PROTECTIVE MASKS WITH COATING COMPRISING DIFFERENT ELECTROSPUN FIBERS INTERWEAVED WITH EACH OTHER, FORMULATIONS FORMING THE SAME, AND METHOD OF PRODUCING THEREOF

摘要

The present invention provides a protective mask comprising an ultrafine fibrous coating comprising partially gelled submicron fibers interweaved with nanofibers and a biocide encapsulated in, surface-attached onto, blended with, physically trapped, and/or chemically linked to said submicron fibers and nanofibers. In an example, a microfibrous substrate with the coating assembles with other microfibrous substrates to form a protective mask having N95 level of protection and bacteria-killing capability.

1. A protective mask comprising an ultrafine fibrous coating on a first microfibrous substrate, said ultrafine fibrous coating comprising:
partially gelled submicron fibers interweaved with nanofibers; and a biocide which is encapsulated into, surface-attached onto, blended with, physically trapped, and/or chemically linked to said submicron fibers and nanofibers.
