[0028] Composite dyes of different shades are found in Table 1 below:
[0029]
[0030] Table 1
[0031] Wherein the ratio is the mass ratio of acid dyes and reactive dyes.
Embodiment 2
[0033] (1) Dyeing: at room temperature, the Add PPN acidic leveling penetrant and compound dye yellow into the dyeing bath in turn, mix well, adjust the pH value to 5 with pH regulator acetic acid to obtain a dyeing solution, and then immerse the nylon sea-island microfiber leather fabric in the dyeing solution to heat up The rate is 2°C / min, the temperature is raised to 110°C, and kept for 40 minutes, then the temperature is lowered to 80°C, and washed with water to obtain the dyed fabric; the composite dye is dyed at a dyeing depth of 2% (owf), The dosage of PPN acidic leveling penetrant is 2g / L (relative to the dyeing bath).
[0034] (2) Fixing: immerse the above-mentioned dyed fabric in a fixing bath (fixing agent Cibatex PA dosage is 5g / L, pH=4.5), keep at 40°C for 25 minutes, and then wash with water.
[0035] (3) The obtained color samples were tested for rubbing fastness, see Table 2.
[0036] The composite dye red and composite dye blue of Example 1 were dyed and ...
Embodiment 3
[0038] (1) Dyeing: at room temperature, the Add PPN acidic leveling penetrating agent and composite dye Golden Yellow into the dyeing bath in turn, mix well, adjust the pH value to 6 with pH regulator acetic acid to obtain a dyeing solution, and then immerse the nylon sea-island microfiber leather fabric in the dyeing solution to heat up The rate is 1°C / min, the temperature is raised to 105°C, and kept for 60 minutes, then the temperature is lowered to 70°C, and washed with water to obtain the dyed fabric; the composite dye is dyed at a dyeing depth of 0.5% (owf), The dosage of PPN acidic leveling penetrant is 1g / L (relative to the dyeing bath).
[0039] (2) Color fixation: immerse the above-mentioned dyed fabric in a color-fixing bath (the amount of color-fixing agent Cibatex PA is 3g / L, pH=5), keep at 50°C for 20min, and then wash with water.
[0040] (3) The obtained color samples were tested for rubbing fastness, see Table 2.
