Problems solved by technology

But everything has two sides. The affinity of reactive dyes to cotton fibers is not high, and the dye uptake rate is lower than that of direct dyes and vat dyes. Increased the cost, but also increased the difficulty of washing after dyeing and the amount of sewage treatment

Embodiment 1

[0044] (1) Ingredients prescription

[0045] Dye liquid: reactive dye 2g / l

[0046] Penetrant 3g / l

[0047] Defoamer

[0048] The dye solution and alkali agent (4:1) are mixed evenly through the buffer cylinder with a proportional metering pump and enter the rolling groove;

[0049] (2) Pad-rolling conditions: 7 liters of rolling bath liquid, one padding and one rolling at room temperature, the rolling margin is about 65%, and the uniform rolling mill is controlled between 1-1.3kg according to the variety;

[0050] (3) Vehicle speed: general varieties are above 60m / min, and those with more liquid absorption are about 30-40m / min;

[0051] (4) The maximum roll diameter is 1.4m. In order to prevent head prints, the entire shaft should be tightly wrapped;

[0052] (5) Rotating and stacking time depends on dye and dosage

[0053]

[0054] 2. Examples of reactive dye cold pad-batch dyeing process

[0055] Dyestuff: X g / l

[0056] Alkali agent: X-type dye soda ash 10-30g / ...

Embodiment 2

[0076] A cold pad-batch dyeing method for textile fabrics, the method includes three stages of immersion, stacking and washing;

[0077] The soaking stage includes the pre-treatment of cold pad stacking, semi-finished products and dyeing padding steps:

[0078] The stacking stage includes rolling and stacking steps;

[0079] The washing stage includes washing, soaping, rewashing and drying steps.

[0080] The pre-treatment of the cold-rolling pile includes the steps of padding with padding working fluid, coiling, stacking, alkali-distilled water washing and drying. The alkali-distilled water washing includes steaming (100° C., 2 to 4 minutes), hot water washing and cold water washing steps.

[0081] When using (destroying) the scouring and bleaching cold stacking method (over 20h at room temperature), the composition ratio (g / l) of the padding working fluid pre-treated by the cold rolling stack is: NaOH: 40; H 2 O 2 : 20; water glass: 3; chelating dispersant: 6 and scouring agent:...

Abstract

The invention discloses a cold pad-batch dyeing method for textile fabrics. The method includes three stages of immersion, stacking and water washing; the immersion stage includes the steps of cold pad-batch pretreatment, semi-finished products and dyeing and padding: The stacking stage includes rolling and stacking steps; the washing stage includes washing, soaping, rewashing and drying steps. The method of the present invention has advanced and reasonable processing flow and stable product quality. From the point of view of energy saving and environmental protection, the method is simple and reliable, has low infrastructure investment costs, high productivity, short cycle, high color fixation rate, and reduced sewage discharge. It is also a green dyeing and finishing method in the printing and dyeing industry.

Description

Technical field [0001] The invention relates to a method for dyeing and finishing textile fabrics by cold pad-batch dyeing, and belongs to the technical field of cold pad-batch dyeing production in the printing and dyeing industry that saves energy and reduces consumption and clean production. Background technique [0002] In recent years, with the continuous improvement of the people's material and cultural living standards, people have higher and higher requirements for the color and comfort of clothing. As a result, sales of solid-color fabrics increased significantly. As a result, reactive dyes with bright colors, complete chromatograms, cheap prices, simple processes, good levelling properties, and good washing fastness have become the most used dye varieties in the printing and dyeing industry. But everything has two sides. Reactive dyes have a low affinity for cotton fibers, and the dye uptake rate is lower than that of direct dyes and vat dyes. In order to increase the dy...
