Embodiment 1
[0016] (1) Add 1kg of deionized water, 0.05kg of biomass sugar-based surfactant, 0.15kg of clathrate polyhedral oligomeric silsesquioxane, 0.1kg of nano-zinc oxide particles and 0.001kg of silver nitrate into the reactor, and Stir and mix evenly, add 0.005kg of ammonia water, and react to obtain 1.3006kg of functional reaction liquid.
[0017] (2) Raise the temperature of the functional reaction solution to 50°C, and slowly add 0.0125kg of N-isopropylacrylamide monomer dropwise into it, pre-emulsify and cool to 20°C, then add 0.01kg of azidated Sodium and 0.007kg of propylene glycol block polyether were heated to 60°C for reaction. After about 2 hours, the reaction was completed. The pH value was adjusted to 7 with sodium bicarbonate, and the material was discharged to obtain 1.3301kg of finishing agent.
[0018] The prepared finishing agent is finished on the fabric by roller printing, with one-way moisture conductivity ≥3 grades, water absorption rate (% / s)>100, maximum wet ...
Embodiment 2
[0020] (1) Add 1kg of deionized water, 0.01kg of biomass cardanol sulfonate surfactant, 0.05kg of clathrate polyhedral oligomeric silsesquioxane, 0.02kg of nano-zinc oxide particles and 0.003kg of silver nitrate into the reactor , after high-speed stirring, add 0.002kg of ammonia water, and react to obtain 1.085kg of functional reaction solution.
[0021] (2) Raise the temperature of the functional reaction solution to 55°C, slowly add 0.001kg of N-isopropylacrylamide monomer dropwise into it, after pre-emulsification, cool to 22°C, then add 0.007kg of azidation Sodium and 0.7kg of propylene glycol block polyether were heated to 75°C to react. After 4 hours, the reaction was completed. The pH value was adjusted to 7.5 with ammonium acetate, and the material was discharged to obtain 1.796kg of finishing agent.
