▎ 摘　　要

NOVELTY - A three-layer structure dustproof net comprises a fabric (f1), a nanofiber web, and a fabric (f2) in order. The fabric (f2) is obtained by weaving graphene fibers in a hexagonal net shape. USE - Three-layer structure dustproof net used for blocking external contaminants e.g. fine dust, ultrafine dust, and yellow dust, and pests e.g. mosquitoes and flies. ADVANTAGE - The three-layer structure dustproof net has excellent dust collection efficiency, oxygen permeability and antibacterial properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the three-layer structure dustproof net, which involves preparing the fabric (f1), forming a nanofiber web by electrospinning a polymer solution on one side of the prepared fabric (f1) and laminating the fabric (f2) on one side of the nanofiber web.
