  • Publication number: 20070254544
    Abstract: According to one embodiment, the invention relates to a method for disinfecting a non-porous textile fabric. The method includes providing a non-porous textile fabric comprising a barrier system having a fluid barrier property. The barrier system blocks the passage of harmful microorganisms through the non-porous textile fabric. The method further includes selecting a disinfectant such that (1) the disinfectant does not substantially diminish the fluid barrier property of the barrier system upon application to the non-porous textile fabric, and (2) kills the harmful microorganisms. The method also includes applying the disinfectant to the non-porous textile fabric to kill the harmful microorganisms residing on the surface of the non-porous textile fabric. In at least one embodiment, the disinfectant includes a quaternary ammonium compound.
