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, etc., and at least four spinning rollers on the existing spinning machine can realize the basic function of spinning, which makes the structure of the whole machine complex and increases the energy consumption in the spinning process

Abstract

The invention relates to a spinning technology of a high-speed spinning machine provided with a single spindle passive winding device. The spinning technology comprises the steps of glue feeding, strand forming, spinning and winding. A spinning device in the spinning step comprises at least one set of spinning rollers, and each set of spinning rollers comprise an upper spinning roller and a lower spinning roller, wherein the upper spinning roller and the lower spinning roller are used for drafting. A forming part of the winding device is located on the outer side of the area between the two side wall plates of a rack and the other side opposite to a spinning surface, and the winding device is the single spindle passive winding device. Due to the fact that the winding device is arranged externally, corrosivity on strands, on the winding device and on a control system thereof is small under an acid environment, and maintenance and worker operation are convenient to carry out; due to the fact that an existing centrifugal cylinder needs to rotate at a high speed, energy consumption is high, the winding device only needs to meet the speed of the spinning rollers, no other energy consumption is needed, and therefore the total power is small.

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 equipped with a single-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, blea...
