The invention relates to a process for the production of hydrophilic filaments and fibres from a filament-forming synthetic polymer by a wet- or dry-spinning process which comprises introducing into the spinning solvent from 5 to 50% by weight of a substance with special properties defined herein and from 0.05 to 5% by weight of at least one surface-active compound as well as to hydrophilic filaments and fibres produced by such process.

Process for the production of hydrophilic fibres and filaments of

The invention relates to polyester filaments and fibers and a process for the production of such polyester filaments and fibers which can be dyed in the absence of a carrier which comprises introducing into the polymer to be spun a silicate charged with an inert gas melt, spinning the mixture obtained in known manner and further processing into filaments or fibers.

Process for the production of polyester fibers and filaments which can

The invention relates to a process for the production of crosslinked fibres or filaments by spinning an acrylonitrile copolymer containing at least 20 mVal of carboxyl groups per kg of polymer together with a polyoxazoline in a polar organic solvent and thereafter crosslinking at temperatures of from 120 to 190.degree. C. The invention also relates to crosslinked acrylonitrile fibres and filaments obtainable by this process.
