  • Publication number: 20140121626
    Abstract: The present invention is directed to a fluid-entangled laminate web and the process and apparatus for its formation as well as end uses for the fluid-entangled laminate web. The laminate web includes a support layer and a nonwoven projection web having a plurality of projections which are preferably hollow. As a result of the fluid-entangling process, entangling fluid is directed through the support layer and into the projection web which is situated on a forming surface. The force of the entangling fluid causes the two layers to be joined to one another and the fluid causes a portion of the fibers in the projection web to be forced into openings present in the forming surface thereby forming the hollow projections. The resultant laminate has a number of uses including, but not limited to, both wet and dry wiping materials, as well as incorporation into various portions of personal care absorbent articles and use in packaging especially food packaging where fluid control is an issue.

The wetness sensation member includes a permeable layer and a flow control layer. Urine deposited on the wetness sensation member can penetrate through the permeable body-facing layer in a z direction away from the wearer to the flow control layer. The flow control layer retards the passage of the urine through the wetness sensation member in the z direction while supporting the movement of the urine in an x-y plane to increase the wetted area contacting the wearer's skin and thereby enhance the wearer's awareness that urination has occurred. The visible highlighting is visible when viewing a body-facing surface of the article and may be associatively correlated with an externally visible marking and/or with the concept of toilet training.

  • Patent number: 7589251
    Abstract: A disposable absorbent article, such as a disposable diaper. The disposable absorbent article has a topsheet with apertures large enough for low-viscosity fecal material to pass through to a fecal material storage element. The fecal material storage element immobilizes the fecal material in position for dewatering, so that the solid components of the fecal material are separated from the liquid components of the fecal material and the liquid components can be absorbed by an absorbent core. This arrangement provides for easier cleaning of the wearer when the soiled disposable absorbent article is removed. The fecal material storage element may extend beyond one or more edges of the absorbent core.
