摘要

An aromatic polyamide fiber comprising an aromatic polyamide containing a structural repeating unit of the following formula (1), and a structural repeating unit of the following repeating unit (2) in an amount of 30 mol% or more to the whole amount of the aromatic polyamide structural units, the fiber having strength of 20 cN/dtex or more and modulus of elongation of 500 cN/dtex or more:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-CO-Ar 1 -CO-NH-Ar 2 -NH-€ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein Ar 1 and Ar 2 each independently represent an unsubstituted or substituted divalent aromatic group.
