Abstract: Non-occlusive composite wound dressings that comprises a material polymer wound-healing layer comprised of isolated polymer fibers, and a synthetic polymer foam layer having at least one surface physically adhered to the natural layer by the physical interlocking of the polymer fibers with the surface. Also, 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 the medium from the fibers under conditions that result in the fibers penetrating into pores of the surface and that form a dried composite of the polymer foam adhered physically to a layer comprising natural polymer fiber.
