer in a warmed polymer or dissolving the photo-induced dye in a polymer solution to be substantially uniformly distributed therein. In addition, in this stage, it is conceivable to add a dye or a color master to facilitate the adjustment of the color after spinning. The addition of this stage allows the dye to be evenly distributed in the overall spun fiber, rather than being colored on the fiber surface during spinning, resulting in improved color stability.

A photochromic dye fused within a fiber produces a reversible chemical change upon exposure to sunlight or ultraviolet light resulting in a color change. When not exposed to the above sunlight or ultraviolet light, the original color can be restored. The photochromic dye can be doped with a polymer and a UV absorber to selectively absorb ultraviolet rays. The addition of antioxidants or/and UV absorbers to high molecular weight polymers can improve light fatigue. The above photochromic material may be spiropyrans, spiroxazines, fulgide, fulgimides, benzopyran, naphthopyran, spirobenzopyran, spironaphthopyran, spirobenzoxazine or spironaphthoxazine, but is not limited to the above examples.

Synthetic Fiber, which is formed by polymer spinning by a monomeric molecular material obtained in nature. For example, Condensation Polymer: (A) Polyamide Fiber: Nylon 6 (Nylon 6), Nylon 6.6 (Nylon 6.6), Nylon 1 (Nylon 1); (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) Polytetrafluoroethylene Polytetrafluoroethylene Fiber: PTFE; (7) Polyurethane Fiber: PU. Carbon fiber, glass fiber, etc. are classified as inorganic synthetic fibers. High functional fibers include poly lactic acid, PBO fiber (p-phenylene-2, 6-benzobisoxazole), high strength polyester, polyamide, polyolefin, para- and meta-aromatic polyamine, carbon fiber , high coefficient polyethylene (HMPE), poly Phenyl sulfide (PPS), phenolic polymer fibers, polyether ketone (PEEK), P84, and the like. If polypropylene fibers are to be used, it is preferred to use grafted polypropylene fibers to be dyed after blending with other materials. In addition, conventional non-chromic dyes and color-changing dyes are added to the plastics in the preparation of the base masterbatch, such as polypropylene, at a temperature of 140 to 180 degrees Celsius.

In the case of a synthetic fiber, first, a base material of a polymer or a polymer and a photo-induced dye (if a thermotropic dye is used, in which case energy absorbed by ultraviolet rays is absorbed to cause color change), step 100, if To adjust the color, you need to prepare a traditional dye (non-photoinduced) dye or color masterbatch. The photochromic dye or the thermotropic dye may be used or the discoloration molecule may be added to the polymer or the resin material. The base material and the photochromic dye before the fiber spinning may be powder, capsule, liquid, solution. Or plastic masterbatch. The mixing ratio of the photochromic dye to the polymer is about 0.01% to 0.5% by weight (w/w); or 0.5% to 0.1% or 0.1% to 1.5%. Then, the two materials are stirred and uniformly heated to melt the base material of the polymer or polymer to be fused, and the heating fusion temperature is lower than the dissociation temperature of the photo-induced dye, step 110. For example, the photo-induced material of the above ratio and the high-molecular polymer may be mixed, and the mixing concentration thereof is related to the color-changing effect. The selection of the powder and the processing temperature based on the above photochromic dye does not require the use of a dispersing agent. For example, the temperature is 150-180 or 180-220 degrees. In the embodiment, powder, capsule, liquid, and solution can be used, and it is not necessary to prepare a masterbatch when the wire is drawn in situ. However, the masterbatch facilitates the convenience of processing in a different place. Therefore, the mixed pre-spinning material can be first made into a polymer masterbatch.

The invention discloses a photochromic composition which is prepared by using a fiber-forming polymer as a base material, wherein a photochromic dye is doped therein, and the photochromic dye is heated or solution-fused, wherein the processing temperature is low during mixing. The dissociation temperature of the photochromic dye. Before the above production process, the plastic may be dried, and the polymer and the photo-induced dye may be mixed and processed according to the amount and the material, and then processed. The mixing ratio of the two can be tens of thousands to one ten thousand according to different purposes; one ten thousandth to five ten thousandth; one ten thousandth to one thousandth; one thousandth To one-tenth or one-tenth of a tenth. In summary, the plastic and the mixed photo-induced material are dried, stirred to make it uniform, and then fed in a spinning device. Different temperatures and concentrations affect the depth of the basic color, so it can be used to control the desired color with non-chromic dyes. In addition, the processing temperature must be heated and mixed at a temperature lower than the photodissociation dye dissociation temperature to facilitate the production of the raw yarn. Therefore, different temperatures must be adjusted to match different photo-induced materials. Photoinduced materials are produced after exposure to sunlight or ultraviolet light Heat changes. When not exposed to the above sunlight or ultraviolet light, the original color can be restored. Photochromic dyes absorb sunlight or ultraviolet light to produce color changes, so they can absorb ultraviolet light, and can cause the color change of the fiber body, increase the fashion effect, and also make the anti-UV look and add antioxidants and / and UV absorbers. Can improve resistance to light fatigue.

The light (or thermal) color-changing dye is uniformly mixed with the base polymer or polymer material to form a master batch. When the spinning is performed, the mixed polymer base material is melted and subjected to spinning, and in step 120, the spinning technique and the process of the natural fiber, the semi-synthetic or the synthetic fiber are known, and the pre- and post-drawing treatment procedures are also known. It is understandable to those of ordinary skill in the art, and therefore will not be described.

After the spinning process is completed, the raw yarn is obtained, and various fabrics 130 can be woven, plain woven or knitted, which is called a woven fabric. Various other procedures, such as dyeing, embossing, or patterning, are well understood by those of ordinary skill in the art, and therefore will not be described.

The above procedure for fusion with a polymer can be fused by the following method. For example, a melt spinning method: melt-spinning a photo-induced material or a color-changing material with a polymer base material, or dispersing a photo-induced material in a resin carrier capable of being mixed with a spinning polymer, and then mixing the polyester Melt spinning is carried out in a polymer such as nylon or polypropylene. In another embodiment, the photo-induced material and the transfer-preventing aid may be directly added to the solution of the polymer material by solution spinning, and then spun to obtain a photo-variable fiber. Compared to melt spinning, this method has a lower spinning temperature and does not cause oxidation or thermal decomposition problems. In another embodiment, the photo-induced material or the color-changing material may be dissolved in a suitable solvent and then mixed with a binder such as a polymer or a resin liquid to prepare a photochromic material slurry in which the fiber or fabric is placed. By performing a coating treatment in the liquid, fibers having discoloration properties can be obtained by first drawing the wire and then dip-coating with the photochromic mud. The composite spinning method is to use a photochromic material as a core, a general fiber as a sheath, and a common melt spinning to obtain a sheath-core composite fiber.

The solution spinning method is exemplified by an example, but the following methods and basic materials are not limited, and only one embodiment is provided, such as preparing a cellulose acetate, an acrylonitrile-based polymer and a solvent to form a spinning raw material solution, and the solvent can dissolve the cellulose acetate. Aromatic, acrylonitrile-based polymers, such as inorganic acids, inorganic salts. Such solvents are within the skill of the art and should be understood by those of ordinary skill. Mixing and stirring while doping the photochromic dye to A spinning raw material solution was produced. The fiber-formed end-stretched yarn was produced by using a known spinning nozzle using a spinning raw material solution as a raw material. The stretched filament is then stretched several times longer. The dry spinning method can also be used, and those skilled in the art should understand it in the art field, and therefore will not be described.

The above method does not change the original process, and does not increase the process. Before the spinning, the light (or heat) dye is added to the plastic to be mixed, and the polymer is fused with the polymer to make it evenly distributed. In polymer materials. Thereafter, the drawn fiber has a photo-induced dye uniformly distributed in the fiber to become a part of the fiber. Or after the spinning, mixing with the mud; another method is to fuse in the spinning process, the composite spinning method is to use the photochromic dye as the core, the general fiber as the sheath, and the common-spinning to obtain the sheath-core composite. fiber. This method preferably incorporates a photochromic dye into a resin carrier as a spinning material. In other embodiments, materials such as polyester, nylon, vinylon, polypropylene, and the like may be blended with natural fibers such as cotton, wool, silk, and hemp.

Another embodiment of the present invention coats an ultraviolet absorbing material or a light or thermochromic dye to cause a chemical change to cause a color change effect, which not only achieves an ultraviolet absorbing effect but also causes ultraviolet protection, which is seen as a result of color change. To enhance consumer trust. In addition, recycled PET bottles can also be used as the above-mentioned polymer materials to achieve environmental protection. In addition, the processing temperature of the present case needs to be lower than the dissociation temperature; and when the polymer and the ultraviolet absorbing dye are doped, a color masterbatch or a conventional plastic dye is added to uniformly distribute it in the polymer base material. The coating process is such that the hydrophilic dye adheres to the outer layer of the water repellent fabric, so the inventors have painstakingly studied to mix the photo or thermochromic dye with the resin, such as light or thermochromic dye and resin at a ratio of 1:1-1. : 9% by weight of the mixture, and adjust its adhesion coefficient below 20, it can effectively adhere without falling off.

Therefore, please refer to the second drawing, which discloses a schematic cross-sectional view of the mask of the present invention, which may include three or more layers. The embodiment uses three layers as an example. The outer layer is an ultraviolet protection layer 200, and the embodiment can be referred to the above embodiments, including using a sprayed fabric or a color-changing fiber fabric. The middle layer is a filter layer 220 for filtering dust, bacteria, etc., and the inner layer 240 can be made of cotton cloth or a skin-friendly material such as ice silk cotton material or TPE.

The above substrate is blended with natural fibers or semi-synthetic fibers or synthetic fibers.

If it is limited by the physical limitation of the spinning process machine, and the process conversion or output is unfavorable, in another embodiment, the outer layer of the above-mentioned mask is made of non-woven fabric, and the spraying process can be omitted, please refer to FIG. In addition to the dye doping and fusion into the cloth, the invention is not subject to the physical limitation of the spinning machine, and thus is not easily damaged by scratching, tearing, impacting. The fusion means comprises heating the molten polymer or dissolving the photo-induced dye in a polymer solution to be substantially uniformly distributed therein. In addition, in this stage, it is conceivable to add a dye or a color master to facilitate color adjustment. Adding at this stage allows the dye to be evenly distributed throughout the fabric, resulting in improved color stability. The present invention uses a photo-induced dye to be fused in a cloth, and the dye undergoes a reversible chemical change after being irradiated with sunlight or ultraviolet rays to cause a color change. When not exposed to the above sunlight or ultraviolet light, the original color can be restored. The photochromic dye can be doped with a polymer and a UV absorber to selectively absorb ultraviolet rays. The addition of antioxidants or/and UV absorbers to high molecular weight polymers can improve light fatigue. The above photochromic material may be spiropyran, spirooxazine, fulgide, cuminimide, benzopyran, naphthopyran, spirobenzopyran, spironaphthylpyran, spirobenzene Oxazine, spironaphthoxazine, etc. (spiropyrans, spiroxazines, fulgide, fulgimides, benzopyran, naphthopyran, spirobenzopyran, spironaphthopyran, spirobenzoxazine or spironaphthoxazine), but not limited to the above examples.

In an example, a base material of a polymer or a polymer and a photo-induced dye are first prepared (if a thermotropic dye is used, the energy of the ultraviolet light is absorbed to cause color change), and in step 300, the color is adjusted. , you need to prepare a traditional dye (non-photoinduced) dye or color masterbatch. A photo-induced dye or a thermotropic dye may be used or a color-changing molecule may be added to the polymer or resin material, and the above-mentioned base material and The photochromic dye can be in the form of a powder, a capsule, a liquid, a solution or a plastic masterbatch. Then, the two are stirred and mixed uniformly, and the base material of the polymer or polymer is heated and melted to be fused, and the heating fusion temperature is lower than the dissociation temperature of the photo-induced dye, refer to step 310. For example, the photo-induced material of the above ratio and the high-molecular polymer may be mixed, and the mixing concentration thereof is related to the color-changing effect. If the above photochromic dye is selected from a powder and a processing temperature, it is not necessary to use a dispersing agent. For example, the Celsius temperature is 150-180 or 180-220 degrees. In the examples, powdery, capsular, liquid, solution photophotosensitive dyes can be used.

The present invention is doped with a high molecular polymer doped photochromic dye, either by heating fusion or solution fusion, wherein the temperature at the time of mixing is lower than the dissociation temperature of the photochromic dye. The polymer may be dried before the above production process, depending on the amount and material, and may be mixed for 1 to 5 hours, and then the polymer and the photo-induced dye are mixed and processed. In summary, the plastic and the mixed photo-induced material are dried and stirred to make it uniform. Different temperatures and concentrations affect the depth of the basic color, so it can be used to control the desired color with non-chromic dyes. Photoinduced materials undergo thermal changes after exposure to sunlight or ultraviolet light. When not exposed to the above sunlight or ultraviolet light, the original color can be restored. Photochromic dyes absorb sunlight or ultraviolet light to produce a color change, so they can absorb ultraviolet light, and can cause the color of the fiber body to change, increase the fashion effect, and also make the anti-UV look, and add antioxidant or / and UV absorption. The agent can improve the anti-light fatigue.

The light (or thermal) color-changing dye is uniformly mixed with the base polymer or polymer material, and when it is subsequently carried out, the mixed polymer base material is placed in a solution tank of the non-woven process, see step 320. A non-woven fabric, also called a non-woven fabric, is processed by a needle rolling machine or a carding machine, and a cloth is produced by high pressure forming or bonding. The non-woven fabric may be rayon or synthetic fiber, and the raw material often contains polypropylene (PP). Non-woven fabrics are not woven from warp and weft, and the non-woven fabrics vary with the construction method. For example, the needle rolling method is a continuous upper and lower stab through thousands of needles. Therefore, the present invention can shorten the process, It is not subject to the physical limitation of the drawing machine and the number of drawn yarns.

The process of the invention can adopt Electrospinning (ES), Force spinning (FS), Solution blow spinning (SBS), Electroblowing (EB), and composite spinning process. (Islands in the sea, Segmented Pie, and side by side including SB and MB), Spunbonding (SB), Meltblown non-woven fabric Cheng (Meltblowing; MB). For example, U.S. Patent No. 7,931,456, entitled "Electroblowing web formation", proposes an electrospray spinning process; U.S. Patent No. 6,800,226 discloses a spunbond nonwoven process. In general, the non-woven process consists of several basic components: high-voltage power supply, solution tank, nozzle, and collector. The above polymer and dye mixed solution is heated, and a non-woven fabric is obtained to obtain a non-woven fabric. Referring to step 330, the cloth can be used for various purposes, such as anti-ultraviolet clothing, pants, caps, umbrellas, masks, tents, etc. Absorbs UV light while reducing UV exposure. Fabrics can be selected, for example, from Pongee and Polyester, where Pongee is softer. Polyester has a hard texture and a silver base oil on the bottom layer to enhance the opacity. Others can also be used, such as nylon cloth, oxford cloth, satin cloth, PVC, pearl cloth, EVA and T/C cotton cloth. Various other procedures, such as dyeing, embossing, or patterning, are well understood by those of ordinary skill in the art, and therefore will not be described.

Based on the present invention, the anti-reflection layer is not coated with ultraviolet rays as in the prior art, but the fiber made of the photo-induced dye absorbs ultraviolet rays, causing a chemical change to cause a color change effect, not only to absorb ultraviolet rays, but also to cause ultraviolet rays. Protection, seen as a result of color changes, enhances consumer trust. In addition, recycled PET bottles can also be used as the above-mentioned polymer materials to achieve environmental protection. In addition, the processing temperature of the present case needs to be lower than the dissociation temperature; and when doping the polymer and the ultraviolet absorbing dye, adding a color masterbatch or a conventional plastic dye to uniformly distribute it in the polymer base material instead of using post-staining dyeing Cloth surface.

In order to consider the gas exchange rate of the mask and the absorption of ultraviolet light, it is necessary to mix the appropriate amount of dye. The fourth picture shows that by SGS, only about 10% of the ultraviolet B-band can penetrate the mask, meaning that more than 90% of the ultraviolet rays are used. The B band is filtered by the present invention.
