Verfahren zur Herstellung von Bikomponentenfaeden

摘要

Production of a two-component unitary filament having a given uniform cross-sectional configuration and comprising sheath and core portions consisting of a first and a second synthetic polymers respectively, and produced by separately fluidifying said polymers and simultaneously and concurrently feeding both polymers through a common spinneret orifice for extruding therefrom a composite filament, wherein the said second polymers forms a part of its cross-section, said part being both inwardly and outwardly enclosed by said first polymer and its major portion is located outside the concentric one-half similar shape of the cross-section of the filament.
