Researches at the Imperial College in London have developed a reusable fabric that can be taken off and re-worn:
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 fibres are 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.
The fabric, which dries when it meets the skin, is very cold when it is sprayed on, a limitation that may frustrate hopes for spray-on trousers and other garments.
The researchers hope that the technology can be adapted to create spray-on bandages, among other applications. You can view a video of the creation process at the link.
