PURPOSE: To obtain the subject fiber excellent in abrasion resistance by providing an aliphatic lubricant layer through a film of a polyether-based compound on the surface thereof in which a solid cationic exchangeable and nonionic adsorptive inorganic compound is adhered.

CONSTITUTION: Wholly aromatic polyamide fiber obtained by providing an aliphatic lubricant layer (incompatible with a polyether-based compound, soluble in water and having ≤900 molecular weight) through a film of the polyether- based compound on the surface thereof in which a solid cation exchangeable and nonionic adsorptive inorganic compound is adhered. The polyether-based compound contains a polyoxyalkylene which is a liquid at ≥15°C and has ≥10000 molecular weight.
