摘　　要：采用差示扫描量热(differential scanning calorimetry,DSC)技术,对10种标准纤维类样品和5种自行制备的涤纶-棉混纺纤维样品进行定性和定量分析.结果表明,DSC方法可以实现多种纤维类样品的定性分析.涤纶-棉混合纤维样品的定量分析表明,DSC方法有望实现混纺类纤维样品的定量分析,涤纶-棉混合纤维的定量分析绝对误差小于3.0%.We use differential scanning calorimetry （ DSC ） to examine ten pure standard fiber samples and five polyester-cotton composite fiber samples to look for fiber evidence. The results show that the characteristics of DSC curves such as typical molten peak shape and position can serve as the useful criteria for differentiating fiber samples. Quantitative analyses of polyester-cotton composite fiber samples yield precise results with absolute errors generally being less than 3. 0%, which confirms the feasibility of using the DSC method for forensic identification.
