FIBROUS STRUCTURE OF META-FORM WHOLLY AROMATIC POLYAMIDE HAVING IMPROVED FEELING AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for improving feeling of meta-form wholly aromatic polyamide fibers hardened by dyeing and finishing and a fibrous structure produced by the method. SOLUTION: This method dying the meta wholly aromatic polyamide fibers including a flame retardant based on an onium salt of alkylbenzene sulfonic acid and aromatic condensation type halogen free phosphoric ester, by a cationic dye or the like and subjects after dying or in dying and after dying to treatments such as reduction cleaning or the like with a processing solvent including a polyalcohol type nonionic surfactant such as sorbitan or the like.
