摘要: A coupled spin-draw process for making a fully-oriented nylon yarn including extruding molten nylon polymer with a selected RV through a spinneret and cooling to produce a yarn. The yarn is withdrawn from the quench zone with a feed roll rotating at a speed of at least 4500 mpm. The process further includes cold drawing followed by relaxing the yarn using a steam intermingling jet and then winding up.
