If you’re wondering what materials to use to stitch together your antiviral mask, it seems it could be that you need a couple of different fabrics for it to work best – woven cotton and a piece of silk or chiffon…
Tightly woven cotton acts as a physical barrier to viral particles and droplets carrying the virus. Silk and chiffon can both build up quite a static charge and this will help trap viral particles electrostatically.
Together the materials will reduce the risk of the wearer shedding virus from nose or mouth into the environment and on to other people or surfaces that others might touch. Conversely, the mask will, to some extent reduce the risk of you inhaling viral particles from the air. The researchers say that substituting chiffon or silk for flannel or using a cotton quilt with cotton-polyester backing could be just as effective. But, Sciencebase would add that it’s not so strong a fashion statement
There is also the added benefit of wearing a facemask in that it will reduce how often you touch your nose and mouth with your filthy, disease-ridden hands. Now go and wash them thoroughly with plenty of soap and warm water for at least 20 seconds!
