| 摘要: | 本研究主要係以過氧化二苯甲醯為化學起始劑，丙烯酸為單體，與聚丙烯不織布行接枝共聚合反應，再以戊二醛為交聯劑將膠原蛋白與根黴菌幾丁聚醣(Rhizochitosan)固定於不織布表面。其中根黴菌幾丁聚醣之去乙醯度約為80%。實驗中主要改變膠原蛋白與根黴菌幾丁聚醣的混合比例，以探討聚丙烯不織布經膠原蛋白及根黴菌幾丁聚醣固定後之固定率及抗菌性。由實驗結果顯示，當聚丙烯不織布接枝率為15%、固定時間18hrs、戊二醛用量25g，膠原蛋白及根黴菌幾丁聚醣比例1:2時具有最佳的固定率。另聚丙烯不織布的抑菌圈效果隨著幾丁聚醣溶液比例的增加而增大，可達12mm。
The study on polypropylene (abbri. PP) nonwoven were grafted with acrylic acid used benzoyl peroxide (BPO) as initiator, and then immobilized with collagen and Rhizochitosan about 80% deacetylation onto modified PP nonwovens. The effect of mixing ratio of collagen/Rhizochitosan on immobilizing ratio and anti-bacterial properties of modified PP nonwoven fabrics had deeply been investigated. From experimental result shown that the P.P.nonwoven grafted with acrylic acid about 15% and ratio of collagen/Rhizochitosan at 1:2, immobilized on the modified PP for 18hrs, could obtain good immobilizing results. On the other hand, the inhibition zone increase with increasing the Rhizochitosanratio. |
