NOVELTY - Method for preparing graphene Terylene (RTM: Polyester) fiber involves carrying out feeding step, esterification step, polycondensation step and melt spinning step. The feeding step involves adding terephthalic acid and ethylene glycol in a ratio of 1:1-2 to a reaction kettle, mixing, simultaneously adding catalyst and graphene to the reaction kettle. USE - Method is useful for preparing graphene Terylene (RTM: Polyester) fiber (claimed). ADVANTAGE - The method enables rapid and economical preparation of the graphene Terylene (RTM: Polyester) fiber with high consistency and improved fracture strength.
