Embodiment 1)
[0023] The cationic dyeable polyester fabric dyeing and finishing process of this embodiment has the following steps:
[0024] ① Immerse the cationic dyeable polyester fabric in the dye solution, add acid to adjust the pH to 4.5, and then dye it at 120°C for 30 minutes.
[0025] The dye liquor is an aqueous solution containing 1.4g of refined emulsifier, 0.9g of sedimentation preventive agent, 5.0g of sodium sulfate, 2.0g of ultraviolet absorber and 3.2g of cationic dye per liter; and the total weight of cationic dye is 3.2% of the weight of the fabric .
[0026] Among them, the refining emulsifier used is SEM-35N refined emulsifier produced by Shinshou Chemical Co., Ltd., and its main component is polyoxyethylene nonylphenol ether; the precipitation preventive agent is produced by Jiangsu Dewang Chemical Industry Co., Ltd. Preventive agent HT-77, its main component is fatty alcohol polyoxyethylene ether.
[0027] The ultraviolet absorber used is Hipom UV-330 produced by Suz...
Embodiment 2~ Embodiment 5)
[0037] The dyeing and finishing process of each embodiment is basically the same as that of Example 1, and the differences are shown in Table 1.
[0038] Table 1
[0039]
[0040] Among them, the contact cooling coefficient q max With reference to GB / T 35263-2017 "Testing and Evaluation of Textile Cooling Feeling at Instant Contact", the test conditions are: temperature 20±0.2°C, humidity 65±2%, △T=15°C. The evaluation index is ≥0.15J / cm 2 ·s.
