Embodiment 1-20

[0034] Wherein, the preparation method of the disperse dye composition described in embodiment 1-8 and comparative example 1-2 is preferably any in the following methods:

[0035] Method 1: After mixing all the components with water according to the mass percentage, carry out protonation treatment, and spray dry;

[0036] Method 2: After mixing each component with water, carry out protonization treatment, spray drying, and then mix according to mass percentage.

[0037] Wherein, the preparation method of the disperse dye composition described in embodiment 9-20 and comparative example 3-6 is preferably any in the following methods:

[0038] Method A: After mixing all components with additives and water according to the mass percentage, carry out protonation treatment and spray drying;

[0039] Method B: After mixing each component with additives and water, carry out protonation treatment, spray dry, and then mix according to mass percentage.

Embodiment 12

[0055] Example 12 and Comparative Example 3 are shown in Table 4 below for alkali-resistant shades.

[0056] Each get X gram (X refers to the quality under the same color light intensity with contrast sample) the disperse dye composition that embodiment 12 and comparative example 3 make, be dispersed in 500 milliliters of water, mix with 60 milliliters of water after imbibing 20 milliliters. Use acetic acid to adjust the pH of the dyeing bath to 4, heat up to 70°C and put 2 grams of polyester cloth into it for dyeing, heat up to 130°C in 30 minutes, keep warm for 30 minutes, cool to 90°C to test the dyed cloth sample.

[0057] Using AATCC 6-2001, test the acid and alkali resistance of the above cloth samples. The test results are as follows:

Abstract

The invention discloses a disperse dye composition and a preparation method and application thereof. The disperse dye composition comprises the following components by mass percent: 5-95% of a component A and 5-95% of a component B. The preparation method is one of the two: a method I: mixing all the components with water by mass percent, performing protonation treatment, and conducting spray-drying; and a method II: after mixing the components with water, performing protonation treatment, conducting spray-drying, and then performing mixing by mass percent. The disperse dye composition is resistant to water washing, high in sublimation fastness, and resistant to friction, alkaline and hydrogen peroxide washing, and has a very high practical value.

Description

technical field [0001] The invention relates to a disperse dye composition, its preparation method and application. Background technique [0002] With the development of polyester fiber in recent years and the improvement of people's requirements for textiles, the public has put forward higher requirements for the dyeing performance, energy saving and environmental protection performance of dyes, and the corresponding fastness of dyes must be improved. For complex dyes, the application performance of their dyeing compatibility still cannot fully meet the demand. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a disperse dye composition, its preparation method and application in order to overcome the defects that the existing application performance of dyeing compatibility still cannot fully meet the requirements. The disperse dye composition has the advantages of washing resistance, high sublimation fastness, ab...
