Heavy denier, polyamide monofils are produced by the coupled steps of spinning, quenching, drawing and winding. Quenching involves passage of the filament through an air gap and a water bath. There are two stages of drawing. In the first stage, pressurized steam is used to deorient surface polymer and as a draw assist. The product is characterized by a surface layer of oriented polymer having reduced orientation relative to the orientation of the core polymer.
