A method for improving the quality of viscose fiber products

Abstract

The invention relates to the field of viscose production, in particular to a method for improving quality of viscose products. The method is characterized in that a spinning threading method based on improvement of quality of viscose staple products comprises the steps as follows: a, mounting a spray head during threading, and pressing down a carrier gear; b, pressing a gooseneck into an acid bath tank by 1 / 3 when viscose is exposed from the surface of the spray head, and pressing the whole gooseneck into the acid bathing tank after 10 seconds; c, fishing silk with two hands after the silk emerges from the surface of the acid bath, lifting the silk, arranging the silk in a silk guide hook in a sleeving mode, pulling the silk for about 3-4m, and pulling apart the silk; d, enabling the silk obtained in the step c to pass through an acid scraper, and winding the silk around a silk guide rod and a spinning disc to enter a claw; e, pulling out the silk; f, cutting off the silk; g, rapidly clustering the silk by another worker during conducting of the step f.

Description

technical field [0001] The invention relates to the field of viscose fiber production, in particular to a method for improving the quality of viscose fiber products. Background technique [0002] "With the advancement of science and technology and the development of the market economy, people gradually bid farewell to the shortage economy. Under the conditions of the buyer's market, the competition among enterprises is extremely fierce, and the essence of competition is quality competition. As a result, enterprises with good quality will be eliminated Enterprises with poor quality. Viscose staple fiber has a large number of rubber blocks or parallel yarns during the spinning head-up operation. etc., which is not conducive to the company's promotion of product quality and company reputation. For this reason, a method for improving the quality of viscose fiber products came into being. [0003] In the existing staple fiber production process, the spinning post periodically re...

AI Technical Summary

Problems solved by technology

[0003] In the existing staple fiber production process, the spinning post periodically replaces the nozzles to ensure continuous and stable production, but in this process, more rubber blocks and parallel filaments are often generated due to the influence of the head-up operation, which affects Finished product quality

In response to this impact, some manufacturers will isolate and degrade the products during the replacement of the nozzles. This method is not conducive to product quality and affects the company's profits; Cutting off, although this method has improved compared to the former, it cannot completely eliminate the influence of glue blocks and parallel wires, for the following reasons:

[0004] 1. The total length from the head spindle position to the tail spindle position of the spinning machine is about 30m. When the head spindle position (and the middle spindle position) is raised to produce rubber blocks, the rubber blocks will run along the main tow to the machine tail , so that the rubber block will adhere to other fibers due to being squeezed and damaged by the main tow. Blocks cannot be cut off, thus affecting product quality

[0005] 2. When the spinning head is raised, the lifting yarn will be inserted into the main yarn and run towards the tail of the machine (if it is not embedded in the main yarn speed, the lifting yarn will be stuck on the horn of the guide wire, causing blockage)

However, since the main tow is relatively thick, its running speed is relatively fast (53m / min), and the distance between adjacent equipment is only 150cm (from the tail of the spinning machine to the first pull), so it is impossible for the operator to completely pull out and cut them off one by one. And there are safety risks, often uncut wires enter the production system, affecting product quality
