Definitions

  • the present invention relates to a pack or stack of impregnated wipe products and a method of making same.

Just like wet wipes, they offer the advantage of a convenient cleaning option that is basically available everywhere, be it for disinfecting surfaces or objects or for daily personal care, for example to remove make-up.
  • Both soaked pads and wet wipes are usually packaged in handy units of around 10 to 200 wipe products.
  • a disadvantage of this type of packaging is that an uneven distribution of the impregnating agent is often observed in the packaging. Because in the stack of soaked wipe products contained in the packaging, the soaking agent sinks due to gravity after a comparatively short standing time, so that the wipe products at the top of the stack no longer contain sufficient soaking agent, while the wipe products at the bottom of the stack contain an unnecessarily large amount of soaking agent or are surrounded by too much impregnating agent. This limits the usability and particularly the effectiveness of the wipes located at the top of the stack.

  • an attempt is also made to ensure the effectiveness of the tissue products located at the top of a stack by using a larger quantity of impregnating agent, in that these still have a sufficiently high moisture content even after the impregnating agent has dropped in the pack.
  • this has the consequence that the production of the wipe products becomes more expensive due to the increased need for impregnating agents and moreover, due to gravity, even more impregnating agent accumulates at the bottom of a package and generally remains unused there.

  • this solution fulfills the purpose of reducing the sagging behavior of the impregnating agent in a pack, it has the major disadvantage that the production of such fiber composite articles entails significantly increased effort and greatly increased costs.
  • the prior art does not provide a satisfactory and environmentally friendly solution that keeps the liquid gradient in a stack of saturated tissue products within an acceptable range and thereby increases the effectiveness of all saturated tissue products contained in the stack by a sufficient Guaranteed amount of impregnating agent contained in these while avoiding accumulation of liquid at the bottom of the pack.
  • the use of an increased amount of impregnating agent should be avoided and the solution should preferably be equally suitable for all known nonwoven materials, i.e. both for natural fibers and for synthetic fibers, and pollute the environment as little as possible.

Rather, the inventive use of biodegradable/compostable barriers in a package of tissue products has the added benefit environmentally friendly effect that due to the more even distribution of liquid in a pack of tissue products due to the at least one contained barrier layer, fewer and preferably no tissue products are contained in a pack that contain too few impregnating agents, i.e. are too dry for the desired application, and are therefore unused have to be disposed of.

Description

Die vorliegende Erfindung betrifft eine Packung oder einen Stapel mit getränkten Tuchprodukten sowie ein Verfahren zu deren Herstellung.The present invention relates to a pack or stack of impregnated wipe products and a method of making same.

Feuchttücher sind bekanntermaßen Vliesstoffe, die mit einer in der Regel flüssigen Zusammensetzung getränkt sind, die u.a. einen desinfizierenden, reinigenden und/oder pflegenden Inhaltsstoff enthält. Feuchttücher finden mittlerweile in vielen Bereichen der persönlichen Pflege und vor allem Babypflege Anwendung und erfreuen sich sehr hoher Beliebtheit, da sie die Möglichkeit einer schnellen und bequemen Reinigung bzw. Pflege bieten, ohne dass dafür zusätzliches Wasser erforderlich ist. Aber auch im Reinigungssektor, insbesondere zur Flächendesinfektion, werden Feuchttücher gern verwendet.As is known, wet wipes are non-woven fabrics that are impregnated with a composition, which is usually liquid and contains, among other things, a disinfecting, cleaning and/or care ingredient. Wet wipes are now used in many areas of personal care and especially baby care and are very popular because they offer the possibility of quick and convenient cleaning or care without the need for additional water. But wet wipes are also popular in the cleaning sector, especially for surface disinfection.

Auch getränkte Pads sind mit einer flüssigen Zusammensetzung getränkte Vliesstoffe, die sich von Feuchttüchern in der Regel nur durch ihr abweichendes Format und ggf. durch eine höhere Materialstärke des Vliesstoffs unterscheiden. Ebenso wie Feuchttücher bieten sie den Vorteil einer grundsätzlich überall verfügbaren bequemen Reinigungsmöglichkeit, sei es zur Desinfektion von Flächen oder Gegenständen oder zur täglichen persönlichen Pflege, beispielsweise zum Entfernen von Make-up.Impregnated pads are also nonwovens impregnated with a liquid composition, which as a rule differ from wet wipes only in their different format and possibly in a greater material thickness of the nonwoven. Just like wet wipes, they offer the advantage of a convenient cleaning option that is basically available everywhere, be it for disinfecting surfaces or objects or for daily personal care, for example to remove make-up.

Sowohl getränkte Pads als auch Feuchttücher sind in der Regel zu handlichen Einheiten von ca. 10 bis 200 Tuchprodukten verpackt. An dieser Art der Verpackung ist jedoch nachteilhaft, dass häufig eine ungleichmäßige Verteilung des Tränkungsmittels in der Verpackung beobachtet wird. Denn in dem in der Verpackung enthaltenen Stapel aus getränkten Tuchprodukten sinkt das Tränkungsmittel aufgrund der Schwerkraft bereits nach vergleichsweise kurzer Standzeit ab, sodass die oben in dem Stapel befindlichen Tuchprodukte nicht mehr ausreichend Tränkungsmittel enthalten, während die unten in dem Stapel befindlichen Tuchprodukte unnötig viel Tränkungsmittel enthalten bzw. von zu viel Tränkungsmittel umgeben sind. Hierdurch wird die Gebrauchstauglichkeit und insbesondere die Wirksamkeit der oben in dem Stapel befindlichen Tücher eingeschränkt. Eine Packung mit Tuchprodukten gemäß dem Oberbegriff des Anspruchs 1 ist z.B. aus EP-A-0978247 bekannt.Both soaked pads and wet wipes are usually packaged in handy units of around 10 to 200 wipe products. A disadvantage of this type of packaging, however, is that an uneven distribution of the impregnating agent is often observed in the packaging. Because in the stack of soaked wipe products contained in the packaging, the soaking agent sinks due to gravity after a comparatively short standing time, so that the wipe products at the top of the stack no longer contain sufficient soaking agent, while the wipe products at the bottom of the stack contain an unnecessarily large amount of soaking agent or are surrounded by too much impregnating agent. This limits the usability and particularly the effectiveness of the wipes located at the top of the stack. A pack of tissue products according to the preamble of claim 1 is, for example, from EP-A-0978247 known.

Zur Lösung dieses Problems sind aus dem Stand der Technik unterschiedliche Ansätze bekannt. Beispielsweise gibt es Halterungen bzw. Spender, in denen die Stapel mit den getränkten Tuchprodukten umgekehrt herum gelagert werden. Neben dem Nachteil der fehlenden Mobilität wird durch diesen Ansatz das Problem der ungleichmäßigen Verteilung von Tränkungsmittel innerhalb der Packung jedoch nicht gelöst, da auf diese Weise zwar die zuerst aus der Packung entnommenen Tuchprodukte ausreichend getränkt sind, während die in der Verpackung verbleibenden oberen Tuchprodukte eine zu geringe Menge an Tränkungsmittel enthalten. Das Problem wird daher nur insofern verlagert, dass nicht mehr die zuerst aus einer Packung entnommenen Tuchprodukte unzureichend getränkt sind, sondern die zuletzt entnommenen.Various approaches are known from the prior art for solving this problem. For example, there are holders or dispensers in which the stacks with the soaked wipe products are stored upside down. In addition to the disadvantage of the lack of mobility, this approach does not solve the problem of the uneven distribution of impregnating agent within the pack, since in this way the tissue products removed first from the pack are sufficiently saturated, while the upper tissue products remaining in the pack contain a small amount of impregnating agent. The problem is therefore only shifted to the extent that it is no longer the wipe products removed first from a pack that are insufficiently saturated, but the wipes removed last.

Ein alternativer Lösungsansatz sieht vor, ein Tränkungsmittel mit erhöhter Viskosität zu verwenden, um ein "Absacken" des Tränkungsmittels in der Packung zu verringern. Die erhöhte Viskosität wird dabei durch Verdicker erreicht. Auch dieser Ansatz ist mit verschiedenen Nachteilen behaftet, denn Verdicker beeinträchtigen die Wirksamkeit vieler Tränkungsmittel. Weiterhin bilden sich durch die erhöhte Viskosität des Tränkungsmittels Rückstände auf Oberflächen und es ist darüber hinaus eine größere Menge an Tränkungsmittel erforderlich, um eine zu reinigende Oberfläche ausreichend zu benetzen. Weiterhin wird auch versucht, durch eine größere Menge an verwendetem Tränkungsmittel auch die Wirksamkeit der oben in einem Stapel befindlichen Tuchprodukte zu gewährleisten, dadurch dass diese auch nach dem Absinken des Tränkungsmittels in der Packung noch eine ausreichend hohe Feuchte aufweisen. Dies hat allerdings zur Folge, dass die Herstellung der Tuchprodukte aufgrund des erhöhten Bedarfs an Tränkungsmittel teurer wird und sich überdies aufgrund der Schwerkraft noch mehr Tränkungsmittel am Boden einer Verpackung ansammelt und dort in der Regel ungenutzt verbleibt.An alternative approach is to use a higher viscosity saturant to reduce "sagging" of the saturant in the pack. The increased viscosity is achieved with thickeners. This approach also has various disadvantages, since thickeners impair the effectiveness of many impregnating agents. Furthermore, due to the increased viscosity of the impregnating agent, residues form on surfaces and, in addition, a larger amount of impregnating agent is required in order to adequately wet a surface to be cleaned. Furthermore, an attempt is also made to ensure the effectiveness of the tissue products located at the top of a stack by using a larger quantity of impregnating agent, in that these still have a sufficiently high moisture content even after the impregnating agent has dropped in the pack. However, this has the consequence that the production of the wipe products becomes more expensive due to the increased need for impregnating agents and moreover, due to gravity, even more impregnating agent accumulates at the bottom of a package and generally remains unused there.

Noch ein weiterer Ansatz zur besseren Verteilung von Tränkungsmittel in einem Stapel getränkter Tuchprodukte sieht vor, dass als zu tränkende Vliesmaterialien nur noch Naturfasern (Viskose, Tencel o.ä.) verwendet werden, da diese eine höhere Saugfähigkeit als synthetische Fasern aufweisen. Dies führt einerseits zu einer erhöhten erforderlichen Tränkmenge, was wiederum erhöhte Herstellungskosten mit sich bringt, und andererseits zu möglichen Wechselwirkungen mit in dem Tränkungsmittel enthaltenen Wirkstoffen (hier sei als Beispiel erwähnt, dass die Wiederfindungsrate von Benzalkoniumchlorid auf Viskose im Vergleich zu PET sehr schlecht ist).Yet another approach to better distribution of impregnating agent in a stack of impregnated cloth products provides that only natural fibers (viscose, tencel or the like) are used as nonwoven materials to be impregnated, since these have a higher absorbency than synthetic fibers. On the one hand, this leads to an increased amount of impregnation required, which in turn entails increased production costs, and on the other hand to possible interactions with the active ingredients contained in the impregnation agent (here it should be mentioned as an example that the recovery rate of benzalkonium chloride on viscose is very poor compared to PET) .

Die EP 0 978 247 A1 beschreibt einen Stapel mit getränkten Tüchern, der eine oder mehrere Verdunstungsschutzlagen zwischen den getränkten Tüchern enthält, durch welche die Verdunstung flüchtiger Bestandteile des Tränkungsmittels verhindert werden soll. Die Verdunstungsschutzlagen sind jedoch nicht notwendigerweise flüssigkeitsundurchlässig. Vorzugsweise sind die Verdunstungsschutzlagen hydrophob und bestehen aus Polyethylen oder Polypropylen. Dies stellt jedoch eine zusätzliche Belastung für die Umwelt dar, da diese Materialien nicht biologisch abbaubar sind, aber in jeder Packung mehrfach als zu entsorgender Abfall anfallen.the EP 0 978 247 A1 describes a stack of impregnated wipes that includes one or more anti-evaporation layers between the impregnated wipes to prevent evaporation of volatile components of the impregnant. However, the evaporation control layers are not necessarily liquid-impermeable. The evaporation protection layers are preferably hydrophobic and consist of polyethylene or polypropylene. However, this places an additional burden on the environment, as these materials are not biodegradable, but accumulate multiple times in each pack as waste for disposal.

Die DE 10 2006 035 570 A1 beschreibt eine Packung mit scheiben- bzw. padförmigen Faserverbundartikeln, die jeweils eine mit einer Tränkflüssigkeit getränkte Faservlieslage und eine flüssigkeitsundurchlässige Folienlage umfassen, die eine Flüssigkeitsmigration zum Boden sowie eine Verdunstung verhindert und dem Artikel Formstabilität verleiht. Diese Lösung erfüllt zwar den Zweck der Reduzierung des Absackverhaltens des Tränkungsmittels in einer Packung, hat jedoch den großen Nachteil, dass die Herstellung solcher Faserverbundartikel einen deutlich erhöhten Aufwand und stark erhöhte Kosten mit sich bringt.the DE 10 2006 035 570 A1 describes a pack with disk- or pad-shaped fiber composite articles, each comprising a fiber fleece layer soaked with an impregnating liquid and a liquid-impermeable film layer, which prevents liquid migration to the bottom and evaporation and gives the article dimensional stability. Although this solution fulfills the purpose of reducing the sagging behavior of the impregnating agent in a pack, it has the major disadvantage that the production of such fiber composite articles entails significantly increased effort and greatly increased costs.

Zusammenfassend bleibt festzuhalten, dass aus dem Stand der Technik keine zufriedenstellende und die Umwelt nicht belastende Lösung bekannt ist, die den Flüssigkeitsgradienten in zu einem Stapel verpackter getränkter Tuchprodukte in einem akzeptablen Rahmen hält und dadurch die Wirksamkeit aller in dem Stapel enthaltener getränkter Tuchprodukte durch eine ausreichende Menge an in diesen enthaltenem Tränkungsmittel bei gleichzeitiger Vermeidung von Flüssigkeitsansammlungen am Boden der Packung gewährleistet.In summary, it can be said that the prior art does not provide a satisfactory and environmentally friendly solution that keeps the liquid gradient in a stack of saturated tissue products within an acceptable range and thereby increases the effectiveness of all saturated tissue products contained in the stack by a sufficient Guaranteed amount of impregnating agent contained in these while avoiding accumulation of liquid at the bottom of the pack.

Es ist die Aufgabe der vorliegenden Erfindung, eine alternative Lösung für eine Packung, die einen Stapel mit getränkten Tuchprodukten enthält, bereitzustellen, die die o.g. aus dem Stand der Technik bekannten Nachteile vermeidet und sich insbesondere dadurch auszeichnet, dass der Flüssigkeitsgradient in der Packung bzw. in dem Stapel getränkter Tuchprodukte geringgehalten wird. Dabei soll insbesondere auf die Verwendung einer erhöhten Menge an Tränkungsmittel verzichtet werden und die Lösung soll sich vorzugsweise gleichermaßen für alle bekannten Vliesmaterialen, d.h. sowohl für Naturfasern als auch für synthetische Fasern eignen, und die Umwelt möglichst wenig belasten.It is the object of the present invention to provide an alternative solution for a pack containing a stack of soaked tissue products, which avoids the above-mentioned disadvantages known from the prior art and is characterized in particular by the fact that the liquid gradient in the pack or in the stack of soaked wipe products is kept low. In particular, the use of an increased amount of impregnating agent should be avoided and the solution should preferably be equally suitable for all known nonwoven materials, i.e. both for natural fibers and for synthetic fibers, and pollute the environment as little as possible.

Allgemeine Beschreibung der ErfindungGeneral Description of the Invention

Die Erfindung löst diese Aufgabe mit den Merkmalen der Ansprüche und insbesondere durch Bereitstellen eines Stapels mit Tuchprodukten bzw. einer Packung mit Tuchprodukten (sog. "Flowpack") enthaltend einen Stapel, der eine Vielzahl von aufeinander angeordneten Tuchprodukten umfasst, wobei die Tuchprodukte jeweils einen mit einem Tränkungsmittel getränkten Vliesstoff umfassen, und wobei in dem Stapel, der die aufeinander angeordneten Tuchprodukte umfasst, auch zumindest eine Sperrschicht angeordnet ist, die ein Material umfasst oder aus einem Material besteht, das eine andere Saugfähigkeit für das Tränkungsmittel aufweist als der Vliesstoff, den die Tuchprodukte umfassen, und wobei das Material, das die zumindest eine Sperrschicht umfasst oder aus dem diese besteht, eine flüssigkeitsundurchlässige Folie ist, die aus biologisch abbaubarem und/oder kompostierbarem Kunststoff besteht.The invention solves this problem with the features of the claims and in particular by providing a stack of tissue products or a pack of tissue products (so-called. "Flowpack") containing a stack comprising a plurality of tissue products arranged one on top of the other, the tissue products each having a nonwoven fabric impregnated with an impregnating agent, and wherein in the stack comprising the towel products arranged on top of one another there is also arranged at least one barrier layer which comprises or consists of a material which has a different absorbency for the impregnating agent than the nonwoven fabric which the Wipe products include and wherein the material comprising or comprising the at least one barrier layer is a liquid impervious film comprised of biodegradable and/or compostable plastic.

Unter einem Tuchprodukt wird für die Zwecke der Erfindung insbesondere ein Pad oder ein Tuch aus Vliesmaterial verstanden, das mit einer flüssigen Zusammensetzung getränkt werden kann.For the purposes of the invention, a towel product is understood to mean, in particular, a pad or a towel made of nonwoven material that can be impregnated with a liquid composition.

Wie herkömmliche Tuchprodukte sind auch die erfindungsgemäß gestapelten getränkten Tuchprodukte aufeinander angeordnet und optional gefaltet, beispielsweise indem eine Lage Tuchprodukt jeweils in die darüberliegende und die darunterliegende Lage Tuchprodukt eingreift. Anders als herkömmliche Tuchprodukte enthält der erfindungsgemäße Stapel an Tuchprodukten jedoch zumindest eine Sperrschicht mit oder aus einem Material, das eine andere Saugfähigkeit aufweist als der Vliesstoff, den die Tuchprodukte umfassen. Die Sperrschicht verhindert dabei, dass Tränkflüssigkeit sich aufgrund der Schwerkraft am Boden der Packung bzw. des Stapels ansammelt, da sie undurchlässig oder im Wesentlichen undurchlässig für Flüssigkeiten ist.Like conventional tissue products, the saturated tissue products stacked in accordance with the present invention are stacked one on top of the other and optionally folded, for example by having one layer of tissue product interlock with the layer of tissue product above and the layer of tissue product below. However, unlike conventional wipe products, the stack of wipe products of the present invention includes at least one barrier layer comprising or made of a material that has a different absorbency than the nonwoven fabric comprising the wipe products. The barrier layer prevents the impregnating liquid from spilling due to gravity Bottom of the pack or stack accumulates because it is impermeable or substantially impermeable to liquids.

Die Anzahl der für eine Packung Tuchprodukte vorgesehenen Sperrschichten und deren Positionierung innerhalb des Stapels der Tuchprodukte ist frei wählbar und sollte insbesondere von der Anzahl der in dem Stapel enthaltenen Tuchprodukte abhängig gemacht werden. In kleinen Stapeln von beispielsweise 10 Tuchprodukten kann eine Sperrschicht ausreichend sein, die zwischen jeweils 5 der Tuchprodukte angeordnet ist. Auf diese Weise bildet sich zwar oberhalb und unterhalb der Sperrschicht in den im Stapel enthaltenen Tuchprodukten ein Flüssigkeitsgradient, der jedoch dadurch, dass die Sperrschicht undurchlässig für das Tränkungsmittel ist, deutlich geringer ist als der Flüssigkeitsgradient in einer entsprechenden Stapelung Tuchprodukte ohne dazwischen angeordnete Sperrschicht.The number of barrier layers provided for a pack of tissue products and their positioning within the stack of tissue products is arbitrary and should be made dependent in particular on the number of tissue products contained in the stack. In small stacks of, for example, 10 tissue products, a barrier placed between every 5 of the tissue products may be sufficient. In this way, a liquid gradient forms above and below the barrier layer in the tissue products contained in the stack, but because the barrier layer is impermeable to the impregnating agent, this gradient is significantly lower than the liquid gradient in a corresponding stack of tissue products without a barrier layer arranged in between.

In größeren Verpackungseinheiten, beispielsweise in Packungen, die jeweils 50, 100 oder 200 Tuchprodukte enthalten, bietet sich die Anordnung mehrerer Sperrschichten innerhalb des Stapels an Tuchprodukten an, beispielsweise jeweils in einem Abstand von 5, 10, 20 oder 50 Tuchprodukten.In larger packaging units, for example in packs each containing 50, 100 or 200 tissue products, it is possible to arrange several barrier layers within the stack of tissue products, for example at a distance of 5, 10, 20 or 50 tissue products.

Erfindungsgemäß weist das Material, das die zumindest eine Sperrschicht umfasst oder aus dem diese besteht, eine geringere Saugfähigkeit auf als der Vliesstoff, den die Tuchprodukte umfassen, wobei die Sperrschicht undurchlässig oder im Wesentlichen undurchlässig für Flüssigkeiten ist.In accordance with the present invention, the material comprising or comprising the at least one barrier layer has a lower absorbency than the nonwoven fabric comprising the wipe products, the barrier layer being impermeable or substantially impermeable to liquids.

Das flüssigkeitsundurchlässige Material, das die zumindest eine Sperrschicht umfasst oder aus dem diese besteht, ist dabei erfindungsgemäß eine Folie, die aus biologisch abbaubarem und/oder kompostierbarem Kunststoff besteht. Insbesondere ist der biologisch abbaubare und/oder kompostierbare Kunststoff dabei aus der Gruppe ausgewählt, die aus thermoplastischer Stärke, Cellulose, abbaubaren Polyestern, Polylactid, Seealgen, Chitin, Chitosan, Lignin oder Mischungen dieser besteht oder eines oder mehrere der vorgenannten Materialien umfasst. Da eine Sperrschicht je nach Größe der Packung an Tuchprodukten bzw. je nach Menge der in einer Packung enthaltenen Tuchprodukte pro Packung mehrfach enthalten sein kann, entsteht bei jeder Packung durch die enthaltenen Sperrschichten ein erhöhter Abfall, der jedoch aufgrund der biologischen Abbaubarkeit bzw. Kompostierbarkeit der flüssigkeitsundurchlässigen Folie keine zusätzliche Belastung für die Umwelt darstellt. Vielmehr hat die erfindungsgemäße Verwendung biologisch abbaubarer bzw. kompostierbarer Sperrschichten in einer Packung mit Tuchprodukten den zusätzlichen umweltschonenden Effekt, dass durch die aufgrund der zumindest einen enthaltenen Sperrschicht gleichmäßigere Verteilung von Flüssigkeit in einer Packung Tuchprodukte weniger und bevorzugt gar keine Tuchprodukte in einer Packung enthalten sind, die zu wenig Tränkungsmittel enthalten, also für die gewünschte Anwendung zu trocken sind, und daher ungenutzt entsorgt werden müssen.According to the invention, the liquid-impermeable material that comprises the at least one barrier layer or from which it consists is a film that consists of biodegradable and/or compostable plastic. In particular, the biodegradable and/or compostable plastic is selected from the group consisting of thermoplastic starch, cellulose, degradable polyesters, polylactide, seaweed, chitin, chitosan, lignin or mixtures of these or one or more of the aforementioned materials. Since a barrier layer can be contained several times per pack, depending on the size of the pack of tissue products or depending on the quantity of tissue products contained in a pack, the barrier layers contained in each pack result in increased waste, which, however, is due to the biodegradability or compostability of the liquid-impermeable film does not represent any additional burden on the environment. Rather, the inventive use of biodegradable/compostable barriers in a package of tissue products has the added benefit environmentally friendly effect that due to the more even distribution of liquid in a pack of tissue products due to the at least one contained barrier layer, fewer and preferably no tissue products are contained in a pack that contain too few impregnating agents, i.e. are too dry for the desired application, and are therefore unused have to be disposed of.

Der in einer erfindungsgemäßen Packung Tuchprodukte enthaltene Stapel umfasst mehrere übereinander angeordnete Lagen Tuchprodukte, die durch eine Sperrschicht von mehreren weiteren übereinander angeordneten Lagen Tuchprodukte getrennt sind.The stack contained in a package of tissue products according to the present invention comprises a plurality of superimposed layers of tissue products separated by a barrier layer from a plurality of further superimposed layers of tissue products.

Da in größeren Verpackungseinheiten mehrere Sperrschichten erforderlich bzw. ratsam sind, umfasst der in einer größeren Packung Tuchprodukte enthaltene Stapel vorzugsweise mehrere Sperrschichten, die voneinander durch eine oder mehrere aufeinander angeordnete Lagen Tuchprodukte beabstandet sind.Since multiple barrier layers are required or advisable in larger packaging units, the stack contained in a larger package of tissue products preferably comprises multiple barrier layers spaced apart from one another by one or more stacked layers of tissue products.

Gemäß einer Ausführungsform enthält eine erfindungsgemäße Packung mit Tuchprodukten einen Stapel, in dem getränkte Tuchprodukte alternierend mit Sperrschichten aufeinander angeordnet sind, d.h. auf jeder Lage Tuchprodukt ist eine Lage Sperrschicht angeordnet, auf der wiederum eine Lage Tuchprodukt angeordnet ist. Auf diese Weise verbleibt immer die exakt gewünschte Menge an Tränkungsmittel in dem Tuchprodukt, da jedes Tuchprodukt sowohl nach oben als auch nach unten durch eine Lage flüssigkeitsundurchlässige Sperrschicht begrenzt ist.According to one embodiment, a package of tissue products according to the invention comprises a stack in which impregnated tissue products are arranged alternately with barrier layers on top of one another, i.e. on each layer of tissue product there is a layer of barrier layer on which in turn is arranged a layer of tissue product. In this way, the exact desired amount of saturant will always remain in the wipe product, since each wipe product is bounded both at the top and at the bottom by a layer of liquid-impermeable barrier.

Gemäß einer weiteren Ausführungsform enthält eine erfindungsgemäße Packung mit Tuchprodukten einen Stapel, in dem jeweils mehrere aufeinander angeordnete Lagen Tuchprodukt, beispielsweise 2-20 Lagen Tuchprodukt, bevorzugter 3 bis 15 Lagen Tuchprodukt und besonders bevorzugt 5 bis 10 Lagen Tuchprodukt durch eine Lage Sperrschicht von wiederum mehreren aufeinander angeordnete Lagen Tuchprodukt, beispielsweise 2-20 Lagen Tuchprodukt, bevorzugter 3 bis 15 Lagen Tuchprodukt und besonders bevorzugt 5 bis 10 Lagen Tuchprodukt, getrennt sind. Auf diese Weise befinden sich jeweils 2-20 Lagen Tuchprodukt, bevorzugter 3 bis 15 Lagen Tuchprodukt und besonders bevorzugt 5 bis 10 Lagen Tuchprodukt zwischen zwei Sperrschichten, wobei das Tränkungsmittel aufgrund der Schwerkraft immer nur zwischen zwei Sperrschichten nach unten fließen kann, jedoch nicht in die unterhalb der begrenzenden Sperrschicht angeordneten Tuchprodukte oder sogar bis an den Boden der Packung gelangen kann. Der Flüssigkeitsgradient in der Packung wird auf diese Weise geringgehalten und ist natürlich umso kleiner, je weniger Lagen Tuchprodukte zwischen zwei Sperrschichten angeordnet sind. Durch die Wahl einer geeigneten Menge an pro Stapel verwendeter Sperrschichten sowie durch deren geeignete Positionierung, insbesondere in einem gleichbleibenden Abstand von wenigen Lagen Tuchprodukte, wird gewährleistet, dass jedes in dem Stapel enthaltene getränkte Tuchprodukt eine ausreichende Menge an Tränkungsmittel enthält, sodass die getränkten Tuchprodukte, unabhängig davon, ob sie oben oder unten in dem Stapel angeordnet sind, zuverlässig den gewünschten Reinigungserfolg bieten können.According to a further embodiment, a pack of tissue products according to the invention contains a stack in which a plurality of layers of tissue product arranged one on top of the other, for example 2-20 layers of tissue product, more preferably 3 to 15 layers of tissue product and particularly preferably 5 to 10 layers of tissue product, are separated by a barrier layer of several layers superposed plies of tissue product, for example 2-20 plies of tissue product, more preferably 3 to 15 plies of tissue product and most preferably 5 to 10 plies of tissue product. In this way there are always 2-20 plies of tissue product, more preferably 3 to 15 plies of tissue product and most preferably 5 to 10 plies of tissue product between two barrier layers, whereby the impregnant can only ever flow down between two barrier layers due to gravity, but not into the tissue products placed beneath the constraining barrier or even to the bottom of the package. The liquid gradient in the pack is kept small in this way and is of course the smaller the fewer layers of tissue products placed between two barrier layers are. By choosing an appropriate amount of barrier layers used per stack and by positioning them appropriately, particularly at a consistent spacing of a few layers of wipe products, it is ensured that each impregnated wipe product contained in the stack contains a sufficient amount of impregnating agent such that the impregnated wipe products, regardless of whether they are arranged at the top or bottom of the stack, can reliably provide the desired cleaning success.

Die vorliegende Erfindung eignet sich uneingeschränkt für alle Vliesstoffe. Daher kann der Vliesstoff, der in einem erfindungsgemäßen Stapel an getränkten Tuchprodukten bzw. in einer erfindungsgemäßen Packung mit getränkten Tuchprodukten enthalten ist, ein herkömmlicher Vliesstoff sein, insbesondere ein Vliesstoff, der Viskosefasern, Polypropylenfasern, Lyocell-Fasern, PET-Fasern, Mikrofasern, Baumwoll-Fasern oder Mischungen dieser umfasst oder daraus besteht.The present invention is fully suitable for all nonwovens. Therefore, the nonwoven fabric contained in a stack of impregnated tissue products or in a pack of impregnated tissue products according to the invention can be a conventional nonwoven fabric, in particular a nonwoven fabric comprising viscose fibers, polypropylene fibers, lyocell fibers, PET fibers, microfibers, cotton - comprises or consists of fibers or mixtures thereof.

Gemäß einer Ausführungsform besteht der Vliesstoff, der in einem erfindungsgemäßen Stapel an getränkten Tuchprodukten bzw. in einer erfindungsgemäßen Packung mit getränkten Tuchprodukten enthalten ist, aus Viskosefasern und/oder Lyocell-Fasern und/oder PET-Fasern, d.h. er kann entweder zu 100 % aus Viskosefasern, Lyocell-Fasern oder PET-Fasern bestehen, oder aus Mischfasern dieser bestehen.According to one embodiment, the nonwoven fabric contained in a stack of impregnated tissue products or in a pack of impregnated tissue products according to the invention consists of viscose fibers and/or lyocell fibers and/or PET fibers, i.e. it can be either 100% Viscose fibers, lyocell fibers or PET fibers consist, or consist of mixed fibers of these.

Optional enthält der Vliesstoff auch Mikrofasern und/oder Baumwoll-Fasern, beispielsweise zu einem Anteil von jeweils bis zu 20 Gew.-%, insbesondere von 0,1 - 5,0 Gew.-%.Optionally, the non-woven fabric also contains microfibers and/or cotton fibers, for example in a proportion of up to 20% by weight, in particular 0.1-5.0% by weight.

Gemäß einer bevorzugten Ausführungsform besteht der Vliesstoff, der in einem erfindungsgemäßen Stapel an getränkten Tuchprodukten bzw. in einer erfindungsgemäßen Packung mit getränkten Tuchprodukten enthalten ist, aus Viskosefasern und/oder Lyocell-Fasern und/oder PET-Fasern und/oder Hanffasern und/oder Cellulosefasern und/oder Flachsfasern, sowie optional zusätzlich aus 0,1 - 20,0 Gew.-% Mikrofasern und/oder 0,1 - 20,0 Gew.-% Baumwoll-Fasern.According to a preferred embodiment, the nonwoven fabric contained in a stack of impregnated tissue products or in a pack of impregnated tissue products according to the invention consists of viscose fibers and/or lyocell fibers and/or PET fibers and/or hemp fibers and/or cellulosic fibers and/or flax fibers, and optionally additionally of 0.1-20.0% by weight of microfibers and/or 0.1-20.0% by weight of cotton fibers.

Besonders bevorzugt umfasst oder besteht der Vliesstoff, der in einem erfindungsgemäßen Stapel an getränkten Tuchprodukten bzw. in einer erfindungsgemäßen Packung mit getränkten Tuchprodukten enthalten ist, aus 30 - 70 Gew.-% Viskosefasern und 30 - 70 Gew.-% PET-Fasern sowie optional 0,1 - 5,0 Gew.-% Mikrofasern und/oder 0,1 - 30,0 Gew.- % Baumwoll-Fasern.Particularly preferably, the nonwoven fabric contained in a stack of impregnated tissue products or in a pack of impregnated tissue products according to the invention comprises or consists of 30-70% by weight viscose fibers and 30-70% by weight PET fibers and optionally 0.1 - 5.0% by weight microfibers and/or 0.1 - 30.0% by weight cotton fibers.

In Ausführungsformen, in denen der Vliesstoff weder Lyocell-Fasern, noch Mikrofasern oder Baumwoll-Fasern enthält, sondern ausschließlich aus Viskosefasern und PET-Fasern besteht, kann der Anteil von Viskosefasern zu PET-Fasern stufenlos variieren, beispielsweise von 1 Gew.-% Viskosefasern / 99 Gew.-% PET-Fasern zu 99 Gew.-% Viskosefasern / 1 Gew.-% PET-Fasern.In embodiments in which the nonwoven contains neither Lyocell fibers nor microfibers or cotton fibers but consists exclusively of viscose fibers and PET fibers, the proportion of viscose fibers to PET fibers can vary continuously, for example from 1% by weight viscose fibers / 99% by weight PET fibers to 99% by weight viscose fibers / 1% by weight PET fibers.

Die in einem erfindungsgemäßen Stapel oder einer erfindungsgemäßen Packung enthaltenen getränkten Tuchprodukte können mit einem beliebigen Tränkungsmittel getränkt sein, wobei das Tränkungsmittel insbesondere eine Zusammensetzung auf Wasser-, Öl- oder Alkoholbasis, eine Öl-in-Wasser-Emulsion oder eine Wasser-in-ÖI-Emulsion sein kann und/oder insbesondere aus der Gruppe ausgewählt ist, die kosmetische Zusammensetzungen oder Zubereitungen, Reinigungsmittel und Desinfektionsmittel umfasst oder daraus besteht.The impregnated wipe products contained in a stack or packet according to the invention may be impregnated with any impregnating agent, in particular the impregnating agent being a water-, oil- or alcohol-based composition, an oil-in-water emulsion or a water-in-oil - Emulsion can be and / or is selected in particular from the group that includes or consists of cosmetic compositions or preparations, cleaning agents and disinfectants.

Unter kosmetischen Zusammensetzungen oder Zubereitungen werden alle Arten von flüssigen kosmetischen Zusammensetzungen oder Zubereitungen verstanden, einschließlich Mittel zur Gesichts- und/oder Körperreinigung und -pflege, De-Makeup, Gesichtsmasken, Kuren, Hautpflegemittel, kosmetische Mittel sowie Mittel, die einen medizinischen oder kosmetischen Wirkstoff enthalten, wobei der Wirkstoff z.B. eine Verbindung mit pflegenden, fettenden, rückfettenden, beruhigenden, feuchtigkeitsspendenden, entzündungshemmenden, regenerativ wirkenden, wundheilungsfördernden, belebenden, straffenden, durchblutungsfördernden, antimikrobiellen, fungiziden, bakteriziden, antiallergischen und/oder antibakteriellen Eigenschaften sein kann.Cosmetic compositions or preparations are understood to mean all types of liquid cosmetic compositions or preparations, including facial and/or body cleansing and care products, de-makeup, face masks, cures, skin care products, cosmetic products and products containing a medicinal or cosmetic active ingredient contain, where the active ingredient e.g. a compound with caring, greasing, moisturizing, calming, moisturizing, anti-inflammatory, regenerative, wound healing, invigorating, firming, blood circulation-promoting, antimicrobial, fungicidal, bactericidal, antiallergic and/or antibacterial properties.

Unter Reinigungsmitteln werden sowohl Mittel zur Körperreinigung als auch Mittel zur Reinigung von Oberflächen, z.B. Böden, verstanden.Cleaning agents are understood to mean both agents for cleaning the body and agents for cleaning surfaces, e.g. floors.

Unter Desinfektionsmitteln werden sowohl Hautdesinfektionsmittel, insbesondere Handdesinfektionsmittel, als auch Flächendesinfektionsmittel verstanden.Disinfectants are understood to mean both skin disinfectants, in particular hand disinfectants, and surface disinfectants.

Damit die in der erfindungsgemäßen Packung mit Tuchprodukten ebenfalls enthaltene zumindest eine Sperrschicht nicht von den Anwendern versehentlich wie ein getränktes Tuchprodukt zur Reinigung etc. verwendet wird, unterscheidet sich die zumindest eine Sperrschicht optional optisch von den Tuchprodukten, insbesondere durch eine abweichende Farbe.So that the at least one barrier layer also contained in the pack with tissue products according to the invention is not accidentally used by the users like a soaked tissue product for cleaning etc., the at least one barrier layer optionally differs optically from the tissue products, in particular by a different color.

Die Erfindung betrifft weiterhin auch ein Verfahren zum Herstellen einer Packung mit Tuchprodukten enthaltend einen Stapel, der eine Vielzahl von aufeinander angeordneten Tuchprodukten umfasst, die jeweils einen mit einem Tränkungsmittel getränkten Vliesstoff umfassen, wobei in dem Stapel, der die aufeinander angeordneten Tuchprodukte umfasst, auch zumindest eine Sperrschicht angeordnet wird, die ein Material umfasst oder aus einem Material besteht, das eine andere Saugfähigkeit aufweist als der Vliesstoff, den die Tuchprodukte umfassen, wobei die zumindest eine Sperrschicht eine flüssigkeitsundurchlässige Folie ist, die aus biologisch abbaubarem und/oder kompostierbarem Kunststoff besteht.The invention also relates to a method for producing a pack of tissue products containing a stack comprising a plurality of tissue products arranged one on top of the other, each comprising a nonwoven fabric impregnated with an impregnating agent, wherein in the stack comprising the tissue products arranged one on top of the other also at least disposing a barrier layer comprising or consisting of a material having a different absorbency than the non-woven fabric comprising the towel products, the at least one barrier layer being a liquid-impermeable film composed of biodegradable and/or compostable plastic.

Vorzugsweise werden in dem erfindungsgemäßen Verfahren zwischen jeweils zwei Sperrschichten mehrere aufeinander angeordnete Lagen Tuchprodukte angeordnet, wobei die Sperrschichten und die Tuchprodukte zusammen den Stapel bilden. Insbesondere können zwischen zwei Lagen Sperrschicht dabei beispielsweise 2 bis 20 Lagen Tuchprodukte, insbesondere 3 bis 15 Lagen Tuchprodukte und besonders bevorzugt 5 bis 10 Lagen Tuchprodukte angeordnet werden.In the method according to the invention, a plurality of layers of tissue products arranged one on top of the other are preferably arranged between two barrier layers in each case, with the barrier layers and the tissue products together forming the stack. In particular, for example 2 to 20 layers of cloth products, in particular 3 to 15 layers of cloth products and particularly preferably 5 to 10 layers of cloth products can be arranged between two layers of barrier layer.

Die in dem erfindungsgemäßen Verfahren eingesetzten Tuchprodukte, Vliesstoffe, Tränkungsmittel und Sperrschichten können insbesondere so beschaffen sein wie voranstehend mit Bezug auf die erfindungsgemäße Packung mit Tuchprodukten bzw. den Stapel mit Tuchprodukten beschrieben.The tissue products, nonwoven fabrics, impregnating agents and barrier layers used in the method according to the invention can in particular be of the type described above with reference to the pack of tissue products or the stack of tissue products according to the invention.

Die großtechnische Produktion kann vorteilhafterweise dadurch, dass für die Anordnung einer Sperrschicht in dem Stapel lediglich die für die Tuchprodukte verwendete Vliesrolle durch eine Rolle mit dem Sperrschichtmaterial substituiert werden muss, unverändert fortgeführt werden, d.h. es sind keine anderen oder zusätzlichen Maschinen erforderlich.Advantageously, large-scale production can be continued unaltered, i.e., no other or additional machinery is required, because the placement of a barrier layer in the stack merely requires substituting a roll of the barrier material for the roll of non-woven fabric used for the towel products.

Genaue Beschreibung der ErfindungDetailed description of the invention

Die Erfindung wird nun genauer anhand eines Ausführungsbeispiels und mit Bezug auf die Figuren beschrieben, die schematisch

  • in der Figur 1 einen Ausschnitt eines Stapels 1 an Tuchprodukten 2 zeigen, wie er gemäß einer Ausführungsform in einer erfindungsgemäßen Packung enthalten ist, und
  • in der Figur 2 eine Gegenüberstellung des Absackverhaltens in einer erfindungsgemäßen Packung an Tuchprodukten 2 und in einer herkömmlichen Packung an Tuchprodukten 2 zeigen.
The invention will now be described in more detail using an exemplary embodiment and with reference to the figures, which are schematic
  • in the figure 1 show a section of a stack 1 of tissue products 2 as contained in a pack according to an embodiment of the invention, and
  • in the figure 2 show a comparison of the sagging behavior in a pack of tissue products 2 according to the invention and in a conventional pack of tissue products 2 .

Der Stapel 1 weist in der gezeigten Ausführungsform eine Vielzahl an Tuchprodukten 2 auf, die lagenweise aufeinander angeordnet sind. Dabei können die Tuchprodukte 2 der Länge nach waagerecht aufeinander angeordnet sein oder auch teilweise ineinander gefaltet sein, beispielsweise indem eine Lage Tuchprodukt 2 an einer Seite in die darüberliegende Lage Tuchprodukt 2 gefaltet ist, und an der gegenüberliegenden Seite in die darunterliegende Lage Tuchprodukt 2 gefaltet ist.In the embodiment shown, the stack 1 has a large number of tissue products 2 which are arranged in layers one on top of the other. The tissue products 2 can be arranged horizontally one on top of the other lengthwise or also partially folded into one another, for example by a layer of tissue product 2 being folded on one side into the layer of tissue product 2 above it and on the opposite side into the layer of tissue product 2 below it .

Nach jeweils fünf aufeinander angeordneten Lagen Tuchprodukt 2 weist der Stapel 1 eine Sperrschicht 3 auf, die aus einem flüssigkeitsundurchlässigen Material besteht. Auf diese Weise kann aus den getränkten Tuchprodukten austretendes und durch die Schwerkraft herabfließendes Tränkungsmittel maximal vier Lagen in der Packung nach unten fließen, bis es durch die Sperrschicht 3 gestoppt wird. Es bildet sich auf diese Weise nur zwischen den fünf zwischen den Sperrschichten 3 angeordneten Lagen Tuchprodukte 2 ein Flüssigkeitsgradient aus, nicht aber (wie im Stand der Technik) zwischen sämtlichen in der Packung enthaltenen Lagen Tuchprodukt 2. Der Flüssigkeitsgradient fällt dementsprechend viel geringer aus als im Stand der Technik beobachtet, und durch die (in der gezeigten Ausführungsform in regelmäßigen Abständen angeordneten) Sperrschichten 3 wird sichergestellt, dass sämtliche in der Packung bzw. im Stapel 1 angeordneten Tuchprodukte 2 auch nach einer Standzeit noch mit ausreichend Tränkungsmittel getränkt sind.After every five layers of tissue product 2 placed one on top of the other, the stack 1 has a barrier layer 3 which consists of a liquid-impermeable material. In this way, soaking agent that escapes from the soaked tissue products and flows down by gravity can flow down a maximum of four layers in the pack until it is stopped by the barrier layer 3 . In this way, a liquid gradient only forms between the five layers of tissue product 2 arranged between the barrier layers 3 , but not (as in the prior art) between all the layers of tissue product 2 contained in the pack. The liquid gradient is accordingly much lower than in the Prior art is observed, and the barrier layers 3 (arranged at regular intervals in the embodiment shown) ensure that all tissue products 2 arranged in the pack or in the stack 1 are still saturated with sufficient impregnating agent even after a period of standing.

Beispiel 1: Untersuchung des Absackverhaltens in einer erfindungsgemäßen Packung mit TuchproduktenExample 1 Investigation of the sagging behavior in a pack with tissue products according to the invention

Zur Untersuchung des Absackverhaltens in einer erfindungsgemäßen Packung mit Tuchprodukten 2 wurde der Flüssigkeitsgradient in einer solchen Packung im Vergleich zu einer herkömmlichen Packung mit Tuchprodukten 2 bestimmt.To investigate the sagging behavior in a pack of tissue products 2 according to the invention, the liquid gradient in such a pack was determined in comparison to a conventional pack of tissue products 2 .

Dazu wurden jeweils 20 aufeinander angeordnete Tuchprodukte 2 (Vliesstoff: 100% PET) aufeinander angeordnet und mit einer Menge an Tränkungsmittel von 4,5 g pro Gramm Vliesstoff getränkt. Fünf dieser Stapel mit jeweils 20 aufeinander angeordneten Tuchprodukten 2 wurden anschließend aufeinander angeordnet, wobei jeweils dazwischen, d.h. nach jeweils 20 Tuchprodukten, eine Lage mit einer flüssigkeitsundurchlässigen Folie aus thermoplastischer Stärke angeordnet wurde. Der Stapel 1 dieser insgesamt 100 getränkten Tuchprodukte mit den dazwischen angeordneten Sperrschichten wurde für 55 Stunden stehen gelassen. Danach wurde das Absackverhalten des Tränkungsmittels in dem Stapel 1 untersucht, indem von dem Stapel 1 jeweils von oben immer die obersten 10 Tücher abgenommen und gewogen wurden. Das Ergebnis ist in der nachfolgenden Tabelle 1 sowie in der Figur 2 (Kurve A) dargestellt. Tabelle 1: Untersuchung des Absackverhaltens in einer erfindungsgemäßen Packung mit Tuchprodukten Tücherzahl Flüssigkeitsmenge [g] Flüssigkeitsgradient 10 94,93 1,59 20 115,7 30 112,29 40 127,54 50 103,09 60 125,48 70 103,52 80 132,59 90 120,19 100 150,66 For this purpose, 20 cloth products 2 (nonwoven fabric: 100% PET) arranged one on top of the other were arranged one on top of the other and impregnated with an amount of impregnating agent of 4.5 g per gram nonwoven fabric. Five of these stacks, each with 20 tissue products 2 arranged one on top of the other, were then arranged one on top of the other, with a layer with a liquid-impermeable film between them, ie after every 20 tissue products made of thermoplastic starch. Stack 1 of these 100 total soaked wipe products with the barrier layers in between was allowed to stand for 55 hours. The sagging behavior of the impregnating agent in stack 1 was then examined by always removing and weighing the top 10 towels from stack 1 from above. The result is in Table 1 below and in the figure 2 (Curve A) shown. Table 1: Analysis of the sagging behavior in a pack with tissue products according to the invention number of cloths Amount of liquid [g] liquid gradient 10 94.93 1.59 20 115.7 30 112:29 40 127.54 50 103.09 60 125.48 70 103.52 80 132.59 90 120.19 100 150.66

Auf analoge Weise wurde das Absackverhalten in einer herkömmlichen Packung getränkter Tuchprodukte 2 ohne Sperrschicht 3 untersucht. Dazu wurde der gleiche Vliesstoff, das gleiche Tränkungsmittel und die gleiche Menge an Tränkungsmittel verwendet. Die insgesamt 100 getränkten Tuchprodukte wurden dann jedoch anschließend ohne dazwischenliegende Sperrschichten 3 aufeinander gelagert. Die Lagerung erfolgte ebenfalls für 55 Stunden. Danach wurde das Absackverhalten des Tränkungsmittels in dem Stapel 1 untersucht, indem von dem Stapel 1 jeweils von oben immer die obersten 10 Tücher abgenommen und gewogen wurden. Das Ergebnis ist in der nachfolgenden Tabelle 2 sowie in der Figur 2 (Kurve B) dargestellt. Tabelle 2: Untersuchung des Absackverhaltens in einer herkömmlichen Packung mit Tuchprodukten (Referenz) Tücherzahl Flüssigkeitsmenge [g] Flüssigkeitsgradient 10 48,14 2,25 20 56,39 30 63,40 40 78,41 50 87,61 60 102,85 70 109,36 80 119,21 90 124,54 100 134,94 The sagging behavior in a conventional pack of saturated tissue products 2 without a barrier layer 3 was examined in an analogous manner. The same non-woven fabric, the same impregnating agent and the same amount of impregnating agent were used for this. However, the total of 100 soaked tissue products were then subsequently stored one on top of the other without barrier layers 3 in between. Storage was also carried out for 55 hours. The sagging behavior of the impregnating agent in stack 1 was then examined by always removing and weighing the top 10 towels from stack 1 from above. The result is in Table 2 below and in the figure 2 (Curve B) shown. Table 2: Analysis of the sagging behavior in a conventional pack of tissue products (reference) number of cloths Amount of liquid [g] liquid gradient 10 48:14 2.25 20 56.39 30 63.40 40 78.41 50 87.61 60 102.85 70 109.36 80 119:21 90 124.54 100 134.94

Sowohl bei der erfindungsgemäßen Packung mit Tuchprodukten 2 als auch bei der Referenzpackung wurde der Flüssigkeitsgradient bestimmt. Dieser ist definiert als der Quotient aus der Menge bzw. dem Gewicht an Tränkungsmittel in den obersten zehn Lagen Tuchprodukten 2 und der Menge bzw. dem Gewicht an Tränkungsmittel in den untersten zehn Lagen Tuchprodukten 2 in dem Stapel 1. Für die erfindungsgemäße Packung mit Tuchprodukten 2 wurde dabei ein Flüssigkeitsgradient von 1,59 ermittelt und für die Referenzpackung mit Tuchprodukten 2 wurde ein Flüssigkeitsgradient von 2,25 ermittelt.The liquid gradient was determined both for the pack with tissue products 2 according to the invention and for the reference pack. This is defined as the quotient of the amount or the weight of impregnating agent in the top ten layers of tissue products 2 and the amount or the weight of impregnating agent in the bottom ten layers of tissue products 2 in the stack 1. For the pack of tissue products 2 according to the invention a liquid gradient of 1.59 was determined and for the reference package with tissue products 2 a liquid gradient of 2.25 was determined.

Es zeigt sich also, dass die erfindungsgemäße Sperrschicht 3 das Absackverhalten in einer Packung mit Tuchprodukten 2 deutlich verbessert, indem alle in einer Packung enthaltenen Tuchprodukte 2 auch nach längerer Standzeit noch eine völlig ausreichende Menge an Tränkungsmittel enthalten. Dies ist in einer Packung ohne Sperrschicht 3, wie sie im Stand der Technik in der Regel zu finden ist, nicht der Fall, denn bei einem Flüssigkeitsgradienten > 2 enthalten die oberen Tuchprodukte 2 einer Packung nur noch eine unzureichende Menge an Tränkungsmittel, während die unteren Tuchprodukte 2 einer Packung zu viel Tränkungsmittel enthalten. Die oberen Tuchprodukte 2 müssen daher oftmals ungenutzt entsorgt werden, da sie für die gewünschte Anwendung nicht genug Tränkungsmittel enthalten. Das sich am Boden der Packung ansammelnde überschüssige Tränkungsmittel muss in nicht erfindungsgemäßen Packungen ohne Sperrschicht ebenfalls ungenutzt entsorgt werden, sodass die Umwelt sowohl durch ungenutztes Tränkungsmittel als auch durch ungenutzte Tuchprodukte belastet wird. Dies wird durch die vorliegende Erfindung vermieden.It can thus be seen that the barrier layer 3 according to the invention significantly improves the sagging behavior in a pack with tissue products 2 , in that all tissue products 2 contained in a pack still contain a completely sufficient amount of impregnating agent even after a longer period of time. This is not the case in a pack without a barrier layer 3, as is usually found in the prior art, because with a liquid gradient > 2, the upper tissue products 2 of a pack only contain an insufficient amount of impregnating agent, while the lower Wipe products 2 in a pack contain too much saturant. The top towel products 2 therefore often have to be discarded unused because they do not contain enough impregnating agent for the desired application. The excess saturant that accumulates at the bottom of the pack must also be disposed of unused in packs not according to the invention without a barrier layer, so that the environment is polluted both by unused saturant and by unused tissue products. This is avoided by the present invention.
