[Last.Exile]

Efforts to create self-cleaning cotton fabrics are bearing fruit in China.

Engineers have created a chemical coating that causes cotton materials to clean themselves of stains and remove odours when exposed to sunlight.
 
 The researchers say the treatment is cheap, non-toxic and ecologically friendly.
 
 Retail experts say the innovation could prove a hit with retailers thanks to a growing demand for "functional clothing".
