Description:
MULTI SURFACED CLEANING CLOTH FIELD AND BACKGROUND OF THE INVENTION This invention relates generally to a cleaning cloth for the damp or dry cleaning of surfaces.

There are a variety of cleaning cloths known in the art, for example, there are abrasive steel wool pads, consisting of a bundle of metal fibers.

Some of those pads are impregnated with soap or with a mixture of soap, detergent, sodium carbonate, perfume and dye. Also, the wet steel wool pads rust and deteriorate within one to two days from the time they are initially used. Consequently, because they quickly lose their cleaning ingredients and rust badly, a steel wool pad can only be used once or twice and thrown away.

Another form of cleaning cloth is a scouring pad. A variety of materials are attached to, or integrally formed with, a sponge or foam pad.

An example of such a scouring pad such as is disclosed in U. S. Pat.

No. 3, 080, 688 and consists of a layer of the adhesive and abrasive treated fiber batt, noted immediately above, laminated to a layer of cellulose sponge which had been impregnated with a detergent solution.

A further type of scouring pad known in the art is disclosed in U. S.

Pat. No. 3,641, 610 and consists of a cellulose sponge with tufts of synthetic strands imbedded in its thickness spaced about 1/2"apart and extending above one surface of the sponge to serve as scrubbing bristles.

All such scouring pads known have shortcomings and disadvantages.

None of the pads can be used as floor cloths, dish cloths, mops and the like.

An example of a cleaning cloth is described in WO 90/14039 (the contents of which are incorporated herein by reference). A textile base layer made of non-woven fibers has a plurality of filament loops, on the cleaning surface, which project from this surface. The loops are obtained by needle- tufting the textile base layer, and are brought together to form surface regions, which run along alternating regions of the cloth.

These surface areas are separated by lines, which extend across the entire cloth and are structured in the form of depressions. These lines are essentially free of projecting filament loops and are formed by the filament or fiber material of the textile base layer.

These depressed lines do not run linearly, but rather extend in a curved or wavy shape, which not only reduces the frictional resistance of the cloth on the surface to be cleaned, but also provides that accumulations of dirt are immediately picked up when the cloth is wiped over the surface.

Since the transitions between the looped regions and the continuous lines which separate the looped regions from one another constantly change direction over their course, not only does a vertically directed pressure (relative to the wiping direction) act on the dirt particles, but in addition, a wiping force effect at an angle occurs, which causes the dirt to move across the channels. This reduces the risk that dirt particles which have become fixed in place in the region with the loops will come loose again.

At least one of the areas which has loops must extend continuously

from one end of the cloth to the other. Preferably, however, all the areas which have filament loops and all of the low-lying channels free of loops run continuously in the lengthwise direction of the cloth.

The filament loop areas and the lines between them can consist of the same or different textile material, such as natural, regenerated and synthetic fibers, which can be anti-static, treated to be anti-static or treated with substances which promote cleaning.

Numerous methods are suitable for production of these known cloths.

The preferred method of production is one which is generally analogous to that used for the production of a terry cloth, where the starting material is a woven base surface.

The projecting loops described in WO 90/14039 can also be cut, so that the fiber bundles project from the raised surfaces at their ends. In each case, there are surface regions which stretch out lengthwise, and extend continuously at least partially over the entire cleaning cloth.

All such cleaning cloths known have shortcomings and disadvantages. None of the cleaning cloths can be used as a floor cloth and when needed as a scourer or scrubber. None of the cleaning cloths can be used as a dish cloth and when needed as a scourer or scrubber to remove dirt and grime and thereafter to be used as a dish cloth. None of the cleaning cloths can be used in strips as components of a mop for readily facilitating regularly mopping and alternate scrubbing and deep cleaning.

Furthermore, it is then necessary to ensure that the non-wiping surface

of the cloth contains a majority of the fibers which later form the loops, prior to the formation of the loops. Such a prerequisite is both costly and inconvenient.

Therefore, there is an umnet need for, and it would be highly useful to have, a combination cleaning cloth which includes both a cleaning surface and a wiping surface such that a single cleaning cloth can be used alternately to wipe, scrub, scour and/or be used as a floor cloth, a dish cloth, a mop and the like.
