Problems solved by technology

[0011] In order to solve the above-mentioned technical problems, the dyeing method provided by the present invention is to realize the deep color dyeing method of fabrics with polymer materials, avoiding the need to add a large amount of salt and alkali to promote dyeing and color fixation due to reactive dyes. , causing the dyeing wastewater to become saline sewage, resulting in high salt content in the sewage. The result of direct discharge of high-salt wastewater is the phenomenon of polluting the water body and making the land salinized.

Embodiment 1

[0041] Taking the thin cotton fabric as an example, the printing and dyeing method of the present invention is specifically as follows:

[0042] Configure dye working solution→configure special color fixing agent working solution→proportion pump 4:1→configure into dyeing working solution→pad dyeing working solution (rolling rate 55-65%)→drying (80°C, keep the cloth surface containing Moisture rate 6.5%-8.5%)→Steam fixation (102℃x60-80 seconds)→Two compartments of cold water washing (20-30℃)→Two compartments of warm water washing (40-50℃)→Three compartments of soaping (soaping Lotion 4g / L, temperature 95-98°C) → two compartments of warm water (70-80°C) → one compartment of cold water (30-40°C) → drying;

[0044]

[0045] The composition of the special color fixing agent: 750 parts of sodium metasilicate pentahydrate, 250 parts of urea, and 2 parts of sodium dodecylbenzenesulfonate, all in parts by weight; the reactive dye is a commonly used common dy...

Embodiment 2

[0071] Take thick and thick fabric as example, illustrate technique of the present invention, specifically as follows:

[0072] 1 chemical material: high level tank dye and special color fixing agent (735 parts of sodium metasilicate pentahydrate, 260 parts of urea, 2 parts by weight of sodium dodecylbenzenesulfonate) separate chemical material, reactive dye and anti-swimming agent cable Lideco V is converted into a chemical tank, and the special color fixing agent is separately converted into a chemical tank. The dosage of the special color fixing agent is: light color 28g / L, medium color 32g / L, dark color 38g / L. Through the proportional pump according to the ratio of dye: special color fixing agent of 4:1 (volume) is added to the rolling tank through the one-way valve, and the working error of the proportional pump is not more than 2% within 10 hours;

[0073] 2 Rolling material: The semi-finished fabric is dipped and rolled in the rolling material tank, and then passed thro...

Embodiment 3

[0079] In the color fixing agent, 740 parts of sodium metasilicate pentahydrate, 260 parts of urea, 2 parts of sodium dodecylbenzenesulfonate, and the rest are the same

Abstract

The invention relates to a saltless dyeing method with pure cotton fabric deep shade reactive dyes and realized by utilizing the macromolecular material. The method has the characteristics that inorganic salt is not used for accelerating dyeing, inorganic salt discharge in waste water is greatly reduced compared with the traditional printing and dyeing technology, and environmental friendliness and clean production are realized. The special color-fixing agent provided by the invention for fixation of reactive dyes of the macromolecular material has solubilizing and dispersing effects, aggregation of dyes is effectively inhibited, color points and color spots which are produced due to condensation of the dyes are reduced, and the color-fixing agent has good dispersion and suspension effects, so that stability of working solution and uniform distribution of the dyes on a fabric are effectively enhanced, and a fully dyed fabric is obtained.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing, and in particular relates to a fabric dyeing method realized by using polymer materials. Background technique [0002] With the development of scientific and technological progress and the improvement of people's living standards, the requirements for textiles are getting higher and higher. The constant pursuit of green environmental protection, safety and ecology, and clean production and environmental friendliness have become people's urgent yearning and pursuit. In addition, the conventional dyeing process is long, the amount of inorganic salt is large, the cost is high, the process control point is difficult, the probability of quality problems is high, and the difficulty of sewage treatment is increased; the current textiles tend to be small batches and more varieties, high color fastness , short process and fast delivery, while environmental regulations are becoming more and mor...
