Definitions
- This invention relates to aqueous cleaning compositions and, more particularly, relates to an aqueous cleaning composition having the ability to remove stains, soils, or combinations thereof from textile fibers.
- Carpets containing synthetic polymer fibers are a popular floor covering for both residential and commercial applications. Such carpets are relatively inexpensive and have a combination of desirable qualities, such as durability, comfort, safety, warmth, and quietness.
- polyamide fibers such as nylon 6 and nylon 66
- polyester fibers Two popular synthetic polymer fibers utilized in carpets are polyamide fibers, such as nylon 6 and nylon 66, and polyester fibers.
- the fibers contained in the carpets are severely and permanently stained or soiled when contacted, such as by inadvertent spilling, with certain artificial and natural colorants present in household items, such as tea, coffee beverages made from coffee beans, and soft drink beverages. Many of these colorants are acid dyes colorants, which cause the most severe stains. As a result thereof, carpets are sometimes replaced because of unsightly soiling or staining, even though the carpet has not been worn out.
- stain and staining as used herein with reference to synthetic fibers means discoloration of the fibers caused by a chemical reaction with a chemical substance. Acid dyes are representative of a staining material for nylon fibers.
- soil refers to both organic and inorganic matter which comes in contact with fibers and adhere thereto. Dirt particles, grease, oils, foods, and cosmetics are representative of materials referred to as soils that work their way onto and into various textile fibers.
- fiber as used herein includes fibers of extreme or indefinite length (i.e. filaments) and fibers of short length (i.e. staple).
- fiber as used herein means a continuous strand of fibers.
- the fibers be treated with an additive which coats the fiber and makes the fiber resistant to staining.
- additives are condensation products made from aromatic sulfonic acids, and formaldehyde.
- Colored food beverages such as colored soft drink beverages, tea beverages, and coffee beverages made from coffee beans, present a serious staining problem to textile fibers. Coffee stains are particularly unsightly because of their dark brown color.
- fluorochemicals have been applied to carpet fibers in order to reduce their water and oil wettability.
- the fluorochemical reduces the tendency of soils to adhere to the fibers, thereby making the removal of soils from the carpet fibers easier than if the fluorochemicals were omitted, but offers little protection to the carpet fibers from spills containing acid dye colorants unless the colorants are immediately removed from the fibers.

Abstract
Description
- This invention relates to aqueous cleaning compositions and, more particularly, relates to an aqueous cleaning composition having the ability to remove stains, soils, or combinations thereof from textile fibers.
- Carpets containing synthetic polymer fibers are a popular floor covering for both residential and commercial applications. Such carpets are relatively inexpensive and have a combination of desirable qualities, such as durability, comfort, safety, warmth, and quietness.
- Various types of synthetic polymer fibers are used in making carpets. Two popular synthetic polymer fibers utilized in carpets are polyamide fibers, such as nylon 6 and nylon 66, and polyester fibers.
- The fibers contained in the carpets are severely and permanently stained or soiled when contacted, such as by inadvertent spilling, with certain artificial and natural colorants present in household items, such as tea, coffee beverages made from coffee beans, and soft drink beverages. Many of these colorants are acid dyes colorants, which cause the most severe stains. As a result thereof, carpets are sometimes replaced because of unsightly soiling or staining, even though the carpet has not been worn out.
- The terms "stain and staining" as used herein with reference to synthetic fibers means discoloration of the fibers caused by a chemical reaction with a chemical substance. Acid dyes are representative of a staining material for nylon fibers.
- The terms "soils" as used herein refers to both organic and inorganic matter which comes in contact with fibers and adhere thereto. Dirt particles, grease, oils, foods, and cosmetics are representative of materials referred to as soils that work their way onto and into various textile fibers.
- The term "fiber" as used herein includes fibers of extreme or indefinite length (i.e. filaments) and fibers of short length (i.e. staple). The term "yarn" as used herein means a continuous strand of fibers.
- In an attempt to prevent undesirable staining of fibers and, particularly, fibers contained in carpets, it has been proposed that the fibers be treated with an additive which coats the fiber and makes the fiber resistant to staining. Examples of such additives are condensation products made from aromatic sulfonic acids, and formaldehyde. Although such additives have been somewhat successful in imparting stain resistance, certain problems remain. For instance, many of the additives reduce staining of fibers, but do not totally eliminate it. In addition, traffic on carpet wears off the additives, which leaves the resulting fibers of the carpet with little or no protection against staining.
- Colored food beverages, such as colored soft drink beverages, tea beverages, and coffee beverages made from coffee beans, present a serious staining problem to textile fibers. Coffee stains are particularly unsightly because of their dark brown color.
- Various fluorochemicals have been applied to carpet fibers in order to reduce their water and oil wettability. The fluorochemical reduces the tendency of soils to adhere to the fibers, thereby making the removal of soils from the carpet fibers easier than if the fluorochemicals were omitted, but offers little protection to the carpet fibers from spills containing acid dye colorants unless the colorants are immediately removed from the fibers. In addition, traffic on the carpet wears off the fluorochemicals.
- A number of cleaning solutions have been proposed in the past for removing stains and soils from fibers. For instance, volatile solvent dry-cleaning fluids have been proposed, but such fluids are less than satisfactory in removing water-soluble stains or soils. In addition, aqueous compositions containing synthetic detergents have been proposed for removing stains and soils from fibers, but such compositions have not been found to be particularly effective.
- One of the problems with these cleaning solutions is that while they may, at times, loosen and/or dispense the soil, they fail to pick up or retain the soil, which results in it being redeposited on the fibers. Furthermore, they are not very effective against difficult stains, such as acid and coffee stains. Still further, since acid and coffee stains are not water soluble, aqueous detergent compositions are not particularly effective and many times it is difficult to remove all of the detergent from the fiber surface, even when rinsed with large amounts of water or steam. As a result thereof, the carpet fibers become tacky due to a film of detergent. The film attracts and retains soils, which results in a cleaned carpet that will soil more easily after a cleaning than prior thereto.
- Finally, many of the aqueous cleaning compositions require large amounts of water. This causes the fibers in the carpet and, many times, the pad under the carpet, to become saturated with water, which can result in degradation of the pad and/or carpet.
- A method of treating cloths with an aqueous mixture of hydrogen peroxide and ethanol is known from GB-A-2.072.643. A method of treating carpets with an aqueous mixture of hydrogen peroxide and isopropanol is known from US-A-3.607.760.
- The present invention provides a cleaning composition suitable for removing stains and soils from synthetic polymer fibers which overcomes, or at least mitigates, many of the above-described problems.

- Another object of the present invention is the use of an aqueous cleaning composition having a pH in the range of from about 9 to about 12 and comprising an effective amount of water-soluble alcohol containing 1 to about 5 carbon atoms; an oxidizing agent present in an amount in the range of from about 3 to about 15 percent by weight of said aqueous cleaning composition and comprising a peroxyhydrate; a pH adjustment substance; and the balance water for spot cleaning stained or soiled portions of a synthetic polymer fiber carpet.
- The composition is very effective in removing stains from coffee beverages, even when the beverages have remained on the fiber for extended periods of time, e.g., 30 minutes or more. Finally, the use of the composition does not result in appreciably degrading the fibers.
- Alcohols which are suitable for use in the invention include water-soluble alcohols containing up to 5 carbon atoms, such as methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, n-butyl alcohol, isobutyl alcohol, sec-butyl alcohol, tert-butyl alcohol, tert-pentyl alcohol.

- The amount of oxidizing agent and alcohol utilized in the aqueous cleaning composition will vary over a wide range.
- For fibers having stains from coffee beverages, the amount of oxidizing agent employed is generally an amount in the range of from about 3 to about 15 percent by weight of aqueous composition and, preferably, an amount of from about 3 to 12.5 percent by weight of aqueous composition. The amount of alcohol will generally be an amount in the range of from about 10 to about 30 percent by weight of aqueous composition and, preferably, an amount of from about 10 to about 20 weight percent based on the weight of the aqueous composition.

In any case, the observable effect is that the utilization of the aqueous solution containing the peroxyhydrate and alcohol very effectively removes, or at least substantially reduces, soils and stains, particularly coffee stains, in the fibers.

- The invention is further exemplified by the examples below, which are presented to illustrate certain specific embodiments of the invention, but are not intended to be construed so as to be restrictive of the spirit and scope thereof.
- An amount of 10 milliliters of a beverage comprising black coffee which had a temperature of 180°F was poured into the center of each piece of a 6 inch by 6 inch sample of a commercial carpet. The samples comprised nylon, polyester, or polypropylene. The samples were then allowed to air dry at ambient temperatures for a period of 48 hours. After 48 hours, each stain was sprayed with a commercial carpet detergent. The detergent was allowed to contact the sample for a period of one minute after being lightly agitated by means of a finger. Thereafter, the detergent was removed from the sample using a commercial hot water extraction machine having a 4 inch wand attached to a vacuum hose. Next, the stain was sprayed with 100% white vinegar, which was allowed to stand for one minute and subsequently removed from the carpet in the same manner as the detergent. The coffee stains were not appreciably removed from the samples after these treatments.
- Thereafter, each coffee stain was sprayed with an aqueous cleaning composition comprising 10 percent by weight isopropyl alcohol, 30 percent by weight of an aqueous hydrogen peroxide composition containing 30 percent by weight hydrogen peroxide (9 percent by weight hydrogen peroxide), 10% by weight of an ammonium hydroxide for pH adjustment, and 50 percent by weight of water.

Upon visual observation, all traces of the coffee stain were removed from each sample.
- Although certain preferred embodiments of the invention have been herein described for illustrative purposes, it will be appreciated that various modifications and innovations of the procedures recited may be effected without departure from the basic principles which underlie the invention as defined in the claims.
