Definitions

  • the present invention relates to flame retardant fabrics based on of melamine resin fibers, fire protection ceilings made from them and fire protective clothing and their use for extinguishing Fires and to protect people and objects from fire, Combustion products and / or extinguishing agents.
  • fire blankets which are often called "fire blankets” are usually used to combat smaller ones Fires, extinguishing the flames by suffocating them.
  • fire protection ceilings which are primarily not used as fire blankets, but in particular should be suitable for people or objects from fire, heat, combustion products such as soot, or extinguishing agents to protect.
  • Such blankets would be of particular value, for example, in Churches and museums, which often have a variety of irreplaceable works of art store which are insufficient against fire and in the event of a fire, against the immediate consequences of the fire, such as Protected against heat and soot, as well as against the consequences of extinguishing measures are.
  • WO 95/14126 fiber mixtures are known, the melamine resin fibers and contain aramid fibers. From these fiber blends flame-retardant fabrics can be produced.
