【摘要】 在环锭纺细纱机上安装旋流器,利用旋流器内部的旋转气流对纱线的加捻成形过程产生影响,以达到提高纱线质量的目的。介绍旋流器的结构以及在环锭纺细纱机上的安装位置,实验并分析旋流器中的空气压力以及旋流器的结构对纱线毛羽的影响。对安装旋流器前后纺制的纱线的毛羽、断裂强力以及条干不匀率进行对比实验。结果表明,安装旋流器后,纱线表面的毛羽降低,纱线的断裂强力提高,纱线的条干均匀度也有所改善。更多还原

【Abstract】 A swirler can be fixed on the ring frame.In the process of yarnspinning,the rotating airflow inside the swirler can exert an effect on the twisting formation of yarn,thus improving the quality of yarn.The structure of the swirler and its mounting position on the ring frame are introduced.Meanwhile,the experiment is conducted and the air pressure inside the swirler and the influence of the swirler′s structure upon yarn hairiness are analyzed.Moreover,a comparative experiment is carried out on hairiness,breaking strength and unevenness of yarns before and after the swirler is fixed on the ring frame.The results show that the hairiness on the yarn surface is reduced,breaking strength and evenness improved after fixing the swirler.更多还原
