Cleaning articles comprising a cellulosic fibrous structure having discrete basis weight regions treated with a high internal phase inverse emulsion

摘要

Disclosed are articles useful in cleansing, and particularly wet-like cleansing wipes, which are dry until used, where fluid is released from the article. These articles comprise: a. a carrier comprising a cellulosic fibrous structure having at least a first region of relatively high basis weight that comprises an essentially continuous network and a second region of a plurality of mutually discrete regions of relatively low basis weight which are circumscribed by the high basis weight first region; and b. an emulsion applied to the carrier, where the emulsion provides fluid for cleaning when shear forces are applied to the article. The first and second regions of the cellulosic fibrous structure are disposed in a nonrandom, repeating pattern. The articles offer a number of significant advantages over prior cleaning products when in the form of wet-like cleansing wipes such as those used for cleaning of hardsurfaces (e.g., floors, countertops, sinks, bathtubs, toilets, and the like). The inclusion of low basis weight regions avoids substantial fluid retention by the cellulosic fibrous substrate, which allows fluid delivery to the surface being cleaned. The articles can be used in many applications requiring the delivery of polar materials, in particular water and water-soluble or dispersible actives. These include toilet tissue, wipes for personal cleansing, such as baby wipes, as well as those for the delivery of water-soluble or dispersible antimicrobials or pharmaceutical actives.
