Definitions
- the present invention relates to a scatterable agent for dry cleaning textiles, in particular carpets.
- the subject of the present patent application is therefore a scatterable dry cleaning agent for textiles, which contains cellulose powder, colloidal silicon dioxide and water.
- the agent preferably additionally contains small amounts of surfactant and / or rollable particles made of porous, elastic material.
- the new cleaning agent has an extraordinarily high cleaning performance and is characterized by a very low tendency towards re-soiling of the textiles cleaned therewith. Compared to conventional agents, the tendency to accumulate residues when used multiple times on the same textile material is also significantly lower. However, the unusual protection of the textile materials during the cleaning process is particularly surprising. A good cleaning effect is generally only achieved with scatterable carpet cleaning agents if they are worked into the carpet either manually or mechanically after sprinkling with the aid of brushes, so that they come into contact with all dirt-carrying fibers as far as possible. Brushing in the cleaning powder places special demands on the strength of the carpet fibers because of the transmitted forces.
- the cellulose powders suitable for the agents according to the invention are made from commercially available cellulose, which is generally obtained from parts of plants, in particular from wood, by comminution using mechanical means and / or chemical processes. Such powders, which are colorless and almost free of lignin and other impurities originating from the plant material, are commercially available in various finenesses.
- the finer qualities which have an average fiber length in the range from 50 to 400 micrometers, are preferably suitable. With these qualities, the average fiber thickness is usually between 10 and 50 micrometers.
- the particle size of the cellulose powder can also be determined using a sieving method, for example using air jet sieving in accordance with DIN 53734. Cellulose powder which has the following particle size distribution (according to the aforementioned method) is therefore also preferred:
- Cellulose powders which have been produced from wood cellulose, in particular from hardwood cellulose, are preferably used in the agents according to the invention.
- a particularly preferred cellulose type is beech wood cellulose.
- those qualities are again particularly preferred which, in a technically simple manner, can only be obtained mechanically, i.e. by grinding.
- the proportion of cellulose powder in the composition according to the invention is preferably 36 to 55% by weight, in particular 39 to 52% by weight, based on the finished composition.
- the agents according to the invention contain colloidal silicon dioxide, also referred to as colloidal silica, as the second essential active ingredient.
- This material is commercially available as a colloidal aqueous solution with various concentrations, the silica particles usually being stabilized in the solution by a cationic or anionic surface charge.
- the solutions can be used to stabilize other inorganic Contain materials, especially alkali and soluble salts. Examples of suitable commercial products are the types Ludo ⁇ ( ⁇ ) and Syton (R) from Du Pont and LevasilW from Bayer.
- the solutions contain the silica in the form of mostly spherical individual particles which are hydroxylated on the surface and the size of which is in the majority of cases between about 7 and about 50 nanometers.
- colloidal silica solutions dry on their own, depending on the particle size, solids with specific surfaces (BET method) of between 100 and 300 ⁇ m / g result.
- the colloidal silicas are preferably added to the cellulose powder and the other constituents in the form of their colloidal solution. Those colloidal silicas whose individual particles are stabilized by anionic surface charges and which in particular contain sodium ions as counterions are particularly preferred.
- the amount of colloidally dissolved silicon dioxide in the agents according to the invention is preferably 0.1 to 10% by weight, in particular 1.5 to 5% by weight, calculated as water-free active substance and based on the complete agents according to the invention.
- the agents according to the invention can also contain further powdery adsorbents, as are known per se for such dry cleaning agents, if this is desirable in order to achieve special additional effects.
- adsorbents are bentonite, diatomaceous earth, zeolite, starch and plastic foam powder, such as ground polyurethane foam.
- Ground foam glass (perlite) has proven itself as an additional adsorbent which also functions as a volume generator. The amount of these additional adsorbents is chosen in any case so that the properties of the agents are not adversely affected.
- the agents according to the invention are therefore always below the content of cellulose powder, preferably it is less than 50% by weight, in particular less than 30% by weight, based on the content of cellulose powder.
- the agents according to the invention only contain water as the soaking liquid. The amount of this liquid is dimensioned such that it is still absorbed by the solid constituents of the agents, ie, in particular by the cellulose powder, and thus the scatterability of the agents is ensured.
- the water content which results from the amount of water added during production and the water already contained in the raw materials, is preferably 35 to 70, in particular 40 to 60 percent by weight.
- the impregnating liquid can, however, if this appears appropriate for special reasons, also contain further auxiliaries and additives which are advantageous, for example, for increasing the cleaning effect or for preserving the finished agent.
- the liquid can contain organic solvents. Suitable organic solvents are both water-miscible and water-immiscible solvents, provided they do not attack the textiles and are sufficiently volatile to evaporate in the desired time after the agents have been applied to the textiles. When selecting the solvents, it is also important to ensure that they have sufficiently high flash points in the finished product mixture and are toxicologically harmless.
- Alcohols, ketones, glycol ethers and hydrocarbons, for example isopropanol, acetone, ethers of mono- and diethylene glycol and mono-, di- and tripropylene glycol with boiling points between 120 ° C and petrol with a boiling range of 130 to 200 ° C, as well as mixtures, are particularly suitable from these solvents.
- Monoalcohols with 2 to 3 carbon atoms and mixtures thereof are preferably used.
- the proportion of organic solvents is usually not more than 20% by weight, in particular 2 to 10% by weight, based on the total cleaning agent.
- the agents according to the invention can furthermore contain surfactants as cleaning-active additives, these surfactants preferably originating from the classes of anionic and nonionic surfactants. While excellent surface cleaning can be achieved without the addition of surfactants, the addition of surfactants improves the removal of fatty stains.
- a surfactant addition of up to 10% by weight is sufficient; the compositions preferably contain 0.05 to 5% by weight, in particular 0.1 to 3% by weight, based on the total weight of the composition, of surfactants. From the large number of known surfactants, those substances are particularly suitable which, together with the adsorbents contained and, if appropriate, further nonvolatile constituents of the compositions, dry to a solid, brittle residue.
- Suitable nonionic surfactants for the agents according to the invention are, in particular, addition products of 1 to 30, preferably 4 to 15, moles of ethylene oxide or mixtures of ethylene oxide and propylene oxide with one mole of a compound having 10 to 20 carbon atoms from the group of alcohols, alkylphenols, carboxylic acids and Carboxamides.
- the condensation products from reducing sugars and long-chain alcohols known under the name alkylglycosides are also very suitable.
- Particularly preferred are the addition products of ethylene oxide with long-chain primary or secondary alcohols, such as. B. fatty alcohols or oxo alcohols and the alkyl polyglucosides composed of glucose and fatty alcohols with 1 to 3 glucose units per molecule and 8 to 18 carbon atoms in the alkyl radical.
- Suitable anionic surfactants are in particular those of the sulfate or sulfonate type, but other types such as soaps, long-chain N-acyl sarcosinates, salts of long-chain sulfosuccinic acid esters or salts of ether carboxylic acids, such as those obtainable from long-chain alkyl or alkylphenyl polyglycol ethers and chloroacetic acid, can also be used , be used.
- the anionic surfactants are preferably used in the form of the sodium salts, but the lithium salts can also offer advantages.
- Particularly suitable surfactants of the sulfate type are the sulfuric acid monoesters of long-chain primary alcohols of natural and synthetic origin with 10 to 20 carbon atoms, ie of fatty alcohols, such as, for. B. Coconut fatty alcohol pick lkoholen tallow fatty alcohols, oleyl alcohol or the C ⁇ o-C2 ⁇ -O ⁇ ° a and those of secondary alcohols of these chain lengths.
- the sulfuric acid monoesters of the aliphatic primary alcohols, secondary alcohols or alkylphenols ethoxylated with 1 to 6 mol of ethylene oxide can be considered.
- These surfactants are also known as ether sulfates. Sulfated fatty acid alkanolamides and sulfated fatty acid monoglycerides are also suitable.
- the surfactants of the sulfonate type are primarily sulfosuccinic acid monoesters and diesters with 6 to 22 carbon atoms in the alcohol parts, the alkylbenzenesulfonates with C 1 -C 4 -alkyl groups and the esters of alpha-sulfo fatty acids , e.g. B. the alpha-sulfonated methyl or ethyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.
- alkanesulfonates which are obtainable from C 12 -C 8 -alkanes by sulfochlorination or sulfoxidation and subsequent hydrolysis or neutralization or by bisulfide addition to olefins
- olefinsulfonates which are mixtures of alkene and hydroxyalkanesulfonates as well as disulfonates as obtained, for example, from long-chain monoolefins with a terminal or internal double bond by sulfonation with gaseous sulfur trioxide and subsequent alkaline or acidic hydrolysis of the sulfonation products.
- Particularly preferred surfactants are the olefin sulfonates, which are preferably used in the formulations in amounts of 0.1 to 1% by weight, but in particular the fatty alcohol sulfates and fatty alcohol ether sulfates, which are preferably used in amounts of between 0.1 and 5% by weight. -% are used.
- the agents of this invention can also contain small amounts of other auxiliaries and additives customary in textile and carpet cleaning agents.
- active ingredients are components with an antistatic effect, optical brighteners, substances which reduce reuse, additives which improve spreadability and spreadability, preservatives and perfume.
- waxes or oils it is advisable to add small amounts of waxes or oils to bind dust.
- no more than 5% by weight of these auxiliaries and additives are used; the content is preferably not more than 2% by weight, based on the total composition.
- rollable particles made of porous elastic material which consist in particular of sponge material, are to be regarded as a particularly preferred auxiliary in the cleaning agents according to the invention.
- These particles have a longest dimension of between approximately 1 and 50, preferably between approximately 1 and 10 mm, the dimensions in the two other spatial directions, which are perpendicular to one another and along this length, at least 10%, in particular at least 20%, of these largest Make out length.
- These rollable particles can be regularly or irregularly shaped bodies. It is crucial that the shape is designed so that when the carpet cleaning agent is incorporated, the bodies can roll under the brush guided over the carpet.
- spheres, cylinders, ellipsoids, egg shapes, but also irregularly shaped bodies, such as are formed, for example, by agglomeration of smaller particles into granules, are suitable as shapes.
- irregularly shaped bodies such as are formed, for example, by agglomeration of smaller particles into granules, are suitable as shapes.
- angular bodies including cubes and cuboids, may well be able to roll and be suitable for the agents according to the invention.
- the rollable particles can consist of different materials. Rollable particles which consist predominantly to completely of viscose, natural sponge or open-pore plastic foam are particularly preferred. Larger pieces of material are preferably used to produce the rollable particles, which are cut to the desired size by cutting or grinding. Foamed material, nonwoven fabric or fabric is preferably used as the starting material. In a particularly preferred embodiment, the rollable particles consist of viscose sponge flakes. During the cleaning process, the rollable particles combine with fluff and fibers that have deposited on the carpets and can then be easily removed from the carpet surface together with them.
- the content of rollable particles in the agents according to the invention can be relatively small, since only a few particles are sufficient to achieve the desired effect.
- the proportion of rollable particles in the compositions is preferably about 0.1 to 10% by weight, in particular 0.1 to 1% by weight, based on the total composition.
- the preparation of the agents presents no problems, so that technically simple, mostly one-step processes can be used.
- Simple mixing apparatuses such as paddle or drum mixers, are usually used, in which cellulose powder and, if appropriate, further solid components are introduced and then sprayed with the liquids which, if appropriate, contain dissolved further constituents.
- the agents can be produced in very fine-particle form or in more or less agglomerated form, but the composition always ensures that the agglomerated forms on the textiles can easily be made without major mechanical effort disintegrate.
- the free-flowing properties of the agents can be dampened down to products which flow very slowly, as are preferred for certain applications.
- the bulk density of the agents can also be influenced to a certain extent in the manufacturing process by the choice of more or less compact agglomerates. So the agents usually have bulk weights in the range of 200 to 350 g / 1, with the result that relatively large volumes are used per unit area. This makes it easier to distribute the product evenly, especially when sprinkled on carpets by hand.
- the textiles and carpets are cleaned in such a way that the cleaning agents according to the invention are sprinkled onto the textiles manually or with the aid of a suitable scattering device and then rubbed more or less intensively into the textiles, for example with the aid of a sponge or a brush.
- training times of 0.5 to 2.5 minutes, preferably 0.5 to 1.5 minutes per square meter are chosen.
- the textiles After rubbing in, the textiles are allowed to dry until the cleaning agents that combine with the dirt have turned into dry residues. These residues are then removed from the textiles mechanically, for example by brushing or vacuuming.
- 2 to 150 g / m 2 are used by the agents according to the invention, depending on the fullness of the textiles and depending on the degree of soiling, but larger amounts can also be applied in places to remove individual stains.
- Application rates of 10 to 100 g / m ⁇ are customary for cleaning carpets.
- the entire method can be carried out largely manually, for example in the household, but there is also the possibility of rubbing in and, if appropriate, further steps using suitable machines, for example combined spreading and brushing machines, so that the Ver ⁇ driving is also suitable for use in the commercial sector.
- aqueous cleaning liquid was prepared from the other components in a mixing container without the colloidal silica. This liquid was then sprayed onto the adsorbent while the paddle mixer was moved further, before the silica solution was subsequently sprayed on. In all cases, slightly moist, but free-flowing products were produced.
- the cellulose powder used was the Arbocel ( R ) ß 800 X from J. Rettenmaier & Söhne, which according to the manufacturer's information has an average fiber length of 200 ⁇ m and an average fiber thickness of 20 ⁇ m and the following sieving characteristics for air jet sieving:
- Ludox HS 4 ⁇ (R) from Du Pont was used as colloidal silica in the examples. It is a colloidal aqueous solution with 40% by weight SiO 2, in which the silica particles are negatively charged and stabilized with sodium ions.
- the viscose flakes used in some examples were a product from Beli-Chemie GmbH and are offered for use as suction flakes for absorbing spilled liquids.
- the material has a bulk density of about 90 g / 1.
- the cleaning performance was checked on pieces of carpet which were provided with artificial soiling.
- a light gray polyamide loop carpet was used as the carpet material, which in pieces measuring 122.5 x 79 cm in a laboratory dirt drum with the addition of 1500 g steel balls for 30 minutes with 15 g of test soiling from the Krefeld laundry research institute (consisting of 85% by weight of the sieved contents of a vacuum cleaner bag and 15 wt .-% from a standard mixture of kaolin, quartz powder, iron oxide and soot).
- the piece of carpet was then thoroughly suctioned off and divided into three equally large pieces of approximately 40 cm in width for the further experiments.
- the cleaning tests were carried out on subareas of approximately 0.25 m 2 on the soiled carpet pieces in such a way that 25 g of cleaning powder were sprinkled uniformly and then worked into the area by brushing.
- a medium-hard brush with polypropylene bristles was used as the tool, with which the surface was worked uniformly with strong strokes from different directions for about 25 seconds.
- the evaluation was carried out with the aid of the Micro Color color difference measuring device from Dr. Long using the CIELAB method (DIN 6074).
- the three-dimensional color representation in the form of the L *, a *, b * diagram is used, the brightness (L *), also called the gray value, being located on the vertical axis of the three-dimensional color body.
- the cleaning result for the individual example formulations is indicated by how many units the value L * was determined lighter or darker than when cleaning with agent A used as standard.
- the test of the re-soiling behavior was carried out in such a way that pieces of carpet measuring 40 ⁇ 79, which consisted of the same material as specified above, were first subjected to a cleaning process, as described above, and only then with the test soiling were treated in the manner indicated above. The evaluation was carried out visually, in each case in comparison to pieces of carpet that had been treated with the standard cleaning agent. The following evaluation scale was used:
- Tables 1 to 3 below show the composition of the individual agents used for the experiments in percentages by weight, the information relating to active substance. The excellent effectiveness of agents 1 to 15 according to the invention is evident from the results. Table 1
