If you are looking for ways to reduce your carbon footprint and also find yourself making multiple trips to the dry cleaner, this self-cleaning cashmere is a fabric you might want to invest in for the future. Researchers from City University at Hong Kong's School of Energy and Environment have been developing self-cleaning fabrics since 2002. Their strain of cashmere doesn't merely repel stains, it makes them disappear using an extremely thin coating of invisible anatase titanium dioxide. When placed in sunlight for 24 hours, a chemical reaction takes place, getting rid of bacteria, dirt and stains.
Assuming the new self-cleaning cashmere material is safe, researchers hope their new technology will be integrated into clothing soon. Thus far, the clothing has tested to be safe to wear.
