Powdered non-toxic cleaning agent for large areas

Interior textiles

The invention relates to a powdery non-toxic cleaning agent for the quick and thorough cleaning of carpets, Furniture textiles and other large-area interior decoration textiles.

When cleaning carpets, upholstery fabrics and textiles upholstered furniture in place presents significant practical difficulties.

The use of traditional releasing and cleaning products, which are in the form of anhydrous or aqueous liquids or foams, in fact, have serious disadvantages.

When using this type of product, a more or less complete, deep soaking of some or all Do not avoid fibers from which the treated textile fabric is built up, and this impregnation always has a certain migration or leaching the dyes and finishing agents as well as the formation of edges or sometimes even shrinkage or matting of the treated Textile fabric result.

In addition, the conventional liquid detergents leave behind the generally surface-active cleaning substances generally contain surfactant residues after drying on the fibers, which give the textile a matt appearance and a strong appearance

030025/0653

give increased tendency to re-soiling.

In addition, it takes time for those deeply impregnated with liquid to dry Fibers are always very long and represent a further significant disadvantage for the use of such products, especially in the case of transit points fixed carpets.

The present invention provides a new cleaning agent for carpets and furniture fabrics, which is those described above Does not have disadvantages and faster than the previously known products to a better cleaning of soiled in various ways Textile surfaces leads.

Powdered cleaning products for the care of textiles are already known. This is how the French patent describes No. 1 321 148 a with a mixture of carbon tetrachloride, trichlorethylene and gasoline impregnated urea / formaldehyde resin powder. Such a product can only be used pointwise on grease stains and has absolutely no cleaning power compared to more water-soluble ones Stains.

Next powder cleaning products that consist of a powder synthetic macromolecular substance such as polyurethane, polystyrene, polyethylene, polypropylene, polyvinyl and acrylic resins and the like with anhydrous or aqueous solvent mixtures impregnated thereon are in the French patents No. 2,015,972, 2,163,692 and 2,240,287, in the German patent application 2,021,677 and British Patent 1,251.

However, none of these products are capable of being completely satisfactory Ensure cleaning of all possible different types of soiling and the treated fabric to permanently give a new look.

030025/0653

Indeed, the previously known powdered products possessed a lower cleaning power than liquid products and also had the disadvantage that they were difficult to remove from the textile fabric afterwards were completely removable and tended to stick and stick to its surface.

Of these, anion-active surfactants are particularly advantageous usable: these are, for example, alkyl sulfonates, alkylbenzenes sulfonates, sulfosuccinic acid esters, fatty alcohol sulfates or

030025/0653

Alkylene oxide condensates of fatty alcohols of higher molecular weight, Fatty acid amides or propylene glycols with molecular weights between 900 and 4,000. The anionic surfactants in the form of their lithium salts are preferred.

The cleaning agents according to the invention preferably contain also a preservative, which can protect the finished product against microbial and fungus damage. The preservative is preferably introduced into the aqueous phase of (A): this can be chosen from all known microbicidal substances, such as sodium orthophenylphenolates, hexylresorcinol, methyl, propyl and benzyl parahydroxybenzoates, para-chloro-metacresol, Triethanolamine ortho-, meta- and parahydroxybenzoates, Dichloroacetamide and the like.

They can also contain antioxidants, for example Butylated hydroxyanisole, butylated hydroxytoluene, citric acid and Mixtures of these products.

The main characteristic of the powdery carrier (B) lies in its absorbency and in the mean size of the Particles that make it up.

The powdery carrier (B) is preferably capable of at least one 80 to 300 percent by weight of the liquid (A) to be absorbed, these proportions being based on the weight of the non-impregnated carrier.

The mean size of the particles which form the carrier is preferably between 5 and 1000 μl and particularly preferably between 50 and 300 μl.

In the prior art, numerous pulverulent carriers have already been described, which are produced by absorbing the inventive Solvent mixture (A) provide excellent cleaning agents

can.

Examples of such pulverulent carriers are mineral powders such as those made from oxidic minerals, natural or synthetic Alkali, alkaline earth and ammonium salts, and also, for example, aluminum oxide hydrates, silicon oxides, silicates, clays, glass beads, Carbonates, bicarbonates such as ammonium bicarbonate, borates, chlorides, phosphates, citrates, various sulfates and the like.

This also includes synthetic, solid, powdered, ethylene, propylene, styrene, acrylates, acrylonitrile, alkadienes, Amides, maleic anhydride, urea / formaldehyde and phenol / formaldehyde resins, Polyurethanes and similar resins made of polymers or various copolymers and polycondensation products.

This also includes the various powdered artificial cellulose materials, such as regenerated Celluloses and cellulose acetates.

The one preferred for the cleaning agents according to the invention However, the carrier is among organic natural substances of vegetable origin and among them in particular powders of wood-like substances, dehulled cereal flours and starch powders.

The carrier (B) of the cleaning agents according to the invention can in particular consist entirely of one or the other of these substances of vegetable origin, provided that the particle size of this substance and its absorbency correspond to the basic characteristics mentioned above.

The substance or substances of vegetable origin that can be used as the carrier (B) are selected, for example, from wood, cork and Grain husk flours, corn on the cob powders, brewer's grains, grain flours such as wheat, tapioca, corn, rice, rye, soy, barley,

030025/0653

Oatmeal and the like, and made from potatoes, wise men, arrowroot, oats, pick peas, beans, rice, corn, broad beans, rye, barley and the like extracted from starch powders.

A particularly absorbent carrier (B), which has excellent mechanical properties and an optimal cleaning effect of the cleaning agent according to the invention, includes:

(α) about 40 to 80% by weight of a woody vegetable matter preferably with a cell structure that is able to absorb at least 100 percent of its dry weight of solvent mixture (A),

(ß) about 5 to 20 parts by weight of a cereal flour and Z (γ) about 15 to 40 wt. -Z a starch powder,

where all parts by weight are based on the total weight of the

Refer to carrier (B).

Preference is given to those wood-like plant substances that are at the same time very hard and preferably have a cell structure, which allows the absorption or reversible absorption of larger proportions of liquid.

One in particular in the compositions according to the invention a valued woody substance is a corn cob powder; in fact, it has good hardness and a cellular structure at the same time allows the liquid (A) to be well absorbed and to release it quickly onto the fiber during the cleaning work.

The mean particle size of the wood-like substance (α) is preferably 100 to 300 yes, and the ideal mean dimensions are in the range of 150 and 200 μ.

In the course of the cleaning work, the woody plant matter particles exercise this size on the fiber of a mechanical one

030025/0653

Frictional effect, which without damaging the fiber surface Detachment of the contaminants facilitated by one or the other of the component (a) transferred from the carrier (B) to the fiber or (b) the solvent mixture is brought into solution and then immediately absorbed by this very carrier (B).

By the presence of a cereal flour a medium one Particle size, which is advantageously also between about 5 and 1000/1, but preferably between about 100 and 300> u, in the carrier (B) the properties of the inventive Cleaning agent effectively supplements by facilitating rapid and homogeneous distribution over the entire textile surface and the Removability of the solvent mixture after evaporation Powder lying on the fiber is considerably improved by the fiber.

The ideal mean particle size of the flour grains is preferably between the limits 125 and 280 yes. Among the cereal flours mentioned above, rice powder is particularly valuable in the detergents of the present invention because of its hardness, density and rounded shape of the particles of which it is composed.

The cleaning agents according to the invention also contain advantageously a strength that, because of its very special granular structure and its between 25 and 250 yes average particle size, the powder cleaning mixture has excellent mechanical properties, flowability, storage behavior and provides slip on the fibers without in any way increasing their adhesion to the fabrics.

The optimal mean particle size in the inventive Starch powder used in detergents is advantageous between 40 and 200/1.

030025/0653

The powdery carrier (B) according to the invention has the Advantage that it can soak up the entire solvent mixture (A) without losing its dry or semi-dry powder-like appearance, while maintaining its excellent flow properties, even after long periods of storage. This carrier has the further advantage that it does not clog vacuum cleaner bags and, above all, not to their Tearing leads.

In addition, the pulverulent carrier (B) has the advantage that it contains several, immiscible solvent components absorbs and then, after the absorbed material has come into contact with a textile, the greater part of it Release solvent components that can soak up and dry out contaminants, turning into a powder, its various particles in no way adhere to the textile fibers ^ and thus by simple brushing or with the help of a vacuum cleaner medium power can be easily removed.

The cleaning agents according to the invention are produced by that the whole powdery absorbent mixture (B) simply one after the other with small amounts of each solvent component impregnated and homogenized.

The powdery carrier (B) is preferably impregnated first with the homogeneous mixture consisting of the solvents (b) and then continue after evenly distributing the total amount the solvent (b) over this powder the water and the rest of the ingredients in successive small amounts until the powdery mixture is completely homogeneous.

After sieving, a dry, semi-dry or moist powder is obtained, which when applied to a textile surface does not dust and after drying can be removed from this carpet by brushing or vacuuming without raising dust.

030025/0653

For cleaning a textile surface or a carpet with Using a composition according to the invention one carries about 10 to 50 grams, preferably 25 to 40 grams, of the product per square meter of textile surface evenly and then distributes the product quickly by rubbing with the help of a broom over the entire surface of the carpet. After drying, the composition does not adhere at all on the carpet and can be vacuumed up immediately and easily with the help of a medium-powered vacuum cleaner without leaving any traces; the carpet treated in this way looks clean, fluffy and new.

The use of a composition according to the invention shows numerous advantages. It allows an effective and quick cleaning of a carpet or furniture fabric without deep wetting. It also allows cleaning work to be repeated frequently without damaging the treated carpet on upholstery fabric.

Complete drying takes place very quickly, generally within 20 to 30 minutes. Immediately after applying the The product can be walked over the carpet without the risk of damaging it or counteracting the effect of the product. This drying takes place very quickly, since the powdery composition according to the invention does not in any way moisten the substrate, which always takes a very long time to dry when cleaning is carried out with various conventional products, and also the fibers to be cleaned are only slightly moistened.

Indeed, the cleaning compositions according to the invention set only the amount of solvent left on the fiber as it is necessary to remove the dirt.

Another advantage of using an inventive Composition can be seen in the fact that there is no danger. To form borders or to make the colors matt, as with the compositions very often in the form of solutions or foams

030025/0653

happens. Furthermore, the dust and the pollution after the peeling off from the fiber during the treatment immediately from the powdery one Carriers soaked up, and there is no risk of them flying away or settling again and ultimately a dull and cloudy Leave appearance on the carpet. In addition, the cleaning agent according to the invention can advantageously be more sensitive for cleaning Use textile fabrics without damaging them in any way.

Furthermore, the compositions according to the invention are oil-soluble Stains that are the most common and the most stubborn and caused by essentially aqueous foam cleaners only to one very small part can be removed, very easy to disappear.

After treatment with a composition according to the invention the carpet gets a permanently clean and fluffy appearance. It has dirt-repellent properties similar to those of a new one Carpets are comparable; this is not the case with carpets made with aqueous foam cleaners and especially those that contain surfactants included, were treated.

Indeed, an important feature of the compositions according to the invention is that they preferably contain one or more contain detergent or surface-active agents that do not leave any charged or sticky residue on the fiber after cleaning leave behind.

In addition, the use of the compositions according to the invention particularly useful as it does not require any special equipment. It is suitable for all types of vegetable, animal or synthetic fibers such as wool, cotton, jute, silk, regenerated cellulose, acetate rayon, polyamide, polyester, Polyolefin and polyvinylidene chloride fibers, polyacrylic fibers as well Mixtures of such fibers, and for all types of dyeing of these fibers.
