In order to explore the principle about fibers,alignment and transfer in the"twisting thin place"on the ring frame,a cubic model was made to analyze the form of the model,the trend of the fibers,movement and the rule of the fibers′arrangement.

The Compact Spinning can eliminate the twist triangle of the conventional Ring Spinning.

The Compact Spinning can eliminate the twist triangle of the conventional Ring Spinning, so as to decrease the hairiness of yarns, increase tensile strength and elastic perfor-mance, decrease the breakage during the spinning.

In view of spinning-triangle, the disadvantage existing in traditional ring spinning, the types and characteristics of compact spinning systems which are used to eliminate spinning-triangle and therefore reduce yarn hairiness are introduced.
