NOVELTY - Preparing graphene composite anion polyester fiber involves adding aqueous solution of graphene oxide, the aqueous solution of trimethylmethylcyclopentadiene platinum, and the POOS-Samarium compound to the aqueous ethanol solution, stirring at 60 degrees C for 12-24 hours to obtain a composite spinning solution, spinning the composite. The liquid is wet-spun by a wet-spinning machine, and hot air is used to remove ethanol to obtain fiber one, immersed the fiber obtained in an aqueous glucose solution for 6-8 hours, taken out, washed three times with deionized water, and dried to obtain fiber two, placed the fiber 2 obtained in a high-temperature furnace, raised the temperature to 600 degrees C under the protection of nitrogen, taken out after holding for 3-5 hours, washed with deionized water 3 times, and dried to obtain fiber three, treated fiber with polyester fiber to obtain graphene composite anion polyester fiber. USE - Method for preparing graphene composite anion polyester fiber. ADVANTAGE - The method enables to prepare graphene composite anion polyester fiber has good health care function to human body.
