In order to study qualitatively the flying and themechanism of its generation in the production process of cellu- lose acetate, MALLS-GPC, DSC and SEM were used to characterize the flying. The results showed thatmolecularweight and its distribution, the synthesis process of cellulose diacetate, the gel com- ponent and titanium dioxide particles in spinning dope, and the fluctuation of spinning technical conditionswerem ain factors responsible for the generation of flying. 　　 ,, 。, , 。,, , (Flying)。 , , , ,, :(1977 - ), , 。 , 、 。 E- mai:l mxl@ncfcinfo. com　:05134616 [1-2] :2006 -
