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
[0033] To sum up, in the existing spinning process, the winding device of the semi-continuous spinning machine is located below the spinning roll, and the winding device is easily damaged by spinning due to the dripping of water and acidic solution on the spinning roll. The problem of water dripping on the spinning roll and the pollution of acidic solution; and in the existing process of spinning with continuous spinning machine, in order to finally obtain the dry filament in the tube, the spinning roll integrates drafting, washing The structure of deacidification, drying and oiling makes the structure of the whole machine complex and increases the energy consumption in the spinning process

Abstract

The invention relates to a spinning process of a spinning machine provided with three passive winding devices. Including glue supply, thread forming, spinning and winding, the forming part of the winding device is located outside the area between the wallboards on both sides of the frame, on the other side opposite to the spinning surface, and the winding The winding device is a three-spindle passive winding device. Since the winding device of the present invention is externally installed, it is less corrosive to the thread, winding equipment and its control system in an acidic environment, and is convenient for maintenance and worker operation. The existing centrifugal cylinder needs to rotate at high speed, so the energy consumption is high, but the winding device of the present invention only needs to meet the speed of the spinning roller, without other energy consumption, so the power of the whole machine is small.

Description

technical field [0001] The invention relates to a spinning process, more specifically, the invention relates to a spinning process of a spinning machine provided with a three-spindle passive winding device, 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 dr...
