Relationship between Technics and Properties during PAN Precursors Formation Process
In order to release the relationship between technics variables and properties of PAN fiber, the evolvement of crystalline structure of PAN fiber during the wet spinning process was studied by X-ray diffraction(XRD), the measurement of the solvent residuals, boiling-water shrinkage and breaking tenacity. It is found that the drawing and removal of solvent can improve the tenacity, especially the drawing can improve degree of orientation and crystallinity, and the collapse process can stabilize the orientation and crystalline structure.
