META TYPE WHOLLY AROMATIC POLYAMIDE FIBER AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new method capable of producing a meta type wholly aromatic polyamide fiber without having close adhesion among fibers and having good dynamic characteristics and thermal properties efficiently in an industrial production level. SOLUTION: This method for producing the wholly aromatic polyamide fiber is provided by wet spinning the meta type wholly aromatic polyamide polymer solution obtained by dissolving the meta type wholly aromatic polyamide having a metaphenyleneisophthalamide skeleton as a main component in an amide-based solvent, under a specific condition.
