Description

Die Erfindung betrifft ein insbesondere als Bügelhilfe dienendes Wäschenachbehandlungsmittel.The invention relates to a laundry aftertreatment agent serving in particular as an ironing aid.

Es ist bekannt, als Bügelhilfe für Wäsche, insbesondere aus Baumwolle, eine wässerige Dispersion aus einem wasserunlöslichen Gleitmittel, insbesondere einem Siliconöl, und einem wasserlöslichen Filmbildner, insbesondere einem wasserlöslichen Stärkederivat, zu verwenden. Diese Dispersion wird auf die zu bügelnde Wäsche aufgesprüht und ermöglicht ein gegenüber einer nicht behandelten Wäsche leichteres Gleiten des Bügeleisens, wobei der Filmbildner der gebügelten Wäsche eine gewisse Steifigkeit verleiht, die insbesondere bei Hemden und Blusen erwünscht ist.It is known to use an aqueous dispersion of a water-insoluble lubricant, in particular a silicone oil, and a water-soluble film former, in particular a water-soluble starch derivative, as an ironing aid for laundry, in particular of cotton. This dispersion is sprayed onto the laundry to be ironed and enables the iron to slide more easily than an untreated laundry, the film former imparting a certain stiffness to the ironed laundry, which is particularly desirable for shirts and blouses.

Das Einsprühen der Wäsche mittels einer Spraydose ist jedoch kostspielig und daher vorwiegend nur auf die Anwendung bei Hemden und Blusen beschränkt. Darüber hinaus ist der mit der vorstehend beschriebenen bekannten Dispersion erzielte Gleiteffekt noch nicht ganz befriedigend. Ferner ist es schwierig, das Gewebe gleichmässig einzusprühen, ohne dieses völlig zu durchnässen. Dadurch kann es zu unerwünschten Flecken oder Randbildungen auf dem Gewebe kommen. Ein weiterer Nachteil besteht darin, dass sich die Spraydose oft trotz eines aufwendigen Sprühmechanismus nicht vollständig entleeren lässt.Spraying the laundry using a spray can is expensive, however, and is therefore mainly limited to use with shirts and blouses. In addition, the sliding effect achieved with the known dispersion described above is still not entirely satisfactory. It is also difficult to spray the tissue evenly without completely soaking it. This can lead to undesirable stains or margins on the fabric. Another disadvantage is that the spray can often cannot be completely emptied despite an elaborate spray mechanism.

Die Erfindung hat sich daher die Aufgabe gestellt, ein Wäschenachbehandlungsmittel zur Bügelerleichterung zur Verfügung zu stellen, welches im Vergleich zu der vorstehend beschriebenen bekannten Bügelhilfe durch eine erhöhte Gleitwirkung ein noch leichteres Bügeln gestattet und kostensparender in der Anwendung ist.The object of the invention is therefore to provide a laundry aftertreatment agent for facilitating ironing which, in comparison to the known ironing aid described above, permits even easier ironing due to an increased sliding action and is less expensive to use.

Diese Aufgabe wird durch das Wäschenachbehandlungsmittel gemäss Patentanspruch 1 gelöst, das vorzugsweise in den letzten Spülgang in der Waschmaschine eingebracht wird, so dass der Einsatz von kostenaufwendigen Sprühdosen entfällt.This object is achieved by the laundry aftertreatment agent according to claim 1, which is preferably introduced in the last rinse cycle in the washing machine, so that the use of expensive spray cans is omitted.

Das erfindungsgemässe Wäschenachbehandlungsmittel bedingt jedoch nicht nur einen höheren Gleiteffekt als die vorstehend beschriebene bekannte Bügelhilfe, sondern erhöht darüber hinaus auch noch die Saugfähigkeit des Gewebes gegenüber Wasser und verleiht dem Gewebe einen weichen flauschigen Griff, wobei ausserdem noch der gebügelten Wäsche eine leichte Appretur verliehen wird. Diese Wirkung des erfindungsgemässen Wäschenachbehandlungsmittels ist insofern überraschend, als eine Erzielung der Kombination der vorstehend geschilderten Eigenschaften bisher als unmöglich angesehen wurde, insbesondere die Kombination aus flauschigem Griff mit der Saugfähigkeit des Gewebes gegenüber Wasser. Zur Erzielung eines flauschigen Griffes wurden bisher als Wäschenachbehandlungsmittel sogenannte Weichspüler eingesetzt, die als Wirkstoffe quaternäre Ammoniumbasen mit langkettigen Alkylresten enthalten. Diese dem letzten Spülgang der Waschmaschine zugesetzten Mittel verleihen der Wäsche, insbesondere Frotteewaren und Trikotagen, einen weichen Griff, sie sind jedoch trotz einer gewissen Bügelerleichterung gegenüber unbehandelter Wäsche für die Nachbehandlung von Bügelwäsche ungeeignet. Ein gravierender Nachteil der Weichspüler ist ihre hydrophobierende Wirkung auf textilem Gewebe, insbesondere auf Baumwolle, verbunden mit einer starken Reduzierung der Saugfähigkeit der Wäsche.The laundry aftertreatment agent according to the invention not only results in a higher sliding effect than the known ironing aid described above, but also increases the absorbency of the fabric against water and gives the fabric a soft, fluffy feel, while also giving the ironed laundry a slight finish. This effect of the laundry aftertreatment agent according to the invention is surprising insofar as it has hitherto been considered impossible to achieve the combination of the properties described above, in particular the combination of a fluffy feel with the absorbency of the fabric against water. To achieve a fluffy feel, so-called fabric softeners, which contain quaternary ammonium bases with long-chain alkyl residues as active ingredients, have hitherto been used as laundry after-treatment agents. These agents added to the last rinse of the washing machine give the laundry, in particular terry goods and jersey, a soft feel, but they are unsuitable for the aftertreatment of ironing despite a certain amount of easier ironing compared to untreated laundry. A serious disadvantage of fabric softeners is their hydrophobic effect on textile fabrics, especially cotton, combined with a strong reduction in the absorbency of the laundry.

Das erfindungsgemässe Wäschenachbehandlungsmittel stellt daher nicht nur ein im Vergleich zu der bekannten Bügelhilfe verbessertes Bügelhilfsmittel dar, sondern gleichzeitig ein Mittel, durch welches der Körper und der Griff der Wäsche unter gleichzeitiger Erzielung einer weichmachenden Wirkung verbessert wird, ohne dass dabei die Saugfähigkeit der behandelten Wäsche beeinträchtigt wird. Darüber hinaus ermöglicht das erfindungsgemässe Wäschenachbehandlungsmittel das Bügeln trockener Wäsche, wobei gegenüber einer angefeuchteten Wäsche ein noch besserer Gleiteffekt erzielt wird. Nur bei hartnäckigen Knitterfalten ist ein leichtes Anfeuchten der Wäsche notwendig. Auch treten keine Nachteile beim Einsatz von Dampfbügeleisen ein. Bekanntlich kann ein Dampfbügeleisen nicht zum Bügeln von Wäsche eingesetzt werden, die mit dem vorstehend beschriebenen bekannten Bügelhilfsmittel behandelt worden ist.The laundry aftertreatment agent according to the invention is therefore not only an improved ironing aid compared to the known ironing aid, but at the same time a means by which the body and the feel of the laundry are improved while at the same time achieving a softening effect, without thereby impairing the absorbency of the treated laundry becomes. In addition, the laundry aftertreatment agent according to the invention enables ironing of dry laundry, an even better sliding effect being achieved compared to moistened laundry. It is only necessary to slightly dampen the laundry if there are persistent creases. There are also no disadvantages when using steam irons. As is known, a steam iron cannot be used for ironing laundry which has been treated with the known ironing aid described above.

In der DE-OS 26 31 419 wird ein Wäschenachbehandlungsmittel, das ebenfalls in den letzten Spülgang einer Waschmaschine eingebracht werden kann, beschrieben, das mitdem erfindungsgemässen Wäschenachbehandlungsmittel den Einsatz eines Siliconöls gemeinsam hat, in dem bekannten Falle werden jedoch keine alkoxylierten Stärken und Cellulosen eingesetzt, bei deren erfindungsgemässer Verwendung in überraschender Weise nicht nur die Bauschigkeit und die Gleitfähigkeit, sondern auch die Saugfähigkeit der behandelten Gewebe erhöht werden. In dem bekannten Falle werden geröstete Dextrine eingesetzt, die nur als Eindickungsmittel wirken.DE-OS 26 31 419 describes a laundry treatment agent which can also be introduced into the last rinse cycle of a washing machine and which has the use of a silicone oil in common with the laundry treatment agent according to the invention, but in the known case no alkoxylated starches and celluloses are used, when used according to the invention, not only the bulk and the lubricity, but also the absorbency of the treated tissues are surprisingly increased. In the known case, roasted dextrins are used which only act as thickeners.

Erfindungsgemäss werden Fettsäureamide im Gegensatzzu dem Einsatz von Fettsäureaminen im bekannten Falle verwendet. Diese bedingen eine geringere Schmutzredeposition und sind leichter hydrolysierbar als Amine und lassen sich damit besser auswaschen. Ausserdem sind sie leichter abbaubar und damit umweltfreundlicher als die im bekannten Falle eingesetzten Amine.According to the invention, fatty acid amides are used in contrast to the use of fatty acid amines in the known case. These require less dirt reduction and are easier to hydrolyze than amines and are therefore easier to wash out. In addition, they are more easily degradable and therefore more environmentally friendly than the amines used in the known case.

Insbesondere kommen Alkylsiliconöle, ganz besonders Methylsiliconöl mit einer Viskosität von 1000 bis 10 000 mm2· S-1, in Frage.The cationically dispersed silicone oil (component A) is a textile-relevant silicone oil with a viscosity between 500 and 50,000 mm , - S - 1 at 25 ° C, in particular 1000 to 10,000 mm , - s -1 at 25 ° C, as it is described, for example, in “Textilveredelung”, 19 (1984) No. 5 on pages 144 and 145. In particular, alkyl silicone oils, very particularly methyl silicone oil with a viscosity of 1000 to 10,000 mm 2 · S - 1 , are suitable.

Beispiel 3:Example 3:

Ermittlung der Bügelwerte:Determination of the ironing values:

Unter Einsatz des in Beispiel 2 hergestellten Mittels, das dem letzten Spülgang einer herkömmlichen Haushaltswaschmaschine in einer Menge von 50 bis 80 g zugesetzt wird, werden Wäschestücke aus Baumwolle und Baumwolle/Polyester-Mischgewebe, die zuvor unter Einsatz eines üblichen Waschmittels bei 95° C gewaschen wurden. zur Ermittlung der Bügelwerte behandelt. Der Bugeltest wird wie folgt durchgeführt:Using the agent produced in Example 2, which is added to the last rinse of a conventional household washing machine in an amount of 50 to 80 g, laundry items made of cotton and cotton / polyester blended fabrics, which were previously washed using a conventional detergent at 95 ° C. were. treated to determine the ironing values. The prick test is carried out as follows:

Ein Bügeleisen mit einer Temperatur von 200 ± 10°C wird über das Testgewebe mit konstanter, durch Gewichte einstellbarer Zugkraft entlang einer gleichbleibenden Messstrecke gezogen. Dieser Gleitversuch zerfällt in zwei Phasen, und zwar das «Anbügeln» des auf 30% Feuchtigkeit eingestellten Gewebes und das «Endbügeln» des trokkenen glatten Gewebes.An iron with a temperature of 200 ± 10 ° C is pulled over the test fabric with constant tensile force that can be adjusted by weights along a constant measuring path. This slide test breaks down into two phases, namely the "ironing" of the fabric adjusted to 30% moisture and the "final ironing" of the dry, smooth fabric.

Zu Vergleichszwecken wurde unbehandeltes Gewebe und mit einem herkömmlichen Bügelhilfsmittel behandeltes Gewebe dem Bügeltest unterzogen. Die dabei erhaltenen Ergebnisse sind in der folgenden Tabelle I zusammengefasst.

Figure imgb0007
For comparison purposes, untreated fabric and fabric treated with a conventional ironing aid were subjected to the ironing test. The results obtained are summarized in Table I below.
Figure imgb0007

Die Bügelwerte für das unbehandelte Gewebe schwanken um die in der Tabelle angegebenen Mittelwerte um + 10%. Das betrifft insbesondere die Gleitwerte. Die Ursache ist in der Ungleichmässigkeit der Oberflächenrauhigkeit des Gewebes zu suchen. Die mit «Bügelhilfe» und dem erfindungsgemässen Mittel ermittelten, deutlich niedrigeren Bügelwerte weisen eine wesentlich geringere Schwankungsbreite (maximal 5%) auf, da wegen der geringer werdenden Oberflächenrauhigkeit des behandelten Gewebes die Reproduzierbarkeit verbessert ist.The ironing values for the untreated fabric fluctuate around the mean values given in the table by + 10%. This applies in particular to the sliding values. The cause is to be found in the non-uniformity of the surface roughness of the fabric. The significantly lower ironing values determined with "ironing aid" and the agent according to the invention have a significantly smaller fluctuation range (maximum 5%), since the reproducibility is improved because of the decreasing surface roughness of the treated tissue.

Beispiel 4:Example 4:

Ermittlung der Auswaschbarkeit des erfindungsgemässen Mittels:Determination of the washability of the agent according to the invention:

Wäscheproben aus 100% Baumwollgewebe werden 5- bzw. 6mal bei 95° C und 60° C unter Einsatz eines herkömmlichen Waschmittels gewaschen und durch Zugabe des erfindungsgemässen Wäschenachbehandlungsmittels gemäss Beispiel 2 jeweils in dem letzten Spülgang in einer Menge von 80 g nachbehandelt.Laundry samples made from 100% cotton fabric are washed 5 or 6 times at 95 ° C. and 60 ° C. using a conventional detergent and aftertreated in an amount of 80 g in each case in the last rinse cycle by adding the laundry aftertreatment agent according to Example 2.

Zu Vergleichszwecken werden nichtbehandelte, in der gleichen Weise gewaschene Wäschestücke und mit «Bügelhilfe» behandelte Wäschestücke getestet. Als Untersuchungsmethode wird der Bügeltest herangezogen. Aus jeweils 6 einzelnen Gleittests werden die Mittelwerte gebildet, die in den beigefügten Figuren 1 und 2 aufgezeichnet sind.For comparison purposes, untreated items washed in the same way and items treated with "ironing aid" are tested. The ironing test is used as the test method. The mean values, which are recorded in the attached FIGS. 1 and 2, are formed from 6 individual sliding tests.

Die Bügelwerte von Fig. 1 bzw. Fig. 2 stellen die auf gleiche Zeit t = 10 s extrapolierte Zugkraft von bei 95° C (5mal) bzw. 60° C (6mal) gewaschenem und nachbehandeltem oder nicht nachbehandeltem Baumwollgewebe dar.The ironing values of FIGS. 1 and 2 represent the tensile force extrapolated at the same time t = 10 s of cotton fabric washed and post-treated or not post-treated at 95 ° C. (5 times) or 60 ° C. (6 times).

Wie die Fig. 1 und 2 zeigen, stellt sich in überraschender Weise schon mit der ersten Wiederholung der Nachbehandlung ein Bügelwert ein, der nur geringfügig vom Glättewert der ersten Nachbehandlung abweicht.As shown in FIGS. 1 and 2, the ironing value that surprisingly deviates only slightly from the smoothness value of the first aftertreatment already arises with the first repetition of the aftertreatment.

Daraus geht hervor, dass sich das erfindungsgemässe Wäschenachbehandlungsmittel sowohl bei einer 95° C-Wäsche als auch bei einer 60° C-Wäsche von der Wäscheprobe auswaschen lässt. Es treten daher keine nachteiligen Additionseffekte beim Einsatz des erfindungsgemässen Wäschenachbehandlungsmittels auf.It can be seen from this that the laundry aftertreatment agent according to the invention can be washed out of the laundry sample both when washing at 95 ° C. and when washing at 60 ° C. There are therefore no disadvantageous addition effects when using the laundry aftertreatment agent according to the invention.

Beispiel 5:Example 5:

Ermittlung der Bauschigkeit (Fülle):Determination of bulk (fullness):

Frotteetücher (100% Baumwolle) werden in herkömmlicher Weise gewaschen und im letzten Spülgang einmal mit dem Mittel des Beispiels 2 in einer Konzentration von 50 bis 80 g/20 Liter und einmal zum Vergleich mit einem herkömmlichen Weichspüler (auf der Basis von Distearyldimethylammoniumchlorid) in der gleichen Konzentration behandelt. Zu Vergleichszwecken werden auch nichtbehandelte Frotteetücher herangezogen. Insgesamt werden je 15 Frotteetücher zweimal bei 60° C gewaschen. Nach einem Lufttrocknen auf einem Wäscheständer werden die Frotteetücher der drei Testgruppen getrennt zu Stapeln aufeinandergelegt- Die Stapelhöhen werden nach 10 Minuten bestimmt und die Ergebnisse sind in der Tabelle 11 dargestellt.

Figure imgb0008
Terry towels (100% cotton) are washed in a conventional manner and in the last rinse once with the agent of Example 2 in a concentration of 50 to 80 g / 20 liters and once for comparison with a conventional fabric softener (based on distearyldimethylammonium chloride) treated with the same concentration. Untreated terry towels are also used for comparison purposes. A total of 15 terry towels are washed twice at 60 ° C. After air drying The terry towels of the three test groups are placed on top of one another in a stack on a drying rack. The stack heights are determined after 10 minutes and the results are shown in Table 11.
Figure imgb0008

Die Höhe des Stapels ist ein Mass für die Bauschigkeit der Frotteetücher und der Einzelfaserauflockerung. In überraschender Weise bewirkt das erfindungsgemässe Mittel eine noch grössere Stapelhöhe als der bekannte Weichmacher.The height of the stack is a measure of the bulkiness of the terry towels and the loosening of the individual fibers. The agent according to the invention surprisingly brings about an even greater stack height than the known plasticizer.

Beispiel 6:Example 6:

Ermittlung der Saugfähigkeit (Trocknungsvermögen) :Determination of absorbency (drying capacity):

Die Saugfähigkeit ist ein Massstab für die Aufnahmefähigkeit von Feuchtigkeit von textilen Geweben (Frottee). Die Saugfähigkeit wird mit Hilfe der Steighöhenmethode nach DIN 53294 ermittelt. Die jeweils 3 cm breiten und 25 cm langen Baumwollstreifen (100% Baumwollgewebe, nicht ausgerüstet, mit einem Flächengewicht von 140 g/cm2) werden mit einem Ende in destilliertes Wasser eingetaucht, das aufgrund der Kapillarkräfte im Gewebe je nach der Saugfähigkeit mehr oder weniger hoch aufsteigt. Die Steighöhen nach 5 Minuten Testzeit sind in der Tabelle III dargestellt.

Figure imgb0009
The absorbency is a measure of the absorption capacity of moisture from textile fabrics (terry cloth). The absorbency is determined using the rising height method according to DIN 53294. The 3 cm wide and 25 cm long cotton strips (100% cotton fabric, not equipped, with a basis weight of 140 g / cm 2 ) are immersed with one end in distilled water, which due to the capillary forces in the fabric more or less depending on the absorbency rises high. The climbing heights after a test period of 5 minutes are shown in Table III.
Figure imgb0009

Wie die vorstehende Tabelle III zeigt, wird durch das erfindungsgemässe Mittel die Saugfähigkeit gegenüber einer unbehandelten Gewebeprobe fast erreicht.As Table III above shows, the absorbency compared to an untreated tissue sample is almost achieved by the agent according to the invention.
