Current water-intensive practices for dyeing silk involve harsh toxic chemicals that can poison workers and the environment, but a group of scientists have created a method that could eliminate the dyeing process all together. Researchers from the Institute of Materials Research and Engineering (IMRE) in Singapore found that by feeding silkworms a diet of mulberry leaves mixed with dye, the little buggers produce naturally colored silk. Not only is the method eco-friendly, but it drastically reduces the amount of water needed.
