Embodiment 1

[0084] The blue disperse dye composition that is made up of component A of 46 gram formula (I), component B of 14 gram formula (II), component C of 40 gram formula (III-1) and 50 gram imported lignin 85A 100 grams of dispersant MF, add 400 grams of water and stir well, grind and disperse and dry to obtain 300% blue disperse dyes, which can obtain bright blue fabrics with excellent fastness.

Embodiment 2-11

[0099] According to the same method of embodiment 1, according to the composition formula in table 3, blue disperse dyes are made as shown in table 3.

[0100] Table 3 Weight unit: grams

[0101]

[0102]

[0103] Adopt the method identical with embodiment 1 to carry out performance test to the blue disperse dye of embodiment 2-11. Observe the shade of the cloth sample, refer to GB / T2403-2014 and GB / T2400-2006 to measure their pH value adaptation range and compatibility, the results are shown in Table 4;

[0104] Table 4

[0105]

[0106]

[0107] From the data in Table 4, it can be seen that the blue disperse dye prepared by the method of the present invention has the advantages of wide pH range and good compatibility.

Abstract

The invention relates to a blue disperse dye composition and a blue disperse dye. The composition comprises a component A, a component B and a component C composed of one or more compounds. The blue disperse dye prepared through using the composition has bright color and light, has the obvious advantages in strength, buildup, sublimation fastness and washing fastness, and also has the advantages of wide pH value adaptation range and good compatibleness.

Description

technical field [0001] The invention relates to a blue disperse dye composition, a blue disperse dye and a preparation method and application thereof. The blue disperse dye is suitable for dyeing and printing of polyester and its blended fabrics. Background technique [0002] C.I. Disperse Blue 56 is a sapphire blue disperse dye that is widely used in disperse dyes. The fabric dyed with this dye is bright and bright in color and has high light fastness. Problems such as low strength, poor lifting force, poor dyeing depth, and large environmental pollution. Contents of the invention [0003] In order to overcome the deficiencies of C.I. Disperse Blue 56, the invention provides a blue disperse dye composition, the blue disperse dye prepared by the blue disperse dye composition has bright color, good lifting power, wide range of pH value adaptation, and compatibility Good, the fastness performance is superior. [0004] The present invention provides a kind of blue disperse...
