High-fidelity spinning method and equipment for special-shaped cross-section based on cavitation effect

Abstract

The invention provides a specially-shaped section high-fidelity spinning method and device based on the cavitation effect. According to the specially-shaped section high-fidelity spinning method based on the cavitation effect, the cavitation effect is generated through a cavitation device according to different attributes of spinning materials, then spinning slurry is separated from spinneret orifices through microbubbles generated through the cavitation effect, it is ensured that the shape of the section of each fiber is consistent with the hole shape of a spinning nozzle, the fibers cannot block the spinneret orifices when the fibers are extruded out of the spinneret orifices, are immediately formed and solidify, and thus the effect that the shape of the fibers is kept, and the effect that the service life of the spinning nozzle or a spinning card is prolonged are achieved. According to the specially-shaped section high-fidelity spinning method based on the cavitation effect, due to the fact that the inner wall of the spinning nozzle is modified through nano-structures and nano-materials, frictional resistance between the spinning slurry and the spinning nozzle is greatly reduced, and formation of super thin denier specially-shaped fibers is promoted. The specially-shaped section high-fidelity spinning method and device based on the cavitation effect are used for achieving the purpose of improving high fidelity of super fine denier specially-shaped fiber graphs, and the service life of the spinning nozzle or the spinning card is greatly prolonged so that the operating cost can be reduced, and the production benefit can be improved.

Description

technical field [0001] The invention relates to the man-made fiber industry, in particular to a method and equipment for high-fidelity spinning with special-shaped cross-section based on cavitation effect. Background technique [0002] The cross-section of traditional chemical fibers is circular, and most of these fibers have the disadvantages of smooth surface, poor adhesion, easy pilling, no water absorption, and small coverage. Shaped fiber cross-section is one of the important methods to improve the performance of synthetic fibers. It mainly uses physical methods to make the original circular synthetic fibers into fibers with special cross-sectional shapes. Compared with the traditional round fiber, the special-shaped fiber has many excellent characteristics: first, it has good optical effect, especially the triangular fiber, such as silk, has a light splitting effect like a small prism, which can make the natural light split and then recombine, giving people a new look....
