LIQUID CRYSTALLINE POLYESTER FIBER, LIQUID CRYSTALLINE POLYESTER FIBER CLOTH AND METHOD FOR PRODUCING LIQUID CRYSTALLINE POLYESTER FIBER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a liquid crystalline polyester fiber capable of forming a fiber cloth sufficiently thinned.

SOLUTION: The suitable embodiment of the production method of a liquid crystalline polyester fiber comprises a step of dispersing a solution by electric field in electrostatic field to form a liquid crystalline polyester fiber, in which solution is obtained by dissolving a liquid crystalline polyester and a fiber-forming polymer in a solvent. By the production method, the liquid crystalline polyester fiber having 0.01-1μm average fiber diameter is easily obtained.
