A fibre optic fabric is a textile that can be illuminated by inducing a light source on one end of the fibre. As it is made of optical fibre, it can functions as a waveguide, or “light pipe” to transmit light on the surface between the two ends of the fiber.
Black luminous textile. This black fiber optic fabric is a cool and unique way to add some shine to your e-textiles project. There are optical fibers actually woven into this piece of fabric! Simply shine a bright light into the fiber bundle, which is collected at one end, and the fabric fills with little shining pinpoints. You can make the fabric nearly glow with a little bit of abrasion, just rough it up with fine sandpaper to damage the fiber and make it “leak” light. Selective abrasion is a great way to make a pattern!
