Abstract
The invention proposes a composite textile material for NRBC applications, comprising a first material capable of providing a physical barrier to the penetration of microorganisms and a second material capable of trapping, by absorption and/or adsorption, said microorganisms stopped by said first material and article of protection made of said material.
Claims13
A composite textile material for NRBC applications, comprising:
- a first non-woven material configured to create a physical barrier to penetration of an aerosol of microorganisms, said first material being a spunbond meltblown spunbond barrier non-woven fabric;
- a second material that is able to trap—by absorption and/or adsorption—said microorganisms being stopped by said first material, said second material being selected from non-woven polyesters;
- and
- a third substrate material selected from foams impregnated with activated carbon that can support said second material,
- wherein the composite textile material provides an air-permeability of 10 l/m2·s to 1000 l/m2·s measured at 100 Pa and a limited penetration of 2.4% at 0.3 cm/s of said aerosol.
