    • 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.
    • 本发明提供了具有第一表面和第二表面的流体透过性纤维,优选非织造纤维网。 纤维网包括亲水性非织造纤维网,其包含彼此相关联的多个单独的,优选白化的,增亮的和/或不透明的纤维。 幅材包括多个表面能量梯度,该表面能量梯度由位于第一表面上的不连续的间隔区域的边界限定,其表现出与幅材的相邻部分不同的表面能。 这些区域包括随机分布在第一表面上的优选白化,增亮和/或不透明的低表面能材料的沉积。 在优选的实施方案中,非织造纤维网由基本上非圆形横截面的成形纤维形成,优选三边形或三角形横截面,其包括纤维材料内的增白剂,增白剂和遮光剂。 优选地,低表面能材料包括材料本身内的增白剂和不透明剂,优选的材料包括包含二氧化钛颗粒悬浮液的可UV固化的有机硅树脂。 本发明的非织造纤维网可有利地用作吸收制品如尿布,卫生巾等中的顶片和/或第二顶片。
