Polypropylene fiber spinning device and spinning method

Abstract

The invention discloses a polypropylene fiber spinning device and a spinning method. The polypropylene fiber spinning device comprises a spinning device body, a processing box is fixedly installed at the output end of the spinning device body, an inlet is formed in the inner wall of the left side of the processing box, an outlet is formed in the inner wall of the right side of the processing box, an air cooling assembly is arranged on the processing box, a hollow guide roller is arranged in the processing box, the two ends of the hollow guide roller are both of a closed structure, hollow rotating shafts are fixedly installed at the two ends of the hollow guide roller, and the two hollow rotating shafts both communicate with the interior of the hollow guide roller. The polypropylene fiber spinning device is reasonable in design and good in practicability, the integrated operation of cooling solidification and spinning oiling on the produced polypropylene fiber silk yarn can be achieved, the spinning efficiency is improved, the produced polypropylene fiber silk yarn can be rapidly and effectively cooled and solidified, and the polypropylene fiber yarns can be quickly and uniformly oiled, so that the spinning quality is improved.

Description

technical field [0001] The invention relates to the technical field of spinning equipment, in particular to a polypropylene fiber spinning device and a spinning method. Background technique [0002] Spinning, also known as chemical fiber forming, is a process of manufacturing chemical fibers. Some polymer compounds are made into colloidal solutions or melted into melts, and then pressed out from the spinneret pores to form chemical fibers. Polypropylene fiber is also called Polypropylene fiber is the product of synthetic fiber isotactic polypropylene fiber made from petroleum refining by-product propylene. Polypropylene requires a series of processing processes from manufacture to production, and spinning occupies an important role in its production process. It is an extremely important position, and the spinning device is usually used to spin the polypropylene fiber, cool and solidify, and oil the silk. [0003] However, in the prior art, in the production process of polyp...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a polypropylene fiber spinning device and spinning method, which solves the problem that the existing spinning device cannot realize the cooling and solidification of the produced polypropylene fiber yarn, and the integration of spinning and oiling The spinning efficiency is reduced, the cooling and solidification effect of the produced polypropylene fiber yarn is not good, the cooling and solidification of the yarn is uneven, which affects the spinning quality, and the oiling of the polypropylene fiber yarn is uneven, which will also affect The problem of spinning quality
