<p>The invention relates to a filter sheet material composed of an air-permeable, flexible, especially textile supporting layer, on which there is imprinted in a certain pattern a mixture containing an adsorbent in powder form and a polymeric binding agent, the adsorbent covering up to 90% of the surface of the supporting layer. The invention furthermore relates to the use of such filter sheet materials with active carbon as adsorbent for protective clothing, and to the preparation of the material by rotary screen printing from a paste made of the powdered adsorbent and a dispersion of the polymeric binding agent.</p> |
