A fluid distribution material for use in an absorbent article includes a formed film layer having a user-facing side and a garment-facing side opposite the user-facing side. The formed film layer includes a plurality of apertured protuberances arranged in a pattern having 10 to 40 protuberances per linear inch. Each of the protuberances includes a continuous sidewall extending from the user-facing side. The garment-facing side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. A nonwoven layer is laminated to the garment-facing side of the formed film layer. The nonwoven layer includes a plurality of continuous fibers extending across the land areas and the plurality of apertures of the formed film layer and attached to the land areas at bond sites. The fluid distribution material has a compressibility of less than 10% between pressures of 0.21 psi and 0.60 psi.

The present invention relates to multi-layered non-woven structures being useful as components of disposable absorbent articles and garments comprising super absorbent particles and thereby acts as a core. The invention thereby ensures that the body fluids can penetrate from a first layer, which acts as an acquisition layer, up to a third layer comprising SAP particles, the second non-woven layer serving to decrease the fluid volume per surface unit, as a conventional dispersion layer. However the second layer of the invention additionally acts like a non-return valve, preventing, or at least strongly limiting, any fluid transfer from the third layer to the first layer. Channels free of SAP can additionally be design to improve the inlet and rewet properties of the multilayer acquisition and distribution sheet non-woven material.

Dressings for tissue treatment with negative pressure and methods of assembling the dressings for tissue treatment with negative pressure are disclosed. A method of assembling a dressing, which may comprise at least three layers assembled in a stacked relationship, may comprise providing an assembly station having at least one retaining pin, placing a first layer on the assembly station, placing a second layer on the assembly station, and bonding the second layer to the first layer. The first layer may comprise a plurality of apertures, at least some of which may be engaged by the retaining pins, and the second layer may comprise fluid restrictions and alignment areas for engaging with the retaining pins so that the fluid restrictions may be aligned with the apertures of the third layer.

A dressing for treating a tissue site with negative pressure may comprise a tissue interface comprising a three-dimensional textile of polyester fibers and a polymer coating on the polyester fibers. In some examples, the three-dimensional textile may be a three-dimensional weave of polyester fibers, and the polymer coating may be hydrophobic. In more particular embodiments, the polymer coating may be silicone or polyethylene, for example. The dressing may additionally include a drape disposed over the tissue interface and a port fluidly coupled to the tissue interface through the drape. The tissue interface may be applied over a tissue site, and therapeutic levels of negative pressure may be applied to the tissue site through the tissue interface.
