    摘要: Wound dressings and methods of manufacturing wound dressings are provided. The wound dressings include portions that are converted from a moisture vapor permeable material to a material having reduced moisture vapor permeability. The conversion may be accomplished in a variety of ways. In some embodiments, a solvent is used to dissolve a porous material to thereby form a non-porous film. In other embodiments, heat is applied to melt a porous material to thereby form a non-porous film. The heat may be applied using a heated gas or a heating element to directly or indirectly heat the material.

    摘要: Disclosed herein is a wound dressing. The wound dressing includes a first fiber layer and a second fiber layer stacked on and bound to the first fiber layer. The first fiber layer consists of a plurality of a first fiber that are made of an alginate wherein the first fibers are respectively bound with one another, and are substantially extended in parallel along a first direction. The second fiber layer consists of a plurality of a second fiber that are made of an alginate, wherein the second fibers are respectively bound with one another, and extend in parallel along a second direction that is not parallel to the first direction. The second layer is stacked on the first layer with the second fibers being bound with the first fibers. The first fibers and the second fibers respectively have a length such that the wound dressing has a breaking strength for at least 1.5 kg.
