ABSTRACT:
A biocidal fabric in which a pattern of clusters of biocidal beads are adhered between an air pervious substrate and a cover which may be gas impervious, water-vapor pervious or gas pervious. In the method and appratus for making the fabric, a pattern of hot melt adhesive is applied to the substrate and beads of biocidal material are sprinkled over the adhesive, after which the excess beads are removed. The same pattern of adhesive is applied to the cover and the cover adhesive is brought into contact with the beads on the substrate to complete the fabric.
