本研究係探討如何利用顯微紅外光譜（Micro FT-IR）、纖維橫切面形狀及直徑測量之系統分析方法，達到個化纖維的目的。實驗總共蒐集109種纖維：天然纖維17種，化學纖維92種；而研究重點在於化學纖維之鑑析。對於化學纖維之分類共分為三大類：聚酯纖維、聚醯胺纖維及聚丙烯纖維。以顯微紅外光譜法而言，可達到各類纖維分類之效果，而且樣品製備簡單、快速。本研究所採行之前處理方法，僅需將待析的樣品置於載玻片上，再以滾輪磨平即可進行紅外光譜分析。顯微紅外光譜雖可達到分類之目的，但在纖維之個化上卻未能達到理想的效果。尤其在聚酯纖維及聚丙烯纖維同分子結構之鑑析，僅能得到相同的紅外光譜；不論是官能基的位置、分佈或吸收強度皆相似，無法有效個化纖維。因此加入橫切面形狀及直徑測量二因子來加強個化能力，實際執行上，先觀察橫切面之形狀並以其分類，不同形狀之纖維當然為不同之纖維；形狀相同者，再比較其直徑之差異，如此，則可將相同分子結構之纖維詳細分類，可有效達到準個化(超細分類)纖維之目的。

Microscopic FT-IR, fiber diameter and cross-sectional shape were used to individualize single fiber in this study. 109 fibers were analyzed including: 17 natural fibers and 92 manufactured fibers. FT-IR Microspectroscopy analysis requires minimal sample preparation compared to conventional infrared analysis. Excellent infrared spectra were obtained from flattened single fiber before analysis. Infrared spectra can only show their generic group. For fiber individualization purpose, this research also measured fiber diameter and fiber cross-sectional shape. By using fiber diameter, cross-sectional shape, infrared spectra, we successfully separated 109 fibers into different groups.
