▎ 摘　　要

NOVELTY - The core has a filter core main body provided with an outer non-woven fabric layer (1), a graphene active carbon fiber layer (2), a biologicalenzyme filter cotton layer (3), an absorbent cotton layer (4) and a non-woven fabric layer (5). The filter core main body is fixed with a sealing ring (6), where the sealing ring is made of synthetic rubber. USE - Graphene protective respirator filter core. ADVANTAGE - The core uses the active carbon fiber loaded with graphene, improve primary filtering effect of bacteria, avoids that the breathing steam is condensed on graphene active carbon fiber layer and the biological enzyme filter cotton layer, and improves filtering effect of the mask. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing graphene protective respirator filter core. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene protective respirator filter core.
