allergic barrier fabrics, mattress, pillow, bedding material, and lining for an allergen susceptible article

摘要

mattress, pillow, bedding material, lining for an allergen-susceptible article and allergen barrier fabric. The present invention relates to an allergenic barrier fabric comprising at least one porous layer of polymeric nanofibers, an overlying tissue layer adhered to the nanofiber layer and optionally an underlying tissue layer adhered to the nanofiber layer. that the layers of the overlying fabric and the underlying optional layer are adhered to said nanofiber layer, so that the allergenic barrier fabric has an average flow pore size of between about 0.01 pm and about 10 pm, and a air permeability of at least about 1,5 m ^ 3 ^ / min / m ^ 2 ^.
