New Nanotech Fabric Never Gets Wet

holy_calamity writes "New Scientist reports on a simple coating for polyester that renders it unwettable — even after two months underwater it emerges dry to the touch. Water cannot attach to the new fabric thanks to nanostructured filaments and a structure that traps a constant air layer. One potential use is for low-drag swim wear."

If you can get it dirty, this may yet be the case of a cloth that is machine washable and comes out dry from the machine. Or better yet, washes out simply by brushing off the stain with the back of the hand.
