Abstract

The invention relates to a continuous process for the formation of monofilaments having a diameter of from 60 .mu.m to 500 .mu.m 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.degree. C. to 150.degree. 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.
