Sydney: During the Covid-19 pandemic, cloth face masks became a way to help protect from the virus. For some people, they became a fashion statement, with many fabric choices available. But just how effective are they, especially in blocking respiratory droplets from a sneeze?
Researchers from the University of New South Wales used high-speed videos of a person sneezing to identify the optimal cloth mask design. The team made simple face masks with 17 commonly available fabrics. Each mask had one, two or three layers of the same or different fabrics.
