Abstract

The invention relates to high-fastness disperse dye composition as well as a preparation method and an application thereof. The high-fastness disperse dye composition comprises two compounds with two different structures in formula I, two compounds with two different structures in formula II, a compound shown in the formula III and a compound shown in the formula IV. The preparation method comprises steps as follows: the compounds shown in the formulas I, II, III and IV are mixed uniformly with an auxiliary, ground and subjected to spray drying, and the high-fastness disperse dye composition is obtained. The high-fastness disperse dye composition is applied to dyeing of hydrophobic fibers or fiber blended fabric. The high-fastness disperse dye composition has good fixation, leveling property, washing fastness, rub fastness, perspiration fastness, sublimation fastness and build-up property and also has very good light fastness, and the preparation method is simple in process, low in cost and has good application prospect.

Description

technical field [0001] The invention belongs to the field of non-ionic dyes, and particularly relates to a high-fastness disperse dye composition and a preparation method and application thereof. Background technique [0002] Disperse dyes are a class of non-ionic dyes with low water solubility. Disperse dyes were first used in the dyeing of acetate fibers, called acetate dyes. With the development of synthetic fibers, nylon and polyester appeared one after another, especially polyester, because of its high alignment, less fiber voids, and strong hydrophobicity. The fiber needs to be expanded under high temperature and hot melt, so that the dye can enter the fiber and be dyed. With the development of synthetic fibers, people also put forward new requirements for dyes. The previous dyes have application defects, such as low dye uptake and unacceptable fastness. [0003] Therefore, it is necessary to develop a new type of dye that can be applied to various types of fibers a...
