Abstract
Aramid fibers, polybenzimidazole fibers or blends of aramid and polybenzimidazole fibers are rendered flame resistant by a flame retardant introduced into the fibers by a polar organic swelling agent such as DMSO. Dyed or undyed fibers so treated exhibit substantially improved flame resistance as compared with untreated fibers.
