▎ 摘　　要

NOVELTY - Preparing multifunctional graphene yarn comprises (1) preparing graphene functional fibers, (2) making graphene functional yarns from the graphene functional fibers, (3) preparing many functional sizing materials, (4) placing the graphene functional yarn on the creel of the yarn coating equipment, and many bobbins are made into warp beams, (5) transporting the yarn through the warp beam into a number of size tanks sequentially equipped with different functional sizes for dipping and coating, (6) sending the dipped and coated yarn into an oven for drying, (7) collecting the dried yarn on the bobbin creel for bobbin making, and (8) packaging the graphene multifunctional yarn finished product. USE - The method is useful for preparing multifunctional graphene yarn. ADVANTAGE - The multifunctional graphene yarn: has antibacterial, anti-ultraviolet, far infrared function, and anti-cutting and flame retardant function. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a multifunctional graphene yarn.
