Abstract (en)

A method and apparatus for spinning bicomponent sheath/core filaments is disclosed. The spinneret assembly for the production of sheath/core bicomponent filaments comprises a distributor (10) having a plurality of spaced core polymer flow passages (17) and multiple sheath polymer flow passages (16), a spinneret (12) having a plurality of spaced core polymer flow passages (22) and multiple sheath polymer flow passages (23), a shim means (11) positioned between said spinneret and said distributor for spacing said spinneret from said distributor and for controlling the sheath polymer flow from the outlet of said distributor sheath polymer flow passages to the inlet of each said spinneret core polymer flow passage separately. <IMAGE>
