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.

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.

摘要翻译： 本发明提供一种具有多个不连续单元的吸液性纤维基材，其中设置有第二材料。 该第二材料选自多种有机或无机固体，其可提供增强效果，使得防止锋利的仪器通过新的复合结构。 增强材料以细胞形式以不连续的阵列布置在纤维基质中，从而为液体吸收到所述纤维基质中提供途径，同时所述增强材料提供对尖锐边缘器械的穿透抵抗力。 当以这种方式设置时，由于增强材料不以连续图案设置，因此保持柔性。 优选地，所设置的图案没有提供用于锋利边缘的连续穿透线的线性区域。 更优选地，图案被设计为将所述线性区域约束到基本短的长度的互锁形状的图案。 增强细胞图案可以在所述吸收性纤维基材上方压花，或者可以与所述纤维基材基本共面。 复合衬底也可以用液体不可渗透层支撑，或作为施加到其底表面上的独立层，或作为施加的涂层。 液体不可渗透的表面可以有效地选择具有高的摩擦系数以提供非滑动表面。
