In the preferred embodiment of the present invention, the cells are constructed by providing hydrophobic barriers in the absorbent layer. The barriers can be constructed from paraffin, plastic, or any other material that can penetrate the absorbent layer. In one embodiment of the present invention, a hydrophobic layer is bonded to the top surface of the absorbent layer.

  • Publication number: 20020168910
    Abstract: The invention concerns a method for producing a complex nonwoven fabric which consists in continuously producing a complex wherein a first web of a cellulosic fibres (4) is continuously sandwiched between two webs of spunbonded filaments (2, 7), and which consists in: producing a first web of spunbonded filaments (2), the bundle of extruded and drawn filaments being received on a mobile conveyor belt (3) in the form of a non-bonded lap; depositing on said web 92) by airlaid process a second web of cellulosic fibres (4); depositing on the textile web (4) a second web (7) of non-bonded continuous filaments; transferring the resulting complex onto an installation (9) for water-jet bonding and hydro-entanglement consolidation; and in drying the nonwoven mixed product and then recuperating it, for example in the form of a cloth wind-up (18).

  • Patent number: 6479415
    Abstract: 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.

  • Publication number: 20020132548
    Abstract: Wet-laid nonwoven webs having mechanical reinforcement properties are provided by employing unpulped vegetable fiber bundles as the predominant fiber component. The unpulped fiber bundles have a modulus of elasticity of about 2-5×10 6 psi and a chopped fiber length of about 25 mm. The fibers are cordage fibers including sisal, abaca, henequen, kenaf and jute. Composites of the unpulped fiber webs with cellulosic and spunbonded sheets find application as thermoformed vehicle interior trim products.

  • Patent number: 6436234
    Abstract: Paper sheets useful for tissues, paper towels, napkins, disposable absorbent products and the like can be made to exhibit a high degree of wet resiliency. This property is achieved by using a combination of high yield pulp fibers (such as bleached chemithermomechanical pulp fibers) and a wet strength agent in an uncreped throughdrying process. The resulting product, when wetted, can spring back after being crumpled in one's hand.

  • Publication number: 20020034914
    Abstract: A multi-component nonwoven fabric can be formed with integrated liquid-acceptance and liquid-distribution layers by hydroentanglement on a three-dimensional image transfer device. Appropriate fiber selection promotes efficient fluid management, with the fabric optionally being provided with a liquid-retention layer. The invention further contemplates the formation of liquid-retention layers by hydroentanglement, with such layers exhibiting desirably high structural integrity, while providing the desired absorbent characteristics required for use in disposable absorbent products.

  • Publication number: 20020031635
    Abstract: The invention relates to an absorbent insert for foodstuff packagings, the liquid-absorbing component of which is a superabsorbent polymer which, in a hitherto unrivaled fashion, persistently absorbs and retains large quantities of liquid even under high pressure load, protects the foodstuffs from bacterial decay, and prevents contamination of the packagingd goods by migrating soluble constituents of the polymer. This combination of properties of the superabsorbers used is expressed by the QSAP 0.3 quotient of retention according to the tea bag test+absorption against pressure (AAP) 0.3, divided by the amount of solubles (LA), which quotient is at least 20. Superabsorbers having such properties are obtained by using special combinations of crosslinkers. Furthermore, the invention relates to a process for producing said absorbent inserts and their use in foodstuff packagings, as ice substitute, and as leak-proofing means in transport packagings.
