what are fiber reactive dyes
Jul 26, 2018

The reactive dyes are composed of the parent dye, the linking group and the active group, so that they can form a strong covalent bond with the fibers during use, and have a series of characteristics unmatched by other cellulose fiber dyes. The development and use of dyes for the use of dyes in the fiber is prominently manifested in the following four aspects:

(1) Reactive dyes are one of the best alternatives to banned dyes and other types of cellulose dyes such as sulphur dyes, ice dyes and vat dyes.

(2) Reactive dyes can achieve high levels of fastness, especially wet fastness, using an economical dyeing process and simple dyeing operations.

(3) The reactive dye has wide chromatogram, bright color, excellent performance and strong applicability, and its hue and performance are basically compatible with the market requirements for fiber and clothing.

(4) Reactive dyes are suitable for printing and dyeing of new cellulose fiber products such as Lyocell fibers.
