Abstract

A spinneret for extruding a plastic polymer melt there-through to form fibers is disclosed in accordance with an embodiment of the present disclosure. The spinneret includes a plurality of apertures arranged along a plurality of contours to improve spinning productivity by enhancing aperture density while eliminating risk of filament fusion by maintaining appropriate aperture spacing.

Description

technical field [0001] The present application relates to a melt spinning process, in particular, the present application relates to a spinneret used in the melt spinning process. [0002] definition: [0003] Microdenier fibers / microfibers refer to synthetic fibers with a fineness of less than 1 or 1.3 denier or dtex / thread. [0004] Ultra-micro denier polyester filament refers to a synthetic fiber with an outer diameter of 0.37dpf (denier per filament) Background technique [0005] Polymer fibers are generally produced by a melt spinning process. In the melt spinning process, polymer is melted and the resulting polymer melt is pumped through a spinneret / die that has a plurality of holes distributed throughout it. The polymer melt is forced through a plurality of holes distributed in the spinneret / die resulting in the formation of molten fibers. Molten fibers extruded from distributed holes in the spinneret / die are cooled or quenched, solidified and collected on a wind-...
