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.

Wound dressings and wound inserts comprising a porous film layer and at least a channel, wound inserts of forming wound inserts comprising a porous film layer and at least a channel, and wound-treatment wound inserts.

The disclosed technology relates to methods of manufacturing a fabric (100) for a wound dressing in which a knitting machine (500) is configured to knit a plurality of yarns to form a knitted fabric (100), and a fabric formed according to the method. The disclosed technology also relates to a system, a computer program and a non-transitory computer readable medium.

In manufacturing a pleated stretchable composite member, a first sheet-like nonwoven fabric and a stretched cord-like elastic member (rubber thread, etc.) are positioned on the protruding surface side of a pattern roll, and a hot melt adhesive is intermittently applied to the stretched cord-like elastic member and the first sheet-like nonwoven fabric at locations where the protruding surface of the pattern roll is present, and then the stretched cord-like elastic member and the first sheet-like nonwoven fabric intermittently coated with the adhesive and a second sheet-like nonwoven fabric are integrally adhesively fixed at positions corresponding to locations where the protruding surface of the pattern roll is present. In the stretchable composite member, the valleys of the upward-facing breathers of the top-layer nonwoven sheet and the valleys of the downward-facing breathers of the bottom-layer nonwoven sheet are adhesively fixed via a stretchable elastic members (rubber threads) between the two nonwoven fabric sheets.

Wound dressings and wound inserts including a porous film layer and at least a channel, forming wound inserts including a porous film layer and at least a channel, and wound-treatment wound inserts.

A vented wound dressing barrier includes one or more membrane layers with a plurality of vents. The vents are cut along a perimeter of the vents through the one or more membrane layers. Each vent having a connection portion uncut relative to the one or more membrane layers thereby forming a hinge configured to allow the vents to open for drainage when exposed to fluid underlying the vented wound dressing barrier. The plurality of vents is each cut along the perimeter without removal of any of the membrane layer. The one or more membrane layers with the plurality of vents has a surface for covering a wound, the surface area in the absence of a fluid pressing on the vents having no openings or voids which reduce the surface area of a vented wound dressing barrier area covering a wound.

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.

Embodiments disclosed herein relate to moldable decorative splint materials and associated methods of manufacture. The splint material may include a plurality of decorative elements integrated with the splint material. The decorative elements may be interconnected within a network of flexible connectors via a plurality of supports. Each support of the plurality of supports may include a retaining edge that retains the decorative element within the support.

A method for treating a wound that includes incorporating a wound dressing comprising a plurality of fibers, each fiber having a length of at least two (2) inches, into a wound to cause the walls of the wound to remain apart and allow the wound to heal from the inside to the outside, and removing the wound exudate.

The present disclosure provides a superabsorbent dressing comprising non-woven protonated chitosan fabric/sheet that shows superior fluid absorption and retention capacity, enhanced tensile strength and coherency. The superabsorbent dressings of the present disclosure comprise chitosan fibers composed of chitosan amide and an acid salt of chitosan. The present disclosure also provides a continuous method and a device for manufacturing the chitosan dressings of the disclosure.
