采用变温傅里叶变换红外光谱（TD-FTIR）对羊毛、棉和苎麻的热性能进行了定性研究，采用热重-差热分析（TG-DSC）对羊毛、棉和苎麻的热性能进行了定量研究。TD-FTIR结果表明，虽然棉，苎麻和羊毛表现出显着的水损失，他们没有检测到的温度范围内从25？210？这些数据通过TG-DSC分析证实。动态力学热分析是对棉、麻、毛纤维束动态力学热性能的比较研究。四纤维束由于其较大的纤维接触表面和扭转变形而具有低得多的储能模量;加热在25 ℃至30 ℃的温度范围内显著降低了棉和苎麻的储能模量，而不是羊毛纤维束。到100？关键的E-T和tan-T曲线信息表明，苎麻纤维束具有最强的温度敏感性，而羊毛纤维束表现出最弱的温度敏感性。
Wool, cotton and ramie thermal properties are qualitatively studied by temperature-dependent Fourier transform infrared (TD-FTIR) spectroscopy, and quantitatively investigated by thermogravimetry coupled with a differential thermal analyzer (TG-DSC). TD-FTIR results indicate that although cotton, ramie and wool exhibit significant water loss, they have no detected degradation within the temperature range from 25? to 210?. These data are confirmed by TG-DSC analysis. Dynamic mechanical thermal analysis provides comparative study of cotton, ramie and wool bundles' dynamic mechanical thermal properties. The four-fiber-bundle has a much lower storage modulus due to its larger fiber contact surface and twisting deformation; heating reduces the storage modulus significantly for cotton and ramie instead of wool fiber bundles in the temperature range from 25? to 100?. Key E-T and tan-T curve information reveals that ramie fiber bundles have the strongest temperature sensitivity, while wool fiber bundles express the weakest temperature sensitivity.
