本論文主要是探討以混成高分子膜塗佈於不織布方式，將具有良好光催化與抗菌功能氧化鋅無機光觸媒形成混成膜塗佈在不織布上。接著針對塗佈薄膜進行製程改變，如各種光觸媒溶液、不同之濃度，並對於經過不同製程改善處理之不織布，以場發射式電子顯微鏡(FESEM)觀察纖維上光觸媒分布情形及混成膜表面形態。在光觸媒活性方面分析，採用以仿太陽光之鹵素燈作為光源，進行亞甲基藍染料光降解速率測定，並以大腸桿菌與金色葡萄球菌為基準，利用混成膜塗佈之不織布纖維進行抗菌能力測試。另外一方面，也將光觸媒粉體與高分子透過高分子加工方式形成抗菌纖維。同樣地測定抗菌纖維是否有光催化特性與抗菌能力。
實驗結果顯示，此方法所製備出重量比為40 wt% 薄膜不織布，光觸媒能成功附著上纖維上，本實驗的不織布披覆上混成膜，有極佳的光催化效率，在鹵素燈照射30分鐘後，對於100毫升的亞甲基藍(5 ppm)降解率可達90%以上。然而，在抗菌試驗中，比例為40 wt%光觸媒之混成膜不織布，於20W LED光源中，讓不織布與菌液充分震盪均勻，經過2小時後，混成膜之不織布達到無殘存的抗菌能力。在抗菌纖維方面，以重量比為5%的複合粉體所製備之抗菌纖維，經由日本抗菌標準法進行檢測，結果得到抗菌纖維對於金色葡萄球菌以及大腸桿菌能達99.9%之殺菌力。

This study was to investigate the hybrid coatings with photocatalytic and antibacterial functions on the non-woven fabric. The hybrid coatings contained the polymer of nylon and the inorganic powder of zinc oxide. The effects of the solid loading of inorganic powder and the the different inorganic powders on the photocatalysis of hybrid-coated non-woven fabric were studied with the morphological and optical analyses, photodegradation of methylene blue, and the antibacterial ability.
Experimental results show that three types of non-woven fabrics, e.g. 40 wt% of zinc oxide in 60% nylon to form the hybrid film on PET non-woven fabrics. The non-woven coated hybrid film in this work performed excellent photocatalytic efficiency. Under a halogen lamp, 100 ml methylene blue of 5 ppm could be degraded by 90% in 30 minutes. Meanwhile, the 40 wt% photocatalyst coated non-woven shocked in bacteria liquid under the light of 20W LED for 2 hours shows little bacteria survival under the oxidation of non-woven fabrics with hybrid film.
The melt-drawn hybrid fibers with 5% inorganic powder had also been performed. For antibateria test via the Japanese standard method, this hybrid fiber shows the bactericidal activity up to 99.9% for and Escherichia coli and Staphylococcus aureus.
