发明名称 Process for drawing polyamide monofilaments
摘要 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.
