Acid dye leveling agent integrating uniform dyeing, color increasing and color fixing and preparation method thereof

Abstract

The invention provides an acid dye leveling agent integrating uniform dyeing, color increasing and color fixing and a preparation method thereof. The acid dye leveling agent comprises, by weight parts, 10-30 parts of sodium lignin sulfonate, 15-30 parts of sulfonated castor oil, 20-40 parts of fatty acid amine polyoxyethylene ether, 5-25 parts of nano-attapulgite and 20-50 parts of addition agents. The preparation method comprises the steps: (1) adding a PH modifier to a solvent, evenly stirring the solvent so that the PH of the solvent is stable, slowing adding sodium lignin sulfonate, sulfonated castor oil and fatty acid amine polyoxyethylene ether, evenly stirring the solvent to fully dissolve the solvent, and performing defoaming to obtain mixed solution; (2) adding dispersing agent and the PH modifier into the solvent, adjusting the PH of the solution, adding nano-attapulgite, performing high-speed stirring until the nano-attapulgite is dispersed fully, and obtaining nano-attapulgite solution; (3) linearly slowing adding the nano-attapulgite solution into the mixed solution, evenly stirring the mixed solution, and obtaining the acid dye leveling agent integrating uniform dyeing, color increasing and color fixing.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to an acid dye leveling agent integrating leveling dyeing, color enhancement and color fixation and a preparation method thereof. Background technique: [0002] During the printing and dyeing process, uneven dyeing will seriously affect the quality and quality of the fabric. Therefore, in order to achieve uniform dyeing of the dye on the fabric without causing color stripes, stains and other defects, it is necessary to use a leveling agent. The function of the leveling agent has two aspects: slow dyeing and dyeing migration, so that the dye is slowly absorbed by the fiber, and at the same time, it promotes the migration of the dye in the dark part to the light part, and finally achieves the purpose of level dyeing. With the continuous development of science and technology, various new types of fibers have emerged. In order to comply with people's environmental...

AI Technical Summary

Problems solved by technology

[0006] Known from above-mentioned prior art, current acid dye leveling agent is seldom amphoteric compound type leveling agent, and the acid dye leveling agent prepared is mostly aimed at the dyeing levelness of single fiber, the chromatic aberration of fabric and the change of color. The study of saturation is not ideal, so it is necessary to develop an acid dye leveling agent that integrates level dyeing, color enhancement and color fixation
