Method for testing polymer melt, involves producing polymer melt through melt source, and determining parameter i.e. purity level, of polymer melt with melt streams, where melt streams are supplied to extrusion bodies

摘要

The method involves producing polymer melt through a melt source, and feeding the polymer melt to an extrusion process with parallely operated extrusion bodies (20.1-20.4) in multiple partial melt streams. A parameter i.e. purity level, of the polymer melt is determined with the melt streams, where the melt streams are supplied to the extrusion bodies. The melt streams are supplied to a measuring device in the bodies, where the measuring device is held for exchanging extrusion dies (21.1-21.4) at the bodies. Multiple strand-shaped filaments are extruded in the bodies by a spinneret (22). An independent claim is also included for a measuring device for testing a polymer melt.
