Paragraph 0108-0110; 0116, (2017/08/28)
Disclosed are a disperse dye composition, and a preparation method and application thereof. The disperse dye composition comprises a component A composed of one or more of compounds shown as a formula (1) (please see the specifications for the formula), a component B composed of one or more of compounds shown as a formula (2) (please see the specifications for the formula), forbidden aromatic amine compounds, chlorinated phenols, chlorobenzene and chlorotoluene, optional auxiliaries, and other unavoidable impurities. The total content of the forbidden aromatic amine compounds is 10 ppm or below, the respective content of the various chlorinated phenols is 0.5 ppm or below, and the total content of the chlorobenzene and chlorotoluene is 1 ppm or below. The various environment protection indexes of the disperse dye composition meet the requirements of Oeko-Tex Standard 100(2016). In addition, after fabric is dyed through the disperse dye composition, the dyed fabric meets the baby level requirements of Oeko-Tex Standard 100(2016).
