Reactive dyes dyeing theory

Author:Huaxia TechnologyHits:Published time:2021-10-09

The reason why the dyes used in the dyeing machine can dye so quickly in a short time is that there are reactive groups in the reactive dyes that can react with the fiber.

The structure of reactive dyes is different from other dyes. Their structure can be expressed by the following general formula: s-d-b-r, in which s is a water-soluble group; D is the dye matrix; B is bridge foundation; R is the active group. Reactive group is the core of reactive dyes. Dyeing is chemically bonded with fibers through it, which determines the reactive activity, fixation rate, color fastness and application conditions of reactive dyes. The dyeing of reactive dyes is generally divided into three stages: dyeing, fixation and post-treatment.
