    摘要： Disclosed is a process of making an superabsorbent composite material which contains a hydraulically-needled fibrous web and superabsorbent materials. The method includes the steps of providing a nonwoven fibrous web; hydraulically needling the nonwoven web to enhance its liquid distribution properties; and introducing dry superabsorbent materials into intimate bonding contact with at least one surface of the hydraulically needled fibrous web. Also disclosed is the superabsorbent nonwoven composite material made by the described process. The hydraulically needled fibrous web component of the material may contain pulp fibers, synthetic fibers, natural fibers, bicomponent fibers, continuous filaments or mixtures thereof. The superabsorbent composite material has a saturation capacity greater than about 500 percent and a wicking rate greater than about 12 centimeters per 15 minutes. The superabsorbent composite material may be used as a liquid management material in an absorbent product or absorbent structure.

    摘要： The disclosure describes a commode liner made from a first and a second opposing member defining a top with an opening, a bottom, and a pair of opposing sides. The pair of opposing sides includes a separation distance D, which varies from the top to the bottom, and the distance D is larger at the top than at the bottom. The opposing members can be formed from a latently dispersible barrier composite material including an exposed low strength barrier component, an internal water sensitive layer, and a water permeable, inextensible, water dispersible support layer. When exposed to aqueous conditions on the barrier side, the composite prevents it from passing through to the other layers. When exposed to aqueous conditions on the opposite side, the commode liner readily disperses and may be disposed of by flushing in a toilet, for example. Examples of barrier layers include polylactic acid. Examples of water sensitive layers include polyvinyl alcohol. Examples of support layers include low stretch grades of toilet tissue.
