Embodiment 1
[0047] Clean the cotton fabric, rinse and dry it, soak it in the ethanol solution of 5g / L γ-aminopropyltrimethoxysilane for 2min, and dry it at 80℃ for later use; Into 93g of ethanol, ultrasonically oscillate for 15min, stir at 60°C for 2h, add 4g of octadecyltrimethoxysiloxane, continue stirring, slowly add 2mL of ammonia water, and stir for 20h. Add the treated cotton fabric to this solution, soak for 30 minutes, dry at 80°C, and bake at 170°C for 1 minute to obtain a superhydrophobic cotton fabric, measure its static contact angle and spray test score, and simultaneously carry out washing experiments and measure , and the measurement results are shown in Table 1.

[0050] Through the preparation method of this example, hemp fabrics, wool fabrics, polyester fabrics, blended fabrics, etc. are subjected to superhydrophobic treatment, and the superhydrophobic properties a...
Embodiment 2
[0052] Clean the nylon fabric, rinse and dry it, soak it in the acetone solution of 3g / L γ-glycidyl etheroxypropyltrimethoxysilane for 20min, and dry it at 80°C for later use; Add silicon oxide into 90g of acetone, oscillate ultrasonically for 20min, stir at 50°C for 2h, add 6g of hexadecyltriethoxysiloxane, continue stirring, slowly add 2mL of ammonia water, and stir for 20h. Add the treated nylon fabric to this solution, soak it for 30 minutes, dry it in the air, and bake it at 150°C for 5 minutes to obtain a durable superhydrophobic nylon fabric. Measure its static contact angle and spray test score. At the same time, perform a washing experiment and measure it. The results are shown in Table 2.
