Good news for those who hate washing socks, are worried about hygiene or resent spending money on dry cleaning: self cleaning forms of wool and silk have been developed with the help of nanotechnology.
Wool socks, skirts and silk ties may soon clean themselves of smells and stains in the sunshine, researchers in Australia and China suggest.
The secret is a nano particle coating, one already used to keep windows clear, that could lead to “self-cleaning” versions of wool and silk fabrics.
Wool and silk, which are composed of natural proteins called keratins, are among the most prized and widely used fabrics in the clothing industry. However, they are difficult to keep clean and are easily damaged by conventional cleaning agents. (link)
