Abstract (en)
[origin: WO9412704A1] Polybenzazole fibers can be rapidly dried without undue fiber damge by exposing them to two or more set point temperatures with the temperatures being selected relative to the residual moisture content of the fiber. The residence time required for the fiber at each progressively higher temperature can be reduced if the fiber is always in full contact with the set point temperature of the drying equipment.
