Abstract:

This paper briefly introduced the classification of disposal face masks, and the composition and structure of key protective layer, in addition to its protection principle. The feasibility of reuse and disinfection of the disposable face masks with several common medical methods is discussed based on the physical structure and chemical composition of meltblown, the main protective layer, in addition to biochemical characteristics of new coronavirus.

Key words: Medical mask, SMS structure, Polypropylene electret melt blown nonwovens
