    摘要: A method and apparatus for spinning filaments of a polymeric material includes a first temperature control arrangement for heating a spin pack to a first predetermined reference temperature greater than the predetermined polymer inlet temperature such that the temperature across a polymer filter holder and the spinneret plate in the spin pack is substantially uniform, whereby the temperature of the filaments emanating from the spinneret plate is substantially uniform. A plate assembly having at least one polymer flow passage therein is disposed between the outlet of the pump and the inlet of the spin pack. A second temperature control arrangement for independently controlling the temperature of the plate assembly to a second predetermined reference temperature is provided. The second predetermined reference temperature is selectable to a temperature above, equal to, or below the predetermined polymer inlet temperature, whereby the temperature of polymer conveyed through the polymer flow passage in the plate assembly is selectably controllable to a predetermined polymer temperature lying within a predetermined range of the second predetermined reference temperature.
