摘要

本研究係以奈米銀纖維經後處理方式對聚酯織物進行加工，首先將不同長徑比之奈米銀纖維與水性PU樹酯摻合均勻分散後，對聚酯織物進行加工處理，製得具有抗菌消臭及靜電消散之多機能性產品。藉由改變奈米銀纖維長徑比及添加量探討其抗菌效果及抗靜電性，並以電子顯微鏡觀察其外觀變化。由研究發現長徑比越小者其滅菌率較佳，但導電性越低，靜電消散之能力也越弱。奈米銀濃度越高電阻係數越低，亦即抗靜電效果越佳，且隨著水洗次數增加，聚酯加工布表面上之銀纖維越明顯，在經20次耐水洗測試後電阻值最高為10^2Ω/▓，亦即仍保有良好之靜電消散能力。

In this study, the multifunctional polyester fabrics treated with nanosilver fiber to be processed. The different aspect ratio of nanosilver fibers and water-based PU resin were uniformly blended into solution. The effect concentration of nanosilver pick up ratio of fabrics on antibacterial deodorizing and static dissipation were researched. The surfacial phenomena of treated fabrics were observed by scanning electron microscope. From experimental results found that the smaller aspect ratio was the better antibacterial ability, but the lower conductive properties. So that will decrease the antistatic efficiency. The surfacial electric resistance of finished fabric decreased with the increasing of concentration of nanosilver solution, that mean the antistatic function of fabrics were improved. The electric resistance of samples after washing were decreased. That still maintain the better ability of static dissipation for the treated fabrics in many washing tests.
