Disclosed is a unitary absorbent structure including a fluid acquisition stratum; a fluid distribution stratum; and a fluid storage stratum between the acquisition stratum and the distribution stratum. Each of the acquisition, distribution, and storage strata are in fluid communication with each other.

Unitary fluid acquisition, storage, and wicking material

Disclosed is an absorbent structure including a liquid acquisition layer and a fibrous liquid storage layer in liquid communication with the acquisition layer. The storage layer includes SAP particles. The acquisition layer includes synthetic fibers and the fibers are latex bonded. A fluid acquisition and/or distribution layer (ADL) containing at least two layers, a top layer of latex bonded synthetic fibers and a bottom layer of latex and/or thermal bonded cellulose fibers and method for preparation thereof are disclosed. The synthetic fiber layer is highly porous and provides rapid fluid acquisition under load. The cellulose layer provides z-direction capillary force to pull fluid into the absorbent product, to provide temporary fluid immobilization, and to act as a conduit for fluid to be pulled into unsaturated portion of the permanent fluid storage layer. The ADL of the invention provides increased protection against leakage relative to single-layer ADLS.

Absorbent structures having fluid acquisition and distribution layer

A discrete superabsorbent layer is adhered to the lower surface of a fibrous absorbent structure using a water-based polymeric binder is disclosed. The advantages are that a superabsorbent roll good can be prepared for later conversion into disposable absorbent products. The use of the water-based polymeric binder prevents particles of superabsorbent from becoming dislodged from the structure during handling and processing.

Absorbent structures with integral layer of superabsorbent polymer particles

An absorbent sheeted material containing a layer of a foamed hydrogel-forming polymer having superabsorbent properties coated on the surface of a sheeted fibrous absorbent material suitable for use in disposable absorbent products and methods of making thereof are disclosed.

Absorbent structures coated with foamed superabsorbent polymer

A liquid acquisition layer is inserted between a porous cover sheet and an absorbent core of an absorbent article such as a disposable diaper. The liquid acquisition layer is made from polymer fibers bonded by an adhesive, with the adhesive rendered insoluble by curing. The cured adhesive has a glass transition temperature in excess of 30.degree. C. and preferably above 37.degree. C., which is normal body temperature. This allows the acquisition to remain resilient and retain void volume when heated by the body or body liquids.

Liquid acquisition layer for personal absorbent article

The disclosure describes an absorbent core, free of wood pulp or other cellulosic materials. The core includes two thin outer layers, with at least one layer being porous and receptive to body liquids. A quantity of superabsorbent polymer particles of a particular type is provided between the outer layers and is loosely contained in individual unbonded open zones or flat closed pockets defined by a plurality of intersecting heat bond lines between the layers, with the lines defining a densified and a hot calendar-bonded fiber structure to provided wicking lines or flow zones between the pockets. The dry product is a flat, thin partial laminate.

Absorbent core for absorbing body liquids and method

An absorbent article has an absorbent core and a liquid permeable top sheet made of polyolefin material. An acquisition layer is provided between the top sheet and the core. The acquisition layer is a nonwoven fabric made from polyolefin fibers bonded by a cured resin. The acquisition layer has a larger pore size than the top sheet and is treated with a surface active agent to render it hydrophilic.

Absorbent composite article having fluid acquisition sub-layer

A heat shrinkable nonwoven fabric includes outer layers of thermoplastic staple fibers and an inner layer containing heat shrinkable fibers the layers are point bonded together at spaced locations without causing shrinkage of the heat shrinkable fibers. The web may then be uniformly heated in a relaxed state to cause a substantial increase in bulk.
