Zusammenfassung:A reactive dye compound and preparation method and application for printing and dyeing of cellulosic fibers, polyamide fibers and fabrics thereof. Formula (I) is the dye compound structure where D1 and D2 are each independently the group of the following formula (a) or (b) or (c), and D1 and D2 are not simultaneously selected from the following formula (a). R1, R2, R4, R5, R7 and R8 are each independently H, linear or branched C1˜C4 alkyl, C1˜C4 alkoxy or sulfo; m=0-3. Each R3 is independently selected from amino, sulfo, ureido, C1˜C4 alkyl, C1˜C4 alkanoylamino or C1˜C4 alkoxy, n=0-3, and each R6 is independently selected from hydroxyl, amino and sulfo. X1, X2 and X3 are each independently H, C1˜C4 alkyl, C1˜C4 alkoxy, -SO2Y1, -NHCO(CH2)pSO2Y2 or -CONH(CH2)qSO2Y3, and at least one of D1 and D2 contains a fiber-reactive group. Y1˜Y3 are each independently -CH═CH2, -C2H4OSO3H or -CH2CH2Cl, p=1-3, and q=1-3.
