Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to the field of cleaning and, in particular, to the scraping of common household articles such as aluminum, Teflon, acrylic plastic, porcelain and other common surfaces found in kitchens and kitchenware. An improved cleaning article that eliminates or substantially reduces scratches.

[0002]

BACKGROUND OF THE INVENTION Cleaning and cleaning articles typically include a natural or synthetic sponge, such as a natural or synthetic sponge, that laminates or adheres to one surface a scrim that may include an abrasive material. Consists of a porous material that absorbs soft water. The present invention describes a cleaning article that has a greater ability to remove dirt from a surface than a sponge, but does not scratch the surface when using other abrasive articles containing abrasive materials. Many of the abrasive surfaces of commercially available cleaning articles consist of a nonwoven synthetic fiber scrim bonded to a finely divided hard abrasive such as carborundum, alumina or silica. Other softer abrasives include calcium carbonate, talc and synthetic resins. A common method for depositing abrasives on nonwoven surfaces is to spray the abrasive with the abrasive in the resin formulation, whereby the amount, nature and depth of penetration of the abrasive into the fiber pad Thus, the abrasiveness of the nonwoven fiber can be adjusted. However, a problem with such scrims is that mineral abrasives can damage the surface being cleaned, as the mineral can be harder than surfaces such as aluminum, teflon and plastic.

[0003] Fabric scrims, on the other hand, are not very bulky and do not have randomly projecting fibers that can suitably provide a scaffold for a cleaning surface. Furthermore, the bottom surface of the textile material facing the sponge is also not bulky, which makes it difficult to adhere to the sponge layer by implantation in a soft sponge.

[0004]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to comprise an absorbent porous material and a textile substrate and pile fibers woven into the textile substrate, whereby the bottom surface of the textile substrate is reduced. It is an object of the present invention to provide an absorbent cleaning article including a scrim adhered to one surface of an absorbent porous body, which is adhered to the absorbent body by embedding in an adhesive or an absorbent body. In another embodiment, a woven yarn, such as cotton or rayon, is formed into a textile base such that a fiber loop is formed at the bottom of the textile substrate and the fiber loop is embedded in the absorbent to secure the textile substrate to the absorbent. It is woven into wood. The fiber loop can be cured with starch or other water-soluble curing agents for bonding or embedding.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In accordance with the present invention, a cleaning surface is provided on an absorbent material such as a sponge or fabric of a regenerated cellulose roll by bonding a fabric scrim to at least one surface. Woven scrims are typically about 45
A textile substrate in which pile fibers are woven so as to be at a predetermined angle with respect to the substrate surface between 0 ° and 90 °. The pile fibers appear as piles protruding from the substrate on one surface of the textile substrate, hereinafter described as the upper surface, to form a cleaning surface.

FIG. 1 illustrates a method for making a woven substrate having woven fibers as described above. In FIG. 1A, two textile substrates 10 and 11 are held parallel to each other, forming a pile so that a loop 13 is formed on one surface of each of the textile substrates 10 and 11, respectively. The pile fibers 12 are shown woven into the textile substrate layers 10 and 11. Textile substrates 10 and 11
The length X of the hard pile fibers 12 between is approximately twice the desired pile fiber height in the final product. X so that the pile length is 1 inch or less
Is typically about 2 inches or less.

[0007] By cutting the pile fibers 12 between the woven fabric substrates 10 and 11 so that they are plane-parallel and substantially equidistant,
Two fabric layers, one of which is shown in FIG. 1B, are formed with pile fibers 14 held on one surface by a fabric substrate 11. Although only one of the fabric layers is shown in FIG. 1B, it is understood that a second fabric substrate corresponding to fabric substrate 10 is also formed at the same time that pile fibers 12 are cut. Would. The textile substrate 11 is then adhered to an absorbent such as a sponge 15 by an adhesive forming an adhesive layer 16, as shown in FIG. 1C. Adhesives which can be used are those known in the prior art. For example, a polyurethane two-component adhesive covering the surface of the sponge can be utilized. Adhesives are known in the prior art, for example, the Holstered Press sounder,
K. J. Chapter 14 of the book Organic Polymer Chemistr (197
3), especially on pages 318-345.

[0008] Unless it bonds well to adhesive surfaces, such as wet sponges and textile materials, and does not become hard enough to reduce the flexibility of the article, or does not substantially impede the permeation of liquids. Other types of adhesives can be used, for example.

FIG. 2 shows a schematic diagram of another embodiment in which the fabric layer has been modified to adhere directly to the sponge without an adhesive. The first material of the double fabric layer in FIG. 2A is made by weaving the yarn forming fiber loops 17 extending from the fabric substrates 10 and 11 to form the fabric substrate.
Same as the material shown in FIG. 1A, except that 10 and 11 are modified. These fiber loops 17 extend beyond the loops 13 formed by pile fibers so as to form a better means of bonding the textile substrates 10 and 11 to the sponge. Fiber loop 17 may be cured with starch or other water-soluble curing agent to secure the loop during processing. The starch is later dissolved during use of the article or during regeneration of the sponge. FIG. 2B shows the fabric substrate 10
One of the scrims formed by cutting the pile fibers 12 so that they are plane-parallel to and 11 and are approximately equidistant between the textile substrates is shown. FIG. 2C shows that the fiber loops 17 are embedded in the viscous cellulosic material 19 before the material is regenerated to a solid form by the process shown in FIG. 2D.

[0010] An alternative method of bonding the scrim to the absorbent to provide a voided or bulky polyurethane foam surface to the sponge material is to apply, for example, a polyurethane foam coating to the bottom of the textile substrate 11. Spraying or bonding can be included. The polyurethane foam is then embedded in the viscous cellulose and the sponge regenerated as described in connection with FIG. Alternatively,
The polyurethane foam coating can also be adhered to the sponge as described in connection with FIG.

In yet another embodiment, instead of the fiber loop 17 shown in FIG. 2, the textile substrate 11 may be sewn or adhered to fibers having a bulky surface, such as terry cloth. Can be glued. The terry cloth is then embedded in viscous cellulose, as described in connection with FIG. 2, or adhered to a sponge, as described in connection with FIG.

[0012] Methods for regenerating cellulose to make porous sponges are known in the prior art. For example, a viscous cellulosic material can be formed by immersing a sheet of cellulose in an 18-1 / 2% (by weight) sodium hydroxide solution for a time sufficient to alkalify the cellulose. The resulting alkali cellulose is mixed with, for example, carbon disulfide, and the resulting mixture is stirred until cellulose xanthate is formed. The resulting cellulose xanthate is dissolved in a viscous cellulose weak sodium hydroxide solution, typically 5-7% of the weight of the cellulose, 5-6% of the alkalinity and about 2.3-2.6% of the total sulfur. % Viscous cellulose product. The pre-mature material preferably retains its mass at a temperature below about 15 ° C. for about 20 minutes,
It can be mixed with hemp fibers or other suitable reinforcing fibers, typically having an average length of about 3/8 to 1/2 inch.
To this material is added sodium sulfate decahydrate crystals having an average particle size according to the desired pore size of the finished sponge. Typically, an average particle size of about 10 millimeters of sodium sulfate dehydrate produces a relatively continuous pore product, and an average particle size of about 2 millimeters produces a relatively fine pore product. to make. This mixing lasts for a further approximately 10 minutes, keeping the temperature at or below 15 ° C. This material can then be deposited into a mold or form of any desired shape, preferably linearly set.

[0013] Alternatively, the material is deposited on a sheet or conveyor and topped to obtain the desired height of the sponge. The scrim can be implanted while still in this viscous state. The bottom side of the elongated scrim of the fiber loop 17 can be embedded in one surface of the uncured cellulose, which is then set and regenerated. This can be done by immersing the form in a boiling sodium sulfate solution and exposing it under high vapor pressure in an autoclave, or by passing a high current, preferably using AC, through the material. This is done by increasing the temperature of the substance. During the coagulation process, the sodium sulfate dehydrate crystals liquefy and flow out of the material, leaving the corresponding pores.

The coagulated cellulose sponge is washed with warm water to remove the remaining sodium sulfate decahydrate, and a sodium hydroxide solution is used.
Neutralized with a base such as ide solition) and bleached with an aqueous solution containing hypochlorite. The bleached block or sheet is then treated with warm oxalic acid and washed again to remove traces of the acid. The block or sheet is then sprayed with a wetting agent, such as glycerin, PEG, propylene glycol, urea or a mixture thereof, and dried to the desired moisture content. Antifungal agents such as quaternary ammonium compounds can be added to prevent the growth of mold on wet sponges.

Fabric substrates 10 and 11 and pile fibers 14
The material capable of forming is preferably polypropylene, but may be natural fibers (such as cotton) or synthetic fibers such as polypropylene, rayon and the like. Fine metal fibers such as stainless steel alloys can also be used.
The yarns of the textile substrates 10 and 11 are substantially pile fibers 14 at fixed positions at a predetermined angle with respect to the textile substrate.
And minimizes leakage through the non-regenerated viscous cellulose substrate when the opposite surface is partially embedded in the viscous material.

In embodiments where the fiber loops 17 are woven into the bottom surface of the textile substrates 10 and 11 or where an additional layer of fabric such as terry cloth is utilized as described above, these materials are Preferably, it consists of cotton, rayon or other material, which after implantation has a strong affinity for the regenerated sponge.

The final product shown in FIG. 3 comprises an absorbent body 15 having a textile substrate 11 adhered to at least one surface with pile fibers 14 projecting substantially vertically from the textile substrate 11. Consists of Depending on the method used to adhere the textile substrate 11 to the absorbent material 15, use of an adhesive layer (not shown) and / or additional layers (not shown) such as polyurethane foam or fiber cloth can do.

The following example is provided as a means of illustrating the invention.
