 (C) coupling the color base fabric padding color reagent, diazo compounds in the color reagent and the backing fabric on the naphthol coupling reaction of the insoluble azo dyes, fabric showing a color, Custom Paint Checkered Flag This process is called color process.

Ar-N = of NCl of HO-Ar – of Ar-N = N-of Ar `-OH of NaCl H2O,

The strength of the color diazonium compounds and naphthol coupling ability with their chemical structure. Where the coupling ability of the chromophore, all kinds of color-based coupling, Promotional Yard Flags the coupling of the pH value can be controlled within 3 to 5, such as color-based red; coupling weak chromophore coupling pH control at 6 ~ 8, where Lamine blue salt VB.

Color fabric on the alkali soluble color reagent in order to maintain the pH value of the color does not exceed a certain limit, you can add the appropriate color liquid alkali agent. The alkali agent aluminum sulfate, Custom Paint Checkered Flag zinc sulfate, ammonium chloride. In order to make the pH value of the color within a certain range, but also add the appropriate buffer, such as acetic acid – sodium acetate.

(D) pad color process ice dye pad color, can be a dip rolling or two dip rolling, depending on the coupling rate of speed. Rolling groove volume should be small in order to ensure that the fresh color reagent. Custom Paint Checkered Flag The color reagent must be kept at a temperature below 15 , and avoid direct sunlight to prevent the decomposition of diazonium salt. Backing fabric by padding color is to take the air, so that the diazonium salt of the naphthol chromophore full coupling of the hair color.

Fabric by color first to take the air after a lot of cold water fully washed to remove most of the fabric on the residual diazonium salt to enter the hot washing and soaping. Zinc sulfate and other metal salts,

alkali agent, you must first 3 ~ 5 g / L sulfuric acid pickling and then cold water to fully rinse, and finally soaping. Insoluble azo dyes in the fabric surface floating color more soaping process is very important that only the full soaping the dyed fabrics in order to obtain a bright color and good light fastness, and to ensure a certain amount of rubbing prison degrees.

Hydrochloric acid and the amount of sodium nitrite in the color liquid prescription should be determined based on the amount of chromophore, the amount of sodium acetate by the amount of hydrochloric acid, acetic acid dosage is based on the concentration of the free base.

Color, where the Lamine blue salt VB salt, because of its bright color, Custom Paint Checkered Flag good color fastness, cheap, is widely used in production, and generally make the coat fabric dyeing. However, this blue cloth due to the impact of climate is humid and the sun, the course of time will produce the phenomenon of fading reddish, affecting the brightness of color. Be in pad color after steaming, and the corresponding measures can be improved to a certain extent.

Fourth, restore dyes

Vat dyes do not dissolve in water, staining in alkaline strong in the solution of reductive dissolution of the sodium salt of leuco dye fiber can revert to insoluble dyes and color lakes, after oxidation, while the solid in the fiber.

The vat dye is the dye in the performance excellent dye. According to their chemical structure can be divided into two categories of the indigo classes and anthraquinone. Chromatogram than the whole, the bright color, soaping, light fastness is relatively high, but more expensive, some yellow, orange and other color photosensitive brittle damage phenomenon, making the application subject to certain restrictions.

(A) restore the process of dyeing vat dyes staining, Outdoor Flags For Sale  can be disseminated, Custom Paint Checkered Flag jigger or padding. General yarn and knitted fabrics mostly mostly with jigger and pad dip, woven fabric, generally include the following four basic processes.

A dye vat dyes restore process is to restore the generation process of the dye leuco are generally carried out in alkaline medium. The molecular structure of the vat dyes containing at least two carbonyl groups (= C = O), they are strong reducing agent dithionite sulfate sodium (commonly known as sodium hydrosulfite) the role of the carbonyl is reduced to the hydroxyl (-OH). The chemical properties of sodium hydrosulfite is very lively, Custom Paint Checkered Flag under alkaline conditions, even very low temperatures, can produce a strong reduction of vat dyes to be reduced to the leuco acid.
