Embodiment 1
[0025] A method for preparing superhydrophobic-antibacterial-ultraviolet protective polyester fiber cloth by dipping deposition method, is characterized in that, comprises the steps:
[0026] (1) Surface chemical graft polymerization modification of polyester fiber cloth:
[0027] Introduce nitrogen gas into the N-methylolacrylamide aqueous solution of the monomer, raise the temperature to 80-85°C, add the swelled polyester fiber cloth and the benzene solution of benzoyl peroxide as the initiator, and stir and reflux grafting reaction for 2 hours, Take it out, wash it twice with distilled water at 90-95°C, extract it with methanol for 3 hours, and dry it in an oven at 110-120°C to constant weight to obtain a polyester fiber cloth modified by surface graft polymerization;
[0028] (2) Preparation of chitosan-nanocomposite antibacterial agent-polyester fiber cloth:
[0029] Add hydrochloric acid solution to chitosan powder, fully dissolve, add sodium hydroxide solution dropwise...
