▎ 摘  要

NOVELTY - Method for preparing composite layer mask material composed of three-layer structure of composite nonwoven fabric, nanofiber membrane and composite nonwoven fabric, is claimed, where the composite nonwoven fabric is polypropylene meltblown nonwoven fabric, and the nanofiber membrane is obtained by spinning a spinning solution using an electrostatic spinning method. USE - The method is useful for preparing a composite layer mask material. ADVANTAGE - The mask material has relatively uniform pore size distribution, small average pore size, and excellent filtering effect.
