A melt extrusion spinneret plate has at least one non-circular capillary
orifice for producing at least a single filament of circular
cross-sectional shape. This non-circular cross-sectional shape of the
extrusion capillary, when used to extrude filaments of circular
cross-sectional shape, extends the spinneret wipe life by lessening the
amount of thermal deposits, which extends the time between wipe cycles.
As a result of increased wipe life, the productivity of the process is
increased.
