Abstract:

Compared with conventional ring spinning, compact spinning with a suction groove can reduce hairiness and improve yarn quality, and it has certain advantages to long staple fibre. In this article, we analyse the changing rule of rotational speed and study the change curve of the frictional coefficient in the gathering zone. The results show that the fibre bundles’ rotational speed at each point along the surrounding arc gradually decreases from the maximum to zero in the gathering area, but the rotating speed of the fibre bundles is constant in the suction hole. The angle between the parallel component speed and that at each point is near to a linear change in the no suction hole, with there being no change in the suction hole. The parallel component of the frictional coefficient for each point is a variable in the no suction hole, being constant in the suction hole.
