摘　　要：采用傅里叶变换衰减全反射红外光谱技术(ATR-FTIR)、拉曼光谱(Raman)技术和热裂解气相色谱-质谱联用(Py/GC-MS)技术建立了聚烯烃弹性纤维、聚酯类弹性纤维、二烯类弹性纤维和氨纶的鉴别方法。研究发现,通过比较不同纤维的红外特征峰、拉曼特征峰以及裂解特征产物,可以实现弹性纤维的高效、准确检测。Fourier transform infrared spectroscopy, Raman spectroscopy, and pyrolysis gas chromatography-mass spectrometry(Py/GC-MS)were used to identify polyolefin elastic fiber, polyester elastic fiber, diene elastic fiber, and Spandex(polyurethane fiber). The result showed that the efficient and accurate detection of elastic fibers could be achieved by comparing the infrared characteristic peaks,Raman characteristic peaks, and cracked characteristic products of different fibers.
