The one-layer mask was manufactured from a folded cotton T-shirt and the double-layer mask was manufactured making use of the stitching system recommended by the U.S. Facilities for Illness Regulate and Avoidance.

The conclusions were being posted on the net July 23 in the journal Thorax.

“Guidelines on residence-manufactured cloth masks ought to stipulate various levels,” the scientists concluded. “There is a need for extra proof to notify safer cloth mask style, and nations ought to ensure sufficient manufacturing or procurement of surgical masks.”
