Embodiment 1
[0028] The composite dyes of different shades are shown in Table 1 below:
[0029]
[0030] Table 1
[0031] The ratio is the mass ratio of acid dye and reactive dye.
Embodiment 2
[0033] (1) Dyeing: under normal temperature, PPN acid level dyeing penetrant and composite dye yellow are added to the dyeing bath in sequence, and mixed evenly. Adjust the pH to 5 with the pH adjuster acetic acid to obtain the dye solution, and then immerse the nylon sea-island microfiber leather fabric in the dye solution to heat up The rate is 2°C / min, the temperature is increased to 110°C, kept for 40 minutes, and then the temperature is lowered to 80°C, and the dyed fabric is obtained. The composite dye is dyed with 2% (owf) deep dyeing. The dosage of PPN acid leveling penetrant is 2g / L (relative to the dye bath).
[0034] (2) Fixing: Immerse the dyed fabric in the fixing bath (the amount of fixing agent Cibatex PA is 5g / L, pH=4.5), keep it at 40℃ for 25min, and then wash it with water.
[0035] (3) The resulting 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 fixed according to the c...
Embodiment 3
[0038] (1) Dyeing: under normal temperature, PPN acid level dyeing penetrant and composite dye golden color are added to the dyeing bath in turn, mix well, adjust the pH value to 6 with the pH adjuster acetic acid to obtain the dye liquor, and then immerse the nylon sea-island microfiber leather fabric in the dye liquor to heat up The rate is 1℃ / min, the temperature is increased to 105℃, kept for 60min, and then the temperature is lowered to 70℃, and the dyed fabric is obtained. The composite dye is dyed with 0.5% (owf) deep dyeing. The dosage of PPN acid leveling penetrant is 1g / L (relative to the dye bath).
[0039] (2) Fixing: Immerse the dyed fabric in the fixing bath (the amount of fixing agent Cibatex PA is 3g / L, pH=5), keep it at 50℃ for 20min, and then wash it with water.
[0040] (3) The resulting color samples were tested for rubbing fastness, see Table 2.
[0041] The composite dye scarlet, composite dye violet, and composite dye Turquoise blue of Example 1 were respecti...
