Spinning process of three-spinning-roller semicontinuous high-speed spinning machine

Abstract

The invention relates to a spinning process of a three-spinning-roller semicontinuous high-speed spinning machine, and belongs to the technical field of spinning of semicontinuous spinning machines. The spinning process comprises the steps of glue supplying, silk strip forming, spinning and winding. The spinning is completed through a spinning device, the spinning device comprises three spinning rollers transversely arranged relative to an operating surface of a spinning face, silk strips surround the spinning rollers, and drafting, solidification and deacidification in spinning steps are completed under rotation of the spinning rollers. The spinning process solves the problem that due to the fact that the silk strips of a semicontinuous spinning machine in the prior art reacts insufficiently, the spinning speed cannot be improved, and consideration cannot be given to production efficiency and product quality at the same time; the distribution direction of the spinning rollers is changed, so the spinning speed of the spinning machine is improved, structures of other parts of original equipment are not changed, meanwhile the silk strips can be moved for longer distances and react with acid bath more sufficiently, and the consideration is given to the production efficiency and the product quality at the same time.

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 with three spinning rollers, belonging 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, de...
