pressure. Very large amounts of water may therefore be stored in
the punched nonwoven without its surface feeling particularly
wet” (col. 2, lines 52-57). The portion of the latex foam layer
extending below the nonwoven fabric layer “has particularly soft,
resilient properties and is permeated by countless interconnected
open pores. These communicate hydraulically with the fibers of
the needled nonwoven, thus resulting in a pronounced water-
absorption effect” (col. 2, lines 33-37). That portion of the
latex foam layer has spongelike absorbency (col. 2, lines 47-48)
and “communicates with the top surface in a manner enhancing the
suction effect. This enhanced suction effect is due on the one
hand to the storage capacity of the needled nonwoven, which is
largely independent of the external use of pressure, and on the
other hand to the fast rate at which the open-pore foamed-plastic
layer is able to take up liquid or give it up to the nonwoven”
(col. 3, lines 27-36). The cleaning cloth “lends itself well to
the drying of windows and cars, tiles, wash basins, dishes, etc.”
(col. 2, lines 41-42).
Schoonen discloses tack cloths for removing “dust and the
like particulate matter from metal or other surfaces which are
about to be painted or otherwise finished” (page 1, lines 6-8)
and which “also find use in the home, where they are often
referred to as dust cloths, to remove dust or lint from various
