A spinnerette assembly for spinning polymerized fibers

摘要

A spinneret assembly for spinning polymeric fibers, comprising: (a) a cap having an inlet port and a flared lower surface extending outwardly from the inlet port in a flow direction; (b) a spinnerette having a plurality of radial flow channels through its thickness; (c) a filter lying freely on the spinneret; And (d) a flow guide having a tapered geometry mounted within the cavity defined by the cap and the spinnerette. The flow guide has a vertex toward the inlet port, a base toward the filter, and at least one side that is tapered to the vertex. The diverging flow passage is defined by the tapered side of the flow guide and the lowered side of the cap. The base of the flow guide is spaced from the top surface of the spinnerette to create a space in fluid communication with the diverging flow path.
