[0002] The LOGO labels on traditional clothes usually adopt printing or embroidery processes, with fixed colors and patterns, lacking changes and being difficult to meet consumers' needs for personalization and fashion. Although there are some color-changing materials on the market, their applications on clothing labels are not extensive. The main reasons are the unstable color-changing effects and short service lives. Therefore, how to provide a clothing label that not only has a color-changing effect but also maintains stability and durability has become a technical problem to be solved currently. Content of the Utility Model

[0003] The purpose of this application is to have a stable label structure, a long-lasting color-changing effect, and meet consumers' needs for personalization and fashion.

[0004] The above technical purpose of this application is achieved through the following technical solution: An ultraviolet light-changing label, which comprises a base layer, a color-changing layer, and a protective layer stacked in sequence.

[0005] By adopting the above technical solution, the color-changing layer can change color according to the ultraviolet light intensity, providing an intuitive ultraviolet index reference for users. In the presence or absence of ultraviolet light, the color change of the label forms a dynamic effect, increasing the visual richness. It helps users timely understand the ultraviolet situation of the environment they are in, reminds them to take protective measures, and reduces the risk of skin damage caused by ultraviolet rays. The unique color change endows the clothing with a sense of fashion and fun, meets consumers' needs for personalized clothing, and enhances the attractiveness of the clothing. The protective layer provides protection for the color-changing layer and improves the overall service life of the label.

[0006] Optionally, the base layer is made of a soft and durable textile material, and the textile material includes but is not limited to polyester or nylon.

[0007] By adopting the above technical solutions, the soft material enables the base layer to better fit the surface of the clothing, reducing the sense of abruptness. The durable characteristics ensure that the base layer maintains the stability of its performance and structure during long-term use. The soft base layer will not cause friction or discomfort to the skin, improving the overall comfort when wearing the clothing. The durable material makes the base layer not easily damaged, deformed or worn, thus extending the service life of the entire label. The good fit and stability contribute to maintaining the original appearance of the clothing without affecting the overall aesthetic of the clothing. It can be adapted to clothing of different materials and styles, increasing the versatility of the label. Due to its good durability, the cost of frequently replacing or repairing the label due to damage to the base layer is reduced. The comfortable wearing experience and long-lasting use effect can greatly improve the satisfaction of consumers with the clothing with such a label.

[0008] Optionally, the ultraviolet light-changing material used in the color-changing layer can restore its original color in an environment without ultraviolet light, and the ultraviolet light-changing material includes but is not limited to silver halide.

[0009] By adopting the above technical solutions, a reversible color change under the conditions of the presence and absence of ultraviolet light is achieved, showing a clear and stable change effect. It ensures that the color-changing material maintains a good ability to restore its original color during multiple color-changing cycles. The characteristics of being able to change color and restore the original color repeatedly enable the label to effectively perform its function for a long time without losing its effectiveness due to irreversible color change. No additional energy input is required to restore the original color, which conforms to the concept of energy conservation and environmental protection. It extends the service life of the color-changing material and reduces the cost of replacement or maintenance. It can accurately change and restore the color according to the presence and absence of ultraviolet light, providing reliable ultraviolet information for users. Restoring the original color when there is no ultraviolet light will not affect the overall beauty of the clothing due to the color residue of the label.

[0010] Optionally, the protective layer is made of a transparent or semi-transparent wear-resistant material, and the wear-resistant material includes but is not limited to polyurethane film.

[0011] By adopting the above technical solutions, the transparent or semi-transparent characteristics enable the color change of the color-changing layer to be clearly observed without affecting the visual effect. It provides good wear-resistant performance and reduces the damage to the color-changing layer caused by external factors. It ensures that the color-changing layer is not worn and polluted, maintaining its normal color-changing performance for a long time and extending the service life of the label. The transparent or semi-transparent material will not cover the design and pattern of the clothing itself, maintaining the overall beauty of the clothing. The wear-resistant characteristics make the label not easily damaged during daily use, washing and friction, improving the reliability of the label. Due to the good protection effect, the cost of repairing or replacing the label due to damage to the color-changing layer is reduced.

[0012] Optionally, a magic tape is provided on the base layer.

[0013] By adopting the above technical solution, the design of the Velcro enables the label to be easily fixed on or removed from the clothing. It ensures that the label is not easily detached during use and maintains a stable position. When the label needs to be washed or replaced, it can be quickly disassembled for convenient operation.

Compared with other fixing methods, the installation and disassembly process of the Velcro causes less damage to the clothing and the label.

[0014] Optionally, buttons are provided on the base layer.

[0015] By adopting the above technical solution, the buttons can provide a strong connection force to firmly fix the label on the clothing.

[0016] Traditional and classic appearance: The design of the buttons gives a traditional and classic feeling. It ensures that the label is not easily detached, especially during relatively strenuous activities. The buttons themselves can serve as a decorative element, adding details and texture to the clothing. The installation and disassembly are relatively simple and do not require special skills. Buttons usually have a long service life and are not easily damaged.

[0017] Optionally, both between the base layer and the color-changing layer and between the protective layer and the color-changing layer are tightly connected by bonding or hot pressing processes.

[0018] By adopting the above technical solution, it ensures that the layers are tightly connected and not easily separated. The force and performance distribution at the connection part are relatively uniform. The tight connection of the layers ensures the structural stability of the label during use and reduces the functional failure caused by layer separation. The good connection helps the protective layer to fully play its role and better protect the color-changing layer from external influences. The stable connection enables the color-changing layer to work properly, with accurate and uniform color changes.

[0034] The following further describes the present application in detail with reference to the accompanying drawings.

[0035] In this embodiment, referring to Figure 1 , a UV light-changing label includes a base layer 1, a color-changing layer 2 and a protective layer 3, which are sequentially stacked. The base layer 1 and the color-changing layer 2 are tightly connected by an adhesive or hot pressing process to ensure that they are not easily separated during long-term use. The protective layer 3 and the color-changing layer 2 also adopt an adhesive process to ensure the flatness and firmness of the protective layer 3.

[0036] Referring to Figure 2, the color-changing layer 2 includes a low UV index portion 21, a medium UV index indicating portion 22, and a high UV index indicating portion 23. Preferably, the same material is used for the three indicating portions to achieve the indication of different UV index ranges. A material that is sensitive to UV intensity and has a certain gradient of color change can be considered. A possible material is some photochromic materials with specific chemical compositions. For example, a photochromic material containing the following components is used: polyurethane acrylate oligomer: 50-60 parts; acrylate monomer: 30-40 parts, optionally at least one selected from the group consisting of 2-(ethoxy)ethoxyethyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, tetraethylene glycol diacrylate, and ethoxylated trimethylolpropane triacrylate, polyol: 10-12 parts; surfactant: 3-6 parts; photoinitiator: 3-5 parts; color-changing material: 1-5 parts, which can be made from 9-12 parts of amino organosilicon resin, 3-7 parts of ethyl acetate solvent, 10-12 parts of cyano-substituted stilbene-type compound (z)-cn-aphp, 3-6 parts of polyolefin polymer, 1-1.5 parts of dispersant, and 1-1.5 parts of defoamer. The preparation method is to first stir the amino organosilicon resin and ethyl acetate solvent evenly, then add the cyano-substituted stilbene-type compound (z)-cn-aphp, polyolefin polymer, dispersant, and defoamer, and stir at a high speed of 1800 r / min to 2300 r / min for 30 min to obtain a mixture. Then, the mixture is dried and ground into powder. To make the same material show obvious color change partitions at different UV indices, it may be necessary to precisely control the composition ratio of the material, the coating thickness, or adopt other auxiliary means. In practical applications, a large number of experiments may also be required to optimize and adjust to achieve the effect of presenting different and distinguishable color changes within the three UV index ranges of 0-2, 3-7, and greater than 8. Different environmental conditions (such as temperature, humidity, etc.) may also affect the color-changing effect of the material and need to be considered in actual use. In addition, the grading standard of the UV index is usually as follows: 0-2 indicates the weakest, with basically no impact on the human body; 3-4 indicates weak, with a relatively small possible impact on the human body; 5-6 indicates medium, with a medium-strength harmful impact on human skin; 7-9 indicates strong, with a greater impact on the human body, and protective measures need to be taken; greater than 10 indicates very strong, with the greatest impact on the human body, and it is best to avoid going out. When using the color-changing label, these grading standards can be referred to to judge the UV intensity.

[0037] Label manufacturing process: First, cut the base layer 1 material according to the design requirements to the desired shape and size. Then, evenly apply or spray the color-changing material on the base layer 1 to form the color-changing layer 2, and ensure that the thickness of the color-changing layer 2 is uniform. Next, cover the color-changing layer 2 with the protective layer 3 material and fix it through bonding or hot pressing. Finally, trim and tidy up the label to ensure that its edges are smooth and free of burrs.

[0038] Preferably, the base layer 1 is made of polyester material, which is soft and durable, ensuring the fit and comfort of the label with the clothing. The color-changing layer 2 uses silver halide as the ultraviolet light color-changing material. This material will change color under ultraviolet light irradiation and can restore its original color when the ultraviolet light disappears, realizing reversible color change. The protective layer 3 uses a polyurethane film, which has good abrasion resistance and can effectively protect the color-changing layer 2 from external wear.

[0039] The implementation principle is: under ultraviolet light irradiation, the silver halide material will undergo a chemical reaction, resulting in a color change. When the ultraviolet light disappears, the reaction proceeds in the reverse direction and restores the original color. Through the color change of the color-changing layer 2, the ultraviolet index outdoors where the user is located can be reflected, helping the user confirm whether timely protection against ultraviolet irradiation is needed. This characteristic of color change makes the label fashionable and interesting, meeting the needs of consumers for personalized clothing.

[0040] Example 2

[0041] Different from Example 1, the materials used for the base layer 1 in this example include but are not limited to polyester, and can be made of materials such as nylon, spandex, modal, or tencel. For example, nylon material has better abrasion resistance and wrinkle resistance and is suitable for occasions that require higher durability.

[0042] Example 3

[0043] The ultraviolet light color-changing material used for the color-changing layer 2 can restore its original color in a UV-free environment, and the ultraviolet light color-changing materials include but are not limited to silver halide. Materials such as spiropyrans, fulgides, or diarylethene can be used for spraying. For example, they have very good thermal stability, chemical stability, as well as excellent sensitivity and anti-fatigue properties.

[0044] Example 4

[0045] The protective layer 3 is made of a transparent or semi-transparent wear-resistant material, and the wear-resistant materials include but are not limited to polyurethane films. Materials such as polycarbonate, acrylic, or polymethylpentene can be used. For example, polymethylpentene is a plastic with high transparency, high heat resistance, and wear resistance.

[0046] Example 5

[0047] Refer to Figure 1, in an ultraviolet light-changing label in this embodiment, a magic tape 4 is provided on the base layer 1. Due to the adhesive property of the magic tape 4, users can easily paste the label on the clothing, and at the same time, it is convenient to replace and adjust the position.

[0048] Embodiment 6

[0049] Refer to Figure 3 , different from Embodiment 5, a button 5 is provided on the base layer 1, and the label can be fixed on the clothing through the button 5.

[0050] Embodiment 7

[0051] Refer to Figures 4-6 , different from Embodiment 1, in this embodiment, an extension 6 is provided on the base layer 1 of the label, and a protective layer 3 is provided on the extension 6. The base layer 1, the extension 6 and the protective layer 3 enclose to form an installation groove 8. A support layer 7 is laminated on the side of the color-changing layer 2 away from the protective layer 3, and the support layer 7 and the color-changing layer 2 are installed and fitted into the installation groove 8 through the notch of the installation groove 8, enhancing the three-dimensional sense of the label. At the same time, by replacing the support layer 7, it is convenient to replace the color-changing layer 2, so that the label can maintain an effective color-changing mark.

[0052] Embodiment 8

[0053] Refer to Figures 4-6 , on the basis of Embodiment 7, a handle part 9 is further provided on the support layer 7 in this embodiment. The setting of the handle part 9 facilitates users to easily pick up and replace the support layer 7 and the color-changing layer 2 thereon, improving the user experience. The remaining structures are the same as those in Embodiment 7. The handle part 9 provides a convenient holding point for users, enabling them to easily grasp and move the support layer 7.

[0054] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
