▎ 摘　　要

NOVELTY - A composite material comprises feather and graphene material-modified staple fiber uniformly dispersed in the feather. USE - Composite material is useful in thermal insulation material (claimed). ADVANTAGE - The composite material has excellent antibacterial property, far-infrared resistance, antistatic property and thermal performance, can neutralize static electricity generated by the feather due to friction, and improves reunification. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite material, which involves blowing the graphene material-modified staple fiber into filament shape using stepped air flow rate and mixing the filament-shaped graphene material-modified staple fiber with feather.
