Abstract
Description
Die vorliegende Erfindung betrifft ein streufähiges Mittel zur Trockenreinigung von Textilien, insbesondere von Teppichen.The present invention relates to a scatterable agent for dry cleaning of textiles, especially carpets.
Zur Reinigung von Teppichen und anderen textilen Belägen an Ort und Stelle verwendet man neben Shampoos in neuerer Zeit zunehmend pulverförmige Reinigungsmittel, die den Vorteil aufweisen, keine Ränder zu hinterlassen und schneller abzutrocknen. Derartige Reinigungspulver bestehen im wesentlichen aus größeren Mengen an Adsorbtionsmitteln und einer daran adsorbierten Reinigungsflüssigkeit, die meist überwiegend aus Wasser besteht. Von der Reinigungsflüssigkeit wird angenommen, daß sie für die Ablösung der Schmutzteilchen von den Fasern und für deren Transport zum Adsorbtionsmittel sorgt, das dann nach dem Abtrocknen zusammen mit dem Schmutz gebürstet oder abgesaugt wird. Als Adsorbtionsmittel sind die verschiedensten Materialien vorgeschlagen worden, von denen hier nur die in der europäischen Patentanmeldung 178 566 beschriebenen Cellulosepulver, die in jüngerer Zeit besondere Bedeutung erlangt haben, erwähnt werden sollen. Obwohl mit Reinigungsmitteln auf Basis von Cellulosepulver bereits ein recht hoher Standard hinsichtlich Reinigungsleistung und Vergrauungsinhibierung erreicht worden war, wurde trotzdem weiter nach neuen Zusammensetzungen gesucht, die eine noch höhere Reinigungsleistung und eine geringere Wiederanschmutzung aufweisen und die in noch geringerem Maße zur Aufrauhung der Teppichoberfläche und zur Akkumulation von Reinigungsmittelrückständen auf den Teppichen bei Mehrfachanwendung führen.For cleaning carpets and other textile coverings on the spot In addition to shampoos, powdered cleaning agents have been used more and more recently, which have the advantage of not leaving any margins and dry faster. Such cleaning powders essentially exist from larger amounts of adsorbents and one adsorbed thereon Cleaning liquid, which mostly consists of water. From the cleaning liquid is assumed to be used for the detachment of the Dirt particles from the fibers and for their transport to the adsorbent that then brushed together with the dirt after drying or is suctioned off. A wide variety of materials are used as adsorbents have been proposed, of which only those in European Patent application 178 566 cellulose powder described in more recent Time have acquired special meaning, should be mentioned. Although with Detergents based on cellulose powder are already quite high Standard achieved in terms of cleaning performance and graying inhibition was still looking for new compositions, which have an even higher cleaning performance and less re-soiling have and to a lesser extent to roughen the Carpet surface and for the accumulation of detergent residues lead the carpets with multiple use.
In der US-Patentschrift 3 630 919 ist auch schon der Vorschlag gemacht worden, pulverförmigen Teppichreinigungsmitteln kolloidale Kieselsäure in geringen Mengen zuzusetzen. Trotz gewisser Verbesserungen, die auf diese Weise erreicht wurden, befriedigen auch die in der US-Patentschrift beschriebenen Reinigungsmittel nicht. The proposal has already been made in US Pat. No. 3,630,919 been powdered carpet cleaners in colloidal silica add small amounts. Despite some improvements on this Ways of being achieved also satisfy those described in the U.S. patent Detergent not.
Überraschenderweise wurde jetzt festgestellt, daß streufähige Teppichreinigungsmittel, die sowohl Cellulosepulver als auch kolloidale Kieselsäure enthalten, eine in vielfacher Hinsicht bessere Wirksamkeit aufweisen als die bisher bekannten Mittel.Surprisingly, it has now been found that scatterable carpet cleaning agents, which are both cellulose powder and colloidal silica contain, in many ways have better efficacy than the previously known means.
Gegenstand der vorliegenden Patentanmeldung ist daher ein streufähiges Trockenreinigungsmittel für Textilien, das Cellulospulver, kolloidales Siliciumdioxid und Wasser enthält. Vorzugsweise enthält das Mittel darüber hinaus zusätzlich geringe Mengen an Tensid und/oder rollfähige Partikel aus porösem, elastischem Material.The subject of the present patent application is therefore a scatterable Dry cleaning agent for textiles, cellulose powder, colloidal Contains silicon dioxide and water. Preferably, the agent contains above in addition, small amounts of surfactant and / or rollable particles made of porous, elastic material.
Das neue Reinigungsmittel weist eine außerordentlich hohe Reinigungsleistung auf und zeichnet sich durch eine sehr geringe Wiederanschmutzneigung der damit gereinigten Textilien aus. Im Vergleich zu herkömmlichen Mitteln ist außerdem die Neigung zur Akkumulation von Rückständen bei mehrfacher Anwendung auf dem selben Textilmaterial deutlich geringer. Besonders überraschend ist aber die ungewöhnliche Schonung der Textilmaterialien während des Reinigungsvorganges. Eine gute Reinigungswirkung wird mit streufähigen Teppichreinigungsmitteln im allgemeinen nur dann erreicht, wenn sie nach dem Aufstreuen mit Hilfe von Bürsten entweder manuell oder maschinell in den Teppich eingearbeitet werden, damit sie möglichst mit allen schmutztragenden Fasern in Berührung kommen. Das Einbürsten des Reinigungspulvers stellt wegen der übertragenden Kräfte besondere Anforderungen an die Festigkeit der Teppichfasern. Eine Aufrauhung der Oberfläche und der Verlust von Teppichfasern lassen sich oft nicht vermeiden und können bei mehrfacher Anwendung zur sichtbaren Beschädigung des textilen Materials führen. Diese bei allen herkömmlichen Mitteln in mehr oder minder starkem Maße feststellbare Schädigung des Textilmaterials tritt bei Anwendung der erfindungsgemäßen Mittel in sehr viel geringerem Umfang auf.The new cleaning agent has an exceptionally high cleaning performance and is characterized by a very low tendency to re-soiling of the textiles cleaned with it. Compared to conventional means is also the tendency to accumulate residues in multiple Use on the same textile material significantly less. Particularly surprising but is the unusual protection of the textile materials during of the cleaning process. A good cleaning effect is with scatterable Carpet cleaners are generally only achieved if they are after sprinkling with the help of brushes either manually or mechanically the carpet can be worked in so that it is as possible with all dirt-bearing Fibers come into contact. Brushing in the cleaning powder places special demands on strength due to the transmitted forces the carpet fibers. Surface roughening and loss Of carpet fibers can often not be avoided and can with multiple Use lead to visible damage to the textile material. This with all conventional means to a greater or lesser extent detectable damage to the textile material occurs when using the invention Funds on a much smaller scale.
Die für die erfindungsgemäßen Mittel geeigneten Cellulosepulver werden aus
handelsüblicher Cellulose, die in der Regel aus Pflanzenteilen, insbesondere
aus Holz, gewonnen wird, durch Zerkleinern mit Hilfe von mechanischen
und/oder chemischen Prozessen hergestellt. Derartige Pulver, die farblos
und nahezu frei von Lignin und anderen aus dem Pflanzenmaterial stammenden
Verunreinigungen sind, werden in unterschiedlicher Feinheit vom Handel
angeboten. Für die Zwecke der vorliegenden Erfindung eignen sich vorzugsweise
die feineren Qualitäten, die eine mittlere Faserlänge im Bereich von
50 bis 400 Mikrometern aufweist. Bei diesen Qualitäten liegt die durchschnittliche
Faserdicke meist zwischen 10 und 50 Mikrometern. Die Bestimmung
der Teilchengröße des Cellulosepulvers kann auch über Siebverfahren
vorgenommen werden, so beispielsweise mit Hilfe der Luftstrahlsiebung nach
DIN 53734. Bevorzugt werden deshalb auch Cellulosepulver, die in ihren
Siebkennzahlen (nach dem vorgenannten Verfahren) folgende Korngrößenverteilung
aufweist:
Vorzugsweise werden in den erfindungsgemäßen Mitteln Cellulosepulver verwendet, die aus Holzcellulose, insbesondere aus Laubholzcellulose hergestellt wurden. Eine besonders bevorzugte Cellulosetype ist Buchenholzcellulose. Von diesen Pulvertypen werden wiederum jene Qualitäten besonders bevorzugt, die in technisch einfacher Weise allein auf mechanischem Wege, d.h. durch Vermahlen, hergestellt werden. Der Anteil des Cellulosepulvers im erfindungsgemäßen Mittel beträgt vorzugsweise 36 bis 55 Gew.-%, insbesondere 39 bis 52 Gew.-%, bezogen auf das fertige Mittel.Cellulose powder is preferably used in the agents according to the invention, those made from wood cellulose, especially hardwood cellulose were. A particularly preferred cellulose type is beech wood cellulose. Of these powder types, those qualities are special preferred, which is done in a technically simple manner solely by mechanical means, i.e. by grinding. The proportion of cellulose powder in the agent according to the invention is preferably 36 to 55% by weight, in particular 39 to 52 wt .-%, based on the finished agent.
Als zweiten wesentlichen Wirkstoff enthalten die erfindungsgemäßen Mittel kolloidales Siliciumdioxid, auch als kolloidale Kieselsäure bezeichnet. Dieses Material wird vom Handel als kolloidale wäßrige Lösung mit verschiedenen Konzentrationen angeboten, wobei die Kieselsäureteilchen meist durch kationische oder anionische Oberflächenladung in der Lösung stabilisiert sind. Die Lösungen können zur Stabilisierung weitere anorganische Materialien, insbesondere Alkali und lösliche Salze enthalten. Beispiele für geeignete Handelsprodukte sind die Typen Ludox(R) und Syton(R) der Firma Du Pont und Levasil(R) der Firma Bayer. Die Lösungen enthalten die Kieselsäure in Form von meist kugelförmigen Einzelpartikeln, die an der Oberfläche hydroxiliert sind, und deren Größe in der Mehrzahl der Fälle zwischen etwa 7 und etwa 50 Nanometern liegt. Wenn die kolloidalen Kieselsäurelösungen für sich allein eintrocknen, ergeben sich je nach Partikelgröße Feststoffe mit spezifischen Oberflächen (BET-Methode) zwischen 100 und 300 m2/g. Für die Herstellung der erfindungsgemäßen Mittel werden die kolloidalen Kieselsäuren aber dem Cellulosepulver und den sonstigen Bestandteilen vorzugsweise in Form ihrer kolloidalen Lösung zugesetzt. Besonders bevorzugt werden solche kolloidalen Kieselsäuren, deren einzelne Teilchen durch anionischen Oberflächenladungen stabilisiert sind, und die insbesondere Natriumionen als Gegenionen enthalten. Die Menge an kolloidal gelöstem Siliciumdioxid beträgt in den erfindungsgemäßen Mitteln vorzugsweise 0,1 bis 10 Gew.-%, insbesondere 1,5 bis 5 Gew.-%, gerechnet als wasserfreie Aktivsubstanz und bezogen auf die vollständigen erfindungsgemäßen Mittel.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 being mostly stabilized in the solution by cationic or anionic surface charge. For stabilization, the solutions can contain further inorganic materials, in particular alkali and soluble salts. Examples of suitable commercial products are the types Ludox (R) and Syton (R) from Du Pont and Levasil (R) 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. If the colloidal silica solutions dry on their own, depending on the particle size, solids with specific surfaces (BET method) between 100 and 300 m 2 / g result. For the preparation of the agents according to the invention, 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 an anhydrous active substance and based on the complete agents according to the invention.
Zusätzlich zu Cellulosepulver und kolloidalen Siliciumdioxid können die erfindungsgemäßen Mittel auch weitere pulverförmige Adsorbentien, wie sie an sich für derartige Trockenreinigungsmittel bekannt sind, enthalten, wenn das zur Erreichung besonderer zusätzlicher Effekte wünschenswert ist. Beispiele solcher Adsorbentien sind Bentonit, Kieselgur, Zeolith, Stärke und Kunststoffschaumpulver, wie etwa gemahlener Polyurethanschaum. Als zusätzliches Adsorptionsmittel, das gleichzeitig als Volumengeber fungiert, hat sich gemahlenes Schaumglas (Perlit) bewährt. Die Menge dieser zusätzlichen Adsorptionsmittel wird in jedem Falle so gewählt, daß die Eigenschaften der Mittel nicht nachteilig verändert werden. Ihr Gehalt liegt deshalb in den erfindungsgemäßen Mitteln stets unter dem Gehalt an Cellulosepulver, vorzugsweise beträgt er weniger als 50 Gew.-%, insbesondere weniger als 30 Gew.-%, bezogen auf den Gehalt an Cellulosepulver. In addition to cellulose powder and colloidal silica, the Agents according to the invention also other powdered adsorbents, such as them are known per se for such dry cleaning agents, if this is desirable to achieve special additional effects. Examples of such adsorbents are bentonite, diatomaceous earth, zeolite and starch and plastic foam powder, such as ground polyurethane foam. As additional adsorbent, which also acts as a volume generator, ground foam glass (perlite) has proven itself. The amount of this additional adsorbent is chosen in any case so that the Properties of the funds can not be changed adversely. Your salary is therefore always below the content of the agents according to the invention Cellulose powder, preferably it is less than 50% by weight, in particular less than 30 wt .-%, based on the content of cellulose powder.
Neben den vorgenannten Adsorbentien enthalten die erfindungsgemäßen Mittel im einfachsten Falle lediglich Wasser als Tränkflüssigkeit.

Der Gehalt an Wasser, der sich aus der bei der Herstellung zugesetzten Wassermenge und dem in den Rohstoffen schon enthaltenen Wasser ergibt, beträgt vorzugsweise 35 bis 70, insbesondere 40 bis 60 Gewichtsprozent.In addition to the aforementioned adsorbents, the agents according to the invention contain in the simplest case, only water as an impregnating liquid. The amount of this Liquid is measured so that it is still from the solid components the means, d. that is, especially from cellulose powder and thus the spreadability of the funds is guaranteed. 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, especially 40 to 60 percent by weight.

For example, the liquid contain organic solvents. Suitable as organic solvents both water-miscible and water-immiscible solvents, as far as they do not attack the textiles and are sufficiently volatile are in order after applying the agent to the textiles in the desired Time to evaporate. Furthermore, the choice of solvents to ensure that they are sufficiently high in the finished product mixture Have flash points and are toxicologically safe. Well suited are 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 of these solvents. Monoalcohols with 2 to 3 carbon atoms and their are preferred Mixtures used.

The anionic surfactants are preferably used in the form of the sodium salts, however, the lithium salts can also offer advantages.
Besonders geeignete Tenside vom Sulfattyp sind die Schwefelsäuremonoester von langkettigen primären Aloholen natürlichen und synthetischen Ursprungs mit 10 bis 20 C-Atomen, d. h. von Fettalkoholen, wie z. B. Kokosfettalkoholen, Talgfettalkoholen, Oleylalkohol oder den C10-C20-Oxoalkoholen und solche von sekundären Alkoholen dieser Kettenlängen. Daneben kommen die Schwefelsäuremonoester der mit 1 bis 6 Mol Ethylenoxid ethoxylierten aliphatischen primären Alkohole, sekundären Alkohole oder Alkylphenole in Betracht. Diese Tenside werden auch als Ethersulfate bezeichnet. Ferner eignen sich sulfatierte Fettsäurealkanolamide und sulfatierte Fettsäuremonoglyceride.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.

These surfactants are also known as ether sulfates. Sulfated fatty acid alkanolamides and sulfated fatty acid monoglycerides are also suitable.
Bei den Tensiden vom Sulfonattyp handelt es sich in erster Linie um Sulfobernsteinsäuremono- und -diester mit 6 bis 22 C-Atomen in den Alkoholteilen, um die Alkylbenzolsulfonate mit C9-C15-Alkylgruppen und um die Ester von Alpha-Sulfofettsäuren, z. B. die alpha-sulfonierten Methyl- oder Ethylester der hydrierten Kokos-, Palmkern- oder Talgfettsäuren. Gut geeignet sind ebenfalls die Alkansulfonate, die aus C12-C18-Alkanen durch Sulfochlorierung oder Sulfoxidation und anschließende Hydrolyse bzw. Neutralisation oder durch Bisulfidaddition an Olefine erhältlich sind, sowie die Olefinsulfonate, das sind Gemische aus Alken- und Hydroxyalkansulfonaten sowie Disulfonaten, wie man sie beispielsweise aus langkettigen Monoolefinen mit end- oder innenständiger Doppelbindung durch Sulfonieren mit gasförmigem Schwefeltrioxid und anschließender alkalischer oder saurer Hydrolyse der Sulfonierungsprodukte erhält.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 9 -C 15 -alkyl groups and the esters of alpha-sulfofatty acids, e.g. B. the alpha-sulfonated methyl or ethyl esters of hydrogenated coconut, palm kernel or tallow fatty acids.

Neben den bereits genannten Bestandteilen können die Mittel dieser Erfindung noch andere in Textil- und Teppichreinigungsmitteln übliche Hilfs- und Zusatzstoffe in geringer Menge enthalten. Beispiele solcher Wirkstoffe sind antistatisch wirkende Komponenten, optischer Aufheller, die Wiederanschmutzung vermindernde Stoffe, die Streubarkeit und Verteilbarkeit verbessernde Zusätze, Konservierungsmittel und Parfüm. Vor allem dann, wenn stark staubende Komponenten in die Mittel eingearbeitet werden sollen, ist es zweckmäßig, zur Staubbindung auch kleine Mengen an Wachsen oder Ölen zuzusetzen. Üblicherweise werden von diesen Hilfs- und Zusatzstoffen insgesamt nicht mehr als 5 Gew.-% verwendet; vorzugsweise liegt der Gehalt nicht über 2 Gew.-%, bezogen auf das gesamte Mittel.In addition to the components already mentioned, the agents of this invention can other auxiliary materials common in textile and carpet cleaning agents and additives in a small amount. Examples of such agents are antistatic components, optical brighteners, re-soiling reducing substances, improving spreadability and spreadability Additives, preservatives and perfume. Especially if heavily dusting components to be incorporated into the agent it is advisable to use small amounts of waxes or oils to bind dust to add. Usually, of these auxiliaries and additives as a whole not more than 5% by weight used; preferably the content is not more than 2% by weight, based on the total agent.
Als ein besonders bevorzugtes Hilfsmittel sind in den erfindungsgemäßen Reinigungsmitteln größere rollfähige Partikel aus porösem elastischem Material anzusehen, die insbesondere aus Schwamm-Material bestehen. Diese Partikel haben eine längste Abmessung zwischen etwa 1 und 50, vorzugsweise zwischen etwa 1 und 10 mm, wobei die Abmessungen in den beiden anderen Raumrichtungen, die zueinander und auf dieser Länge senkrecht stehen, wenigstens 10 %, insbesondere wenigstens 20 % dieser größten Länge ausmachen. Bei diesen rollfähigen Partikeln kann es sich um regelmäßig oder unregelmäßig geformte Körper handeln. Entscheidend ist, daß die Form so gestaltet ist, daß die Körper beim Einarbeiten des Teppichreinigungsmittels unter der über den Teppich geführten Bürste rollen können. Als Formen kommen demnach Kugeln, Zylinder, Ellipsoide, Eiformen, aber auch unregelmäßig geformte Körper, wie sie beispielsweise durch Agglomeration von kleineren Teilchen zu Granulaten entstehen, in Frage. Insbesondere bei sehr elastischen und leicht verformbaren Materialien können aber auch stärker eckige Körper bis hin zu Würfeln und Quadern durchaus rollfähig und für die erfindungsgemäßen Mittel geeignet sein.As a particularly preferred auxiliary are in the invention Detergents larger rollable particles made of porous elastic material to look at, which consist in particular of sponge material. This Particles have a longest dimension between about 1 and 50, preferably between about 1 and 10 mm, the dimensions in the other two Spatial directions that are perpendicular to each other and along this length, at least 10%, in particular at least 20% of this greatest length. These rollable particles can be regular or act irregularly shaped bodies. It is crucial that the form is so is designed that the body when incorporating the carpet cleaning agent can roll under the brush passed over the carpet. As forms come spheres, cylinders, ellipsoids, egg shapes, but also irregular shaped bodies, as for example by agglomeration of smaller particles to form granules, in question. Especially at very elastic and easily deformable materials can also more angular bodies up to cubes and cuboids can be rolled and be suitable for the agents according to the invention.
Die rollfähigen Partikel können aus verschiedensten Materialien bestehen. Besonders bevorzugt werden aber rollfähige Partikel, die überwiegend bis vollständig aus Viskose, Naturschwamm oder offenporigem Kunststoffschaum bestehen. Zur Herstellung der rollfähigen Partikel geht man vorzugsweise von größeren Materialstücken aus, die durch Zerschneiden oder Vermahlen auf die gewünschte Größe zerkleinert werden. Vorzugsweise wird geschäumtes Material, Vliesstoff oder Gewebe, als Ausgangsmaterial verwendet. In einer besonders bevorzugten Ausführungsform bestehen die rollfähigen Partikel aus Viskoseschwammflocken. The rollable particles can consist of different materials. Rollable particles that predominantly up to completely made of viscose, natural sponge or open-pored plastic foam consist. It is preferable to produce the rollable particles from larger pieces of material that are cut or ground be crushed to the desired size. Foamed is preferred Material, nonwoven or fabric, used as the starting material. In a The rollable particles are particularly preferred from viscose sponge flakes.
Die rollfähigen Teilchen verbinden sich während des Reinigungsvorganges mit Flusen und Fasern, die sich auf den Teppichen abgelagert haben und können dann zusammen mit diesen leicht von der Teppichoberfläche entfernt werden. Der Gehalt an rollfähigen Teilchen kann in den erfindungsgemäßen Mitteln verhältnismäßig klein sein, da bereits wenige Partikel ausreichen, um den gewünschten Effekt zu erzielen. So beträgt der Anteil der rollfähigen Partikel in den Mitteln vorzugsweise etwa 0,1 bis 10 Gew.-%, insbesondere 0,1 bis 1 Gew.-%, bezogen auf das gesamte Mittel.The rollable particles combine during the cleaning process with fluff and fibers that have deposited on the carpets and can then be easily removed from the carpet surface along with these will. The content of rollable particles can in the invention Be relatively small, since only a few particles are sufficient, to achieve the desired effect. So the share of rollable is Particles in the agents preferably about 0.1 to 10 wt .-%, in particular 0.1 to 1 wt .-%, based on the total agent.
Die Herstellung der Mittel bietet keine Probleme, so daß technisch einfache, meist einstufige Verfahren angewandt werden können. Üblicherweise werden einfache Mischapparaturen, wie Schaufel- oder Trommelmischer eingesetzt, in denen Cellulosepulver und gegebenenfalls weitere feste Komponenten vorgelegt und dann unter Bewegung mit den Flüssigkeiten, die gegebenenfalls weitere Bestandteile gelöst enthalten, bedüst werden. Je nach Mechanik und Zusammensetzung können auf diese Weise die Mittel in sehr feinteiliger oder auch in mehr oder weniger agglomerierter Form hergestellt werden, doch wird durch die Zusammensetzung stets gewährleistet, daß auch die agglomerierten Formen auf den Textilien ohne größeren mechanischen Aufwand leicht zerfallen. Durch die Wahl flockiger Agglomerate kann die Rieselfähigkeit der Mittel gedämpft werden bis hin zu stark zögernd fließenden Produkten, wie sie für bestimmte Anwendungszwecke bevorzugt werden.The preparation of the agents presents no problems, so that technically simple, mostly one-step processes can be used. Usually simple mixing devices such as paddle or drum mixers are used, in which cellulose powder and possibly other solid components submitted and then moving with the liquids, if necessary contain other components dissolved, sprayed. Depending on Mechanics and composition can be used in this way finely divided or in more or less agglomerated form but the composition always ensures that even the agglomerated forms on the textiles without major mechanical Effort disintegrate easily. By choosing flaky agglomerates the flowability of the agents can be dampened up to very hesitant flowing products, as preferred for certain applications will.
Auch das Schüttgewicht der Mittel läßt sich im Herstellprozeß durch die Wahl mehr oder weniger kompakter Agglomerate in gewissem Umfang beeinflussen. So weisen die Mittel üblicherweise Schüttgewichte im Bereich von 200 bis 350 g/l auf, mit der Folge, daß verhältnismäßig große Volumina pro Flächeneinheit angewendet werden. Dies erleichtert insbesondere dann, wenn die Mittel von Hand auf Teppiche aufgestreut werden, eine gleichmäßige Verteilung. The bulk density of the agents can be in the manufacturing process by To a certain extent influence the choice of more or less compact agglomerates. The agents usually have bulk densities in the range of 200 up to 350 g / l, with the result that relatively large volumes per Area unit can be applied. This makes it easier if the remedies are sprinkled on carpets by hand, an even one Distribution.
Die Reinigung der Textilien und Teppiche geschieht in der Weise, daß die erfindungsgemäßen Reinigungsmittel manuell oder mit Hilfe eines geeigneten Streugerätes auf die Textilien aufgestreut und anschließend mehr oder weniger intensiv in die Textilien, beispielsweise mit Hilfe eines Schwammes oder einer Bürste eingerieben werden. In der Regel wählt man Einarbeitungszeiten von 0,5 bis 2,5 Minuten, vorzugsweise 0,5 bis 1,5 Minuten pro Quadratmeter. Nach dem Einreiben läßt man die Textilien abtrocknen, bis sich die Reinigungsmittel, die sich mit dem Schmutz verbinden, in trockene Rückstände verwandelt haben. Diese Rückstände werden dann auf mechanischem Wege, beispielsweise durch Ausbürsten oder Absaugen aus den Textilien entfernt. Für die Flächenreinigung von Textilien werden von den erfindungsgemäßen Mitteln je nach Fülle der Textilien und je nach Verschmutzungsgrad 2 bis 150 g/m2 angewandt, doch können zur Entfernung einzelner Flecken stellenweise auch größere Mengen aufgetragen werden. Zur Flächenreinigung von Teppichböden sind Aufwandmengen von 10 bis 100 g/m2 üblich. Das gesamte Verfahren kann, etwa im Haushalt, weitgehend manuell durchgeführt werden, doch besteht auch die Möglichkeit, das Einreiben und gegebenenfalls weitere Schritte mit Hilfe von geeigneten Maschinen, beispielsweise kombiniertem Streu- und Bürstmaschinen, auszuführen, so daß sich das Verfahren ebensogut für die Anwendung im gewerblichen Bereich eignet. The cleaning of the textiles and carpets takes place 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 into the textiles more or less intensively, for example with the aid of a sponge or a brush. As a rule, training times of 0.5 to 2.5 minutes, preferably 0.5 to 1.5 minutes per square meter are chosen. 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. For the surface cleaning of textiles, 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 2 are customary for cleaning carpets. The entire process can be carried out largely manually, for example in the household, but there is also the possibility of rubbing in and, if necessary, further steps using suitable machines, for example combined spreading and brushing machines, so that the process is equally suitable for use suitable in the commercial sector.
Die in den folgenden Beispielen beschriebenen Reingungsmittel wurden auf folgende Weise hergestellt:The cleaning agents described in the following examples were based on manufactured in the following way:
In einem Schaufelmischer wurden Cellulosepulver und gegebenenfalls Viskoseflocken vorgelegt und vorgemischt. Getrennt davon wurde die wäßrige Reinigungsflüssigkeit aus den übrigen Komponenten ohne die kolloidale Kieselsäure in einem Mischbehälter hergestellt. Diese Flüssigkeit wurde dann unter weiterem Bewegen des Schaufelmischers auf das Adsorbtionsmittel aufgesprüht, bevor anschließend die Kieselsäurelösung aufgesprüht wurde. Es entstanden in allen Fällen leicht feuchte, aber gut rieselfähige Produkte.Cellulose powder and optionally viscose flakes were placed in a paddle mixer submitted and premixed. The aqueous was separated Cleaning liquid from the other components without the colloidal silica made in a mixing container. This liquid was then sprayed onto the adsorbent while moving the paddle mixer further, before the silica solution was then sprayed on. It in all cases, slightly damp but free-flowing products were created.
Als Cellulosepulver wurde in den nachfolgend beschriebenen Beispielen der
Typ Arbocel (R)B 800 X der Firma J. Rettenmaier & Söhne verwendet, der
nach Herstellerangaben eine durchschnittliche Faserlänge von 200 µm und
eine durchschnittliche Faserdicke von 20 µm und bei der Luftstrahlsiebung
folgende Siebkennzahlen aufweist:
Als kolloidale Kieselsäure wurde in den Beispielen das Produkt Ludox HS 40(R) der Firma Du Pont verwendet. Es handelt sich dabei um eine kolloidale wäßrige Lösung mit 40 Gew.-% SiO2, in der die Kieselsäureteilchen negativ geladen und mit Natriumionen stabilisiert sind.The product Ludox HS 40 (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.
Bei den in einigen Beispielen verwendeten Viskoseflocken handelte es sich um ein Produkt der Firma Beli-Chemie GmbH, das für die Verwendung als Saugflocken zur Aufnahme verschütteter Flüssigkeiten angeboten wird. Das Material weist ein Schüttgewicht von etwa 90 g/l auf. The viscose flakes used in some examples were a product of the company Beli-Chemie GmbH, which can be used as Suction flakes for absorbing spilled liquids is offered. The Material has a bulk density of approximately 90 g / l.
Die Prüfung der Reinigungsleistung wurde an Teppichbodenstücken vorgenommen, die mit künstlicher Anschmutzung versehen waren. Als Teppichmaterial diente ein hellgrauer Polyamidschlingenteppich, der in Stücken der Größe 122,5 x 79 cm in einer Laboranschmutztrommel unter Zusatz von 1500 g Stahlkugeln 30 Minuten lang mit 15 g einer Testanschmutzung der Wäschereiforschungsanstalt Krefeld (bestehend zu 85 Gew.-% aus dem gesiebten Inhalt eines Staubsaugerbeutels und zu 15 Gew.-% aus einem Standardgemisch aus Kaolin, Quarzmehl, Eisenoxid und Ruß) angeschmutzt wurde. Das Teppichstück wurde dann gründliche abgesaugt und für die weiteren Versuche in drei gleich große etwa 40 cm breite Stücke unterteilt.The cleaning performance was checked on pieces of carpet, which were provided with artificial soiling. As carpet material served a light gray polyamide loop carpet that was in pieces of size 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 soil from the laundry research institute Krefeld (consisting of 85% by weight of the screened content a vacuum cleaner bag and 15% by weight from a standard mixture Kaolin, quartz powder, iron oxide and soot). The piece of carpet was then suctioned off thoroughly and for further experiments in three evenly sized pieces about 40 cm wide divided.
Die Reinigungsversuche wurden auf Teilflächen von ca. 0,25 qm auf den angeschmutzten Teppichstücken in der Weise durchgeführt, daß 25 g Reinigungspulver gleichmäßig aufgestreut und dann durch Bürsten in die Fläche eingearbeitet wurden. Als Werkzeug diente eine mittelharte Bürste mit Polypropylenborsten, mit der die Fläche etwa 25 Sekunden lang mit kräftigen Strichen aus verschiedenen Richtungen gleichmäßig bearbeitet wurde. Nach dem Abtrocknen, das etwa 4 Stunden in Anspruch nahm, wurden die Teppichstücke gründlich abgesaugt, bis keine Pulverrückstände mehr auf dem Teppich zu erkennen waren. Die Auswertung erfolgte mit Hilfe des Farbdifferenz-Meßgerätes Micro Color der Firma Dr. Lange unter Anwendung der CIELAB-Methode (DIN 6074). Dabei wird die dreidimensionale Farbdarstellung in Form des L*-, a*-, b*-Diagramms herangezogen, wobei sich die Helligkeit (L*), auch Grauwert genannt, auf der senkrechten Achse des dreidimensionalen Farbkörpers befindet. Der Wert L*0 = 0 ist gleichgesetzt mit schwarz; der Wert L*100 = 100 ist die Helligkeit des Weißstandards, an dessen Stelle bei den hier durchgeführten Messungen der unbehandelte Teppich gesetzt wurde. In den nachfolgenden Tabellen ist als Reinigungsergebnis bei den einzelnen Beispielsrezepturen angegeben, um wieviele Einheiten der Wert L* heller oder dunkler ermittelt wurde als bei Reinigung mit dem als Standard verwendeten Mittel A. The cleaning tests were carried out on partial areas of approximately 0.25 square meters 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 evenly with strong lines from different directions for about 25 seconds. After drying, which took about 4 hours, the carpet pieces were thoroughly vacuumed until no powder residues were visible on the carpet. The evaluation was carried out using 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 *, and b * diagram is used, the brightness (L *), also known as the gray value, being located on the vertical axis of the three-dimensional color body. The value L * 0 = 0 is equated with black; the value L * 100 = 100 is the brightness of the white standard, in the place of which the untreated carpet was placed in the measurements carried out here. In the following tables, 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.
Die Prüfung des Wiederanschmutzverhaltens wurde in der Weise durchgeführt, daß Teppichstücke der Abmessung 40 x 79, die aus dem gleichen Material wie oben angegeben bestanden, zunächst einem Reinigungsvorgang, wie er vorstehend beschrieben wurde, unterworfen wurden und erst dann mit der Testanschmutzung in der obenangegebenen Weise behandelt wurden. Die Auswertung erfolgte hier visuell, jeweils im Vergleich zu Teppichstücken, die mit dem Standardreinigungsmittel behandelt worden waren. Dabei wurde folgende Bewertungsskala verwendet:
- ++ =
- stark erhöhte Wiederanschmutzung gegebenüber dem Standardmittel
- + =
- erhöhte Wiederanschmutzung gegenüber dem Standardmittel
- +- =
- gleiche Wiederanschmutzung wie das Standardmittel
- - =
- verringerte Wiederanschmutzung gegenüber dem Standardmittel
- ++ =
- greatly increased re-soiling given over the standard medium
- + =
- increased re-contamination compared to the standard agent
- + - =
- same re-soiling as the standard agent
- - =
- reduced re-contamination compared to the standard agent
Zur Messung der Faserbeanspruchung beim Einarbeiten des Reinigungspulvers wurde eine Teppichbürste mit harten Polypropylenborsten unter standardisierten Bedingungen über einen gleichmäßig mit Reinigungspulver bestreuten Teppichboden aus Nadelfilz gezogen. Die Menge an Reinigungspulver betrug auch bei diesen Versuchen 100 g pro m2. Die für die gleichförmige Bewegung der Bürste notwendige Zugkraft wurde mit einer Federwaage gemessen und ist in Tabelle 1 in Gramm angegeben. Je geringer diese Kraft ist, um so weniger werden die Teppichfasern bei der Reinigung beansprucht.To measure the fiber stress when the cleaning powder was incorporated, a carpet brush with hard polypropylene bristles was drawn under standardized conditions over a carpet made of needle felt that was evenly sprinkled with cleaning powder. The amount of cleaning powder in these experiments was 100 g per m 2 . The pulling force required for the uniform movement of the brush was measured with a spring balance and is given in grams in Table 1. The lower this force, the less the carpet fibers are used during cleaning.
In den folgenden Tabellen 1 bis 3 ist die Zusammensetzung der einzelnen,
für die Versuche verwendeten Mitteln in Gewichtsprozenten angegeben, wobei
sich die Angaben auf Aktivsubstanz beziehen. Aus den Ergebnissen wird die
ausgezeichnete Wirksamkeit der erfindungsgemäßen Mittel 1 bis 15 deutlich.
