Abstract

A fiber of modified Wholly Aromatic Polyamide containing at least 85 mole % of recurring structural units represented by the following formulas (I) or (II): [NR1-Ar1-Nr2-CO-Ar2-CO] (I) [NR3-Ar3-CO] (II) Ar1, Ar2 and Ar3 are aromatic radicals, Ar1 and Ar2 are the same or different; R1, R2 and R3 are lower alkyl group or hydrogen, and R1 and R2 are the same or different, and containing at least 0.2 mole % of recurring structural units in the polymer main chain as represented by the formulas (III) -[NH-Ar1-NH-CO-Ar2-CO]- or [NH-Ar3-CO]- SO3M SO3M where M is hydrogen, a quaternary ammonium ion or a metal cation.
