A counterintuitive sandwich cloth.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to rapid and efficient cleaning tool and more particularly to cleaning cloths and paper towels.

2. Description of Related Art

Various cleaning cloths have been disclosed in the prior art as being useful for wiping off dirt and grime, to clean, and polish. These textiles have absorbent wet or dry dirt/grime pickup surfaces. The focus of the multi-million dollar industry is on increasing absorbency properties. They have spent much time and dollars on microfiber technology, which brought about amazing absorbent power, illustrated in ShamWow™ infomercials.

Rags, cloths, paper towels, textiles are used to wipe off dirty surfaces, such as kitchen counter-tops, floors, desks, hands, or body after shower, and cars. Textiles are used for dusting, polishing, or drying off wet surfaces. Textiles are used in laboratories, factories, or car repair shops to wipe off grease, oils, or chemicals.

Hale, U.S. Pat. No. 5,918,341 describes a revolutionary advance in the application of surface pattern folding guide map applied to a cleaning device to shorten cleaning time, and simplify the cleaning process. It imbeds cleaning technology professionalism of maids and janitors into the hands of untrained consumers. In seconds, the untrained consumers immediately apply the speed and thoroughness of professionals of an excellent cleaning job well done.

3. Revolutionary Breakthrough Nature of New Invention

Historically, when people think of cleaning fluids or water off a surface, they think of absorbing. This invention surpasses all prior absorbent cleaning textiles by using the counter-intuitive built-in waterproof layer. The water repelling or fluid barrier as a cleaning material common sense-ly seems like it would not work to clean dirty surfaces.

Instant invention contains layered fluid barrier and absorbent material as cleaning device. The device contains a layer or lamina absorbent and a fluid repellent or vapor barrier. The concept is the counterbalancing action of repelling and absorbing fluid.

The cleaning device has counterbalancing actions of repelling and absorbing moisture, fluids, vapor, and water.

The invention has dually opposite paradox co-existing inside one device.

The cleaning device works like a transistor that revolutionized electronic technology. Similar concept is opposite pairing, or coupling, like male and female.

The vapor barrier allows small portions of the material to be used without soiling the remainder of the material. Further, by demarcating hand-sized portions of the material and even by numbering those portions, a relatively large number of uses are permitted while avoiding the un-intentioned soiling of the remaining material.

Textile as a word is used herein to include cloth, felted sheet preferably made from vegetable fiber commonly known as paper, paper towels, toilet paper, and cleaning wipes.

A paper towel is a tissue paper made from absorbent paper rather than cloth. Unlike cloth towels, paper towels are disposable and intended to be used only once. Paper towels can be individually packed (as stacks of folded towels) or held on a continuous roll.

Paper towels have almost the same purposes as conventional towels, such as drying hands, wiping windows, dusting and cleaning up spills. They are most commonly known for being used in kitchen work. Because paper towels are disposable, they are often chosen to avoid the spreading of germs. Paper towels have a heavier environmental impact than conventional cloth towels, because they are not intended to be used more than once.

Paper towels are made from paper pulp. Resin size is used to improve the wet strength. Patterns of shapes such as circles or diamonds are often imprinted into the paper towels to help it hold moisture. Manufacturers use the pattern of the material, microscopic spaces within the pattern, and a type of cellulose in the fibers in order to maximize absorption. Most rolls are manufactured with two layers of thin paper, but different types can have more or fewer layers. Paper towels are made from paper pulp, which is extracted from wood or fiber crops. It was first made by Arthur Scott out of a cartload full of rejected toilet paper! He perforated them into small towel-size sheets and sold them as the first ever disposable paper towels. Scott was again the first to introduce the paper towel for kitchens in 1931. It was thirteen inches wide and eighteen inches long. Tissue paper is lightweight, and made of multiple layers for better absorption. They are classified as per their key properties such as strength, absorbency, weight, and thickness. They have to be disposed, after just one use. Paper towels are packed individually and sold as stacks, or are held on a continuous roll. There are patterns and shapes often imprinted into the paper towels to maximize absorption. Most paper towels are manufactured with two to three layers of thin paper, but some types can have fewer layers.

The absorbent material preferably made of microfiber textile. One example is ShamWow™. Terrycloth can also be used.

When the absorbent capacity limit of textile is breached, or even significantly before breaching, due to capillary action, the fluid or liquid reaches the backside of the textile and comes into contact with your hand. This may be undesirable from the point of view of a fastidious housewife, a doctor cleaning up contaminated fluids, a janitor cleaning the bathroom.

Hereinafter referred to as “cleaning sandwich”. The present invention improves on the prior art in providing these benefits.

Instead of a simple textile like cloth or paper towel, my invention provides a sandwich of opposing materials. One layer is hygroscopic/hydrophilic material, and another layer is hydrophobic material. The one of the layers in the sandwich of materials is a liquid proof or waterproof or fluid proof layer. Fluidphylic and fluidphobic materials are used in layers to create the invention. Preferably, fluid resistant, water proof, or water repellant, or moisture bather material such as waxed paper, plastic sheeting, tarpaulin, treated canvass, or coated textiles are used.

Single layer or multiple layers can be used to create the invention.

General prior art discloses flexible planar cloths found in supermarkets and auto parts stores, for example. This produces a mixed result. Although designed to affect dirty surfaces, there are several limitations to this approach. First, planar cloth arrangement is designed to affect dirty area. My invention is designed to affect areas, and to keep it clean.

Secondly, planar cloth arrangement is designed for wipe once. My invention is arranged such that multiple wipes are accomplished, while keeping surfaces clean. This presents unified professional trained janitorial approach.

Thirdly, for manufacturing purposes, my invention preferably consists of a rectangular area upon which repeating patterns can be expanded to cover larger and larger area. This makes ease of scalability, and ease of manufacturing. A rectangle is preferred geometric shape; although another other geometric shape can be utilized. Other embodiments can be imagined such as squares and triangles.

One example of a use would be for cleaning windows or mirrors. One side of the device could be kept wet with window washing fluid and the opposite side of the device would be kept dry for drying the surface of the window or mirror.

The sandwich can be made of disposable and/or biodegradable materials.

Fourthly, my invention eliminates or reduces excess trips to clean the cloth during the cleaning time.

Fifthly, my invention additionally utilizes double sided surfaces. One specific surface is water resistant thin material. When stimulated under specific conditions, the material resists the dirty fluid that has been absorbed into the hydrophilic layer.

Sixthly, the water resistant material, are combined with absorbent material to become more effective cleaning agents. Shamwow, again, is a preferred substance that super absorbs fluids. More information on super absorbents can be googled.

My invention is rapid acting promoting cleaning device in which objective measurement of said improvement is obtained. Improvement occurs within seconds of using my invention.

The absorbent textile, preferably made of cloth or paper, are from a class of materials such as wood pulp, cotton fibers, or artificial fibers.

The cleaning device is preferably made hand-sized. Other embodiments are larger or smaller sizes. For example, a larger size could be 6 feet by 9 feet. A smaller size could be 2 inches by 2 inches.

In addition to the fluidphoboic lamina as barrier protectant to the hand, the foldable layers provide additional thickness as additional protective barrier. The protection serve a role in case of contaminated or toxic fluids spill, or as temperature control in case of hot stove or radiator, or cold solids or fluids, such as ice, dry ice, or liquid nitrogen.

In cleaning, the dirt or contaminated fluid folds into the panel sections, to prevent cross-contamination into clean panels.

BACKGROUND OF THE INVENTION

An important component of disposable absorbent articles such as diapers is an absorbent core structure comprising water-swellable polymers, typically hydrogel-forming water-swellable polymers, also referred to as absorbent gelling material, AGM, or super-absorbent polymers, or SAP's. This polymer material ensures that large amounts of bodily fluids, industrial fluids, lab fluids, household fluids can be absorbed by the article during its use and locked away, thus providing low rewet and good skin dryness.

SUMMARY OF INVENTION

It is, therefore, an object of the invention to easily create a scaleable mapguideable use once cleaning device that absorbs dirty fluids without transmitting said fluid into other parts of the cleaning device.

It is, therefore, an object of the invention to provide a guide for non-experts (consumers) in the art of cleaning surfaces professionally, thoroughly, quickly, and easily.

Another object is to provide a dual-purpose cleaning device that both provides for applying and/or removing moisture or liquid matter from surfaces, AND simultaneously provide a dry material to dry off surfaces.

Another object is to create a professional janitorial speed, effectiveness, and clean surfaces in brief time.

Another object is to raise the “clean level” status inbetween cleanings.

Another object is as an easily disposal convenient cleaning device.

Another object is to prevent cross-contamination.

Water-Swellable Material, Hydrogel Forming Polymers

The water-swellable material of the invention is such that it swells in water by absorbing the water, thereby forming a hydrogel. It may also absorb other liquids and swell. Thus, when used herein, ‘water-swellable’ means that the material swells at least in water, but typically also in other liquids or solutions.

The coating agent is preferably hydrophilic and in particular surface hydrophilic. The surface hydrophilicity may be determined by methods known to those skilled in the art. In a preferred execution, the hydrophilic coating agents or elastomeric polymeric materials are materials that are wetted by the liquid that is to be absorbed. They may be characterized by a contact angle that is less than 90 degrees. Contact angles can for example be measured with the Video-based contact angle measurement device, Kruss G10-G1041, available from Kruess, Germany or by other methods known in the art.

Special purpose sandwiches for a particular liquid commonly spilled in particular industries, home, auto mechanic shops, and laboratories for example.

It may also be preferred that the resulting water-swellable material or coated hydrogel forming polymer particles are hydrophilic. This hydrophilicity may be measured as described in co-pending U.S. patent application Ser. No. 14/331,030.

The hydrophilicity boosting compositions of the present invention may also include optional ingredients such as, a carrier, surfactant and other adjunct ingredients. Suitable carriers include liquids, solids and gases. One preferred carrier is water, which can be distilled, deionized, or tap water. Water is valuable due to its low cost, availability, safety, and compatibility.

Optionally, in addition to or in place of water, the carrier can comprise a low molecular weight organic solvent.

Surfactants are especially useful in the coating composition as wetting agents to facilitate the dispersion of nanoparticles onto the substrate. Surfactants are preferably included when the coating composition is used to treat a hydrophobic substrate.

Preferred (Disposable) Absorbent Articles and Structures

The absorbent structure of one embodiment of the invention is typically for use in disposable absorbent articles, such as preferably interlabial products, sanitary napkins, panty liners, and preferably adult incontinent products, baby diapers, nappies and training pants.

Preferred disposable absorbent article herein are sanitary napkins, panty liners, adult incontinence products and infant diapers or training or pull-on pants, whereby articles that serve to absorb spilled liquids, e.g., adult incontinence products, diapers and training pants are most preferred articles herein.

Preferred articles herein have a topsheet and a backsheet, which each have a front region, back region, and fluid barrier positioned herein between. The hydrophobic structure of the invention is typically positioned in between the topsheet and backsheet. Preferred backsheets are vapour pervious but liquid impervious. Preferred topsheet materials are at least partially hydrophilic; preferred are also so-called apertured topsheets. Preferred also that material is ShamWow™.

These preferred absorbent articles typically comprise a liquid impervious (but preferably gas or water vapor pervious) backsheet, a fluid pervious topsheet joined to, or otherwise associated with the backsheet, and the absorbent structure according to the present invention positioned between the backsheet and the topsheet. Such articles are well known in the art and fully disclosed in various documents mentioned throughout the description, e.g., in EP 752 832.
