The present invention relates to biocidal fabrics in which the aggregate of biocidal beads is attached between a gas impermeable, water vapor permeable or gas permeable cover and an air permeable substrate. In the fabrication method and apparatus thereof, the shape of the hot melt adhesive is applied to the substrate, the beads of biocidal material are spread over the adhesive, and excess beads are then removed. The same shape of adhesive is applied to the cover and the cover adhesive contacts the beads on the substrate to complete the fabric. |
