摘要
通过显微镜观察法、热重分析法(TG)和差示扫描量热仪法(DSC)研究了智能调温纤维的外观形态和热学特征,对DSC条件(温度范围、升温速率、样品量和循环次数)进行筛选,优化了测试条件。结论显示,智能调温纤维的DSC曲线,在0~50℃范围内,以20℃/min的速率升温可得到一个熔融峰,再以20℃/min的速率降温可得到一个结晶峰的方法可测定纤维具有智能调温功能。
The appearance shape and thermal property of thermal regulated fiber were tested by the methods of microscope,TG and DSC. The test conditions for DSC such as temperature range,heating rate,sample amount and cycles were selected and optimized. The results showed that DSC curve of thermal regulated fiber was between 0~50 ℃,and melting peak was arrived when warming up at the speed of 20℃/min.
