Abstract
A method of making an antimicrobial textile comprising TiO2 nanoparticles is described. The TiO2 nanoparticles are immobilized by first treating a textile with a base, and then contacting with TiO2 nanoparticles in a solution of an alcohol and acid. The textile may be subsequently irradiated with UV light prior to use. The antimicrobial textile shows high effectiveness against the growth and proliferation of microorganisms transmitted within indoor environments.
Claims10
Spinning and weaving method for making an antimicrobial cotton textile, the method comprising:
- spinning cotton fibers to form filaments,
- weaving the filaments to form a cotton textile material;
- treating the cotton textile material with an inorganic base to produce a treated cotton textile material;
- rinsing the treated cotton textile material to produce a rinsed cotton textile;
- depositing a TiO2 coating composition onto the rinsed cotton textile, wherein the TiO2 coating composition contains TiO2 nanoparticles, methanol, and an organic acid, and the depositing forms a coated textile, wherein the TiO2 coating composition fully coats the rinsed cotton textile during the depositing;
- and
- irradiating the coated textile with a UV light to form the antimicrobial cotton textile, wherein the irradiating forms hydrogen bonds between the TiO2 nanoparticles and surfaces of individual fibrils of the cotton textile,
- wherein the TiO2 coating composition contains the TiO2 nanoparticles at a concentration of 10-100 ppm by weight, and the TiO2 nanoparticles are anatase TiO2 nanoparticles having an average particle diameter of less than 21 nm.
