HYDROPHILIC FIBRES AND FILAMENTS OF SYNTHETIC POLYMERS
The invention relates to dry-spun filaments or fibers with porous structures of filament-forming synthetic polymers with a moisture absorption of at least 2 % at 65 % relative humidity and at 21.degree.C and with a water retention capacity of at least 20 % as well as to a process for their productio...

| description | The invention relates to dry-spun filaments or fibers with porous structures of filament-forming synthetic polymers with a moisture absorption of at least 2 % at 65 % relative humidity and at 21.degree.C and with a water retention capacity of at least 20 % as well as to a process for their production from filament-forming acrylonitrile polymer by dry spinning in a spinning solvent, which comprises introducing into the solvent from 5 to 50% by weight, based on the total solvent and solids, of an additive substance which is solid under normal conditions and which:a) has a higher melting or sublimation point than the spinning solvent used;b) is readily miscible with the spinning solvent and with a washing liquid; andc) is a non-solvent for the polymer to be spun, and washing the additive substance out of the freshly spun filaments and where required converting the filaments into fibers. The novel hydrophilic filaments and fibers resemble natural fibers. |
