Abstract
Solvent treatment methods for treating fabric articles, more particularly it relates to glycerine derivative solvent treatment methods are provided by the present invention.
Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 60/483,347, filed on Jun. 27, 2003; and U.S. Provisional Application Ser. No. 60/520,517, filed on Nov. 17, 2003.
- The present invention relates to solvent treatment methods for treating fabric articles, more particularly it relates to glycerine derivative solvent treatment methods.
- Typically, the laundering of fabric articles is performed by conventional aqueous immersive laundry cleaning or dry cleaning.
- Conventional laundry cleaning is carried out with relatively large amounts of water. Cleaning additives such as surfactants, enzymes, bleaches, and fabric softeners are added and mixed with the water to provide cleaning, whitening, softening and like benefits. The aqueous-based laundering process is typically performed in a washing machine or by hand at the consumer's home, or in a dedicated place such as a coin laundry. Although washing machines and laundry detergents have become quite sophisticated, the conventional aqueous-based laundry process still exposes the fabric articles to risks of shrinkage, wrinkles, and other undesirable results.
- Most dry cleaning processes rely on non-aqueous solvents for cleaning. By avoiding water these processes minimize the risk of shrinkage and wrinkling for certain fabrics, including cotton, polyester, silk, rayon, wool and various blends of these materials. The need for handling and recovering large amounts of solvents make these dry cleaning processes unsuitable for use in the consumer's home. The need for dedicated dry cleaning operations makes this form of cleaning inconvenient and expensive for the consumer.
- Moreover, the conventional solvents for the dry cleaning process, such as perchloroethylene (“PERC”), are causing environmental and health concerns.
- Accordingly, there is a need provide an alternative solvent for laundering fabric articles that is safe, environmentally-friendly, and with the undesirable effects of shrinkage, wrinkles, and the like. Moreover, there is a need for an alternative solvent that provide all of the above benefits and is suitable for use in home laundering as well in commercial laundering services.
- The present invention relates to an improved solvent treatment method for treating a fabric article which comprises the step of contacting the fabric article with a glycerine derivative solvent, optionally an adjunct solvent, an adjunct ingredient, a polar phase and mixtures thereof.

For example, one suitable silicone solvent is SF-1528 available from GE Silicones.
- Additional examples of other environmentally-friendly solvents include lipophilic fluids that have an ozone formation potential of from about 0 to about 0.31, lipophilic fluids that have a vapor pressure of from about 0 to about 0.1 mm Hg, and/or lipophilic fluids that have a vapor pressure of greater than 0.1 mm Hg, but have an ozone formation potential of from about 0 to about 0.31. Non-limiting examples of such lipophilic fluids that have not previously been described above include carbonate solvents (i.e., methyl carbonates, ethyl carbonates, ethylene carbonates, propylene carbonates, glycerine carbonates), succinate solvents (i.e., dimethyl succinates), and mixtures thereof.
- A methodology to determine ozone reactivity is discussed in W. P. L. Carter, “Development of Ozone Reactivity Scales of Volatile Organic Compounds”, Journal of the Air & Waste Management Association, Vol. 44, Page 881-899, 1994. “Ozone Reactivity” as used herein is a measure of the ability of a volatile organic compound (VOC) to form ozone in the atmosphere. It is measured as grams of ozone formed per gram of volatile organics. “Vapor Pressure” as used can be measured by techniques defined in Method 310 of the California Air Resources Board.
- In one embodiment, the lipophilic fluid comprises more than 50% by weight of the lipophilic fluid of cyclopentasiloxanes, (“D5”) and/or linear analogs having approximately similar volatility, and optionally, the D5-containing lipophilic fluid is complemented by other silicone solvents.
- Adjunct Ingredients
- Optionally, adjunct ingredients may be added to the glycerine derivative solvents.
- Suitable cleaning adjuncts include, but are not limited to, builders, surfactants, enzymes, bleach activators, bleach catalysts, bleach boosters, bleaches, alkalinity sources, antibacterial agents, colorants, perfumes, pro-perfumes, finishing aids, lime soap dispersants, composition malodor control agents, odor neutralizers, polymeric dye transfer inhibiting agents, crystal growth inhibitors, photobleaches, heavy metal ion sequestrants, anti-tarnishing agents, anti-microbial agents, anti-oxidants, anti-redeposition agents, soil release polymers, electrolytes, pH modifiers, thickeners, abrasives, divalent or trivalent ions, metal ion salts, enzyme stabilizers, corrosion inhibitors, diamines or polyamines and/or their alkoxylates, suds stabilizing polymers, solvents, process aids, fabric softening agents, optical brighteners, hydrotropes, suds or foam suppressors, suds or foam boosters, fabric softeners, antistatic agents, dye fixatives, dye abrasion inhibitors, anti-crocking agents, wrinkle reduction agents, wrinkle resistance agents, soil release polymers, soil repellency agents, sunscreen agents, anti-fade agents, anti-static agents, and mixtures thereof. In any event, any adjunct ingredient must be suitable for use in combination with the solvent.
- Suitable adjunct ingredients may include detersive enzymes, such as proteases, amylases, cellulases, lipases and the like, as well as bleach catalysts including the macrocyclic types having manganese or similar transition metals all useful in laundry and cleaning products can be used herein at very low, or less commonly, higher levels. For example, the detersive enzymes and/or bleach catalyst may be present in the composition of the present invention at a level typically less than about 5%, more typically less than about 1%, and even more typically less than about 0.1%, by weight of the composition.
- Adjunct materials that are catalytic, for example enzymes, can be used in “forward” or “reverse” modes. For example, a lipolase or other hydrolase may be used, optionally in the presence of alcohols as adjuncts, to convert fatty acids to esters, thereby increasing their solubility in the solvent. This is a “reverse” operation. In contrast, the normal use of this hydrolase in water is to convert a less water-soluble fatty ester to a more water-soluble material.
- The adjunct ingredient suitable for use herein may also comprise emulsifiers. Emulsifiers are well known in the chemical art. Essentially, an emulsifier acts to bring two or more insoluble or semi-soluble phases together to create a stable or semi-stable emulsion. It is preferred in the claimed invention that the emulsifier serves a dual purpose wherein it is capable of acting not only as an emulsifier but also as a treatment performance booster. For example, the emulsifier may also act as a surfactant to boost the cleaning performance.

If the polar phase includes water, water preferably comprises at least about 0.1%, preferably at least about 0.5% water by weight of the fabric article and at most about 10%, preferably at most about 5% water by weight of the fabric article. In an alternative embodiment, water comprises from about 0.01 vol % to about 5 vol %, preferably from about 0.1 vol % to about 3 vol %, more preferably from about 0.25 vol % to about 1 vol % of the solvent mixture contacting the fabric article.
- During the contacting step, the weight ratio of composition applied to the fabric article to the dry weight of the fabric article may range from 0.5:1 to 30:1, preferably from about 0.8:1 to about 5:1, more preferably from about 1:1 to about 1.5:1. In other words, the method may be non-immersive as well as immersive. The fabric article may be mechanically agitated, tumbled or otherwise moved in a treatment chamber to achieve uniform application of the composition to the fabric articles being treated.
- The composition of the present invention can be prepared by mixing the ingredients by any known process chosen by the formulator. The mixing may even be performed by the user by shaking or other known mixing methods.
- The adjunct solvent may comprise a lipophilic fluid, including but not limited to a linear siloxane, a cyclic siloxane, or mixtures thereof. In some embodiments, the adjunct solvent may comprise one or more cyclic siloxane solvents, such as decamethylcyclopentasiloxane. Due to the flash points of the aforementioned siloxanes, if the siloxanes are included as the adjunct solvents, the method is typically carried out at less than about 80° C.
- While carrying out the method of the present invention, the fabric articles may also be exposed to a surfactant and/or other adjunct ingredients, either separately or as a result of being contained within the glycerine ether solvent, polar phase and/or the adjunct solvent.
- Cleaning System and Apparatus
- A cleaning system and apparatus suitable for use in the method of the present invention are described below. The cleaning system comprises a fabric article treating vessel, a dry cleaning solvent reservoir, and optionally, a sensor for monitoring the contaminant level in the dry cleaning solvent. When contaminants concentration exceeds some pre-determined value, it would indicate that the dry cleaning solvent has reached maximum contaminant holding tolerance and needs to be purified. Additionally, solvent purification/recovery device comprising a chemical modification unit capable of conducting the purification method of the present invention may also be provided as an integral part of the system/apparatus. However, it needs not be. The solvent purification/recovery unit can be a stand-alone device, separate from the dry cleaning system.
- Any suitable fabric article treating vessel known to those of ordinary skill in the art can be used. The fabric article treating vessel receives and retains a fabric article to be treated during the operation of the cleaning system. In other words, the fabric article treating vessel retains the fabric article while the fabric article is being contacted by the dry cleaning solvent. Nonlimiting examples of suitable fabric article treating vessels include commercial cleaning machines, domestic, in-home, washing machines, and clothes drying machines.
- The methods and systems of the present invention may be used in a service, such as a cleaning service, diaper service, uniform cleaning service, or commercial business, such as a Laundromat, dry cleaner, linen service which is part of a hotel, restaurant, convention center, airport, cruise ship, port facility, casino, or may be used in the home.
- The methods of the present invention may be performed in an apparatus that is a modified existing apparatus and is retrofitted in such a manner as to conduct the method of the present invention in addition to related methods.
- The methods of the present invention may also be performed in an apparatus that is specifically built for conducting the present invention and related methods.
- Further, the methods of the present invention may be added to another apparatus as part of a dry cleaning solvent processing system. This would include all the associated plumbing, such as connection to a chemical and water supply, and sewerage for waste wash fluids.
- The methods of the present invention may also be performed in an apparatus capable of “dual mode” functions. A “dual mode” apparatus is one capable of both washing and drying fabrics within the same vessel (i.e., drum). These apparatuses are commercially available, particularly in Europe. Additionally, the method of the present invention may also be performed in an apparatus capable of performing “bi-modal” cleaning functions. A “bi-modal” apparatus is one capable of performing both non-aqueous washing and aqueous washing in the same vessel, wherein the two washing modes can be performed in sequential washing cycles or in a combination washing cycle. Additionally, the bi-modal machine is capable of fully drying the clothes without having to transfer them to a separate machine. That is, a machine can have the bi-modal function as well as the dual-mode function.
- An apparatus suitable for use in the present invention will typically contain some type of control systems, including electrical systems, such as “smart control systems”, as well as more traditional electromechanical systems. The control systems would enable the user to select the size of the fabric load to be cleaned, the type of soiling, the extent of the soiling, the time for the cleaning cycle. Alternatively, the control systems provide for pre-set cleaning and/or refreshing cycles, or for controlling the length of the cycle, based on any number of ascertainable parameters the user programmed into the apparatus. For example, when the collection rate of dry cleaning solvent reaches a steady rate, the apparatus could turn its self off after a fixed period of time, or initiate another cycle for the dry cleaning solvent.
- In the case of electrical control systems, one option is to make the control device a so-called “smart device”, which provides smart functions, such as self diagnostics; load type and cycle selection; Internet links, which allow the user to start the apparatus remotely, inform the user when the apparatus has cleaned a fabric article, or allow the supplier to remotely diagnose problems if the apparatus malfunctioned. Furthermore, if the system of the present invention is only a part of a cleaning system, the so called “smart system” could be communicating with the other cleaning devices which would be used to complete the remainder of the cleaning, such as a washing machine, and a dryer.
- All documents cited in the Detailed Description of the Invention are, in relevant part, incorporated herein by reference; the citation of any document is not to be construed as an admission that it is prior art with respect to the present invention.
- While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
