▎ 摘　　要

NOVELTY - A nylon fiber comprises a fiber main portion having a circular cross-section, hollow cavity having a circular cross-section provided with a graphene conductive fiber and aramid fibers, and an antistatic coating and a flame-retardant fiber layer in order on outer surface of the fiber main portion. The aramid yarn is uniformly distributed on the periphery of the graphene conductive fiber. USE - Halogen-free flame-retardant nylon fiber (claimed). ADVANTAGE - The halogen-free flame-retardant nylon fiber has excellent thermal insulation property and durable antistatic property, and reduces generation of static electricity friction between nylon fibers.
