旋流器对环锭纺不同线密度纱线性能的影响

采用安装在传统环锭细纱机的旋流器加工不同线密度的纱线，探讨了旋流喷嘴内部高速旋转气流对纱线加捻成形的影响。结果表明：旋流器的使用能够有效地减少纱线毛羽，但在优化纱线强力、条干不匀率等方面作用不是很明显且对不同线密度纱线质量的改善程度存在一定的差异。采用纱道为2 mm，气道为1.4 mm的旋流器，所加工不同线密度纱线的质量都有一定程度的提高，其中线密度10 tex 纱线的3 mm以上毛羽、断裂强度和条干不匀率质量指标的改善均优于其他四种纱线，为研究最好地降低纱线的成纱毛羽提高纱线质量而选择合适尺寸的旋流器提供参考。

Effects of cyclone on properties of ring spun yarns with different linear densities

The cyclone would be installed on conventional ring spinning frame for processing different fineness yarns. In the process of yarn-spinning, the rotating airflow inside the cyclone can make an effect on the twisting formation of yarn, thus significantly reducing yarn hairiness longer than 3mm. The results indicated that although cyclone can effectively reduce yarn hairiness, not better improve yarn breaking strength and unevenness. The quality of different fineness yarns processed by the cyclone of yarn trajectory for 2 mm, air trajectory for 1.4 mm has improved. The improvement degree of 10 tex yarn properties including hairiness (>3mm), breaking strength and unevenness were better than the others’. This paper provides a reference for research on choosing the right size of cyclone to reduce hairiness and improve yarn quality.
