Definitions

  • the present invention relates to the technical field of textile sheet materials or textile protective materials which have special protective properties, in particular with regard to the provision of protection against splinters, punctures or cuts.
  • the materials in question can be used in particular in the military or civilian field, both in the field of personal protection and in the field of protection of objects, such as military equipment or the like, whereby, in addition to a protective function against the effects of cutting and stabbing weapons and impact weapons, a protective function against acting (explosive) forces or against ballistic objects or projectiles, in particular in the form of splinters or the like, is also provided or guaranteed.
  • the present invention relates in particular to a textile sheet material (sheet structure) with splinter, puncture or cut protection, which can be used in particular in protective clothing or protective equipment for the military or civilian sector.
  • the present invention also relates to a protective article which is in particular in the form of protective clothing or in the form of protective equipment and which comprises or is formed from the textile sheet material according to the invention.
  • the present invention also relates to the use of the sheet material according to the invention for providing or increasing splinter, puncture or cut protection in protective articles, such as may be in the form of protective clothing or protective equipment.
  • the present invention also relates to a method of providing or increasing splinter, puncture and/or cut protection in the protective articles at issue.
  • unconventional explosive devices are also problematic from the point of view that they can often be manufactured without a great deal of technical effort or 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 location and identification are correspondingly more difficult
  • unconventional explosive devices often have a simple design, they are often accompanied by a great destructive force, since there is an explosive release of primary fragments and secondary fragments caused by them (which are caused or released by the impact of the primary fragments or the pressure wave on corresponding objects or the like), so that with regard to the total fragment release, there is a dangerous and incalculable multiplication, so to speak.
  • the explosion of unconventional explosive devices is accompanied by the generation of a large shock wave as well as fire and heat, which represent further serious sources of danger.
  • the mode of operation of unconventional explosive devices is that the explosive device is detonated by the detonation of explosives, accompanied by the explosive release of primary fragments, which propagate at high speed from the explosion site with the concomitant blast 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 blasting device.
  • the secondary fragments may also originate, for example, from equipment destroyed by the explosion, vehicles (such as vehicle interiors) or the like.
  • equipment used in corresponding military operations or for counter-terrorism such as emergency vehicles, machines, weapons, ammunition, spare parts, electronic objects, accessories, installations, facilities, equipment or the like
  • corresponding primary or secondary fragments can penetrate the outer skin, walls or housing of corresponding objects and thus also act on the interior of the corresponding objects, accompanied by corresponding damage to or destruction of the underlying equipment or the underlying apparatus.
  • such objects can also be damaged or destroyed accordingly as a result of the use of, for example, cutting or stabbing weapons.
  • the protective materials known in the prior art also sometimes have the disadvantage that they are often not sufficiently flexible in terms of their material properties, which impairs their individual adaptability to the structures to be protected, their further processing and their wearing comfort, for example in the case of use as protective clothing.
  • the protective materials known in the prior art do not always exhibit a desired durability with respect to ballistic stability.
  • the haptic properties are not always optimal.
  • para-aramids Although such systems based on para-aramid exhibit a certain strength, impact strength and elongation at break and are thus fundamentally suitable as a fragmentation protection material, a central disadvantage of para-aramids is that they are neither UV-stable nor moisture-stable, so that corresponding materials based on para-aramids lose their strength properties and thus their ballistic protection function when exposed to UV-radiation or moisture, such as body perspiration or rain or washing water. For this reason too, these materials have only limited washing and cleaning properties, which is equally disadvantageous.
  • fibers or yarns based on para-aramids have only a low breaking strength transverse to the longitudinal axis, which is disadvantageous in particular with regard to the processing of these materials into corresponding textile sheet materials, in particular in the form of knitted fabrics, since yarn or fiber breakage can occur in the event of bending (e.g. in the formation of stitches).
  • the state of the art sometimes provides for the material based on para-aramids to be provided with a water-repellent finish or to be shrink-wrapped in films in order to counteract the degenerative process of loss of stability, in particular due to moisture or UV radiation.
  • the wearing comfort of the resulting materials is impaired, since the transport of moisture is reduced or prevented when worn and the air permeability of the material is also adversely affected.
  • the underlying materials are only suitable to a limited extent for use in protective form of outer clothing or outer underwear, which is worn in particular as the outermost layer and is thus exposed to direct sunlight.
  • the drying or storage of the materials under sunlight with corresponding UV exposure is also problematic.
  • DE 30 34 547 C2 relates to a garment having at least one puncture-resistant surface element comprising a plurality of three-dimensionally shaped and mutually consolidated layers of textile aramid fiber surfaces, the surface element being consolidated by stitching in a preselected shape adapted to the body shape of the wearer.
  • WO 99/37969 A1 as well as DE 198 02 242 A1 or EP 1 058 808 A1 or U.S. Pat. No. 6,656,570 B1, which belong to the same patent family, relate to a protective clothing for protection against stabbing injuries, which is intended to provide a certain degree of protection against needle-like stabbing devices, the protective clothing comprising a plurality of layers of sheet-like structures made of break-resistant materials, more than one of the layers being coated with a hard material layer. This is based on the use of aramid fabrics to form the layers.
  • EP 1 229 298 A1 relates to a protective element which can be used to protect equipment or objects and which has a cover-like structure with solid fibers, the protective element having cavities or chambers which are filled with at least one hollow body.
  • the underlying fibers the use of aramid fibers is considered to be decisive.
  • the underlying yarns do not always have optimal processing characteristics, in particular with regard to their stiffness and sliding properties (which makes their processing into textiles more difficult). Moreover, even such yarns can still be optimized in terms of their stability. Moreover, excessive stiffness due to limited flexibility and pliability also leads to less than optimal wearing properties when used for protective clothing and to limited adaptability of the materials when used as protective covers or the like for devices or equipment.
  • the materials mentioned in the prior art or concepts provided in this respect do not always have optimum stability properties with regard to guaranteeing a certain protective function against ballistic force effects, in particular with regard to providing a certain splinter protection, and this also with regard to providing a permanent ballistic resistance.
  • the materials or concepts known in the prior art are not always accompanied by optimum application and processing properties, whereby, moreover, in particular with regard to use as protective clothing, optimum wearing properties are not always present and, with regard to use as protective equipment for objects, optimum adaptation properties to the object to be protected are not always present.
  • one particular task of the present invention is to provide a protective material which can be used as protective clothing and also as protective equipment or material (for example for protecting objects or equipment material or the like) for the military or civilian sector and which has an improved ballistic protective function compared with the prior art, in particular with respect to fragments released by detonation or explosion, it also being intended to provide stab-protection and cut-protection properties.
  • the protective material provided according to the invention is also to have a high resistance to moisture and UV-radiation, while at the same time having a high protective function.
  • one task of the present invention is in particular to provide a special protective material which has a high surface stability and durability, whereby the protective material should at the same time be universally usable or have an individual adaptability with regard to the underlying purpose, for example as protective clothing or as protective equipment for equipment or objects or the like, or can be tailored for the respective purpose.
  • a high overall splinter protection function as well as corresponding cut or stab protection properties are to be provided at the same time.
  • a correspondingly high level of wearer comfort should also be guaranteed.
  • Another object of the present invention is to provide a corresponding protective material which has improved processability into corresponding protective clothing or protective equipment.
  • the present invention thus proposes—in accordance with a first aspect of the present invention—the textile sheet material or sheet structure with splinter, puncture and/or cut protection properties, preferably with splinter protection properties, in particular for use in protective clothing or protective equipment for the military and/or civilian sector, initially claimed and then in further patent claims (secondary claims) which are independent in this respect; in each case further advantageous further developments and embodiments of this aspect of the invention are the subject of the corresponding subclaims relating to the textile sheet material.

  • processing properties such as improved processing, for example, into protective clothing or protective equipment
  • application properties such as improved wearing comfort in the case of use as protective clothing.

  • the use of a very special UHMW-PE multifilament yarn leads to improved splinter, puncture or cut protection, preferably improved splinter protection, of the resulting textile sheet material, since the special multifilament yarn itself has improved stability properties.
  • the improved properties of the textile sheet material can also be attributed decisively to the special UHMW-PE multifilament yarn with its special formation on the basis of a multiplicity of UHMW-PE individual filaments, which are combined or twisted together in the multifilament yarn, for example by means of twists, and form the multifilament yarn as such.
