Abstract

Hydrophilic threads or fibres from an acrylonitrile homopolymerisate or an acrylonitrile mixed-polymerisate having at least 50% by mass of acrylonitrile units, having a water retention capacity of at least 40%, a resistance to tearing of at least 3 cN/dtex and an elongation at tear of at least 38%, are produced by wet- spinning a solution of the polymerisate in a non-aqueous spinning solvent, precipitation in an aqueous precipitation bath and, if desired, drawing and washing, and wherein 10 to 100% based on the polymer, of a liquid, organic, non-polar compound is added to the spinning solution which compound is such that a) it dissolves in the spinning solution; b) it does not dissolve in water and aqueous solutions of the spinning solvent, and c) it is not a solvent for the polymerisate. i
