摘要

銀離子本身具有極佳的抗菌性，經奈米化後的銀粒子(Ag)極易釋放出銀離子(Ag(上标 +))而達到頗佳的殺菌效果，而奈米TiO2光觸媒經光催化後則會有良好的抗菌性，因此本實驗利用此兩種複合之奈米抗菌劑改變奈米Ag-TiO2之比例及濃度，並對聚酯織物進行加工，以探討加工物對金黃色葡萄球菌及大腸桿菌之抗菌效果及耐用性的變化。結果發現經由奈米Ag-TiO2複合光觸媒處理後的織物，具有良好的抗菌性，此效果對陽性菌（金黃色葡萄球菌）和陰性菌（大腸桿菌）皆有效，且隨著奈米Ag-TiO2濃度及UV光照時間的增加，其滅菌率也隨之增加，當採奈米Ag-TiO2複合加工劑，不僅可降低奈米銀(Ag)用量，而仍具有良好的抗菌機能，可採奈米TiO2光催化性達到抗菌兼除臭的功能。本實驗並利用耐磨擦及耐水洗測試測其耐用性。

Silver ion autotelic a bactericidal activity, and nanometer silver particles exhibits a strong bactericidal activity. When explored to UV light nanometer titanium dioxide (TiO2) exhibits a strong bactericidal activity. In this study, polyester fabric was treated by nanometer Ag-TiO2 in different concentration, which can be photocatalyzed by UV light.. Polyester is a kind of high physical property fiber. Due to its high crystallinity, polyester metergasis processing was restricted. In this study, we use acryl resin to increase the durable property of polyester. The result of this study shows that potocatalysis treated polyester fabric damage both Gram(-) bacteria and Gram(-) bacteria cells. According to acryl resin the doses, the durable property of treated polyester fabric increased.
