Description

Clamping type false twist device

technical field

The utility model relates to the technical field of spinning, in particular to a clamping type false twisting device.

Background technique

Twisting is an important part of short fiber spinning. At present, ring spinning is still the most widely used spinning technology at home and abroad. Ring spinning consists of a steel traveler, a steel ring and a high-speed rotating spindle. The air circle and winding form will produce spinning tension and tension fluctuations. Excessive spinning tension and tension fluctuations will cause an increase in the yarn breakage rate, which limits the increase in spindle speed and output. In recent years, through the unremitting efforts of textile workers, a method and device for false twist assisted spinning to reduce yarn breakage in spinning have been proposed. There are six forms in summary. The first is air-flow rotating false twist, and the second is mechanical spinning. Center rotating false twisting, the third is belt twisting false twisting, the fourth is wheel twisting false twisting, the fifth is wheel surface friction false twisting, the sixth is dragon belt tangential friction false twisting. However, from the perspective of practical feasibility, only the second type of mechanical center rotating false twisting is more convenient to implement, and it is also widely used, while the other five false twisting forms are not good because of poor actual effect, or the mechanism is too complicated or even the application process. There are other additional problems in the process, basically no practical application.

Although the mechanical center rotating false twist is relatively convenient to implement, there are still some shortcomings in the actual use process. For example, Chinese patent CN1453401A, published on November 5, 2003, discloses a "processing method and equipment for single-ply torque-free ring-spun yarn". The control of structure and twist distribution realizes the processing of torque-free ring spun yarn on traditional ring spinning machines, but due to the great friction in the false twist section, the yarn quality is deteriorated, and the yarn breakage rate is still high. Suitable for high count yarns.
