▎ 摘　　要

NOVELTY - The method involves manufacturing the graphene oxide and performing the positive ionization of fiber selected from filament, thread, knitted fabric, fabric and nonwoven fabric. The fiber processed as the graphene oxide is reduced. The fiber is washed and dried (S15). The fiber is restored after reducing fiber processed as graphene oxide. The fiber is processed by the quaternary ammonium salt or the cationoid reagent. The graphene is processed (S14) after feeding graphene oxide in the fiber. The charged fiber is prepared. USE - Manufacturing method of fiber for electrical conducting material, electromagneic wave shielding material and solar cell. ADVANTAGE - The graphene can be processed effectively. The electric conductance, deorderising and antibacterial effect of the fiber are improved. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the manufacturing process of the fiber.
