摘　　要：利用DTG和DSC技术对再生竹纤维素纤维的热学性质进行了测试和分析,测试结果显示,再生竹纤维素纤维的DTG和DSC曲线与其他纤维素纤维相似,随着温度升高,纤维因水分蒸发而损失质量,约120℃时达到稳定;230-240℃时,纤维中的油剂开始分解;空气中,再生竹纤维素纤维305.7-330.2℃发生热裂解;氮气中,竹纤维素纤维的热裂解从310.5℃开始,到351.1℃结束。竹纤维素纤维在升温过程中没有出现熔融现象,其湿润状态下的断裂强力和断裂伸长率均较干态为低。Thermal and tensile properties of regenerated bamboo fiber are tested and analyzed by use of DTG and DSC technics. DTG and DSC curves of the fiber are similar to those of cellulose fiber. With the increase of temperature, the water in the fiber evaporates and the weight of the fiber decreases and it becomes stable when the temperature reaches 120℃. The finishing oil in the fiber begins to decompose at 230 - 240 ℃. Thermal cracking phenomenon of the regenerated fiber takes place at 305.7 to 330.2℃ in air while it happens at 310.5 ℃ and ends at 351.1 ℃ in nitrogen atmosphere. The fiber can not be melted in the process of heating. The broken tenacity and elongation of the fiber in dry state are higher than that in wet state.
