    • 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.
    • 公开了一种用于制备海绵纱的喷丝头,其中岛成分供应通道在排出部分中分成多个组。 尽管岛部的数量为500以上,但使用喷丝头制备的海绵纱线可以防止其中心部分的岛部的聚集。 因此,由于可以在一个海岛线中设置500个以上的岛部,因此能够减少岛部的细度,因此,海绵状丝线对于微细纤维的制备非常有利。 此外,海岛纱线具有大大降低生产成本的优点,因为可以从一个海岛纱线生产500个或更多个微纤维。 此外,海岛纱线根据海部分与岛部分的比例和纤维的直径呈现特定的颜色,而不添加染料等显色化合物,因此可应用于光致变色纤维。
