Researches at the Imperial College in London have developed a reusable fabric that can be taken off and re-worn. Why, I have no idea, but here's how it works:
The spray consists of short fibres that are mixed into a solvent, allowing it to be sprayed from a can or high-pressure spray gun. The fibers are then mixed with polymers that bind them together to form a fabric. The texture of the fabric can be varied by using wool, linen or acrylic fibres.
Researchers hope this technology can be adapted to create spray-on bandages, among other applications. Here's a video of the process
