Method for melt spinning of multiple multi-filament threads from spinning nozzle, involves dividing filaments from filament groups into multiple sub-bundles and separately connecting filaments of sub-bundles to one of multiple threads

摘要

The method involves generating multiple partial melt flows and separately supplying the partial melt flows over multiple melt inlets (3.1,3.2) of a spinning nozzle (2). The partial melt flows are separately filtered inside the spinning nozzle and are separately extruded to multiple groups of filaments (14.1,14.2). The filaments of the sub-bundles are separately connected to one of the multiple threads (16). The partial melt flows of a spinning pump (12) are generated with equal-sized or different sized volume flows of polymer melts. An independent claim is included for an apparatus for melt spinning of multiple multi-filament threads from a spinning nozzle.
