  The present invention provides an orange active dye and the preparation method thereof. The coupling constituent is sodium 2,4-diamino-benzene sulfonate, and the diazo constituent is 2-naphthylamine-disulfonic acid and β-hydroxyethylsulfurylsulfate aniline. The product is obtained by coupling twice, filtering, drying and packing. The active orange dye has an excellent solubility, and has a rate of exhaustion of 96% in dyeing. It is apparently superior to acid dyes, and greatly reduces the difficulty of environmental treatment.
