<p>The invention relates to a high speed melt-spinning process for producing polyamide filaments characterised by the steps of: (a) mixing an additive into a melt-spinnable polyamide polymer, so that the resulting polymer mix is homogenous, the additive having a molecular weight less than 400 and being a member selected from the group consisting of water, alcohols, and organic acids, the additive being mixed in a amount so that on extrusion, the molten polymer mix has a relative viscosity between 2.0 and 3.0; and (b) extruding the resulting molten polymer mix through a spinnerette so that polyamide filaments are formed; and (c) quenching the so formed filaments; and (d) taking up the quenched filaments at a speed which is greater than 3200 meters per minute.</p> |
