Spinning process of a high-speed spinning machine

Abstract

The invention relates to a spinning process of a high-speed spinning machine. Including glue supply, filament forming, spinning and winding, the forming part of the winding device in winding is located outside the area between the wall panels on both sides of the frame, on the other side opposite to the spinning surface, and the glue supply device The winding device is respectively located on the outside of the wallboard, and the winding device includes a wet cake winding device, and / or a wet drum winding device, and / or a wet skein winding device; the spinning device includes at least A set of spinning rolls, each set of spinning rolls includes the upper spinning roll and the lower spinning roll responsible for drafting. Due to the external winding device, the filaments, winding equipment and their control are in acidic environment. The system is less corrosive, and the glue supply device and winding device are located on the outside of the wallboard, so the number of glue supply devices and winding devices can be expanded according to different production needs, which greatly improves the production capacity of the spinning machine.

Description

technical field [0001] The invention relates to a spinning process, more specifically, the invention relates to a spinning process of a high-speed spinning machine, which belongs to the technical field of 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 and drying. Viscose filament is a kind of visco...

Problems solved by technology

[0009] Disadvantages: low spinning speed, high post-processing costs, and increased production costs

[0012] Disadvantages: Since the silk sliver is washed and dried immediately, the strength of the sliver is low, the whiteness is low, the sliver is rough, and the quality is not as good as that of the semi-continuous spinning machine; in order to increase the sizing of the silk sliver, the sizing needs to be removed when the embroidery thread is dyed. Increase the production cost of downstream products; high quality requirements for raw materials (viscose)

[0021] 1. The above structure limits the length of the roller. The time for the viscose filament to walk on the roller is short, and the forming time of the viscose filament is short. If the spinning speed is to be increased, the reaction time of the viscose filament will inevitably be insufficient and the product quality will be reduced. , so the efficiency of the traditional semi-continuous spinning machine is reduced;

[0022] 2. In order to improve efficiency, multiple filaments are usually processed at the same time, but when multiple viscose filaments are wound on the existing spinning roller, they are easy to twist, causing the viscose filaments to break and affecting the viscose filaments. product quality;

[0024] 4. All the spinning rollers are fixed at one end, which will inevitably require an extremely complex transmission mechanism to drive the rotation of the spinning rollers, which will also lead to an increase in the failure rate, and when changing the type of silk yarn and changing the rotation speed, it is necessary to stop the machine. Then replace the gears in the transmission system, which reduces the production efficiency and increases the production cost

The above-mentioned utility model is a continuous spinning machine, which is equipped with a drying device, and the dried filaments are directly formed into a tube, and the tube forming device is located outside the drying device, but since the spinning roller integrates de-drawing, washing The structure of deacidification, drying and oiling makes the structure of the whole machine complex and increases energy consumption

[0032] To sum up, in the existing spinning process, the winding device of the semi-continuous spinning machine is located below the spinning roll. Since the spinning roll has water and acidic solution dripping, the winding device is easily damaged by spinning. Contamination of water and acidic solution dripping from the spinning roll; and in the existing spinning process using a continuous spinning machine, in order to finally obtain a tube of dry filament, the spinning roll integrates drafting, washing Deacidification, drying and oiling, etc., and the existing spinning machine has at least four spinning rollers to realize the basic function of spinning, which makes the structure of the whole machine complex and increases the energy consumption in the spinning process
