A process is disclosed for producing a multifilament yarn from a molten thermoplastic polymer comprising melt-spinning of the thermoplastic polymer, extruding the molten thermoplastic polymer through a spinneret to form a plurality of filaments, and passing the filaments through a cooling zone to enable the spun filaments to be solidified to produce an undrawn yarn, applying a primary spin finish to the undrawn yarn and continuously drawing the undrawn yarn in one or more stages to produce a drawn yarn, applying a secondary spin finish during or after drawing and subsequently winding the drawn yarn, wherein the yarn temperature when entering the secondary spin finish is greater than 150 °C, that the secondary spin finish contains one or more adhesion activating components in an oil based composition and that the oil based composition consists of components with an evaporation rate of less than 10 wt.-% at the given yarn temperature. |
