Because reactive dyes have the advantages of excellent performance, complete chromatogram and bright color and light, they have been widely used in medium and dark colors for many years. Now some light colors and light colors include difficult-to-dye light colors such as light rice and light gray. , Read More
Reactive dyes maintain an important position in dyes for cellulose fiber printing. The selection of such dyes should pay attention to three aspects: lifting power, compatibility and easy washing. The lifting force is printed with different dye concentrations to obtain different depths. After reachin Read More
Colorantes reactivos, también conocidos como colorantes reactivos. Una clase de tintes que reaccionan químicamente con las fibras durante el teñido. Read More
When the medium temperature reactive turquoise blue is dip-dyed, the reason why it is easy to produce color spots and stains is because the reactive turquoise blue has the defects of salt resistance and poor alkali dissolution stability. The medium-temperature active turquoise blue has good salt-dis Read More
2.3 Choose the right dyeing processThe dyeing process has a great influence on the color fastness of the dyed product. For example: Improper chemical materials, hydrolysis of dyes, and excessively hard water quality, resulting in dye aggregation and precipitation; improper color-fixing conditions, l Read More
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
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
Reactive dyes have a very good dissolution state in water. Reactive dyes mainly rely on the sulfonic acid group on the dye molecule to dissolve in water. -Ethylsulfonyl sulfate is also a very good solubilizing group.In the aqueous solution, the sodium ion on the sulfonic acid group and the -ethylsul Read More
Cotton fiber belongs to natural cellulose fiber. Cotton fabric has soft hand feel, good moisture absorption and air permeability and excellent wearing performance. As people pay more and more attention to wearing health and advocating nature, cotton fabric is loved by people. Reactive dyes are one o Read More
1 Choose the right dyeThe color fastness is closely related to the structure of the dye, and the selection of the dye should consider:① Strong reactivity between dyes and fibers;②High fixation rate;③It has better acid-base stability;④ The bond energy of the covalent bond of the dye-fiber is high, th Read More
1. Solubility High-quality reactive dyes have good water solubility in commercial applications. The solubility and the concentration of the dye solution are related to the selected bath ratio, the amount of electrolyte added, the dyeing temperature and the amount of urea and other factors. The react Read More
