    • The present invention is directed to a dry cleansing cloth that comprises at least one personal care composition imparted to the cloth, wherein the composition acts as a visual indicator of the compositions depletion with each use, eventually signaling the consumer for the need of a replacement cloth. Accordingly, the cloth of the present invention may be any suitable limited use substrate, including wovens, nonwovens, films, and combinations thereof. Preferably, the limited use cloth comprises a nonwoven substrate, wherein the nonwoven substrates may include, but are not limited to airlaid fabrics, wetlaid fabrics, spunlace fabrics, spunbond fabrics, meltblown fabrics, coform fabrics, entangled spunbond fabrics, and combinations thereof.

    • A method and apparatus are disclosed for forming a pattern of low basis weight regions, such as apertures or perforations, in an unbonded fibrous web. The present apparatus includes a forming surface having a pattern of forming elements, with an unbonded web positioned in operative association with the forming surface. Differential air pressure is applied to the web so that a pattern of low basis weight regions is formed corresponding to the pattern of forming elements. The fibrous web is thereafter removed from the forming surface, and can be further processed, if desired, such as by application of binders or other finishes, and can be integrated with associated components for various end uses, including medical, industrial, and hygiene applications.
    • 公开了用于在未粘合纤维网中形成低基重区域(例如孔或穿孔)的图案的方法和装置。 本发明的装置包括具有形成元件图案的成形表面,其中未粘结的纤维网定位成与成形表面有效结合。 将差压空气压力施加到幅材上,使得对应于成形元件的图案形成低基重区域的图案。 此后,纤维网从成形表面上移除,如果需要,可以通过使用粘合剂或其它表面处理剂进一步加工,并且可以与用于各种最终用途的相关组件(包括医疗,工业和卫生应用)相结合 。
