1. Overview of acid dyes Acid dyes refer to the acid group in the dye molecules, also known as anion dye, which can be combined with amino groups in protein fiber molecules with ion bonds and applicable under acidic, weak acids or neutral conditions. Read More

Many people always confuse dyeing and printing, but in fact there are obvious differences between the two. Next, let me give you a popular science about the difference between dyeing and printing. 1. The difference between dyeing and printing has the following eight points:1. Printing is better at c Read More

In the textile industry, the whiteness of the fiber itself often does not meet people's aesthetic requirements. Especially natural fibers, because the growth environment is different from the growth cycle, its whiteness difference is very different. White substances are generally absorbed slightly i Read More

El mejor efecto de superficie de tela de la tela significa que la tela no producirá arrugas que son difíciles de eliminar debido a la fuerza mecánica externa u otros factores, y el fenómeno de los rasguños y la vellosidad por fricción debido a la fuerza mecánica externa. Los tejidos de punto de algodón, especialmente las variedades de un solo lado, son propensos a las arrugas que son difíciles de eliminar después del acabado cuando se decapan y blanquean en forma de cuerda. También se les llama "arrugas muertas". Este es un problema común de calidad del producto en el método de lavado y blanqueo de las máquinas de teñir. . Read More

Acid dye refers to a dye that contains acid groups in dye molecules that can be combined with amino groups in protein fiber molecules with ion bonds and applicable to acidic, weak acids or neutral conditions.Its structure is mainly nitrogen and 为, and a few are aromatum methane structures.

Cellulose fibers such as pure cotton are usually dyed with anionic water-soluble dyes such as direct dyes and acid dyes. These dyes have a complete color spectrum and bright colors. But, because the structure of this type of dye has a water-soluble group, therefore, the dye is hydrophilic, and when Read More

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 Read More

Because at 130 ℃, the dyeing percentage of disperse dyes is the highest, with bright color, level dyeing and less floating color. 1) If the temperature is too high, the dye is easily decomposed and the fiber is easily damaged.2) If the temperature is too low, the dyeing rate is low and the dye penet Read More

Estructura del colorante (pigmento), la estructura del colorante se divide básicamente en tres partes "grupo raíz cromóforo" "grupo raíz de reacción (unión)" "grupo raíz de conexión" Read More

Solvent dye is a type of dye that can be dissolved in organic solvents. It is a very common type of dye. It is insoluble in water and can only be dissolved in organic solvents or oils. Read More

Solvent dye was originally named because it can be dissolved in various organic solvents. ) The dye in) is called Oil Dye (Oil Dye), and the dyes that can dissolve the polar solvents (ethanol, acetone) are called alcohol soluble dye. Read More
