从纺丝动力学和纤维截面动力学基本方程出发,通过试验确定了宽长比为0.6的扁十字纤维的形状系数,在此基础上,通过将前期研究得到的宽长比为0.5的扁平纤维和宽长比为1的正十字纤维的形状系数与该扁十字纤维的形状系数进行最小二乘法拟合,得到了任意十字纤维的理论数学模型,从而可实现十字异形纤维工艺参数的理论优化和异形度可控的生产。
Based on the fundamental equations of spinning kinetics and fiber section kinetics, the shape coefficient of flat cross-shaped fiber with width-length ratio of 0.6 was determined through experiments. On the basis of this, the flat fiber with aspect ratio of 0.5 And the shape factor of the regular cross fiber with the aspect ratio of 1 and the shape coefficient of the flat cross fiber are fitted by the least square method to obtain the theoretical mathematical model of any cross fiber so that the theoretical optimization of the process parameters of the cross shaped fiber can be realized and Profile controllable production.
