    摘要: The present invention provides a liquid absorbent fibrous substrate having a plurality of discontinuous cells in which a second material is disposed. This second material is selected from a broad variety of organic or inorganic solids which may provide a reinforcing effect such that a sharp instrument is prevented from passing through the new composite structure. The reinforcing materials are disposed in a discontinuous array, in a cellular form in the fibrous substrate thus providing a path for liquids to be absorbed into said fibrous substrate, while said reinforcing materials provide resistance to penetration by sharp edged instruments. When disposed in this manner, flexibility is maintained since the reinforcing materials are not disposed in a continuous pattern. Preferably, the pattern disposed is free of linear regions that provide a continuous line of penetration for sharp edges. More preferably, the pattern is designed with a pattern of interlocking shapes which constrain said linear regions to essentially short lengths. The reinforcing cellular pattern may be embossed above said absorbent fibrous substrate or may be substantially co-planar with said fibrous substrate. The composite substrate may also be backed with a liquid impervious layer, either as a separate layer applied thereto the bottom surface, or as an applied coating. The liquid impervious surface may be usefully selected with a high co-efficient of friction to provide a non-skid surface.

    摘要: A dispersible absorbent product comprises a mechanically weakened fibrous web. The dispersible absorbent product can absorb a sufficient amount of fluid without becoming overloaded and suffering from leakage, and is dispersible using a standard toilet. The mechanically weakened regions of the web enhance the dispersibility of the product. Additionally, the dispersible absorbent products may be pre-moistened with a composition. The pre-moistened products are stable in storage, easily dispersible down a toilet, and deliver cleaning, conditioning, and like benefits. Methods of making such dispersible absorbent products are also disclosed.

    摘要: Provided are highly dispersible absorbent products, comprising an absorbent structure and preferably a water soluble barrier layer, wherein the absorbent products have a high rate of dispersibility, can exhibit low residual by-product in urinals upon flushing, resist strikethrough of absorbed fluid onto the hand of the user, and can absorb a sufficient amount of fluid without becoming overloaded or leaking. In one embodiment, provided is a ring rolled cellulosic sheet having a water soluble polymeric film laminated thereto. Also provided is a method of making such dispersible absorbent products comprising mechanically weakening an absorbent structure. Also provided are packaged products comprising a package and a plurality of dispersible absorbent products or articles. Also provided is a method for absorbing residual urine that can be both discreet and convenient, comprising absorbing residual urine subsequent to urination with a dispersible absorbent product of the present invention and depositing product in a toilet or preferably a urinal.
