  • Long-term antibiotic and deodorant textile with mesoporous structure and processing method thereof
    Patent number: 7585331
    Abstract: A long-term antibiotic and deodorant textile with mesoporous structure and processing method thereof are provided. At first, a textile is dipped into an aqueous solution of a surfactant containing nanoparticles. An aqueous solution of a silicon source is prepared and its pH value is adjusted to about 5˜9. Then, the aqueous solution of the surfactant and the aqueous solution of the silicon source are mixed to form a mixture solution. The mixture solution is stirred until silica powder form therein. The textile is taken out and dipped into water and organic solvent separately several times. Finally, the textile is dried to obtain the long-term antibiotic and deodorant textile with mesoporous structure.

  • Method for manufacturing water repellent fabrics by use of metal oxide colloidal
    Publication number: 20070020398
    Abstract: A method for manufacturing water repellent fabrics by use of metal oxide colloidal solutions is disclosed. The fabric is dipped and processed in metal oxide colloidal solution and then is through heat treatment so as to make the fabrics with surface roughness on nanometer scale. Then through water repellent treatment, the fabrics has surface with water contact angle above 150°. The water droplets rolls off on fabrics surface and carry away contaminants so as to achieve self-cleaning effect.
