A new fabric that whisks out sweat and remains completely dry has been developed by US scientists using microfluidic technology. The new fabric works like human skin, forming excess sweat into droplets that drain away by themselves, said inventor Tingrui Pan, professor of biomedical engineering at the University of California, Davis. Workout enthusiasts, athletes and clothing manufacturers are all interested in fabrics that remove sweat and let the skin breathe. Cotton fibres, for example, wick away sweat but during heavy exercise, cotton can get soaked, making it clingy and uncomfortable. Researchers Siyuan Xing and Jia Jiang developed a new textile microfluidic platform using hydrophilic (water-attracting) threads stitched into a highly water-repellent fabric.
