Keeping the other spinning conditons constant, just altering spinning solution solid content, PAN nas-cent fibers were prepared with DMO method by wet spinning. The fiber samples were characterized by centrifugal ma-chine.CMM-55 microscope and sound velocity measurement. Using twenty percent of the solid content in spinning solu-tion, the rusults showed that the PAN nascent fibers can be produced with circular cross section, compact, low boiling wa-ter shrinkage and better tropism.
