▎ 摘　　要

NOVELTY - The filter bag has a bag unit formed with a dust-collecting layer (111), a middle layer (112) and a base cloth layer (113). A mesh layer is formed between the middle layer and the cloth layer and provided with a warp (114) and a weft. The warp and the weft are interlacing woven into a net. The warp is formed by graphene fiber. The weft is formed by polyurethane elastic fiber by realizing twisting process. The weft is provided with a strip-shaped lining plate (20). The strip-shaped lining plate is formed as a hollow structure and contained with negative ion powder (21). USE - Graphene modified filter bag for containing filtering material (claimed) for a domestic air purifier. ADVANTAGE - The filter bag makes the mesh layer to increases flexibility of the bag unit and bag unit surface shape recoverability after occurring of wrinkles during filtering process. The frame supports the filter bag to prevent the filter bag from collapsing. The filter bag effectively inhibits bacteria during cleaning process to ensure safety performance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene modified filter bag.
