Abstract
Hydrophilic polyacrylonitrile filaments or fibres where at least one filament-forming synthetic polymer is wet spun in a spinning solvent and wherein the spinning solvent has added to it from 10 to 20% by weight of a substance which is readily miscible with the spinning solvent and a washing liquid and is a nonsolvent for the polymer to be spun.
