Abstract

A process of preparing coatings of fabrics which could remove noxious substances in air. It comprises:1) pretreat fabrics;2) resisting ageing;3) the primary coating process, to obtain fabrics with active carbon coatings;4) the secondary coating process. The secondary coating composition comprises: 5úÑí½25úÑ composite emulsion of nanometer-grade TiO2/ transition metal ion, 2úÑí½5úÑ adhesive of polyacrylic acid, 1úÑí½3úÑ thickening agent of polyacrylic acid. The secondary coating composition is heated for 2-5min at 80í½100degree C, then heated at 150í½180degree C for 1-3 min. then, a fabric with a coating of nanometer-grade TiO2/ transition metal ion. The invention is suitable for fabrics of various fibers. The composite nanometer-grade TiO2 fabric could effectively get rid of pollutants indoors.

Description

technical field [0001] The technical solution claimed in the present invention relates to a preparation method for treating fabric with an inorganic compound coating, specifically a preparation method for treating fabric with a nano titanium dioxide dispersion emulsion coating. Background technique [0002] At present, the application of nanomaterials in the textile industry is mainly manifested in two aspects: first, mixing nanomaterials with polymer spinning solution to make nanocomposite fibers; second, making nanomaterials into dispersion emulsion, and then Anti-ultraviolet finishing, anti-static finishing, anti-bacterial and deodorant finishing or anti-wrinkle finishing are carried out on the fabric by padding method or coating method to obtain special functions such as anti-bacterial and deodorant, anti-ultraviolet, anti-static, and non-ironing properties. Nanocomposite fabrics. [0003] As far as the nanocomposite fabric technology utilizing the coating method to pre...
