More Information
Summary:In a method of producing hydrophilic threads or fibres from an acrylonitrile homopolymerisate or an acrylonitrile copolymerisate by dry- spinning or wet-spinning of a solution of the polymerisate in a non-aqueous organic solvent, coagulation of the threads and subsequent drawing, washing and drying, the water contained in the threads is replaced by organic liquids that do not dissolve the polymerisate, prior to drying of the threads. Preferably the organic liquids are water soluble mono- or polyhydric alcohols, ketones or cyclic ethers optionally mixed with water-insoluble organic liquids.
