Definitions

  • This invention relates to protective equipment for soldiers involved in chemical or biological warfare.
  • toxic airborne chemical agents have been used by soldiers on one side to disable or kill enemy soldiers on the other side.
  • toxic and/or lethal chemical agents include mustard gas - either in the form of "liquid” mustard (HD) or of thickened mustard/glycerine mix -, nerve gaz such as soma (GD), tabun, sarin, VX and lewisite.
  • Toxic biological air borne agents have also been reportedly used in warfare, for example, anthrax.
  • airborne toxic agents such as chemical poisons or biological toxins
  • they rely on the wind as their vector of transportation, so that after their release by soldiers from one side, if the wind unexpectedly turns back afterwards, these poisons are carried back to their original source and these soldiers can then become poisoned by their own chemical poisons or biological toxins.
  • air borne toxic agents can be released anytime during day or night, even when the soldiers are sleeping in their tents.
  • moisture vapour permeable (breathable) fabric sheets cannot boast resistance to HD and GD since they are breathable.
  • Tent fabrics cannot provide specific protection against HD and GD.
  • the other chemical resistant material for garments may protect against industrial chemicals that most well engineered fabric can resist to, but HD and GD are not conventional industrial chemicals.
  • the gist of the present invention is to improve upon chemical and biological agents resistant existing tentage material.

Abstract

L"invention concerne un matériau de tente convenant pour une utilisation militaire (guerre ou terrorisme), et offrant une résistance chimique et/ou une protection contre les attaques biologique empêchant la pénétration d"un agent chimique toxique. Ce matériau de tente se compose d"un textile de polyester sur lequel est appliquée une pellicule, d"un revêtement interne sur chaque face et d"un revêtement externe sur chaque face. Ce matériau peut être soudé et peut résister à des conditions extrêmement difficiles telles que celles rencontrées dans les utilisations militaires de la même manière qu"un matériau de tente conventionnel, et offre une solidité équivalente. La membrane décrite offre une protection contre les agents chimiques et contre les biotoxines plusieurs fois supérieure à celle du caoutchouc butyle.
