Problems solved by technology

[0033] The present invention aims to solve the problem that the existing semi-continuous spinning machine, especially in the production of viscose filaments by a semi-continuous spinning machine, has insufficient filament response, resulting in the inability to increase the spinning speed, and the winding device of the semi-continuous spinning machine It is located under the spinning roll. Since there is water and acidic solution on the spinning roll, the winding device is easily polluted by water and acidic solution on the spinning roll. A new type of semi-continuous spinning machine is provided to produce viscose The filament yarn method and device achieve the purpose of increasing the spinning speed while ensuring sufficient response of the yarn, thereby ensuring quality, improving production efficiency, and reducing costs

Abstract

The invention relates to a spinning process of a semicontinuous high-speed spinning machine, which belongs to the field of the spinning technology of semicontinuous high-speed spinning machines. The process includes the steps of colloid feeding, filament formation, spinning and winding, a spinning mechanism in the spinning step comprises at least one spinning roller which is horizontally arranged relative to an operating surface of a spinning surface, and the shaping part of a winding mechanism in the winding step is located on the other side which is outside the area between wall plates of both sides of a housing and opposite to the spinning surface. The spinning process solves the problems in the prior art; by changing the arrangement direction of the spinning rollers, filaments can travel for a longer distance and more sufficiently react with acid bath while the spinning speed of the spinning machine is increased and the structures of the other parts of the original equipment are not changed, and thereby both the efficiency of production and the quality of products are taken into account; because the winding mechanism is arranged outside, under the acid environment, the corrosion to the filaments, the winding equipment and a control system thereof is little, and thereby the spinning machine can be conveniently maintained and operated by workers.

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...
