纤维定性鉴别的显微红外光谱法

Infrared Microscope Method for Qualitative Identification of Fiber

红外光谱法是鉴别纤维的有效方法之一,难以通过手工拆分且难以用溶解法分离的混合纤维样品、微量的纤维样品等可以使用显微红外光谱法进行定性鉴别,该方法更为直接,是现有纤维定性鉴别方法的有效补充。通过采集单根纤维样品的红外光谱,可以定性鉴别纤维。

Infrared spectroscopy was one of the effective methods to identify fiber.It was more direct to use infrared microscope to identify the mixed fiber samples and micro-samples which were difficult to be disassembled by hand and couldn′t be separated by dissolving method.This method was an effective supplement for the existing qualitative identification methods of fiber.By infrared spectrum measurement of single fiber sample,the fiber could be identified qualitatively.
