    摘要: A meta-type wholly aromatic polyamide containing, as principal repeating units, meta-phenylenediamineisophthalamide units is dissolved in an amide compound solvent; the resultant polymer solution is subjected to a wet-spinning procedure wherein the polymer solution is extruded in the form of filamentary streams into a coagulation bath containing an amide compound-containing solvent and water but substantially not containing salts, through spinning orifices of a spinneret, to coagulate the extruded filamentary polymer solution streams in the coagulation bath; the coagulated porous undrawn filaments are subjected to a drawing procedure wherein the porous undrawn filaments are drawn in a plasticizing drawing bath containing an aqueous solution of an amide compound solvent; the resultant drawn filaments are washed with water, and then heat-treated (for example, further drawn at a draw ratio of 0.7 to 4.0 while being heated at a temperature of 250 to 400° C.), to provide uniform and dense meta-type wholly aromatic polyamide fibers.
