A wholly aromatic polyamide composition which is suitable for producing filaments or fibers having not only an excellent heat-resisting property but also, a superior dyeing property, which comprises:
(A) 50 to 95% by weight of poly-m-phenylene isophthalamide, and
(B) 5 to 50% by weight of at least one other aromatic polyamide comprising:-
(1) an amine moiety consisting of essentiatly of (a) 35 to 100 molar % of at least one phenylene diamine in which the phenylene group has 1 to 4 substituents respectively selected, independently from each other, from the group consisting of halogen atoms and alkyl radicals having 1 to 4 carbon atoms, e.g. 2,4-diaminotoluene, and (b) 0 to 65 molar % of at least one other aromatic diamine, and;
(2) an acid moiety consisting essentially of at least one aromatic dicarboxylic acid, e.g. terephthalic or isophthalic acid.
