The Indian Institute of Technology, Bombay (IIT-B) has developed a wash-resistant antiviral and antibacterial coating for textiles to be used in masks. They have also filed two patents related to this technology.
The technology, known as Duraprot, the coating crosslinks both antibacterial and antiviral elements onto the fibres of the textile. A simple dipping process is used to make this work. This coating is maintained after many wash cycles and has been examined at least for 20 wash cycles. This is mandatory as per textile guidelines.
Rinti Banerjee, who is the Madhuri Sinha chair at the Department of Biosciences and Bioengineering in IIT-B, said there was an urgent need for personal protective equipment, including two- and three-ply masks, N95 masks and gowns, for healthcare workers.
“And this requires increasing the effectiveness of two and three-ply masks with antibacterial and antiviral properties. The coating materials are low cost and the idea is to develop and scale up masks with antiviral activities at an affordable cost,” Banerjee said.
Currently Duraprot Technology is licensed to Meemansa, a Mumbai-based textile and garment manufacturing company. Meemansa founder Priyanka Bapna says, “We have sent the coated cloth to the external testing agency for validation. We are expecting the result in the middle of next week after which we will start the process of applying it on masks. ”
