Abstract

The invention discloses a method for controlling twist redistribution. According to the invention, a back zone force application method is adiopted to apply external force on a strip located in a drawing back zone, a force application point is located on the strip surface of the drawing back zone, component force is produced by the applied external force in a vertical direction of the strip surface of the drawing back zone, a stable frictional force zone is provided for the position of the force application point, the strip is not easy to turn over, simultaneously, compactness of the strip can be effectively improved, twist redistribution can be effectively avoided, and resultant yarn levelness is improved.

Description

technical field

[0001] The invention belongs to the technical field of ring spinning, and relates to a method for controlling twist redistribution, in particular to a method for controlling twist redistribution when a large draft multiple is adopted in the rear draft zone of a ring spinning frame. Background technique

[0002] Ring spinning technology is the most widely used spinning technology at home and abroad. The drafting system is one of the most important parts of the spinning frame. It draws the fed coarse sand or sliver evenly into a A certain number of finished spun yarns, so the running stability and drafting uniformity of the system involved in the ring spinning frame will directly affect the yarn quality and output of the spun yarn. The improvement of the drafting mechanism of the traditional spinning frame is also one of the most popular research directions in the spinning field.

[0003] At present, general-purpose spinning frames all adopt a three-roller dou...
