摘要
为了制备出高质量的纤维,对纺丝机械辊筒结构进行优化十分必要。以聚对苯二甲酸乙二醇酯(PET)纺丝为例,通过计算机辅助技术对纺丝机械辊筒进行了结构优化。仿真结果表明,当辊筒壁厚为3.0 mm、辊子轴头直径突变部位粗糙度为3.2 Ra、辊筒的轴头和辊子配合粗糙度为3.2 Ra、辊筒形状为细长型圆筒状、长径比为3.0时,所纺出的PET纤维的直径较为均一,直径为5μm,且纤维不存在缺陷。另外,实际纺丝试验结果表明,仿真结果的准确度较高,10组平行试验中最小误差为0,最大误差为0.8%,标准差仅为0.02μm。仿真结果具有高度准确性,且优化后的辊筒结构更适于纺出高质量的PET纤维。通过计算机辅助技术对纺丝机械辊筒结构进行优化,具有高效、精准的特性,能够广泛应用到其他纤维纺丝的器械结构优化。
To prepare high quality fiber, it is necessary to optimize the structure of spinning machinery roller.Taking polyethylene terephtalate(PET) spinning as an example, the structure of spinning machine roller is optimized by computer aided technology.The simulation results show that when the wall thickness of the roller is 3.0 mm, the roughness of the tip of the roller is 3.2 Ra, the roughness of the tip of the roller and the roller is 3.2 Ra, the shape of the roller is slender cylindrical, and the aspect ratio is 3.0,the diameter of the spunned PET fiber is relatively uniform, 5 μm, and the fiber has no defects.In addition, the actual spinning experiment results show that the accuracy of the simulation results is high, the minimum error is 0,the maximum error is 0.8%,and the standard deviation is only 0.02 μm.The simulation results are highly accurate, and the optimized roller structure is more suitable for spinning high-quality PET fiber.The roller structure optimization of spinning machinery by computer aided technology has the characteristics of high efficiency and precision, which can be widely used in the structure optimization of other spinning apparatus.
