摘要：A fluorescent fiber and an anti-counterfeiting material have an optical color that

varies with irradiation angles of exciting light. The anti-counterfeiting fiber includes atleast two components of materials that extend parallel along the longitudinal directionwithout twisting. At least one component contains photoluminescence material. Thedistribution of the components makes the anti-counterfeit fiber form a shieldingstructure for exciting light, and has an orientation structure. The exciting light shieldingstructure and orientation structure enable, when the anti-counterfeit fiber falls freelyinto a plane paralleled to the horizontal plane, the existence of at least two irradiationangles of exciting light above the plane paralleled to the horizontal plane, from whichexciting light irradiates on the anti-counterfeit fiber respectively. The anti-counterfeitfiber thereby displays obvious visual difference between two different luminescentcolors. In this manner, the visual characteristic of fluorescent anti-counterfeit fiber cannotbe imitated by the printing filament.
