Spinning technology of semi continuous high speed spinning machine

Abstract

The invention relates to a spinning technology of a semi continuous high speed spinning machine, belongs to the technical field of semi continuous spinning machine spinning, and comprises the steps of glue supplying, filament forming, spinning and winding, wherein the spinning is accomplished by a spinning device which comprises one or more spinning rollers arranged on an operating surface corresponding to the spinning surface, the filament winds around the spinning roller, the drafting, solidification and deacidification of the spinning step are accomplished under the rotation of the spinning roller. According to the spinning technology provided by the invention, the problems that the spinning speed can not be accelerated and dual attention to the working efficiency and the product quality cannot be given, caused by the insufficiency reaction of the semi continuous high speed spinning machine filament, are solved, the changing of the spinning roller distribution direction enables the spinning machine to accelerate spinning speed and reserve the structure of other parts of the conventional device, the filament to walk farther, and the reaction of the filament and the acid bath to be more efficient, both the working efficiency and the product quality are considered.

Description

technical field [0001] The invention relates to a spinning process, more specifically, the invention relates to a spinning process of a semi-continuous high-speed spinning machine, which belongs to the technical field of semi-continuous spinning machine spinning. Background technique [0002] Pure methyl cellulose is extracted from cellulose raw material, called pulp. Treat with caustic soda and carbon disulfide to obtain orange-yellow cellulose xanthate sodium, and then dissolve it in dilute sodium hydroxide solution to become viscous spinning stock solution, called viscose. After the viscose is filtered, matured and defoamed, it is wet-spun, and the coagulation bath is composed of sulfuric acid, sodium sulfate and zinc sulfate. Sodium cellulose xanthate in the viscose reacts with sulfuric acid in the coagulation bath to decompose, and the cellulose is regenerated and precipitated. The obtained cellulose fiber becomes viscose fiber after washing, desulfurization, bleaching...

AI Technical Summary

Problems solved by technology

[0033] The present invention aims to solve the problem that the existing semi-continuous spinning machine, especially the production of viscose filaments by the semi-continuous spinning machine, has a short walking distance and insufficient reaction, which leads to the inability to increase the spinning speed, and provides a semi-continuous spinning machine. The spinning process of the continuous high-speed spinning machine can increase the spinning speed while ensuring the walking distance of the silk sliver, and at the same time can ensure the full reaction of the sliver, thereby achieving the purpose of ensuring quality, improving production efficiency and reducing costs.
