The fibers are produced by polymerization and subsequent wet spinning. The PPTA polymer is dissolved in concentrated sulfuric acid and extruded through spinnerets. In the following air gap, the polymer strands in the liquid filament orient themselves to the fiber axis, which is a major factor later for the strength. Through further plugging processes, a fiber is created, which is formed from completely extended liquid crystal chains with a high degree of crystallinity. This leads to an increased fiber strength.
