| 摘 要： | 为研究烟用二醋酸纤维生产过程中的飞花及其产生机理,采用多角激光散射检测器与凝胶渗透色谱联用、差示扫描量热和电子扫描电镜等方法对飞花进行了表征。结果表明,分子量及其分布、醋酸纤维素的合成过程、纺丝浆液中的凝胶组分和二氧化钛颗粒以及纺丝工艺条件的波动等是造成飞花的主要因素。

| Abstract: | Flying is one of the important indexes in cellulose acetate quality evaluation. In order to study qualitatively the flying and the mechanism of its generation in the production process of cellulose acetate, MALLS-GPC, DSC and SEM were used to characterize the flying. The results showed that molecular weight and its distribution, the synthesis process of cellulose diacetate, the gel component and titanium dioxide particles in spinning dope, and the fluctuation of spinning technical conditions were main factors responsible for the generation of flying. |
