NOVELTY - Preparation of headrest multifunctional graphene composite fiber comprises subjecting polyester fiber to coarse and finishing treatment to obtain roughened polyester fiber; dissolving composite polyethylene glycol with phase transition temperature of 20-30 degrees C in ethanol to obtain composite polyethylene glycol solution, adding roughened polyester fiber, stirring and soaking for 2-4 hours, and filtering to obtain composite polyethylene glycol-polyester fiber; and adding succinic acid acyl peroxide into deionized water to obtain succinic acid acyl peroxide solution, adding graphene oxide, ultrasonically dispersing, filtering to obtain carboxylated graphene oxide, adding to deionized water to obtain carboxylated graphene oxide suspension, adding composite polyethylene glycol-polyester fiber, ultrasonically dispersing, filtering, and drying. USE - The method is for preparation of headrest multifunctional graphene composite fiber. ADVANTAGE - The graphene composite fiber surface contains a large amount of hydrophilic group, good hygroscopicity, using graphene composite fiber filled with the heat of the pillow is reduced, and the comfort of the pillow is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a headrest multifunctional graphene composite fiber.
