Abstract
A method is provided for producing fine denier multicomponent thermoplastic polymer filaments incorporating high melt-flow rate polymers. Multicomponent filaments are extruded such that the high melt-flow rate polymer component is substantially surrounded by one or more low melt-flow rate polymer components. The extruded multicomponent filament is then melt-attenuated with a significant drawing force to reduce the filament diameter and form continuous, fine denier filaments.
