Embodiment 1
[0034] With the disperse blue dye (component A) 40g shown in I-1, the disperse violet dye (component B) 10g shown in II-2, the disperse yellow dye (component C) 10g shown in III-1, IV Disperse yellow dye (component D) 10g shown in -3, 30g of dispersant 85A (sodium lignosulfonate) is added in 200g water, after continuous grinding, after spray drying, the finished product packaging obtains the disperse black dye composition for superfine fiber .
Embodiment 2-15 and comparative example 1-3
[0036] According to the ratio shown in Table 1, other operations are as in Example 1.

Embodiment 16
[0041] Get the disperse dye that above-mentioned embodiment 1-15 and comparative example 1-4 make carry out printing and dyeing property test, test method is as follows:
[0042] Each get the disperse dye that 0.5g embodiment 1-15 and comparative example 1-4 make, make the disperse dye suspension that concentration is 1.0g / L respectively with water, get 20mL disperse dye suspension and mix with 80mL water, wash with acetic acid Adjust the pH to 4.5-5.0, then raise the temperature to 60°C, add 2g of polyester microfibers for dyeing, raise the temperature to 130°C within 35 minutes, keep the temperature for 30 minutes, and take samples when cooled to 80°C. Observe the shade of the cloth sample and measure its color fastness using GB / T3921, GB / T3920-1997, GB / T5718-1997, and measure the dye uptake rate by GB / T9337-2009. The measurement results are shown in Table 2
