The gel dynamics experiments showed that the gel formation law was similar with the other polymer systems, which wasrelated with dense surface under the soft coagulating condition and the thickening gel; the square of gel thickness was linear with coagulation time. The qualitative analysis of the surface puckers of fibers spun from wet spinning and dry-jet wet spinning was made. The positions where the die swell appeared were not the same and the die swell appeared at the air gap where the fiber would markedly been elongated and vary little in the coagulant, thus the surface of fiber spun from dry-jet wet spinning was more smooth. The radial component concentration gradient was responsible for the radial structure of PAN fiber spun from dry-jet wet spinning. The thicker surface with microvoid structure of

The research shows that, when fluidized gas is used only, it had little effect on the quantity of returning solids, and that the effect of loosed gas is significant. Horizontal opening has distinct effect on the circulating rate only when the loosed gas is larger; the appropriate horizontal opening is corresponding to the gases quantity. The combining of the arced gas distributor and the gases regulating could eliminate the fluidized dead zone in the U-valve effectively.
