Production method for bright, clean and soft yarn

Abstract

The invention discloses a production method for bright, clean and soft yarn, which is applied to technological improvement on twist rolling parts which are arranged at a drafting part of a spinning frame and are finally sent out from the downstream of a roller in a pair manner, and can be directly applied to technological improvement on the spinning frame, an original yarn guide hook is replaced by a cyclone generator, a twist falling effect of the original yarn guide hook is reduced, rotational flow generated by compressed air is effectively utilized to change twist transfer and yarn forming during forming of the yarn, the flow quantity of the compressed air can be changed through an air pressure valve according to different yarn counts and process requirements and ranges from 0 to 0.6MPa, so that the reduction of yarn hairiness is facilitated, and the purposes of reducing the yarn hairiness, making the yarn softer and more fluffy and improving the yarn performance are achieved.

Description

technical field [0001] The present invention relates to the new technology field of ring spinning, in particular to a technical transformation of the winding and twisting part applied in the downstream of the drafting device of the ring spinning frame, which can reduce yarn hairiness, Yarn processing method with fluffy yarn body. Background technique [0002] Ring spinning technology is currently the most widely used spinning technology at home and abroad, but this technology increases the amount of hairiness due to the existence of twisting triangles. In recent years, many methods have been adopted to change the shape of the twisting triangle, such as compact spinning, cable spinning, dislocation spinning and other technologies, so as to reduce hairiness. [0003] The compact spinning technology mainly adds a fiber control area in front of the traditional drafting device, and uses the airflow to laterally condense the fiber bundles passing through the control area, so that...

AI Technical Summary

Problems solved by technology

However, the surface of the grooved roller is prone to fluff, and the mechanical grooved roller is easy to cause fiber damage, so it has a certain negative impact on the yarn quality

The technical starting point of dislocation spinning is to change the shape and size of the twisting triangle through the dislocation of the drafting unit and the twisting and winding unit, thereby changing the movement of fibers during the twisting process, and improving the yarn quality through the change of the yarn structure , but the improvement effect is limited
