Description

Durch die in der letzten Zeit ständig zunehmende Verwendung automatischer Wäschetrockner in gewerblichen Wäschereien und privaten Haushalten ergibt sich die Mölichkeit, eine wäschenachbehandlung gleichzeitig mit dem Trocknen im Wäschetrockner vorzunehmen. Es sind deshalb eine Reihe von Vorschlägen gemacht worden, wie verschiedenartige Wirkstoffe, vor allem solche zum Weich- und Antistatischmachen sowie zur Parfümierung von Wäsche auf die Wäsche appliziert werden können.The use of automatic tumble dryers in commercial laundries and private households, which has been increasing steadily in recent times, makes it possible to carry out post-laundry treatment simultaneously with drying in the tumble dryer. A number of proposals have therefore been made as to how different types of active ingredients, especially those for softening and antistatic and for perfuming laundry, can be applied to the laundry.

In den 60er Jahren wurde in den USA ein Verfahren zur Wäschenachbehandlung beschrieben, bei dem man mit üblichen Wirkstoffen imprägnierte flexible Substrate, zum Beispiel mit quartären Ammoniumverbindungen beladene, saugfähige Papierbahnen, wie sie als Papierhandtücher üblich waren, zusammen mit der noch feuchten Wäsche in die Trommel eines automatischen Wäschetrockners gibt und dann den Trocknungsvorgang ablaufen läßt; hierbei werden die Wirkstoffe auf die Wäsche übertragen. Nach der Lehre der DE-AS 19 65 470 führt nicht jedes, mit textilweichmachenden Wirkstoffen beladene flexible Trägermaterial zu guten Resultaten; geeignete Substrate müssen vielmehr eine bestimmte, in einem zahlenmäßig begrenzten Bereich liegende Adsorptionskapazität aufweisen. Substrate, deren Adsorptionsfähigkeit unterhalb dieses Bereichs liegt, setzen nach der Lehre dieser DE-AS die üblichen Wirkstoffe zu schnell frei, so daß die Wirkstoffe ungleichmäßig auf die Wäsche übertragen werden und die behandelte Wäsche fleckig wird. Andererseits soll bei einer Adsorptionsfähigkeit die oberhalb des geforderten Bereichs liegt, zu wenig Wirkstoff von dem Substrat an die Wäsche abgeben werden. Als geeignete Substrate werden in dieser Patentanmeldung bestimmte saugfähige Papiere, Schwämme und gewobene Tücher oder Vliese bezeichnet. Es sind auch spezielle Weichmacher und Weichmacher-Kombinationen bekannt, die mit flexiblen Substraten, an die hinsichtlich ihrer Adsorptionskapazität keine ebenso begrenzten Anforderungen wie in der DE-AS 19 65 470 gestellt werden, kombinierbar sind. Zum Beispiel wird in der DE-OS 27 00 512 ein Gemisch aus einem üblichen kationischen Gewebeweichmacher und einem Fettsäureester eines mehrwertigen Alkohols in einem bestimmten Mischungsverhältnis beschrieben. Aus der DE-OS 27 00 560 ist ein Mittel bekannt, das einen Fettalkylpolyglycerinester als Textilweichmacher enthält. Weitere Literaturstellen über Wäschenachbehandlungsmittel, die im wesentlichen aus Substraten mit einer praktisch unbegrenzten Adsorptionskapazität und speziellen Weichmachern bestehen, sind die Deutschen Offenlegungsschriften Nr. 25 46 505, 26 25 774, 25 16 104, 26 36 787, 25 56 248, 25 37 402 und die US-Patentschriften Nr. 4,073,996, 4,049,858, 4,096,071, 4,142,978, 4,110,498.In the 1960s, a process for post-washing treatment was described in the USA, in which flexible substrates impregnated with conventional active substances, for example absorbent paper webs loaded with quaternary ammonium compounds, as were customary as paper towels, were put into the drum together with the still wet laundry an automatic dryer and then let the drying process run; the active ingredients are transferred to the laundry. According to the teaching of DE-AS 19 65 470, not every flexible carrier material loaded with textile-softening active ingredients leads to good results; rather, suitable substrates must have a certain adsorption capacity which is in a limited number range. According to the teaching of this DE-AS, substrates with an adsorption capacity below this range release the usual active substances too quickly, so that the active substances are transferred unevenly to the laundry and the treated laundry becomes stained. On the other hand, with an adsorption capacity which is above the required range, too little active ingredient is released from the substrate into the laundry. In this patent application, suitable absorbent papers, sponges and woven cloths or nonwovens are designated as suitable substrates. There are also known special plasticizers and plasticizer combinations which can be combined with flexible substrates, to which the adsorption capacity does not impose any equally limited requirements as in DE-AS 19 65 470. For example, DE-OS 27 00 512 describes a mixture of a conventional cationic fabric softener and a fatty acid ester of a polyhydric alcohol in a certain mixing ratio. From DE-OS 27 00 560 an agent is known which contains a fatty alkyl polyglycerol ester as a fabric softener. Further references on laundry aftertreatment agents, which essentially consist of substrates with a practically unlimited adsorption capacity and special plasticizers, are German Offenlegungsschriften No. 25 46 505, 26 25 774, 25 16 104, 26 36 787, 25 56 248, 25 37 402 and U.S. Patent Nos. 4,073,996, 4,049,858, 4,096,071, 4,142,978, 4,110,498.

In der älteren nicht veröffentlichten Europäischen Patentanmeldung 33134, Anmelde-Nr. 81 100 442.3 sind Wäschenachbehandlungen beschrieben, die aus Substraten mit sehr niedriger Adsorptionskapazität bestehen, welche mit einem Überzug aus üblichen textilweichmachenden Verbindungen versehen sind. Bei diesen üblichen textilweichmachenden Verbindungen handelt es sich um in großem Umfang eingesetzte quartäre, von Ammoniak oder Imidazolin abgeleitete Ammoniumverbindungen, die bis zu 80 Gew.-% durch Kondensationsprodukte aus einem Fettsäuretriglycerid und Hydroxyalkylpolyamin ersetzt sein können. Die Mittel der genannten Europäischen Patentanmeldung führen bei ihrer Anwendung im Wäschetrockner bei guter Weichmachungsleistung nicht zur Fleckenbildung auf der Wäsche, obwohl dies nach der Lehre der DE-AS 19 65 470 hätte der Fall sein müssen. Es wurde nun gefunden, daß das Mittel zum Nachbehandeln gewaschener Wäsche in einem Wäschetrockner, bestehend aus einem flexiblen textilen Flächengebilde, welches eine Adsorptionskapazität von 1,0 bis 4,5 und eine gewebe-, vlies- oder schaumstoffartige Struktur aus Polyester, Polyamid, Polyolefin, Polyacrylnitril, Polyurethan oder Viskose und deren Mischungen untereinander, aufweist und mit einem Überzug aus einem weich- und antistatisch machenden Wirkstoff oder Wirkstoffgemisch aus quartären, von Ammoniak oder Imidazolin abgeleiteten Ammoniumverbindungen, die bis zu 80 Gew.-% durch Kondensationsprodukte aus einem Fettsäuretriglycerid und Hydroxyalkylpolyamin ersetzt sein können, versehen ist, wobei der Überzug 0,2 bis 5 Gew.-% aliphatische niedermolekulare Hydroxycarbonsäuren und ggf. 0,05 bis 1 Gew.-% optische Aufheller, jeweils bezogen auf die Menge an weich-und antistatischmachenden Wirkstoffen, sowie ggf. Hilfs-und Duftstoffe enthält, besonders wertvolle Eigenschaften aufweist. Vliesartig struktierte Flächengebilde sind im Rahmen der vorliegenden Erfindung bevorzugt. Sie werden in an sich bekannter Weise durch Luft-, Wasserabscheidung oder mechanisch hergestellt, indem man auf eine gewünschte Länge zurechtgeschnittene thermoplastische oder nichtthermoplastische Fasern für die Vliesbildung vorzugsweise wirr abgelegt und diese durch ein Bindemittel oder durch Temperatureinwirkung (im Fall der Verwendung thermoplastischer Fasern) miteinander verklebt. Man unterscheidet so bindemittelgebundene und schmelzfasergebundene Vliese. Die Art der Herstellung sowie Typ, Menge und Lage der Fasern und deren Verbindung miteinander bestimmen die Eigenschaften der geeigneten Vliese; diese sind aber für ihre Eignung als flexible Substrate in den erfindungsgemäßen Mitteln nicht kritisch, soweit sie eine Adsorptionskapazität von 1,0 bis 4,5 aufweisen. Geeignete Vliese weisen eine Größe von 0,01 bis 0,2 m2 und ein Flächengewicht zwischen etwa 10 und 100 g pro m2 auf. Die Adsorptionskapazität wird gemessen nach einem modifizierten Test (U.S. Federal Specifications UU- T - 595 b) mit Ände:- rungen, wie sie in der DE-AS 19 65 470 beschrieben und im Beisoielteil der Europäischen Patentanmeldung Nr. 33 134 näher erläutert sind. Ein bevorzugtes Fasermaterial für die geeigneten Vliesstoffe besteht aus den thermoplastischen Polymeren Polyolefin, Polyester, Polyamid, Polyacrylnitril. Aus der Reihe geeigneter Vliesstoffe zeichnen sich die folgenden Vliesstoffe besonders aus: Vliesstoffe aus bindemittelgebundenen thermoplastischen Fasern, insbesondere aus Polyester, ferner aus bindemittel-und/oder schutzfasergebundenen Viskosefasern und/oder thermoplastischen Fasern, wovon Vliesstoffe, die aus Gemischen von bindemittelgebundenen thermoplastischen Fasern und Viskose bestehen, bevorzugt sind; ebenfalls besonders gut geeignet und daher bevorzugt sind bindemittelgebundene Vliesstofffe aus Viskosefasern. Ein für die erfindungsgemäßen Mittel ausgezeichnet geeignetes handelsübliches Vlies besteht zum Beispiel aus Polyester-fasern. Es hat ein Flächengewicht von zirka 25 bis 50 g pro m2 und eine Adsorptionskapazität von 2 - 4. Ein anderes Beispiel für ein geeignetes Vlies ist ein Viskose-Fasern hergestelltes Vlies. Es hat ein Flächengewicht von zirka 55 g pro m 2 und eine Adsorptionskapazität von zirka 3,5. Geeignete Vliesstoffe aus einem Fasergemisch sind beispielsweise aus 40 % Polyester und 60 % Viskose hergestellt; sie weisen ein Flächengewicht von zirka 25 bis zirka 35 g pro m2 und eine Adsorptionskapazität von zirka 3,5 auf. Ein ebenfalls geeigneter Vliesstoff besteht aus Polypropylen-Fasern. Er hat ein Flächengewicht von zirka 50 g Dro m2 und eine Adsorntionskapazität von zirka 2,0. Ein anderes Vlies aus Polypropylen-Fasern hat ein Flächengewicht von zirka 35 g pro m2 und eine Adsorptionskapazität von 2,8. Ähnliche Ergebnisse wie mit Mitteln auf Basis von Vliesen erhält man auch mit einem Polyacrylnitrilfaser-Gewebe, das eine Adsorptionskanazität von 1,7 aufweist. Andere geeignete Substrate sind Polyurethan-Schaumstoffe mit einer Adsorptionskapazität von 3,7 bis 4,2. Auch Schaumstoff-Flächengebilde aus Polyethylen und Polypropylen sind geeignete Substrate.In the older unpublished European patent application 33134, application no. 81 100 442.3 describes post-wash treatments which consist of substrates with very low adsorption capacity, which are provided with a coating of conventional textile-softening compounds. These customary textile-softening compounds are quaternary ammonium compounds derived from ammonia or imidazoline, which can be used up to 80% by weight by condensation products of a fatty acid triglyceride and hydroxyalkyl polyamine. The means of the aforementioned European patent application do not lead to staining on the laundry when used in the tumble dryer with good softening performance, although according to the teaching of DE-AS 19 65 470 this should have been the case. It has now been found that the agent for the aftertreatment of washed laundry in a tumble dryer, consisting of a flexible textile fabric which has an adsorption capacity of 1.0 to 4.5 and a fabric, fleece or foam-like structure made of polyester, polyamide, polyolefin , Polyacrylonitrile, polyurethane or viscose and their mixtures with one another, and with a coating of a softening and antistatic agent or agent mixture of quaternary ammonium compounds derived from ammonia or imidazoline, which up to 80 wt .-% by condensation products of a fatty acid triglyceride and Hydroxyalkylpolyamine can be replaced, is provided, wherein the coating 0.2 to 5 wt .-% aliphatic low molecular weight hydroxycarboxylic acids and optionally 0.05 to 1 wt .-% optical brighteners, each based on the amount of softening and antistatic agents, and optionally contains auxiliaries and fragrances, has particularly valuable properties. Nonwoven structured fabrics are preferred in the context of the present invention. They are produced in a manner known per se by air, water separation or mechanically, by laying thermoplastic or non-thermoplastic fibers cut to a desired length, preferably in a confused manner, for the formation of nonwovens, and these by a binder or by the action of temperature (if thermoplastic fibers are used) with one another glued. A distinction is made between binder-bound and melt fiber-bonded nonwovens. The type of manufacture as well as the type, quantity and position of the fibers and their connection with one another determine the properties of the suitable nonwovens; but these are for their suitability as flexible substrates in the agents according to the invention is not critical insofar as they have an adsorption capacity of 1.0 to 4.5. Suitable nonwovens have a size of 0.01 to 0.2 m 2 and a basis weight between about 10 and 100 g per m 2 . The adsorption capacity is measured according to a modified test (US Federal Specifications UU-T - 595 b) with changes, as described in DE-AS 19 65 470 and explained in more detail in the example part of European Patent Application No. 33 134. A preferred fiber material for the suitable nonwovens consists of the thermoplastic polymers polyolefin, polyester, polyamide, polyacrylonitrile. The following nonwovens are particularly distinguished from the series of suitable nonwovens: nonwovens made from binder-bound thermoplastic fibers, in particular from polyester, furthermore from binder-bound and / or protective fiber-bound viscose fibers and / or thermoplastic fibers, of which nonwovens made from mixtures of binder-bound thermoplastic fibers and viscose exist, are preferred; Also particularly suitable and therefore preferred are binder-bound nonwovens made from viscose fibers. A commercially available fleece which is excellently suitable for the agents according to the invention consists, for example, of polyester fibers. It has a weight per unit area of approximately 25 to 50 g per m 2 and an adsorption capacity of 2-4. Another example of a suitable nonwoven is a nonwoven made of viscose fibers. It has a basis weight of approximately 55 g pr om 2 and an adsorption capacity of approximately 3.5. Suitable nonwovens made from a fiber mixture are made, for example, from 40% polyester and 60% viscose; they have a basis weight of approximately 25 to approximately 35 g per m 2 and an adsorption capacity of approximately 3.5. Another suitable nonwoven consists of polypropylene fibers. He has a Basis weight of approximately 50 g D ro m 2 and an adsorption capacity of approximately 2.0. Another nonwoven made of polypropylene fibers has a weight per unit area of approximately 35 g per m 2 and an adsorption capacity of 2.8. Results similar to those obtained with nonwovens are also obtained with a polyacrylonitrile fiber fabric which has an adsorption capacity of 1.7. Other suitable substrates are polyurethane foams with an adsorption capacity of 3.7 to 4.2. Foam sheets made of polyethylene and polypropylene are also suitable substrates.

Als quartäre Ammoniumverbindungen eignen sich vor allem solche mit zwei langkettigen, vorzugsweise gesättigten aliphatischen Resten mit je 14 bis 26, insbesondere im wesentlichen 16 bis 20 Kohlenstoffatomen und wenigstens einem quartären Stickstoffatom im Molekül. Die langkettigen aliphatischen Reste können geradkettig oder verzweigt sein und dementsprechend von Fettsäuren, beziehungsweise von Fettaminen, Guerbetaminen oder aus den durch Reduktion von Nitroparaffinen erhältlichen Alkylaminen abstammen. Bei diesen quartären Ammoniumverbindungen handelt es sich insbesondere um Derivate des Ammoniaks, das heißt um die durch Alkylierung von langkettigen sekundären Aminen erhältlichen quartären Salze, wie zum Beispiel die Verbindungen Distearyldimethylammoniumchlorid beziehungsweise Ditalgalkyldinethylammoniumchlorid oder -methosulfat. Andere geeignete quartäre Ammoniumverbindungen sind die durch Umsetzung von 1 Mol eines Aminoalkylethylendiamins oder Hydroxyalkylethylendiamins mit 2 Mol einer langkettigen C12-C26 -Fettsäure oder deren Ester erhältlichen Imidazolinverbindungen, die anschließend durch Alkylierung in die quartären Imidazoliniumverbindungen übergeführt werden. In allen diesen quartären Ammoniumverbindungen besteht das Anion im allgemeinen aus dem Säurerest, der aus dem bei der Quaternierung verwendeten Alkylierungsmittel entstanden ist. 3eispielsweise kommt als Anion daher Chlorid, Bromid, Methylsulfat, Ethylsulfat, Methan-, Ethan- oder Toluolsulfonat in Betracht. Die quartären Ammoniumverbindungen sind gleichzeitig gute Antistatika. Ein Teil der quartären Ammoniumverbindungen kann durch andere Verbindungen ersetzt werden, zum Beispiel durch die ebenfalls als Textilweichmacher bekannten Kondensationsprodukte aus 1 bis 3 Mol Fettsäure oder Fettsäurealkylester und 1/3 bis 1 Mol Fettsäuretriglycerid mit einem Mol eines Hydroxyalkylpolyamins, beispielsweise Hydroxvethylethylendiamin Hydroxyethyldiethylentriamin. Besonders geeignet ist das durch Umsetzung von 1 Mol eines Fettsäuretriglycerids, insbesondere gehärtetem Talg, mit 1 Mol Hydroxyethylethylendiamin bei 90 bis 150 °C erhältliche Produkt. Vorzugsweise wird als Textilweichmacher eine quartäre Ammoniumverbindung des Ammoniaktyps mit zwei im wesentlichen C16 -C20-Alkyl- oder Alkenylgruppen und zwei Methylgruppen im Molekül und mit dem Chlorid-, Bromid- oder Methylsulfat-Anion, insbesondere Ditalgalkyldimethylammoniumchlorid, allein oder in Kombiantion mit dem Fettsäurekondensationsprodukt aus 1 Mol gehärtetem Talg und 1 Mol Hydroxyethylethylendiamins im Verhältnis 4 : 1 bis 1 : 4 eingesetzt. Diese Kombinationen führen bei den behandelten Textilien zu einer gleichmäßigen markanten Griffverbesserung ohne Fleckenbildung.Suitable quaternary ammonium compounds are especially those with two long-chain, preferably saturated aliphatic radicals each having 14 to 26, in particular essentially 16 to 20, carbon atoms and at least one quaternary nitrogen atom in the molecule. The long-chain aliphatic radicals can be straight-chain or branched and can accordingly be derived from fatty acids or from fatty amines, Guerbetamines or from the alkylamines obtainable by reduction of nitroparaffins. These quaternary ammonium compounds are, in particular, derivatives of ammonia, that is to say the quaternary salts obtainable by alkylation of long-chain secondary amines, such as, for example, the compounds distearyldimethylammonium chloride or ditalgalkyldinethylammonium chloride or methosulfate. Other suitable quaternary ammonium compounds are the imidazoline compounds obtainable by reacting 1 mol of an aminoalkylethylenediamine or hydroxyalkylethylenediamine with 2 mol of a long-chain C 12 -C 26 fatty acid or its ester, which are subsequently converted into the quaternary imidazolinium compounds by alkylation. In all of these quaternary ammonium compounds, the anion generally consists of the acid residue, which consists of that in the Quaternization used alkylating agent has arisen. For example, chloride, bromide, methyl sulfate, ethyl sulfate, methane, ethane or toluenesulfonate are suitable as anions. The quaternary ammonium compounds are also good antistatic agents. Some of the quaternary ammonium compounds can be replaced by other compounds, for example by the condensation products, also known as textile softeners, of 1 to 3 moles of fatty acid or fatty acid alkyl ester and 1/3 to 1 mole of fatty acid triglyceride with one mole of a hydroxyalkylpolyamine, for example hydroxvethylethylenediamine, hydroxyethyldiethylenetriamine. The product obtained by reacting 1 mol of a fatty acid triglyceride, in particular hardened tallow, with 1 mol of hydroxyethylethylenediamine at 90 to 150 ° C. is particularly suitable. A quaternary ammonium compound of the ammonia type with two essentially C 16 -C 20 -alkyl or alkenyl groups and two methyl groups in the molecule and with the chloride, bromide or methyl sulfate anion, in particular ditallow alkyldimethylammonium chloride, alone or in combination with the is preferably used as textile softener Fatty acid condensation product from 1 mol hardened tallow and 1 mol hydroxyethylethylenediamine in a ratio of 4: 1 to 1: 4. These combinations lead to a uniform, striking improvement in the treated textiles without staining.

Geeignete niedermolekulare Hydroxycarbonsäuren enthalten 1 oder 2 Hydroxygruppen und 1 bis 3 Carboxylgruppen und weisen ein Molekulargewicht bis zirka 250 auf. Insbesondere handelt es sich um Säuren aus der Gruppe umfassend die Verbindungen Apfelsäure, Weinsäure, Tartronsäure, Milchsäure, Glykolsäure, Citronensäure und deren Mischungen wovon die Milchsäure, die Glykolsäure und besonders die Citronensäure und deren Mischungen bevorzugt sind..Suitable low molecular weight hydroxycarboxylic acids contain 1 or 2 hydroxy groups and 1 to 3 carboxyl groups and have a molecular weight of up to about 250. In particular, these are acids from the group comprising the Compounds malic acid, tartaric acid, tartronic acid, lactic acid, glycolic acid, citric acid and mixtures thereof, of which lactic acid, glycolic acid and especially citric acid and mixtures thereof are preferred.

Als optische Aufheller werden insbesondere Aufheller für Baumwolle eingesetzt. Hierbei handelt es sich vor allem um De.rivate der Diaminostilbendisulfonsäure beziehungsweise deren Alkalimetallsalze.In particular, brighteners for cotton are used as optical brighteners. These are primarily derivatives of diaminostilbenedisulfonic acid or its alkali metal salts.

Zweckmäßigerweise enthalten die Mittel in der Überzugsmasse 0,2 bis 5 Gew.-% der oben genannten Hydroxycarbonsäuren oder Phosphonsäuren sowie gegebenenfalls 0,05 bis 1 Gew.-% optische Aufheller, jeweils bezogen auf die Menge an weich- und antistatischmachendem Wirkstoff.The agents expediently contain 0.2 to 5% by weight of the abovementioned hydroxycarboxylic acids or phosphonic acids and, if appropriate, 0.05 to 1% by weight of optical brighteners, in each case based on the amount of softening and antistatic active ingredient.

Als Hilfsmittel kommen vor allem nichtionische Disperga- toren in Betracht. Zusätzlich können auch Antimikrobika; Soil-release-Substanzen, Bügelhilfen und Imprägniermittel vorhanden sein.As an aid, especially non-ionic Dis come p erga factors into consideration. In addition, antimicrobials; Soil-release substances, ironing aids and impregnating agents are available.

Als nichtionische Dispergatoren eignen sich in erster Linie Anlagerungsprodukte von 4 bis 40, vorzugsweise von 4 bis 20 Mol Ethylenoxid an 1 Mol eines aliphatischen C1-C20-Alkohols beziehungsweise eines Alkylphenols, in welchen der Alkylrest 8 bis 18 Kohlenstoffatome aufweist, sowie Fettsäuren und Alkylamine mit 10 bis 20 Kohlenstoffatomen. Besonders bevorzugt sind die Ethoxylierungsprodukte der Fettalkohole, insbesondere der Kokos- und Talgfettalkohole und des Oleyalkohols sowie die Ethoxylierungsprodukte der Oxoalkohole und sekundären Alkohole der entsprechenden Kettenlängen. Weitere geeignete nichtionische Tenside sind. die wasserlöslichen 20 bis 250 Ethylenglykolethergruppen und 10 bis 100 ProDylenglykol- ethergruppen enthaltenden Anlagerungsprodukte von Ethylenoxid an Polyaropylenglykol beziehungsweise an Alkylendiaminuolypropylenglykol beziehungsweise an Alkylpolypropylenglykole mit 1 bis 10 C-Atomen, in denen die Polypropylenglykolkette als hydrophober Rest fungiert. Alle diese Verbindungen bewirken in Mengenanteilen von etwa 5 bis etwa 60 Gew.-% der Beschichtung eine gleichmäßige Verteilung der Wirk- und Duftstoffe bei der Herstellung und Anwendung der erfindungsgemäßen Mittel. Als antimikrobielle Wirkstoffe, das heißt bakterizid oder bakteriostatisch beziehungsweise fungizid oder fungistatisch wirkende Verbindungen kennen ebenfalls quartäre Ammoniunverbindungen, insbesondere solche, die neben einem langkettigen alipha-_ tischen und zwei kurzkettigen aliphatischen Kohlenwasserstoffresten einen aromatischen, über ein aliphatisches Kohlenwasserstoffatom mit dem Stickstoffatom verknüDften oder einen aliphatischen, Doppelverbindungen aufweisenden organischen Rest im Molekül enthalten, vorhanden sein. Typische Vertreter für derartige antimikrobielle Wirkstoffe sind die Verbindungen Dimethylbenzylhexyl-allyldodecylam- moniumchlorid.Brauchbare antimikrobielle Wirkstoffe sind auch die Bromnitroalkohole wie zum Beispiel die Verbindungen 2-Brom-2-nitropropan-1,3-diol, 1-Brom-1-nitro-3,3-trichlor-2-propanol, 2-Brom-2-nitrobutanol.Suitable nonionic dispersants are primarily addition products of 4 to 40, preferably 4 to 20, moles of ethylene oxide to 1 mole of an aliphatic C 1 -C 20 alcohol or an alkylphenol, in which the alkyl radical has 8 to 18 carbon atoms, and fatty acids and alkylamines with 10 to 20 carbon atoms. The ethoxylation products of the fatty alcohols, in particular the coconut and tallow fatty alcohols and the oley alcohol, and the ethoxylation products of the oxo alcohols and secondary alcohols of the corresponding chain lengths are particularly preferred. Other suitable nonionic surfactants are. the water-soluble 20 to 250 ethylene glycol ether groups and 10 to 100 Pro D ylenglykol- ether groups containing adducts of ethylene oxide with Polyaropylenglykol or at Alkylendiaminuolypropylenglykol or at Alkylpolypropylenglykole having 1 to 10 C atoms, in which the polypropylene glycol chain acts as a hydrophobic radical. All of these compounds, in proportions of about 5 to about 60% by weight of the coating, bring about an even distribution of the active ingredients and fragrances in the preparation and use of the agents according to the invention. Quaternary ammonium compounds are also known as antimicrobial active substances, that is to say bactericidal or bacteriostatic or fungicidal or fungistatic compounds, in particular those which, in addition to a long-chain aliphatic and two short-chain aliphatic hydrocarbon radicals, associate an aromatic one or an aliphatic hydrocarbon atom with the nitrogen atom or an aliphatic one Organic compound containing double compounds in the molecule may be present. Typical representatives of such antimicrobial agents are the compounds dimethylbenzylhexyl-allyldodecylammonium chloride. Usable antimicrobial agents are also the bromo nitro alcohols such as the compounds 2-bromo-2-nitropropane-1,3-diol, 1-bromo-1-nitro-3,3-trichloro-2-propanol, 2-bromo-2-nitrobutanol.

Als Wirkstoffe zur Soil-release-Ausrüstung für Textilien eignen sich Verbindungen, die das Schmutzablösevermögen während der Wäsche verbessern. Dazu gehören Verbindungen vom Typ der Polyacrylpolyvinylalkohole, der modifizierten Fluorkohlenwasserstoffe und hydrophile Polymere. Polyvinylacetate, Paraffine, aber auch Borax eignen sich als Zusätze, die das Bügeln der Wäsche erleichtern. Die Herstellung der erfindungsgemäßen Mittel erfolgt, indem man ein Stück des Substrats mit dem Gemisch aus textilweichmachendem Wirkstoff, niedermolekularer Hydroxycarbonsäure, dem gegebenenfalls optischer Aufheller und/oder Hilfs- und Duftstoffe zugesetzt wurden, in einer solchen Menge imprägniert, daß das Substrat die für die Behandlung eines Wäschepostens im automatischen Wäschetrockner ausreichende Wirkstoff-Imprägnierung aufweist. Dies sind bei einem Haushaltswäschetrockner mit 4 bis 5 k3 (Trockengewicht) Fassungsvermögen zirka 0,5 bis zirka 10 g, wobei im allgemeinen eine Menge von 1 bis 5 g, die bei erstmaligem Gebrauch eines solchen Mittels auf dem Substrat vorhanden sind, ausreicht. Eine derartige Menge Wirkstoff wird von dem für die erfindungsgemäßen Mittel geeigneten Substrat mit einer Größe von etwa 0,01 bis 0,2 m2 aufgenommen; eine für den praktischen Gebrauch vorteilhafte Größe liegt zwischen 0,02 und 0,07 m2. Für die Anwendung in gewerblichen Betrieben nimmt man größere Stücke entsprechend dem größeren Fassungsvermögen der dort verwendeten Geräte. Hiervon kann der Verwender jeweils eine oder, wenn eine stärkere Wirkung verlangt wird, auch zwei oder mehrere Stücke zusammen mit der Wäsche in den Wäschetrockner geben. Statt eines Stückes des Substrats dieser Größe imprägniert man zur Herstellung der erfindungsgemäßen Mittel zweckmäßigerweise ein großes Stück oder eine zusammenhängende Bahn des Substrats und zerteilt dieses dann später in Stücke der gewünschten Größe. Die Imprägnierung des Substrats kann man auf verschiedene Weise vornehmen. Geeignete Methoden sind beispielsweise beidseitiges Bedrucken, Aufwalzen, Aufrakeln, Besprühen oder vorzugsweise Tauchen des Substrats in eine Lösung, Dispersion oder vorzugsweise in eine Schmelze der Wirk-, Duft- und gegebenenfalls Hilfsstoffe und anschließendes Trocknen und/oder Abkühlen, beispielsweise mittels Luft oder indirekt durch Kontaktsysteme. Zur Vermeidung von Verlusten an flüchtigen Stoffen, zum Beispiel Duftstoffen, ist darauf zu achten, daß man die Temperatur einer Schmelze nicht unnötig lange unnötig hoch einstellt. Eine Temperatur bis höchstens 90 °C reicht gewöhnlich aus, wobei im allgemeinen eine Temperatur von nicht mehr als zirka 60 °C sich beim Aufschmelzen handelsüblicher quartärer Ammoniumverbindungen als günstig herausgestellt hat. Die Auftragsmenge kann man entweder durch dosierte Beschichtung oder durch Tränken des Substrats und anschließendes Abquetschen des Überschusses durch einen Walzenspalt vornehmen.Compounds which improve the dirt-removing ability during washing are suitable as active ingredients for soil release finishing for textiles. These include compounds of the polyacrylic polyvinyl alcohol type, modified fluorocarbons and hydrophilic polymers. Polyvinyl acetates, paraffins, but also borax are suitable additives that make ironing the laundry easier. The agents according to the invention are produced by impregnating a piece of the substrate with the mixture of textile-softening active ingredient, low molecular weight hydroxycarboxylic acid, to which optical brighteners and / or auxiliaries and fragrances have been added, in such an amount that the substrate is used for the treatment a laundry item in the automatic tumble dryer has sufficient active ingredient impregnation. In the case of a household clothes dryer with a 4 to 5 k 3 (dry weight) capacity, these are approximately 0.5 to approximately 10 g, an amount of 1 to 5 g which is generally present on the substrate when such an agent is used for the first time is sufficient. Such an amount of active ingredient is from the substrate suitable for the agents according to the invention with a size of about 0.01 to 0.2 m 2 added; a size which is advantageous for practical use is between 0.02 and 0.07 m 2 . For use in commercial companies, larger pieces are taken according to the larger capacity of the devices used there. Of these, the user can put one or, if a stronger effect is required, two or more pieces together with the laundry in the tumble dryer. Instead of impregnating a piece of the substrate of this size, a large piece or a coherent web of the substrate is expediently impregnated to produce the compositions according to the invention and this is then later divided into pieces of the desired size. The substrate can be impregnated in various ways. Suitable methods are, for example, double-sided printing, rolling on, knife coating, spraying or, preferably, immersing the substrate in a solution, dispersion or, preferably, in a melt of the active ingredients, fragrances and, if appropriate, auxiliaries and subsequent drying and / or cooling, for example by means of air or indirectly by Contact systems. In order to avoid losses of volatile substances, for example fragrances, it is important to ensure that the temperature of a melt is not set unnecessarily high for an unnecessarily long time. A temperature up to a maximum of 90 ° C. is usually sufficient, although a temperature of not more than approximately 60 ° C. has generally been found to be favorable when commercial quaternary ammonium compounds are melted. The application quantity can be carried out either by metered coating or by soaking the substrate and then squeezing off the excess through a nip.

Geeignete Lösungsmittel für Lösungen und Dispersionen der üblichen Wirkstoffe sind zum Beispiel die niederen aliphatischen Alkohole Methylalkohol, Ethylalkohol oder Isopropylalkohol, die gegebenenfalls mit Wasser vermischt sind. Die Lösungen können ebenso wie die Dispersionen und Schmelzen Hilfsstoffe, insbesondere Dispergiermittel enthalten.Suitable solvents for solutions and dispersions of the Typical active ingredients are, for example, the lower aliphatic alcohols methyl alcohol, ethyl alcohol or isopropyl alcohol, which are optionally mixed with water. Like the dispersions and melts, the solutions can contain auxiliaries, in particular dispersants.

Die Form der Stücke ist beliebig, man kann kreisförmige, ovale, eckige, geometrische oder nicht geometrische Formen verwenden. Im allgemeinen werden viereckige Formen und eine Bahnrolle, die beisDielsweise eine Perforation zwischen den für eine Wäschetrockner-Füllung benötigten Stücken aufweist, bevorzugt.The shape of the pieces is arbitrary, you can use circular, oval, angular, geometric or non-geometric shapes. In general, square shapes and a roll of web having, for example, a perforation between the pieces required for a tumble dryer filling are preferred.

Behandelt man feuchte Wäsche im Wäschetrockner mit einem erfindungsgemäßen Mittel, indem man das Mittel während des Trocknugsvorgangs auf die Wäsche einwirken läßt, so weist die Wäsche nach der Behandlung einen angenehmen weichen Griff und die gewünschte Duftnote auf; die Wäsche weist zudem keinerlei von ungleichmäßiger Wirkstoffübertragung herrührende Flecken auf. Die erfindungsgemäßen Mittel sind längere Zeit ohne Vergilbung lagerfähig; der Duft der parfümierten Mittel ist sauber und reintönig.If wet laundry is treated in the tumble dryer with an agent according to the invention by allowing the agent to act on the laundry during the drying process, the laundry has a pleasantly soft feel and the desired fragrance after the treatment; the laundry also has no stains due to uneven transfer of active ingredient. The agents according to the invention can be stored for a long time without yellowing; the scent of the perfumed means is clean and pure.

Ein Polyesterfaservlies mit einem Flächengewicht von zirka 40 g pro m 2 und einer Adsorptionskapazität von 2,8 wurde in ein homogenes Gemisch aus pastenförmigem Ditalgalkyldimethylammoniumchlorid (75 %ig), dem 1 Gew.-% Citronensäure und 3 Gew.-% einer 10 %igen Lösung von 4,4'-Bis-(2-sülfostyrol-)biphenyl (optischer Aufheller für Baumwolle) und geringe Mengen Duftstoffe zugesetzt waren, eingetaucht. Das Vlies hatte nach dem Abkühlen und Trocknen zirka 90 g pro m2 an Überzugsmasse aufgenommen. Nach zirka 2- bis 3-wöchiger Lagerung bei 40 °C wurde festgestellt, daß das so hergestellte Mittel eine merklich verringerte Vergilbungstendenz im Vergleich zu Mitteln aufwiesen, die ohne Citronensäure und optischen Aufheller in der Überzugsmasse hergestellt waren. Der Duft des erfindungsgemäßen Mittels wurde vor und nach der Lagerung von in der Duftbeurteilung erfahrenen Testpersonen als "abgerundeter" und "sauberer" beurteilt als der Duft der Vergleichs-Mittel. In ähnlicher Weise wurde der Duft der mit dem erfindungsgemäßen Mittel behandelten Wäsche als vorteilhafter beurteilt.A polyester fiber fleece with a weight per unit area of approximately 40 g per m 2 and an adsorption capacity of 2.8 was mixed into a homogeneous mixture of paste-like ditallow alkyldimethylammonium chloride (75%), 1% by weight of citric acid and 3% by weight of a 10% Solution of 4,4'-bis (2-sülfostyrol-) biphenyl (optical brightener for cotton) and small amounts of fragrances were added, immersed. After cooling and drying, the fleece had absorbed about 90 g per m 2 of coating mass. After approximately 2 to 3 weeks of storage at 40 ° C., it was found that the agent thus produced had a markedly reduced tendency to yellowing in comparison with agents which were produced in the coating composition without citric acid and optical brighteners. Before and after storage, test persons experienced in the fragrance assessment rated the scent of the composition according to the invention as "rounded" and "cleaner" than the scent of the comparison compositions. In a similar manner, the scent of the laundry treated with the agent according to the invention was judged to be more advantageous.
