NOVELTY - Graphene far-infrared fiber comprises self-made far-infrared filler and polyethylene terephthalate through melt spinning. The self-made far infrared filler comprises nano graphene, deionized water and modified self-made mesoporous seaweed charcoal. The modified self-made mesoporous seaweed charcoal is prepared by reacting polyvinyl alcohol, 3,4-dihydroxybenzoic acid, self-made mesoporous seaweed charcoal and catechol oxidase. The self-made mesoporous seaweed charcoal is prepared by carbonizing polytetrafluoroethylene and copper algae powder. USE - Graphene far-infrared fiber. ADVANTAGE - The fiber has excellent far-infrared performance and mechanical properties.
