Abstract

The invention relates to a preparation method of self-cleaning fabrics, and belongs to the technical field of textile materials. According to the preparation method, titanium is used as a target material, a titanium dioxide film is sputtered on the surface of the base fabric as a substrate, polyvinylidene fluoride is used as a raw material, a nanofiber membrane is prepared by electrostatic spinning, and the nanofiber membrane is compounded on the surface of the substrate through hot pressing, so that the self-cleaning fabrics are prepared. According to a magnetron sputtering method, nano TiO2particles are deposited on the surfaces of the fabrics by utilizing an electromagnetic technique in a vacuum environment so as to form a nano TiO2 film, and the photocatalytic self-cleaning performance is given to the fabrics; anatase types generally react with H2O or OH- ions adsorbed to the surfaces so as to form hydroxyl radical with a strong oxidizing property; and electrons react with oxygenmolecules adsorbed to the surfaces, the oxygen molecules can participate in the reduction reaction and are used as the other source of surface hydroxyl groups, and all kinds of organic matter can be oxidized into micromolecules such as CO2 and H2O, so that the purpose of keeping the materials clean is achieved.

Description

technical field [0001] The invention relates to a preparation method of a self-cleaning fabric, which belongs to the technical field of textile materials. Background technique [0002] Self-cleaning fabrics can clean stains through the fabric itself, and its application and development can effectively reduce the use of traditional cleaners and disinfectants. At the same time, the self-cleaning fabric has a certain disinfection and sterilization effect, so it protects human health to a certain extent. At present, self-cleaning fabrics have been partially used in household products, medicine, construction and other fields. [0003] Self-cleaning fabrics refer to materials that have the ability to superhydrophobic or photocatalytically degrade pollutants after post-processing. The development of this material can reduce the number of washings of clothes or realize no-washing of clothes, thereby reducing the use of detergent, and finally achieving the goals of energy saving, w...
