Apparatus for spinning bicomponent filaments

摘要

A spinning assembly for use in a process for the production of sheath/core bicomponent fibres comprising a spinneret plate having at least one counter-bore terminating in an extrusion orifice, a distributor plate spaced apart from but facing the spinneret plate to provide a liquid channel therebetween for communication with a source of sheath-forming material, the distributor plate being provided with an aperture opposite each orifice in the spinneret plate for communication with a source of core-forming material and a plateau-like protrusion on the distributor plate extending about the axis common to the aperture and the extrusion orifice characterised in that there is provided an orifice plate for restricting the entrance to the counter-bore.
