ABSTRACT:
A cartridge filter is provided in which a powdered filter medium is encapsulated between screens which are sealed to the side wall of the cartridge. The side wall has a flange which engages the upper surface of a holder into which the cartridge fits. The holder is part of a spin-pack assembly in which the cartridge filters fiber-forming material immediately before the material passes through spinneret capillaries and is formed into filaments.
