Abstract: Molten polyamide filaments (10) are extruded from spinneret capillaries through a gas-filled gap (12) and into a quench bath (13) which contains a heated aqueous liquid. The bath has a nozzle defining a vertically disposed cylindrical passageway with its entrance in the bath below the bath surface. The filaments are converged into a filament bundle at the entrance and withdrawn from the exit of the passageway at a withdrawal speed of about 1500 to about 3500 meters per minute. The polyamide polymer is extruded from the spinneret such that the jet velocity in the spinneret capillaries is between 2 and 10 % of the withdrawal speed of the filament from the exit of the nozzle passageway.
