Do you love the texture of cashmere but not the dry cleaning cost of keeping it clean? Hong Kong University researchers may have just come up with a solution for your fashion dilemma. The research team developed an anatase titanium dioxide-coated cashmere fabric that self-cleans when exposed to 24 hours of light. If mass-produced, not only could this technology save you money from dry cleaning, but imagine the water-saving implications it could have for the environment!
