Continuous process and apparatus for melt spinning of monofilaments

The invention relates to a continuous process for manufacturing monofilaments having a diameter of 60 mu m to 500 mu m from fibre-forming polymers by melt-spinning the polymer, optionally quenching the filaments with a cooling medium below the melt-spinning head, cooling the filaments in a liquid ba...

Beschreibung
Zusammenfassung:	The invention relates to a continuous process for manufacturing monofilaments having a diameter of 60 mu m to 500 mu m from fibre-forming polymers by melt-spinning the polymer, optionally quenching the filaments with a cooling medium below the melt-spinning head, cooling the filaments in a liquid bath having a temperature from -10 DEG C to 150 DEG C, removing the entrained water and aftertreating the filaments by spin-finishing, drawing and setting at a post-setting exit speed of the filaments of greater than 600 to 4000 m/min.
