<p>A layer of a non-woven or open-woven or open-knitted charcoal cloth is supported on a layer of a textile material having fibers needle-punched through the charcoal cloth. This composite material can be incorporated in various multi-layer structures having, for example, a further textile layer and/or a microporous or similar layer on the other side of the charcoal cloth. Such multi-layer structures may be used in protective clothing, as filter materials or in medical dressings, or in the manufacture of moulded articles such as face masks.</p> |
