Problems solved by technology

[0002] With the continuous improvement of fabrics, ordinary all-polyester fabrics can no longer meet people's needs, while polyester-spandex and polyester-cotton blended fabrics are more and more popular due to their advantages of good wear resistance, good elasticity, no wrinkle, easy washing, and quick drying. More and more people favor it, but conventional disperse dyes stain spandex and cotton heavily, and cannot be used for dyeing and printing polyester-spandex and polyester-cotton blended fabrics. The development of new dyes is an urgent task for dye merchants

Embodiment 1

[0079] With 58 grams of component A of formula (1-1), 13.9 grams of formula (2-2) component B, 9.4 grams of component C shown in formula (3-4), 5.6 grams of formula (4-1 ) shown in Component D, 13.1 grams of Component E shown in formula (5) and 130 grams of imported lignin 85A, after adding 390 grams of water and blending, grinding with a sand mill, spray drying and making disperse dyes.

Embodiment 2

[0091] With 54 grams of component A of formula (1-2), 10 grams of formula (2-2) component B, 8 grams of component C shown in formula (3-2), 10 grams of formula (4-1 ) shown in component D, 18 grams of component E shown in formula (5) and 120 grams of diffusing agent CNF, after adding 390 grams of water and blending, grinding with a sand mill, spray drying to make disperse dyes.

Embodiment 3-14

[0102] 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.

[0103] Table 3 Weight unit: grams

[0104]

[0105]

[0106] The dyestuffs of Examples 3-14 were subjected to performance tests respectively.

[0107] The specific test method is as follows:

[0108] With reference to the method of GB / T2394-2006, take by weighing 0.5 gram of the disperse dye that embodiment 3-14 makes respectively in the 500ml volumetric flask, make disperse dye suspension, draw 60ml disperse dye suspension and mix with the water of 40ml, use Adjust the pH of the dyeing bath to 5 with acetic acid, and then raise the temperature to 60°C. 2g of polyester-spandex blended fabric is dyed under high temperature and high pressure. The temperature is raised to 130°C within 35 minutes, kept for 45 minutes, and cooled to 80°C for sampling.

[0109] Observe the color light of the cloth samples and measure their s...

Abstract

The invention discloses a disperse dye combination, disperse dye and a preparation method and application of the disperse dye. The disperse dye combination is prepared from a component A, a component B, a component C, a component D and a component E. The disperse dye prepared by the disperse dye combination not only has the advantages of good sublimation fastness and good washing fastness, but also has the obvious advantages in respects of light fastness and perspiration fastness.

Description

technical field [0001] The invention relates to a disperse dye composition, a disperse dye and a preparation method and use thereof. The disperse dye is suitable for dyeing and printing of polyester and its blended fabrics, especially suitable for dyeing and printing of polyester-spandex and polyester-cotton blended fabrics. Background technique [0002] With the continuous improvement of fabrics, ordinary all-polyester fabrics can no longer meet people's needs, while polyester-spandex and polyester-cotton blended fabrics are more and more popular due to their advantages of good wear resistance, good elasticity, no wrinkle, easy washing, and quick drying. More and more people favor it, but conventional disperse dyes have heavy stains on spandex and cotton, and cannot be used for dyeing and printing of polyester-spandex and polyester-cotton blended fabrics. The development of new dyes is an urgent task for dyers. Contents of the invention [0003] The invention provides a ...
