| 摘要: | 奈米二氣化鈦經由光催化後會有極佳的抗菌性，本研究以不同濃度奈米二氧化鈦對尼龍織物作後加工處理。探討奈米二氣化鈦光催化後對尼龍織物的抗菌效果及物性的影響，結果發現經由UV光催化之已處理織物有良好抗菌效果，此效果對陽性菌和陰性菌皆有效，且加工後尼龍織物抗菌效果隨二氣化鈦之處理濃度和照射UV光之時問增加而增加，另經過二氣化鈦處理後之尼龍織物之柔軟度會隨著處理濃度的增加而增加，織物強力經奈米二氣化鈦處理後會有損失，但可增加尼龍織物抗UV光老化的效果，對染料之吸收性會變佳，染色時顏色會變深，且染色堅牢度與未加工織物幾乎相同。
When explored to UV light nanometer titanium dioxide (TiO2) exhibits a strong bactericidal activity. In this study, nylon fabric was treated by nanometer titanium dioxide particles, which can be photocatalyzed by UV light. We tested the effect of antibacterial and physical properties of treated nylon fabric. The result of this study shows that photocatalysis treated nylon fabric damage both Gram(-) bacteria and Gram(-) bacteria cells. The reduction rate of bacteria is up to treating concentration and UV irradiation time. According to the Titanium dioxide doses, strength of treated Nylon fabrics decreased, and softness increased. |
