Spinneret assembly for use in production of multi-ingredient multi-core composite filaments

摘要

A spinneret assembly to be fitted in a spinning pack for the production of multi-ingredient, multi-core composite fibers, each of which is comprised of at least three polymer phases. The assembly includes four plate members which form a plurality of series of linked polymer passages in which at least three of the plate members are capable of being assembled into a single unit by connecting means so that these plate members can be fitted in or detached from the spinning pack as a single unit.
