The invention relates to cleaning agents for textile surfaces, especially textile floor coverings. The cleaning agents comprises a porous, pulverized support material made of urea-formal-dehyde resinous foam, which enriched with detergents.
Description
3~
1 Cleaning agents are known in which particles of a pulverized, porous, and water-insoluble inorganic material are com-bined with 60-80 parts by weight of an aqueous solution of low molec-ular weight alcohols and washing-promoting substances. Ground pumice stone, ground lime tuff, ground brick, ground expanded cement and silica gel have been used as the inorganic material. A disadvantage of these materials is that they have only a limited capacity Eor ab-sorbing the active ingredients.
. A further disadvantage of the inorganic materia]s is that the handling of them leads to the formation of dust. ~hen the re-moval of the dried cleaning agent by means of a commercial vacuum cleaner is attempted, the dust clogs the filter of the cleaner. Also, the very fine dust particles are dispersed in the air and harm the environment.
A further disadvantage of these inorganic materials is their abrasive effect on textile surfaces. Furthermore, these ma-terials tend to cover and smear the textile nap being treated.
; Because of their high specific weight, they are also difficult to remove.
Furthermore, a process for removing moist spots from textile materials is also known, in which a highly absorptive mater-ial made of urea cellular plastic with a density of ahout 18-20 kg/m3 is used. This plastic is to consist of a highly absorptive cellular block that is so brittle that particles of cellular plastic conti-nuously break off from the block when the block is rubbed over the textile.
A disadvantage of this method s that urea cellular plastic with a volume density of 18-20 kg/m is too light to be used over large surface areas of the textile when a mechanical device is used to work the plastic into the fibers, because the mechanical '7 1 device grinds the plastic into a fine powder.
A further disadvantage of this method is that because of the above mentioned problems with mechanical devices, it can only be carried out by hand, and is only applicable to individual spots The cleaning of an entire surface of a textile product, e.g., a rug, is not possible.
An object of the present invention is to provide a cleaning agent which avoids the disadvantages mentioned above and which can be used mechanically for surface cleaning in an effective manner.
It is a further object to combine tenside-(wetting agent) containing water adhering to the inside of a support material with a highly effective ingredient or combination of ingredients into an effective cleaning agent, especially for textile surfaces.
The support material comprises a comminuted plastic foam.
These objects and still others are solved by means of a plasticized urea-formaldehyde resinous foam acting as a support material. This support material should have a bulk density of 30-60 kg/m3, a pouring weight of 50-150 g/l and a particle size of 0.1 - 6 mm in its crushed (i.e., comminuted) state.
In further development of the invention, it is convenient that tenside-(wetting agent) containing water adhering to the urea-formaldehyde resinous foam constitutes up to 80% by weight and is stored homogeneously within the resinous foam. Examples of the tenside (wetting agent) are alkali salts of di-butyl naphthalene sulfonic acid, up to 3.0 percent by weight, in aqueous foaming solution.
An aqueous solution containing at least one of the fol-lowing active ingredients, in combination with the tenside-(wetting agent) containing water adhering to the inside of the resinous foam 1 constitutes the detergent:
0.1 - 0~5% by weight of an antistatic agent to promote the ability of the resin particles to be removed from the textile surface by suction; 0.1 - 2% by weight of a volatile alkali; and 0.5 - 5% by weight of a polymer-tenside-(surfactant) combination to prevent re-soiling of the textile fibers. The poly-mer may be, for example, an acrylate/styrene copolymer. The sur-factant may be, for example, salts of fatty alcohol sulfates such as lauryl sulfate, or ether sulfates as well as esters of sulfo-succinnic acid.
It is also convenient that the aqueous solution beapplied to the already manufactured plastic product.
In order that the cleaning agent treats the textile surface in a hygienically perfect manner, and allows the cleaning agent to be easily removed by means of a conventional vacuum cleaner, it may be important to add further agents, as, for example, low molecular weight alcohols, bactericides, perfumes, and the like to the detergent. It may also be important that the antistatic agent prevents the development of a static charge during the cleaning and lowers the binding forces between the cleaning agent residues and the textile fibers.
In order to avoid the so-called "filling effect", (i.e., filling of textile fiber interstices with cleaning material and the like), it is advisable that the polymer-tenside combination does not foam and that the re-soiling of the textile fiber is diminished.
An advantage of the presently disclosed combination is that it exhibits a uniform cleaning action, even on intensively soiled areas, without depositing dissolved dirt residues since the hydrophilic, capillary active plastic foam absorbs the loosened dirt particles extremely effectively.
1 A further advantage of the invention is due to the large inner surface area of the foamed plastic particles. The result-ing effect is to lower the drying time of such particulate cleaning agents below that of the values obtained previously for other so-called crushed cleaning agents. The dirt-laden support material of the present cleaning agent, which remains after drying, can be ad-vantageously removed along with the tenside and the dirt residues adhering to it by means of a conventional household vacuum cleaner, both completely and without problems.
The following example illustrates the use of the present invention further without in any way limiting it:
EXAMPLE
A urea-formaldehyde resinous foam block, previously prepared mechanically so as to have an unusually high density, is crushed (i.e., comminuted) mechanically to obtain particles having a slze of 0.1 6 mm. The foam block is prepared according to the usual process for making foamy materials for use in the construction ` industry and for mixing with soil for the growing of plants with a density of up to 25 kg/m . In the present application the foam is used as the support material with a density of 30-60 kg/m3. This high density is necessary for the stability of the comminuted ma-terial. SubsequentLy this support material which makes up 40-60%
of the weight of the final cleaning agent and contains up to 80%
by weight of tenside-containing water, is combined with a solution of at least one active ingredient. The concentrations of the active ingredients are homogeneously mixed with the tenside-contain-ing water contained in the support material. It should be noted that the thus-prepared cleaning agent will retain its pulverized character. The active ingredients may contain up to 5% by weight alcohol, 0.5 - 5% by weight polymer containing tenside, 0.1 - 2%
l't.~3 '~
1 by weight antifoaming agent, 0.1 - 0.5% by weight antistatic agent, 0.1 - 1% by weight perfuming agent, and 58-15% by weight water.
The volatile aLkali may be ammonia or one or more organ-ic amines. The antistatic agent may be polyglycol ether sulfate.
The alcohol may be methyl, ethyl, propyl, or butyl alcohol or their isomers. The perfuming agent may be an alcohol-soluble ethereal oil.
As previously mentioned a bactericide may also be added.
The bactericide may be amine-formaldehyde products, such as a cyclic amine acetate.
The thus-manufactured cleaning agent is brought into contact with the textile surface by, for example, being spread over it by hand. The cleaning agent is then worked into the textile fibers, e.g., by means of a commercially available floor care de-vice. Such devices usually have a mechanism which works the clean-ing agent into the textile fibers by means of an oscillating agita-tion. The solution of active ingredients and detergents separates from the support material due to the effect of the mechanical work-ing-in process. The liberated active ingredients then act on the dirt which exists in the te~tile, causing the dirt to be dissolved, loosened, dispersed, and emulsified. When this occurs, the dirt-laden active ingredients return to the carrier material, to be re-absorbed therein and bound. This occurs after the removal of the above-described cleaning device and the resulting beginning of the drying process. The physical properties of the hydrophilic resinous foam guarantee the absorption of the dirt-laden tensides.
It is also important to note that the surface area, due to the range of particle sizes, and especially the large surface area due to the inner foam structure of the particles, guarantees maximum absorption effectiveness.
:~C~ '7 1 In order that the above mentioned properties be obtained, an open cellular urea-formaldehyde resinous foam must be used. The resinous foam is so modified, that given a higher bulk density, a finer spectrum of particle sizes, and a capacity to contain tensides, antistatic agents, antifoaming agents, volatile alkali, perfumes, and the like, a cleaning agent capable of being mechanically worked into a textile is formed. Accordingly, it is necessary that the spectrum of particle sizes correspond to the specified values in order to ob tain a mechanical cleaning action in the textile and to guarantee the ability to effect subsequent removal of the dried, dirt laden support material by applying suction to it.
It will be understood that each of the elements de-scribed above, or two or more together, may also find a useful appli-cation in other types of a cleaning agent differing from the types described above.
While the invention has been illustrated and described as embodied in cleaning agents for textile surfaces based on urea-formaldehyde resinous foam, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
1 Cleaning agents are known in which particles of a pulverized, porous, and water-insoluble inorganic material are com-bined with 60-80 parts by weight of an aqueous solution of low molec-ular weight alcohols and washing-promoting substances. Ground pumice stone, ground lime tuff, ground brick, ground expanded cement and silica gel have been used as the inorganic material. A disadvantage of these materials is that they have only a limited capacity Eor ab-sorbing the active ingredients.
. A further disadvantage of the inorganic materia]s is that the handling of them leads to the formation of dust. ~hen the re-moval of the dried cleaning agent by means of a commercial vacuum cleaner is attempted, the dust clogs the filter of the cleaner. Also, the very fine dust particles are dispersed in the air and harm the environment.
A further disadvantage of these inorganic materials is their abrasive effect on textile surfaces. Furthermore, these ma-terials tend to cover and smear the textile nap being treated.
; Because of their high specific weight, they are also difficult to remove.
Furthermore, a process for removing moist spots from textile materials is also known, in which a highly absorptive mater-ial made of urea cellular plastic with a density of ahout 18-20 kg/m3 is used. This plastic is to consist of a highly absorptive cellular block that is so brittle that particles of cellular plastic conti-nuously break off from the block when the block is rubbed over the textile.
A disadvantage of this method s that urea cellular plastic with a volume density of 18-20 kg/m is too light to be used over large surface areas of the textile when a mechanical device is used to work the plastic into the fibers, because the mechanical '7 1 device grinds the plastic into a fine powder.

The concentrations of the active ingredients are homogeneously mixed with the tenside-contain-ing water contained in the support material. It should be noted that the thus-prepared cleaning agent will retain its pulverized character. The active ingredients may contain up to 5% by weight alcohol, 0.5 - 5% by weight polymer containing tenside, 0.1 - 2%
l't.~3 '~
1 by weight antifoaming agent, 0.1 - 0.5% by weight antistatic agent, 0.1 - 1% by weight perfuming agent, and 58-15% by weight water.
The volatile aLkali may be ammonia or one or more organ-ic amines. The antistatic agent may be polyglycol ether sulfate.
The alcohol may be methyl, ethyl, propyl, or butyl alcohol or their isomers. The perfuming agent may be an alcohol-soluble ethereal oil.
As previously mentioned a bactericide may also be added.
The bactericide may be amine-formaldehyde products, such as a cyclic amine acetate.
The thus-manufactured cleaning agent is brought into contact with the textile surface by, for example, being spread over it by hand. The cleaning agent is then worked into the textile fibers, e.g., by means of a commercially available floor care de-vice. Such devices usually have a mechanism which works the clean-ing agent into the textile fibers by means of an oscillating agita-tion. The solution of active ingredients and detergents separates from the support material due to the effect of the mechanical work-ing-in process. The liberated active ingredients then act on the dirt which exists in the te~tile, causing the dirt to be dissolved, loosened, dispersed, and emulsified. When this occurs, the dirt-laden active ingredients return to the carrier material, to be re-absorbed therein and bound. This occurs after the removal of the above-described cleaning device and the resulting beginning of the drying process. The physical properties of the hydrophilic resinous foam guarantee the absorption of the dirt-laden tensides.
It is also important to note that the surface area, due to the range of particle sizes, and especially the large surface area due to the inner foam structure of the particles, guarantees maximum absorption effectiveness.
:~C~ '7 1 In order that the above mentioned properties be obtained, an open cellular urea-formaldehyde resinous foam must be used. The resinous foam is so modified, that given a higher bulk density, a finer spectrum of particle sizes, and a capacity to contain tensides, antistatic agents, antifoaming agents, volatile alkali, perfumes, and the like, a cleaning agent capable of being mechanically worked into a textile is formed. Accordingly, it is necessary that the spectrum of particle sizes correspond to the specified values in order to ob tain a mechanical cleaning action in the textile and to guarantee the ability to effect subsequent removal of the dried, dirt laden support material by applying suction to it.
It will be understood that each of the elements de-scribed above, or two or more together, may also find a useful appli-cation in other types of a cleaning agent differing from the types described above.
While the invention has been illustrated and described as embodied in cleaning agents for textile surfaces based on urea-formaldehyde resinous foam, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.
Claims (8)
1. Cleaning agents for textile surfaces, comprising a support material composed of particles of comminuted plasticized urea-formaldehyde resinous foam having a bulk density of 30-60 kg/m3 and a pouring weight of 50-150 grams/liter, said particles having a particle size of 0.1-6 mm; and detergents enriching the support material particles, said detergents comprising tenside-(wetting agent) containing water adhering inside the urea-formaldehyde resinous foam particles, the tenside-containing water being stored homogeneously within the resinous foam particles in an amount of up to 80% by weight of the resinous foam particles; and an aqueous solution combining with the tenside-containing water, the aqueous solution containing at least one member from the group consisting of 0.1-2% by weight of a volatile alkali, 0.1-0.5% by weight of an antistatic agent to promote the ability of the resin particles to be removed from the textile surface by suction, and 0.5-5% by weight of a polymer-tenside-(surfactant) comhination to prevent resoiling of the textile fibers.
2. Cleaning agent as recited in claim 1, wherein the polymer of said polymer-tenside-(surfactant) combination is an acrylate/styrene copolymer.
3. Cleaning agent as recited in claim 1, wherein said surfactant is selected from the group consisting of salts of fatty alcohol sulphates, ether sulphates, and esters of sulfosuccinic acid.
4. Cleaning agent as recited in claim 3, wherein said salt of fatty alcohol sulphates is lauryl sulphate.
5. Cleaning agent as recited in claim 1, wherein the aqueous solution is combined with the pre-existing support ma-terial particles.
6. Cleaning agent as recited in claim 1, wherein the detergent further comprises at least one additive selected from the group consisting of at least one low molecular weight alcohol, at least one bactericide, and at least one perfuming agent.
7. Cleaning agent as recited in claim 1, wherein the polymer-tenside combination is non-foaming and re-soiling of the textile fibers is diminished.
8. Cleaning agent as recited in claim 1, wherein the antistatic agent prevents static charge from developing during the cleaning and lowers the adherence between the cleaning agent residues and the textile fibers.
