Synergy for wiping surfaces
TECHNICAL FIELD * This invention is generally related to surface absorbent wipers, in particular | * with wipers having an outer layer of compression and an absorbent core. More particularly, this invention relates to semi-unobtrusive purpose devices that are capable of effectively drying a surface or other objects.
Surface wiping utensils are those used to remove spilled liquids or other accumulation of moisture from a surface such as walls, tables, floors, windows, bar stools, or other surfaces.

-2 items such as kitchen utensils, cutlery and the like. Surface wipers can be durable (ie used for a long time as sponges and dishwashers) unobtrusive (that is, for single use, such as paper towels) and semi-unobtrusive (where used for a longer time). ).
% Durable or limited-use surface wipers are reused and can be saturated with a humidifier, squeezed and reabsorbed a large amount of humidifier when reused. Pressure is usually achieved by pressing with the hands or by twisting the tool. In addition, the wiping tools can have a spherical (i.e., one layer) structure in layers (i.e. eg two or more layers, having at least one interface), in thin sheets (i.e. two or more layers with at least adherence), or they may consist of a combination of structure in layers and sheets.
Regardless of the structure, when used in the old art constructions to remove a liquid accumulation, it is difficult to completely dry or wipe the surface. In general, the prior art constructs rapidly absorb large accumulations of liquid from one surface to another without being able to absorb a sufficiently large amount of liquid, which is left on the surface in the form of small droplets.
These small droplets leave the surface wet and as they evaporate they may stain or leave a lump on the surface.

Background technique
Examples of non-vacuum sweepers of interest are US RATEN 5; 577; 645 U.S. J. TEHG et al., April 16, 1968; US Patent 5,689,797; January 1892. However, these utensils do not have aspects of this invention, where a surface wicking utensil has a core that absorbs the largest drops of liquid and an outer layer, which are incompressible and whose gaps are attenuated. * The combined action of the core and the outer layer removes liquids from the wiped surface and prevents new compression, under normal wiping pressure, from being wet on the surface. * This surface therefore dries perfectly. * The surface or surface is considered to be really dry when the surface remaining on the surface is in the form of very small droplets, which evaporate to less than 15 sec. without soiling, staining, or coating a film on the surface.
It is therefore an object of our invention to provide a virus wiping device capable of completely drying a surface.
An additional object of our invention is to provide a wiping surface having an absorbent core and an outer compressible layer.
It is a further object of our invention to provide an outer layer wiping device having an outer layer with a combination of characteristic. and retains the secondary drops of liquid.
These and other objects of this invention will become apparent when examined in connection with the following description and claims and in connection with the accompanying drawings.
Content of the Invention
According to the present invention, a wiping device apparently has an absorbent core enclosed in an outer layer, uncompressed. The physical characteristics of the outer layer facilitate the rapid passage of the primary water droplets while retaining the secondary droplets. The primary liquid drops are those accumulations, the peaks of which reach the adsorbent core, thereby forming a continuous liquid between the absorbent core and the base of the accumulator liquid. The formation of such a continuum results in the rapid transfer of the primary drop of liquid into the absorbent core. The base of the large drop of liquefied petroleum may be coated with a surface that is wiped or may be in the clearances of the outer layer.
Secondary drops are accumulations of acne which do not form an absorbent core with other ulcers and are held in the outer layer gaps.
By removing the primary and secondary drops of liquid from a surface, the sweeping device

-5 really dry. A surface is really dry when the surface that remains on the surface is in the form of very small droplets that evaporate in less than 15 seconds without staining, staining or leaving a membrane on the surface. These droplets are not primary (do not touch the surface of the core) or secondary droplets (are not attracted to the outer layer gaps).
* The ability of the surface wiping tool to effectively dry a surface is expressed by the outer layer liquid removal index; Is it possible for the outer layer to effectively dry a surface e.g. as the thickness of the outer layer increases, the ability to form a continuous liquid between the surface being wiped and the absorbent core decreases, with a high degree of porosity increasing the ease with which the outer surface is formed; returning to the absorbent core to come into contact and reclaim the wiped surface. In addition, an outer layer with an open, porous structure may not have sufficient capillary traction space to attract and retain secondary liquid droplets. But a closed non-foam surface will act as a barrier for liquid, preventing the flow of liquid between the absorbent core and the wiping surface. In addition, an outer layer that is very close to the liquid will saturate and place liquid again on the wiping surface.

Better way of applying the invention
With reference to Fig. I, we are now contemplating a preferred embodiment of our invention as shown in Fig. I. The surface wicking tool of our invention is a leaf structure comprising an outer layer 12 and an absorbent layer 12.
The surface coating tool 10 can be manufactured in a wide variety of shapes and dimensions.

Preferably, the surface wiping device 10 has a rectangular shape, approximately II I 9 inches (28 x 23 cm). In addition, the wicking tool 10 may have a laminate, laminate or laminate structure and a laminate, as described above.
* The absorbent core 14 may be any absorbent material capable of absorbing an ICO of at least 25 g of absorbent water, as defined by the methodology;
The rectangular rectangular apparatus with a base of 4 14 inches (10 l 10 cm) is charged with 25 g of absorbent material and weighed. * The device is filled with excess water or left to run through the holes in the base of the device. * The apparatus is re-weighed or the difference directly in the starting weight and the final weight of the apparatus is the excess absorbed.
<sup>, B.</sup>Furthermore, the absorbent core material must be able to disperse the liquids by dissolving the absorbent liquids in the absorbent core 14. * The rate of dispersion of the absorbent core material has an important effect on the heat transfer rate. effectively dry a surface. * The rate of dispersion of the sorbent core can be determined by the sequential methodology. * A rectangular rectangular plate based on I.5.5 Tcs (2.5 C 12.7 cm) is charged with 0.45 gm of absorbent core material, evenly distributed evenly with uniform thickness.

Inches (12.7 kg). The water is essentially at zero pressure when it is in contact with the absorbent fluid. To be satisfactory, the material of the absorbent core must transfer the water at a length of 5 inches (12.7 cm) to less than 60 seconds and preferably less than 30 seconds.
In addition, the absorbent core 14 must be capable of absorbing liquids, absorbing more or less of the absorbed liquid when it is compressed by hand, and still capable of absorbing additional liquid, being readily available. * This ability to absorb moisture after squeezing is especially important when the amount of moisture to be absorbed by a surface is greater than the amount that the sorbent core 14 can absorb.
As used herein, Dr * gr refers to water and aqueous solutions.
Preferably, the absorbent core is soft and flexible, adapting to the surface to be wiped. Another desirable, Sv, and not an essential feature of the absorbent core 14 is high and strong and dry. Examples of materials suitable for use as absorbent cores 14 are natural sponges, foam polyesters, bulk polyurethane, cellulose, and absorbent devices made of synthetic fibers such as glass or fiberglass. For the preferred embodiment, a foamy hydrophilic polyurethane is used. leaf form and can be used

The outer layer 12 overlaps at least one outer surface absorbent core 14 and preferably encloses and comes in close contact with the absorbent core 14, forming an intermediate layer 20. * The outer layer is compressible, compressible surface drying agent 10, immediately takes on the surface-melt form which is wiped and additionally has surfaces for wiping 18 (one is shown in FIG. I) where rubbing on the surface (not shown in Fig. I) where to dry. In the preferred embodiment, the outer layer 12 extends first through the wiping surface 18 of the surface wiping tool 10, to the middle surface 20.
As used herein, compressed wood is absent in the outer layers 12, having a thickness loss of less than 45%. * Thickness loss is determined by a sequential equation.

A wide variety of materials and techniques for making the outer layer 12 e.g. the outer layer 12 may be made of natural fibers, such as raw silk, synthetic fibers, such as polypropylene, or non-thermoplastic materials such as polyethylene; - or the outer layer 12 may be woven, woven, non-woven, aps of a thermoplastic layer. Preferably the outer layer 12 is a non-woven fabric made of polypropylene fibers.
* The outer layer 12 and the absorbent core 14 can be combined by using any of the methods known in the art. E.g. or the outer layer 12 may be made in the form of a pocket, whereby the free end may be closed by any suitable method, such as sewing, ultrasonic fusion or welding. In the preferred embodiment or fusion with ultrasound, as is known in the art, it has been used for welding the outer layer 12.
XX. 2 We now see that the outer layer is non-compressible and must have a combination of thick porous and characteristic fastenings, which facilitate rapid transport of the primary drop 15, retain and drop at 15, and not to allow the absorbent core / recess on the surface 17 to be wiped.

However, the outer layer 12 should not have pores large enough for the absorbent core 14 to rest on the wiping surface.
The glass support containing the sample is inserted into a slide projector and projected onto a classic screen. While any classical headlamp can be used, EKTAGRAPHIC MODEL AR2 was used as manufactured by KODAK CORPORATION OF ROCHESTER, NT, with satisfactory results. * The projector is aimed at the center of the lounge and is positioned at a distance of 118 inches (500 cm) perpendicular to the lounge. * The headlamp is centrally positioned above the ounces and displaced almost centrally to the center of the table at a distance of about 29 inches (74 cm) from the center of the table.

Material samples made from the outer layer 12 will give indications of O to IO, which will indicate the percentage of layer 12, which is open to passage.
The percentage of open area is converted to a fraction to be used in the calculus for the removal index of gpC.

The method of determining the index of porosity other than those described herein may be used by those skilled in the art. These other methods can be used as long as they represent the open areas of the wash material used in the manufacture of the outer layer 12.
The thickness of the sample was determined at a pressure of 0.175 l / s. tv. (1.21 KP) and can be measured using known methods. E.g. a standard spacer may be used. * A suitable spacer is manufactured from TESTIHG MACHINES INC. Of AMTYTTT, NI and sold under the name PRECISION MICROMETER SERIES 400 TESTER MODEL 449-27-3. The thickness is determined by a carrier of 0,175 l / min. tv. (1.21 KP), to ensure that the indicator does not deform by a percentage of projections.
The protrusions that are retained by the outer layer can also be determined using simple methods, e.g. two absorbent cores with a wiping surface of 7 pcs. and which absorb at least 55 g. Liquid and wash have a diffusion rate of 50 sec as described in the methods described above, weighing rapidly and both ends are wrapped in a square 8 inch (20 cm) outer layer 12 with a surface of 4-9 cm. from. in contact with the surface to be wiped.

17.
The accumulations of liquor 16 deform as the liquor enters the voids of the outer layer 12, without touching the absorbent core 14, forming a primary drop 15 to flow into the absorbent core 14, as well.
The percentage of two precursor droplets 15 which are absorbed by the absorbent core 14 will form either secondary drops 15, which will drop and retain clearances II or smaller droplets (where they are 17). 15 sec without staining or dazzling them. In addition, the secondary drops 15 can accumulate in gaps II and form primary drops 15 as the wiping continues.
It is to be understood that the foregoing description corresponds to the preferred embodiment of the invention and is therefore merely representative. There are obviously many variations and modifications of this invention, according to the foregoing teachings. As shown in Fig. 5 e.g. the surface wetting tool IC may be enclosed in a cover 22, which is a laminate covering which surrounds the absorbent core 14.;
The laminate cover 22 has an outer layer 12 and an inner layer 24, which are connected to the joint.
<img file="GR65611B_D0023.tif" />
L.
26. The outer layer 12 extends from the wiping surface 18 to the coupling 26 between the outer 12 and the inner layer 24. The liquid removal index (LRI) of the outer layer. 12 is determined by cutting the cover 22 along the joint 26 to separate outer layer 12 from inner layer 24. * The outer layer 12 may undergo the test procedure described above. Leaf structure as used herein can be achieved in all known ways. E.g. can be achieved by thermo-welding or by forming a single layer over another. In addition, the joint 26 may be an intermittent or continuous welding directly between the various layers.
Alternatively, the surface cleaning tool 10 may be layered. That is, the absorbent core 14 and the outer layer 12 face are welded as shown throughout the assembly in Fig. 4.
In this case, the outer layer 12 extends beyond the wiping surface 18 to the joint 28. To determine the liquid removal index (LRI) of the outer layer 12 in this application, or the outer layer 12 is separated from the outer layer 14 length of joining 28 and is subject to the test described above. In another embodiment or outer layer 12 it may be welded to a stopper in the core 14.
In addition, the surface wicking tool 10 may have a layered structure as shown in Fig. 5, with an intermediate layer 30 between the outer layer 12 and the absorbent core 14. * The outer layer 12 is applied thereto. the wiping surface 18 and the interface 52 with an intermediate layer 30. * 0 -24- liquid removal index (LRI) of the outer layer 12 in this application is determined by separating the outer layer 12 from the intermediate layer 20 along the interface 52 and removing the outer layer 12 at the outermost layer 12. * The intermediate layer 5i can serve a variety of purposes, such as to provide additional tensile strength to the instrument 10 or to improve lateral diffusion of the liquid passing through the outer layer 12 through the outer layer 50. Improvement of diffusion is a material manufactured by fusion of processed polypropylene fibers to have high surface activity. A suitable surface active material is manufactured by TEXTILANS CORPORATION OF HAWTHORNS, CALIFORNIA and has the trademark VELVETS! BCW.
In addition, the surface wicking tool 10 may have a plurality of compartments 54, as shown in Fig. 6. The compartments 54- contain an absorbent core 14, comprising a non-absorbent foam material.
The compartments 54 can be constructed so that they are or may be remotely touched as shown in Fig. 6 and they are connected to a joint 56 forming an outer layer 12.
* The connector 56 may be such that it adds flexibility to the tool 10 and can be constructed by squeezing the outer layer 12 so that the compartments 54 are independent of each other (i.e. not touched).
