Non-occlusive composite wound dressing are disclosed that comprise a natural polymer wound-healing layer comprised of isolated polymer fibers, and a synthetic polymer foam layer having at least one surface physically adhered to said natural layer by the physical interlocking of said polymer fibers with said surface. Also disclosed is a process for the preparation of a non-occlusive composite wound dressing comprising contacting a synthetic polymer foam porous surface with a solution and/or suspension of natural polymer fibers in a medium, and removing said medium from said fibers under conditions that result in said fibers penetrating into pores of said surface and that form a dried composite of said synthetic polymer foam adhered physically to a layer comprising natural polymer fiber. |
