奈米TiO2處理對尼龍織物抗菌性及物性之研究

Antibacterial and Physical Properties of Nanograde TiO2 Particles Treated Nylon Fabrics

摘要


奈米二氧化鈦經光催化後會有極佳的抗菌性,本研究係以不同濃度奈米二氧化鈦對尼龍織物作後加工處理,並探討奈米二氧化鈦經UV光催化後對此尼龍織物的抗菌效果及物性的影響。結果發現經由UV光催化之織物具有良好抗菌效果,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氧化鈦之處理濃度和UV光照時間增加而增加。另,經過二氧化鈦處理後之尼龍織物以UV光照後使強力及柔軟度的損傷較不明顯。因此,尼龍織物經奈米二氧化鈦加工處理並由UV光催化不僅可使織物獲致良好抗菌效果且可提升織物原有良好物性。

並列摘要


The nanograde titanium dioxide (TiO2) is explored by UV light to exhibit a strong bactericidal activity. In this study, nylon fabrics were treated with nanograde titanium dioxide particles, which can be photocatalyzed by UV light in proportion to the irradiation time under a variety of conditions. The effects of antibacterial and physical properties in treated nylon fabrics has been investigated. The results show that in the treated nylon fabrics were less damaged by both Gram(+) bacteria and Gram(-) bacteria cells after TiO2 photocatalytic reaction. The antibacterial effects increases with the TiO2 concentration and UV irradiation time. Another, the strength and softness of Nylon fabrics treated with nanograde titanium dioxide were better after UV irradiation.
