Embodiment 1)
[0021] The cationic dyeable polyester / polyester / nylon / spandex fabric dyeing method of the present embodiment has the following steps:
[0022] ①Immerse the fabric in the first dyeing solution, add glacial acetic acid to adjust the pH of the first dyeing solution to 5.0, then simultaneously refine, dye polyester fibers and dye cationic dyeable polyester fibers at a temperature of 130°C for 30 minutes, and then cool down to Drain below 60°C.
[0023] The first dyeing solution is an aqueous solution containing 2.0g refining emulsifier, 1.0g high-temperature disperse leveling agent, 5.0g sodium sulfate, 0.9g precipitation preventer, 0.08g disperse dye and 0.91g cationic dye per liter; and the disperse dye The total weight of the fabric is 0.08% of the weight of the fabric, and the total weight of the cationic dye is 0.91% of the fabric weight.
[0024] Among them, the refined emulsifier used is SEM-35N refined emulsifier produced by Shanghai Shinshou Chemical Co., Ltd., and its m...
Embodiment 2~ Embodiment 4)
[0034] The dyeing method of each embodiment is basically the same as that of Example 1, and the differences are shown in Table 1.
[0035] Table 1
[0036]
[0037] The fabrics dyed in each example have no blemishes such as colored flowers and stains, and the color fastness to washing (refer to GB / T3921-2008) and color fastness to rubbing (refer to GB / T3920-2008) both reach grade 4-5.
