Description

Gebiet der Erfindungfield of invention

Die vorliegende Erfindung betrifft Vollwaschmitteltücher zur Reinigung von Textilien und insbesondere Vollwaschmitteltücher, bei denen das Substrat homogen verteilte waschaktive Komponenten enthält, sowie ein Verfahren zu deren Herstellung.The present invention relates to heavy-duty detergent wipes for cleaning textiles and in particular heavy-duty detergent wipes in which the substrate contains homogeneously distributed washing-active components, and to a process for their production.

Hintergrund der Erfindung und Stand der TechnikBackground of the invention and prior art

Seit Anbeginn der Menschheit besteht das Streben nach Hygiene. Schließlich stellt die Hygiene im Alltag der Menschen eine gewichtige Komponente dar. Der Hygienegedanke des Menschen besteht in erster Linie in der Erhaltung der Gesundheit. Mit der weiteren Entwicklung der Möglichkeiten gerieten neben den grundreinigenden Reinigungseffekten der Duft sowie die Verbesserung der Reinigungsleistungen durch die verwendeten Rohstoffmischungen in den Fokus. Die Optimierung der Reinigungsleistung kennzeichnet sich insbesondere durch die Möglichkeit der Verlängerung eines hygienisch reinen Zustandes sowie einer Verbesserung eines Reinigungsgrades.Hygiene has been a priority since the dawn of mankind. After all, hygiene is an important component in people's everyday lives. Human hygiene is primarily about maintaining health. With the further development of the possibilities, in addition to the basic cleaning effects, the scent and the improvement of the cleaning performance through the raw material mixtures used came into focus. The optimization of the cleaning performance is characterized in particular by the possibility of extending a hygienically clean state and improving the degree of cleaning.

Heutzutage kann die Hygiene in die Bereiche der Körper-, Oberflächen- und Textilhygiene unterteilt werden. Letztere wird differenziert in die Anwendung nach Material und Farbe des Textils. Spätestens in den 90'er Jahren des 20ten Jahrhunderts ist auch ökologische Reinigung in das Bewusstsein der Konsumenten getreten. Dabei ist es wünschenswert, einerseits die bereits erreichten Vorzüge eines Waschmittels zu erhalten und andererseits weitere innovative und ökologisch sinnvolle Produktlösungen zu erfinden.Nowadays, hygiene can be divided into the areas of body, surface and textile hygiene. The latter is differentiated in the application according to the material and color of the textile. By the 1990s at the latest, consumers became aware of ecological cleaning. It is desirable, on the one hand, to retain the advantages that a detergent has already achieved and, on the other hand, to invent further innovative and ecologically sensible product solutions.

Mit Beginn der industriellen Produktion von Waschmitteln wurden diese als Pulver realisiert. Ein Waschmittelpulver stellt noch heute eine Mischung aus unterschiedlichen waschaktiven Substanzen dar.With the beginning of the industrial production of detergents, these were realized as powders. A detergent powder is still a mixture of different washing-active substances.

Mit dem Fortschritt bei der Entwicklung von Waschmitteln fanden Enzyme und weitere neue tensidische Verbindungen ihren Einzug in dieses Marktsegment. Neben den zur Reinigung erforderlichen Substanzen werden heutzutage große Mengen an Füllstoff hinzugegeben. Dies führt dazu, dass eine Änderung im Dosierungsverhalten des Verbrauchers nicht erforderlich wurde. Erste Versuche, auf die Füllstoffe zu verzichten, führten zu einer Überdosierung der Tenside bedingt durch die gewohnte Anwendung seitens der Konsumenten.With progress in the development of detergents, enzymes and other new surfactant compounds found their way into this market segment. In addition to the substances required for cleaning, nowadays large amounts of filler are added. As a result, a change in the dosing behavior of the consumer was not required. Initial attempts to do without the fillers led to an overdose of surfactants due to the usual use by consumers.

Es folgte die Einführung der Flüssigwaschmittel, die rückstandsfreier zu dosieren sind und eine physikalische Alternative zu der Feststoffmischung des Waschmittels darstellen. Allerdings konnten die Flüssigwaschmittel in ihren reinigenden Eigenschaften bis heute nicht das Reinigungsniveau eines Vollwaschmittels (also einer Feststoffmischung) erreichen. Dies findet seine Begründung in der Limitierung eines Flüssigwaschmittels auf flüssige oder gut in Wasser lösliche Komponenten. Die entscheidende dabei fehlende Substanz in einem Flüssigwaschmittel stellt die Gruppe der Zeolithe dar. Diese unterstützen die Schmutzadsorption, sowie die Glanzbildung/Farbechtheit bei der Anwendung.This was followed by the introduction of liquid detergents, which can be dosed without leaving any residue and represent a physical alternative to the solid mixture of detergents. However, the cleaning properties of liquid detergents have not yet reached the cleaning level of heavy-duty detergents (i.e. a mixture of solids). The reason for this lies in the fact that a liquid detergent is limited to liquid components or components that are readily soluble in water. The decisive missing substance in a liquid detergent is the group of zeolites. These support the dirt adsorption as well as the gloss formation/color fastness during use.

Ein derzeitiger Produkttrend liegt in der Art und Weise der Portionierung des Waschmittels. Dies kann zum einen geschehen durch die Verpackung eines Flüssigwaschmittels in kleinen Polymerbeuteln. Eine andere physikalische Modifikation des Waschmittels besteht im Abmischen eines Waschmittels mit einem Fettalkohol, sodass gewünschte Formen erzielt werden können. Die DE 10 2010 060 126 A1 offenbart ein Zweiphasenprodukt in Form eines Waschmitteltuchs, das sich durch die Kombination eines hydrophilen Trägersubstrats mit einer flüssigen Tränklösung auszeichnet.A current product trend is the way the detergent is portioned. On the one hand, this can be done by packaging a liquid detergent in small polymer bags. Another physical modification of the detergent is blending a detergent with a fatty alcohol so that desired shapes can be achieved. The DE 10 2010 060 126 A1 discloses a two-phase product in the form of a laundry detergent wipe characterized by the combination of a hydrophilic carrier substrate and a liquid impregnating solution.

Die DE 10 2013 014 015 offenbart demgegenüber ein Dreiphasenprodukt, bei dem eine Dispersion auf ein bei Raumtemperatur festes Trägersubstrat appliziert wurde. Durch den erstmaligen Einsatz einer Dispersion konnte eine Reinigungsleistung mit den Merkmalen eines Waschmittelpulvers (z.B. Zeolithe, Schichtsilikate, etc.) realisiert werden. Hier wurden primär hydrophobe Trägersubstrate eingesetzt, da auch die Waschmitteldispersion auf Grund des höheren Anteils der waschaktiven Substanzen im Verhältnis zu dem Zweiphasensystem eine hydrophobe Eigenschaft aufweist. Die DE 10 2014 004 915 offenbart ein weiter verbessertes Dreiphasenprodukt mit homogenerer Verteilung der waschaktiven Substanzen sowie ein Verfahren zu dessen Herstellung.The DE 10 2013 014 015 in contrast, discloses a three-phase product in which a dispersion was applied to a carrier substrate that is solid at room temperature. By using a dispersion for the first time, it was possible to achieve a cleaning performance with the characteristics of a detergent powder (eg zeolites, phyllosilicates, etc.). Hydrophobic carrier substrates were primarily used here, since the detergent dispersion also has hydrophobic properties due to the higher proportion of washing-active substances in relation to the two-phase system. The DE 10 2014 004 915 discloses a further improved Three-phase product with a more homogeneous distribution of the washing-active substances and a process for its production.

Die EP 0 957 158 A1 offenbart einen Waschmittelartikel in Form eines starren Schicht-Produkts, das zwei wasserlösliche Substrate umfasst, die sandwich-artig auf beiden Seiten einer dünnen Schicht aus einer trockenen Waschmittel-Knete bzw. einem Pulver oder Granulat angeordnet sind, sodass das Produkt drei feste Phasen umfasst und somit vollständig trocken ist. Dieser trockene Waschmittelartikel löst sich bei seiner Verwendung vollständig auf.The EP 0 957 158 A1 discloses a detergent article in the form of a rigid sheet product comprising two water-soluble substrates sandwiched on either side of a thin layer of dry detergent putty, powder or granules, respectively, such that the product comprises three solid phases and is therefore completely dry. This dry detergent item completely dissolves with its use.

Die US 2003/207630 A1 offenbart ein Waschmittelprodukt, bei dem auf ein Substrat ein homogener Waschmittel-Brei aufgebracht wird, wonach der Wasseranteil des Breis verdampft wird, sodass das Endprodukt - wie der Waschmittelartikel gern, der EP 0 957 158 A1 - zwei feste Phasen umfasst und somit vollständig trocken ist.The U.S. 2003/207630 A1 discloses a detergent product in which a homogeneous detergent slurry is applied to a substrate, after which the water portion of the slurry is evaporated so that the final product - like the detergent article, the EP 0 957 158 A1 - comprises two solid phases and is therefore completely dry.

Die Aufgabe der vorliegenden Erfindung lag in der Bereitstellung eines Waschmitteltuchs mit homogener Verteilung der waschaktiven Substanzen bzw. festen Bestandteile der Dispersion auf dem Substrat sowie eines Verfahrens zu dessen Herstellung, um eine weiter verbesserte Verteilung der Aktivsubstanzen und damit eine bessere Leistung des Waschmitteltuchs zu erreichen.The object of the present invention was to provide a detergent cloth with homogeneous distribution of the washing-active substances or solid components of the dispersion on the substrate and a process for its production in order to achieve a further improved distribution of the active substances and thus better performance of the detergent cloth.

Zusammenfassung der ErfindungSummary of the Invention

Es ist ein Ziel der vorliegenden Erfindung, ein Dreiphasen-Waschmitteltuch vorzusehen, das eine gleichmässigere, insbesondere homogene, Verteilung der waschaktiven Substanzen bzw. festen Bestandteile der Dispersion auf dem Trägersubstrat aufweist. Es ist weiterhin ein Ziel der vorliegenden Erfindung, ein Verfahren zu dessen Herstellung anzugeben.It is an object of the present invention to provide a three-phase detergent sheet which has a more uniform, in particular homogeneous, distribution of the washing-active substances or solid components of the dispersion on the carrier substrate. It is also an object of the present invention to provide a method for its manufacture.

Dieses Ziel ist erreicht worden durch ein Verfahren zur Herstellung eines homogenen Dreiphasen-Waschmitteltuchs nach Anspruch 1.This object has been achieved by a process for the manufacture of a homogeneous three-phase detergent sheet according to claim 1.

Dieses Ziel ist auch erreicht worden durch ein Dreiphasen-Waschmitteltuch nach Anspruch 6.This aim has also been achieved by a three-phase detergent sheet according to claim 6.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Dreiphasen-Waschmitteltuchs und seines Herstellungsverfahrens ergeben sich aus den Unteransprüchen.Advantageous configurations of the three-phase detergent sheet according to the invention and its manufacturing process result from the dependent claims.

Beschreibung der bevorzugten AusführungsformenDescription of the Preferred Embodiments

Die Verteilung der waschaktiven Substanzen bzw. festen Bestandteile einer Dispersion auf einem Substrat ist in der Regel nicht homogen. Das erfindungsgemäße Dreiphasen-Waschmitteltuch mit homogener Verteilung der waschaktiven Substanzen bzw. festen Bestandteile auf einem Substrat konnte realisiert werden, indem die bei Raumtemperatur festen und wasserunlöslichen Sekundärbuilder (Zeolith und/oder Schichtsilikate und/oder optische Aufheller), die bisher Bestandteile der auf das Substrat aufgebrachten Dispersion waren, in das bei Raumtemperatur feste Substrat nun während seines Herstellungsprozesses - also vor dem Aufbringen eines flüssigen Tränkungsmediums - eingearbeitet werden. Die festen, wasserunlöslichen Additive können dabei im Rahmen eines Wasserbades vor der Verfestigung des Substrats hinzugegeben werden. Alternativ können das Zeolith und/oder die Schichtsilikate durch eine aufgeschlämmte Dispersion (Additiv/Wasser o.ä.) während der Herstellung des Substrats aufgesprüht werden.The distribution of the washing-active substances or solid components of a dispersion on a substrate is generally not homogeneous. The three-phase detergent sheet according to the invention with a homogeneous distribution of the washing-active substances or solid components on a substrate could be realized by the secondary builders (zeolite and/or phyllosilicates and/or optical brighteners) which are solid and water-insoluble at room temperature and previously contained on the substrate applied dispersion, are now incorporated into the substrate, which is solid at room temperature, during its manufacturing process - i.e. before the application of a liquid impregnation medium. The solid, water-insoluble additives can be added in a water bath before the substrate solidifies. Alternatively, the zeolite and/or the phyllosilicates can be sprayed on by means of a slurried dispersion (additive/water or the like) during production of the substrate.

Die Einarbeitung fester wasserunlöslicher und waschaktiver Substanzen (hier: Zeolith und/oder Schichtsilikat und/oder optische Aufheller) führt zu einer Aktivierung des Substrats mit Komponenten, die dem Dreiphasen-Endprodukt die Eigenschaften eines Vollwaschmittels verleihen. Nach der Einarbeitung der Feststoffe erfolgt die Tränkung des so funktionalisierten Substrats mit einem flüssigen Tränkungsmedium, bei dem es sich um ein Flüssigwaschmittel handelt. Die Tränkung des funktionalisierten Substrats mit der Flüssigwaschmittelformulierung kann durch Tränkung in einem Tauchbad, Aufsprühen des Flüssigwaschmittels auf das aktive Substrat oder Befeuchtung des Substrats mit dem Flüssigwaschmittel mittels einer oder mehrerer Befeuchtungsstangen erfolgen.The incorporation of solid, water-insoluble and washing-active substances (here: zeolite and/or sheet silicate and/or optical brighteners) leads to activation of the substrate with components that give the three-phase end product the properties of a heavy-duty detergent. After the solids have been incorporated, the substrate functionalized in this way is impregnated with a liquid impregnation medium, which is a liquid detergent. The functionalized substrate can be impregnated with the liquid detergent formulation by soaking in an immersion bath, spraying the liquid detergent onto the active substrate or moistening the substrate with the liquid detergent using one or more moistening sticks.

Das Verfahren, in das Substrat wasserunlösliche Feststoffe vor dem Aufbringen des Tränkungsmediums einzuarbeiten, hat folgende Vorteile:

  1. a) Verwendbarkeit größerer Partikel
  2. b) Verteilung des waschaktiven, wasserunlöslichen Feststoffs über die gesamte Substrattiefe (homogene Verteilung)
  3. c) Depotfunktion der im Substrat eingearbeiteten funktionellen Feststoffe, was den Effekt hat, dass die Diffusion der Partikel während des Waschprozesses länger dauert, sodass diese über einen längeren Zeitraum zur Verfügung stehen.
The process of incorporating water-insoluble solids into the substrate before applying the impregnation medium has the following advantages:
  1. a) Usability of larger particles
  2. b) Distribution of the washing-active, water-insoluble solid over the entire depth of the substrate (homogeneous distribution)
  3. c) Depot function of the functional solids incorporated in the substrate, which has the effect that the diffusion of the particles during the washing process takes longer, so that they are available over a longer period of time.

Als Substrat eignen sich Vliese aus Filamentfasern (Endlosfasern), insbesondere aus folgenden Materialien:

  • Polypropylen
  • Polyethylen
  • Viskose
  • Polyester
  • Polyamid,
  • sowie Mischungen dieser Rohstoffe
Nonwovens made of filament fibers (continuous fibers) are suitable as a substrate, in particular made of the following materials:
  • polypropylene
  • polyethylene
  • viscose
  • polyester
  • Polyamide,
  • and mixtures of these raw materials

Die aufgeführten Substratrohstoffe können Fasermischungen (einer oder mehrerer Filamentfasern), sowie Mischfasern (Mantel-Kern, oder Seite an Seite) sein. Die beschriebenen Komponenten sind hydrophob und verfügen daher über die weiterhin vorteilhafte Eigenschaft, hydrophobe Textilfarben im hydrophilen Waschwasser aufzunehmen.The substrate raw materials listed can be fiber mixtures (one or more filament fibers), as well as mixed fibers (sheath-core, or side by side). The components described are hydrophobic and therefore have the further advantageous property of absorbing hydrophobic textile dyes in the hydrophilic wash water.
