CLEANING METHOD FOR TEXTILE FABRICS

Abstract: The present invention provides a more effective method of treating a spot or stain on a textile fabric, the method comprising the steps of: applying a detergent composition to the spot or stain; placing an absorbent layer adjacent to one side of the textile fabric in the region of the spot or stain; and applying heat, pressure, or heat and pressure, to the opposing side of the textile fabric in the region of the spot or stain, preferably in the presence of a hydrophilic solvent, or water, so that some or all of the spot or stain is absorbed into the absorbent layer. The detergent composition can be applied to the textile fabric using a container having a cap to which a foam pad is secured. The cap has a small opening through which the detergent composition can pass.

Description: CLEANING METHOD FOR TEXTILE FABRICS The present invention relates to a method of removing spots and stains from textile fabrics. Some stains are not always effectively removed by conventional laundry cleaning processes, for example in a washing machine. Such stains may be more effectively removed by pre-treatment, which herein means a cleaning treatment carried out before the conventional laundry cleaning process; and/or by post-treatment, which herein means a cleaning treatment carried out after the conventional laundry cleaning process. The present invention is concerned with a post-treatment cleaning method. EP200807, published on 12th November 1986, discloses an iron intended for cleaning clothes during ironing, i.e. a post-treatment. To achieve this objective the housing of the iron can be adapted with a recess to receive a brush (page 3, line 22 to page 4, line 1) . The iron is also provided with vacuum cleaning means. There is no suggestion that cleaning compositions could be used to enhance the cleaning method. US3748268, published on 24th July 1973, discloses spot and stain removing detergent compositions. The compositions are intended primarily for cleaning carpets, although textile fabrics are also mentioned The patent suggests that a pre-treatment cleaning method comprising gentle rubbing action may be used to help work the detergent composition into the stain, followed by stain removal using a dry absorbent cloth. Water is then applied to complete the cleaning operation. optionally using an absorbent material to remove the soil and composition remnants. Many textile fabrics, however, especially those made from silk or wool, are much more delicate them carpets. What may be considered as a gentle rubbing action when applied to a carpet could be considered as a harsh rubbing action when applied to a textile fabric. The very gentle treatment that is acceptable for delicate fabrics, however, may result in incomplete removal of stains. DE-A-43 03 454, published on llth August 1994, describes a process for stain removal and a stain removal set. The process comprises the steps of applying a sts.in remover to a stain which is then activated and washed out with hot water. The hot water is applied by means of heating water in a sponge using a hot iron. This cleaning process results in water being applied to a large area of the fabric, i.e. and area corresponding at least to the area of the sponge, which can result in fresh, greasy stains being spread over the fabric rε.ther than being removed. Furthermore, the presence of the sponge between the fabric and the iron prevents the heat from effectively reaching the region of the spot or stain. Simply applying more heat from the iron results in scorching or melting the sponge. The object of the present invention is to provide a more effective method of treating a spot or stain on a textile fabric comprising the steps of: applying a detergent composition to the spot or stain; placing an absorbent layer adjacent to one side of the textile fabric in the region of the spot or stain; and applying heat, pressure, or heat and pressure so that some or all of the spot or stain is absorbed into the absorbent layer. It is a further object of the present invention that the textile fabric should be dry and ready to wear at the end of the cleaning method. Summary of the Invention The object of the invention is achieved by applying the heat and/or pressure to the opposing side of the textile fabric in the region of the spot or stain preferably in the presence of a hydrophilic solvent or water. Without wishing to be bound by theory it is believed that the application of heat and/or pressure improves the cleaning efficiency by modifying the physical characteristics, such as viscosity, which promotes better penetration of the detergent composition into the stain, thereby improving cleaning efficiency. Furthermore the application of heat evaporates any residual water leaving the textile fabric dry. In a preferred embodiment of the invention a method of treating a spot or stain on a textile fabric is provided comprising the steps of: (a) applying a detergent composition to the spot or stain and placing an absorbent layer adjacent to the textile fabric in the region of the spot or stain and a first means for transferring some or all of the spot or stain into the absorbent layer; and subsequently (b) applying a hydrophilic solvent, or water, to the textile fabric in the region of the spot or stain and placing an absorbent layer adjacent to the textile fabric in the region of the spot or stain and a second means for transferring some or all of the spo': or stain into the absorbent layer. The second means for transferring the stain to the absorbent layer is preferably by applying heat, more preferably by using a hand-held domestic iron. The first means for transferring some or all of the spot or stain, preferably comprises the step of rubbing, pressing or brushing the spot or stain.

Detailed Description of the Invention A most preferred cleaning method comprises the steps of : (a) applying a detergent composition to a spot or stain and placing an absorbent layer adjacent to the textile fabric in the region of the spot or stain and a first means for transferring some or all of the spot or stain into the absorbent layer; and subsequently (b) applying a hydrophilic solvent, or water, to the textile fabric in the region of the spot or scain and placing an absorbent layer adjacent to the textile fabric in the region of the spot or stain and the step of applying heat to the textile fabric in the region of the spot or stain. The application of heat or pressure, or both, may be achieved by any means, but is most preferably achieved by a hand-held device such as an iron. A conventional iron having a hot-plate fixed to a body is a highly preferred hand held device. The hot¬ plate is heated most commonly by electrical means, and may have a means for controlling the temperature. A supply of water or steam may also be provided by the iron. Most preferably the absorbent layer is placed on a flat surface, such as an ironing board, and the stained or soiled textile fabric is laid flat on top of, and in contact with, the absorbent layer. The iron can then be easily applied to the textile fabric in the region of the stain or spot in order to ensure complete, or substantially complete, transfer of the stain or spot into the absorbent layer. The iron is preferably operated at a temperature of from 40°C to 180"C. An alternative device for applying heat or pressure is a heated roller or any other heated applicator. The roller or applicator may also be provided with a supply of the detergent composition. Suitable applicators include a steam iron with suction brush attachment, such as that disclosed in EP-A-0 493 348, and a thermoelectric applicator, such as that disclosed in EP-A-0 552 397. Also suitable is a steam iron with atomiser, such as that disclose in EP-A-0 629 736 wherein the detergent composition may optionally be stored in the iron and delivered directly onto the textile fabrics by means of the atomiser. Without wishing to be bound by theory it is believed that hydrophobic stains are first rendered hydrophilic by applying a detergent composition, optionally with a gentle rubbing action; water is then applied to the stain, again, optionally with a gentle rubbing action. The stain is removed by laying the stained fabric adjacent to an absorbent layer. The stain, which has been rendered more hydrophilic by the treatment, is transferred to the absorbent layer. Textile fabrics are any materials made from cloth, including garments such as shirts, blouses, socks, skirts, trousers, jackets, underwear etc, and also including tablecloths, towels, curtains etc. The definition of textile fabrics as used herein does not include carpets and similar floor coverings.

C6-C8 alkyl sulphonates, C6-C8 alkyl sulphates, C6-C8 alkyl ethoxy sulphates, C6-C10 betaines or C6-C10 amine oxides could also be useful. Long-chain surfactants useful in the detergent compositions of the present invention include the following. Water-soluble salts of the higher fatty acids, i.e., "soaps", are useful anionic surfactants in the compositions herein. This includes alkali metal soaps such as the sodium, potassium, ethanolamine, ammonium, and alkylammonium salts of higher fatty acids containing from about 8 to about 24 carbon atoms, and preferably from about 12 to about 18 carbon atoms. Soaps can be made by direct saponification of fats and oils or by the neutralization of free fatty acids.

Water-soluble nonionic surfactants are also useful as surfactants in the compositions of the invention. Indeed, preferred processes use anionic/nonionic blends. Such nonionic materials include compounds produced by the condensation of alkylene oxide groups (hydrophilic in nature) with an organic hydrophobic compound, which may be aliphatic or alkyl aromatic in nature. The length of the polyoxyalkylene group which is condensed with any particular hydrophobic group can be readily adjusted to yield a water-soluble compound having the desired degree of balance between hydrophilic and hydrophobic elements. Suitable nonionic surfactants include the polyethylene oxide condensates of alkyl phenols, e.g., the condensation products of alkyl phenols having an alkyl group containing from about 6 to 16 carbon atoms, in either a straight chain or branched chain configuration, with from about 4 to 25 moles of ethylene oxide per mole of alkyl phenol. Preferred nonionics are the water-soluble condensation products of aliphatic alcohols containing from 8 to 22 carbon atoms, in either straight chain or bra.nched configuration, with from 1 to 25 moles of ethylene oxide per mole of alcohol, especially 2 to 7 moles of ethylene oxide per mole of alcohol.

Enzymes can also be incorporated into the composition of the present invention. The composition of the present invention can contain neutral or alkaline salts which have a pH in solution of seven or greater, and can be either organic or inorganic in nature. While some of the salts are inert, many of them also function as detergency builder materials in the laundering solution. Examples of neutral water-soluble salts include the alkali metal, ethanolamine, ammonium or substituted ammonium chlorides, fluorides and sulfates. The sodium, ethanolamine and ammonium salts of the above are preferred. Citric acid and, in general, any other organic or inorganic acid may be incorporated into the present invention.

Bleaching agents may also be useful in the method of the present invention for treating bleachable stains . The bleaching agents may be incorporated into the compositions described above, or may be added as separate bleaching compositions. Peroxide bleaching agents are most preferred. Absorbent layers As used herein, the term "absorbent layers" refers to materials which absorb and contain fluids. The absorbent layer may be any absorbent means which is generally compressible, conformable, and capable of absorbing and retaining liquids. The absorbent pad may be manufactured in a wide variety of sizes and shapes (e.g., rectangular, round, asymmetric, etc.) . Examples of suitable absorbent materials include comminuted wood pulp, creped cellulose wadding; meltblown polymers; chemically stiffened, modified or cross-linked cellulosic fibers; tissue including tissue wraps and tissue laminates; absorbent foams; absorbent sponges; superabsorbent polymers; absorbent gelling materials; or any equivalent material or combinations of materials. The configuration and construction of the absorbent pad may also be varied (e.g., the absorbent pad may have varying caliper zones, a hydrophilic gradient, a superabsorbent gradient, or lower average density and lower average basis weight acquisition zones; or may comprise one or more layers or structures) . Further, the size and absorbent capacity of the absorbent pad may be varied. Optionally, the absorbent layer can include a backsheet which can be either liquid permeable (poly film) or not (e.g. non-woven, too) .If the backsheet is a poly film, the following applies : The poly backsheet is positioned on the bottom surface of the absorbent pad and is preferably joined thereto by attachment means such as those well known from the manufacture of disposable articles. For example, the backsheet may be secured to the absorbent pad by a uniform continuous layer of adhesive, a patterned layer of adhesive, or an array of separate lines, spirals, or spots of adhesive. Adhesives which have been found to be satisfactory are manufactured by H. B. Fuller Company of St. Paul, Minnesota and marketed as HL-1258. The attachment means will preferably comprise an open pattern network of filaments of adhesive as is disclosed in U.S. Patent 4,573,986 entitled "Disposable Waste-Containment Garment", which issued to Minetola et al. on March 4, 1986, more preferably several lines of adhesive filaments swirled into a spiral pattern such as is illustrated by the apparatus and methods shown in U.S. Patent 3,911,173 issued to Sprague, Jr. on October 7, 1975; U.S. Patent 4,785,996 issued to Ziecker, et al. on November 22, 1978; and U.S. Patent 4,842,666 issued to Werenicz on June 27, 1989. Alternatively, the attachment means may comprise heat bonds, pressure bonds, ultrasonic bonds, dynamic mechanical bonds, or any other suitable attachment means or combinations of these attachment means as are known in the art . The backsheet is impervious to liquids and is preferably manufactured from a thin, heat resistant, plastic film, although other flexible liquid impervious materials may also be used. The backsheet prevents the liquids absorbed and contained in the absorbent pad from wetting underlying materials. The backsheet may thus comprise a woven or nonwoven material, polymeric films such as thermoplastic films of polyethylene or polypropylene, or composite materials such as a film- coated nonwoven material . Optionally, the absorbent layer may include a topsheet or outer, protective layer. The topsheet is liquid pervious permitting liquids to readily penetrate through its thickness. Preferably, the characteristics of this outer protective layer includes : - that it be of appropriate design to substantially prevent loss or transfer of fibers of the inner sorbent material outwardly there through, - that it preferably possesses sufficient hea' transfer or heat sink characteristics, to inhibit tramsfer of sufficient heat through to the inner sorbent material to cause substantial melting thereof; and, - that it be relatively stable to heat from contact with a hot domestic iron or the like A suitable topsheet may be manufactured from a wide range of materials, such as porous foams; reticulated foams; apertured plastic films; or woven or nonwoven webs of natural fibers (e.g., wood or cotton fibers) , synthetic fibers (e.g., polyester or polypropylene fibers) , or a combination of natural and synthetic fibers. There are a number of manufacturing techniques which may be used to manufacture this topsheet; . For example, it may be a nonwoven web of fibers spunbonded, carded, wet-laid, meltblown, hydroentangled, combinations of the above, or the like. A preferred topsheet is carded and thermally bonded by means well known to those skilled in the fabrics art . A preferred topsheet comprises a web of staple length polypropylene fibers such as is manufactured by Veratec, Inc:., a Division of International Paper Company, of Walpole, Massachusetts under the designatiion P-8. Another usable non woven material is manufactured from Crown Zellerbach of Camas, under the trade nane Celestra. The absorbent structure is located between the topsheet and the backsheet, and might comprise these two as in integral element. It can be produced from a wide variety of liquid-absorbent materials, such as also commonly used in disposable hygienic articles, such as diapers, catamenials or Adult incontinence articles. Exemplary absorbent structures for use as absorbent layer as used in the disposable industry are described in U.S. Patent 4,610,678 entitled "High-Density Absorbent Structures" issued to Weisman et al. on September 9, 1986; U.S. Patent 4,673,402 entitled "Absorbent Articles With Dual-Layered Cores" issued to Weisman et al. on June 16, 1987; U.S. Patent 4,888,231 entitled "Absorbent Core Having A Dusting Layer" issued to Angstadt on December 19, 1989; and U.S. Patent 4,834,735, entitled "High Density Absorbent Members Having Lower Density and Lower Basis Weight Acquisition Zones", issued to Alemany et al. on May 30, 1989. Other absorbent pad designs are described in European Patent Application No.'s 93305150.0 and 93309614.1. Exemplary designs comprise the use of fibrous (e.g. cellulosic) materials in combination with "Superabsorbent materials", essentially hydrogel forming materials. Absorbent gelling materials are extensively used in absorbent hygiene articles such as diapers or sanitary napkins, due to their high absorption capacity for liquids, which may typically range from 15 g per gram to about 50 g/g. The gelling material is most often applied in particulate form in particle sizes ranging from 20 to 2000 micrometers. EP-A-0 407 838 discloses a gel-forming material for use in foodstuffs, which comprises a mixture of a crosslinked polymer and a non-crosslinked polymer for lump-free solution in water. EP-A-0 278 601 discloses a mixture of an absorbent gelling polymer, such as formed from water-soluble, ethylenically unsaturated monomers or crosslinked products thereof, including acrylic acid or a salt of acrylic acid as the main component, and inorganic material such as aluminia, or silica. The polymers in the mixture may be comprised of any combination of two or more chemically different types. The disclosed absorbent mixture is suited to absorb both low-viscosity and high-viscosity liquids. WO 91/12029 discloses an odor control composition comprising aggregated absorbent gelling material particles and zeolite material. The absorbent gelling material is made of hydrolized acrylonitrile grafted starch, acrylic acid grafted starch, polyacrylates, malice anhydride-based copolymers and combinations thereof. US patent No 4,333,464 discloses a sanitary napkin having water absorbent polymer which may comprise a mixture of two types of absorbent gelling material from the group consisting of starch, β-hydroxyethy acrylate, acrylonitrile, acrylic acid and acrylamide, carboxymethylcellulose, hydrophilic copolymer3 of acrylates, copolymers of a vinyl ester and an ethylenically unsaturated carboxylic acid and their saponification products, polyvinyl alcohol, and its derivatives. US patent no 4,902,544 discloses a flexible tibular casing comprising a crosslinked hydrocolloid .and naturally occurring cellulose such as saw dust, crushed corncobs, cottonlinters, wood pulp and the luce, ion- exchange resins or clay minerals. GB-B-1 544 002 discloses a mixture of a salt of an acrylic acid polymer and either guar gum, alginates or xanthan gum to provide an absorbent material with good absorbent properties, irrespective of the presence of an electrolyte in the liquid to be absorbed. Polyvalent ions may be incorporated in the absorbent composite. US patent no 4,411,660 discloses in an absorbent product two layers of absorbent material of different types, such that the upper layer gels slower than the first layer. European Patent Specification EP-B-0 401 189 discloses that favourable properties of absorbent products can be achieved by using two different types of absorbent gelling material in separate layers, rather than as a mixture of the two absorbent gelling materials in a single layer. The hydrogel-forming absorbent polymers useful in the present invention include a variety of substantially water-insoluble, but water-swellable polymers capable of absorbing large quantities of liquids. Such polymers materials are also commonly referred to as "hydrocolloids", or "superabsorbent" materials. These hydrogel-forming absorbent polymers preferably have a multiplicity of anionic, functional groups, such as sulfonic acid, and more typically carboxy, groups. Examples of polymers suitable for use herein include those which are prepared from polymerizable, unsaturated, acid-containing monomers. Thus, such monomers include the olefinically unsaturated acids and anhydrides that contain at least one carbon to carbon olefinic double bond. More specifically, these monomers can be selected from olefinically unsaturated carboxylic acids and acid anhydrides, olefinically unsaturated sulfonic acids, and mixtures thereof. Some non-acid monomers can also be included, usually in minor amounts, in preparing the hydrogel-forming absorbent polymers herein. Such non-acid monomers can include, for example, the water-soluble or water- dispersible esters of the acid-containing monomers, as well as monomers that contain no carboxylic or sulfonic acid groups at all. Optional non-acid monomers can thus include monomers containing the following types of functional groups: carboxylic acid or sulfonic acid esters, hydroxyl groups, amide-groups, amino groups, nitrile groups and quaternary ammonium salt groups. These non-acid monomers are well-known materials and are described in greater detail, for example, in U.S. Patent 4,076,663 (Masuda et al) , issued February 28, 1978, and in U.S. Patent 4,062,817 (Westerman) , issued December 13, 1977, both of which are incorporated by reference. Olefinically unsaturated carboxylic acid and carboxylic acid anhydride monomers include the acrylic acids typified by acrylic acid itself, methacrylic acid, ethacrylic acid, -chloroacrylic acid, a-cyanoacrylic acid, -methylacrylic acid (crotonic acid) , - phenylacrylic acid, -acryloxypropionic acid, sorbic acid, -chlorosorbic acid, angelic acid, cinnstmic acid, p-chlorocinnamic acid, -sterylacrylic acid, itaconic acid, citroconic acid, mesaconic acid, glutaconic acid, aconitic acid, maleic acid, fumaric acid, tricarboxyethylene and maleic acid anhydride. Olefinically unsaturated sulfonic acid monomers include aliphatic or aromatic vinyl sulfonic acids such as vinylsulfonic acid, alkyl sulfonic acid, vinyl toluene sulfonic acid and styrene sulfonic acid; acrylic and methacrylic sulfonic acid such as sulfoethyl acrylate, sulfoethyl methacrylate, sulfopropyl acrylate, sulfopropyl methacrylate, 2-hydroxy-3-methacryloxypropyl sulfonic acid and 2-acrylamide-2-methylproparte sulfonic acid. Preferred hydrogel-forming absorbent polymers for use in the present invention contain carboxy groups. These polymers include hydrolyzed starch-acrylonitrile graft copolymers, partially neutralized starch- acrylonitrile graft copolymers, starch-acrylic acid graft copolymers, partially neutralized starch-acrylic acid graft copolymers, saponified vinyl acetate-acrylic ester copolymers, hydrolyzed acrylonitrile or acrylamide copolymers, slightly network crosslinked polymers of any of the foregoing copolymers, partially neutralized polyacrylic acid, and slightly network crosslinked polymers of partially neutralized polyacrylic acid. These polymers can be used either solely or in the form of a mixture of two or more different polymers. Examples of these polymer materials are disclosed in U.S. Patent 3,661,875, U.S. Patent 4,076,663, U.S. Patent 4,093,776, U.S. Patent 4,666,983, and U.S. Patent 4,734,478. Most preferred polymer materials for use in making hydrogel-forming particles are slightly network crosslinked polymers of partially neutralized polyacrylic acids and starch derivatives thereof. Most preferably, the hydrogel-forming particles comprise from about 50 to about 95%, preferably about 75%, neutralized, slightly network crosslinked, polyacrylic acid (i.e. poly (sodium acrylate/acrylic acid)) . As described above, the hydrogel-forming absorbent polymers are preferably slightly network crosslinked. Network crosslinking serves to render the polymer substantially water-insoluble and, in part, determines the absorptive capacity and extractable polymer content characteristics of the precursor particles and the resultant macrostructures. Processes for network crosslinking the polymers and typical network crosslinking agents are described in greater detail in the hereinbefore-referenced U.S. Patent 4,076,663, and in DE-A-4020780 (Dahmen) . Although the hydrogel-forming absorbent polymers can have a size varying over a wide range, specific particle size distributions and sizes are preferred. For purposes of the present invention, particle size is defined for hydrogel-forming absorbent polymers that do not have a large greatest dimension/smallest dimension ratio such as fibers (e.g., granules, flakes, or pulverulents) as the dimension of a precursor particle that is determined by sieve size analysis. Thus, for example, a hydrogel-forming absorbent polymer particle that is retained on a standard #30 sieve with 600 micron openings is considered to have a particle size greater than 600 microns, a hydrogel-forming absorbent: polymer particle that passes through the #30 sieve with 600 micron openings and is retained on a standard #35 sieve with 500 micron openings is considered to have; a particle size between 500 and 600 microns, and a hydrogel-forming absorbent polymer particle that passes through a #35 sieve with 500 micron openings is considered to have a particle size less than 500 microns. For preferred hydrogel-forming absorbent polymers useful in the present invention, the particles will generally range in size from about 1 micron to about 2000 microns, more preferably from about. 20 microns to about 1000 microns. Further, for purposes of this invention, the mass median particle size of the hydrogel-forming absorbent polymers is important in determining the chareicteristics and properties of the resultant particles. The; mass median particle size of a given sample of hydrogel- forming absorbent polymer particles is defined as the particle size that divides a sample in half on a mass basis. Instead of the mass median particle si e, the mass average particle size could be specified as a measure for the dimension of the particles, wherein the mass average particle size is the average particle size of the sample on a mass basis. A method for determining the mass median particle size of a sample is described hereinafter in the Test Methods section. The mass median particle size of the hydrogel-forming absorbent polymer particles will generally be from about: 20 microns to about 1500 microns, more preferably from about 50 microns to about 1000 microns. For preferred hydrogel-forming absorbent polymers useful in the present invention, the particles have a mass median particle size less than about 1000 microns, more preferably less than about 600 microns, most preferably less than about 500 microns. The particle size of materials having a large greatest dimension/smallest dimension such as fibers is typically defined by their largest dimension. For example, if hydrogel-forming absorbent polymeric fibers are used in the present invention, the length of the fibers is used to define the "particle size." (The denier and/or the diameter of the fibers can also be specified.) For exemplary embodiments of hydrogel- forming absorbent polymers useful in the present invention, the fibers have a length greater than about 5 mm, preferably between about 10 mm and about 100 mm, more preferably between about 10 mm and about 50 mm. Preferred hydrogel-forming absorbent polymer particles of the present invention are those which exhibit a high absorptive capacity or Teabag Centrifuge Capacity value. Absorptive capacity, or Teabag Centrifuge Capacity, refers to the capacity of a given polymer to absorb liquids with which it comes into contact under free-swelling conditions. TCC can vary significantly with the nature of the liquid being absorbed and with the manner in which the liquid contacts the polymer material . For purposes of the present invention, Teabag Centrifuge Capacity is defined in terms of the amount of 0.9 % saline solution absorbed by any given polymer in terms of grams of saline solution per gram of polymer material in a Tea bag Centrifuge Capacity test procedure hereinafter defined in the Test Methods section. Preferred hydrogel-forming absorbent polymer particles of the present invention are those which have Teabag Centrifuge Capacity values of at least about 20 grams, more preferably at least about 25 grams, of saline solution per gram of polymer material. Typically, the hydrogel-forming absorbent polymer particles useful herein have Teabag Centrifuge Capacity values of from about 20 grams to about 70 grams of saline solution per gram of polymer. Mixtures of hydrogel-forming absorbent polymers particles having this relatively high absorptive capacity characteristic are especially useful in the present invention since the resultant absorbent member formed from such particles can, by definition, hold desirably high amounts of fluid. Other Absorbent structures for current absorbent pads can use of particulate Superabsorbent materials as described above, but forming a coherent stiucture from these. Such "Porous, absorbent polymeric macrostructures and methods of making same" are described in US patent 5,124,188 /WO 91/15362 assigned to Roe et al. Alternatively, Superabsorbent highly absorbent foam materials suitable for use in current invention are described in US patent 5.328.935 and 5.338.766, assigned to Trokhan and Phan. Alternatively, "Absorbent Foam Materials for aqueous body fluids and absorbent articles containing such materials" as described in US patent 5.268.224 assigned to DesMarais et al. are suitable for current application, too Optionally, the absorbent structure may include some specialized materials developed to absorb oils and greases. One example of this is T-151 oil sorbent, a 3M product, (Minnesota Mining and Manufacturing, ST. Paul, Minnesota) , T-151 absorbent and similar absorbent materials are typically non-woven polymeric fiber webs and include certain polyolefin polymers such as polypropylene, polyethylene, poly-4-methylpentene, arylene, styrene, and copolymers thereof, as well as polyesters, polyamides, and polycarbonates. Methods Teabag Centrifuge Capacity Test The Teabag Centrifuge Capacity test measures the Teabag Centrifuge Capacity values, which are a measure of the retention of liquids in the gelling material at hydrostatic pressure The superabsorbent material is placed within a "teabag", immersed in a 0.9 % by weight sodium chloride solution for 20 minutes, and then centrifuged for 3 minutes. The ratio of the retained liquid weight to the initial weight of the dry superabsorbent material is the absorptive capacity of the superabsorbent material. 21 of 0.9% by weight sodium chloride in distilled water is poured into a tray having dimensions 24cm x 30 cm x 5cm. The liquid filling height should be about 3cm. The teabag pouch has dimensions 6.5cm x 6.5cm and is available from a company called Teekanne in Dϋsseldorf, Germany. The pouch is heat sealable with a standard kitchen plastic bag sealing device (e.g. VACUPACK 2 PLUS from Krups, Germany) . The teabag is opened by carefully cutting it partially, and is then weighed. A 0.200g +/- 0.005g sample of the superabsorbent material is placed in the teabag. The teabag is then closed with a heat sealer. This is called the sample teabag. An empty teabag is sealed and used as a blank. Each teabag is then held horizontally, and the sample teabag is shaken so as to distribute the superabsorbent material evenly throughout the bag. The sample teabag and the blank teabag are then laid on the surface of the saline solution, and submerged for about 5 seconds using a spatular to allow complete wetting (the teabags will float on the surface of the saline solution but are completely wetted) . The timer is started immediately. After 20 minutes soaking time the sample teabag and the blank teabag are removed from the salir.e solution, and placed in a Bauknecht WS130, Bosch 772 NZK096 or equivalent centrifuge (230 mm diameter) , so that each bag sticks to the outer wall of the centrifuge basket. The centrifuge lid is closed, the centrifuge is started, and the speed increased quickly to l,400rpm. Once the centrifuge has been stabilised at l,400rpm the timer is started. After 3 minutes, the centrifuge is stopped. The sample teabag and the blank teabag are removed and weighed separately. The Teabag Centrifuge Capacity (TCC) for the sample of superabsorbent hydrogel-forming material is calculated as follows: TCC = [ (sample teabag weight after centrifuging) - (blank teabag weight after centrifuging) - (dry superabsorbent hydrogel- forming material weight)] ÷ (dry superabsorbent material weight) . Mass median particle size determination The particle size distribution of superabsorbent material is determined by placing a known weight of a sample in a Retsch mechanical sieving device, and shaking for a specified period of time under defined conditions. Sample sections that are retained on each sieve and the bottom pan are weighed and reported as percentages of the original sample weight. lOOg +/- 0.5g of dry superabsorbent polymeric material is weighed into a sample sup which is then closed by a lid. Four sieves are nested from bottom to top as follows: stainless steel bottom pan, No. 325, No. 100, No. 50 and No. 20; these being numbers of the U.S. sieve series (ASTM-E-11-61) . The sample is transferred to the upper most of the series of sieves, and the powder is distributed evenly around the screen. A stainless steel cover is places on the No. 20 sieve. The nested sieves are placed in position on a Retsch testing sieve shaker Vibotronic Type VEl with timer. It is ensured that the Retsch lid fits a s tightly as possible against the top of the shaker. The timer is set for 10 minutes, and started to begin the test. When the shaker has stopped, the nest of sieves is removed from the shaker. Each of the sieve fractions retained by the sieve is then weighed, for example by different measurements, to the nearest O.Og. It is important to work quickly in this test to avoid moisture pickup by the superabsorbent material . The mass median particle size of a given sample of hydrogel-forming absorbent polymer particles is defined as the particle size that divides the sample in half on a mass basis, i.e., one-half of the sample by weight will have a particle size less than the mass median size and one-half of the sample will have a particle size greater than the mass median size. A standard particle- size plotting method (wherein the cumulative weight percent of the particle sample retained on or passed through a given sieve size opening is plotted versus sieve size opening on probability paper) is typically used to determine mass median particle size when the 50% mass value does not correspond to the size opening of a U.S.A. Standard Testing Sieve. These methods for 30 determining particle sizes of the hydrogel-forming absorbent polymer particles are further described in U.S. Patent 5,061,259 (Goldman et . al) , issued October 29, 1991, which is incorporated by reference.

Example 99 A set of silk and wool swatches (50mm square) were soiled with make-up and tomato sauce. The stain was left to age for a day, in the dark, at normal room temperature (ca. 20°C, 60%RH) . Each soiled swatch was cleaned by the following method. 1. A non-linting sheet is prepared using a non-woven, two-ply fabric stock comprising polyester fibres, calliper 0.25 to 0.34 mm, basis weight 84g/m 2 . The fabric is cut into a 100 cm 2 sheet, 10 cm on a side. 10 g of the composition of example 19 are applied by dipping the composition onto the substrate, followed by squeezing with a roller. A hand-held spot removal device as shown in Figure 10 is prepared using conventional plastic injection molding techniques and apparatus. The arms which comprise the connecting means are fashioned from polypropylene, about (0.48 cm) in thickness. The connecting meanεi may each have a uniform width of about (1.9 cm), or can be shaped to provide a more aesthetically pleasing aspect by gently narrowing the connecting means to a width of about (1.27cm) at the bend shown in the Figure. The overall length of the device is about (13.34 cm) . The diameter of the base of each treatment member is about (3.33 cm) and the diameter of the region of the looped protrusions extending outwardly from each treatment member is about (2.86 cm) . Due to the angle of the bend between the arm;3 of the connecting means and the resiliency of the polypropylene, the gap between the first and second treatment members is about (1.59 cm) when the device is at rest. When squeezed by hand pressure, the gap is easily closed such that the protrusions which extend from each treatment members are brought into contact with opposite sides of the stains on the fabrics being treated. With respect to the multiple protusions which comprise the first and second treatment member, in this device the protrusions comprise stiff, looped monofilament fibers which extend from the face of each treatment member for a distance of about 2.0 mm. The soiled area is moistened with cleaning composition by gently dabbing it with a sheet article of the foregoing type. Once moist, a device of the type shown in Figure 10 is placed at the stained area, with the treatment members on either side of the fabric area of staining. The device is squeezed 10-30 times, slowly, to bring the illustrated looped protuberances into close contact with the fabric, thereby loosening the stain without damaging the fabric surface. The area is then again padded with the sheet article. 2. The stained area was then placed directly upon a slip of absorbent paper (the paper used was a sheet of kitchen paper towel) . 3. 1 ml of water was sprayed on the stained area, and pressure and heat were applied using an iron set at a temperature of 40°C for 15 seconds. A typical ironing pressure, as normally used for removing wrinkles in fabrics, was used. 4. Step 3 was repeated with a further 2 ml of water. 5. The swatch was then dried and smoothed. 60 The method of cleaning was repeated on stained swatches using the spot cleaning device of Figure 8 to 9 in place of the spot cleaning device of Figure 10.
