异形截面纤维集合体、纤维结构体及聚合物复合纤维
摘要：
本发明提供一种异型截面纤维集合体，单纤维横截面为多叶形状，并且长丝因子K1为1.5～8，K根据以下通式确定：K1=N1〔2(R1-r1)+π(R1+ r1)/α1＋(β1-α1)πr1〕/180〔D1/（ρ110000π）〕^0.52π，其中α1为异形截面叶片的角度，β1为叶片间的角度，R1为叶片外端部的外接圆的半径，r1为叶片内端部的外接圆的半径，N1为叶片的个数，D1为单纤维纤度，ρ1为纤维集合体的密度。本发明多叶形状异型截面的纤维集合体，具有良好的吸水速干性能和强伸度积，衣料用前景广阔。
摘要（英）：

The invention provides a special-shaped cross-section fiber assembly. The cross sections of signal fibers are multi-leaf-shaped. The long filament factor K1 is 1.5 to 8. K is determined by the following general formula: (b) K1 is equal to N1 [2(R1-r1) plus (R1+r1)/Alfa1 plus (Beta-Alfa1) Pi*r1]/180[D1/ Rho 11000pi)] caret (0.5)2Pi. Alfa 1 is an angle of each special-shaped cross-section blade. Beta 1 is an angle between blades. R1 is the radius of a circumcircle at the outer end part of each blade, and r1 represents the radius of a circumcircle at the inner end part of each blade. N1 is the number of blades. D1 is the fineness of signal fibers, and Rho 1 is the density of the fiber assembly. The multi-leaf-shaped special-shaped cross-section fiber assembly provided by the invention has fine water absorption and quick-drying performance and high elongation and has a bright prospect of clothing.
