▎ 摘　　要

NOVELTY - Manufacture of graphene oxide-dyed fiber involves preparing a graphene oxide dispersion, adding a cationized natural fiber to the graphene oxide dispersion by reaction to prepare a graphene oxide-dyed natural fiber, and drying the graphene oxide-dyed natural fibers. USE - Manufacture of graphene oxide-dyed fiber (claimed) used for antimicrobial cloth, bedding, and mask used in healthcare, medical, and clothing applications. ADVANTAGE - The method is simple, and enables manufacture of graphene oxide-dyed fiber with excellent antimicrobial activity, antimicrobial functionality, and coating performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene oxide-dyed fibers, which comprises graphene oxide as an active ingredient, in which graphene oxide is dyed on the surface of the fiber.
