A new study has revealed that masks made from a combination of different fabrics such as cotton, silk, chiffon, flannel can provide 80 per cent protection against infections.

The new study obtained by an online newspaper, TheCable, shows that type of fabric and its arrangement can help improve protection against viruses, including the novel coronavirus.

The research team in America’s Argonne National Laboratory found that cotton, natural silk, and chiffon provides above 50 per cent protection against viral particles in aerosols, provided they have a tight weave.

Tightly weaved layers of cotton, the most widely used material for cloth masks, “could provide over 79 per cent depending on particle size while a combination of different fabrics such as cotton silk, chiffon, flannel can provide 80 per cent filtration coverage.”

The report, titled: “Aerosol Filtration Efficiency of Common Fabrics Used in Respiratory Cloth Masks” has been published by the American Chemical Society.

The report added that cotton quilt laced with batting provides the best protection at 96 per cent because of the “fibrous nature of the batting aids in the superior performance at small particle sizes.”

Earlier, researchers at Netherland’s National Institute for Public Health and the Environment and Public Health England (PHE) had found that in the event of surgical mask shortage, these masks are better than no mask at all.

“Any type of general mask use is likely to decrease viral exposure and infection risk on a population level,” the Netherland report had said.
