Definitions

  • the invention relates to a refractory staple fiber blend of melamine resin fibers and aramid fibers.
  • Staple fibers from melamine / formaldehyde condensation products are known, e.g. from DE-B 23 64 091, wherein solutions of other fiber-forming polymers can be added to the solution of the melamine resin in the spinning process for producing the melamine resin fibers. They are characterized by incombustibility, flame resistance and high heat resistance. Because of these properties, they are used in the manufacture of refractory textiles. For some applications, however, the tensile strength of the fibers is not sufficient; in other areas of application, the low abrasion resistance proves to be disadvantageous.
  • Fibers made from polycondensation products of iso- or terephthalic acid and phenylenediamine have also been known for a long time. They are also characterized by favorable fire behavior. When processing into yarn using the carding process, however, the low processing speed of the aramid staple fibers proves to be disadvantageous.
  • the invention was therefore based on the object, on the one hand, of improving the properties of melamine resin fibers and, on the other hand, of the properties of aramid fibers.
  • Both types of fibers can contain the usual additives such as fillers, dyes, pigments, metal powder and matting agents.
  • the two types of fibers are usually mixed on conventional fiber mixing apparatuses as described in nonwovens, Georg Thieme Verlag. One starts from staple fibers of a usual length of 1 to 20 cm. These are usually fed to a carding machine via a conveyor and premixed there. The mixing is then generally completed in a carding machine. The wadded web obtained is then usually further processed into yarns or nonwovens, it being possible to use the processes customary in the textile industry.
  • these yarns, nonwovens or woven fabrics can then be further processed into various types of textile or non-textile structures.
  • Mixtures with minor amounts of aramid fibers can be processed as yarn into fabrics, for example for non-combustible curtains or aircraft textiles with very good properties, for example a low smoke gas density. They alone have an increased strength compared to fabrics made of melamine resin fibers.
  • yarns which mainly consist of melamine resin fibers and optionally additionally contain glass or polyacrylonitrile fibers, friction linings, e.g. for couplings.
  • the wadding-like web obtained in the carding process is generally used and needled.
  • the fleece obtained e.g. Filter inserts are produced, the filtration performance compared to nonwovens made from aramid fibers alone being significantly improved.
  • "Fireblocker” can also be produced from the fleece for seats in transport and furniture.
  • heat and sound-insulating fiber mats can be produced from the fleece as described in EP-B 80 655. Such mats show increased strength.
  • Fiber blends that consist predominantly of aramid fibers and e.g. have an aramid fiber content of 95 to 60, preferably 95 to 80% by weight, can be surprisingly spun at a higher speed than pure aramid fibers in yarn production in the carding process.
  • Fabrics and nonwovens can be made from such yarns, e.g. can be used for fireproof suits or for heat blockers.
  • binding fibers can be added to the fiber mixtures and molded parts can be made from them.
  • the binding fibers can consist of condensation resins or thermoplastics.
