Abstract
Protective composite material suitable for the making of protective garments to afford protection against noxious and toxic chemicals in the form of vapors, aerosols and particulates. The material comprises a water permeable and essentially pore-free air impermeable polymer ply sandwiched between an air and water permeable cover ply and an adsorbent substance-bearing and air and water permeable inner ply. Various embodiments of such protective material and modes of making it are disclosed.
Claims20
A protective composite material, comprising at least one continuous, water permeable and essentially non-porous and non-foamed synthetic polymeric material sandwiched between an air and water permeable cover ply and an adsorbent substance-bearing and air and water permeable inner ply.
An article of protective clothing made of a composite material comprising at least one continuous, water permeable and essentially non-porous and non-foamed synthetic polymeric material sandwiched between an air and water permeable cover play and an adsorbent substance-bearing and air and water permeable inner ply.
A flexible protective composite material, comprising an air and water permeable outer fabric ply, a substantially continuous and essentially non-porous and non-foamed synthetic polymeric film having a water permeation rate of less than 300 g/m.sup.2 /h as an intermediary ply, and an air and water permeable fabric inner ply bearing an adsorbent substance capable of interaction with noxious materials by either of adsorption and chemical reaction.
