  • Patent number: 9360612
    Abstract: The present invention relates to a light-emitting fabric, in which acrylic optical fibers and general fibers are woven together, and light is emitted to the surface of the fabric through the optical fibers floating on the surface of the union fabric. According to the present invention, part of the clad portion of the optical fibers is removed by melting so as to prevent the total reflection of the clad portion and to emit high-brightness patterns or characters having a higher brightness than those emitted by optical fibers having a conventional clad portion. Also, a semi-circular core portion is flattened so as to prevent the light from being refracted unnecessarily, and thus the high-brightness light-emitting fabric which can express complex patterns or characters at a higher resolution without emitting environmental pollutants can be provided.
