Latest News and Updates on Textile Auxiliaries and Dyes

In the processing process in front of the cold rolling pile, its stacking time is a non -processing process in front of the cold rolling pile. The stacking time is a very important process parameter. , 12h, 16H, 24H, etc. As for why this stacking time is used, few people pay attention and think abou

Improving the wet rubbing fastness of reactive dyed deep-colored fabrics is one of the important ways to improve the quality of textiles and overcome the export barriers of textiles.The main reasons for the poor wet rubbing fastness of textiles are the floating color transfer of water-soluble dyes a

There are many varieties of reactive dyes, complete chromatography, simple process and relatively low price, so they are widely used. If color difference, color flower or cylinder difference occurs after dyeing, it is usually necessary to re-dye or repair the fabric. This not only affects the produc

The water solubility of reactive dyes is very good, but this characteristic is greatly affected by some substances or auxiliaries, which is often overlooked. In the dyeing process of reactive dyes, the problem of color difference or poor dyeing reproducibility occurs from time to time, which is ofte

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. ,

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

Colorantes reactivos, también conocidos como colorantes reactivos. Una clase de tintes que reaccionan químicamente con las fibras durante el teñido.

Reactive dyes, also known as reactive dyes. A class of dyes that chemically react with fibers during dyeing.

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

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

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

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
