摘　　要：制备了谷胱甘肽添加质量分数为1.52%的纺丝乳液,通过丝束上油过程将谷胱甘肽均匀附着在纤维表面以实现对醋酸纤维丝束的表面改性。对改性醋酸纤维丝束的物理性能、表面形态、常规烟气、烟气自由基等项目进行了分析。结果表明,改性醋酸纤维丝束的物理加工性能与常规醋酸纤维丝束接近;由改性醋酸纤维丝束加工的滤嘴过滤后,卷烟烟气中焦油含量同比下降了1.08 mg支/;粒相自由基含量同比下降21.34%,气相自由基含量同比下降25.07%。Emulsion containing 1.52% mass fraction glutathione was prepared. Glutathione was coated on the surface of fibers via oil process, and the chemical properties of the cellulose acetate tow were modified. We analyzed the physical properties and surface morphology of the modified cellulose acetate tow. The contents of the common components and free radicals in cigarette smoke were also analyzed, The results showed that the manufacturing properties of the modified cellulose acetate tow were similar to that of common tow. The tar content in main smoke was reduced by 1.08 mg. The particulate-phase and gas-phase free radicals in the smoke can be reduced by up to 21.34% and 25.07%.
