PURPOSE: A dye mixture of a fiber-reactive azo dye is provided, which has excellent washoff property to an unfixed part of fiber, a direct property, a light fastness, and a wet fastness. The dye mixture is used for dyeing a hydroxyl- and/or carboxamido-containing fiber material. CONSTITUTION: The dye mixture comprises at least one dye represented by the formula 101, 0-10wt% of at least one monoazo dye represented by the formula 15 or 16, and at least one dye represented by the formulas 103a, 103b, and etc, wherein the dyes represented by the formulas 101, 103a, 103b, and etc comprises at least one fiber-reactive group of -SO2-Z or -Z2. And the dye mixture is produced by mixing the dyes represented by the formulas 101, 15, 16, 103a, 103b, and etc mechanically in the solid or water solution state in the specified ratio. In the formulas, D1-D5 are independently the formula 1, wherein R1 and R2 are independently hydrogen, a C1-C4 alkyl, a C1-C4 alkoxy, and etc, X1 is hydrogen or -SO2-Z, wherein Z is -CH=CH2, -CH2CH2Z1, etc, R* and R** are independently hydrogen, a C1-C4 alkyl, or -CH2-SO3M, R31 is hydrogen, acetyl, carbamoyl, and etc, R32 is hydrogen or -CH2-SO3M, and M is an equivalent material of hydrogen, an alkali metal, or an alkali earth metal. |
