Preparation method of reactive dye

Abstract

The invention discloses a preparation method of reactive dye. A reactive dye preparation device applied to the method comprises a machine body fixed on a support, the machine body is internally provided with a first sliding groove, the first sliding groove with an upward opening extends leftwards and rightwards, a top seat extending upwardly is integrally arranged on the right side of the upper end of the machine body, and a second sliding groove with a downward opening is formed in the top seat and is communicated with the first sliding groove; a cylinder is fixedly mounted on the upper end face of the top seat, a feeding groove communicated with the cylinder and the first sliding groove are formed in the top seat; a reaction cylinder capable of sliding leftwards and rightwards is mountedin the first sliding groove; a cylinder cavity with an upward opening is formed in the reaction cylinder; first guide grooves extending leftwards and rightwards are symmetrically formed in the frontend wall of the first sliding groove, and first guide blocks fixedly connected with the reaction cylinder are slidably arranged in the first guide grooves; first threaded rods are fittingly mounted inthe first guide blocks.

Description

technical field [0001] The invention relates to the technical field of dye production, in particular to a preparation 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 s...

Problems solved by technology

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
