After analyzing various types of masks under a microscope, scientists have identified which of them are best protected from COVID-19. This is reported by Science News.
Studies have shown that respiratory masks N95 are most effective for protection against coronavirus. Effectively capture the particles of the virus are also flannel masks, which will not say about masks of synthetic tissues, for example, from chiffon or viscose.
According to a microanalyz specialist from the Smithsonian Institute for Nature Protection, Edward Vicenza, the chaotic nature of cotton fibers with their wrinkled texture and a complex shape with bends and folds, probably allows cotton to capture more nanoscale particles than other fabrics.
“Cotton” loves “water and swells in a wet environment. Therefore, the particles get harder to penetrate the mask,” says the scientist.
According to him, polyester fabrics (polyester) have well-organized, straight and smooth fibers, which makes them less efficient materials for face masks.
