Abstract

The invention relates to an organic dye for fabric dyeing and a preparation method thereof. The organic dye is prepared from the following components in percentage by weight: 3-8% of a dyeing agent, 3-5% of a leveling agent, 1.3-1.6% of a semi-emulsion thickening agent, 20-25% of a cosolvent, 2-5% of a dispersing agent, 1-2% of a stabilizer and the balance of water, the coloring agent is organic dye; the leveling agent is an isocyanate compound; the semi-emulsion thickening agent is prepared from a thickening agent and an emulsifying agent according to the weight ratio of 50: (2-3); the cosolvent is an organic solvent; the dispersing agent is an anionic dispersing agent or an amphoteric dispersing agent. The preparation method comprises the following steps: S1, preparing a semi-emulsion thickening agent; s2, dye grinding; s3, preparing the organic dye. The dye has the advantages of being wide in application range, long in storage time and good in stability.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to an organic dye for fabric dyeing and a preparation method thereof. Background technique [0002] Dyes are substances that can color fibers and other materials. Dyes are divided into two categories: natural and synthetic. Dyes are colored substances. But a colored substance is not necessarily a dye. Dye is a substance that can make a certain color adhere to the fiber, and it is not easy to fall off and change color. Dyes are usually soluble in water, and some dyes require a mordant to make the dye stick to the fiber. Archaeological data show that dyeing techniques have a history of more than 5,000 years in India and the Middle East. The dyes at that time came from animals, plants or minerals and were rarely processed. [0003] Color fastness is one of the important quality indicators to measure the dyed finished product, the color fastness of the color that is easy to ...
