Abstract
The application relates to the technical field of textiles, and particularly discloses a cloth printing and dyeing process, which comprises the following steps of: bleaching the grey cloth by using hydrogen peroxide solution, and then pretreating the grey cloth by using ethanol and a silane coupling agent; then mixing nano zinc oxide, succinic acid and lactic acid for reaction, adding reactive dye, carboxymethyl chitosan, organic bentonite, tea tree oil and deionized water, and uniformly mixing to obtain a dye liquor; dyeing and fixing the grey cloth by adopting a one-bath method; finally, raw materials such as soaping enzyme, polyvinylpyrrolidone, dodecyl dihydroxyethyl betaine and sophorolipid are prepared into soaping liquid, and the grey cloth is washed by water after soaping; the process has the advantages of simple operation method, low printing and dyeing cost, improved dye uptake and color fastness, no addition of salt or alkaline agent in raw materials, and reduced environmental pollution, and is an environment-friendly cloth printing and dyeing process.
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 takes up a significant position in the textile industry, with respect to the overall quality of the fabric. The quality of the print directly affects the appearance of the fabric, and therefore the choice of dye is also important. At present, the reactive dye has the advantages of complete color spectrum, bright color, good uniformity, low cost and the like, and is widely applied to the dyeing and printing technology of cotton, hemp, viscose, silk, wool and other fibers and blended fabrics.
The reactive dye is an anionic dye, and in the dyeing process, the negatively charged reactive dye can generate repulsive force with the negative charge on the surface of the fiber, so that the combination 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, reactive dyes are readily soluble in water and hydrolyze in water, resulting in reduced dye availability. In the related art, a cationic modifier is added in the dyeing process to eliminate the repulsive force effect between the dye and the fiber, and salt and an alkaline agent are added to inhibit the hydrolysis of the reactive dye. 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; salt and alkaline agents are eventually discharged into rivers and soil, causing serious environmental pollution.
Therefore, the dye-uptake and the color fastness of the reactive dye are improved, and the content of salt and alkaline agent in dyeing wastewater is reduced, which is a problem to be solved in the dyeing process of the reactive dye at present.
Disclosure of Invention
The application provides a cloth printing and dyeing process, which aims to solve the problems of low dye-uptake rate, low color fastness, high salt and alkali agent content in dyeing wastewater and the like of the existing 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 stage adopts a dye liquor which 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, the nano zinc oxide can react with the organic acid to generate Zn 2+, and the generated Zn 2+ not only can form a complex with groups such as-OH, -NH-and the like contained in the dye, but also can form a complex with-OH and the like in the fiber. Therefore, zn 2+ is used as a bridge, and dye molecules and fibers are combined through coordination bonds, so that the dye uptake of the dye is improved, and the dyeing fastness of the dye is improved.
Preferably, the organic acid is prepared by compounding succinic acid and lactic acid in a mass ratio of 3-7:5.
