Abstract
A method of producing a liquid crystalline polyester fiber includes subjecting a yarn prepared by melt spinning a liquid crystalline polyester to a solid-phase polymerization after applying inorganic particles (A) and a phosphate-based compound (B) to the yarn. The method can optionally include cleaning the liquid crystalline polyester fiber after the solid-phase polymerization.
