Description

METHOD WITH A DUCI R U N BUSINESS OF LAVAN DERÍA WITH CARBON DIOXIDE Related requests This request refers to a codependent patent application, case of lawyer no. C6577 (V) entitled "Method for conducting a laundry business for cleaning fabrics at low glass transition temperature", the description of which is incorporated herein by reference and filed concurrently therewith.

Field of the invention This invention is directed to a method for conducting a laundry business. More particularly, the invention is directed to a method for cleaning genres, where dirty laundry fabrics are collected, cleaned and delivered to the consumers who request the service.

BACKGROUND OF THE INVENTION Many commercial dry cleaning establishments exist around the world today. Such establishments require the consumer to deliver their laundry to the dry cleaning establishment and pick up their clothing at a later time after the laundry has been cleaned. Other cleaning businesses clean ordinary laundry (for example, clean laundry with detergent and water). equal to dry cleaning establishments, these cleaning businesses also require the consumer to deliver their laundry in the cleaning business and pick up the laundry at a later time after the laundry has been washed. Unfortunately, conventional cleaning facilities do not fully respond to the needs of families subjected to demands in the new millennium. This is true because most cleaning facilities require the customer to deliver and pick up their own clothes. In addition, most cleaning facilities are not used to clean both ordinary laundry and laundry that requires dry cleaning. Moreover, conventional dry cleaning facilities are becoming less desirable because they usually clean clothes with environmentally unfriendly solvents such as perchlorethylene. Accordingly, this invention is directed to a method for conducting a laundry business. The laundry business contains the ability to collect, clean and deliver laundry to customers who require the service. The laundry business provides environmentally friendly dry cleaning alternatives, is competitive in cost and does not cause "damage to dirty laundry genres focused on cleaning.

Support material Efforts have been described for dry cleaning with environmentally friendly solvents. In the US patent no. 5,676,705, describes a dry cleaning method which employs dioxide densified carbon. Other efforts have been described for dry cleaning with carbon dioxide. In the US patent no. No. 5,683,473, dry cleaning with carbon dioxide and a surfactant is described. Still further, the U.S. patent no. 5,683, 977 describes a superior dry cleaning system with carbon dioxide and a surfactant auxiliary.

BRIEF DESCRIPTION OF THE INVENTION In a first aspect, this invention is directed to a method for conducting a laundry business comprising the steps of: (a) collecting dirty laundry gender from a customer in a residential home or a customer in a business and transporting the collected dirty laundry sort to a cleaning facility of the laundry business, or (b) gathering dirty laundry goods from a central laundry delivery location, the central laundry delivery location being within the facility cleaning the laundry business or at a location which is at a driving distance from the laundry business cleaning facility, (c) or both; (d) clean the dirty laundry genre to produce clean laundry gender; and (e) deliver the clean laundry gender to the customer or allow the customer to pick up the clean laundry gender at a location of collection, with the condition that the laundry business be of the type for which a first portion of dirty laundry gender is cleaned with a dry cleaning technique using a densified gas and a second portion of the dirty laundry sort is cleaned with a dry cleaning technique that does not comprise carbon dioxide, wherein the first dirty laundry gender portion does not comprise a portion having a mixture with more than about 40.0% acetate or a portion having about 100% acetate or both In a second aspect, this invention is directed to a laundry business that separates clothing comprising a portion with more than about 40.0% acetate fabric that does not comprise a portion with more than 40.0% acetate, wherein the fabric with more than approximately 40.0% acetate is not cleaned with a solvent which comprises a carbon dioxide. In a third aspect, this invention is directed to the laundry business as described in the first and second aspects of this invention, which further comprises the step of separating a third portion of dirty laundry fabric to be cleaned with water and detergent (by example, ordinary laundry). In a fourth aspect, this invention is directed to a laundry business in a building to perform at least a portion of the laundry business disclosed in the first three aspects of this invention.

Detailed description of preferred modalities As noted above, it has become increasingly difficult in the new millennium for family members to handle basic household chores. Moreover, consumers are very concerned about the environment and in particular they prefer that no harmful chemicals be used to, for example, dry-clean their clothes. Attempts have been made to dry clean clothes with environmentally friendly solvents. However, certain amiable solvents, such as densified gases such as densified carbon dioxide, have been shown to cause shrinkage of the fabric when the dirty laundry fabric being cleaned in carbon dioxide, comprises a portion with more than about 40.0%. of acetate. The higher business method described in this invention is designed to make household chores much less burdensome for the consumer, while at the same time cleaning the goods in a manner that is safe for the environment as well as for the goods being cleaned. . The dirty laundry fabric, which is accumulated via this invention, is limited only to the extent that the fabric can be cleaned in a commercial cleaning facility or in a household machine. Such dirty laundry includes men's and women's suits, coats, mats, pants, curtains, upholstery and shirts. The sort of dirty laundry can be collected from the consumer in his home, place of work or both. The collection of the dirty laundry sort is achieved by the laundry business of this invention via delivery personnel who use delivery vehicles. such as vans. The dirty laundry sort that is collected by the delivery personnel is delivered to a cleaning facility of the laundry business of this invention (usually in, for example, t laundry bags). Dirty laundry items can also be collected at a central laundry delivery location. The central laundry delivery location can be directly inside the laundry business cleaning facility or at a location which is at a driving distance from the cleaning facility. If, for example, the consumer delivers dirty laundry goods to a central laundry delivery location not located within the laundry business cleaning facility, delivery personnel will pick up and deliver such dirty laundry goods to a laundry facility. of the laundry business. As used in this, the central laundry delivery location is defined by including a box or drawer (eg, container or drawer) capable of maintaining dirty laundry goods as well as a real laundry shop with or without laundry cleaning machines. The cleaning facility, as used herein, is defined to include a real laundry store with laundry cleaning machines or an installation with laundry cleaning machines and no actual laundry store. The collection application, as used herein, is defined as including any box, drawer, office or store front where the consumer can pick up their clean goods. By driving distance is meant less than approximately 250 kilometers. Laundry, as used in the present, is defined as the cleaning of soils via runoff or non-aqueous solvent. , With respect to the dirty laundry sort accumulated by the laundry business of this invention (for example, the dirty laundry sort collected by the laundry business and assembled at the delivery locations), such accumulated dirty laundry goods can be monitored. by any means of inventory control known in the art. Such means of inventory control and - i * include stamping dirty laundry goods with a heat brand, using conventional bar codes, using conventional paper labels and receipts, labeling laundry bags (for example, especially when the consumer use a laundry delivery location) or use conventional radio frequency inventory chips, such as those made commercially available by SCS Corporation. Subsequent to the accumulation of soiled laundry goods, soiled laundry goods comprising a portion with a mixture with more than about 40.0% acetate or a portion having about 1 00% acetate, or both, are separated from the genera. laundry products that do not comprise a portion with a mixture with more than about 40.0% acetate or a portion having about 1 00% acetate. This separation is achieved by, for example, a laundry technician who reads the labels in dirty laundry goods. In addition, if the accumulated dirty laundry goods do not require dry cleaning, such goods are separated by, for example, the laundry technician himself. From Optionally, the laundry technician may use an analytical device, such as an infrared spectrophotometer or an ultra violet / visible spectrophotometer to help identify the genders. Accordingly, three portions of dirty laundry goods can accumulate by the laundry business of this invention. The first portion of soiled laundry goods and the second portion (most requiring dry cleaning) of soiled laundry goods are, again, soiled laundry goods without a portion with a mixture with more than about 0.5% acetate or a portion having about 100% acetate and laundry soils comprising a portion with a mixture having more than about 40.0% acetate or a portion having about 100% acetate, or both, respectively. The third portion of dirty laundry goods are. genres that do not require dry cleaning. All percentages are used in this invention are by weight. Accordingly, by way of illustration, a ladies suit jacket comprising a liner (portion), which is approximately 100% by weight acetate or a neck (portion), which is a mixture comprising more than about 40.0% by weight of acetate, or both, would not be dry cleaned via this invention with carbon dioxide. In this invention, the first portion of the dirty laundry fabric does not comprise more than about 40.0% acetate as described above (and requires dry cleaning) is preferably cleaned with a densified gas, such as densified carbon dioxide ( may other densified gases are used and include propane as described in US Pat. Nos. 5, 1 58,704 and 5,266, 205, the descriptions of which are incorporated herein by reference). Such a densified gas is a gas at a standard temperature and pressure and is the preferred solvent employed in this invention to clean a dirty laundry cloth which, again, does not comprise more than 40.0% acetate as described above. Moreover, the densified gas can be, within the dry cleaning process, a gas, liquid or supercritical fluid depending on how densified the gas is (how much pressure is applied at a given temperature) in the laundry system (for example)., apparatus) of the cleaning facility used in the laundry business of the invention. When carbon dioxide is used to clean the dirty laundry fabric that does not comprise a portion with a mixture with more than about 40.0% acetate or a portion having -t about 1 00% acetate, or both, surfactant is usually used. . Such a surfactant may be an end-functionalized polysiloxane similar to those represented in general, by the formula Bt-A-B2. wherein B1 and B2 are each independently an end-functional group and A is a polysiloxane, such as poly idimethylsiloxane (having a weight average molecular weight of from about 75 to about 400,000). The end-functionalized polysiloxanes are usually represented by the formula: wherein n is an integer from about 1 to about 10,000, preferably from about 1 to about 1 00. At least one, and preferably both, of Bt and B2 are solvent groups, such as lipophilic or hydrophobic groups (eg. example, anionic, cationic), but they are not CO2-phylic groups. Each R is independently an alkyl, aryl or haloalkyl, with perfluoroalkyl, C 1 -C 4 alkyls, phenyl and trifluoropropyl being the preferred R groups. With respect to Bi and B2, such end-functional groups can be derived from silicones with reactive groups that produce end-functional materials on contact with a substrate. Illustrative examples of such reactive groups include vinyl, hydride, silanol, alkoxy / polymeric alkoxide, amine, epoxy, carbinol, methacrylate / acrylate, mercapto, acetoxy / chloro / dimethylamine portions. A more detailed description of the s of end-functionalized polysiloxanes which can be used in the laundry business of this invention can be found in WO 99/10587, the disclosure of which is incorporated herein by reference. Other surfactants that can be used in carbon dioxide, when cleaning dirty soils that do not include acetate (as described above), include those generally classified as diols or acetylenic alcohols as represented by the I I Forms below, respectively: R * C ~ H (albohol) 2 / RO wherein R *, R1, R3 and R4 are each independently hydrogen atoms or linear or branched alkyl groups comprised by 1 to 38 carbons and R2 and R5 are each hydrogen atom or hydroxyl-terminated polyalkylene oxide chains derived from 1 to 30 units of alkylene oxide monomer of the following structure: wherein Re, R7, R8 and R9 are each independently hydrogen atoms, linear or branched alkyl groups having about 1 to about 5 carbons or fenílo. The most preferred surfactants that can be used in this invention when carbon dioxide is used to clean soiled laundry fabrics, which do not comprise a mixture with more than 0.5% acetate or a portion with approximately 100% acetate, include those that have the formula: M Dx D * wherein M is a terminal group of trialkylsiloxy lo, Dx is a skeleton d dialkylsiloxy, which is solvent-phylic and D * and is one or more alkylsiloxy group, which are substituted with a solvent-phobic group, where each group solvent-phobic is independently defined by the formula: (CH2) a (C6H4) b (A) d - [(L)? - (A ') r] "- (L') gZ (G) h where a is 1 -30, b is 0 or 1, C6H is unsubstituted or ^ substituted with an alkyl or alkenyl of d_? o, and A and A 'are each independently a linker moiety representing an ester, a keto , an ether, a thio, an amido, an amino, a fluoroalkyl of C, .4, a fluoroalkenyl of C1.4, a polyalkylene oxide of straight or branched chain, a phosphate, a sulfonyl, a sulfate, an ammonium and Mixtures of the same, L and L 'are each independently a straight or branched chain alkyl or alkenyl of C ^ or an aplo. which is unsubstituted or substituted, E is 0-3, F is 0 or 1, N is 0-1 0, G is 0-3, 0 is 0-5, is it a hydrogen, a carboxylic acid, a hydroxy, a phosphate, a phosphate ester, a sulfonyl, a sulfonate, a sulfate, a straight or branched chain polyalkylene oxide? , a nitrile, a glyceryl, an aryl unsubstituted or substituted with an alkyl or alkenyl of C? -30 l a carbohydrate unsubstituted or substituted with an alkyl or alkylene of C- |.10 or an ammonium, G is an anion or cation, such as H +, Na +, Li +, K +, NH 4 \ Ca + 2, Mg + 2, Cl ", Br", I ", mesylate or tosylate, and h is 0-3.Such surfactants are described in U.S. Patent Nos. 5,676, 705, 5, 683, 977, 5, 683, 473, commonly ceded to Lever Brothers Company, a Conopeo Division, I nc. , the descriptions of which are incorporated herein by reference. When performing actual cleaning of soiled laundry goods that do not comprise a portion with a blend with more than about 40.0% acetate or a portion with about 100% acetate, the cleaning process takes place with the preferred densified gas which is carbon dioxide, which is maintained at a temperature of from about 0.0 to about 100 ° C, and preferably from about 5.0 to about 40.0 ° C, and most preferably from approximately 8.0 ° C to approximately 30 ° C, including all the ranges subsumed therein. More so, when the densified gas (for example, dioxide carbon) is used, it is usually maintained at a pressure from about 1.033 to about 703 kg / cm2, and preferably from about 1.575 to about 281.2 kg / cm2, and most preferably from about 45.695 to about 63.27 kg / cm2, including all the ranges subsumed therein. When a densified gas, such as carbon dioxide, is used to clean the soiled laundry goods of this invention that do not comprise a portion with a mixture with more than about 40.0% acetate or a portion with about 100% acetate, The machine that is used for cleaning is well known in the art. Such a machine normally comprises a gas supply, an impurity tank and a condenser. The machine may further comprise a means for agitation; in particular, when the contaminated substrate focused for removal is a genus. The means for agitation can be, for example, a mechanical device similar to a mechanical drum, or a gas jet agitator. Machines recognized in the art that can be used in this invention (for example, when carbon dioxide is used) can be found in US Pat. 5,943,721, 5, 925, 192, 5, 904, 737, 5,412,958, 5, 267,455 and 4, 01 2, 1 94, the descriptions of which are hereby incorporated by reference. When carbon dioxide is used, the amount of surfactant used is from about 0.01% to about 1.0%, and preferably, from about 0.02% to about 2.0% by weight of surfactant based on total weight of the surfactant and carbon dioxide, including all ranges subsumed therein. In a most preferred embodiment, a polar solvent, such as water, is employed together with the surfactant in the cleaning system comprising carbon dioxide. The amount of polar solvent used is usually from about 0.5 to about 8.0 times, and preferably from about 1.0 to about 5.0 times, and most preferably, from about 1.5 to about 2.5 times the amount of surfactant used in the sister. A cleaning that comprises carbon dioxide. Frequently, the polar solvent is used so that the reverse micelles can be formed within the cleaning system. Reverse micelles are frequently formed because the surfactant has a carbon dioxide-phyllic portion and a carbon dioxide-phobic portion, wherein the carbon dioxide-phobic portion is dissolved in a resultant polar solvent core (e.g. water) of the resulting inverse ice. When the soiled fabric (which requires dry cleaning) comprising a portion with a mixture with more than about 40.0% acetate, a portion comprising about 100% acetate, or both, is cleaned via this invention, such cleaning can take place in a solvent such as a hydrocarbon or a solvent comprising silicon. There is generally no limitation with regard to the type of hydrocarbon which is used to clean the dirty laundry genre, which comprises a portion with a mixture with more than about 40.0% acetate or a portion with about 100% acetate of this invention, except that the hydrocarbon may be used in a dry cleaning machine to clean fabrics. Such a hydrocarbon includes a biodegradable functionalized hydrocarbon generally classified as an azeotropic solvent. The azeotropic solvent frequently comprises alkyl glycol alkyl ethers, such as propylene glycol butyl tertiary ether, and is described in U.S. Pat. 5,880,250, the disclosure of which is incorporated herein by reference. Moreover, as used herein, the hydrocarbon functionalized with biodegradable hydrocarbon is defined as meaning a biodegradable hydrocarbon comprising at least one member selected from the group consisting of an aldehyde., ketone, alcohol, alkoxy, ester, ether, amine, amide and group comprising sulfur. Other hydrocarbons, which may be used in this invention include aliphatic and aromatic hydrocarbons, and esters and ethers thereof, in particular mono and di-esters and ethers (eg, Exxon [sopar L, Isopar M, Isopar V, Exxon Exxsol and especially Exxon DF 2000). These solvents are well known and are made commercially available by Exxon. It should be noted that the hydrocarbon, as used herein, is defined to include halogenated (substituted) hydrocarbon, such as perchlorethylene. However, although such halogenated hydrocarbon may be used in this invention, it is not preferred and is not required due to its impact (ie, the halogenated hydrocarbon as perchlorethylene) in the ambient. As for the solvent comprising silicon, which can be used in this invention, such a solvent is usually a commercially available cyclic siloxane-based solvent made available by Green Earth Cleaning, LLC. The cyclic siloxane based solvent is generally one having a flash point above about 65 ° C, with octamethyl cyclotetrasiloxane and decometyl cyclopentasiloxane being more preferred. A more detailed description of such a commercially available siloxane-comprising compound can be found in U.S. Pat. 5,942,007, which 3, description is incorporated herein by reference. A solvent comprising higher and preferred silicon, which may be used in this invention, includes that which is classified as oligomers comprising linear silicon. These oligomers are usually siloxanes with molecular weights (Mw) ranging from about 100 to about 3000. Such solvents comprising linear silicon are made commercially available by The General Electric Company and Dow Corning (e.g., Dow Corning 200 (R) Fluids). ). A more detailed description of the solvent comprising linear silicon, which can be used in this invention, can be found in the serial US patent application no. 09 / 449,896, the description of which is incorporated herein by reference. When the solvent employed (for implying soiled fabrics comprising acetate) is a hydrocarbon or solvent comprising silicon, the cleaning machine which can be used normally comprises a solvent tank, a cleaning tank, a distillation tank, a filter and solvent outlet. Such machines are well known and commonly used in dry cleaning installations with co-perchlorethylene and are described in U.S. Pat. 5 4,712, 392, the description of which is incorporated herein by reference. It is noted that it is preferred for clothing comprising a portion with a mixture with more than about 40.0% acetate not being cleaned with carbon dioxide. However, if desired (but not required), this lower acetate limit can be increased to a The genus with a portion having more than about 70.0% by weight of acetate (this increase may be desired because genera comprising acetate tend to shrink more as the amount of acetate increases). In addition, it is preferred that the second portion of dirty laundry fabric be cleaned with a technique that does not comprise 15 carbon dioxide. However, if desired, a technique with from approximately more than zero and up to about 5.0% carbon dioxide (based on the total weight of solvent) can be used to clean the second portion of the dirty laundry fabric. It is further noted that if desired (but not required), the lower acetate limit 20 can be decreased to 25.0%, if limited gender shrinkage is not a detriment. With regard to the ordinary laundry accumulated via this laundry business, such an ordinary laundry can be washed in conventional machines, for example, made by Whirlpool and Maytag. The ---. Preferred detergents used when the ordinary laundry is washed via This invention is all, Wisk and Surf, all made commercially available by Unilever. In addition, industrial laundry machines using detergents made commercially available by DiverseyLever can be employed. The following examples are provided to illustrate and facilitate an understanding of the present invention. Accordingly, the examples are not intended to be limiting and it is intended that modifications falling within the scope and spirit of the claims be within the scope and spirit of the present invention.

The three (3) samples that were cleaned in carbon dioxide were placed in a cleaning chamber of a dry cleaning unit suitable for cleaning with carbon dioxide. The dry cleaning unit was constructed in a manner described in U.S. Pat. 5,467,492. Carbon dioxide was circulated in the machine at a rate of approximately 490 liters of liquid C02 per cleaning circuit, and a storage tank was used to feed the unit with clean carbon dioxide. The cleaning cycle lasted for about 15 minutes and the carbon dioxide was pressurized to approximately 59,755 kg / cm2 at 10 ° C. Subsequent to the cycle of After cleaning, the liquid was circulated back to the storage tank and the samples were removed. The data in Table I I show the percentage of dimensional change of the acetate genera after cleaning with carbon dioxide. When the three (3) samples were dry cleaned in Exxon 2000, a commercial establishment with a commercially available Union Union dry cleaning machine was used and all cleaning conditions were as required by the State of New Jersey. The machine was loaded with acetate comprising fabrics and cleaned at a temperature of approximately 27 ° C. Subsequent to the impieza cycle, which lasted approximately 45 minutes, the samples were heated to approximately 40 ° C for approximately 2 minutes to evaporate any solvent.
