▎ 摘　　要

NOVELTY - A graphene antibacterial fiber having dual-layer composite structure comprises fabric framework layer comprising high melting point polymer and antibacterial layer comprising graphene nanocomposite. The graphene nanocomposite is loaded in situ on the fabric framework layer with hot gas flow as carrier during the spinning process. USE - Graphene antibacterial fiber. ADVANTAGE - The graphene antibacterial fiber has high safety, excellent antibacterial effect, and stable and long-term antibacterial performance. The preparation process is simple and efficient, and reduces energy consumption and improves the process controllability and continuity. The environmentally-friendly process produces products with excellent consistency and stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene antibacterial fiber, which involves using hot gas to form hot gas stream containing graphene nanocomposition and melting polymer masterbatch to obtain a polymer melt.
