  A high-luminance light-storing fiber is provided. A modified light-storing powder and a dispersing agent are added to a polyester material, and then prepared by kneading, granulating and spinning to obtain the light-storing fiber having fiber fineness of 1-10 dpf. The fiber luminance satisfies the following conditions: (1) after irradiation with a D65 light source at 2001 ux for 20 minutes, the initial luminance can reach 150 mcd/m2 or more; (2) after irradiation with a D65 light source at 251 ux for 25 minutes, the initial luminance can reach 50 mcd/m2 or more.
