摘要
首先推导了纺丝动力学数学模型及多叶形纤维截面形变动力学模型,并将两者相结合,建立了多叶形纤维纺丝成形模型.在此基础上,进行实验确定了各种不同形状时的形状系数,通过计算机数值模拟计算出多叶形纤维纺丝时的速度、温度、应力、异形度沿纺程变化情况.最后进行了多叶形纤维的产品开发实验研究.
Firstly, spinning dynamic model and deformation dynamics model of multilobal fiber section were derived, then they were combined to describe the forming process of multilobal fibers. Secondly, the shape factors to different shapes were defined by experiment. The changes of the spinning speed, temperature, stress, degree of profile along spinline were got by numerical computing and the relative product was developed.
