Definitions

  • the present invention relates to a ready-to- wear protective clothing against toxic or noxious compounds and viruses and to a stratified material suitable for said clothing. It finds its main application in chemical and pharmaceutical industries, particularly in biological laboratories specialized in the production of vaccines .
  • the protective clothing are made of a stratified protective material which consists of different layers. A protection may only be obtained if at least one of the layers is completely impermeable to gases and liquids and if this layer can offer chemical resistance over a longer period of time against the penetrating attacking compounds.
  • the invention relates to a protective suit in one piece, comprising a protective cap, a protective apron, gloves and coat for workers who are exposed to hazardous environments.
  • the invention concerns also a method of operation for the preparation of a stratified protective material against toxic compounds, especially chemical, microbiological and virological.
  • the material consists of a layer of textile fabric such as treated cotton and analogous material, an intermediate layer of mineral fibres and/or an absorbing carbon layer, a final layer of insulating and permeable foam plastic the cells of which are provided with an absorbing carbon layer. Quite often these suits have little effect against certain penetrating industrial pharmaceutical and war gases, to such an extent that the user no longer is protected, not even for a short time.
  • the present invention intends to correct these drawbacks and introduces a stratified protective material for producing ready-to-wear protective clothing against toxic or harmful compounds, offering virtually complete protection.
  • the protective material consist of several layers, such as an organic chemical layer or a layer of analogous fabrics and is distinguished because one of these layers is an aluminium layer, optionally finished with a layer of organic chemicals.
  • the ready-to-wear protective clothing includes an autonomous gasmask comprising an oxygen-source and a cartridge comprising a CO 2 - absorber of the exhaled carbon dioxide. It comprises usefully warning systems controlling the oxygen-supply and the carbon dioxide.
  • the CO 2 -absorber is preferably lime.
  • the aluminium layer consists of an extremely thin layer of aluminium foil.
  • the aluminium layer has a minimum thickness of about 8 micron.
  • the aluminium foil is glued onto a piece of fabric, or organic polymers.
  • the aluminium layer gives us a number of advantages, such as in the area of permeability to gas, chemical, microbiological or virological contamination.
  • the aluminium layer offers excellent vapour inhibiting features and possesses the property of reflecting warmth
  • the invention also concerns a method to produce the above described protective material.
  • the fabric layer is preferably heated to approximately 45°C together with the aluminium foil; after that both materials are glued together by means of water polyvinyl alcohol adhesive or analogous .
  • a thin aluminium layer 2 of minimum about 8 micron is applied, by gluing an aluminium foil onto it by means of a water polyvinyl alcohol adhesive seal 4.
  • the aluminium foil can already be adhered in advance to an existing plastic film 3 polyethylene ( ⁇ 70 micron).
  • aluminium protective material is suitable for the protection against such radioactive isotopes.
  • an aluminium layer offers the best protection, among other things : against isocyanates, extremely aggressive substances such as mustard gas; extremely penetrating substances, such as cyanides, mycotoxins, phosphorus, organic phosphoric compounds, fire bombs, lighting bombs, polymers, pyrolysis products, ⁇ - and ⁇ -rays, radioactive isotopes and radiation, etc.
  • aluminium suits produced with a protective material which consists of an aluminium layer 2, finished with organic chemical layers 1 and 3 or analogous compounds, offer almost complete protection. This depends among other things of the acidity of the aggressive substances.
  • Such material as described above is impermeable to any kind of low energetic particles. As such the material is impermeable to bacteria, spores and viruses.

Abstract

L'invention concerne des vêtements protecteurs prêts à porter assurant une bonne protection contre les composés toxiques et dangereux, comprenant une protection d'aluminium (2), par exemple sous la forme d'un composite constitué d'une feuille d'aluminium (2) portant un film de polyester (1) et une couche d'un composé organique du type polyéthylène (3) collé au moyen d'une préparation aqueuse d'un alcool polyvinylique, formant un film étanche. Le vêtement comprend, en outre, un masque à gaz autonome avec une source d'oxygène et une cartouche d'un absorbant de CO2 pour absorber le gaz carbonique expiré. Ce vêtement est à usage unique.
