Definitions

• This invention relates to carbonated compositions for cleaning textile fibers. More particularly this invention relates to carbonated compositions containing carbonate salt and an acid with a low solubility for delaying the production of carbon dioxide.
• cleaning compositions for cleaning textile fibers such as carpets, upholstery, drapery, and the like.
• Each type of cleaning composition is formulated to loosen and disperse the soil from the textile fibers either physically or by chemical reaction. The soil can then be solubilized or suspended in such a manner that it can be removed from the fibers being cleaned.
• cleaning compositions are based on soaps or detergents, both of which are generically referred to as “surfactants”.
• detergent is meant a synthetic amphipathic molecule having a large non-polar hydrocarbon end that is oil-soluble and a polar end that is water soluble.
• Soap is also an amphipathic molecule made up of an alkali salt, or mixture of salts, of long-chain fatty acids wherein the acid end is polar or hydrophilic and the fatty acid chain is non-polar or hydrophobic.
• Detergents are further classified as non-ionic, anionic, or cationic. Anionic or nonionic detergents are the most common.
• surfactants function because the hydrophobic ends of the molecules coat or adhere to the surface of soils and oils and the water soluble hydrophilic (polar) ends are soluble in water and help to solubilize or disperse the soils and oils in an aqueous environment.
• the various elements of the present invention have been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available cleaning compositions. Accordingly, the present invention provides an improved internally carbonated cleaning solution using an acid with low water solubility.
• the present invention relates to an internally carbonated aqueous cleaning composition for textiles comprising about 20 to 60%, in percent by weight, of at least one carbonate salt, about 20 to 60%, in percent by weight, of at least one acid, the acid having a solubility less than two grams per 100 grams of water at about twenty five degrees Celsius.
• An aqueous medium is added to the carbonate salt and the acid to produce carbon dioxide.
• the composition comprises about 40 to 60% of the acid and about 35 to 50% of the carbonate salt.
• the solid acid is either fumaric acid or adipic acid.
• the carbonate salt is selected from the group consisting of sodium carbonate, sodium percarbonate, sodium bicarbonate, lithium carbonate, lithium percarbonate, lithium bicarbonate, potassium carbonate, potassium percarbonate, potassium bicarbonate, ammonium carbonate, sodium sesquicarbonate, potassium sesquicarbonate, lithium sesquicarbonate, and ammonium sesquicarbonate, and ammonium bicarbonate, or any other effective carbonate salt.
• the aqueous medium is added to the carbonate salt and the acid at a temperature above thirty two degrees Celsius.
• the composition concentration resulting from the carbonate salt and acid in the solution is between about 0.5 to 3%.
• the present invention relates to a method of cleaning textile fibers comprising the steps of applying to the fibers, an internally-carbonating cleaning composition, the composition being prepared by admixing 20 to 60%, in percent by weight, a carbonate salt and 20 to 60%, in percent by weight, an acid with a solubility less than two grams per 100 grams of water at twenty five degrees Celsius, and wherein when the carbonate salt and the acid are mixed in an aqueous medium, the carbonate salt and acid react to produce carbon dioxide.
• Figure 1 illustrates a comparison graph showing the response of carbon dioxide production versus time for fumaric and citric acid
• Figure 2 illustrates a comparison graph showing the response of carbon dioxide production versus time for fumaric and tartaric acid.
• a solid acid and carbonate salt are prepared and admixed in a single container and then diluted with a desired amount of water.
• the carbonate salt may be any one of, or a combination of the group consisting of sodium carbonate, sodium percarbonate, sodium bicarbonate, lithium carbonate, lithium percarbonate, lithium bicarbonate, potassium carbonate, potassium percarbonate, potassium bicarbonate, ammonium carbonate, sodium sesquicarbonate, potassium sesquicarbonate, lithium sesquicarbonate, and ammonium sesquicarbonate, and ammonium bicarbonate, or any other effective carbonate salt.
• the solid acid preferably, has a low solubility, with a maximum solubility of approximately two grams of acid per one Hundred grains of " water at twenty five degrees Celsius.
• solid acids with low solubility examples include Fumaric acid, with a solubility of .63 grams per one hundred grams of water at twenty five degrees Celsius, and Adipic acid, with a solubility of about 1.44 grams per one hundred grams of water at twenty five degrees Celsius. Other solid acids with low solubility will also work.
• the solid acids and carbonate salts are mixed or ground together to form a solid mixture.
• the solid mixture contains from about 20% to 60% carbonate salts and about 20% to 60% of a natural solid acid with a low solubility.
• the most preferable mixture contains 35% to 50% carbonate salt and 40% to 60% acid.
• the water temperature exceeds forty eight degrees Celsius.
• the water temperature may be as low as room temperature.
• the temperature is not below thirty two degrees Celsius as the time for the acid to mix with the water may be excessively long.
• the solution is preferably applied to the textiles as a spray; however, other known methods of applying the solution may be used.
• the pressure is released when the solution is exposed to the atmosphere, and the carbonated cleaning solution breaks into a myriad of tiny effervescent bubbles.
• the combined carbonation action and the cleaning solution results in a low water volume. Specifically, the soils or oil on the fibers being cleaned are surrounded by a complex of carbon dioxide bubbles and polar and non-polar ended molecules that bind with and suspend the soil. The cleaning solution then can be lifted from the fibers into the surrounding carbonating aqueous environment.
• aqueous it is meant that there is a certain amount of water, but that does not suggest that copious amounts of water are present.
• Figure 1 illustrates a comparison graph showing the response time of carbon dioxide production for fumaric and citric acid.
• a sample of carbonate salt solution was prepared at a concentration of 0.01 Molar and at 120 degrees Fahrenheit ( ⁇ 49 degrees Celsius).
• a carbon dioxide ion selective electrode previously calibrated at 120 degrees Fahrenheit, or about 49 degrees Celsius was placed in the solution and initial readings were taken for about one hundred seconds.
• tartaric acid was combined with a sample of carbonate solution at a concentration of 0.01 Molar and at 120 degrees Fahrenheit ( ⁇ 49 degrees Celsius). A maximum level of carbon dioxide production occurred almost immediately and maxed out at approximately 0.0085M. With fumaric acid as the acidulent, the carbon dioxide reached a maximum concentration of 0.0095 M within about 120 seconds of adding the acid. 34 f " Tartaric acicT is a" closer relative to fumaric acid than citric acid. Like fumaric acid, tartaric acid is a diprotic acid with very similar acid strengths for each acidic proton. The main characteristic of these acids is their difference in water solubility. Fumaric acid is about two hundred time less soluble than tartaric acid in water at room temperature.
• fumaric acid is admixed to 190 grams of sodium carbonate, and mixed with five gallons of hot water, around 120 degrees Fahrenheit ( ⁇ 49 degrees Celsius). The amounts of fumaric acid and sodium carbonate may be increased or decreased approximately five to ten grams.
• 252 grams of adipic acid is admixed with 165 grams of sodium carbonate and mixed with five gallons of hot water, around 120 degrees Fahrenheit ( ⁇ 49 degrees Celsius). The amounts of adipic acid and sodium carbonate may be increased or decreased approximately five to ten grams.
• additives commonly found in commercial cleaning compositions may be added without departing from the scope of this invention provided they do not interfere with the interaction of the acids and carbonates and the creation of carbon dioxide.

• These include, but are not limited to, bleaches, optical brighteners, fillers, fragrances, antiseptics, germicides, dyes, stain blockers, preservatives, and similar materials.
