Embodiment 1
[0075] 35.0 grams of the original dye shown in the formula (I-1), 2.4 grams of the original dye shown in the formula (I-2), 1.8 grams of the original dye shown in the formula (II-5), and the 10.8 grams of the original dye shown, 70 grams of dispersant MF, and 200 grams of pure water are micronized with a sand mill (for dispersion treatment), and then spray-dried to obtain a yellow-brown disperse dye composition. Based on the original dyes used, the mass fraction of component A represented by formula (I-1) and formula (I-2) is 74.8%, and the mass fraction of component B represented by formula (II-5) and formula (II-7) was 25.2%.
[0076] The dispersion stability of the disperse dye of the present invention at 71°C and 130°C was tested respectively according to GB / T5540 and GB / T5541-2007 by double-layer filter paper filtration method. Among them, the "residue" level at 71°C is level 4, and the "filtration time" level is level A; at 130°C, the "residue" level is still level 4, a...
Embodiment 2~10
[0082] According to the data shown in Table 1, component A, component B, component C, component D, 70 grams of dispersant MF and 200 grams of water are ground and dispersed with a sand mill, and then spray-dried to obtain Disperse dyes.

Embodiment 11
[0087] Get 0.25 gram of the disperse dye (owf=5%) that embodiment 1~10 makes and 0.075 gram of glacial acetic acid (1g / l), be made into 75 milliliters of dye liquors, put into 5.0 gram of polyester superfine fibers and spandex (12% ) blended fabric (commonly known as T+OP fabric, the gray fabric has been pre-set and scoured at 180-195°C) for dyeing, heated from room temperature to 130°C within 60 minutes, kept warm for 45 minutes, and took out the fabric when cooled to below 85°C. Treat the fabric with sodium dithionite and sodium hydroxide at 85°C for 20 minutes, then treat the fabric with an acidic reducing agent (such as hydroxyalkylsulfinate) at a pH of 3.5 to 5.0 at 85°C for 20 minutes, rinse with water, After drying, dry heat setting at 160°C for 30 seconds to obtain a deep colored fabric.
[0088] According to the 2A method specified in AATCC61-2007 color fastness to home and commercial washing, GB / T5713-1997 textile color fastness test to water color fastness (equivale...
