Preparation method of reactive dye dyeing accelerating functional agent

Abstract

The invention provides a preparation method of a reactive dye dyeing accelerating functional agent. The preparation method comprises the following steps of (1) treating porous silicon micropowder by an acid solution; (2) modifying the porous silicon micropowder prepared in the step (1) by 2,3-epoxypropyltrimethylammonium chloride to obtain modified porous silicon micropowder; (3) mixing the modified micropowder prepared in the step (2), trifluoroacetic acid, sodium alginate, sodium polyacrylate, polyacrylamide, sodium hexametaphosphate, guar gum, ethylene glycol dimethyl ether, an emulsifier and water; and performing heating and stirring, and dispersion by a high-speed dispersing machine to obtain the dyeing accelerating functional agent. The dyeing accelerating functional agent prepared by the method plays an important role in the dyeing process of reactive dyes; the dye uptake of the dyes is improved; the color depth of the dyed fabric is increased; the dyed fabric has high washing fastness; and the fixation performance of the dye is good, so that the reactive dye dyeing accelerating functional agent prepared by the preparation method has an important application value in the textile field.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation method of a reactive dye dyeing accelerator functional agent. Background technique [0002] Due to the different components of different fabrics and the different structures of different components, the dyeing amount of dyes is also different, and it is easy to cause color difference when dyeing, especially when the color is light, the color difference is more serious. The traditional improvement method is to prolong the dyeing time. A large amount of leveling agent, together with auxiliary processes such as padding to enhance the dyeing effect, requires a large amount of neutral inorganic salts in the dyeing process of reactive dyes to improve the dyeing rate and fixation rate of dyes, because inorganic salts are easy to Water sources are polluted, water salinization and land salinization destroy the ecological balance, causing great harm to the natura...

[0002] Due to the different components of different fabrics and the different structures of different components, the dyeing amount of dyes is also different, and it is easy to cause color difference when dyeing, especially when the color is light, the color difference is more serious. The traditional improvement method is to prolong the dyeing time. A large amount of leveling agent, together with auxiliary processes such as padding to enhance the dyeing effect, requires a large amount of neutral inorganic salts in the dyeing process of reactive dyes to improve the dyeing rate and fixation rate of dyes, because inorganic salts are easy to Pollution of water sources leads to salinization of water and land, which destroys the ecological balance and causes great harm to the natural environment, and the soluble salt in sewage is difficult to deal with

[0003] As the country's requirements for environmental protection and energy conservation and emission reduction in various industries are getting higher and higher, the traditional dyeing process with high energy consumption, water consumption and high pollution can no longer meet the requirements of the modern textile industry.
