摘要： A manufacturing method for a transparent fiber is provided. The method includes forming a spinning solution containing a polyimide polymer in an organic solvent. The polydispersity index (PDI) of the polyimide polymer is 1.3˜2.6. The spinning solution is used to perform a dry-jet wet spinning step to form a plurality of fibers. Furthermore, the plurality of fibers are subjected to a thermal drawing step to form a plurality of transparent fibers, wherein the temperature of the thermal drawing step is controlled from 215° C. to 350° C. The manufacturing method for a transparent fiber provided in the present invention makes use of a polyimide polymer material and utilizes a dry-jet wet spinning step and a thermal drawing step, which allows the formation of a transparent and high strength polyimide fiber.
