BACKGROUND AND OBJECTIVE The air-flow field of the air centrifugal spinning is simulated and measured. The simulated air velocities coincide well with the measured ones, confirming the correctness of the air-flow field model. METHODS The polymer drawing in the air-flow field of the air centrifugal spinning is modeled and simulated. Effects of the rotation speed and initial air velocity on the diameter and radius vector of the threadline are investigated. RESULTS The air velocity is found to decrease with the increase of the distance away from the nozzle exit. Simulation results show that both larger rotation speed and higher initial air velocity can reduce the threadline diameter. CONCLUSION The radius vector of the threadline increases rapidly with the increase of the initial air velocity, which is helpful to reduce the threadline diameter.

探索空气离心纺丝的聚合物图纸。

背景与目的模拟并测量了空气离心纺丝的气流场。模拟的风速与测得的风速吻合得很好，证实了气流场模型的正确性。方法对空气离心纺丝的气流场中的聚合物拉伸进行建模和模拟。研究了转速和初始风速对螺纹直径和半径矢量的影响。结果发现，随着远离喷嘴出口的距离的增加，空气速度降低。仿真结果表明，较大的转速和较高的初始风速均可减小螺纹直径。结论随着初始风速的增加，线的半径矢量迅速增大，这有助于减小线的直径。
