Problems solved by technology

[0003] Traditional cotton fiber dyeing adopts high-temperature scouring treatment. Generally, soda ash or scouring agent is added to boil the cotton. The temperature is high and the energy consumption is high. After scouring, the corner water must be released, otherwise the dyeing rate will be reduced. Increase the amount of dye
At the same time, cold water washing should be carried out, and the temperature should be lowered to below 60 degrees, otherwise it will be easy to stain, so the water consumption is relatively high, so the energy consumption of various items is relatively high. In order to further reduce energy consumption, it is urgent to improve the process

Embodiment 1

[0024] A kind of cotton dyeing process comprises the following steps:

[0025] (1) Pretreatment: Add the compound of sodium alkylsulfonate and alkyl polyethylene glycol ether in water at 55-70 degrees Celsius, then add cotton to water and boil for 20-30 minutes, take it out and wash it with water for 10 minutes;

[0026] (2) Dyeing treatment: add the cotton treated in step (1) into the dyeing vat at room temperature, then add dye, soak for 10 minutes, then add sodium sulfate three times, each time at an interval of 3-10 minutes; then add caustic soda into the dyeing vat After adding caustic soda, the water temperature is raised to 60°C, and the heating rate is 1°C per minute;

[0027] (3) Post-processing: add the dyed cotton in step (2) into boiling water and boil for 10 minutes, then add soaping agent and boil for 10 minutes, and then wash with water 2-3 times; the above soaping agent is non-foaming soaping agent , is a modified maleic acid-acrylic acid polymer.

Abstract

The present invention relates to the technical field of dyeing processes in textile industry, more particularly to a cotton dyeing process, which comprises: (1) placing cotton into a dyeing jar, adding normal temperature water into the dyeing jar while adding a whitening agent, and soaking for 10-20 min; (2) sequentially adding caustic soda, a hydrogen peroxide stabilizer and a penetrant to the dyeing jar; (3) adding hydrogen peroxide, increasing the water temperature to 95-98 DEG C at a speed of 1 DEG C / 1 min, and carrying out thermal insulation for 30 min; and (4) taking out the cotton, neutralizing with an acid liquid, and washing with deionized water until the ph value is 6-8. According to the present invention, the bleaching process and the whitening process are integrated into the one-step operation, such that the water consumption is saved, the electricity for heating is saved, the working time is saved, the working efficiency is improved, the bleaching effect and the whitening effect are substantially improved, and the treatment at the late stage is conveniently performed.

Description

technical field [0001] The invention relates to the technical field of dyeing process in the textile industry, in particular to a cotton dyeing process. Background technique [0002] With the progress of society and the improvement of living standards, people pay more and more attention to the environment, and the country's environmental protection policies are becoming more and more strict. Vigorous rectification is being carried out. Energy conservation and emission reduction have become the most important goals at present. At the same time, the protection of water resources Insufficient, requires people to reduce the amount of printing and dyeing, reduce unit dyeing loss. [0003] Traditional cotton fiber dyeing adopts high-temperature scouring treatment. Generally, soda ash or scouring agent is added to boil the cotton. The temperature is high and the energy consumption is high. After scouring, the corner water must be released, otherwise the dyeing rate will be reduced....
