[0002] Anti-counterfeiting paper is a specialty paper made using special processes and techniques. It not only effectively protects the integrity and authenticity of goods, preventing consumers from purchasing counterfeit and substandard products, but also safeguards the legitimate rights and interests of creators, preventing piracy and copyright infringement. Furthermore, the use of anti-counterfeiting paper ensures the authenticity and validity of various bills, certificates, and documents, preventing counterfeiting and misuse.

[0003] Existing anti-counterfeiting paper uses relatively simple anti-counterfeiting technologies, such as adding single elements like watermarks and security threads. While these elements can enhance the paper's security to a certain extent, their simple structure makes them susceptible to duplication and counterfeiting by criminals through technical means. Therefore, a new magnetic fiber anti-counterfeiting paper with dual security features has been proposed. Utility Model Content

[0022] In this embodiment, specifically: the first polymer protective film 131 and the second polymer protective film 133 are respectively attached to the lower surface and the upper surface of the magnetic fiber embedding layer 132. The first polymer protective film 131 and the second polymer protective film 133 cover the magnetic fiber embedding layer 132 to prevent the external environment from affecting the properties of the magnetic fiber.

[0023] In this embodiment, specifically: a number of micropores 162 are opened on the upper surface of the fluorescent fiber embedding layer 161. The micropores 162 are tiny holes formed by micro-processing the surface of the fluorescent fiber embedding layer 161 using a high-energy density laser beam. The micropores 162 have precise shape, size and position, and are evenly distributed, forming a unique anti-counterfeiting pattern. The array of micropores 162 formed by laser engraving has a higher anti-counterfeiting effect, which can not only provide a visual anti-counterfeiting mark, but also can be verified by scanning and other methods to ensure the authenticity of the product.

[0024] In this embodiment, specifically: magnetic fibers are densely distributed inside the magnetic fiber embedded layer 132 , and the magnetic fibers are evenly distributed inside the base material of the magnetic fiber embedded layer 132 through a coating process. After drying and curing, the magnetic fiber embedded layer 132 is formed.

[0025] In this embodiment, specifically: fluorescent fibers are densely distributed inside the fluorescent fiber embedding layer 161 . The fluorescent fibers are evenly distributed inside the base material of the fluorescent fiber embedding layer 161 through a coating process. After drying and curing, the fluorescent fiber embedding layer 161 is formed.

[0026] In this embodiment, specifically: the magnetic fibers of the magnetic fiber embedding layer 132 are barium ferrite magnetic fibers. The magnetic fiber anti-counterfeiting layer of the barium ferrite material combines the magnetism of barium ferrite and the morphological advantages of the fiber to form a unique and difficult-to-copy anti-counterfeiting mark. The magnetic fibers in the paper can be detected by a magnetic detection instrument, and their arrangement and magnetic strength can be verified to determine the authenticity of the paper.

[0027] In this embodiment, specifically: the fluorescent fiber of the fluorescent fiber embedded layer 161 is a rare earth aluminate fluorescent fiber. The fluorescent fiber is based on spinning raw materials and uses rare earth aluminate as the luminescent material. It has the flexibility and strength of ordinary fibers and can emit fluorescence under ultraviolet light. The rare earth aluminate fluorescent material has good environmental performance and stability and will not cause pollution to the environment.

[0028] In this embodiment, specifically: the first polymer protective film 131 and the second polymer protective film 133 are polylactic acid protective films. The first polymer protective film 131 and the second polymer protective film 133 protect the internal magnetic fiber embedding layer 132, preventing the magnetic fibers in the magnetic fiber embedding layer 132 from oxidation or corrosion during long-term use, resulting in failure of the magnetic fibers, thereby improving the service life of the magnetic fiber embedding layer 132. The polylactic acid material has good mechanical properties and is easy to process and shape, which can meet the material performance requirements of anti-counterfeiting paper.

[0029] Working principle or structural principle: By setting up a magnetic fiber embedded layer 132, the anti-counterfeiting paper can be identified by a magnetic metal identifier or magnetic induction device. At the same time, a fluorescent fiber embedded layer 161 is set up, so that the anti-counterfeiting paper can be verified for anti-counterfeiting under ultraviolet light. The microstructure array design of the micropores 162 on the surface of the fluorescent fiber embedded layer 161 can help improve the anti-counterfeiting effect. The double anti-counterfeiting design can effectively prevent forgery and copying, and improve the security and reliability of the anti-counterfeiting paper.
