Definitions

  • the invention relates to a method for producing fibers from polyetherimide and fibers from polyetherimide.
  • a method for producing such fibers has become known from DE-OS 28 29 811. They are made by spinning solutions of polyamic acids in an aprotic organic solvent into a spin bath, after which the freshly spun fibers must be stretched and heat treated to obtain useful textile data.
  • the object of the present invention is to provide an economical process for producing a high-temperature-resistant polyetherimide fiber which can be further processed in the usual manner. It is also an object of the present invention to provide such a fiber.
  • melt-spun fiber made of polyetherimide. This fiber is characterized by the features set out in claims 6 to 9.
  • the fibers according to the present invention have excellent textile properties, as shown in FIGS following examples can be seen. They can be processed further on conventional textile machines, in particular stretched and / or textured. It is therefore readily possible to texturise yarns from these fibers simultaneously or sequentially. It is also possible to use the usual air jet blowing processes.
  • fibers are understood to mean both continuous filaments and staple fibers.
  • Fibers made of polyetherimide are understood to mean those fibers which, as a polymer, contain exclusively at least almost exclusively polyetherimide.
  • the object of the invention is also achieved by a melt-spun monofilament made of polyetherimide.
  • the fibers or monofilaments according to the invention can also contain further polymers, such as, for example, polyethylene terephthalate and / or polyamide.
  • Bi-component fibers or monofilaments belong to this group.
  • Bi-component monofilaments made of polyetherimide in the sheath and polyethylene terephthalate in the core are ideal, for example, for the production of hydrolysis-resistant screens or filters, for example for paper machines.
  • Sheet-like structures made from fibers according to the invention have excellent flame resistance with low smoke development, so that they are preferably used as protective clothing, hot gas filters or - for example in the interior of airplanes - as floor coverings, textile wall coverings, curtains or seat cover fabrics can.
