The disclosure provides methods of treating a wound using negative pressure wound therapy by contacting a wound with a porous fibrin foam dressing and applying negative pressure on the wound, wherein the fibrin foam includes a three-dimensional reaction product of fibrinogen and thrombin and is biodegradable in vivo. Further provided is a dressing material for negative pressure wound therapy comprising a porous fibrin foam that can substantially conform to a shape of the wound, wherein the fibrin foam includes a three-dimensional reaction product of fibrinogen and thrombin, is biodegradable in vivo, and does not need to be changed during the course of therapy.

Disclosed herein is a hydrogel wound dressing having a wound-contact side and a non-wound-contact side wherein the rate of moisture evaporation from said non-wound contact side is faster than the rate of moisture evaporation from said wound contact side, thereby causing said dressing to curl toward said non-wound contact side upon drying. Optionally, the hydrogel wound dressing can be comprised of two materials having different rates of moisture evaporation bonded together to form a bilayer structure.

According to the invention, a wound dressing may be further developed, whereby a wound dressing made from a planar structure with a first main direction of extension and at least one further main direction of extension, whereby the textile planar structure, at least along the main directions of extension comprises extensibility properties which differ by less than 80%, preferably less than 50%.

A method of making an absorbent insert for absorbing fluid in a root canal. Forming a body in a pre-compressed state prior to use, having a matrix of absorbent material. The matrix of absorbent material swells upon absorbing fluid after the body in the pre-compressed state has been inserted into the root canal. In the forming process, a sheet of absorbent material is compressed to form a compressed sheet, which is cut and shaped to form an insert. Cutting and shaping is by using complementary split mold halves which together define a cavity corresponding to the body of the insert and stamping the compressed sheet with the split mold halves to form the body of the insert.

Three-dimensional laminates and methods for making the same are provided. The three-dimensional laminates may be apertured and may have welds between various substrates. The three-dimensional laminates may be used in absorbent articles, such as diapers and pants, for example, as topsheets, as topsheets and acquisition layers, or as outer cover materials, for example. The three-dimensional laminates may be produced on an absorbent article manufacturing line.

An absorbent composite includes a porous base layer, a core layer, and a superabsorbent laminate layer. The core layer has a fluff pulp layer and superabsorbent polymer particles. The core layer is disposed on the base layer. The superabsorbent laminate layer is disposed on the core layer. The base layer, the core layer, and the superabsorbent laminate layer are compressed together and embossed under heat and pressure to form a plurality of embossed depressions. The embossed depressions are arranged across a major surface area of the superabsorbent laminate layer. The embossed depressions extend through the composite from the superabsorbent laminate layer and into the core layer and the base layer. A thin, soft, and pliable absorbent composite suitable for a variety of applications including wound care is thereby provided.

Methods and tooling for forming performance zones in substrates are provided. The methods and tooling for forming performance zones in substrates may be for use on an absorbent article manufacturing line.

Methods and tooling for making three-dimensional substrates and/or apertured substrates are provided. The three-dimensional substrates and/or apertured substrates may be used in absorbent articles, such as diapers and pants, for example. The methods and tooling may be used on an absorbent article manufacturing line.
