    Abstract: The present invention is directed to an absorbent composite containing superabsorbent material. The superabsorbent material is in the form of superabsorbent particles having a bimodal particle size distribution. Use of superabsorbent material having a bimodal particle size distribution in the absorbent structure results in enhanced fluid distribution and fluid intake of the absorbent composite. The absorbent composite of the present invention is useful in disposable personal care products.

  • Publication number: 20030129915
    Abstract: A process is provided for forming a super absorbent composite for use in personal hygiene products, comprising a non-woven core with SAP uniformly distributed throughout the thickness of the core and bonded to the core with an adhesive. A non-woven core is provided to a processing line. An adhesive is introduced throughout the thickness of the core. Then the core is impregnated with a super absorbent polymer by blowing a stream of super absorbent polymer and air onto the core at a sufficiently high velocity to cause the super absorbent polymer to penetrate the surface of the core. The super absorbent polymer is distributed uniformly throughout the cross-section of the non-woven core and immobilized by the adhesive. Alternatively, the super absorbent polymer is blown into a non-woven core without adhesive and immobilized by a fiber matrix in the non-woven core.

  • Patent number: 6589892
    Abstract: An improved nonwoven web composite is formed by combining bicomponent thermoplastic filaments having adhesive properties with a component selected from other fibers and particles. The bicomponent filaments include distinct regions of first and second incompatible polymers across a cross-section of individual filaments. After the bicomponent filaments are combined with the other fibers and/or particles, the adhesive properties of the bicomponent filaments result in a web or matrix of filaments having improved ability to entrap, ensnare and contain the other fibers and/or particles within the web or matrix. The nonwoven web composite is particularly useful for making absorbent articles, which require stability and optimum levels of absorbent fibers and/or particles.

The web can be formed by selective deposition of airlaid materials including absorbents, such as pulp and superabsorbents, together with binder fibers. The web so constructed will have a plurality of intermingled lower basis weight areas and higher basis weight areas coexisting and distributed in at least a central region of the web, the alternations crossing the X axis or Y axis, or both, of the web, with the higher basis weight areas being a greater thickness in the Z-direction than the lower basis weight areas. The web so constructed will further have no discrete material boundaries between the lower basis weight stripes and the higher basis weight stripes. Further the necessity of later processing on the web to achieve a ridged structure is removed and the fibers will remain whole and undisturbed.

    Abstract: A web of thermoplastic multicomponent substantially continuous fibers is thoroughly and evenly mixed with absorbent materials prior to deposition on the forming wire to result in superior adherence of the absorbents to the thermoplastic components and hence result in superior performance of the web. The multicomponent fibers have a low melting point sheath which can be fully activated to melt and wet the absorbent particles. The web can then be densified and cooled, securing the absorbents to the web with hardened flow joints and enabling the web to carry high loadings of absorbent while maintaining good web integrity.

    Abstract: The invention is directed to a nonwoven material made of a bicomponent fiber in which the first polymer is a cellulose ester polymer, preferably cellulose acetate, and the second polymer is selected from the group consisting of polyolefins, polyesters, polyamides and polyimides. The bicomponent fiber can be either a side-by-side or a core-and-sheath fibers. When core-and-sheath, the cellulose acetate is the sheath polymer. The nonwoven material of the invention can be used to prepare grips, materials for use in absorbent products such as diapers and personal hygiene products, disposable towels and other products. The nonwoven of the invention has particular utility for disposable diaper products due to the superior fluid acquisition, retention and distribution properties of the cellulose ester, yet avoids the high cost of all cellulose acetate fibers by use of a much less expensive second polymer to form part the bicomponent fiber.

  • 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.
