摘　　要：以涤/棉股线作为芯纱,二醋酸纤维素纤维作为绒纱,利用雪尼尔纺纱机纺制二醋酸纤维素绳绒线,并对纱线性能与烟气过滤性能进行了研究。与传统卷烟滤嘴中二醋酸纤维丝束的轴向排列不同,所纺纱线中二醋酸纤维丝束沿垂直于烟气的流向排列,纤维排布结构新颖。研究表明,该结构绳绒线对烟气成分的吸附量普遍较低;采用颈宽2.2 mm的隔距片纺制纱线,并制成滤嘴样品,烟气经过后气溶胶捕集量(ACM)的剩余量(进入抽吸者口中的量)为40.03 mg/支,水分剩余量为21.96 mg/支,烟碱剩余量为1.98 mg/支,焦油剩余量为15.86 mg/支,甘油剩余量为1.89 mg/支;其在模拟抽吸香烟过程中的降温效果更明显且吸阻最小,抽吸体验更佳。Cellulose diacetate chenille yarn is successfully spun with the terylene/cotton(T/C)as the core yarn and the cellulose diacetate fibers as the pile yarn via a chenille spinner,and its comprehensive performance and flue filtration performance are investigated.The arrangement direction of the diacetate fiber bundles in as-spun yarns is perpendicular to the direction of smoke flow,which is different from the conventional cigarette filters(axial arrangement)with an innovative arranged structure.The results demonstrate that the brushed chenille yarn exhibites the low absorption capacity.The comprehensive performance of as-spun cellulose diacetate chenille yarn by a spacer with 2.2 mm neck width is commendable.The adsorption capacity for aerosol capture per cigarette of carbonyl compounds(ACM),moisture,nicotine,tar and glycerol of sample II are 40.03,21.96,1.98,15.86 and 1.89 mg/cig,respectively.The temperature drop and the suction resistance from sample II as the cigarette filter are the most appropriate than those of other samples,indicating it can provide a better smoking sense for the consumers.
