These are based on mono chlorotriazene. They are characterized by moderate reactivity characterizes require strong fixation conditions and are primarily used for printing and continuous dyeing. A great choice is to select the customers according to their needs.

Reactive dyes are a class of highly colored organic substances, used primarily for dyeing textiles, adhering to their substrates by a chemical reaction that forms a covalent bond between the dye molecule and the fiber. The dye thus becomes a part of the fiber and is less likely to be removed by washing, which are dyes that attach by adsorption.
