AbstractImproved aromatic polyamide fibers from aromatic polyamides whose chain-extending bonds are either coaxial or parallel and oppositely directed are obtained by dry spinneret wet spinning into a shallow coagulating bath having an orifice in its bottom for removal of coagulating liquid and fibers wherein no more than a minor portion of coagulating liquid is lower than the entrance of the bath orifice in the proximity of the bath orifice. Preferably, no more than 10% of the coagulating liquid is lower than the entrance of the bath orifice and most preferably none of the coagulating liquid is lower than the entrance of the bath orifice.
