旋流器纱道截面形状对环锭纺纱线质量的影响

 为了进一步优化旋流器的内部结构，更好的提高成纱的质量，本文设计并使用了两种不同截面形状纱道的旋流器来减少环锭细纱毛羽，测试了样品的毛羽、断裂强力以及条干不匀率等主要指标，分析了纱道截面形状对成纱质量的影响，并与普通环锭纺细纱质量进行了比较。结果表明：两种截面形状的旋流器均对环锭细纱的性能有较大影响。由于两种截面形状纱道内气流状态不同，二者对纱线性能的影响程度不同。相同纺纱工艺参数条件下，圆形纱道旋流器所纺纱线>3mm毛羽指标、断裂强力和条干不匀率等指标均优于椭圆形纱道旋流器。因此，旋流器的纱道截面形状选择圆形较合理。

Effect of yarn trajectory cross-sectional shape of cyclone on yarn properties

In order to further optimize the inside structure of cyclone setting and improve the quality of yarn,two cyclones with different yarn trajectory cross-sectional shape were designed to reduce hairiness of ring spun yarns.The performance indexes of the sample yarns such as hairiness,breaking strength,and unevenness were tested and compared with those of traditional ring spun yarns.The effects of yarn trajectory cross-sectional shape on yarn properties were analyzed.The results showed that both of the two cycl...
