摘要：以长度为38 mm聚酰亚胺纤维为样本，在分析聚酰亚胺纤维性能的基础上，研究其纯纺纱及与粘胶纤维混纺纱的加工工艺。通过采用小机型、低转速的加工方式对比试验证明其纺纱开发的可行性；采用与粘胶纤维条混方式成功纺制聚酰亚胺纤维含量为21%～79%的4种18.2 tex混纺纱，并对纱线性能进行了测试。指出：聚酰亚胺纤维具有优良的力学性能和低表面摩擦、低回潮性能和高比电阻的特点，随着其含量的增大，成纱条干不匀率和纱线毛羽呈增加趋势、纱线外观逐渐恶化、纱线断裂强度呈增长趋势，并在聚酰亚胺含量占42%～79%时增长趋势明显；混并至少配置三道，并需保护好半制品熟条表面的油剂及工作辊的抗静电处理。

Abstract:Sampling polyimide fiber with the length of 38 mm,analysis is done to the spinning process of pure yarn of polyimide fiber or the blended yarn with the viscose fiber.The application of the small models,processing methods of low speed tests prove the feasibility of the blending spinning development with viscose fiber with 4 kinds of 18.2 tex yarn with polyimide fiber content of 21%～79%.Conclusion is made that polyimide fiber has excellent mechanical properties and low moisture performance and high resistance,and low surface friction characteristics.As the content increases,yarn evenness and hairiness increase with yarn appearance gradually deteriorated and breaking strength growing.When the content of polyimide accounts for 42%～79%,the content growth is obvious.Something must be done to the three mixed configuration,antistatic agent and oil processing of semi-finished products and the work roll.
Key Words:polyimide fiber;viscose fiber;blended yarn; evenness; hairiness; breaking strength
