Abstract
Abstract of the Disclosure A deodorizing latex sheet material, insoles for use in reducing foot odor, and methods of making these products. Shoe inserts are produced comprising a sole-shaped sheet or the like of foamed latex impregnated with activated charcoal. When such a shaped sheet is used as a shoe insert or insole it is found to substantially reduce or even eliminate foot odors frequently associated with perspiring feet.
Description
Background of the Invention Activated charcoal has long been used as a filter aid with both liquids and gases for the purpose of clarifying liquids and deodorizing liquids and gases.
In recent times it has been proposed as for example in British Specification No. 1,270,809 to incorporate activated charcoal into a fibre web or mat, the web or mat being supported by a backing material such as cloth obtained from natural sources such as cotton, or formed of a synthetic such as nylon, and shaped so that the resulting web fits into and covers the inner sole of a shoe. It has also been proposed to attach a layer or coating of a foam material such as polyurethane foam to such a web for the purpose of providing increased strength and springiness.
Summ ry of the Invention My invention is directed to an odor absorbent comprising in sheet form, open-celled foam having dispersed therethrough finely divided activated charcoal. The odor absorbent of my invention may be such that at least one surface of said sheet has secured thereto a second sheet at least the outer surface of which is free of finely divided activated charcoal.
The said open-celled foam may be selected from the group consisting of latex foams, polyurethane foams and vinyl chloride plastisol foams. A preferred foam is one formed of latex. Moreover, the said second sheet may be a textile.
My invention is also directed to a shoe insert comprising a sheet of open-celled foam having dispersed therethrough finely divided activated charcoal. This unique shoe insert, or insole, effectively and economically minimizes odors which are often associated with feet and which occur in conjunction with or as a result of perspiration. In general, my shoe ~<~

- lO~f~Q43 insert comprises a foamed material, conveniently in the form of a sheet which has been cut or otherwise shaped to conform to the basic outline of a foot, and is adapted for insertion int:o a shoe. The shoe insert is formed-by incorporating acl:ivated charcoal into a chemical mix used to produce an open-celled foam through whose interstitial spaces air can pass.
After incorporation of the charcoal into a latex-containing chemical mix, the material is homogenized and spread uniformly into a web of cloth or the like, and then passed under a doctor blade to produce a desired thickness.
The resulting product is then heat processed in order to produce a latex foam which is bonded to the web.
The resulting latex-foam sheets, containing charcoal dispersed therethrough, are then cut into such sizes as are appropriate for fitting comfortably into shoes, male or female.
In use the insole is inserted into the shoe with the impregnated latex facing downward in the shoe to thereby permit contact of the web or backing material with the foot, and with the sock covering it.
The especially excellent effective~ess of my shoe insert seems to result from the circulation of air and vapors through and around the highly absorbent carbon particles, which occurs when the shoe containing such insert is worn.

Description of the Preferred Embodiment So that my invention may be fully understood, I shall hereinafter describe a specific example illustrating the practice of my invention. This illustration is for that purpose only, and is not intended to either limit the scope of the invention or of the claims appended hereto.
EXAMPLE I
Ingredients Dry Weight GR-S Latex 100.0 lbs.
Sulfur 1.5 lbs.
Zinc Oxide4.0 - 5.0 lbs.
Surfactant 9.0 lbs.
Filler 100.0 lbs.
Activated Charcoal25.0 - 32.0 lbs.
Antioxidant 1.2 lbs.
Accelerator 2.5 lbs.
Where "weight percent" is taken as the amount of a given component over the total material dry weight, multiplied by 100, the above compositions range from greater B
~046043 than about 10 (10.2) wei~ht percent to about 13 (12.8) weight percent activated charcoal.
The GR-S latex, a synthetic cold type styrene-butadiene manufactured by the Goodyear Company of Akron, Ohio, is used in the form of an aqueous slurry (143.0 lbs.). And the activated charcoal, available under the trade nameNu-Char, is also used in the form of an aqueous slurry (150.0 lbs.).
The procedure used is as follows: The latex slurry is weighed out into a suitable mixing vessel and there is then added 9.0 lbs. of the surfactant, dioctyl-sodium-sulfo-succinate, available from the American Cyanamid Company of New York, under the trade name of Aerosol O T. There is then added 2.5 lbs. of a suitable accelerator, followed by additions of 1.5 lbs. of rubber makers grade sulfur, 4.0 to 5.0 lbs. of zinc oxide (American Process) and 1.2 lbs. of trioctyl phosphite antioxidant.
Silica flour filler (100.0 lbs.) is then added, followed by addition of the activated charcoal aqueous slurry (25-32 lbs. of which is Nu-Char).
If it is desired to increase the viscosity of the foregoing mix, a suitable thickener e.g. *Methocel may be added.
The above components are then mixed to form a homo-genous mass, which is then fed into a hopper, thence into a homogenizer, preferably an *Oakes mixer, which is a rotor stator type homogenizer. Preferably two mixers are used in series. At the first mixer (called a pre-frother) air is injected to control the pour density of the product. The base weight of the finished product is controlled by regulation of this air.
The material is then pumped into the second mixer -also a homogenizer - where the froth is refined controlling the cell structure size.
*Trade Mark -4-11~)46~43 After the mix leaves the second mixer and onto a flat surface (belt or table) covered with a layer of fabric which serves as a backing for the finished insert the thick-ne~ss of the flow is controlled by a doctor blade set to give a finished foam gauge of 80/1000 inch.
Instead of applying the mix onto a flat surface covered with a layer of fabric, as described above, the latex mix may be applied to a transfer paper instead. In other words, my sheet material can be produced with or without a fabric laminate.
Cup weights are taken after the mix leaves the second mixer; cup weights between 85 and 90 grams are acceptable, 87 grams being preferred. The tare weight (cup) is 24 grams.
The resulting material is then cured and dried in a forced hot air oven at temperatures ranging from 310F to 350F, with approximately 3 minutes of dwell time.
It will be understood, of course, by those skilled in the art that variations in the exact amounts and precise kinds of ingredients used in producing my charcoal-loaded latex foam are possible. Thus the levels of finely ground activated charcoal used may be varied rather widely, for example 35% or higher, by weight of the chemical mix producing the latex foam (dry basis) may be used, limited of course by the difficulty of incorporation into the latex mix, economic considerations, appearance and the like.
And though one specific latex foam formulation has been set forth in the foregoing example, those persons skilled in the art will understand that other foam formulations may be used, preferably those which can be processed to form an open-J!j~" - 5-104~43 celled foam which breathes and allows for the passage of air through its interstitial spaces.
While it is presently preferred that the open-celled foam in sheet form comprising my invention be produced using latex, it is also contemplated, and is within the broad concept of my invention, that other open-celled foams may be used, such as polyurethane foams and vinyl chloride plastisol foams, expecially where a slightly more firm product is desired.
