Embodiment 1
[0027] A method for finishing anti-pollution textiles, comprising the following steps:
[0028] 1) Corona treatment is performed on the cotton cloth: it is carried out under the condition of a mixed gas with a volume ratio of oxygen and nitrogen of 2:8, and the treatment is carried out under the condition of 6kV for 6s.
[0029] 2) Add 1 mol of butyl titanate, 0.4 mol of oxalic acid and 3 mol of sodium dihydrogen phosphate into a mixed solvent composed of 3L of ethanol and 18L of water, seal and heat at 160°C for 36 hours, cool to room temperature, and put the cotton cloth treated in step 1) Immerse in it, adopt the process of two immersion and two dehydration, each immersion for 10 minutes; each dehydration control liquid retention rate is 80%, and dry at 60°C for 3 hours;
[0030] 3) Mix FG-410 water-repellent and oil-repellent treatment agent with water at a concentration of 30g / L. Immerse the cotton cloth treated in step 2) into it, and adopt a two-immersion and two-dehydr...
