Problems solved by technology

[0004] At present, most superhydrophobic textiles are prepared by physical coating with low surface energy substances such as fluorine-containing monomers and siloxanes. The preparation cost is high, and the interaction between hydrophobic finishing agents and fiber substrates is weak. It will gradually lose its superhydrophobicity when subjected to mechanical friction or chemical corrosion, thereby shortening its service life

preparation example Construction

[0031] The specific operation steps of the preparation method of a kind of anti-ultraviolet superhydrophobic cotton cloth provided by the invention are as follows:

[0032] Step 1: Wash the cotton cloth three times, wash with distilled water and then with absolute ethanol solution for each washing, so that the dust and organic matter and other impurities on the surface of the cotton cloth are rinsed, and then completely dry the cotton cloth for the first time, and after the first complete drying The cotton cloth is soaked in the absolute ethanol solution of nano-titanium dioxide with a mass concentration of 1 to 6wt%. The particle size of the titanium dioxide particles in the anhydrous ethanol solution of nano-titanium dioxide is 20nm. The container mouth is sealed and placed in an ultrasonic cleaner to disperse , disperse so that the titanium dioxide particles are evenly distributed on the surface of the cotton cloth, the temperature during dispersion is 20-50°C, and the dispe...

Abstract

The invention discloses a preparation method for uvioresistant super-hydrophobic cotton. The detailed preparation steps are as follows: 1, washing the cotton and drying the cotton fully for the firsttime, soaking the fully-dried cotton in absolute ethyl alcohol solution of nanometer titanium dioxide, sealing the container mouth, placing the container in an ultrasonic cleaner for dispersion, taking out the cotton, washing the cotton with distilled water, and drying the cotton fully for the second time; 2, soaking the fully dried cotton in absolute ethyl alcohol solution of lauric acid and taking the cotton out after 8-24 h, and then the uvioresistant super-hydrophobic cotton is obtained after high temperature drying; the preparation method for the uvioresistant super-hydrophobic cotton issimple and low in cost, and has superior anti-ultraviolet light, self-cleaning and superhydrophobic performances, so the preparation method can be promoted for industrial production.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and in particular relates to a method for preparing an anti-ultraviolet superhydrophobic cotton cloth. Background technique [0002] In recent years, cotton fabrics have been used in many fields (medicine, military, clothing, and wearable electronic products, etc.) due to their unique advantages, such as comfort, softness, and breathability. However, the original cotton fiber fabric also has some disadvantages, such as low mechanical strength, easy to wrinkle, easy to dirty, flammability, and weak UV blocking ability, etc., which limit its wide range of uses. With the continuous improvement of the functionality and diversification of textiles, a textile material with superhydrophobic properties has attracted great attention from researchers at home and abroad because of its attractive prospects. Such as superhydrophobicity, anti-pollution and self-cleaning properties, UV protection,...
