  • an acute threat can be seen in what are known as unconventional explosive devices, which are synonymous with LEDs (“improvised explosive devices”), for example from people who are in military action or counter terrorism, such as soldiers, border guards and police officers.
  • unconventional explosive devices such as LEDs
  • Such explosive devices represent a dangerous tool with a high potential for destruction in warfare or in terrorist actions or the like.
  • Such unconventional explosive devices are also problematic in that they can often be manufactured without great technical effort or without great prior technical knowledge.
  • the materials on which such explosive devices are based, as well as the size and appearance of such explosive devices exhibit a high degree of variability, so that localization and identification are correspondingly difficult.
  • unconventional explosive devices often have a simple structure, they are often associated with a high level of destructive power, since there is an explosive release of primary fragments and secondary fragments (which are caused or released by the impact of the primary fragments or the pressure wave on corresponding objects or the like) so that the total release of fragments is, so to speak, a dangerous and incalculable duplication.
  • the explosion of unconventional explosive devices is accompanied by the creation of a large pressure wave as well as fire and heat, which represent further serious sources of danger.
  • the functionality of unconventional explosive devices is that the explosive device is caused to burst by igniting explosives, accompanied by the explosive release of primary fragments, which propagate at high speed from the explosion site with the simultaneous pressure wave.
  • the pressure wave and the resulting primary fragments can lead to the subsequent release of secondary fragments, often in the form of (micro) particles such as dirt, dust and sand as well as fragments of destroyed objects from the immediate or indirect vicinity of the explosion site of the explosive device.
  • the secondary fragments can also be destroyed by the explosion, for example
  • a so-called primary blast radius which is based directly on the release of primary fragments from the unconventional explosive device

For this reason, too, these materials are only poorly washable or cleanable, which is equally disadvantageous.
  • fibers or yarns based on para-aramids have only a low breaking strength transversely to the longitudinal axis, which is disadvantageous in particular with regard to the processing of these materials into corresponding textile flat materials, in particular in the form of knitted fabrics, since with curvature (e.g. with the loop formation) a yarn or fiber breakage can occur.
