A MELT SPINNING APPARATUS AND PROCESS FOR SPINNING CONTINUOUS POLYMERIC FILAMENTS

Abstract A melt spinning apparatus for spinning continuous polymeric filaments including a first stage gas inlet chamber (105) adapted to be located below a spinneret (113) and optionally a second stage gas inlet chamber (106) located below the first stage gas inlet chamber. The gas inlet chambers supply gas to the filaments to control the temperature of the filaments. The melt spinning apparatus also includes a tube (119) located below the second stage gas inlet chamber for surrounding the filaments as they cool. The tube may include an interior wall having a converging section, optionally followed by a diverging section.
