Abstract

The present invention discloses a kind of fabric containing nano titania mixture and thus self-cleaning function. The titania mixture inside or between the fiber of the fabric contains TiO2 in 0.1-2 wt%. The nano level TiO2 powder is used as photocatalytic material, prepared into reverse emulsion and fixed onto the surface of fiber material via supercritical CO2 processing mode. The fabric containing nano level TiO2 powder is used in bedding, berth cover, curtain, etc. and under the photocatalysis of ultraviolet light in sunlight or lamp light, TiO2 will produce photocatalysis effect to decompose formaldehyde and other harmful gas, purify inside air and provide comfortable health life environment.

Description

1. Technical field [0001] The invention relates to a fabric with light self-cleaning function and a preparation method thereof, more particularly to a fabric containing nano-titanium dioxide mixture with light self-cleaning function and a preparation method thereof. 2. Background technology [0002] Light on TiO 2 The catalysis to promote the chemical reaction was first discovered by Mr. Fujishima, a professor of engineering at the Graduate School of Engineering, University of Tokyo, and it was called the "Fujishima effect" at that time. It has been more than 30 years since its discovery, and countries all over the world have paid attention to the photocatalyst TiO 2 The applied research is also getting more and more in-depth. [0003] The research results found that the photocatalyst reaction is only a surface reaction, and the substances adsorbed (contacted) on the surface react with free radicals, which are only effective for organisms with very small molecules (bacteri...
