摘要

TITLE A CO-SPUN FILAMENT WITHIN A HOLLOW FILAMENT AND SPINNERET FOR PRODUCTION THEREOF A hollow fiber which contains within the hollow a co-spun hollow or solid filament. The solid filament is formed of polymer that can distribute energy within the hollow fiber while a co-spun hollow inner filament can also act as a vessel for transportation or separation of fluids.
