LIQUID CRYSTAL POLYESTER FIBER, AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal polyester fiber having further excellent processability in a high-order processing step with little defects and fibrils without fusion among single yarns even when solid-phase polymerization is performed in a package form. SOLUTION: In the liquid crystal polyester fiber and a method for producing the same, applying inorganic particles and a polysiloxane to a fiber obtained by carrying out melt spinning of a liquid crystal polyester, and then performing the solid-phase polymerization.
