Spinneret for producing circular cross section yarn and process for making the same |
摘要 |
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.
