Embodiment 1
[0030] To prepare antimicrobial fibers:
[0031] Step S21, under the condition of nitrogen protection at a temperature of 0°C, mix furfurylamine, triethylamine and chloroform, then add diphenylphosphine chloride, stir for 2h after adding, then heat up to 50°C and continue to stir 3h, after the reaction is completed, wash with deionized water, and remove the solvent by rotary evaporation to obtain solid a; wherein the dosage ratio of furfurylamine, triethylamine and diphenylphosphine chloride is 1:1:1;
[0032] Step S22, under nitrogen protection, mix solid a, glycidyl methacrylate, and deionized water, stir and react at 55° C. for 2 hours, and after the reaction is completed, remove the solvent by rotary evaporation to obtain unsaturated monomers; Wherein, the consumption ratio of solid a and glycidyl methacrylate is 3:1.5;
[0033] Step S23, under nitrogen protection, dissolve azobisisobutyronitrile in chloroform, then add 4-vinylpyridine, unsaturated monomer, 2-(perfluorooc...
Embodiment 2
[0036] Preparation of modified silicone oil:
[0037] Step S11: Mix 4,4' dihydroxydiphenyl disulfide, triethylamine and tetrahydrofuran, add acryloyl chloride dropwise at 0 °C, after the dropwise addition is completed, heat up to 30 °C, stir the reaction for 24h, the reaction ends Then, the solvent was concentrated under reduced pressure to remove the solvent, then dissolved in chloroform, washed with potassium carbonate aqueous solution and deionized water in turn, after washing, dried with anhydrous sodium sulfate, and then the solvent was removed by rotary evaporation to obtain unsaturated phenol monomer; , The molar ratio of 4'dihydroxydiphenyl disulfide, triethylamine and acryloyl chloride is 1:1.01:2;
[0038] Step S12, under the condition of temperature of 70°C, add unsaturated phenol monomer and Custer catalyst to the hydrogen-containing silicone oil, after the addition, the temperature is raised to 100°C, and the reaction is performed for 12 hours. After the reaction is...
Embodiment 3
[0040] To prepare the finish:
[0041] The modified silicone oil obtained in Example 2 was mixed with toluene, then isophorone diisocyanate was added, and the reaction was stirred at 80°C for 3 hours. After the reaction, the solvent was removed, and then the temperature was lowered to 20°C, and saturated hydrogen sulfite was added. The sodium continued to stir for 2 hours until the content of -NCO disappeared to obtain a stock solution; then deionized water and alkylphenol polyoxyethylene ether were added, and then the pH value was adjusted to 5 with acetic acid to obtain a finishing agent. The dosage-mass ratio of modified silicone oil and isophorone diisocyanate is 1:1.6; the dosage-mass ratio of stock solution, deionized water and alkylphenol polyoxyethylene ether is 15:50:9.
