摘　　要：探讨麻纤维的热稳定性。研究了不同温度下亚麻、黄麻及苎麻纤维的二阶导数红外光谱。试验发现:在3 000cm^(-1)～2 800cm^(-1)、1 450cm^(-1)～1 400cm^(-1)、1 350cm^(-1)～1 300cm^(-1)和1 100cm^(-1)～1 000cm^(-1)等四个频率区间内,亚麻、黄麻及苎麻纤维主要存在着—CH伸缩振动模式、—OH变形振动模式和C—O伸缩振动模式等三种红外吸收模式;随着温度的升高,黄麻纤维的主要官能团变化显著。认为:与亚麻和苎麻纤维相比,黄麻纤维的热稳定性较差。The thermal stability of hemp fibers was discussed.The second derivative infrared spectroscopy of flax,jute and ramie fibers at different temperatures were studied.The results showed that flax,jute and ramie fiber mainly existed in three kinds of infrared absorption modes in the four frequency intervals.The four frequency intervals were 3 000 cm-1~2 800 cm-1,1 450 cm-1~1 400 cm-1,1 350 cm-1~1 300 cm-1 and 1 100 cm-1~1 000 cm-1.The three kinds of infrared absorption modes were-CH stretching vibration mode,-OH deformation vibration mode and C-O stretching vibration mode.The main functional groups of jute fibers were changed significantly as the temperature increase.It is considered that thermal stability of jute fiber is the worse compared to flax and ramie fibers.
