A spray-on T-shirt was demonstrated by a Spanish fashion designer in advance of the Science in Style show at Imperial College, London this week, according to an article in the Guardian.
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 experience did not appear to be too uncomfortable, judging by the expression of gum-chewing indifference on the face of the male model in the video, although the manufacturer says that the fabric, which dries when it meets the skin, is very cold when it is sprayed on.
