SURFACE CARE COMPOSITIONS AND METHODS FOR TREATING SURFACES

Field of the Invention

The present invention relates to a process of treating a new and/or cleaned surface, preferably fabπc surface, to impart soil release properties thereto and to the corresponding surface care, preferably fabπc care treatment compositions.

Background of the invention

Treatments of fibers and fabπcs compπsed of fibers pπor to or after cleaning (washing, dry cleaning, etc.) of such fibers and/or fabπcs are known m the textile and fϊber/fabπc-treatmg industries. Examples of such known treatments are sizing treatments, which are typically applied to fibers pπor to being woven mto fabπc, and finishing treatments, which are typically applied to fabπcs (woven fabπcs) or already processed textiles.

Finishing treatments can be permanent, semi-permanent (i.e., more than one, typically more than 2 domestic wash cycles are needed to substantially remove the finishing treatment, m other words reapphcation of the finishing treatment is not necessary after each wash) or non- permanent (temporary) (i.e., one domestic wash cycle substantially removes the finishing treatment, m other words, reapphcation of the finishing treatment is necessary after each wash). Permanent and or semi-permanent finishing treatments typically compπse resms. Examples of permanent finishing treatments are permanent press, flame retardation and/or water resistance. Typical permanent finishing treatments Examples of non-permanent finishing treatments include softening treatments applied to fabπcs and/or starching (stiffening) treatments applied to fabπcs.

Conventional soil/stam release treatments applied to fabπcs have been less than completely effective Regardless of the cleaning process used (conventional home washing in washing machine, dry-cleaning, etc.) to clean a fabπc in need of cleaning, it is not always possible to entirely remove all of the soils and/or stains from the fabπc being cleaned. This problem is even more present with today's trend to move to lower wash temperature, lower water consumption and shorter wash cycles, mamly for economic and environmental reasons.

As a result, a frequently observed problem of today's cleaning processes is the incomplete soil and/or stam removal. Some visible examples of such incomplete soil and/or stam removal include, but are not limited to, soil lines, m particular, of body soil and airborne dust left on collars and cuffs of shirts, blouses, T-shirts, soil (e.g., clay) patches on socks (e.g., sports socks), tough food stains (e.g., bacon grease, tomato sauce, meat sauce, etc.), particulate (clay) stains, grass stains, ground soil, and body soil on underwear mateπal. Once the stams and/or soils have not been completely removed from the fabπc after the cleaning process (i.e., they have been set on the surface of the fabπc or have penetrated the porous regions of the fabπc), they are more difficult to remove due to the ageing effect. Therefore, fabπcs tend to grey and/or yellow due to the soil deposited and remaining on the fabπc. Repetitive use and cleaning of the garment under these conventional cleaning processes increases the intensity of the greying / yellowing to the point ultimately that the garment is unacceptable to the consumer for further use due to its discoloration and/or fading.

Current attempts to solve this problem are frequent re-washmg; additional pre-, post-treatment with extra mechanical action or detergent quantity, the use of solvent and/or dry cleaning However, these soluttons result in increased fabπc deteπoration and/or are more time-consuming and/or less environmentally friendly.

Detergent composition formulators have unsuccessfully attempted to address this problem by formulating detergent compositions with soil release polymers. Such soil release polymers do not wholly prevent the attachment of soil to the fabπc but hinder such attachment and renders the cleaning operation more successful. As a result of this hindrance rather than prevention, it is a logical step to increase the level of the soil release polymers in the detergent compositions However, by increasing the level of soil release polymers in the detergent compositions, the fabπc has a tendency to become stiffer, less desirable m appearance and handfeel characteπstics Thus the upper limit on the amount of soil release polymer is determined by economics and the resulting adverse effect on fabrics, 1 e., the appearance and handfeel of the fabric Fabπcs with a relatively heavy application of soil release polymer do not have the same desirable appearance and handfeel as fabπcs without soil release polymers Moreover, it is recognized in the art that the efficiency of soil release polymers differs with fabπc type.

Conventionally, fabπc care/softness formulators have been more concerned about the "feel", softness and physical properties of the fabπcs rather than soil release properties of the fabπcs. For example, such formulators have looked at fabπc care compositions compnsmg starch, polyvmyl alcohol and/or cellulose deπvatives in combination with other ingredients to impart a smooth surface (i.e , reduced friction) to fabπcs duπng ironing, a moderate feeling and/or skin touch to fabπcs, a reduction or depression of wrinkles after washing or drying fabπcs, improved tightening of fabπcs, body and/or stiffness to the fabπcs, and anti-redeposition properties to fabπcs.

Moreover, it has been surpπsmgly found that most of the pπor art carbohydrate finishes commonly used in the textile industry or detergent industry m a laundry process or finishing treatment, impart a particulate stain removal negative leading to an actual fixation of stains rather than improved removal. Indeed, without wishing to be bound by theory, it is believed that such conventional carbohydrate finishes have a high affinity for fabπc, especially cotton but as well for clay. Such high affinity results in particulate stam removal negative performance.

However, the pπor art fails to teach or suggest a sihcone- and starch-free fabπc care composition and treating process whereby a layer of film-forming polymer with a low affinity for the fabπc or other surface is deposited on the fabπc surface or other surface (e.g., clothing, fabπc curtains, fabπc wall papers, fabπc tablecloths, fabπc napkins, fabπc-covered furniture, carpet, upholstery, bed linens, etc ) fully or in discrete regions thereof, pπor to and/or after the fabπc is cleaned by a conventional cleaning process, and subsequently easily removed by any conventional cleaning process, such as washing and/or dry cleaning.

Accordingly, there is a need for a sihcone- and starch-free fabπc care composition and treating process employing the fabric care composition whereby a layer of film-forming polymer with a low affinity for the fabric is deposited on the fabπc surface fully or in discrete regions thereof, pπor to and/or after the fabπc is cleaned by a conventional cleaning process, and subsequently easily removed by any conventional cleaning process, such as washing and/or dry cleaning so that the fabπc is protected from stams which would otherwise come into contact with the fabπc surface but for the layer of film-forming polymer; a fabπc cleaning process that provides superior stam removal performance compared to conventional cleaning processes; a fabπc treating process whereby the fabπc is imparted soil release properties supeπor to conventional fabric treating processes; a fabπc care composition that provides supeπor stam removal perfomance compared to conventional stam removal compositions.

Preferably, the water content of the "concentrated" form is less than 40%, more preferably less than 30%, most preferably less than 20% by weight of the detergent composition.

The present invention also relates to film-formmg polymer-containmg fabnc care compositions incorporated into a spray dispenser to create an article of manufacture that can facilitate treatment of fabnc articles and/or surfaces with said compositions containing the film-formmg polymer and other optional ingredients at a level that is effective, yet is not discernible when dned on the surfaces. The spray dispenser compnses manually activated and non-manual powered (operated) spray means and a container containing the fabπc care composition. The articles of manufacture preferably are in association with instructions for use to ensure that the consumer applies sufficient film-formmg polymer to provide the desired benefit.

Preferably the articles of manufacture are in association with instructions for how to use the composition to treat fabncs correctly, to obtain the desirable fabπc care results, for example, improved color appearance and/or pill prevention and/or abrasion resistance, while at the same time providing improved cleaning benefits, including, e.g., the manner and/or amount of composition to be used, and the preferred ways of stretching and/or smoothing, if any, the fabncs. It is important that the instructions be as simple and clear as possible. Accordingly, the use of pictures and/or icons to assist in explaining the instructions is desirable.

Again, the composition is preferably packaged in association with instructions for use to ensure that the consumer knows what benefits can be achieved.

A preferred fabnc care composition for treating fabnc compnses an effective amount of one or more film-forming polymers, and optionally, perfume, fabnc lubπcants, adjunct fabπc shape retention polymers, lithium salts, hydrophilic plasticizers, odor control agents, antimicrobial actives and/or preservatives, surfactants, enzymes, or mixtures thereof. Other optional ingredients can also be added, e.g., antioxidants, chelatmg agents, e.g., aminocarboxylate chelatmg agents, heavy metal chelatmg agents, antistatic agents, insect and moth repelling agents, dye transfer inhibiting agents, dye fixative agents, colorants, suds suppressors, and the like, and mixtures thereof.

However, the composition may be applied by spraying the fabπc with the fabnc care composition pπor to and/or dunng ironing, if needed. The application can be done industnally by large scale processes on textiles and/or finished garments and clothings, or in consumer's home by the use of commercial product.

The fabnc care compositions herein can be made by any suitable process known in the art. Examples of such processes are descπbed in U.S. Pat. No. 5,576,282.

The fabnc care compositions of the present invention can be incorporated into a spray dispenser, or concentrated stick form that can create an article of manufacture that can facilitate the cleaning and/or fabπc care or conditioning of fabπc. If the spray treatment is a "pre-treat", which is followed by a wash cycle, then the spray treatment fabπc care compositions preferably compnse from about 0.01% to about 50% of film-formmg polymer by weight the of total fabnc care composition, more preferably from about 0 1% to about 3% of film-formmg polymer by weight of the total fabric care composition.

In the latter case, a bπef nnse, not a full wash cycle, is desirable after treatment. Such spray treatment compositions are typically packaged m a spray dispenser.

The spray-treatment compositions herein are typically packaged m spray dispensers. The spray dispensers can be any of the manually activated means for producing a spray of liquid droplets as is known m the art, e.g. tπgger-type, pump-type, non-aerosol self-pressuπzed, and aerosol-type spray means. It is preferred that at least about 70%, more preferably, at least about 80%, most preferably at least about 90% of the droplets have a particle size of smaller than about 200 microns.

The spray dispenser can be an aerosol dispenser. Said aerosol dispenser compnses a container which can be constructed of any of the conventional matenals employed in fabπcatmg aerosol containers. The dispenser must be capable of withstanding internal pressure in the range of from about 20 to about 110 p.s.i.g., more preferably from about 20 to about 70 p.s.i.g. The one important requirement concerning the dispenser is that it be provided with a valve member which will permit the wnnkle reducing composition contained in the dispenser to be dispensed in the form of a spray of very fine, or finely divided, particles or droplets. The aerosol dispenser utilizes a pressunzed sealed container from which the wnnkle reducing composition is dispensed through a special actuator/valve assembly under pressure. The aerosol dispenser is pressunzed by incorporating therein a gaseous component generally known as a propellant. Common aerosol propellants, e.g., gaseous hydrocarbons such as isobutane, and mixed halogenated hydrocarbons, are not preferred. Halogenated hydrocarbon propellants such as chlorofluoro hydrocarbons have been alleged to contnbute to environmental problems Preferred propellants are compressed air, nitrogen, inert gases, carbon dioxide, etc. A more complete descnption of commercially available aerosol spray dispensers appears in U.S. Pat. Nos.: 3,436,772, Stebbms, issued Apr.8, 1969; and 3,600,325, Kaufman et al., issued Aug. 17, 1971; both of said references are incoφorated herein by reference Preferably the spray dispenser can be a self-pressuπzed non-aerosol container having a convoluted lmer and an elastomeπc sleeve. Said self-pressuπzed dispenser compnses a liner/sleeve assembly containing a thm, flexible radially expandable convoluted plastic liner of from about 0.010 to about 0.020 inch thick, mside an essentially cyhndncal elastomeπc sleeve The lmer/sleeve is capable of holding a substantial quantity of odor-absorbmg fluid product and of causing said product to be dispensed. A more complete descnption of self-pressuπzed spray dispensers can be found in U.S. Pat. Nos.: 5,111,971, Winer, issued May 12, 1992; and 5,232,126, Winer, issued Aug. 3, 1993; both of said references are herein incorporated by reference. Another type of aerosol spray dispenser is one wherein a barπer separates the wnnkle reducing composition from the propellant (preferably compressed air or nitrogen), as is disclosed in U.S. Pat. No. 4,260,110, issued Apr. 7, 1981, incorporated herein by reference. Such a dispenser is available from EP Spray Systems, East Hanover, N.J.

More preferably, the spray dispenser is a non-aerosol, manually activated, pump-spray dispenser. Said pump-spray dispenser compnses a container and a pump mechanism which securely screws or snaps onto the container. The container compnses a vessel for containing the wnnkle reducing composition to be dispensed.

The pump mechanism compnses a pump chamber of substantially fixed, volume, having an opening at the inner end thereof. Within the pump chamber is located a pump stem having a piston on the end thereof disposed for reciprocal motion m the pump chamber. The pump stem has a passageway there through with a dispensing outlet at the outer end of the passageway and an axial mlet port located inwardly thereof.

The container and the pump mechanism can be constructed of any conventional matenal employed in fabricating pump-spray dispensers, including, but not limited to: polyethylene; polypropylene, polyethlyleneterephthalate; blends of polyethylene, vmyl acetate, and rubber elastomer. Other matenals can include stainless steel. A more complete disclosure of commercially available dispensing devices appears m: U.S. Pat.

Most preferably, the spray dispenser is a manually activated trigger-spray dispenser Said tπgger- spray dispenser comprises a container and a tngger both of which can be constructed of any of the conventional material employed m fabπcatmg tπgger-spray dispensers, including, but not limited to : polyethylene, polypropylene, polyacetal, polycarbonste, polyethylene-terephthalate , polyvmyl chloride, polystyrene, blends of polyethylene, vmyl acetate, and rubber elastomer Other matenals can include stainless steel and glass. The trigger-spray dispenser does not incorporate a propellant gas. The tπgger-spray dispenser herein is typically one which acts upon a discrete amount of the wnnkle reducing composition itself, typically by means of a piston or a collapsing bellows that displaces the composition through a nozzle to create a spray of thin liquid. Said tngger-spray dispenser typically compnses a pump chamber having either a piston or bellows which is movable through a limited stroke response to the tngger for varying the volume of said pump chamber. This pump chamber or bellows chamber collects and holds the product for dispensing. The tngger spray dispenser typically has an outlet check valve for blocking communication and flow of fluid through the nozzle and is responsive to the pressure mside the chamber. For the piston type tngger sprayers, as the tngger is compressed, it acts on the fluid in the chamber and the spnng, increasing the pressure on the fluid. For the bellows spray dispenser, as the bellows is compressed, the pressure increases on the fluid. The increase m fluid pressure m either tngger-spray dispenser acts to open the top outlet check valve. The top valve allows the product to be forced through the swirl chamber and out the nozzle to form a discharge pattern. An adjustable nozzle cap can be used to vary the pattern of the fluid dispensed.

For the piston spray dispenser, as the tngger is released, the spnng acts on the piston to return to its oπginal position. For the bellows spray dispenser, the bellows acts as the spnng to return to its onginal position. This action causes a vacuum m the chamber. The responding fluid acts to close the outlet valve while opening the inlet valve drawing product up the chamber from the reservoir.

Without wishing to be bound by theory, it is believed that the selected polymer of the present invention demonstrate relatively low affinity to the fiber surface in a cleaning situation and low soil permeability properties. Moreover, it is believed that compounds with no or little film forming properties and high surface affinity show poor stam release and a negative for particulate stam removal.

The selected film-forming polymer of the present invention, upon naturally drying, tumble drying and/or ironing forms a protective film on the fiber surface that provides a barner against stam and soil penetration into the fiber, incrustation, improves feel, helps ironing, and protects against wear and colour damage. Dunng the subsequent cleaning process, e.g. wash cycle and/or dry cleaning, the polymeπc film dissolves and loosens the soil/stain from the fabnc fiber. Such polymeπc film dissolution greatly facilitates the cleaning and provide supenor cleaning.

Adjunct Materials

The fabric care compositions of the present invention comprise an effective amount of the film-forming polymer, and preferably one or more of the above-described preferred ingredients, and optionally one or more of the following conventional cleaning adjunct materials either to improve the performance of the film-forming polymer, e.g., in the areas of wrinkle control, anti-wear, soil release, tensile strength and the like, or to provide additional benefits, such as odor control, antimicrobial, and the like. The useful optional cleaning adjunct materials are those that are compatible with the film-forming polymer, in that they do not interfere and/or substantially or significantly diminish the benefits provided by the film-forming polymer. The precise nature of these optional cleaning adjunct materials, and levels of incorporation thereof will depend on the physical form of the fabric care compositions, and the nature of the cleaning operation for which it is to be used.

Examples of such cleaning adjunct materials include, but are not limited to, the following.

Preservatives - The fabric care compositions herein may also optionally contain one or more preservatives. The function of the preservatives is to prevent organisms/micro-organisms from breeding and growing on the fabrics treated with the laundry detergent and/or fabric care compositions herein. In the absence of such preservatives, organisms/micro-organisms could grow on the fabrics treated with the laundry detergent and/or fabric care compositions herein because a significant amount of carbohydrates/sugar could remain on the fabrics after treatment. Samtization of fabrics can be achieved by the compositions of the present invention containing antimicrobial mateπals, e g , antibacteπal halogenated compounds, quaternary compounds, and phenolic compounds.

It is preferable to use a broad spectrum preservative, e.g., one that is effective on both bacteπa (both gram positive and gram negative) and fungi. A limited spectrum preservative, e.g., one that is only effective on a single group of microorganisms, e.g., fungi, can be used in combination with a broad spectrum preservative or other limited spectrum preservatives with complimentary and/or supplementary activity. A mixture of broad spectrum preservatives can also be used. In some cases where a specific group of microbial contaminants is problematic (such as Gram negatives), aminocarboxylate chelators may be used alone or as potentiators in conjunction with other preservatives. These chelators which include, e.g., ethylenediammetetraacetic acid (EDTA), hydroxyethylenediam etnacetic acid, diethylenetnammepentaacetic acid, and other aminocarboxylate chelators, and mixtures thereof, and their salts, and mixtures thereof, can increase preservative effectiveness against Gram-negative bactena, especially Pseudomonas species.
