Southeast University of Nanjing Develops Self-Cleaning Fabric to Reduce Detergent Use and Environmental Impact
Researchers at Southeast University of Nanjing have developed a textile coating that significantly reduces the need for detergent in laundry, potentially transforming a common household activity with substantial environmental impact. The innovation involves a polymer-based coating applied to fabrics, creating a surface that prevents dirt from adhering. This coating also forms a hydration layer that acts as a barrier against stains, functioning effectively under various light conditions. Tests have shown its effectiveness on materials like cotton, silk, and polyester, indicating its versatility. The new system simplifies the washing process by eliminating the need for detergent and reducing washing to a simple rinse, thereby decreasing water, energy, and time usage by 82%. The coating is also highly resistant, maintaining its effectiveness after multiple uses.
