balloon control ring

Finally it also deals with the theoretical analysis of balloon control ring, with its advantageous effect in reducing the value of T0 / ω.

本文是在前文～(1)基础上对环锭纺极限气圈与气圈稳定性理论作进一步的研究,给出了气圈方程的椭圆积分解,用一系列曲线图来表示纱线张力与气圈形态之间的相互关系,并与正弦近似解进行了对比,结果表示在常用情况下两种解相当接近;最后又对气圈控制环进行了理论分析,也以一系列曲线图形式给出其合理的安装高度及其对降低T_0/ω～2)值所能带来的明显效果。

Effect of Spinning Movable Balloon Control Ring on Finish Yarn Hairiness

细纱可移动气圈控制环对成纱毛羽的影响

As to the increasing hairiness due to inter-friction of yarn in process of high speed rewinding of cop,it is pointed out that addition of air balloon controller or addition of backset hairiness reduction device PERLA-A can markedly reduce hairiness and increase yarn strength and such.

基于络筒工序细纱管纱高速退绕因自身摩擦、纱线张力的影响使纱线毛羽增加的现状,提出在自动络筒机上加装气圈控制器或加装PERLA-A型涡流毛羽减少装置,不仅将使毛羽明显减少,还可提高纱线强力,并具有其它积极效果。
