Abstract

1346103 Spinneret for conjugate filaments IMPERIAL CHEMICAL INDUSTRIES Ltd 15 June 1972 [18 June 1971] 28765/71 Heading B5B A spinneret is provided for making eccentric sheath/core filaments having a D-shaped core. The spinneret comprises a spinneret plate 2 having a raised centre plateau 3 which is in contact with the back plate 7. Channels 4 are formed in the plateau and connect the annular space 8 between the spinneret plate 2 and back plate 7 with counter bores 6 and hence with extrusion orifice 5. In the back plate 7 there are formed D-shaped orifices 10 arranged vertically over the counter bores 6 in the spinneret plate 2. Sheath polymer is supplied from chamber 12 via supply port 14 channels 9 and annular space 8 to channels 4, where the core polymer supplied from chamber 13 via channels 15 and recess 16 is injected into it through D-shaped orifice 10. As shown in transverse section in Fig. 2, channels 4 preferably open out into a dilobate chamber under orifice 10.
