Abstract

An allergen-barrier fabric, woven from different fibers with various mix ratios, or 100% single fiber. The fabric has warp and filling yarns total from 253 to 2400 thread counts per square inch, generating a mean pore size ranging from 0.2 to 10 microns, thus being capable of barring minute allergen particles while retaining superior air permeability and comfort.
