  • Patent number: 5453314
    Abstract: Wearing apparel for protecting the wearer against radioactive contamination is manufactured from single use disposable laminated material which comprises a first continuous layer of non-macerating hypoallergenic cellulosic material for contact with the wearer's skin and a second continuous layer of cellulosic material exposed to external contamination. The first and second layers are bonded together with a third contiguous layer interposed between them. The third layer is of a microporous adsorbent material allowing passage of body vapors from the wearer to the ambient region while restricting passage of liquid in the opposite direction. The laminated material exhibits a tensile yield strength of at least approximately 2,000 psi, a shear yield strength of at least approximately 1,000 psi, and an overall coefficient of heat transfer of at least approximately 2.75 BTU/hr.ft.sup.2 -.degree.F. The microporous adsorbent material may be activated charcoal or hydrated alumina silicate.
