ABSTRACT:
Conjugate filaments containing components located in a side-by-side or eccentric sheath/core structure are formed by directing superposed layers of the polymer components across the surface of a spinneret plate into narrow channels, the channels being contained in a member integral with the spinneret plate, to form narrow streams which are extruded through extrusion orifices located below the narrow channels in a spinneret plate.
