Abstract

The invention provides a device for improving the performance of compact spinning yarn. A cover is provided on the special-shaped tube corresponding to the spinning position, and a suction chute is provided on the cover. The suction chute adopts a three-stage separated non- The continuous cut includes the first cut, the second cut and the third cut arranged sequentially from top to bottom; the two sides of the cover are provided with rotatable airflow guide pieces. The invention also provides a method for improving the performance of the compact spun yarn, which uses the principle of aerodynamics to change the suction chute into a three-stage type, and installs an airflow guide plate in the yarn accumulation area. This method can increase the airflow velocity in the gathering area, and ensure that the fiber bundles will be subjected to a greater gathering effect when they enter the gathering area. The width of the fiber bundles will shrink rapidly, and the fibers will be closely entangled, thereby increasing the strength utilization of the fibers and improving the yarn formation. It can also reduce the possibility of fiber exposure on the surface of the yarn, thereby reducing the number of yarn hairiness, and has a significant effect on improving the overall performance of the yarn.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a device and method for improving the performance of compact spinning yarns. Background technique [0002] Compact spinning is a new spinning technology developed on the basis of ring spinning. It is mainly to install a concentrating device before the yarn is twisted, and use the action of machinery or airflow to reduce or even eliminate the twisting triangle. Among them, the negative pressure compact spinning device is the most widely used concentrated spinning method at home and abroad. The concentrated action of the airflow makes the fiber bundle no longer a flat ribbon during the twisting process, but a cylindrical beard, thus To achieve the purpose of reducing hairiness, improving yarn quality, optimizing yarn structure, and facilitating subsequent processing. [0003] At present, compared with the traditional ring spinning yarn, the quality of the compact spinning yarn h...
