Embodiment 1

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

Embodiment 2-11

[0099] According to the same method as Example 1, according to the composition formula in Table 3, blue disperse dyes were prepared as shown in Table 3.

[0100] Table 3 Weight unit: grams

[0101]

[0102]

[0103] The performance test of the blue disperse dyes of Examples 2-11 was carried out by the same method as that of Example 1. Observe the color and light of the cloth samples, and refer to GB / T2403-2014 and GB / T2400-2006 to determine their pH adaptability range and compatibility. The results are shown in Table 4;

[0104] Table 4

[0105]

[0106]

[0107] It can be seen from the data in Table 4 that the blue disperse dye prepared by the method of the present invention has the advantages of wide adaptability of pH value and good compatibility.

Abstract

The invention discloses 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 from the composition is bright in color, has obvious advantages in strength, elevating power, sublimation fastness and washing fastness, and has the advantages of being wide in pH value application range and high in compatibility.

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 color of the fabric obtained by dyeing with this dye is bright and bright, and the light fastness is high, but it also has significant shortcomings, such as high dye price, dyeing Low strength, poor lifting force, poor dye depth, and large environmental pollution. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiency of C.I. disperse blue 56, the present invention provides a blue disperse dye composition. The blue disperse dye prepared by the blue disperse dye composition has bright color and light, good lifting power, wide range of pH value adaptation, and compatibility. Good, the fastnes...
