To produce a liquid-crystalline polymer shaped article which has excellent frictional resistance, abrasion-resistant characteristics and post-process passableness and hardly dropping fibrils.

This method for producing the liquid-crystalline polymer fiber is characterized by bringing a liquid-crystalline polymer solution into contact with a coagulating solution, in a process for producing a lyotropic liquid-crystalline polymer such as polybenzazole polymer, bringing the deposited crystalline polymer fibers into contact with a solid particle-dispersing liquid, and then winding up the formed fiber.
