ABSTRACT:
The present invention relates to fluid pervious, dispersible, and flushable webs particularly suited for use in a disposable absorbent article, such as a diaper, sanitary napkin, panty liner, incontinence pad, or the like. The present invention further relates to such webs which also include an improved, functional textured surface so as to be suitable for use as a topsheet on such a disposable absorbent article.
The present invention provides a fluid pervious web which disperses into fragments which are readily flushable in a normal toilet. The web preferably comprises a wetlaid apertured tissue having a temporary wet strength resin incorporated therein. The web preferably further includes a plurality of individual fibrils on a body-facing surface thereof, so as to provide a clean and dry tactile impression in use. The fibrils serve to separate the wearer's skin from the underlying tissue substrate in use. In a preferred embodiment, the web substrate is hydrophilic in nature while the fibrils themselves are hydrophobic in nature, so as to provide enhanced dryness at the uppermost surface while promoting rapid acquisition properties.
