摘　　要：通过燃烧法、溶解法和红外吸收光谱法对烟用二醋酸纤维素丝束与烟用聚丙烯丝束鉴别特征进行研究。结果表明:(1)二醋酸纤维素丝束的燃烧状态、燃烧过程中的气味、燃烧残留物的状态均与聚丙烯丝束有明显差异,通过燃烧法可以鉴别两种丝束的类型;(2)二醋酸纤维素丝束能溶于浓度为70.0%以上的丙酮溶液,而聚丙烯丝束则完全不能溶解,通过溶解法可以鉴别两种丝束的类型;(3)二醋酸纤维素丝束和聚丙烯丝束的红外特征图谱有明显差异,通过红外吸收光谱法可以鉴别两种丝束的类型;(4)验证实验表明,燃烧法、溶解法和红外吸收光谱法鉴别丝束类型的实验重复性和再现性较好,各实验室的鉴别结果完全一致。通过以上实验方法,可以鉴别二醋酸纤维素丝束和聚丙烯纤维丝束的类型。In this paper,the identification characteristics of cellulose diacetate tow and polypropylene tow for cigarette were studied by combustion method,dissolution method and infrared absorption spectrometry.The results show that:(1)The combustion state,smell during combustion and the state of combustion residue of cellulose diacetate tow are significantly different from those of polypropylene tow.The two tow types can be identified by combustion method.(2)Cellulose diacetate tow can be dissolved in acetone solution with a concentration of more than 70.0%,while polypropylene tow can not be dissolved at all.The two tow types can be identified by dissolution method.(3)The infrared characteristic spectra of cellulose diacetate tow and polypropylene tow are obviously different,and the types of the tow can be identified by infrared absorption spectroscopy.(4)The validation experiment shows that the combustion method,dissolution method and infrared absorption spectrometry have good repeatability and reproducibility in identifying tow types,and the identification results of each laboratory are completely consistent.Through the above experimental methods,the types of cellulose diacetate tow and polypropylene fiber tow can be identified.
