  • Publication number: 20250017294
    Abstract: Embodiments of the present disclosure generally relate to coated substrates having, e.g., anti-viral properties, to articles including the coated substrates, and to processes for making such coated substrates and articles. In an embodiment, a coated substrate is provided. The coated substrate includes a substrate having a weight of about 120 g/m2 or less according to ASTM D3776, mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the substrate wherein the coated substrate has a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less.

  • Publication number: 20220030980
    Abstract: Embodiments of the present disclosure generally relate to coated substrates having, e.g., anti-viral properties, to articles including the coated substrates, and to processes for making such coated substrates and articles. In an embodiment, a mask for preventing infection by a virus is provided. The mask includes a coated substrate having a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less and a water droplet absorption time of less than about 5 seconds. The coated substrate includes a non-woven fabric having a weight of about 120 g/m2 or less according to ASTM D3776, and mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the non-woven fabric.
