  • Patent number: 5925009
    Abstract: Alginate fabrics have, in conjuction with charcoal cloth, been used in wound dressings for malodorous wounds and there are commercial examples of such wound dressings. A problem associated with known alginate wound dressings which employ charcoal cloth is that the dressing is a relatively rigid structure. Furthermore, the known dressings have been constrained to the use of charcoal cloth which limits the absorptive properties thereof for wound odorants due to the fixed surface area of the cloth. We have now developed an alginate fabric which alleviates the above problems, and there is provided by the present invention an alginate fabric having particulate charcoal dispersed therein.
