摘　　要：为了研制能够改善卷烟感官质量的二醋酸纤维素丝束,采用在纺丝乳液中添加增香保润剂的方法,进行改性纺丝乳液和改性丝束的生产应用。利用乳液蓝光检测法、Zeta电位法和激光粒度法分析了4种增香保润剂(A为不饱和脂肪酸,B为聚氧乙烯磺酸化物,C为苋科植物提取物,D为葡萄糖苷)对纺丝乳液的性能影响,并对相应改性丝束进行了烟气分析和感官评价。结果表明:1Zeta电位是表征添加增香保润剂的改性纺丝乳液稳定性的主要指标,Zeta电位增加,乳液稳定性提高;与对照纺丝乳液相比,添加增香保润剂的改性纺丝乳液蓝光现象减弱、乳液粒径增大。2添加增香保润剂的改性丝束的理化性能指标与对照丝束保持一致,满足烟用丝束品质要求。3与对照丝束卷烟相比,添加增香保润剂的改性丝束卷烟样品的感官质量有所提升,烟气过滤效率略有下降。增香保润剂改善卷烟样品感官质量的贡献顺序为C>D>B>A。In order to obtain modified cellulose acetate fibers that could improve the sensory quality of cigarette,a modified filter tow was produced via adding flavored humectants into spinning oil.The effects of four humectants（A-unsaturated fatty acid,B-polyoxyethylene sulfonate,C-Amaranthaceae extract,D-glucosidase） on the modified spinning oils were analyzed by blue light detection,Zeta potentiometry and laser particle size analysis,the corresponding modified tows were subjected to smoke analysis and sensory evaluation.The results showed that：1） Zeta potential was the main indicator characterizing the stability of spinning oil modified by flavored humectants,the stability of spinning oil improved along with the increase of Zeta potential.Comparing with the control,the blue light phenomenon of the modified oils weakened,their particle size increased.2）The physicochemical properties of the modified tows were identical to those of normal tow and satisfied the quality requirements for cigarette filter tow.3） Comparing with normal tow,the sensory quality of cigarette samples with modified tows promoted slightly,while smoke filtration efficiency decreased slightly.The four flavored humectants in the order of their contribution to cigarette sensory quality were C〉D〉B〉A.
