Method for producing high-brightness light-emitting fabric using acrylic optical fibers, and high-brightness light-emitting fabric

摘要

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.

主权项

1. A method for producing a high brightness light emitting fabric using acrylic optical fibers, comprising:
a weaving process for producing a fabric by weaving an acrylic optical fiber formed of a clad part and a core part, and a general fiber; and a heat treatment process for melting a partial cross section of the clad part of the acrylic optical fiber protruding from a surface of the fabric by heat-treating the fabric while pressurizing with a roller or a press of 100˜250° C. and flattening and exposing the core part, wherein in the heat treatment process the diameter of the exposed core part of the acrylic optical fibers is 20˜80% of the diameter of the whole acrylic optical fibers.
