摘要: <正> 在各类刑事和民事案件中,常遇到纺织品一类物证,因此纺织品的鉴别和同一认定在司法鉴定实践中有重要的价值。纺织品的鉴别主要包含二个方面:制成纺织品的原料纤维的化学组成和纺织品的色泽、染色时使用的染料种类。颜色有明显差别的纺织品检材,一般用

Abstract: The identification and recognization of textile fibers by using differ- ential scanning calorimetry (DSC) technique is deteiled.In this study we mainly applied the DSC to identify the fibers dyed with a type of dye in different concertration and identify a kind of dye in different type.The results are showed that:a,the DSG method can be used to identify the dyes in the same or similar colour but in different types,bs the DSC curves of dyed fibers appeared not only the fibers special peaks but also the new special peak that dyes act on fibers.
