Problems solved by technology

[0003] With the improvement of living standards, people pay more and more attention to aesthetics and taste. Although fur itself has good aesthetics, animal fur itself does not have a pearlescent effect. On the surface, sequins are woven on the animal fur to achieve a pearly and beautiful effect, but the animal fur is easily damaged during the weaving process, and after the clothes are washed many times, the woven sequins are easy to fall off, which affects the aesthetic effect of the fur.

Abstract

The invention relates to the field of dye preparation, and particularly discloses an acid dye and a preparation method thereof. The acid dye is prepared from the following raw materials of, in parts by weight, a ground color dye, an auxiliary agent, water, a thickening agent, a dispersing agent and modified mica sheet microcapsule particles, wherein the wall material of the modified mica sheet microcapsule particles is mainly prepared from rosin and a light diffusion agent, and the core material is mainly prepared from modified mica sheets. The preparation method comprises the following stepsof weighing the ground color dye, the auxiliary agent and a part of water, and stirring to obtain a primary mixture; weighing the thickening agent and the balance of water into the primary mixture, and stirring to obtain a mixture; and weighing the dispersing agent and the modified mica sheet microcapsule particles, putting the dispersing agent and the modified mica sheet microcapsule particles into the mixture, stirring to obtain acid dye liquid, drying and crushing to obtain an acid dye finished product. The acid dye has the advantages of pearly luster and high pearly luster washing fastness.

Description

technical field [0001] The application relates to the field of dye preparation, more specifically, it relates to an acid dye and a preparation method thereof. Background technique [0002] Fur is animal fur tanned with hair, used as clothing materials; common fox fur, mink fur, sheep skin and wolf skin. [0003] With the improvement of living standards, people pay more and more attention to aesthetics and taste. Although fur itself has good aesthetics, animal fur itself does not have a pearlescent effect. The sequins are woven on the animal fur on the surface to achieve a pearly and beautiful effect, but the animal fur is easily damaged during the weaving process, and after the clothes are washed many times, the woven sequins are easy to fall off, which affects the aesthetic effect of the fur. Contents of the invention [0004] In order to make the dye have the advantages of pearl luster and pearl luster with strong washing fastness, the application provides an acid dye a...
