Acid dyes, direct dyes and reactive dyes are all water-soluble dyes, and the output in 2001 was 30,000 tons, 20,000 tons and 45,000 tons respectively. Read More

1. Color fastness to light:The ability of the color of a textile to withstand exposure to artificial light. 2. Color fastness to washing:The resistance of the colour of textiles to the washing action of different conditions. 3. Color fastness to rubbing:The color resistance of textiles to rubbing ca Read More

First, in a color-fixing bath where salt and alkali coexist, the dye will have a higher concentration of electrolyte (salt, alkali), a greater salting-out effect, and the occurrence of "elimination reaction" of the active group of ß-hydroxyethyl sulfone sulfate. , the water-solubility of its own plu Read More

Migrating after dyeing means that after polyester is dyed with disperse dyes, when treated at high temperature (such as heat setting), disperse dyes can produce a kind of thermal migration due to the influence of additives. Thermal migration is a redistribution phenomenon of disperse dyes in two-pha Read More

El análisis del tinte original mencionado aquí se refiere a la prueba y el análisis de las propiedades físicas y químicas del tinte original para las necesidades del procesamiento del tinte. Después de años de investigación, se ha descubierto que el postratamiento no es un simple proceso físico. Antes de procesar el tinte, es necesario analizar muchos indicadores, como la intensidad, el tono, la hidrofilia, la forma de cristal, el nivel de energía y el contenido de impurezas del tinte original para determinar Proporcionar datos básicos con una tecnología de procesamiento razonable.

1. Test method for color fastness to lightThe light fastness test refers to placing the textile samples together with a set of blue wool standard samples under the artificial light source and exposing them to the specified conditions, and then comparing the two colors to evaluate the color fastness.

1. Methods and ways to improve the color fixing rateImproving the fixation rate of reactive dyes can be considered from the selection of dyes and the dyeing process: dyes with high directness and low reactivity have a large amount of adsorption by fibers and are not easy to be hydrolyzed. Fixation r Read More

Dye selection is an important link in process design, which not only affects the quality of dyed products, but also directly affects product cost and economic benefits. Read More

The dyeing and printing difficulties of spandex-containing textiles are more difficult than other textiles. On the one hand, spandex is easily damaged during dyeing and printing, and on the other hand, due to the special chemical structure of spandex, there is currently no ideal dye for it. Dyeing a Read More

Reactive dye molecules contain active groups, which can be covalently bonded with carboxyl, amino and hydroxyl groups on fibers, and can be used for fiber dyeing such as cellulose fibers, protein fibers and nylon. There are also some unsatisfactory aspects of reactive dyes, such as the fact that the Read More
