【摘要】 本文假定凝固浴流体为斯脱克斯(Stocks)流体,利用奈维—斯脱克斯公式,推导了适用于干湿法紧张下流式的浴液对丝条摩擦阻力公式。并从理论上讨论了影响芳纶干湿法纺丝速度及纤维质量的流体因素,进而改进了纺丝装置,使芳纶的纺丝速度及纤维质量有了明显提高。更多还原

【Abstract】 In this paper, we suppose that coagulation fluid be Stocks one. Based upon the Newei-Stocks equation, we get the equation of the skin friction drag of the fibre in the coagulation bath in dry-wet spinning method （F_f=4πl₁μ（v₂-α_xv_b）/mn. V_b=（R₁²/8μ）（dρ/dz）-ρg）. We discussed the fluid factors that affected the spinning velocity and properties of fibre in the dry-wet spinning method. Furtherly, we improved the coagulation equipment and raised the spinning velocity and the fibre properties更多还原
