聚酰亚胺纤维纺纱工艺研究

Study on Polyimide Fiber Spinning Process

探讨聚酰亚胺纤维的纺纱工艺。简述了聚酰亚胺纤维的物理性能,介绍了聚酰亚胺纤维纺纱的工艺原则和具体的技术措施。通过强化纤维的梳理和转移;提高纤维的伸直平行度,使用防缠绕胶辊,设定合理的粗纱捻系数,细纱捻系数、隔距、加压等参数,在控制好温湿度的基础上,成功纺制出聚酰亚胺纤维14.8tex赛络纱。认为:根据聚酰亚胺纤维的性能,优化纺纱工艺可以保证成纱质量稳定。

Spinning process of polyimide fiber was discussed. The physical properties of polyimide fiber,pro- cessing principles and technology measures in the spinning process were introduced. The carding and transfer of the fiber were strengthened. Fiber parallel and straightness were optimized and improved. Anti-winding rubber- covered roll was used. Reasonable parameters such as roving twist factor, spinning yarn twist factor, gauge and pressure were set. Polyimide fiber 14. 8 tex siro yarn was spun successfully on the basis of better control temperature＆humidity. It is considered that according to the properties of polyimide fiber, spinning processing optimization can ensure stable quality of yarn.
