▎ 摘　　要

NOVELTY - Preparing graphene magnetic fiber comprises (i) taking graphene powder, magnetic powder, and auxiliary agent, (ii) preparing graphene magnetic particles, (iii) preparing graphene magnetic fiber master batch or slurry, and (iv) melting-spinning composite masterbatch obtained in the step (iii), or spinning the mixed slurry obtained in the step (iii) through solution spinning to obtain graphene magnetic fibers. USE - The fiber is useful for physical therapy, health care and other fields. ADVANTAGE - The fiber: has excellent magnetic properties, and antibacterial and far-infrared heating functions; improves human microcirculation; and makes the human body feel comfortable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene magnetic fiber prepared by above mentioned method.
