ABSTRACT OF THE DISCLOSURE The invention relates to a bi-component filament or fibre of two different filament-forming synthetic polymers having a core/sheath structure in at least one component and having a moisture absorption of at least 1.5% at 65% relative atmospheric humidity and at a temperature of 21° C and a moisture absorption of at least 5% at 90% relative atmospheric humidity and 21° C and a water-retention-power of at least 10% as well as to a process for the production thereof in which the two different filament-forming polymers are placed eccentrically to each other in defined areas, according to a solution spinning process, which comprises adding to at least one spinning solution 5 to 50% by weight, based on the solvent and polymeric solid, of a substance, which is a) a non-solvent for the polymers to be spun, b) readily miscible with the spinning solvent and with water or another liquid used as washing liquid for the filaments or fibres so spun, and c) of a higher boiling point than the spinning solvent, and where necessary converting the filaments into fibres.
