Definitions

  • the present invention relates to a protective article to protect the user from the risks associated with the handling of chemicals.
  • multilayer materials are usually used which comprise at least one layer of a material impervious to said chemicals, i.e. a barrier material.
  • a barrier material i.e. a material impervious to said chemicals.
  • the effectiveness of the barrier effect of a material is determined by its resistance to permeation, which is measured by the time it takes for a given chemical to pass through the material.
  • Materials used to make personal protective equipment must also have sufficient mechanical strength and puncture resistance for common use, such as in a laboratory or workshop.
  • a protective garment such as a glove which has a three-dimensional structure, which is devoid of seams or external welds and which is flexible is preferred. so that you can marry the user's movements. Finally, we also expect such a glove that it is resistant to water.
  • a barrier material provides protection against a limited number of chemicals.
  • a common solution is to superpose resistant gloves to each of these families in order to provide additional protection. This solution, resulting in a superimposition not very ergonomic, has the disadvantage of hindering handling.
  • the inner layer which is in contact with the skin of the user, is made of polyvinyl alcohol while the outer layer is made of rubber.
  • the outer layer of rubber which is resistant to water, is very easily degraded in contact with certain solvents organic. Therefore these gloves are not suitable for handling these chemicals.
  • Protective articles with a multilayer structure based on polyolefin and EVOH are also known: US 5, 491, 022 , US 5, 059, 477 , US 4, 855, 178 , US 5, 162, 148 .
  • These protective articles have the disadvantage of offering a low level of chemical protection against amines (methylamine, ethylamine, ..) and to have a low mechanical and thermal protection as well as a low elasticity.
  • these materials when assembled to produce a glove, have at the welds extra thickness relative to the rest of the material, which is not the case for articles obtained by dipping.
  • the object of the invention was to provide a barrier material for as many chemicals as possible for as long as possible. We have also tried to develop a glove resistant to water.
  • the document US-5,438,709 discloses an elastomeric glove covered with a layer of polyvinyl alcohol and a thickening agent.
  • the polyvinyl alcohol used is of a fully hydrolysed quality.
  • the gloves described in this document are more particularly intended to be used as a base for forming an orthopedic bandage, because of their slippery character in the presence of water.
  • the document JP 56-078930 discloses a textile glove which is dipped in a solution of polyvinyl alcohol and then dried and dipped in a dispersion of a polyvinyl chloride (PVC) resin, before being demolded. This process gives a textile glove that is pleasant and flexible contact.
  • PVC polyvinyl chloride
