摘　　要：介绍黄麻化学物理联合精细化工艺过程,为提高黄麻纤维的可纺性,研究不同物理细化路线、工艺参数及细化步骤对黄麻纤维力学性能的影响规律,通过对比分析黄麻纤维的线密度、长度和力学性能指标得出:梳理工艺对黄麻纤维线密度、长度和强力都有非常大的影响,是黄麻物理精细化过程中控制的关键因素;经过预处理—长麻牵切—梳理工艺得到的黄麻纤维线密度为16.65 dtex,长度为30.16 mm,可用于棉纺工艺流程。Physicochemieal refining process for jute fibers was presented. With the aim to improve the spinnability of the jute fiber, the effects on mechanical properties of jute fibers in varying processes, parameters, and refining steps were analyzed and discussed. By analyzing the average length, linear density, and breaking strength of jute fibers obtained by different processes, the results show that hackling process has great effect on the average length, linear density, and breaking strength of jute fibers and is a key controlling factor in the physical refining; jute fibers with the fineness of 16.65 rex and length of 30.16 mm that are obtained through pretreatment-long fiber drawing/cutting-hackling are suitable for cotton spinning system.
