Dope-dyed Meta-Aramid Fiber having excellent color and Method for producing the same

摘要

The present invention relates to a method for manufacturing a dope-dyed aramid fiber having excellent color, comprising: (S1) forming a meta-aramid dope by dissolving a meta-aramid polymerized with M-phenylene diamine (MPD) and isophthaloyl chloride (IPC) in a polar amide solvent; (S2) diluting a pigment in the polar amide solvent to form a pigment dope; (S3) introducing the pigment dope into the meta-aramid dope to form a meta-aramid-pigment mixture; (S4) introducing the meta-aramid-pigment mixture into the meta-aramid dope; and (S5) spinning the agitated product formed by agitating after the step (S4).
