摘　　要：采用变温傅里叶变换衰减全反射红外光谱技术(ATR-FTIR),分别研究了山羊绒和绵羊毛的变温红外光谱(包括:变温一维红外光谱和变温二阶导数红外光谱)。研究发现:山羊绒和绵羊毛同时存在着CH_3不对称伸缩振动模式(ν_(asCH_3)),CH_3对称伸缩振动模式(ν_(sCH_3)),CH_2不对称伸缩振动模式(ν_(asCH_2)),CH_2对称伸缩振动模式(ν_(sCH_2)),酰胺Ⅰ带对应的红外吸收模式(ν_(amide-Ⅰ)),酰胺Ⅱ带对应的红外吸收模式(ν_(amide-Ⅱ)),酰胺Ⅲ带对应的红外吸收模式(ν_(amide-Ⅲ))和S=O伸缩振动模式(ν_(S=O))等。研究发现:在293K^393K测定温度范围内,绵羊毛的热稳定性较差,并进一步解释了其热变机理。本项研究拓展了变温红外光谱技术在天然毛纺织材料分析方面的研究范围。By using fourier transform attenuated total reflection infrared spectroscopy（ ATR-FTIR）,the cashmere and wool structures were analyzed respectively by variable temperature infrared spectroscopy（ including variable temperature one-dimensional infrared spectroscopy and variable temperature second derivative infrared spectroscopy）. The research showed that the cashmere and wool simultaneously had CH3 asymmetrical stretch vibration mode（ν（asCH3））,CH3 symmetrical stretching vibration mode（ ν（sCH3））,CH2 asymmetrical stretching vibration mode（ ν（asCH2））,CH2 symmetrical stretching vibration mode（ ν（sCH2））,amideⅠbelt infrared absorption mode（ν（amide-Ⅰ））,amide Ⅱ belt infrared absorption mode（ ν（amide-Ⅱ））,amide Ⅲ belt infrared absorption mode（ν（amide-Ⅲ））,and S = O scissoring vibration mode（ν（S = O））. The research also discovered that the thermal stability of wool was relatively worse in the 293 K ~ 393 K and the thermal mechanism was further explained. The research field of variable temperature infrared spectroscopy in the analysis of natural wool textile materials was expanded.
