Abstract

Melt spinning experiments of tetrafluoroethylene copolymers, whose components are hexafluoropropylene (FEP), ethylene (ETFE) and perfluoroalkoxy vinyl ether (PFA), respectively, were carried out. When the conventional melt spinning machine with gear pump was used, desirable filaments were difficult to be obtained probably due to the degradation of polymers. The screw structure was designed to decrease the degraded polymer and to keep constant through-put of the polymer without using the gear pump. By the study of melt fracture, the diameter of the orifice was determined. The thinning of the filament during the spinline was controlled by the equipment of heated sleeve under the spinneret.
