Abstract

The invention relates to a method for cleaning and restoring a hydrophobic effect of textiles (7) in a domestic washing machine. Said washing machine comprises devices (13, 12) for heating soapy water present in a wash tub (1) and for controlling treatment steps, and detergent reservoirs (111 and 112), at least one (112) of which is adapted to store an individual dose of a liquid washing auxiliary. According to said method, hydrophobic substances dissolved in the soapy water (6) are contacted with the textiles (7) during a treatment process Phl2 which is similar to a washing process PhW. The aim of the invention is to allow the above treatment to be carried out in domestic washing machines and to proceed in a coherent manner. Another aim of the invention is to substantially increase the hydrophobic effect achieved by this novel method. For this purpose, a washing process PhB, PhW for cleaning the textiles (7) while adding a special detergent which, in addition to the known dirt-removing effects, is also suitable for removing any detergent substances that may still adhere to the textiles, is carried out in the presence of an inflow of fresh water, and at the end thereof, the used soapy water (6) is pumped off. Once the washing process PhW is finished, the soapy water used for the preceding process is replaced and a multi-stage rinsing process PhSp is carried out for the textiles (7). After termination of the rinsing process, the last rinsing water is replaced and the hydrophobic substances are added to a newly supplied amount of fresh water, and a treatment process Phl1, Phl2, Phl3 for waterproofing the textiles (7) is carried out in an additive-containing soapy water V and the used additive-containing soapy water is removed without repeating the rinsing process.

Description

Verfahren zum Reinigen und Imprägnieren von Textilien Process for cleaning and impregnating textiles
[0001] Die Erfindung betrifft Verfahren zum Reinigen und Herstellen oder Wiederherstellen einer hydrophoben Wirkung von Textilien in einer Haushalt-Waschmaschine mit Einrichtungen zum Heizen einer in einem Laugenbehälter befindlichen Lauge und zum Steu- ern von Behandlungsvorgängen sowie mit Waschmittelvorratskammern, von denen mindestens eine zum Bevorraten einer Einzeldosis eines flüssigen Waschhilfsmittels ausgebildet ist, bei welchem Verfahren in der Lauge gelöste hydrophobierende Wirkstoffe während eines einem Waschvorgang ähnlichen Behandlungsvorgangs mit den Textilen in Kontakt gebracht werden. [0002] Funktionstextilien wie Oberbekleidung, die für den Schutz gegen Feuchtigkeit aus der Luft getragen wird, verlieren beim Gebrauch allmählich ihre Wasser abweisende Eigenschaft, ihre Imprägnierung. Durch Aufbringen einer hydrophobierenden Substanz auf die Textilfasern kann diese Eigenschaft hergestellt oder wieder hergestellt werden. Im Allgemeinen wird diese Behandlung von Textilien in einer gewerblichen Wäscherei oder einem Reinigungsunternehmen vorgenommen. Zunehmend wird aber auch gewünscht, solche Behandlungen in einer Haushalt-Waschmaschine durchführen zu können.[0001] The invention relates to processes for purifying and producing or restoring a hydrophobic effect of textiles in a household washing machine with means for heating a liquor in a tub and for controlling treatment processes as well as detergent storage chambers, at least one of which for storing a single dose of a liquid washing aid is formed, in which process hydrophobizing agents dissolved in the liquor are brought into contact with the textiles during a treatment process similar to a washing process. Functional textiles such as outerwear, which is worn for protection against moisture from the air, gradually lose their water-repellent property in use, their impregnation. By applying a hydrophobizing substance on the textile fibers, this property can be produced or restored. Generally, this treatment of textiles is done in a commercial laundry or cleaning company. Increasingly, however, it is also desired to be able to carry out such treatments in a household washing machine.
[0003] Daher werden im einschlägigen Handel Hydrophobierungsmittel angeboten, die für den Einsatz in Haushalt-Waschmaschinen zum Imprägnieren von Textilien geeignet sind. Solche Mittel bestehen vorwiegend aus Fluorkarbonharzen oder parafinhaltigen Mitteln. Die zu imprägnierenden Textilien sollen vorher in einem gesonderten Waschprogramm gut gereinigt werden. Das Imprägnieren wird dann bekannterweise separat in einem Standard-Waschvorgang in einer sogenannten langen Flotte vorgenommen, die dadurch gekennzeichnet ist, dass verhältnismäßig viel Lauge pro kg Wäsche verwendet wird. Eine empfohlene Menge des hydrophobierenden Wirkstoffs wird dabei vor Beginn dieses Standard-Waschvorgangs in die Hauptwaschkammer einer Waschmittel-Einspüleinrichtung eingefüllt und zusammen mit kaltem Frischwasser dem Laugenbehälter der Waschmaschine zugeführt. Dann wird unter Bewegen der Wäsche durch Drehen der Wäschetrommel die Imprägnierflotte mit der Wäsche in Kontakt gebracht, während sie im Laugenbehälter mittels einer Heizvorrichtung erwärmt wird. Die Dauer dieser Behandlung wird dabei vom Programm der Waschmaschinen-Steuerung vorgegeben, die u. a. auch vom Erreichen der vorgegebenen Temperatur der Imprägnierflotte bestimmt wird. Am Ende des Waschvorgangs wird die Wäsche mehrmals gespült, so dass die Menge des auf die Textilfasern der Wäsche aufziehenden Imprägniermittels wieder reduziert wird. Daher wird der durch das bekannte Verfahren erzielbare hydrophobe Effekt relativ gering. Außerdem wird der Vorgang zum Herstellen oder Wiederherstellen der Imprägnierung durchwegs getrennt von irgend einem anderen Behandlungsvorgang in der Waschmaschine durchgeführt, so dass der Benutzer der Waschmaschine zwei Mal die Beschi- ckungs- und Einstellhandlungen vornehmen muss und auch noch die volle Länge beider separaten Behandlungsprogramme abzuwarten hat. [0004] Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, das in einer Haushalt-Waschmaschine anwendbar ist und bei dem der Benutzer der Waschmaschine einen Behandlungsablauf vorfindet, mit dem die Textilien in einem durchgehenden Bearbeitungsprogramm sowohl gereinigt wie auch imprägniert werden können.Therefore, water repellents are offered in the relevant trade, which are suitable for use in household washing machines for impregnating textiles. Such agents consist predominantly of fluorocarbon resins or paraffin-containing agents. The textiles to be impregnated should be well cleaned beforehand in a separate washing program. The impregnation is then, as is known, carried out separately in a standard washing operation in a so-called long liquor, which is characterized in that a relatively large amount of liquor per kg of laundry is used. A recommended amount of hydrophobizing agent is filled before the start of this standard washing process in the main wash chamber of a detergent dispenser and fed together with cold fresh water to the tub of the washing machine. Then, while moving the laundry by rotating the laundry drum, the impregnating liquor is brought into contact with the laundry while being heated in the tub by means of a heater. The duration of this treatment is determined by the program of washing machine control, which among other things, is determined by reaching the predetermined temperature of the impregnating liquor. At the end of the washing process, the laundry is rinsed several times, so that the amount of impregnating agent applied to the textile fibers of the laundry is reduced again. Therefore, the achievable by the known method hydrophobic effect is relatively low. Moreover, the process of making or restoring the impregnation is consistently performed separately from any other treatment operation in the washing machine, so that the user of the washing machine has to perform the loading and setting operations twice and also has to wait the full length of both separate treatment programs , The invention has for its object to provide a method that is applicable in a household washing machine and in which the user of the washing machine finds a treatment process, with which the textiles can be both cleaned as well as impregnated in a continuous processing program.
[0005] Erfindungsgemäß wird diese Aufgabe durch die im Kennzeichen des Anspru- ches 1 angegebenen Merkmale in der Weise gelöst, dass ein Waschvorgang zum Reinigen der Textilen unter Zugabe eines Spezialwaschmittels, das neben seiner bekannten schmutzablösenden Wirkung auch zum Ablösen etwa noch vorhandener Waschmittel- Wirkstoffe von den Textilien geeignet ist, in eine zufließende Frischwassermenge durchgeführt und am Ende die benutzte Lauge abgepumpt wird, dass nach Ablauf des Wasch- Vorgangs unter Ersatz der jeweiligen Laugenfüllung des Vorgängervorgangs ein mehrstufiger Spülvorgang für die Textilien durchgeführt wird und dass nach Ende des Spülvorgangs unter Ersatz der letzten Spüllauge und Zugabe des hydrophobierenden Wirkstoffes in eine neu hinzugeführte Menge von Frischwasser ein Behandlungsvorgang zum Imprägnieren der Wäsche durchgeführt wird. [0006] Diese Maßnahmen führen dazu, dass ein Benutzer seinen textilen Wäscheposten in eine Waschmaschine laden kann, das kombinierte Reinigungs- und Imprägnierprogramm auswählt und startet. Er braucht sich bis zum Ende des Imprägniervorganges nicht mehr um seinen Wäscheposten zu kümmern.[0005] According to the invention, this object is achieved by the features specified in the characterizing part of claim 1 in such a way that a washing process for cleaning the textiles with the addition of a special detergent, in addition to its known soil-removing effect also for detaching still existing detergent active ingredients is suitable from the textiles, carried out in a flowing amount of fresh water and at the end the used liquor is pumped, that after the washing process with replacement of the respective lye filling of the predecessor process, a multi-stage rinsing process for the textiles is carried out and that after the end of the rinsing process with replacement the last rinse liquor and adding the hydrophobizing agent in a newly added amount of fresh water, a treatment process for impregnating the laundry is performed. These measures cause a user can load his textile laundry items in a washing machine that selects and starts the combined cleaning and impregnation program. He does not have to worry about his laundry until the end of the impregnation process.
[0007] Außerdem soll auch die Aufgabe gelöst werden, mit einem durchgehenden Bear- beitungsprogramm den erzielbaren hydrophoben Effekt im Vergleich zum Stand der Technik deutlich zu verbessern.[0007] In addition, the object is also to be achieved of significantly improving the achievable hydrophobic effect in comparison with the prior art with a continuous processing program.
[0008] Dieser Teil der Aufgabe kann insbesondere dann gelöst werden, wenn für den Behandlungsvorgang zum Imprägnieren der Laugenbehälter mit einer auf eine kurze Flotte, d. h. auf ein Verhältnis von Gewicht der Menge trockenen Textils zu Gewicht der Was- sermenge von kleiner als 1 :8, bemessenen Menge von Wasser gefüllt wird, die unter Bewegen der Textilien im Laugenbehälter auf eine Temperatur von mindestens 30° C aufgeheizt wird, ehe der hydrophobierendierende Wirkstoff zugegeben wird. [0009] Durch die Gesamtheit der vorstehenden Maßnahmen wird der hydrophobe Effekt auf den Textilien bedeutend erhöht. Die hohe Konzentration des Wirkstoffes in der Lauge verbessert das Aufziehverhalten des Wirkstoffes und verhindert gegenüber langen Flotten unnötig viel Wirkstoffverbrauch. Das Einbringen des Wirkstoffes in die bereits aufgeheizte Flotte verhindert Fleckenbildung auf den Textilien und verbessert nochmals das Aufzieh- verhalten des Wirkstoffes auf die Faser. Mit einer Behandlungsdauer von maximal 20 min erzielt man gute Ergebnisse. Längere Verweilzeiten verschwenden Energie ohne zusätzlichen Nutzen. Durch den Verzicht auf nachgeschaltete Spülgänge wird die Gefahr eines Verdünnens oder Abwaschens des Wirkstoffes von den Textilfasern vermieden.[0008] This part of the object can be achieved in particular if, for the treatment process for impregnating the tub with a dry liquor, ie a ratio of weight of the dry fabric to weight of the water quantity of less than 1: 8 , is metered quantity of water, which is heated while moving the textiles in the tub to a temperature of at least 30 ° C before the hydrophobizing agent is added. Through the entirety of the above measures, the hydrophobic effect on the textiles is significantly increased. The high concentration of the active ingredient in the liquor improves the Aufziehverhalten the active ingredient and prevents over long fleets unnecessarily much drug consumption. The introduction of the active ingredient into the already heated liquor prevents staining on the textiles and further improves the Aufzieh- behavior of the active ingredient on the fiber. With a maximum treatment time of 20 minutes, good results are achieved. Longer dwell times waste energy without added benefit. By dispensing with downstream rinses the risk of dilution or washing off of the active ingredient is avoided by the textile fibers.

As a result, the wetting and flooding of the laundry 7 is accelerated. To rotate the laundry drum 2 is an electric motor 14, which initiates its rotational movement via a belt transmission in the laundry drum 2. - A -
[0013] Am Boden des Laugenbehälters 1 ist eine Heizeinrichtung 13 angeordnet, die zur Beheizung der Lauge dient. Diese Lauge 6 gelangt durch Betätigung eines der Magnetventile 8 oder 9 in den Laugenbehälter 1 und besteht entweder nur aus Wasser oder aus einem Gemisch von Wasser und Waschhilfsmittel. In der Waschmitteleinspüleinrichtung 11 sind zwei Kammern 111 und 112 dargestellt, die jeweils beim öffnen des zugeordne- ten Magnetventils von Frischwasser durchflössen werden. Waschhilfsmittel, die sich in den Kammern befinden, werden dann vom Wasser durch die Leitung 10 hindurch aus der Waschmitteleinspüleinrichtung 11 in den Laugenbehälter 1 überführt. Lauge 6, die sich am Boden des Laugenbehälters 1 befindet, kann durch die Abflussleitung 17 und die Pumpe 18 in hier nicht näher dargestellter Weise nach außen befördert werden. [0014] Alle schalt- oder steuerbaren Einrichtungen, wie die Magnetventile 8 und 9, die Heizeinrichtung 13, der Trommelantriebsmotor 14 und die Laugenpumpe 18, werden von der Steuereinrichtung 12 der Waschmaschine geschaltet oder gesteuert.

This liquor 6 passes by operating one of the solenoid valves 8 or 9 in the tub 1 and consists either only of water or a mixture of water and detergent. In the Waschmitteleinspüleinrichtung 11 two chambers 111 and 112 are shown, which are respectively flowed through the opening of the associated solenoid valve of fresh water. Auxiliary washing agents, which are located in the chambers are then transferred from the water through the line 10 from the Waschmitteleinspüleinrichtung 11 in the tub 1. Lye 6, which is located at the bottom of the tub 1, can be transported through the drain line 17 and the pump 18 in a manner not shown here to the outside. All switchable or controllable devices, such as the solenoid valves 8 and 9, the heater 13, the drum drive motor 14 and the drain pump 18 are switched or controlled by the controller 12 of the washing machine. For measuring the temperature of the liquor 6 also serves a temperature sensor 15, which passes its measuring signals via the reporting line to an evaluation device 121 in the control device 12.
[0015] Gemäß der Erfindung wird die in Fig. 1 dargestellte Waschmaschine beispielsweise so betrieben, wie es in Fig. 2 und 3 dargestellt ist. In den Diagrammen gilt der Maßstab auf der Ordinate ausschließlich für die Drehzahl der Wäschetrommel 2; den anderen Parametern ist kein Maßstab zugeordnet. Für den Betrieb der Waschmaschine wird zu- nächst das Magnetventil 8 geöffnet, um Wasser über die - in diesem Beispiel zur vorbereitenden Reinigung zu imprägnierender Wäschestücke mit Spezialwaschmittel gefüllte - Waschmittelkammer 111 und die Leitung 10 in den Laugenbehälter 1 einzufüllen. Das Wasser führt dieses Spezialmittel mit in den Laugenbehälter 1, wo es sich verteilt.According to the invention, the washing machine shown in Fig. 1, for example, operated as shown in FIGS. 2 and 3. In the diagrams, the scale on the ordinate applies only to the speed of the laundry drum 2; no scale is assigned to the other parameters. For the operation of the washing machine, the solenoid valve 8 is initially opened in order to charge water via the detergent chamber 111 filled with laundry detergent to be impregnated in this example for the preparatory cleaning and the line 10 into the tub 1. The water carries this special agent into the tub 1, where it is distributed.
[0016] Zusammen bilden sie die Wasch-Lauge. Zu Beginn des in Fig. 2 dargestellten Waschvorganges, der aus den drei Phasen PhB zum Benetzen der Wäsche, PhW zum Waschen der Wäsche und PhSp zum Klarspülen der Wäsche besteht, wird die Wäschetrommel 2 entsprechend der fetten durchgezogenen Diagrammlinie n nur mit einer geringeren Drehzahl (z.B. 23 Upm) angetrieben, als es nach dem Benetzen der Fall ist. Außerdem wird in der Benetzungsphase PhB die Trommel 2 nur in Pfeilrichtung 16 angetrieben, in der die Schöpfeinrichtungen 5 am Trommelmantel ihre volle Wirkung entfalten.Together they form the wash liquor. At the beginning of the washing process shown in FIG. 2, which consists of the three phases PhB for wetting the laundry, PhW for washing the laundry and PhSp for rinsing the laundry, the laundry drum 2 corresponding to the bold continuous diagram line n only has a lower speed (FIG. eg 23 rpm), as it does after wetting. In addition, in the wetting phase PhB the drum 2 is driven only in the direction of arrow 16, in which the scooping devices 5 unfold their full effect on the drum casing.
[0017] Während der Waschphase PhW wird die Wäschetrommel 2 dauernd reversierend mit beispielsweise 50 Upm angetrieben, so dass die Wäsche intensiv mit der während der Benetzungsphase bereits aufgeheizten Wasch-Lauge in Berührung kommt. Am Ende der Waschphase PhW wird die Wasch-Lauge abgepumpt und durch eine Frischwasser- Laugenfüllung ersetzt. Dazu kann das zufließende Wasser beispielsweise durch die bereits geleerte Waschmittelkammer 111 geleitet werden. Die Spülphase PhSp enthält mehrere Stufen mit immer wieder neuen Frischwasserfüllungen, so dass die Wasch-Lauge extrem stark verdünnt wird. Es soll nämlich möglichst kein Rückstand von Spezialwasch- mittel in der Wäsche verbleiben. Die Zahl der Spülstufen ist daher auf diese Forderung einzustellen.During the washing phase PhW the laundry drum 2 is driven continuously reversing with, for example, 50 rpm, so that the laundry comes into intensive contact with the already during the wetting phase washed wash liquor. At the end of Washing phase PhW is pumped out of the washing solution and replaced with a fresh water solution. For this purpose, the inflowing water can be passed, for example, through the already emptied detergent chamber 111. The rinsing phase PhSp contains several stages with constantly new fresh water fillings, so that the washing lye is extremely diluted. As far as possible, no residue of special detergents should remain in the laundry. The number of rinsing stages is therefore set to this requirement.
[0018] Im übrigen können die hier beschriebenen Vorgänge in den Phasen PhB, PhW und PhSp gemäß den aktuellen Erkenntnissen über das Benetzen, Waschen und Spülen von Wäsche variiert werden. [0019] Unmittelbar anschließend folgt gemäß Fig. 3 auf den Waschvorgang der Imprägniervorgang. Die in der ersten Phase PhM eingefüllte Wassermenge ist dem in der Wäschetrommel 1 lagernden Wäscheposten 7 abzüglich einer Menge angemessen, die vom Spülvorgang noch in der Wäsche verblieben ist, und einer weiteren Menge, die zum späteren Zuführen des hydrophobierenden Wirkstoffes benötigt wird. Diese Wassermenge läuft abermals über das Magnetventil 8 durch die bereits geleerte Waschmittelkammer 111 in den Laugenbehälter, wo sie zunächst aufgeheizt wird. Erst wenn die Laugentemperatur etwa 30° oder 40°C beträgt, wird über das jetzt geöffnete Magnetventil 9 die restliche Wassermenge zusammen mit dem in der Waschmittelkammer 112 bevorrateten hydrophobierenden Wirkstoff als hoch konzentrierte Imprägnier-Lauge durch die Leitung 10 in den Laugenbehälter 1 geführt und bildet zusammen mit der bereits aufgeheizten Lauge an seinem Boden ein Niveau Nv, das die Wäschetrommel 2 mindestens berührt. Auf diese Weise sind die Schöpfeinrichtungen 5 an der Wäschetrommel 2 in der Lage, bei hier schon einsetzender Trommeldrehung Imprägnier-Lauge aus dem Laugenbehälter 1 aufzunehmen, nach oben zu transportieren und über die Wäsche 7 abzuregnen. Damit sich der Wäscheposten nicht verknäuelt, wird die Trommel 2 reversierend angetrieben. Diese Antriebsweise ist hier nur schematisch angedeutet und kann in beliebiger Weise variiert werden, um die Durchflutung der Wäsche zu fördern.Incidentally, the processes described here in the phases PhB, PhW and PhSp can be varied according to the current knowledge about the wetting, washing and rinsing of laundry. Immediately thereafter follows according to FIG. 3 on the washing process of the impregnation process. The amount of water charged in the first phase PhM is appropriate to the laundry lot 7 stored in the laundry drum 1 minus an amount remaining in the laundry from the rinsing process and another amount needed for later supplying the hydrophobizing agent. This amount of water again passes through the solenoid valve 8 through the already emptied detergent chamber 111 into the tub, where it is first heated. Only when the liquor temperature is about 30 ° or 40 ° C, the remaining amount of water is guided through the line 10 in the tub 1 via the now open solenoid valve 9 together with the stocked in the detergent chamber 112 hydrophobizing agent as a highly concentrated impregnating liquor together with the already heated liquor at its bottom a level N v , which at least touches the laundry drum 2. In this way, the scooping devices 5 on the laundry drum 2 are able to pick up impregnating liquor from the tub 1 when the drum is already rotating, transport it upwards and rinse it over the laundry 7. So that the laundry items do not get tangled, the drum 2 is reversibly driven. This mode of operation is indicated here only schematically and can be varied in any way to promote the flooding of the laundry.
[0020] Am Ende der Phase PhM , in der die Imprägnier-Lauge 6 (Diagrammlinie V) im Laugenbehälter entsprechend der dünnen Diagrammlinie ύ- vor der Zugabe des hydro- phobierenden Wirkstoffes durch die Heizeinrichtung 13 auf die Temperatur von maximal 30° oder 400C aufgeheizt wird, ist die Imprägnier-Lauge gut vermischt und gleichmäßig im Wäscheposten 7 verteilt. Durch die Vorbenetzung der Wäsche aus dem vorangegangenen Spülgang PhSp kann bei der Zugabe des hydrophobierenden Wirkstoffes die plötzlich auftretende Konzentration der Imprägnier-Lauge der Wäsche 7 nichts anhaben; sie stellt keine Gefahr mehr dar für eine ansonsten mögliche Verfleckung mit hohen Wirkstoffkonzentrationen. Während der nunmehr beginnenden Phase Phl2 wird die Trommel weiterhin angetrieben und kämmt mit ihren Schöpfvorrichtungen 5 kräftig durch die Imprägnier- Lauge 6. Dadurch wird die Wäsche beispielsweise maximal 20 min lang intensiv von hydrophobierender Lauge durchflutet. Verbesserte hydrophobierende Wirkstoffe lassen auch eine verkürzte Einwirkdauer von weniger als 20 min zu.[0020] At the end of phase PhM in which the impregnating liquor 6 (graph line V) in the tub corresponding to the thin graph line ύ- before the addition of hydro- repellent active ingredient through the heater 13 to the temperature of 30 ° or 40 0 C is heated, the impregnation liquor is well mixed and evenly distributed in the laundry 7 items. By pre-wetting the laundry from the previous rinse PhSp can be in the addition of the hydrophobizing agent suddenly occurring concentration of the impregnating liquor of the laundry 7 do not damage; it is no longer a danger for an otherwise possible staining with high concentrations of active ingredient. During the now beginning phase Phl2, the drum continues to be driven and meshes with its scooping devices 5 vigorously through the impregnating lye 6. As a result, the laundry, for example, flooded intensively for a maximum of 20 minutes of hydrophobicizing liquor. Improved hydrophobizing agents also allow for a shorter exposure time of less than 20 minutes.
[0021] Am Ende der Phase Phl2 - nämlich bei Beginn der Phase Phl3 - setzt zunächst die Trommelbewegung aus und der Betrieb der Laugenpumpe 18 ein. Dadurch wird die im Laugenbehälter 1 befindliche freie Imprägnier-Lauge durch die Abflussleitung ge- schwind von der Pumpe 18 abgesaugt und abgeführt. Sehr bald nach Beginn des Pumpenbetriebs wird dann der Trommelantrieb auf Schleuderbetrieb gesetzt. Im dargestellten Diagramm sind die hohen Drehzahlen aus Platzgründen gestaucht dargestellt. Jedenfalls sind drei Schleuderimpulse mit jeweils sich steigernden Enddrehzahlen zu erkennen, durch die immer mehr gebundene Lauge aus der Wäsche ausgetrieben wird. Im letzten Schleuderintervall kann die Endschleuderdrehzahl durchaus 800 Upm erreichen. Hier wird bewusst auf das sonst übliche Vor-Spülen mit klarem Wasser verzichtet, damit möglichst viel vom hydrophobierenden Wirkstoff, der auf die Wäschefasern aufgezogen ist, dort auch erhalten bleibt. Während der Schleuderintervalle bleibt die Laugenpumpe 18 in Betrieb, damit die von der Wäsche ausgetriebene Lauge rasch abgeführt wird. At the end of the phase Phl2 - namely at the beginning of the phase Phl3 - sets first the drum movement and the operation of the drain pump 18 a. As a result, the free impregnating liquor present in the tub 1 is suctioned off and discharged by the pump 18 through the drain line. Very soon after the start of the pump operation, the drum drive is then set to spin mode. In the diagram shown, the high speeds are shown compressed because of space. In any case, three centrifugal pulses are recognizable, each with increasing final speeds, is driven by the more and more bound liquor from the laundry. In the last spin interval, the final spin speed can reach 800 rpm. Here is deliberately dispensed with the usual pre-rinsing with clear water, so that as much of the hydrophobizing agent that is grown on the laundry fibers, there is also preserved. During the spin intervals, the drain pump 18 remains in operation, so that the leached from the laundry liquor is discharged quickly.
