中文摘要：

一个试验性的平台被构造在转子旋转联合起来以内拍摄纤维运动，它基于类似理论一个透明转子和一条运输隧道主要是镇静的。纤维将在运输隧道拉长并且聚在一起进纤维捆。纤维的速度沿着入口正在增加到运输隧道的插头，并且纤维最大值速度出现在运输隧道的插头。纤维捆的笔直与运输隧道的集中度有关，并且集中度越大，纤维捆拉长越多 straighter。结果将提供有用卓见给转子旋转的形成纱的机制。

英文摘要：

An experimental platform is constructed to photograph fibers＇ motion within rotor spinning unit, which is mainly composed of a transparent rotor and a transport channel based on the similarity theory. The fibers will stretch and gather into a fiber bundle in the transport channel. The velocity of fibers is increasing along the inlet to the outlet of the transport channel, and the fibers＇ maximum velocity appears at the outlet of transport channel. The straightness of the fiber bundle is related to the convergence degree of the transport channel, and the greater the convergence degree is, the straighter the fiber bundle stretches. The results will provide a useful insight to the yam-forming mechanism of rotor spinning.
