<p>A single phase fusion melt of acrylonitrile polymer and water is melt-spun into a pressurized solidification zone wherein certain temperature, pressure, and composition conditions obtain. After spin-drawing the nascent extrudate in the solidification zone, it may be relaxed in a free-to-shrink condition. In a preferred embodiment, the nascent fiber is dried at elevated temperature before it is cooled or before it loses water upon cooling.</p> |
