Production method for reactive dye

Abstract

The invention discloses a production method for reactive dye. The production method uses a production device for the reactive dye. The production device comprises a machine body fixed on a bracket. The machine body is internally provided with a first sliding chute which is leftwards and rightwards extended and provided with an upward opening. The right side of the upper end of the machine body isintegrally provided with a top base which is upwards extended. The top base is internally provided with a second sliding chute which is provided with a downward opening and communicated with the firstsliding chute. The upper end face of the top base is fixedly provided with a cylinder body. The top base is further internally provided with a feeding groove communicated with the cylinder body and the first sliding chute. The first sliding chute is internally provided with a reaction cylinder which can be leftwards and rightwards slid. The reaction cylinder is internally provided with a cylindercavity with an upward opening. The end wall of the front end of the first sliding chute is internally and symmetrically provided with a first guiding channel which is leftwards and rightwards extended. The first guiding channel is internally and slidably provided with a first guiding block fixedly connected with the reaction cylinder. The first guiding block is internally provided with a first threaded rod in screw-thread fit.

Description

technical field [0001] The invention relates to the technical field of dye production, in particular to a production method of reactive dyes. Background technique [0002] Reactive dyes, also known as reactive dyes, are a new type of water-soluble dyes that appeared in the 1950s. Reactive dye molecules contain active groups that can react with hydroxyl groups in cellulose and amino groups in protein fibers. A covalent bond is formed, resulting in a "dye-fiber" compound. Reactive dyes have the characteristics of bright color, good level dyeing, simple dyeing method, high color fastness, complete color spectrum and low cost. They are mainly used in the dyeing of cotton, hemp, viscose, silk, wool and other fibers and their blended fabrics. And printing, in the production process of reactive dyes, a neutralizing solution is often added to neutralize the mixed solution, and a stirring device is used to stir the mixture during the neutralization reaction, while the traditional ...

Reactive dyes have the characteristics of bright color, good level dyeing, simple dyeing method, high color fastness, complete color spectrum and low cost. They are mainly used in the dyeing of cotton, hemp, viscose, silk, wool and other fibers and their blended fabrics. And printing, in the production process of reactive dyes, a neutralizing solution is often added to neutralize the mixed solution, and a stirring device is used to stir the mixture during the neutralization reaction, while the traditional stirring device is generally soaked in In the mixed liquid, it is enough to turn on the motor when it needs to be used, but the stirring rod and the stirring shaft in this stirring device will chemically react with the neutralizing liquid or the mixed liquid, its service life is low, and there are potential safety hazards
