Heavy-denier-yarn spinning technology of semi-continuous and high-speed spinning machine

Abstract

The invention relates to a heavy-denier-yarn spinning technology of a semi-continuous and high-speed spinning machine, and belongs to the technical field of spinning of the semi-continuous and high-speed spinning machine. The technology comprises the steps of glue supplying, thread-line forming, spinning and winding. The spinning is finished through the spinning device, the spinning device comprises three spinning rollers which are transversely arranged relative to an operation face of a spinning surface, the three spinning rollers are respectively a drafting roller, a solidifying roller and a disacidifying roller, thread-lines sequentially surround the drafting roller, the solidifying roller and the disacidifying roller, and the drafting, the solidifying and the disacidifying in the spinning steps are finished under the rotation of the spinning rollers. The heavy-denier-yarn spinning technology of the semi-continuous and high-speed spinning machine solves the problems that due to the fact that response of thread-lines of a semi-continuous spinning machine in the prior art is insufficient, the spinning speed can not be accelerated, and the production efficiency and the product quality can not be improved at the same time; by changing the arrangement direction of the spinning rollers, the thread-lines can walk a longer distance while the spinning speed of the spinning machine is accelerated and structures of other parts of original equipment are not changed, the thread-lines and acid bath react more fully, and the production efficiency and the product efficiency can be improved at the same time.

Description

Technical field [0001] The present invention involves a spinning technology. More specifically, the invention involves a semi -continuous high -speed spinning machine, which is a semi -continuous spinning wire spinning technology field. Background technique [0002] Pure nailulose is extracted from cellulose raw materials, which are called pulp.Treatment with alkaline and disposol carbonide, orange -yellow cellulose sodium talcate is obtained, and then dissolved in a dilute sodium oxide solution, which becomes a viscous spindle raw liquid, called sticky glue.After filtering, cooked, and off -bubbles, the sticky glue is performed by wet spinning. The solidified bath is composed of sulfuric acid, sodium sulfate and zinc sulfate.The cellulose talcate in the sticky glue decomposes the sulfuric acid in the solidified bath, and the cellulose is regenerated and precipitated. The cellulose fiber is washed, desulfurized, bleached, and dry.The chornes of sticky filaments, that is, the type...

AI Technical Summary

Problems solved by technology

[0034] The present invention aims to solve the problem that the existing semi-continuous spinning machine, especially the semi-continuous spinning machine in the production of coarse denier yarn, has a short walking distance of the sliver and insufficient reaction, which leads to the inability to increase the spinning speed, and provides a semi-continuous spinning machine. The coarse denier spinning process of the high-speed spinning machine can increase the spinning speed while ensuring the walking distance of the sliver reaction, 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.
