摘要： 长期以来,纤维材料需要切成细微粉末才能测得红外光谱。1981年Teramae和Tana-ka[1]采用傅里叶变换红外光声光谱(FTIR-PAS)获得棉花及尼龙纤维的红外光声光谱图,它与常规KBr制样得到的红外光谱图一致。该法不需要复杂制样,具有快速简便、无损样品的优点,所得的光谱图便于计算。

Abstract: Forrier transform infrared photoacoustic spectroscopy for untreated and alkali treateddegummed ramie fiber were recorded.It indicated that when the alkali concentrationincreased, the intensity of band near 1430cm-1 assigned to crystalline region of the fibergraually declined, but that for the band near 898cm-1 assigned to uncrystalline regiongradually inclined.When the alkali concentration was more than 9.0%(w/w), the area of 898cm-1 band assigned to CH stretching vibration was near constant.Meanwhile, the alkalitreating temperature (20～80℃) and time (30～120min) appeared almost no influence.

Key words: Fourier transform infrared photoacoustic spectroscopy, degummed ramie, alkali treatment
