Embodiment 1
[0026] Prepare the aqueous solution of finishing solution A, wherein the polyepichlorohydrin dimethylamine derivative is 12g / L, the pH of the solution is adjusted to 10~12 with sodium hydroxide, and the cotton yarn card (20 s ×16 s , 128×60) in the finishing solution A, dipped twice and rolled twice, with a liquid-carrying rate of 70%, and dried at 80°C;
[0027] Add 5% triammonium citrate aqueous solution dropwise to the mixed system of 2% water glass and 1% cetyltrimethoxysiloxane in 50mL of mass percentage concentration until the pH of the solution The value reached 10.7, and then stirred for 30 minutes to obtain finishing solution B; the cotton yarn card that had been treated above was dipped and rolled twice in the obtained finishing solution B, the liquid-carrying rate was 70%, pre-baked at 80°C for 3 minutes, and baked at 160°C Bake for 3 minutes to obtain a cotton fabric with superhydrophobic function.
Embodiment 2
[0029] Prepare the aqueous solution of finishing solution A, wherein 2,4-dichloro-6-(2-pyridoethylamino)-s-triazine polyamide polymer is used as a cationic modifier, and the amount is 5g / L, and the Sodium adjusted the pH of the solution to 9.5, and the linen (14 s ×14 s , 54×52) soaked at 60°C for 30 minutes, then washed with water until neutral, and dried at 80°C;
[0030] To the mixed system of 2% water glass and 0.5% cetyltrimethylammonium chloride in the mass percent concentration of 50mL, add ammonium sulfate aqueous solution dropwise until the pH value of the solution reaches 10.7, after that Stir for 30 minutes to obtain finishing solution B; at 60°C, immerse the cationic-modified linen fabric in finishing solution B for 60 minutes, the bath ratio is 1:40, pre-bake at 80°C for 3 minutes, wash with water, and bake at 170°C for 2 minutes Minutes, get antibacterial linen fabric.
Embodiment 3
[0032] Prepare the finishing solution A aqueous solution, wherein with glycidyltrimethylammonium chloride as cationic modifier, consumption is 5g / L, adjust pH to about pH 7 with sulfuric acid, cotton gauze card (20 s ×16 s , 128×60) at 60°C for 30 minutes, with a bath ratio of 1:10, mixed thoroughly and evenly, after dipping, take it out and dry it in an oven at 50°C, and bake at 90°C for 30 minutes. Then take out to wash and dry.
[0033] Add ammonium chloride aqueous solution dropwise to the mixed system of 50mL of water glass with a mass percentage concentration of 2% and flame retardant FR-PN with a mass percentage concentration of 2%, until the pH value of the solution reaches 10.7, and then stir for 30 minutes , to obtain finishing solution B; at 60°C, the cationic modified cotton yarn was dipped and rolled twice in finishing solution B, with a liquid retention rate of 75%, prebaked at 80°C for 3 minutes, and baked at 160°C for 3 minutes to obtain Flammable cotton fabr...
