The birefringent island-in-the-sea yarns of the present invention are free of aggregation of island portions in the center thereof, although the number of island portions is 500 or more. As a result, the birefringent island-in-the-sea yarns maximize an optical modulation interface area, and thus considerably improve optical modulation efficiency, as compared to conventional birefringent island-in-the-sea yarns including one spinning core. Accordingly, the birefringent island-in-the-sea yarns advantageously exhibit considerably improved luminance, as compared to conventional birefringent island-in-the-sea yarns wherein birefringent fibers or one spinning core is present in a sheet. | 08-05-2010 |

In addition, several hundred layers are not laminated on one film and the film can be easily fabricated at considerably reduced costs. Furthermore, the luminance-enhanced film has considerably more birefringent interfaces, as compared to films fabricated by conventional methods wherein birefringent fibers are incorporated into sheets, thus considerably improving luminance-enhancement effects and being industrially applicable. | 08-05-2010 |

20100205926 | SPINNERET FOR PREPARING ISLAND-IN-THE-SEA YARNS - Disclosed is a spinneret for preparing island-in-the-sea yarns, wherein island ingredient supply channels are partitioned into a plurality of groups in a discharge portion. The island-in-the-sea yarns prepared using the spinneret can prevent aggregation of island portions in the center thereof, although the number of island portions is 500 or more. Accordingly, island-in-the-sea yarns are considerably advantageous for the preparation of microfibers, since 500 or more island portions can be disposed in one island-in-the-sea yarn and fineness of island portions can thus be reduced. In addition, the island-in-the-sea yarns have an advantage of considerably reduced production costs, since 500 or more microfibers can be produced from one island-in-the-sea yarn. Furthermore, the island-in-the-sea yarns render a specific color according to the ratio of sea portions to island portions and diameter of fibers, without adding chromogenic compounds such as dyes, and are thus applicable to photochromic fibers. | 08-19-2010 |
