Problems solved by technology

At present, many dyes cannot meet the requirements in terms of performance. Especially in the current environment of rapid economic development, the dyeing speed of dyes is not fast enough, which increases the production cost. In addition, the alkali resistance of the dyed fabric is not good. Strong, prone to disadvantages such as fading

Abstract

The invention belongs to the technical field of dye and relates to a disperse dye composition and particularly relates to an alkali-resistant fast-dyeing disperse dye. The alkali-resistant fast-dyeing disperse dye consists of the following components in percentage by mass: 40-60% of a component A, 20-30% of a component B, 15-30% of a component C, 1-5% of a component D and the balance of a dispersing agent. The alkali-resistant fast-dyeing disperse dye provided by the invention has the advantages that the dyeing composition is prepared according to the specific mixing ratio; since each component has relatively strong alkali resistance, the performance of the components after combination does not change, and the dye with relatively strong alkali resistance can be obtained; and through dyeing with the conventional method of the industry, the dyed fabric with full hue can be obtained while the dyeing time is shorter and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of dyes, and relates to a disperse dye composition, in particular to an alkali-resistant fast dyeing disperse dye and a preparation method thereof. Background technique [0002] Disperse dyes are a class of non-ionic dyes with low water solubility. It was first used for the dyeing of acetate fiber, known as acetate dye. With the development of synthetic fibers, nylon and polyester have appeared one after another, especially polyester, because of its high alignment, less fiber voids, and strong hydrophobicity, it is necessary to expand the fiber with a carrier or under high temperature and thermal melting, so that the dye can enter Fiber and dyed. With the rapid development of polyester new fibers in recent years and the increase in people's demand for textiles, correspondingly, the dyeing performance and environmental protection performance of the dye itself have also put forward historically high requirem...
