Definitions

  • the invention relates to a breathable material for Protective clothing for shielding against electromagnetic High frequency fields and / or for camouflage against thermal imaging devices.
  • the material mentioned at the outset is intended to prevent that such high-frequency and high-energy radiation Cause damage to the human organism.
  • the effect of high-frequency electromagnetic Waves on the cell structure is essentially a heat effect, also called thermal effect. Now becomes one Exposure to heat exceeded by radiation human body usually through a secretion can regulate from sweat, it can be harmful Influences of heat due to the electromagnetic waves the organism come.
  • Ionizing rays in a frequency spectrum above the light range are so high in energy that they can cause damage to the molecules of the cell tissue.
  • the harmful radiation density is already 5 mW / cm 2 . It was found that a power flux density of 10 mW / cm 2 when absorbed in humans already results in a heating power of 1 W / kg comparable to the basal metabolic rate.
  • Backing materials in suit form which as textile net with silver and a subsequent rubber coating are trained.
  • Networks are also included stored metal foils known.
  • metal fibers or metal wires e.g. VA short fibers, Copper filaments, tinned copper threads, covered with copper Polyester filament yarns and the like, sufficient Obtain shielding attenuation values. Because of the vulnerability the metal filaments, especially against breakage, or working out the metal fibers during the practical Such carrier materials are used, however only suitable to a limited extent.
  • DE-A-3445997 discloses a metal coated Fiber object, consisting of a fibrous base material, a basic covering made of synthetic resin, a metal coating applied to the base coat and a synthetic resin cover. Also from this document discloses a method in which the metal coating in an inert gas atmosphere and at a electrical voltage occurs.
  • the disadvantage of this invention lies in the complicated structure the coating with an additional base coat made of synthetic resin and the necessary pretreatment of the fibers with a phosphorus compound.
  • the spray coating applied to apply the metal layer in an inert gas atmosphere and with an electrical one Tension is a very elaborate technique with very high manufacturing costs.
  • a camouflage in front of thermal imaging devices is by a Protective clothing made with this solution is not possible. Furthermore, this solution sees before the metal coating treatment of the individual fibers with alkali before to get an irregular surface, however enormous manufacturing costs. Through the coating the fabric with a metal layer is a protection given against electromagnetic waves, the top layer made of synthetic resin allows the breathability of the Materials not too.
  • the present invention is therefore based on the object creating breathable material for protective clothing, that not only ensures high shielding, but also good practical and for has the properties required for a work assignment, such as. good abrasion resistance, washability and breathability or air permeability and through that there is no build-up of body heat (also no heat absorption through the tissue).
  • the polymer layer also makes a good one Temperature resistance and high cold flexibility reached.
  • the carrier material or the base material receives a good one Resistant to light, weather, aging and hydrolysis.
  • the production of the base material according to the invention or Backing material can advantageously be made that on polyamide fabric that already has a silver layer has been fully metallized in one Application procedure the crosslinking polymer polydimethylsiloxane polyacrylate is applied.
  • the base material for the protective suit is polyamide fibers or polyamide yarns 1, which are also known under the trademark nylon, as 6.6 ripstop fabric or as parachute silk.
  • Such a fabric is coated with 35% by weight of a pure silver layer 2 over the entire surface and thus metallized, ie each individual fiber of the fabric has a complete silver coating with very good adhesion.
  • the fabric created in this way can have a weight class of approximately 50 g / m 2 .
  • a crosslinking polydimethylsiloxane polyacrylate is applied to this fabric, which can be designed as a woven fabric, as a nonwoven fabric or a knitted fabric, per application, whereby the silver layer 2 is created by the resulting layer Polymer layer 3 is sealed.
  • Foularding is a kind of immersion bath with rollers over which the yarns or the fabric, braid, Fleece or the like are performed.
  • the fabric After a drying process, the fabric becomes brief heated to temperatures of 160 to 180 ° C to crosslink to reach.
  • the pore size of the tissue is chosen so that even after coating with the polymer layer 3 enough space or pores between the individual Fibers or yarns remain, thus breathability preserved.
  • the carrier material produced in this way is now so made up to a protective suit that a perfect Shielding and, if desired, camouflage of human beings achieved through a whole body assembly becomes.
  • a one-piece protective suit 4 in Provide overall form that fits in the appropriate places a nickel-plated zipper 5 is provided.
  • a nickel-plated zipper 5 is provided.
  • a nickel-plated zipper 5 is provided.
  • Protective suit 4 may not be used to maintain the shielding have wide sleeve and pants ends so that the Radiation cannot penetrate. For this reason one ends the sleeves and pants with zippers or Keep the elastic bands tight.
  • a protective helmet is located above the protective suit 4 in the head area or to provide a hood 9 made of the same Material consists of the protective suit 4.
  • the protective helmet 9 or the hood is closed by a face shield 10 close and in a protective suit with a large overlap integrate inside.
  • a face protection or field of view 10 is a with metal sheathed mesh fabric or bars 11 used.
  • the protective suit 4 is used in the civil sector in general as a base suit to protect against electromagnetic Fields in the MHz / GHz range are carried over which a normal work suit is pulled so the protective suit 4 against damage, reducing the shielding effect would be compromised.
  • the protective suit 4 could also through an appropriate combination with a conventional one Work suit or an externally attached material also designed in one piece as a complete work suit will.
  • the suit When using the protective suit 4 in the military Area, where a function in the thermal image in the sense of a If camouflage is desired, the suit must be worn as an upper suit be used to camouflage thermal imaging devices produce. In this case it is different from one Work deployment in the civilian area is not absolutely necessary to protect the protective suit from damage. This means that in this case, in addition to protection against electromagnetic fields, e.g. in the immediate area of radar systems, there is also camouflage.
  • the protective suit can also be used as pure camouflage suit for people, even if no health Problems caused by electromagnetic fields occur.
  • a protective suit in the specified composition excellent for camouflaging people in the thermal imaging area suitable is.
  • the shielding attenuation for electromagnetic radiation is in effective in a frequency range from 100 MHz to 100 GHz, the minimum attenuation is 20 dB.
  • the suit For camouflage against thermal imaging devices in the thermal imaging range of 10 12 to 10 15 Hz, for example, the suit must be worn as an upper suit.
  • the suit For the required camouflage in the optical and near infrared, only 50% of the area with color green and black is applied as camouflage on the outside of the protective suit 4. The remaining 50% of the area remains from the urban, generally brown, inherent color of the fabric.
