Abstract
A wound dressing containing a multi-ply knit fabric, where the fabric contains a first and a second knit ply. The first knit ply contains a plurality of first yarns and forms the upper surface of the fabric. The second knit ply contains a plurality of polytetrafluoroethylene (PTFE) yarns, where the PTFE yarns have a transmission in the IR region of 8-10 μm at least about 40%, and a thermal conductivity of at least about 0.2 W/(m·K) forms the lower surface of the fabric. The first ply and the second ply are integrated through combined portions formed by interlacing first yarns among the PTFE yarns of the second knit ply, interlacing PTFE yarns among the first yarns of the first knit ply, or interlacing a plurality of third yarns among the first yarns and the PTFE. The multi-ply knit fabric also contains a composition containing at least one silver ion-containing compound.
