Patent ID: 8871124

Claim:
A method for producing a filament yarn from an aromatic polyamide, comprising: filtering an optically anisotropic aramid spinning solution within a spinneret arrangement using a filter having passage openings; and extruding the filtered anisotropic aramid spinning solution within the spinneret arrangement through a plurality of spinning orifices, wherein: the extruded anisotropic aramid spinning solution is guided via an air gap, stretched in the process, and collected in an aqueous coagulation bath, the optically anisotropic aramid spinning solution in the spinneret arrangement is fed to the spinning orifices via a flow resistor, the flow resistor is arranged closer to the spinning orifices than the filter, the flow resistor and the filter are arranged at a distance to one another, the filter and the flow resistor have passage openings, the passage openings of the filter are smaller than the passage openings of the flow resistor, a diameter of the spinning orifices is large enough that a ball having a maximum diameter of z μm can pass through the spinning orifices, a size of the passage openings of the flow resistor is large enough that a ball having a maximum diameter of y μm can pass through the passage openings of the flow resistor, and z≦y.
