BRIGHTNESS-ENHANCING FILM

摘要

The present invention relates to a brightness-enhancing film, and more particularly, to a brightness-enhancing film that reduces pilling by preventing fiber breakage of birefringent sea island fiber. The thus-manufactured brightness-enhancing film is not prone to the entanglement of birefringent sea island fibers (monofilament) and to the formation of fiber stripes, and therefore has improved visibility. Also, when birefringent sea island fibers are not subjected to a separate fiber-combining process or are combined, only a few thick fiber strands may be combined to prevent a portion of the fibers from being broken and the occurrence of pilling.
