Examples
Embodiment 1
[0022] (1) Immerse the textile in a sodium periodate solution with a molar concentration of 2 mmol / L, react in the dark at 50°C for 45 minutes, then wash with deionized water three times, dry at 80°C, and set aside;
[0023] (2) Immerse 10 g of the textiles treated in step (1) into 100 mL of urea solution with a mass-volume concentration of 6 g / L, then react in a water bath at 30°C for 8 hours, filter, wash with deionized water for 3 times, and heat at 80°C dry, ready for use;
[0024] (3) adding the textiles processed through step (2) into the solution containing cobalt tetracarboxyphthalocyanine and leveling agent Pingping O, the mass-volume concentration of cobalt tetracarboxyphthalocyanine is 0.4g / L, and Pingping adding O The mass-volume concentration is 1g / L, the bath ratio is 1:50, the pH value is adjusted to 4, treated at 90°C for 90min, washed 3 times with water, and dried.
