Abstract: The present invention relates to a multi-divisional hollow nozzle, a method for preparing a multi-divisional hollow fiber using the same, a multi-divisional hollow fiber obtained from the method, and a use of the multi-divisional hollow fiber. According to the present invention, a multi-divisional hollow nozzle having at least two hollows per hole is designed by providing at least two slits for forming a multi-divisional hollow fiber, thereby dividing a hollow inside a hollow fiber made of a thermoplastic polymeric resin into two or more, and thus providing a multi-divisional hollow fiber of which 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 lightness, high insulation (thermal insulation), high elasticity, and high durability, when compared with existing hollow fibers. Further, the 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; 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 materials for transportation, such as an automobile, an aircraft, and a train.

Abstract: The present invention relates to a non-round cross-sectional and multi-divisional spinning nozzle, a non-round cross-sectional and multi-divisional hollow fiber manufactured thereby and use thereof. The non-round cross-sectional and multi-divisional spinning nozzle is designed so that a hollow fiber has three or more hollows at the inner side thereof and the outer side of the fiber is divided into the same number as the number of dividing the inner side of the fiber to form a non-round cross section. The non-round cross-sectional and multi-divisional hollow fiber manufactured by the non-round cross-sectional and multi-divisional spinning nozzle maintains light weight and volume and maximizes quick sweat absorbency and high-speed drying by adding not only the intrinsic property of the hollow fiber but also a non-round cross-sectional shape and surface corrugation on the non-round cross section because the hollow cross-section is not distorted or deformed easily by an external force despite high hollowness. Using the lightness insulation and quick sweat absorbency and high-speed drying properties of the non-round cross-sectional and multi-divisional hollow fiber, the non-round cross-sectional and multi-divisional hollow fiber is useful for a light and insulating fabric material for leisure and sports; a fabric material for everyday life such as bedclothes for insulation and cushion, sofas and interior decoration; an insulating material for industrial buildings; and interior and exterior materials for transport such as vehicles, airplanes and trains.
