Zusammenfassung:	A method is provided for producing fine denier multicomponent thermoplastic polymer filaments incorporating high meltflow rate polymers. Multicomponent filaments are extruded such that the high meltflow rate polymer component is substantially surrounded by one or more low meltflow rate polymer components. The extruded multicomponent filament is then meltattenuated with a significant drawing force to reduce the filament diameter and form continuous, fine denier filaments. Se proporciona un metodo para producir filamentos de polimero termoplastico de multicomponentes de denier fino incorporando polimeros de tasa de flujo de derretido alto. Los filamentos de multicomponentes son extruidos de manera que el componente de polimero de tasa de flujo de derretido alto esta esencialmente rodeado por uno o mas de los componentes de polimero de tasa de flujo de derretido bajo. El filamento de multicomponentes extruidos es entonces atenuado con fusion con una fuerza de jalado significante para reducir el diametro de filamento y formar filamentos de Denier fino continuos.
