Patented Dec. 16, 1952 IMPREGNATED CLEANING PAD AND METHOD OF IMPREGNATIN G SAME John R. Fisher, Jr., Dayton, Ohio, assignor to International Steel Wool Corporation, Springfield, Ohio, a corporation of Ohio No Drawing. Application December 11, 1946, Serial No. 715,603
4 Claims. 1
This invention pertains to fibrous cleaning pads, and more particularly to detergent impregnated pads and the manner of incorporating the detergent material therein.
The instant cleaning pads may be of metallic wool, vegetable fibers such as hemp, cotton or analogous material, or may be of synthetic or artificially prepared fibrous material, which will have been permeated with soap or other detergent material.
The impregnation of metallic wool pads with soap compound has been long and well known. However an equally continuing and insistent problem has been that of increasing the life and period of usefulness of the soap or detergent content of such pads, and retarding its too rapid dispersion.
Such fibrous cleaning pads when impregnated with pure soaps or with soap compounds have a tendency to rapidly release the soap content thereof quite early in their period of use, thus leaving the fibrous pad empty which materially reduces the effective cleaning action thereof.
The object of the invention is to improve the character as well as the means and mode of manufacture and operation of fibrous cleaning pads impregnated with specially prepared soap or detergent material whereby the cleaning pad may not only .be economically manufactured, but will be more efficient in use, of increased durability and have a longer period of usefulness.
A further object of the invention is to incorporate in the impregnating soap or soap compound a porous absorbent, flaky or leafy substance which will materially increase the absorption and retention of a greater quantity of soap or detergent material and mechanically interlock the soap carrying material to the fibers whereby the detergent will be more slowly released during the use of the pad thereby maintaining an improved cleaning action throughout a greatly extended period of usefulness.
A further object of the invention is to provide a fibrous cleaning pad possessing the advantageous structural and mechanical features, the inherent meritorious characteristics and the mode and manner of production herein set forth.
With the above primary and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, as hereinafter described or their equivalents.
In the preferred embodiment of the invention,
the cleaning pad comprises metallic fibers of the steel wool type of commerce of various grades or degrees of fineness according to the conditions of use. Such pad is impregnated with a liquid soap or soap compound in which has been intermixed a quantity of a flaky, leafy porous absorbent material of which corn meal; wood fiour, or fine sawdust have proven quite suitable. These substances are mentioned as exemplary but are not necessarily the only usable materials. Hence the invention is not limited thereto.
The particle size of the intermixed absorbent material is of importance. That found of most satisfactory size is the portion which passes through a No. 40 U. S. Standard mesh screen and remains upon a No. U. S. Standard mesh screen. The screened material is added to a soap solution or compound in quantity approximating ten percent (10%) thereof. A proportion of the comminuted porous absorbent substance materially greater than ten percent of the mixture tends to clog the cleaning pad. Quantities thereof less than five percent of the mixture do not sufficiently increase the retaining capacity of the pad nor the duration of the soap content thereof.
To assure thorough dispersion of the porousmaterial in the soap content and maximum ab,- sorption of soap thereby, these materials are preferably milled together in a percussion type apparatus. For example the soap content and the intermixed porous material may be treated in a conventional paint ball mill, or a hammer mill for a half hour to an hour of treatment. However the same result may be accomplished'by other known methods. Such action not only increases the absorption and intimate combination of the soap or detergent with the intermixed porous substance, but it flattens the particles of the latter into flakes having rough irregular margins which have a tendency to interlock or intertangle with the fibers of the cleaning pad to which they will cling.
Tests have been conducted to determine the increased life of the soap content of the cleaning repeated until the pH agreed with that of the distilled water used.
A liquid soap alone was tested, which permitted only forty strokes over the panel. An addition thereto of suificient 40-60 mesh corn meal to afiord a five percent concentration increased the durability of the soap to eighty strokes. A further addition of the 40-60 mesh corn meal content to a ten percent concentration increased the durability of the soap content to Well over two hundred strokes, at which stage the steel wool pad was worn to apoint where it was no longer usable, while the solution still evidenced a pH of 7.6.
Other tests were conducted with initially solid soaps which were dissolved in water to a five percent concentration and under similar treatment produced results equivalent to those aforementioned. Wood fiour of 40-60 mesh was employed with comparable results. Particles;v of smaller mesh than 40-60 do not cling to the fibers suificiently securely and were not found been made to the use of soap or soap compound as the impregnating material and steel wool as the fibrous pad, it is to be understood'that the invention is not limited thereto, but fibrous pads of other material impregnated with detergents other than soap and soap compounds may be substituted therefor, and comminuted porous absorbent material other than corn meal, wood flour and fine saw dust may be intermixed therewith.
From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement 'of parts without departing from the principle involved or sacri ficing any of its advantages.
While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into efiect, and
the invention is therefore claimed in any of 1 its forms or modifications within the legitimate and valid scope .of'the appended claims.
Having thus described my invention, I claim: 1. The herein described method of retarding too rapid dispersion of soluble permeating detergent material from a fibrous cleaning pad including intermixing a quantity of particles of porous absorbent vegetable material with the soluble detergent material, subjecting the intermixture to percussion treatment whereby at least a portion of the detergent material is bodily incorporated in the porous absorbent particles and causing the detergent charged particles to clingingly engage with the fibers of the cleaning pad.
2. The herein described method of retarding too rapid dispersion of soluble detergent material permeating a fibrous cleaning pad, including intermixing a quantity of particles of porous absorbent vegetable material with the soluble detergent material to the extent of not exceeding ten percent nor not less than five percent of the volume thereof, subjecting the mixture to percussive treatment by which at least a portion of the soluble material is bodily incorporated in the porous absorbent particles and impregnating the fibrous pad with such percussion treated mixture by which the detergent charged particles become entangled with the fibers of the cleaning pad and clingingly resist separation therefrom while,retarding dispersion of the detergent therefrom.
3. A detergent permeated fibrous cleaning pad, including a quantity of flattened particles of porous absorbent vegetable material intermixed with the detergent, the flattened particles being of irregular outline and having serrated margins to become intertangled with the fibers of the cleaning pad, thereby retarding the dispersion of the detergent material from thepad and increasing the durability thereof.
4. The herein described method including intermixing particles of comminuted porous absorbent material with detergent material in a liquid or semi fluid form and subjecting the intermixture to percussion treatment, by which portions of the detergent material are incorporated in the particles of intermixed porous absorbent material and the latter flattened, and thereafter impregnating a fibrous cleaning pad with the detergent intermixture, the flattened particles of which are caused to become entwined with the fibers of the cleansing pad whereby the subsequent physical separation of the detergent material from the pad will be materially retarded.
