In this study, cotton fabrics were coated with TiO₂ nanoparticles using 3-mercaptopropyltrimethoxysilane(3-MPTMS), which is highly reactive to cotton fabrics, as a medium, and the characteristics, antimicrobial properties, and photodegradation properties of the fibers were measured. The manufacturing process is as follows. (1) 3-MPTMS was added to isopropanol, and TiO₂ colloid was added to the mixture to prepare a solution. (2) Cellulose fibers were immersed in the prepared 3-MPTMS/TiO₂ solution, stirred for 90 minutes at 45℃ in a constant temperature water bath, and dried thereafter. In order to identify the morphology of the cellulose fibers coated with TiO₂ nanoparticles, the surface was observed with a scanning electron microscope(SEM), and SEM-EDS was measured to identify the adhesion of TiO₂ nanoparticles. The SEM images showed TiO₂ nanoparticle and 3-MPTMS coated layers on the fibers and it was identified that TiO₂ nanoparticles were attached to the cellulose fibers. The antimicrobial activity of 3-MPTMS/TiO₂-treated cotton fabrics was measured using a bacterial reduction method. 3-MPTMS/TiO₂ cellulose fibers which was irradiated by ultra violet light, showed antimicrobial activity against Escherichia coli(ATCC 43895) and Staphylococcus aureus(ATCCBAA-1707) unlike unirradiated fibers. The cellulose fibers were stained with methylene blue and the photodegradation performance of the stained fabrics was analyzed. The stained fabrics showed high degradation performance with photolytic reactions of TiO₂ nanoparticles.
