ABSTRACT OF THE DISCLOSURE The invention relates to a process for the production of hygroscopic filaments and fibres from a filament-forming synthetic polymer by wet or dry spinning from a spinning solvent, which comprises introducing into the spinning solvent A) from 5 to 50 % by weight, based on the solvent and polymer solids, of a substance which is not surface active and which: a) has a higher melting or boiling point under normal conditions than the spinning solvent used; b) is readily miscible with the spinning solvent and with a liquid used as a washing liquid, and c) is a non-solvent for the polymer to be spun, and B) from 0.05 to 5 % by weight, based on polymer solids, of at least one surface-active compound, spinning the spinning solvent mixture thus obtained to yield spun filaments and during which spinning the solvent is substantially removed, after-treating the spun filaments during which after treatment said non-solvent substance A) is substantially removed, and, where necessary, converting the filaments into fibres, as well as to hygroscopic synthetic filaments and fibres, which resemble natural fibres, produced by such process.
