seen and device for framstellning of one of at least two synthetic polymer components permanent flerkomponentstrad

摘要

A multi-component filament consisting of at least two polymer components and having a cross-section in which a matrix component separates several peripherally arranged segments of one or more segment components from each other, and a process for the production of such matrix/segment filaments, wherein the segment component is injected into the matrix component and fed to the spinneret opening in a combined stream with a plurality of segment components separated by the matrix. The multicomponent filament can be drawn to obtain individual microfilaments of less than 1 dtex after splitting, e.g. by false twist texturing.
