摘　　要：针对苎麻常规纺纱过程中,超长纤维比例高、纤维长度不匀大而导致成纱条干差、毛羽多的问题,本文对苎麻常规纺纱工艺中的初精梳条进行牵切,以降低其超长纤维比例,改善纤维长度整齐度,并在细纱工序采用非滑溜牵伸,从而使苎麻成纱质量得到显著提高,并大大缩短了纺纱工艺流程。Because of the high ratio of long fiber and the poor uniformity of fiber length,the quality of ramie yarn is not good,especially with poor yarn evenness and much hairiness.In this paper,the re -combed silvers of ramie were stretch -broken to reduce the long fiber proportion and improve the fiber u-niformity,and then non -slip drafting was used in spinning.The results showed that both the quality and the spinning efficiency of the ramie yarn were highly improved.
