New Zinc-embedded Nylon Fabric Successfully Inactivates COVID-19 Viruses


An international team of scientists and engineers from the University of Cambridge, the Icahn School of Medicine at Mount Sinai, ResInnova Labs and Ascend Performance Materials has found that a nylon fabric embedded with zinc ions successfully inactivated 99% of the viruses that cause COVID-19 and the common flu.

99% Reduction of Virus Particles
The researchers described how a embedded with active zinc ions adsorbed virus-containing moisture droplets and effectively inactivated the particles. The fabric produced a 2-log, or 99%, reduction of virus particles in one hour.

The research team also was able to demonstrate that nylon with active zinc ions remains stable over time, keeping its virus-inactivating properties after 50 washes.

The study shows how nylon textile fabric with zinc outperforms the widely used cotton and polypropylene materials at virus adsorption and inactivation,” Vikram Gopal, Ph.D., co-senior author and chief technology officer at Ascend Performance Materials said.

The findings have significant implications for future development of PPE, Dr. Gopal said.

Pathogen-free PPE does more than just cut down the risk of transmitting the virus,” Gopal said. “By making PPE washable and reusable, you reduce the need for single-use products, keeping hundreds of millions of masks out of landfills.”
