在棉纺常规环锭细纱机和紧密纺环锭细纱机上进行了改变纱路的纺纱试验，测试对比了纱线性能指标。

Spinning tests on normal ring spinning frame and compact spinning frame with yarn path modified were carried out, and the performances of thus spun yarns were tested and compared.

细纱工序是成纱的一道关键工序，细纱机性能的优劣对成纱的产量和质量都有重要的影响。 目前，国内棉纺厂所使用的细纱机大多采用总轴传动方式，落纱过程通过人工操作完成。

The spinning working procedure is the most important one of the resultant yarn spinning, the capability of the spinning frame affects a lot to the crop and the quality of the resultant yarn.
