Embodiment 1

[0014] A kind of preparation method of the fabric of superhydrophobic function, comprises the steps:

[0015] (1) Add nitric acid to the silicic acid solution at a stirring speed of 600r / min, adjust the pH to 8, and continue stirring for 5h to obtain a silicic acid solution;

[0016] (2) Put the clean fabric in the silicic acid solution prepared in step (1), soak it for 30 minutes, take it out and dry it at 80°C, repeat the soaking and drying steps twice, and combine it on the fiber surface of the fabric Nanoscale silica particles;

[0017] (3) Soak the fabric treated in step (2) in a cetyltrimethoxysilane ethanol solution with a volume fraction of 4% for 10 hours, take it out and dry it at 80°C for 14 hours to obtain a superhydrophobic fabric fabric.

Embodiment 2

[0019] A kind of preparation method of the fabric of superhydrophobic function, comprises the steps:

[0020] (1) At a stirring speed of 400r / min, add nitric acid to the silicic acid solution, adjust the pH to 6, and continue stirring for 4h to obtain a silicic acid solution;

[0021] (2) Put the clean fabric in the silicic acid solution prepared in step (1), soak it for 10 minutes, take it out and dry it at 60°C, repeat the soaking and drying steps 4 times, and combine it on the fiber surface of the fabric Nanoscale silica particles;

[0022] (3) Soak the fabric treated in step (2) in a cetyltrimethoxysilane ethanol solution with a volume fraction of 3% for 12 hours, take it out and dry it at 90°C for 12 hours to obtain a superhydrophobic fabric fabric.

Embodiment 3

[0024] A kind of preparation method of the fabric of superhydrophobic function, comprises the steps:

[0025] (1) At a stirring speed of 200r / min, add nitric acid to the silicic acid solution, adjust the pH to 9, and continue stirring for 5h to obtain a silicic acid solution;

[0026] (2) Put the clean fabric in the silicic acid solution prepared in step (1), soak it for 20 minutes, take it out and dry it at 70°C, repeat the soaking and drying steps 3 times, and combine it on the fiber surface of the fabric Nanoscale silica particles;

[0027] (3) Soak the fabric treated in step (2) in a cetyltrimethoxysilane ethanol solution with a volume fraction of 5% for 8 hours, take it out and dry it at 100°C for 10 hours to obtain a superhydrophobic fabric fabric.

Abstract

The invention discloses a preparation method of a fabric with a super-hydrophobic function. The method comprises the following step that on the basis of combining nano-grade silicon dioxide particles on the surface of the fabric, immersing the fabric into a hexadecyltrimethoxysilane ethanol solution to prepare the fabric with the super-hydrophobic function. The method has a simple process and relatively cost; and the fabric with the super-hydrophobic function is prepared by using environment-friendly materials, so that the fabric has ultraviolet irradiation resistance and water-washing resistance.

Description

technical field [0001] The invention relates to the technical field of functional fabrics, in particular to a method for preparing fabrics with super-hydrophobic function. Background technique [0002] Animals and plants in nature have many strange phenomena, and superhydrophobic surfaces are one of them. The superhydrophobic surfaces of plants and animals are caused by wax-coated rough surface structures. Wax can make the surface have lower surface energy, thereby increasing the contact angle, and rough surface structure can further increase this hydrophobic effect. Because superhydrophobic surfaces have special properties such as waterproof, anti-pollution, and self-cleaning, they have attracted much attention. [0003] In the prior art, the technology of preparing super-hydrophobic surface can be mainly divided into the following categories: etching method on silicon material surface, sol-gel method, chemical vapor deposition method, mechanical stretching method, polyme...
