ABSTRACT This study evaluated the frictional properties of the skin‐contact interfaces of two multilayer prophylactic dressings under simulated perspiration conditions. The tested dressings were identical except for the skin‐contact interface, which was either silicone‐made or Hydrofiber‐made, that is, AQUACEL Hydrofiber Technology.
