Description
Technical Field
The invention belongs to the technical field of textile printing and dyeing, and particularly relates to white-proof slurry for physical printing prevention of reactive dyes and a preparation method thereof.
Background
The reactive dye is an important technical means for enriching product types and obtaining various styles and patterns in the printing field. The printing of fine flower-shaped outlines is realized by the anti-printing of the reactive dye, and the anti-printing ink plays an important role in the visual perception and the style diversity of the printing.
At present, the printing prevention of the reactive dye mainly takes organic acid, sodium sulfite and the like as printing prevention agents, and the printing prevention effect is achieved by a chemical method. The reactive dye can react with the fiber under an alkaline condition (pH is 8-11) to form a firm chemical bond, and the color fixing condition of the reactive dye is destroyed by commonly adopted organic acids such as citric acid, tartaric acid and other substances with weak acidity. However, because acid damages natural fiber, the use amount of organic acid cannot be too high, and simultaneously reactive dye can be absorbed by the fiber, and the reactive dye has a certain dyeing effect even if the reactive dye does not react with the fiber, so that the method easily causes incomplete printing prevention and influences the printing fineness. The sodium sulfite is a commonly used chemical auxiliary agent for the current anti-printing, can react with the vinyl sulfone active group first, has a reaction rate faster than the reaction of the fiber and the vinyl sulfone active group, and can not be combined with the fiber, but has larger anti-printing limitation, mainly has an anti-printing effect on the active dye with the vinyl sulfone active group, and also has the defect of poor anti-printing effect on turquoise blue in the vinyl sulfone active dye. Meanwhile, the chemical agent is used for preventing the reactive dye from printing, and the phenomenon of outline edge halation also occurs. In addition to the above problems, the anti-printing paste prepared from organic acid and sodium sulfite can not be stored for a long time in a production environment, is easy to decompose and lose efficacy, and causes great pollution to the environment.
