▎ 摘  要

NOVELTY - Preparing graphene composite sound insulation filter cotton involves select various raw material in proportion to obtain graphene composite polypropylene hollow staple fiber, using graphene composite polypropylene hollow staple fiber and basic fiber to obtain spunlace non-woven fabric, using the spunlace non-woven fabric as the substrate, and compounding respectively the upper and lower sides with the melt-blown non-woven fabric to obtain the graphene composite sound insulation filter cotton. USE - Method for preparing graphene composite sound insulation filter cotton used in sound insulation field and air filtering field. ADVANTAGE - The prepared sound insulation filter cotton has excellent sound insulation effect, is relatively soft, and has excellent filtering efficiency, and can be applied to various sound insulation field, air filtration field, etc.
