NOVELTY - Preparing graphene polyester fiber involves mixing sodium silicate solution with deionized water to uniformly prepare a precursor liquid, and adding graphene powder to precursor liquid, and then uniformly stirring the mixture to obtain graphene solution. The polyester fiber is added to the graphene solution for high-speed stirring to obtain a graphene polyester fiber solution. The obtained graphene polyester fiber solution is subjected to high temperature atomization drying treatment to obtain graphene polyester fiber. The graphene polyester fiber is subjected to fluffy treatment to obtain the desired product. USE - Method for preparing graphene polyester fiber (claimed). ADVANTAGE - The method enables to prepare graphene polyester fiber with consistent properties and improved fracture strength.
