-2- ABSTRACT A spinning head for producing multicomponent filaments. A spinning head for producing multicomponent filaments with matrix-filament structure. The spinning head comprises separate feed and distributing chambers for a least two synthetic polymer components each of differing properties and a die plate with a plurality of spinning openings. Each spinning opening is immediately preceded by its own mixing system for. combining the polymer components to form the matrix- filament structure,. The mixing systems each comprise a stack of metal foils. Each metal foil has a plurality of outer through flow openings at its periphery and/or one or more miner through flow openings at the centre. Some of the foils are also provided with radially extend- ing guide slots which communicate with the inner and/or outer through flow openings. The mixing systems allow the production of a stable filament cross-sectioned geometry with a controlled mutual association of the polymer components.
