Embodiment 1

[0034] Component A of 40 grams of formula (I-1), component B of 60 grams of formula (II-1), and sodium lignosulfonate of 195 grams were mixed with water, ground and dispersed with a grinder, and spray-dried. The finished product is obtained, and the dyestuff is capable of imparting a uniform orange shade to the fabric with good fastness properties.

[0035]

Embodiment 2～10

[0037] According to the data shown in Table 1, Component A, Component B, 195 grams of additives, and water were blended, then ground and dispersed with a grinder, and then spray-dried to obtain a finished product.

[0038] Table 1

[0039]

Embodiment 11

[0041] Take 0.5 grams of the disperse dyes prepared in Examples 1 to 10 and disperse them in 500 milliliters of water, absorb 20 milliliters and mix them with 60 milliliters of water, adjust the pH of the dyeing bath to 5 with acetic acid, heat up to 70°C and put 2 grams of poly The ester fiber is dyed, the temperature is raised from 70°C to 130°C within 30 minutes, the temperature is kept for 30 minutes, and the sampling starts when it is cooled to 90°C. Observe the color and light of the sample cloth, and use the national standard GB / T3921-1997, GB / T3920-1997, GB / T5718-1997, GB / T8427-1998 to test its fastness to washing, rubbing, perspiration and sunlight respectively. The results are shown in Table 2.

[0042] Table 2

[0043] Example

[0044] The test results show that the disperse orange dye composition provided by the invention has excellent fastness properties, and the compounding effect is remarkable.

Abstract

The invention discloses a dispersed orange dye composition, which is composed of 1-99% one or several dye A with formula (I) and 1-99% one or several dye B with formula (II), wherein the composition can be microparticled into liquid pattern, cream pattern or powder and particle pattern, which makes polyester fiber material display yellow to orange to red.

Description

(1) Technical field [0001] The invention relates to a disperse orange dye composition and a disperse dye, in particular to a disperse dye composition and a disperse dye for printing and dyeing polyester and its blended fabrics. (2) Background technology [0002] With the rapid development of new polyester fibers in recent years and the improvement of people's requirements for textiles, correspondingly, higher requirements have been put forward for the dyeing performance and environmental protection performance of the dye itself. That is to say, dyes are required to have good thermal migration resistance and excellent dyeing fastness. [0003] Azo dyes occupy the largest market share due to their relatively simple synthesis and easy realization of large-scale industrial production. The blending application of dyes is very common. For example, patents EP0491386, JP10251534, and JP08100132 are all applications of dye blending, with the purpose of improving the printing and dye...
