Definitions

  • the present invention relates to the technical field of textile planar 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 civil sector, both in the field of personal protection and in the field of protecting objects such as military equipment or the like, in addition to a protective function against the effects of cutting and thrusting weapons as well as thrust weapons, a protective function against acting (explosion) forces or against ballistic objects or projectiles, in particular in the form of splinters or the like, is provided or guaranteed.
  • the present invention relates to a protective object which is designed in the form of protective clothing and which has or is formed from a textile planar material (planar structure) with splinter, puncture or cut protection as described here.
  • the present invention according to claim 13 also relates to the use of the sheet material described here to provide or increase protection against splinters, punctures or cuts in protective objects, such as is present in the form of protective clothing.
  • Such an impact can, for example, not only be caused by projectiles from firearms or the like, but also by the impact or explosion of explosive devices and with the associated release of fragments [both on the basis of primary fragments coming directly from the explosive device and those released in the subsequent process of the explosion or secondary fragments (which can be caused by the impact or impact of primary fragments or pressure waves associated with the explosion on other objects)] and also as a result of the force exerted by various objects, such as flying debris or the like, caused or caused by this.
  • Such an effect of force or violence is accompanied by an even considerable risk of injury for the persons affected.
  • Improvised Explosive Devices are an acute threat, for example to persons deployed in the military or in counter-terrorism, such as soldiers, border guards and police officers .
  • 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 because they can often be produced 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 level of variability, so that location and identification are correspondingly more difficult.
  • unconventional explosive devices often have a simple structure, they are often associated with great destructive power, since there is an explosive release of primary fragments and secondary fragments caused by this (which are caused or released by the impact of the primary fragments or the pressure wave on corresponding objects or the like be) comes, so that with regard to the total release of fragments there is, so to speak, a dangerous and unpredictable duplication.
  • the explosion of unconventional explosive devices proceeds with the emergence of a large one pressure wave as well as fire and heat, which represent further serious sources of danger.
  • the operation of unconventional explosive devices is that the explosive device is ruptured by detonating explosives, accompanied by the explosive release of primary fragments, which propagate at high speed from the explosion site with the concomitant pressure wave.
  • the pressure wave and the resulting primary fragments can lead to the subsequent release of secondary fragments, often in the form of (small) 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 originate, for example, from items of equipment, vehicles (such as vehicle interiors) or the like destroyed by the explosion.
  • primary blast radius which is aimed directly at the release of primary fragments from the unconventional explosive device
  • secondary explosion radius which concerns the subsequent release of secondary fragments as a result of the blast and the resulting primary fragments, starting from the explosion site of an unconventional explosive device.
  • equipment or equipment used in corresponding military operations or for countering terrorism such as emergency vehicles, machines, weapons, ammunition, spare parts, electronic objects, accessories, systems, facilities, equipment or the like
  • conventional explosive devices with the associated release of fragments
  • Corresponding primary or secondary splinters can, for example, penetrate the outer skin, walls or the housing of corresponding objects and thus also affect the interior of the corresponding objects, accompanied by corresponding damage or destruction of the underlying equipment or the underlying equipment.
  • objects of this type can also be correspondingly damaged or destroyed as a result of the use of cutting or thrusting weapons, for example.
  • the protective materials known in the prior art also sometimes have the disadvantage that their material properties are often not sufficiently flexible, which impairs their individual adaptability to structures to be protected, their further processing and their wearing comfort, for example when used as protective clothing.
  • the protective materials known in the prior art do not always have the desired durability in terms of ballistic stability.
  • the haptic properties are not always optimal.
  • para-aramids Although such systems based on para-aramid have a certain strength, impact strength and elongation at break and are therefore basically suitable as splinter protection material, a key disadvantage of para-aramids is that they are neither UV-stable nor moisture-stable, see above that corresponding materials based on para-aramids lose their strength properties and thus their ballistic protective function when exposed to UV radiation or moisture, such as body sweat or rain or washing water. For this reason, too, these materials have only a low washing or cleaning ability, which is equally disadvantageous.
  • fibers or yarns based on para-aramids have only a low breaking strength transversely to the longitudinal axis, which is particularly disadvantageous with regard to the processing of these materials into corresponding textile sheet materials, especially in the form of knitted fabrics, since with curvature (e.g. with stitch formation) yarn or fiber breakage can occur.
  • the basic materials are only suitable to a limited extent for use in protective clothing in the form of outerwear or outerwear, which is worn in particular as the outermost layer and is therefore exposed to direct solar radiation. In this context, drying or storing the materials under solar radiation with corresponding UV exposure is also problematic.
  • the DE 30 34 547 C2 relates to an item of clothing with at least one puncture-resistant planar element made of a plurality of three-dimensionally shaped layers of textile aramid fiber surfaces that are bonded together, the planar element being bonded in a preselected shape adapted to the body shape of the wearer by quilting.

The focus here is on the use of aramid fabrics to form the layers.
  • the EP 1 229 298 A1 a protective element which can be used to protect equipment or objects and which has a blanket-like structure with solid fibers, the protective element having cavities or chambers which are filled with at least one hollow body.

  • the underlying yarns do not always have optimal processing properties, especially with regard to their stiffness and sliding properties (which processing into textiles is more difficult).
  • such yarns can still be optimized with regard to their stability.
  • excessive rigidity due to the limited flexibility and pliability also leads to less than optimal wearing properties when used for protective clothing and to a limited adaptability of the materials when used as protective covers or the like for devices or pieces of equipment.
  • the materials cited in the prior art or concepts provided in this regard do not always have optimal stability properties with regard to ensuring a certain protective function against ballistic forces, in particular with regard to providing a certain splinter protection in terms of providing sustained ballistic resistance.
  • the materials or concepts known in the prior art do not always go hand in hand with optimal application and processing properties, and in addition, especially with regard to use as protective clothing, there are not always optimal wearing properties and with regard to use as protective equipment for objects optimal adaptation properties to the object to be protected are present.
  • an object of the present invention is to be seen as providing a protective material that can be used as protective clothing and also as protective equipment or material (e.g. to protect objects or equipment material or the like) for military or civilian Area can be used and which has an improved ballistic protective function compared to the prior art, in particular against splinters released by detonation or explosion, whereby puncture and cut protection properties should also be provided.

  • a high splinter protection function and at the same time corresponding cut and puncture protection properties should be provided.
  • a correspondingly high level of wearing comfort should also be ensured.
  • a further object of the present invention is to provide a corresponding protective material which has improved processability to form corresponding protective clothing or protective equipment.
  • the present invention thus proposes - according to a first aspect of the present invention - the protective article according to the invention, which is in the form of protective clothing, with splinter, puncture or cut protection properties, preferably with splinter protection properties for military and/or civil sphere according to the patent claim which is independent in this respect and relates to the subject matter of protection; further advantageous developments and refinements of this aspect of the invention are the subject matter of the corresponding dependent claims relating to the protected subject matter according to the invention.
  • the subject of the present invention - according to a second aspect of the present invention - is also the use of the planar material according to the invention to provide or increase protection against splinter, punctures or cuts, preferably splinter protection, for protective objects in the form of protective clothing according to the relevant independent claim to use.
  • the textile planar material described here or which can be used according to the invention is in particular a planar and/or two-dimensional textile material.

  • processing properties such as an improved Processing, for example, into protective clothing
  • application properties such as improved comfort when used as protective clothing.
  • the production of the textile sheet material as such is improved, in particular since the special UHMW-PE multifilament yarn has improved bending and flexibility properties, which is beneficial, for example, for the preferred design of the material as a knitted fabric, as detailed below .
  • the flexibility or flexibility of the resulting textile sheet material is also improved at the same time, which is equally associated with positive effects on wearing comfort when used as protective clothing and the adaptability to objects to be protected.
  • the use of a very special UHMW-PE multifilament yarn leads to improved splinter, puncture and 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 are also largely due to the special UHMW-PE multifilament yarn with its special design based on a large number UHMW-PE individual filaments back, which in the multifilament yarn, for example, by means Twisting are summarized or twisted together and form the multifilament yarn as such.
  • the UHMW-PE multifilament yarn is formed or consists of individual UHMW-PE filaments, which are combined by twisting (twisting or twisting) to form the UHMW-PE multifilament yarn (single yarn).
  • the stability and flexibility or pliability properties of the resulting multifilament yarn are primarily improved in that the UHMW-PE individual filaments are present in a twisted form, so to speak, as a result of being twisted or twisted together in the multifilament yarn.
  • This increases the flexibility of the multifilament yarn itself, since the mobility of the individual filaments in the multifilament yarn is improved overall.
  • the stability is increased, since the kinetic energy introduced can be better distributed and dissipated, and the twisted arrangement also results in mutual reinforcement of the individual filaments.
  • the improved flexibility of the multifilament yarn as a result of the twisted arrangement of the individual filaments also leads to advantages with regard to the processing of the underlying multifilament yarn into the textile planar material, after which the planar material or the yarn system is preferably formed as a knitted fabric. Because in this regard, the situation is such that, particularly with regard to the underlying stitches, which represent a central element of a knitted fabric, high bends or small curve radii are required in relation to the multifilament yarn, which due to the high pliability or flexibility of the multifilament yarn used according to the invention in can be realized in a correspondingly simplified or improved manner. In this context, for example, particularly small curve radii can be realized when laying the yarn, which also leads to a high yarn density or to a high surface coverage of the textile planar material with the multifilament yarn, again accompanied by improved ballistic stability.
  • the multifilament yarn used according to the invention retains the above-mentioned high pliability or flexibility even with relatively high titres or counts (which lead to an additional improvement in the stability properties), so that even for relatively heavy yarns or For yarns with a relatively large diameter, there are correspondingly good processing properties and improved product properties with regard to the resulting textile sheet material.
  • the textile planar material described here in addition to providing excellent protection against splinter, punctures and/or cuts, preferably splinter protection, also has shot and/or impact protection. Consequently, the textile planar material also has a good protective function, for example against projectiles coming directly from firearms or the like or against the effects of blunt weapons.
  • a special multifilament yarn in the form of UHMW-PE or individual filaments in the form of UHMW-PE is used in the context of the present invention to form a multifilament yarn.
  • the applicant has equally surprisingly found that the use of such a special material is therefore also particularly suitable for forming the textile sheet material described here, that polyethylene with an ultra-high molecular weight in the form of multifilament yarns has a very high tensile strength and a high Tensile strength, high breaking strength and flexural strength and a very high modulus of elasticity.
  • UHMW-PE is moisture and UV resistant, which means that the sheet materials provided according to the invention have a high resistance to water (washing resistance), along with a high durability of the ballistic protective function, especially in direct sunlight, as mentioned above .
  • the UHMW-PE has very good chemical resistance and outstanding bacterial resistance.
