Embodiment 1

[0024] The cloth weight of this process is 766Kg, and the total water consumption is 6900L:

[0025] 1g / L chelating dispersant 6.9 Kg,

[0026] 0.415% Reactive Yellow 3178.9g,

[0027] 0.105% Reactive Red 804.3g,

[0028] 0.94% Reactive Blue 7200.4g,

[0029] 30g / L Yuan Mingfen 207 Kg,

[0030] 9g / L soda ash 62 Kg,

[0031] 60℃X40min

[0032] At room temperature, add 6.9 Kg of chelating dispersant first, then add dye for 30 minutes, run for 10 minutes until the dye is fully dissolved into the dye solution,

[0033] Start adding Yuanmingfen Na 2 SO 4 207Kg is divided into 3 times, the first time adding 1 / 3 a total of 69Kg quantitative 10 minutes, the second adding 1 / 3 a total of 69Kg quantitative 10 minutes, the third adding 1 / 3 a total of 69Kg quantitative 10 minutes, running for 10 minutes MingfenNa 2 SO 4 Dissolved into the dye liquor, the active molecules of the dye are evenly absorbed by the fabric fiber molecules,

[0034] Add soda ash Na 2 CO 3 62Kg is slow...

Abstract

The invention relates to a dyeing and low-temperature post-treatment process for a cotton knitted fabric. The dyeing and low-temperature post-treatment process comprises the steps of adsorption of an active dye, accelerating of the active dye, fixation dyeing of the active dye and low-temperature post-treatment cleaning. The method is good in fastness, complete in chromatography, less in used medium, capable of being prepared into different colors to meet requirements, less in environmental pollution and capable of reducing steam energy consumption and electricity consumption energy consumption.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing, and particularly relates to a reactive dye dyeing and low-temperature post-treatment process for cotton knitted fabrics. Background technique [0002] The traditional dyeing and post-treatment processes are cumbersome and inefficient, and many chemical auxiliaries are used, which pollutes the environment, and the dyed colors are not bright enough. With the improvement of people's living standards, people's wearing requirements are becoming more and more strict. Not only are the fabrics required to be comfortable, but also color diversity and good fastness are required. In order to meet the needs of consumers, it is necessary to develop a reactive dyeing and low-temperature post-treatment process for cotton knitted fabrics. . SUMMARY OF THE INVENTION [0003] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies in the prior art, provide a kind of ...
