SMELTSPINNINGSFORFARANDE FOR FRAMSTELLNING AV EN AKRYLNITRILPOLYMERFIBER

摘要

A single phase fusion melt of an acrylonitrile polymer and water is extruded into a steam-pressurized solidification zone maintained under conditions such that the continuous filament resulting retains sufficient plasticity so that stretching can be effected at a stretch ratio of at least about 25 relative to the linear speed of the single phase fusion melt through the spinnerette.
