Said structure is formed of layered sheets, bonded to one another, including a thin sheet of a cellular material the face(s) of which have a very thin sheet-like overlay of a non-woven permeable reinforcing material such as, preferably, rayon or nylon. The body of the cellular sheet material, preferably of plastic such as polyurethane, polyester or polyether, is characterized by innumerable extremely small, relatively minute pockets having extremely thin elastic wall portions through which fluid may readily pass to said pockets to store therein in amounts the volume of which may be a significant multiple of that originally defined by said wall portions. Exmbodiments of such sheet-like structure are formed and conditioned to readily filter, pass or store fluid and substantially fully release fluid stored therein when under the influence of a moderate application of pressure. When the fluid is a liquid the extent and speed of its release insures a quick drying of this material. An illustrative demonstration of the invention comprises a short length of said sheet-like structure having multiple slits portions of which define lines upon which it can be quickly folded on itself and produce a layered mop which is extremely light in weight and even more effective in application to its intended use than the original form of said sheet-like structure.Field of SearchHaving strandsWith fixed handle And cloth sheath type head Sponge or sponge with holder Sponge Plural spaced surface engaging edges Noncircular aperture (e.g., slit, diamond, rectangular, etc.) Slit or elongated Pleats or otherwise parallel adjacent folds Composite having voids in a component (e.g., porous, cellular, etc.) Plural void-containing components With component specified as adhesive or bonding agent Composition of adhesive or bonding component specified | |
