    • The present invention relates to a multi-divisional hollow fiber, a spinning nozzle including a slit for forming a multi-divisional hollow fiber, and a method for preparing a multi-divisional hollow fiber using same. According to the multi-divisional hollow fiber of the present invention, a hollow inside a hollow fiber made of a thermoplastic polymeric resin is divided into two or more, and thus, a hollow section is not easily distorted or deformed by external force in spite of a high hollowness of 3-50%, thereby maintaining the lightness and voluminosity and realizing high rightness, high insulation (thermal insulation), high elasticity, and high durability, when compared with existing hollow fibers. Further, according to the present invention, a slit which is optimized in order to provide a multi-divisional hollow fiber is designed, and then used to produce the multi-divisional hollow fiber into long fibers, short fiber, or non-woven fabrics, through a high-rate or low-rate stretching process. Thus, the prepared multi-divisional hollow fiber is useful as fiber materials for industrial construction, such as an insulating material; fiber materials for living, such as bedding for warmth and cushion, sofa, and interior materials; and fiber materials for light and warm clothing, such as leisure and sports clothing; and fiber materials for industry for the purposes of lightness, warmth, insulation, and cushion, of interior and exterior.
    • 本发明涉及一种多分割中空纤维,包括用于形成多分中空纤维的狭缝的纺丝喷嘴,以及使用它的多分中空纤维的制备方法。 根据本发明的多分段中空纤维,由热塑性聚合物树脂制成的中空纤维内部的中空分为两个或更多个,因此中空部分不容易由于外力而变形或变形,尽管 与现有的中空纤维相比,具有3-50%的高空心度,从而保持亮度和体积,并且实现高正确性,高绝缘性(高绝缘性),高弹性和高耐久性。 此外,根据本发明,设计为了提供多分中空纤维而优化的狭缝,然后用于将多分中空纤维制成长纤维,短纤维或无纺布, 通过高速率或低速拉伸过程。 因此,制备的多分段中空纤维可用作工业建筑用纤维材料,例如绝缘材料; 用于生活的纤维材料,如温暖和坐垫,沙发和室内材料的床上用品; 和轻质,暖色的纤维材料,如休闲运动服装; 和用于工业的纤维材料,用于内部和外部的轻便,温暖,绝缘和缓冲。

    • The present invention has the purpose to provide a method and an apparatus for manufacturing a conjugated fiber, which are able to manufacture a conjugated fiber capable of composing fibers with different characteristics to continuously cross in the length direction of the fibers by continuously crossing and ejecting resins having different characteristics from each other, for instance, resins with the same or different components containing functional pigments or materials, without cutting by operating a spinning nozzle unit in the melting state, and, therefore, having various surface effects and patterns in the length direction of the fiber, and a conjugated fiber manufactured thereby. According to the present invention, a conjugated fiber formed by continuously crossing different resins having different characteristics in the length direction of fibers is manufactured by supplying resins having different characteristics to a spinning nozzle unit through separate melting extruders, and continuously crossing and ejecting each melting resin supplied from each melting extruder, from the spinning nozzle unit. Also, the spinning nozzle unit comprises a spinning nozzle body equipped with multiple entrance paths, where melting resins supplied from each melting extruder are entered, and a nozzle path for ejecting melting resins; and an operator equipped with multiple connection paths for connecting each entrance path to the nozzle path, and operating so that each connection path continuously connects to the nozzle path in an alternate manner.
