preparation example Construction

[0034] The invention provides a kind of preparation method of superhydrophobic polyester fabric, comprises the following steps:

[0035] Step a. prepare the reaction solution, by volume percentage, the reaction solution includes 1-8% hexadecyltrimethoxysilane, 1-16% tetraethyl orthosilicate, 5-15% with a mass fraction of 25 -28% ammonia water and 33-68% absolute ethanol to prepare the reaction solution;

[0036] Step b. adding the reaction solution into a bubble stirring device, soaking the polyester fabric to be treated in the reaction solution for bubble stirring, and obtaining a super-hydrophobic polyester fabric after the stirring is completed.

[0037] Above-mentioned, the step of preparing superhydrophobic polyester fabric is specifically as follows:

[0038] Mix hexadecyltrimethoxysilane, tetraethyl orthosilicate and absolute ethanol, and add ammonia water dropwise while stirring to prepare a reaction solution. Under the catalysis of ammonia water, hexadecyltrimethoxy...

Embodiment 1

[0082] Wash the polyester fabric to be treated, and dry it at 60°C for subsequent use;

[0083] In terms of volume percentage, 5% cetyltrimethoxysilane, 4% tetraethylorthosilicate, 10% ammonia water (25% by mass), and 81% absolute ethanol were prepared as a reaction solution;

[0084]Add the reaction solution into the bubble stirring device, soak the polyester fabric to be treated in the reaction solution and stir the bubbles for 2 hours, take out the polyester fabric after stirring, rinse the residual liquid on the surface with absolute ethanol, and dry it at 130°C for 1 hour to obtain a super Hydrophobic polyester fabric.

Embodiment 2

[0086] The reaction solution in Example 1 is prepared as follows: by volume percentage, 5% of hexadecyltrimethoxysilane, 2% of tetraethyl orthosilicate, 10% of ammonia water (mass fraction is 25%) , 83% absolute ethanol to prepare the reaction solution. Other steps are identical with embodiment 1.

Abstract

The invention provides a method for preparing a superhydrophobic polyester fabric and a bubble stirring device. The preparation method comprises: by volume percentage, 1-8% hexadecyltrimethoxysilane, 1-16% tetraethyl orthosilicate, 5-15% ammonia water with a mass fraction of 25-28% and 33-68% absolute ethanol to prepare a reaction solution, add the reaction solution into a bubble stirring device, soak the polyester fabric to be treated in the reaction solution for bubble stirring, and obtain a superhydrophobic polyester fabric after the stirring is completed. The superhydrophobic polyester fabric prepared by the above preparation method has lipophilic and hydrophobic properties and good hydrophobic uniformity. Its surface static water contact angle can reach more than 140°, the oil-water separation efficiency can reach more than 95%, and the oil flux can reach 32352.6L / (m 2 h). The preparation method has the characteristics of high production efficiency and simple process.

Description

technical field [0001] The invention relates to the technical field of fabric processing, in particular to a method for preparing a superhydrophobic polyester fabric and a bubble stirring device. Background technique [0002] Superhydrophobic fabrics refer to fabrics whose contact angle with static water is greater than 150°, and are gradually favored by people because of their properties such as snow resistance, pollution resistance, oxidation resistance, and current conduction prevention. In the prior art, the micro-nano composite rough structure and low surface energy are the key factors for the formation of super-hydrophobic surfaces. As the most widely used material in the superhydrophobic field, polyester fiber has been vigorously developed in recent years. Polyester fiber itself has a micron-scale rough structure, which provides favorable conditions for the preparation of superhydrophobic fabrics. Fluoropolymers not only have good hydrophobic and oleophobic properti...
