ABSTRACT:
An allergen-barrier fabric includes a tightly-constructed fabric substrate, woven from 0 to 45% continuous synthetic filament yarns and 55 to 100% natural or synthetic spun yarns. The fabric substrate is finished to produce a fabric with a mean pore size of 4 to 10 microns, an air permeability of 0.5-25 cfm, a mean fabric flexibility of 0.5 to 6.5 grams (bending resistance), and a moisture vapor permeability in excess of 800 g/m2/24 hours. This fabric provides a barrier to mite-induced allergen particles. Various additional finishes can be included on the fabric. For example, an antimicrobial finish may be provided on the fabric to extend fabric wearlife by providing protection against mold and mildew. As another alternative, a fluorochemical finish can be provided to extend fabric wearlife by providing protection against fluid stains.
