Definitions

  • the present invention relates to a detergent product which consists of a water-insoluble, water-permeable bag containing the amount of a powdery or granular detergent required for a washing process.
  • Detergent pre-portioned in bags has long been known. They offer the advantage that the user does not have to measure the amount of detergent required for a washing process, that low requirements must be placed on the flow, the grain size distribution and the appearance of the detergent, that the user himself with the detergent and its possibly irritating components of the skin does not come into contact and that the detergents contained in bags made of water-insoluble materials are not released into the lye in undissolved or finely dispersed form and therefore no detergent losses occur which occur when unpackaged detergent is added in machines that do not have a sealed lye sump or in which the contents of the alkali sump are not also pumped around.
  • the properties of the bag are subject to a variety of requirements.
  • the bag must be so tight on the one hand that fine-particle detergent components remain enclosed, and on the other hand the bag must be permeable to water in such a way that the detergent can be quickly extracted or washed out by the 2 -
  • wash water is possible; the bag materials must be able to be processed on conventional filling and packaging systems, which includes in particular the ability to be welded with permanently heated welding jaws. Furthermore, the bag materials must be insensitive to the contents of the bag and must not be so expensive that their use is not worthwhile. Since the previously known detergent portion bags did not have all of these required properties at the same time, such detergent products have not been able to establish themselves on the market.
  • Water-insoluble, water-permeable sachets for particulate detergents are described, for example, in EP-A-11968.
  • the bags described there are made of a material which at least partially consists of polypropylene fibers.
  • the bag material can also contain cellulose fibers, polyester fibers, polyamide fibers or mixtures thereof. According to the teaching of the patent application mentioned, preferred materials consisting exclusively of polypropylene fibers or consisting at least for the most part of polypropylene fibers are preferred. However, this material presents difficulties when it is processed into bags.
  • the present invention therefore relates to a detergent product comprising a particulate detergent in a water-insoluble, water-permeable bag made of flat textile material, the fibers of which are made of polypropylene and another consist of organic polymeric material, the fibers consisting exclusively of coated bi-component fibers made of an inner core made of polypropylene with a crystallinity of 40 to 60% determined by means of X-ray structure analysis, which is coated with polyethylene of a crystallinity of 50 to 70% .
  • Bag materials that meet the requirements described above can be produced from such fibers. Above all, the demand for easy weldability on conventional machines with permanently heated welding jaws is guaranteed by materials made from these so-called bi-component fibers. It is also possible to manufacture sealed edge bags (flat bags), for which pulse welding technology cannot normally be used.
  • a bag material which is suitable with regard to dust-tightness and water permeability is, for example, a non-woven textile fabric with an air permeability of 200 to 600 liters per square meter and second at a pressure difference of 10 millimeters of water.
  • the adsorption capacity measured according to a test method which is described in the US Federal Specifications UU-T-595B and which has been modified for the present application according to information from DE-A-1965470, is in the range from 1.5 to 7 r in particular at about 5.
  • the tensile strength of such materials in the dry and in the wet state is about 50 to about 70 Newtons (measured in the longitudinal direction).
  • Such a material is commercially available, for example, from Ch. H. Sandler, Schwarzenbach / Saale under the name Sawabond VP 59/85/207.
  • the basis weight of such a bag material is approximately 40 to 60 grams per square meter.
  • the degree of filling of the pouch is about 40 to about 75% of the pouch volume.
  • the security against dissolution is determined by placing a bag filled with detergents together with the desired amount of textiles in an automatic washing machine filled, the washing machine starts with the normal program and removes the bag 10 minutes after the start of the washing program and relates the residue in the bag to the sample weight. Good dissolving reliability is achieved if, under these conditions, at least 80% by weight of the weighed-in amount of detergent is dissolved after 10 minutes.
  • the savings in detergent due to better utilization of the detergent compared to the usual procedure in which detergent is rinsed in at the start of the wash cycle is approximately 20 to 30% .
  • the detergent products according to the invention can achieve better washing results with the detergent dosage being of the same weight than if the same detergent is washed into the washing machine with the washing water at the start of the washing process.
  • the stability of the textile fabric can be improved by mechanically stabilizing the surface by means of thermal consolidation, as a result of which the fibers used for its production are fixed in their position within the fabric.
  • the detergent pouch can contain one or more compartments, and if the pouch contains several compartments, the compartments can contain different detergent components that are incompatible or poorly compatible with one another. If all four or three edges of such a bag are firmly welded, the bag or the chambers do not open during washing. But it is possible to make one or more welds weak or by special measures, for example weaken by inserting a separating layer so that the bag or chamber opens in the course of the washing process and releases its contents to the washing liquor. However, the bag is preferably welded firmly and only releases its contents through the fine pores of the bag material.
  • the bag can contain any particulate detergent.
  • the grain size distribution of the detergent can vary over a wide range, for example in the range from 0.01 to 3 millimeters.
  • the bag size must not be less than a certain lower size, since otherwise the bag can remove itself from the textiles to be circulated during the washing process and settle in a blind spot of the washing machine, for example at the filler opening.
  • Suitable bags therefore have, as already stated above, a minimum edge length of about 5 centimeters and a surface size of 30 to 300 square centimeters (measured on one side).
  • the bags preferably have a thickness of 10, in particular 15, millimeters at at least one point.
  • Another object of the present invention is the use of a textile fabric as described above as bag material for a detergent product of the type mentioned.
  • the detergent-containing bags can be produced individually or in a group. Depending on the detergent requirement, the consumer can then separate and use one or more bags. It is also possible to package paste-like detergents in the bags instead of particulate detergents. In this case, it is expedient to seal the bag material on the inside and / or outside with a coating that is soluble or removable in water.
  • the detergent product described is a convenient and reliable possibility for metering detergent. Only small requirements are placed on the particle size distribution, the flowability and the appearance of the particulate detergent packaged in this way, compared to detergents not packaged in sachets.
  • the consumer does not come into contact with the actual detergent, which is particularly important for consumers who are allergic to detergent components. Since the detergent cannot be removed from the washing process by settling in the suds of the washing machine, a marked saving in detergent results and a correspondingly reduced wastewater load when the washing result is excellent. Dust-fine detergent fractions remain enclosed in the bag until use and coarse detergent particles are reliably removed or washed out.
  • This example shows the superior washing performance of the detergent product according to the invention in comparison with a conventional addition of the same detergent, with the same weight, the te-shaped detergent being washed by the washing water at the beginning of the washing process from the induction chamber of an automatic household machine type Miele W 433 into the Washing drum is washed in.

Abstract

En utilisant dans une machine à laver automatique des portions d'un produit de lessive contenues dans des sachets flexibles en un matériau textile plat perméable à l'eau, on obtient un lavage amélioré et/ou on économise davantage le produit de lessive par comparaison au dosage usuel du produit de lessive au moyen du compartiment doseur de la machine à laver, à condition que ledit sachet satisfasse certains critères, pour ce qui est de la nature des fibres utilisées pour fabriquer le matériau dont il se compose, éventuellement pour ce qui est de la perméabilité à l'air et de la capacité d'adsorption dudit matériau, des dimensions géométriques du sachet et de son degré de remplissage.By using portions of a detergent contained in flexible sachets of a flat, water-permeable textile material in an automatic washing machine, an improved wash is obtained and / or the detergent is further saved compared to usual dosage of the detergent by means of the dosing compartment of the washing machine, provided that the said sachet satisfies certain criteria, with regard to the nature of the fibers used to manufacture the material of which it is composed, possibly with regard to the air permeability and the adsorption capacity of said material, the geometric dimensions of the bag and its degree of filling.

Description

Waschmittelerzeuqnis Detergent products
Die vorliegende Erfindung betrifft ein Waschmittelerzeugnis, das aus einem wasserunlöslichen, wasserdurchlässigen Beutel, enthal¬ tend die für einen Waschvorgang erforderliche Menge eines pul- verför igen oder körnigen Waschmittels, besteht.The present invention relates to a detergent product which consists of a water-insoluble, water-permeable bag containing the amount of a powdery or granular detergent required for a washing process.
In Beuteln vorportionierte Waschmittel sind seit langem bekannt. Sie bieten den Vorteil, daß der Verwender die für einen Wasch¬ vorgang erforderliche Waschmittelmenge nicht abzumessen braucht, daß an die Rieselförmigkeit, die Korngrößenverteilung, das Aus¬ sehen des Waschmittels geringe Anforderungen gestellt zu werden brauchen, daß der Verwender selbst mit dem Waschmittel und dessen möglicherweise hautreizenden Bestandteilen nicht in Berührung kommt und daß die in Beuteln aus wasserunlöslichen Materialien enthaltenen Waschmitteln nicht ungelöst oder feindispergiert an die Lauge abgegeben werden und dadurch keine Waschmittelverluste entstehen, die bei der Zugabe von unverpacktem Waschmittel in solchen Maschinen auftreten, die keinen verschlossenen Laugensumpf haben oder bei denen der Inhalt des Laugensumpfes nicht mit umge¬ pumpt wird. Um aber alle diese vorteilhaften Eigenschaften von Waschmitteln in Portionsbeuteln ausnutzen zu können, werden an die Eigenschaften des Beutels vielfältige Anforderungen gestellt. So muß der Beutel einerseits so dicht sein, daß feinteilige Wasch¬ mittelbestandteile eingeschlossen bleiben, andererseits muß der Beutel für Wasser aber so durchlässig sein, daß ein schnelles Herauslösen oder Herausschwemmen des Waschmittels durch das 2 -Detergent pre-portioned in bags has long been known. They offer the advantage that the user does not have to measure the amount of detergent required for a washing process, that low requirements must be placed on the flow, the grain size distribution and the appearance of the detergent, that the user himself with the detergent and its possibly irritating components of the skin does not come into contact and that the detergents contained in bags made of water-insoluble materials are not released into the lye in undissolved or finely dispersed form and therefore no detergent losses occur which occur when unpackaged detergent is added in machines that do not have a sealed lye sump or in which the contents of the alkali sump are not also pumped around. However, in order to be able to take advantage of all these advantageous properties of detergents in sachets, the properties of the bag are subject to a variety of requirements. Thus the bag must be so tight on the one hand that fine-particle detergent components remain enclosed, and on the other hand the bag must be permeable to water in such a way that the detergent can be quickly extracted or washed out by the 2 -
Waschwasser möglich ist; die Beutelmaterialien müssen sich auf üblichen Abfüll- und Verpackungsanlagen verarbeiten lassen, wozu insbesondere auch die Verschweißbarkeit mit dauerbeheizten Schweißbacken zählt. Ferner müssen die Beutelmaterialien ihrer¬ seits unempfindlich gegenüber dem Beutelinhalt sein und dürfen nicht so teuer sein, daß sich ihr Einsatz nicht lohnt. Da die bisher bekannten Waschmittelportionsbeutel nicht alle diese erforderlichen Eigenschaften gleichzeitig besaßen, haben sich derartige Waschmittelerzeugnisse auf dem Markt nicht durchsetzen können.Wash water is possible; the bag materials must be able to be processed on conventional filling and packaging systems, which includes in particular the ability to be welded with permanently heated welding jaws. Furthermore, the bag materials must be insensitive to the contents of the bag and must not be so expensive that their use is not worthwhile. Since the previously known detergent portion bags did not have all of these required properties at the same time, such detergent products have not been able to establish themselves on the market.
Wasserunlösliche, wasserdurchlässige Portionsbeutel für teilchen- för ige Waschmittel sind beispielsweise in der EP-A-11968 be¬ schrieben. Die dort beschriebenen Beutel sind aus einem Material angefertigt, das wenigstens zum Teil aus Polypropylenfasern be¬ steht. Zusätzlich kann das Beutelmaterial aber auch noch Cellu- losefasern, Polyesterfasern, Polyamidfasern oder deren Mischungen enthalten. Nach der Lehre der genannten Patentanmeldung sind Beu¬ teImaterialien aus ausschließlich Polypropylenfasern oder aus wenigstens zum größten Teil aus Polypropylenfasern bestehend be¬ vorzugt. Bei der Verarbeitung zu Beuteln bereitet dieses Material aber Schwierigkeiten.Water-insoluble, water-permeable sachets for particulate detergents are described, for example, in EP-A-11968. The bags described there are made of a material which at least partially consists of polypropylene fibers. In addition, the bag material can also contain cellulose fibers, polyester fibers, polyamide fibers or mixtures thereof. According to the teaching of the patent application mentioned, preferred materials consisting exclusively of polypropylene fibers or consisting at least for the most part of polypropylene fibers are preferred. However, this material presents difficulties when it is processed into bags.
Es wurde nun gefunden, daß verbesserte Beutelmaterialien in aus¬ gezeichneter Weise für den geschilderten Verwendungszweck geeignet sind.It has now been found that improved bag materials are outstandingly suitable for the use described.
Gegenstand der vorliegenden Erfindung ist daher ein Waschmittel¬ erzeugnis, enthaltend ein teilchenförmiges Waschmittel in einem wasserunlöslichen, wasserdurchlässigen Beutel aus flächigem tex- tilem Material, dessen Fasern aus Polypropylen und einem weiteren organischen polymeren Material bestehen, wobei die Fasern aus¬ schließlich aus umhüllten Bi-Komponenten-Fasern aus einem inneren Kern aus Polypropylen mit einer mittels Röntgenstrukturanalyse ermittelten Kristallinität von 40 bis 60 %, der mit Polyethylen einer Kristallinität von 50 bis 70 % umhüllt ist, bestehen.The present invention therefore relates to a detergent product comprising a particulate detergent in a water-insoluble, water-permeable bag made of flat textile material, the fibers of which are made of polypropylene and another consist of organic polymeric material, the fibers consisting exclusively of coated bi-component fibers made of an inner core made of polypropylene with a crystallinity of 40 to 60% determined by means of X-ray structure analysis, which is coated with polyethylene of a crystallinity of 50 to 70% .
Aus derartigen Fasern lassen sich Beutelmaterialien herstellen, die den oben geschilderten Anforderungen entsprechen. Vor allem die Forderung nach der leichten Verschweißbarkeit auf üblichen Maschinen mit dauerbeheizten Schweißbacken wird durch Materialien aus diesen sogenannten Bi-Komponenten-Fasern gewährleistet. Es ist damit möglich, auch Siegelrandbeutel (Flachbeutel) herzustellen, bei denen die Impulsschweißtechnik normalerweise nicht angewendet werden kann.Bag materials that meet the requirements described above can be produced from such fibers. Above all, the demand for easy weldability on conventional machines with permanently heated welding jaws is guaranteed by materials made from these so-called bi-component fibers. It is also possible to manufacture sealed edge bags (flat bags), for which pulse welding technology cannot normally be used.
Besonders wertvolle Eigenschaften weisen' dabei Fasern auf, bei denen der Polypropylenanteil größer ist als der Polyethylenanteil und insbesondere in einem Gewichtsverhältnis von 3 : 2 bis 9 : 1 liegt. Aus solchen Materialien lassen sich außergewöhnlich feine Fasern herstellen, die sich dementsprechend zu sehr dichten, aber trotzdem gut wasserdurchlässigen Beutelmaterialien verarbeiten lassen. In diesem Sinne geeignete Fasern weisen einen Titer von 0,7 bis 3 dTex auf (dTex = Gewicht eines 10.000 Meter langen Fadens in Gramm).Particularly valuable properties have 'where fibers in which the polypropylene content is greater than the proportion of polyethylene, and in particular in a weight ratio of 3: 1: 2 to ninth Such materials can be used to produce exceptionally fine fibers, which can accordingly be processed into very dense, but nevertheless water-permeable bag materials. Suitable fibers in this sense have a titer of 0.7 to 3 dTex (dTex = weight of a 10,000 meter long thread in grams).
Ein hinsichtlich Staubdichtigkeit und Wasserdurchlässigkeit ge¬ eignetes Beutelmaterial stellt beispielsweise ein nichtverwobenes textiles Flächengebilde mit einer Luftdurchlässigkeit von 200 bis 600 Liter pro Quadratmeter und Sekunde bei einer Druckdifferenz von 10 Millimeter Wassersäule dar. Die Adsorptionskapazität, gemessen nach einer Testmethode, die in den U.S. Federal Specifications UU-T-595B beschrieben ist, und die für den vorliegenden Anwendungszweck nach Angaben der DE-A-1965470 modifiziert wurde, liegt im Bereich von 1,5 bis 7r insbesondere bei etwa 5.A bag material which is suitable with regard to dust-tightness and water permeability is, for example, a non-woven textile fabric with an air permeability of 200 to 600 liters per square meter and second at a pressure difference of 10 millimeters of water. The adsorption capacity, measured according to a test method which is described in the US Federal Specifications UU-T-595B and which has been modified for the present application according to information from DE-A-1965470, is in the range from 1.5 to 7 r in particular at about 5.
Die Reißfestigkeit derartiger Materialien im trockenen wie im nassen Zustand liegt bei etwa 50 bis etwa 70 Newton (in Längs¬ richtung gemessen). Ein derartiges Material ist beispielsweise von der Firma Ch. H. Sandler, Schwarzenbach/Saale unter der Bezeich¬ nung Sawabond VP 59/85/207 im Handel. Das Flächengewicht eines derartigen Beutelmaterials beträgt circa 40 bis 60 Gramm pro Quadratmeter. Aus derartigem Material gefertigte Beutel mit einer Kantenlänge im Bereich zwischen 5 bis 20, vorzugsweise 8 bis 15 Zentimeter, die eine Größe von 30 bis 300, vorzugsweise 60 bis 200 Quadratzentimeter Oberfläche (einseitig gemessen) haben, können eine für einen Waschvorgang ausreichende Menge eines teilchenför- migen Waschmittels, worunter sowohl feinpulverige als grobkörnige Waschmittel zu verstehen sind, aufnehmen. Je nach Art und Liter¬ gewicht des Waschmittels enthalten geeignete Beutel, die entweder an drei oder an vier Seiten nach dem Befüllen verschweißt werden, etwa 20 bis 120 Gramm Waschmittel.The tensile strength of such materials in the dry and in the wet state is about 50 to about 70 Newtons (measured in the longitudinal direction). Such a material is commercially available, for example, from Ch. H. Sandler, Schwarzenbach / Saale under the name Sawabond VP 59/85/207. The basis weight of such a bag material is approximately 40 to 60 grams per square meter. Bags made from such a material with an edge length in the range between 5 to 20, preferably 8 to 15 centimeters, which have a size of 30 to 300, preferably 60 to 200 square centimeters surface (measured on one side), can contain a sufficient amount of a particulate for a washing process - Take up detergent, which includes both fine-powdered and coarse-grained detergents. Depending on the type and liter weight of the detergent, suitable bags, which are sealed either on three or on four sides after filling, contain about 20 to 120 grams of detergent.
Im Hinblick auf eine ausreichende Auflösesicherheit des Waschmit¬ tels ist es wichtig, daß der Füllgrad des Beutels etwa 40 bis etwa 75 % des Beutelvolumens beträgt. Die Auflösesicherheit wird ermit¬ telt, indem man einen mit Waschmitteln gefüllten Beutel zusammen mit der Sollmenge von Textilien in eine automatische Waschmaschine einfüllt, die Waschmaschine mit dem Normalprogramm startet und 10 Minuten nach Beginn des Waschprogramms den Beutel entnimmt und den Rückstand im Beutel auf die Einwaage bezieht. Eine gute Auflöse¬ sicherheit ist erreicht, wenn unter diesen Bedingungen nach 10 Minuten wenigstens 80 Gew.-% der eingewogenen Waschmittelmenge aufgelöst sind.In order to ensure that the detergent is sufficiently safe to dissolve, it is important that the degree of filling of the pouch is about 40 to about 75% of the pouch volume. The security against dissolution is determined by placing a bag filled with detergents together with the desired amount of textiles in an automatic washing machine filled, the washing machine starts with the normal program and removes the bag 10 minutes after the start of the washing program and relates the residue in the bag to the sample weight. Good dissolving reliability is achieved if, under these conditions, at least 80% by weight of the weighed-in amount of detergent is dissolved after 10 minutes.
Da bei der Verwendung dieser vorportionierten Waschmittel-Beutel keine Waschmittelaπteile ungelöst beziehungsweise undispergiert im Waschmaschinensumpf sich ablagern können, beträgt die Waschmit¬ teleinsparung durch bessere Ausnutzung des Waschmittels gegenüber der üblichen Verfahrensweise, bei der Waschmittel zu Beginn des Waschganges eingespült wird, etwa 20 bis 30 %. Andererseits lassen sich mit den erfindungsgemäßen Waschmittelerzeugnissen bei ge¬ wichtsgleicher Waschmitteldosierung bessere Waschergebnisse er¬ zielen als wenn das gleiche Waschmittel mit dem Waschwasser zu Beginn des Waschprozesses in die Waschmaschine eingespült wird. Das textile Flächengebilde kann in seiner Stabilität verbessert werden, indem man die Oberfläche durch thermische Verfestigung mechanisch stabilisiert, wodurch die zu seiner Herstellung ver¬ wendeten Fasern in ihrer Lage innerhalb des Flächengebildes fixiert werden.Since, when using these pre-portioned detergent sachets, no detergent portions can be deposited undissolved or undispersed in the washing machine sump, the savings in detergent due to better utilization of the detergent compared to the usual procedure in which detergent is rinsed in at the start of the wash cycle is approximately 20 to 30% . On the other hand, the detergent products according to the invention can achieve better washing results with the detergent dosage being of the same weight than if the same detergent is washed into the washing machine with the washing water at the start of the washing process. The stability of the textile fabric can be improved by mechanically stabilizing the surface by means of thermal consolidation, as a result of which the fibers used for its production are fixed in their position within the fabric.
Der Waschmittelbeutel kann eine oder auch mehrere Kammern ent¬ halten, wobei im Fall, daß der Beutel mehrere Kammern enthält, die Kammern unterschiedliche, miteinander nicht oder schlecht ver¬ trägliche Waschmittelbestandteile enthalten können. Wenn alle vier oder drei Kanten eines derartigen Beutels fest verschweißt sind, öffnet sich der Beutel beziehungsweise die Kammern beim Waschen nicht. Es ist aber möglich, eine oder auch mehrere Schweißnähte schwach auszuführen oder durch besondere Maßnahmen, beispielsweise durch Einlegen einer Trennschicht zu schwächen, so daß sich der Beutel oder die Kammer im Verlauf des Waschverfahrens öffnet und seinen Inhalt an die Waschflotte abgibt. Vorzugsweise ist der Beu¬ tel aber fest verschweißt und gibt seinen Inhalt nur durch die feinen Poren des Beutelmaterials frei.The detergent pouch can contain one or more compartments, and if the pouch contains several compartments, the compartments can contain different detergent components that are incompatible or poorly compatible with one another. If all four or three edges of such a bag are firmly welded, the bag or the chambers do not open during washing. But it is possible to make one or more welds weak or by special measures, for example weaken by inserting a separating layer so that the bag or chamber opens in the course of the washing process and releases its contents to the washing liquor. However, the bag is preferably welded firmly and only releases its contents through the fine pores of the bag material.
Der Beutel kann ein beliebiges teilcheπförmiges Waschmittel ent¬ halten. Die Korngrößenverte lung des Waschmittels kann im großen Bereich schwanken, beispielsweise im Bereich von 0,01 bis 3 Mil¬ limeter. Beim Einsatz von spezifisch schweren Waschmitteln liegt es nahe, entsprechend kleine Beutel zu verwenden. Andererseits aber darf die Beutelgröße eine bestimmte untere Größe nicht unter¬ schreiten, da sich der Beutel anderenfalls während des Waschvor¬ gangs aus den umzuwälzenden Textilien entfernen und sich in einem toten Winkel der Waschmaschine, beispielsweise an der Einfüllöff- nung, absetzen kann. Geeignete Beutel haben daher, wie oben be¬ reits angegeben, eine Mindest-Kantenlänge von etwa 5 Zentimeter und eine Oberflächengröße von 30 bis 300 QuadratZentimeter (ein¬ seitig gemessen). Vorzugsweise haben die Beutel an wenigstens einer Stelle eine Dicke von 10, insbesondere 15 Millimeter.The bag can contain any particulate detergent. The grain size distribution of the detergent can vary over a wide range, for example in the range from 0.01 to 3 millimeters. When using specifically heavy detergents, it makes sense to use correspondingly small bags. On the other hand, however, the bag size must not be less than a certain lower size, since otherwise the bag can remove itself from the textiles to be circulated during the washing process and settle in a blind spot of the washing machine, for example at the filler opening. Suitable bags therefore have, as already stated above, a minimum edge length of about 5 centimeters and a surface size of 30 to 300 square centimeters (measured on one side). The bags preferably have a thickness of 10, in particular 15, millimeters at at least one point.
Ein weiterer Gegenstand der vorliegenden Erfindung ist die Verwen¬ dung eines wie oben beschriebenen textilen Flächengebildes als Beutelmaterial für ein Waschmittelerzeugnis der genannten Art. Die Waschmittel enthaltenden Beutel können einzeln oder zu mehreren zusammenhängend hergestellt werden. Je nach Waschmittelbedarf kann der Verbraucher dann einen oder mehrere Beutel abtrennen und ver¬ wenden. Es ist auch möglich, anstelle von teilchenförm gen Wasch¬ mitteln pastenförmige in den Beuteln zu verpacken. In dem Fall ist es zweckmäßig, das Beutelmaterial auf der Innen- und/oder Außen¬ seite mit einem in Wasser löslichen oder eπtfernbaren Überzug abzudichten. Das beschriebene Waschmittelerzeugnis stellt eine bequeme und zu¬ verlässige Möglichkeit zur Waschmitteldosierung dar. An die Korn¬ größenverteilung, die Rieselfähigkeit und das Aussehen des so ver¬ packten teilchenförmigen Waschmittels werden im Vergleich zu nicht in Portionsbeuteln verpackten Waschmitteln nur geringe Anforderun¬ gen gestellt. Der Verbraucher kommt mit dem eigentlichen Wasch¬ mittel nicht in Berührung, was besonders wichtig für Verbraucher ist, die gegenüber Waschmittelbestandteilen allergisch reagieren. Da das Waschmittel nicht durch Absetzen im Laugensumpf der Wasch¬ maschine dem Waschprozeß entzogen werden kann, resultiert bei aus¬ gezeichnetem Waschergebnis eine markante Waschmitteleinsparung und eine dementsprechend verringerte Abwasserbelastung. Staubfeine Waschmittelanteile bleiben bis zum Gebrauch im Beutel eingeschlos¬ sen und grobe Waschmittelpartikel werden zuverlässig herausgelöst beziehungsweise herausgeschwemmt. Another object of the present invention is the use of a textile fabric as described above as bag material for a detergent product of the type mentioned. The detergent-containing bags can be produced individually or in a group. Depending on the detergent requirement, the consumer can then separate and use one or more bags. It is also possible to package paste-like detergents in the bags instead of particulate detergents. In this case, it is expedient to seal the bag material on the inside and / or outside with a coating that is soluble or removable in water. The detergent product described is a convenient and reliable possibility for metering detergent. Only small requirements are placed on the particle size distribution, the flowability and the appearance of the particulate detergent packaged in this way, compared to detergents not packaged in sachets. The consumer does not come into contact with the actual detergent, which is particularly important for consumers who are allergic to detergent components. Since the detergent cannot be removed from the washing process by settling in the suds of the washing machine, a marked saving in detergent results and a correspondingly reduced wastewater load when the washing result is excellent. Dust-fine detergent fractions remain enclosed in the bag until use and coarse detergent particles are reliably removed or washed out.

Mit je 140 Gramm Waschmittel (ohne Beutel = Versuch A; in zwei Beuteln = Versuch B) wurden Testtextilien mit künstlichen An¬ schmutzungen zusammen mit 3,5 Kilogramm sauberer Füllwäsche bei 60 °C im Einlaugenwaschverfahren gewaschen. Die Wasserhärte betrug 14 °d, die Wassermenge 21 Liter. Die Waschleistung wurde durch Remissionsmessung bei 460 Nanometer ermittelt. Man erhielt die in Tabelle 1 aufgeführten Ergebnisse: With 140 grams of detergent each (without bag = test A; in two bags = test B), test textiles with artificial soiling were washed together with 3.5 kg of clean laundry at 60 ° C. using the single-wash method. The water hardness was 14 ° d, the amount of water was 21 liters. The washing performance was determined by remission measurement at 460 nanometers. The results listed in Table 1 were obtained:
Tabel le 1Table 1
Bei allen Anschmutzungen ist ein deutlich besseres Waschergebnis erkennbar, wenn das Waschmittel in Beuteln aus Material mit genau abgestimmten Eigenschaften verwendet wird als wenn das Waschmittel mengengleich über die Einspülkammer der Waschmaschine zugegeben wird. With all soiling, a significantly better washing result can be seen if the detergent is used in bags made of material with precisely coordinated properties than if the detergent is added to the washing machine in the same quantity through the detergent dispenser.
