Abstract
A poly-p-phenylene-terephthalamide fiber with excellent fatigue resistance resulting from a unique combination of properties. The fibers are prepared by extruding an anisotropic polymer dope in a non-coagulating layer, passing the extrudate through a coagulating layer, depositing the resulting coagulated fibers on a net conveyor, and in the absence of substantial tension sequentially washing the fibers, holding the fibers in saturated steam, and drying the fibers under specified conditions.
