Melt spinning process for acrylonitrile polymer fiber-three or more stretch stages |
摘要 |
Extrusion of a single phase melt of acrylonitrile polymer and water directly into a steam-pressurized solidification zone and stretching the nascent extrudate in at least three stages while it remains within the solidification zone provides fiber which is readily relaxed.
