Media Black PV, como un tinte de medios basado en ácido, tiene una amplia gama de aplicaciones en la cromatografía de lana debido a su excelente uniformidad y solidez a color, pero hay problemas como la contaminación ambiental y el daño fibroso causado por los agentes de alta temperatura y tintura.

Media black PV, as a acid -based media dye, has a wide range of applications on wool chromatography due to its excellent uniformity and coloring fastness.

La tinción de lana tradicional usa principalmente tintes ácidos, tintes de medios ácidos y tintes complejos de metal.

The traditional wool stain mainly uses acidic dyes, acid media dyes and metal complex dyes.

Cold -rolled pile staining, usually ethylene dyes. This is because the active base of the ethylene -type active dye is commonly used, which is very sensitive to alkali. In an alkaline bath, the reaction can be quickly disappeared, and the ethylene radon (-so2ch = CH2) with strong chemical activity c

Abstract Dyeing treatment can enrich the color of wooden materials and enhance its decorative effect and product value.

Although the fixing reaction rate is far greater than the hydrolysis reaction rate, if the process conditions are not controlled properly, such as the high pH value of the dyeing liquid or the temperature is too high.

1. Select reactive dyes with less floating color after dyeingFloating color is the main reason for the unqualified damp friction of dark color fabrics.Active dye -dye dyes include dyes that have been adsorbed on the fiber without reaction to the fiber, partial hydrolyzed dyes, and ethylene cymbal dy

1. dissolvedQuality activated dye products are well used in good water solution. The concentration of the solubility and the preparation of the dyeing solution is related to the selected bath ratio, the amount of electrolyte, the dyeing temperature, and the amount of urea. The solubility of active d

Before the cold rolling pile, the treatment should be in production:① Use a multi -rolling rolling method to ensure that the liquid penetration is evenly consistent. Generally, two grooves are used, and the front grooves are rolled with three rollers, and the rear grooves are used with two rollers.②
