Patent

CA 2118478

The invention relates to a continuous process for the formation of monofilaments having a diameter of from 60 µm to 500 µm from filament-forming polymers by melt- spinning the polymer, optionally quenching the formed polymer filaments below the melt-spinning head with a cooling medium, cooling the filaments in a liquid bath having a temperature of from -10°C to 150°C, removing the entrained water and post-treating the filaments by spin finishing, drawing and fixing at a filament delivery speed which is greater than 600 to 4000 m/min after the fixing step.
