Abstract
A wound cleaning product is described as used for sterile debridement of wounds. The wound cleaning product comprises a composite material having a foam layer and a fiber layer arranged on a surface of the foam layer. The fiber layer is at least partially thermally solidified, and the foam layer and the fiber layer are connected to one another by needling such that fibers of the fiber layer have penetrated into the foam layer and form capillary channels that extend from the fiber layer into the foam layer.
