DURABLE, COMFORTABLE, AIR-PERMEABLE AND ALLERGEN- BARRIER FABRIC

摘要

PROBLEM TO BE SOLVED: To overcome various disadvantages of known allergen-barrier fabric materials and to provide a fabric which is soft and comfortable but still provides an effective barrier against transmission of dust, dust mites, excrement thereof and other allergens. SOLUTION: This allergen-barrier fabric includes a tightly-constructed fabric substrate, woven or knitted from 0-45% of continuous synthetic filament yarns and 55-100% of natural or synthetic spun yarns. The fabric substrate is finished to produce a fabric with 4-10μm mean pore size, 0.5-25 cfm air permeability, 0.5-6.5 g mean fabric flexibility (bending resistance) and >800/m2/24 h moisture vapor permeability. The 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 molds and mildews. As another alternative, a fluorochemical finish can be provided to extend the fabric wearlife by providing the protection against fluid stains.
