| 摘要 |
The present invention provides a fluid pervious fibrous, preferably nonwoven, web having a first surface and a second surface. The web comprises a hydrophilic nonwoven web comprising a plurality of individual, preferably whitened, brightened, and/or opacified, fibers associated with one another. The web includes a plurality of surface energy gradients defined by the boundaries of discontinuous, spaced regions of the web which are located on the first surface which exhibit a different surface energy than an adjacent portion of the web. The regions comprise depositions of a preferably whitened, brightened, and/or opacified low surface energy material randomly distributed over the first surface. In a preferred embodiment, the nonwoven web is formed of shaped fibers of substantially non-circular cross section, preferably a trilobial or delta cross section, which include whitening, brightening, and opacifying agents within the fiber material. Preferably, the low surface energy material includes whitening and opacifying agents within the material itself, with a preferred material comprising a UV curable silicone resin including a titanium dioxide particle suspension. The nonwoven fibrous webs of the present invention may be utilized advantageously as a topsheet and/or secondary topsheet in an absorbent article such as a diaper, sanitary napkin, or the like. |
