Spinning process of bamboo-like flat filaments produced by semi-continuous high-speed spinning machine

Abstract

The invention relates to a spinning process of bamboo-like flat filaments produced by a semi-continuous high-speed spinning machine and belongs to the technical field of spinning of semi-continuous spinning machines. The spinning process comprises glue supply, filament strip forming, spinning and winding. The spinning process is characterized in that the glue supply is achieved through a glue supply device which comprises a metering pump, a glue supply tube and a filter; the metering pump is connected with a frequency converter which is used for controlling the amount of the glue supply of the metering pump; the frequency converter controls the metering pump to perform intermittent glue supply; the spinning is achieved through a spinning device which comprises at least one spinning roller which is horizontally arranged relative to an operating surface of a spinning surface; and filament strips surround the spinning roller to achieve drafting, solidification and deacidification in the spinning processes under the rotation of the spinning roller. The spinning process of the bamboo-like flat filaments produced by the semi-continuous high-speed spinning machine has the advantages of solving the problems that the filament strips of the semi-continuous spinning machines are inadequate in response, so that the spinning speed cannot be improved and the production efficiency and product quality cannot be integrated, enabling the arrangement direction of the spinning roller to be changed to enable the spinning speed of the spinning machine to be improved and enabling the high quality bamboo-like flat filaments to be spun out.

Description

technical field [0001] The invention relates to a spinning process, more specifically, the invention relates to a spinning process for producing slub-shaped flat yarns with 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 af...

Problems solved by technology

[0036] The present invention aims to solve the problem that the existing semi-continuous spinning machine, especially in the production of viscose filaments by the semi-continuous spinning machine, has a short walking distance and insufficient reaction, so that the spinning speed cannot be increased and high-quality spinning cannot be achieved. To solve the problem of slub-shaped flat yarn, provide a spinning process for producing slub-shaped flat yarn with a semi-continuous high-speed spinning machine, so as to increase the spinning speed and ensure the walking distance of the yarn, and at the same time ensure that the yarn The reaction of strips is sufficient, so as to achieve the purpose of ensuring quality, improving production efficiency and reducing costs, and can spin slub-shaped flat yarn with high quality
