Nanofiber air filtering nonwoven material for face masks
Nanofibers allow breathing air, but block the virus
Air anti-aerosol filter fabric for respiratory protection from viruses from polymer nano-fibers, "Cocoon" series.
In fact, it is a membrane that allows air and vapor to pass through, but does not allow viruses and bacteria and aerosol to pass through. The sandwich structure with thick fibers on the outside and ultra-fine fibers on the inside provides a fabric strength with ultrafine filtration of 98% at 60 nm, and more than 99.5% at larger particles. The combination of hydrophilic and hydrophobic polymers disperses the vapor from breathing and provides low breathing resistance during the entire wearing period.
Biodegradable and hypo-allergenic PLA polymer fibers does not irritate the skin and is safe for fiber to enter the lungs. The coating of the fibers from copper ions and polyelectrolytes, which increases the surface negative charge of the polymer, of the nano-fiber destroys the envelopes of the virus and immobilizes them. The surface of cells is also negatively charged, a positively charged virus is attracted to it, as well as attracted to fibers.
Mainly the design of our mask will be different at the nano level, in the world of viruses
