摘　　要：通过建立PAN湿法纺丝丝条凝固过程中"皮·芯"结构模型,对PAN湿法纺丝凝固过程进行模拟结果表明,喷丝头附近的凝固浴浓度降低时,有利于提高纺丝速度和喷丝头拉伸比。To describe PAN-based Carbon Fiber Precursor coagulation process, a‘skin-core＇ structure model are established to simulate the wet-spinning process. The results show the low concentration of coagulant near the spinneret will help increase the spinning velocity and the stretching rate
