Spinning process of spinning machine with novel single-spindle passive winding device

Abstract

The invention relates to a spinning process of a spinning machine with a novel single-spindle passive winding device, and the process comprises the steps of adhesive feeding, filament forming, spinning and winding. The forming parts of the winding device are arranged on the outer side of an area between wall panels on both sides of a frame and on the other side which is opposite to a spinning surface; the winding device is the novel single-spindle passive winding device; due to the external winding device, the corrosion to filaments, the winding equipment and a control system thereof is low in an acid environment, so that the repair and the operation of a worker are convenient; due to the fact an existing centrifugal cylinder rotates at high speed, the energy consumption is high, while the winding device only needs to reach the speed of spinning rolls, no other energy is consumed, so the power of the whole machine is low.

Description

technical field [0001] The invention relates to a spinning process, more specifically, the invention relates to a spinning process of a spinning machine equipped with a novel 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, bleaching...

[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 o...
