    • PURPOSE: A spinning custody is provided to improve the crimp manifesting property by differing the width of each slit to compose the spinneret, and to prevent the concentration of the outer force in a joining part of the slit by putting a section of the slit, the joining part, in a side part of a triangle shape among a fiber section. CONSTITUTION: The spinning custody comprises: three circular slits(1)(2)(3) internally touched an outer circumference of each end of the slits in a perfect square of the l length of one side; three slits(1)(2)(3) formed a part located at an apex of the perfect square in a circular form of the radius of (d); the width(a) of the slit(1) formed larger than the width(b) of the slits(2)(3). Therefore the difference of the cooling speed is expanded, and the crimp manifesting property is improved by expanding the difference of the shrinking rate by contacting the cooling air in a fiber part spun from thin slits(2)(3) among the melted and spun hollow fiber.
    • 目的:提供纺纱保管,以通过使每个狭缝的宽度不同以构成喷丝头来改善卷曲性能,并且通过将狭缝的一部分放置在狭缝的接合部分中的外力的集中, 在纤维部分之间的三角形的侧部中的接合部分。 规定:纺纱保管包括:三个圆形狭缝(1)(2)(3)内部以一侧的长度的正方形内部接触狭缝每端的外周; 三个狭缝(1)(2)(3)形成一个位于完美正方形顶点的部分,其形状为(d)半径圆形; 狭缝(1)的宽度(a)形成为比狭缝(2)(3)的宽度(b)大。 因此,冷却速度的差异扩大,并且通过使从熔融和纺丝的空心中的薄狭缝(2)(3)纺出的纤维部分中的冷却空气接触来扩大收缩率的差异,从而提高卷曲性能。 纤维。

    • PURPOSE: A spinneret for a hollow fiber production is provided to improve the hollow rate, and to prevent the crush of a hollow unit by a drawing by making a slit form of the spinneret in an oval. CONSTITUTION: An oval shaped slit(1) and an oval shaped slit(2) of the spinning custody is faced each other in the left and the right sides; and a shows the inside diameter of slits(1)(2); a b shows the outside diameter of slits(1)(2); a c shows the length of the extended parts(1')(2') of slits(1)(2) added to escape the point of contact of slits; a d shows the interval of slits(1)(2); an e shows the thickness of slits(1)(2); when the c is 0, two slits are formed one perfect circle; the section of a hollow fiber formed according to grow large the value of the c is changed in an oval again by passing from the oval to a circle; when the value of the c is over the value of the a, each slit is formed a section of a 8 character type having two hollows.
    • 目的:提供中空纤维生产的喷丝头,以提高中空率,并通过将喷丝板的狭缝形式制成椭圆形来防止中空单元的挤压。 构成:旋转保管的椭圆形狭缝(1)和椭圆形狭缝(2)在左侧和右侧彼此面对; a表示狭缝(1)(2)的内径; a表示狭缝(1)(2)的外径; c示出了为了避开狭缝的接触点而添加的狭缝(1)(2)的延伸部分(1')(2')的长度; a d表示缝隙(1)(2)的间隔; e表示狭缝(1)(2)的厚度; 当c为0时,两个狭缝形成一个正圆; 根据c值越来越大而形成的中空纤维的截面通过从椭圆形向圆形再次变成椭圆形; 当c的值超过a的值时,每个狭缝形成具有两个空洞的8字符型的部分。
