Description
Technical Field
The application relates to the technical field of textiles, in particular to a cloth printing and dyeing process.
Background
The printing and dyeing process plays a significant role in the textile industry and is related to the comprehensive quality of the fabric. The quality of the printing quality directly affects the appearance of the fabric, and therefore, the choice of dye also appears to be of great importance. At present, the reactive dye has the advantages of complete color spectrum, bright color, good leveling property, low cost and the like, and is widely applied to the printing and dyeing process of fibers such as cotton, hemp, viscose, silk, wool and the like and blended fabrics.
The reactive dye is an anionic dye, and during the dyeing process, the negatively charged reactive dye can generate repulsion with the negative charges on the surface of the fiber, so that the binding rate of the dye and the fiber can be reduced, and the dye uptake and the color fastness of the reactive dye are not high. In addition, the reactive dyes are readily soluble in water and undergo hydrolysis in water, resulting in a decrease in the utilization of the dye. In the related art, a cationic modifier is added in the dyeing process to eliminate the repulsive force between the dye and the fiber, and the hydrolysis of the reactive dye is inhibited by adding salt and an alkaline agent. The addition of the cationic modifier improves the dye uptake to a certain extent, but the color fastness of the dye is still not ideal; the final discharge of salts and alkalis into rivers and soils causes serious environmental pollution.
Therefore, the problems that the dye uptake and the color fastness of the reactive dye are improved, and the content of salt and an alkaline agent in dyeing wastewater is reduced are to be solved urgently in the dyeing process of the reactive dye at present.
Disclosure of Invention
In order to solve the problems of low dye uptake, low color fastness, high content of salt and alkaline agent in dyeing wastewater and the like of the conventional cloth printing and dyeing process, the application provides a cloth printing and dyeing process.
The application provides a cloth printing and dyeing process, which adopts the following technical scheme:
the cloth printing and dyeing process specifically comprises three stages: a pretreatment stage, a dyeing stage and a post-treatment stage; the dyeing liquid is selected in the dyeing stage and comprises the following raw materials in parts by weight: 20-30 parts of reactive dye, 10-15 parts of nano zinc oxide, 12-16 parts of organic acid and 50-60 parts of solvent.
By adopting the technical scheme, the dye liquor is prepared by uniformly mixing the reactive dye, the nano zinc oxide, the organic acid and the solvent, and the nano zinc oxide can react with the organic acid to generate Zn 2+ Zn formed 2+ Not only can form a complex with-OH, -NH-and other groups contained in the dye, but also can form a complex with-OH and other groups in the fiber. Therefore, with Zn 2+ The dye is a bridge, and dye molecules are combined with fibers through coordination bonds, so that the dye uptake of the dye is improved, and the dye fastness of the dye is improved.
Preferably, the organic acid is obtained by compounding succinic acid and lactic acid in a mass ratio of 3-7: 5.
By adopting the technical scheme, the succinic acid and the lactic acid are selected to be compounded to prepare the organic acid, and the succinic acid and the lactic acid can ionize H + React with nano zinc oxide to generate Zn 2+ And the succinic acid has an excellent anti-shrinkage function, and the lactic acid can increase the glossiness and softness of the grey cloth. The organic acid prepared by compounding the two is added into the dye liquor, so that a large amount of Zn can be generated in the dye liquor 2+ The dyeing rate of the dye is improved, the softness of the grey cloth can be increased, and the phenomenon that the grey cloth is easy to shrink is reduced.
Preferably, the solvent is prepared by compounding tea tree oil and deionized water in a mass ratio of 6-10: 1.
