Definitions

  • the invention relates to protective clothing, in particular antiballistic protective clothing for women, consisting of one or more protective layers arranged one above the other and possibly connected, these protective layers of textile fabrics made of antiballistically effective fibers.
  • Bullet and splinter-resistant protective clothing especially bullet and splinter-resistant vests, belong more recently in many countries as standard equipment for the military, police and other security forces. There in these areas, women are increasingly used, it is necessary that this protective clothing to the female Body shape is adjusted.
  • the conventional protective clothing designed for men to wear is for Women are problematic and only possible with a considerable loss in comfort. Especially with one Use, which is associated with high physical stress, proves this low wearing comfort for men developed protective vests extremely hindering.
  • US 4,457,985 discloses antiballistic articles containing a network of polyolefin fibers.
  • textile fabrics made of polyolefin fibers are also disclosed, with several being under pressure and heat without a matrix material being bonded to one another.
  • protective clothing is described in US Pat. No. 4,578,821, in which a special material is applied to a carrier material Breast shaping for women can be put on.
  • a conventional vest for example, can be used as the carrier material Find use.
  • no solution is offered that offers sufficient comfort because the overall protective clothing is not adequately adapted to the female body shape.
  • the task was to develop protective clothing, especially antiballistic protective clothing for women, which is well adapted to the body shape and thus a high level of comfort without loss of protection offers and which can also be produced very inexpensively.
  • this object can be achieved in a particularly advantageous manner, if the deformations necessary for adaptation to the body shapes, such as the shaping of the bust part in protective clothing for women, using a molding process, and the protective layers are formed on individual layers without the use of a resin.
  • protective clothing especially antiballistic protective clothing for women at low cost without loss
  • To be able to produce a protective effect is the task of improving the wearing comfort by the Protective clothing well adapted to body shapes, especially the bust part which is well adapted to female body shapes, solved in a particularly advantageous manner.
  • aramid fibers which are also known as aromatic polyamide fibers, are often used in the protective layers.
  • Such fibers are commercially available, for example, under the brand name Twaron R.
  • Aramid fibers are polyamide fibers that are at least partially made up of aromatic compounds. When the polyamides are formed, for example by polycondensation of an aromatic amine with an aromatic acid or its chlorides, both the acid component and the amine component can consist wholly or partly of aromatic compounds.
  • Aramid fibers are fibers within the meaning of the invention, the main part of which is composed of aromatic compounds which form amides.
  • polyolefin fibers are also used for antiballistic protective clothing, especially after the gel spinning process manufactured polyethylene fibers, use. These are also for the production of the invention antiballistic protective clothing suitable. The same applies to other antiballistically active fibers, such as so-called antiballistic nylon.
  • Antiballistically effective materials are to be understood as those that prevent the penetration of projectiles, fragments etc. oppose resistance and slow down their speed when hitting these materials.
  • Fabrics made from aramid fibers are often used to form the antiballistically effective protective layers. This Fibers are preferred as filament yarns to make fabrics, but the use of spun yarns is also possible. Filament yarns, however, achieve higher strength and a better antiballistic effect.
  • Protective layers in antiballistically effective clothing are understood to mean the layers that are antiballistically effective Contain materials in the above sense. These protective layers are very often antiballistic Clothing around aramid fiber fabrics.
  • Antiballistic protective clothing is therefore clothing that effectively protects the body against the penetration of projectiles, fragments, fragments of explosive devices, etc.
  • filament yarns are used for the production of fabrics, these come in titers of 400 - 3400 dtex for use.
  • the filament titer is preferably less than 1.7 dtex.
  • the yarns can be processed into fabrics on all machines commonly used in weaving technology. Fabric production in plain weave is preferred, but other weaves, such as a Panama weave, are also possible.
  • the thread numbers to be used depend on the titer of the yarn and the desired fabric density.
  • the following information for thread counts for the production of fabrics in plain weave from aramid fibers for antiballistic protective layers are to be regarded as examples: yarn count Number of threads per 10 cm fabric weight dtex in chain u.
  • the invention is not intended to be limited to the use of fabrics for the protective layers.
  • fabrics for the protective layers In the same Other flat structures such as foils, laid scrims, nonwovens or knitted fabrics can also be used Find.
  • textile fabric is used here for fabrics made from fiber materials. These include fabrics, knitwear, nonwovens, laid scrims, etc. Tissues are made for the Manufacture of protective clothing according to the invention preferred.
  • a bust is formed using a molding process. Molding process and the corresponding machines are known in the bodice industry.
  • One for the production of protective layers for antiballistically effective protective clothing A particularly suitable molding process is initially filed with the German Patent Office Patent application P 44 23 194.6 described. The process described there looks for fabrics made of aramids Temperatures of 180 - 300 ° C at a machine pressure of 4 - 8 bar (400 - 800 kPa).
  • thermoplastic are particularly suitable for molding Materials.
  • Aramid fibers which are preferred for antiballistic protective clothing, are not among them Thermoplastics, since they have no defined melting and softening point and before melting decompose. It was therefore surprising that it was possible to use a molding process to deform flat materials to make from these fibers and in this way to create a way out of such materials Protective clothing to be produced in a particularly favorable manner to the body shapes, especially to the female ones Body shapes to be able to adapt.
  • the antiballistic protective layers show after the shaping of a bust part by means of a molding process deformed areas do not lose antiballistic effectiveness, such as those listed below Show bullet attempts.
  • the material to be tested was bombarded in several layers one above the other.
  • the number of layers was chosen so that it corresponds to the conditions as they exist in the protective vest.
  • the bombardment was carried out with 9 mm para-ammunition from a distance of 10 m at a bombardment angle of 90 °.
  • the antiballistic effect was checked once by detecting a possible bullet to others by examining the change in a plasticine mass behind the material to be bombarded. For this purpose, the depth of impression of the projectile in the plasticine mass was determined, which is an approximate measure for the Energy impact of a projectile on the human body should be determined in the event of a bombardment.
  • the police departments use up to 44 mm as the depth of penetration into the plasticine mass authorized.
  • the anti-ballistic protective layers deformed by molding are preferred for bulletproof vests for women Use. For this purpose, between 20 and 30 of these layers are placed one on top of the other so that the molded bust parts lie exactly on top of each other. Such a vest often consists of 28 protective layers. After the Introducing the formations consolidated with a cross stitching, each of the two crosswise running seams about 10 cm in length. This cross stitching is below the molded bust appropriate. A sewing thread, for example made of aramid fiber, is used for quilting. The antiballistic so formed Package is then used to manufacture a bulletproof vest in a prefabricated envelope made of PVC film also welded in by molded breast part.
  • the deformation of the PVC envelope takes place in such a way that double-layered, already welded on one edge and still open on three edges by means of molding the bust part is shaped according to the shape of the antiballistic protective layers.
  • This envelope which then The antiballistic package is inserted both on the front and on the back and the still open edges are welded watertight. Then it is welded into PVC film Package, for example, in a dyed or printed cotton or cotton-polyester fabric that matches the formations of the antiballistic package is introduced.
  • the antiballistic package for example when cleaning is necessary, the package is not in the outer fabric fully sewn, but there is an opening and removal option by means of a zipper or Velcro created.
  • the antiballistic protection layers are contained in the clothing in the form of the so-called antiballistic package.
  • This package is covered on both sides by cover layers, which can be of different types.
  • Under Cover layers are layers of textile or non-textile fabrics that are below or above the package of protective layers are arranged to understand.
  • Cover layers are also PVC films, for example, which are used to weld in the antiballistic protective layers Find.
  • the invention is not intended to be limited to the use of PVC films, including others suitable materials can be used in the same way. If PVC foils are used, this is done shaping the bust part by means of a molding process at temperatures of 60-100 ° C., preferably at 70 - 90 ° C.
  • the machine pressure is 2 - 5 bar (200 - 500 kPa), preferably 3 - 4 bar (300 - 400 kPa).
  • splinter protection vests for women, which are used especially in the military area, For example, 14 layers are placed on top of each other so that the molded bust parts are exactly on top of each other. The layers are sewn together at the edges.
  • the antiballistic package thus formed is then converted into a Prefabricated cover, for example made of polyester fabric coated on both sides with neoprene, also with Molded molded bust part sewn or welded.
  • the deformation of the coated polyester fabric takes place in such a way that in a double-layer, already sewn or welded on one edge and on three edges still open coated polyester fabric by molding the bust part according to the shape of the antiballistic Layers is formed.
  • coated polyester fabrics In addition to coated polyester fabrics, other coated materials can also be used as the covering material Find textile fabrics.

  • the antiballistic Package inserted and the edges that are still open are sewn or welded.
  • the in the cover is made of coated polyester fabric or another coated textile fabric or sewn package, for example in a dyed or printed cotton or cotton-polyester fabric, which is adapted to the shape of the antiballistic package.
  • the protective clothing according to the invention provides for female security forces by a in the protective and cover layers the molded bust part is extremely comfortable and does not restrict the freedom of movement. With the protective clothing according to the invention, a significant advance in the production of Protective clothing, especially in the manufacture of protective vests for female security forces, without sacrificing Protection effectiveness achieved.
  • a woven fabric was made from a filament yarn made of aramid fibers with a titer of 930 dtex in plain weave. The thread counts were 10.7 / cm in the warp and 10.5 / cm in the weft. The fabric obtained had a weight of 202 g / m 2 and a thickness of 0.30 mm. Cuts for protective vests were cut out of this fabric. A bust part was individually formed on these blanks using the molding process described in patent application P 44 23194.6, which was filed with the German Patent Office at the same time. A total of 28 layers of these blanks were put together to form a package and welded into a PVC sleeve, on which a bust part had also previously been formed by deep drawing.
