Definitions
- the present invention relates to a pack or a stack with impregnated tissue products and a method for their production.
- wet wipes are nonwovens that are impregnated with a generally liquid composition that contains, among other things, a disinfecting, cleaning and / or caring 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.
- Impregnated pads are also nonwovens impregnated with a liquid composition, which as a rule differ from wet wipes only in their different format and, if necessary, in a higher material thickness of the nonwoven. Just like wet wipes, they offer the advantage of a convenient cleaning option that is generally 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 approx. 10 to 200 wipe products.
- a disadvantage of this type of packaging is that an uneven distribution of the impregnating agent in the packaging is often observed. Because in the stack of impregnated cloth products contained in the packaging, the impregnating agent sinks due to gravity after a comparatively short standing time, so that the cloth products located at the top of the stack no longer contain sufficient impregnating agent, while the cloth products located at the bottom of the stack contain an unnecessarily large amount of impregnating agent or are surrounded by too much impregnation agent. This limits the usability and in particular the effectiveness of the tissues located at the top of the stack.
- An alternative approach provides for the use of an impregnating agent with increased viscosity in order to reduce "sagging" of the impregnating agent in the pack.
- the increased viscosity is achieved by thickeners.
- This approach also has various disadvantages, because thickeners impair the effectiveness of many impregnating agents.
- 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.
- the EP 0 978 247 A1 describes a stack of impregnated wipes, which contains one or more evaporation protection layers between the impregnated wipes, by means of which the evaporation of volatile constituents of the impregnating agent is to be prevented.
- the evaporation protection layers are not necessarily impermeable to liquids.
- the evaporation protection layers are preferably hydrophobic and consist of polyethylene or polypropylene. However, this represents an additional burden for the environment, since these materials are not biodegradable, but are produced several times in each package as waste to be disposed of.
- the DE 10 2006 035 570 A1 describes a pack with disk-shaped or pad-shaped fiber composite articles, each comprising a fiber fleece layer soaked with a soaking liquid and a liquid-impermeable film layer that prevents liquid migration to the floor and evaporation and gives the article dimensional stability.
- 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 involves significantly increased effort and costs.
- 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 natural fibers and synthetic fibers, and pollute the environment as little as possible.
- the invention solves this problem with the features of the claims and in particular by providing a stack of towel products or a pack of towel products (so-called "flow pack") containing a stack which comprises a plurality of towel products arranged on top of one another, the towel products each having one comprise an impregnating agent impregnated nonwoven, and wherein in the stack comprising the cloth products arranged on top of one another, at least one barrier layer is also arranged, which comprises a material or consists of a material which has a different absorbency for the impregnation agent than the nonwoven fabric which the Cloth products comprise, and wherein the material that comprises or consists of the at least one barrier layer is a liquid-impermeable film made of biodegradable and / or compostable plastic.
- a wipe product is understood to mean, in particular, a pad or a wipe made of nonwoven material which can be soaked with a liquid composition.
- the impregnated towel products stacked according to the invention are also arranged on top of one another and optionally folded, for example in that a layer of towel product engages in each case with the overlying and the underlying layer of towel product.
- the stack of towel products according to the invention contains at least one barrier layer with or made of a material which has a different absorbency than the non-woven fabric which the towel products comprise. The barrier layer prevents the impregnating liquid from settling on the surface due to gravity Bottom of the pack or the stack accumulates because it is impermeable or substantially impermeable to liquids.
- the number of barrier layers provided for a pack of towel products and their positioning within the stack of towel products can be freely selected and should in particular be made dependent on the number of towel products contained in the stack. In small stacks of, for example, 10 towel products, a barrier layer placed between each 5 of the towel products may be sufficient. In this way, a liquid gradient forms above and below the barrier layer in the towel products contained in the stack, but because the barrier layer is impermeable to the impregnating agent, it is significantly lower than the liquid gradient in a corresponding stack of towel products without an intervening barrier layer.
- the arrangement of several barrier layers within the stack of tissue products is advisable, for example at a distance of 5, 10, 20 or 50 tissue products.
- the material that comprises the at least one barrier layer or of which it is made has a lower absorbency than the nonwoven fabric that the towel products comprise, the barrier layer being impermeable or substantially impermeable to liquids.
- the liquid-impermeable material that comprises the at least one barrier layer or of which it is made is, according to the invention, a film made of biodegradable and / or compostable plastic.
- 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.
- a barrier layer can be contained several times per pack depending on the size of the pack of towel products or depending on the amount of towel products contained in a pack, increased waste is created in each pack due to the barrier layers contained, which, however, due to the biodegradability or compostability of the liquid-impermeable film does not represent any additional pollution for the environment. Rather, the use according to the invention of biodegradable or compostable barrier layers in a pack of cloth products has the additional benefit Environmentally friendly effect that due to the more uniform distribution of liquid in a pack of wipe products due to the at least one barrier layer contained, fewer and preferably no wipe products are contained in a pack that contain too little impregnating agent, i.e. are too dry for the desired application, and are therefore unused must be disposed of.
- the stack contained in a pack of cloth products according to the invention comprises several layers of cloth products arranged one above the other, which are separated by a barrier layer from several further layers of cloth products arranged one above the other.
- the stack contained in a larger pack of cloth products preferably comprises several barrier layers which are spaced apart from one another by one or more layers of cloth products arranged one on top of the other.
- a pack of tissue products according to the invention contains a stack in which soaked tissue products are arranged alternately with barrier layers, i.e. a layer of barrier layer is arranged on each layer of tissue product, on which in turn a layer of tissue product is arranged.
- barrier layers i.e. a layer of barrier layer is arranged on each layer of tissue product, on which in turn a layer of tissue product is arranged.
- a pack of cloth products according to the invention contains a stack in which several layers of cloth product arranged one on top of the other, for example 2-20 layers of cloth product, more preferably 3 to 15 layers of cloth product and particularly preferably 5 to 10 layers of cloth product through a layer of barrier layer of in turn several layers of cloth product arranged on top of one another, for example 2-20 layers of cloth product, more preferably 3 to 15 layers of cloth product and particularly preferably 5 to 10 layers of cloth product, are separated.
- each impregnated cloth product contained in the stack contains a sufficient amount of impregnating agent so that the impregnated cloth products, regardless of whether they are arranged at the top or at the bottom of the stack, can reliably offer the desired cleaning success.
- the present invention is suitable without restriction for all nonwovens. Therefore, the nonwoven that is contained in a stack according to the invention of impregnated cloth products or in a pack according to the invention with impregnated cloth products can be a conventional nonwoven, in particular a nonwoven made of viscose fibers, polypropylene fibers, lyocell fibers, PET fibers, microfibers, cotton - Fibers or mixtures thereof or consists thereof.
- the nonwoven which is contained in a stack according to the invention of impregnated cloth products or in a pack according to the invention with impregnated cloth products consists of viscose fibers and / or Lyocell fibers and / or PET fibers, ie it can either be 100% Viscose fibers, Lyocell fibers or PET fibers, or they consist of mixed fibers.
- the nonwoven fabric optionally also contains microfibers and / or cotton fibers, for example in a proportion of up to 20% by weight each, in particular 0.1-5.0% by weight.
- the nonwoven fabric contained in a stack according to the invention of impregnated cloth products or in a pack according to the invention with impregnated cloth products consists of viscose fibers and / or Lyocell fibers and / or PET fibers and / or hemp fibers and / or cellulose fibers and / or flax fibers, and optionally also from 0.1-20.0% by weight microfibers and / or 0.1-20.0% by weight cotton fibers.
- the nonwoven which is contained in a stack according to the invention of impregnated cloth products or in a pack according to the invention with impregnated cloth products 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.
- 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.
- the impregnated wipe products contained in a stack according to the invention or a pack according to the invention can be impregnated with any impregnating agent, the impregnating agent being in particular a composition based on water, oil or alcohol, an oil-in-water emulsion or a water-in-oil -Emulsion can be and / or is selected in particular from the group that comprises or consists of cosmetic compositions or preparations, cleaning agents and disinfectants.
- Cosmetic compositions or preparations are understood to mean all types of liquid cosmetic compositions or preparations, including agents for facial and / or body cleansing and care, de-makeup, face masks, cures, skin care agents, cosmetic agents and agents that contain a medicinal or cosmetic active ingredient
- the active ingredient can be, for example, a compound with nourishing, greasy, moisturizing, soothing, moisturizing, anti-inflammatory, regenerative, wound healing, invigorating, firming, blood circulation-promoting, antimicrobial, fungicidal, bactericidal, antiallergic and / or antibacterial properties.
- Cleaning agents are understood to mean both agents for cleaning the body and agents for cleaning surfaces, e.g. floors.
- Disinfectants are understood to mean both skin disinfectants, in particular hand disinfectants, and surface disinfectants.
- the at least one barrier layer also contained in the pack of tissue products according to the invention is not accidentally used by 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.
- the invention also relates to a method for producing a pack of tissue products containing a stack which comprises a plurality of tissue products arranged one on top of the other, each comprising a nonwoven fabric soaked with an impregnating agent, wherein in the stack comprising the tissue products arranged one on top of the other also at least a barrier layer is arranged which comprises a material or consists of a material that has a different absorbency than the nonwoven fabric which the towel products comprise, wherein the at least one barrier layer is a liquid-impermeable film made of biodegradable and / or compostable plastic.
- a plurality of layers of cloth products arranged one on top of the other are preferably arranged between two barrier layers, the barrier layers and the cloth products together forming the stack.
- two layers of barrier layer 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.
- the cloth products, nonwovens, impregnating agents and barrier layers used in the method according to the invention can in particular be designed as described above with reference to the pack according to the invention with cloth products or the stack with cloth products.
- the stack 1 has a multiplicity of towel products 2 which are arranged in layers on top of one another.
- the towel products 2 can be arranged horizontally on top of one another lengthwise or partially folded into one another, for example by folding a layer of towel product 2 on one side into the layer of towel product 2 lying above and folding it into the layer of towel product 2 below on the opposite side .
- the stack 1 After five layers of cloth product 2 arranged one on top of the other, the stack 1 has a barrier layer 3 which consists of a liquid-impermeable material. In this way, impregnating agent emerging from the impregnated wipe products and flowing down under the force of gravity can flow down a maximum of four layers in the pack until it is stopped by the barrier layer 3.
- a liquid gradient is only formed between the five layers of cloth products 2 arranged between the barrier layers 3 , but not (as in the prior art) between all of the layers of cloth product 2 contained in the pack State of the art observed, and the barrier layers 3 (arranged at regular intervals in the embodiment shown) ensure that all of the tissue products 2 arranged in the pack or in the stack 1 are still soaked with sufficient impregnating agent even after a period of standstill.
- Example 1 Investigation of the sagging behavior in a pack according to the invention with cloth products
- tissue products 2 nonwoven: 100% PET
- an amount of impregnating agent of 4.5 g per gram of nonwoven.
- the stack 1 of a total of 100 impregnated wipe products with the barrier layers in between was left to stand for 55 hours.
- the sagging behavior of the impregnating agent in the stack 1 was then examined by always removing the top 10 wipes from the top of the stack 1 and weighing them.
- Table 1 Investigation of the sagging behavior in a pack according to the invention with cloth products Number of cloths Amount of liquid [g] Liquid gradient 10 94.93 1.59 20th 115.7 30th 112.29 40 127.54 50 103.09 60 125.48 70 103.52 80 132.59 90 120.19 100 150.66
- the liquid gradient was determined both in the case of the pack according to the invention with tissue products 2 and in the case of the reference pack. This is defined as the quotient of the amount or weight of impregnating agent in the top ten layers of cloth products 2 and the amount or weight of impregnating agent in the bottom ten layers of cloth products 2 in stack 1.
- a liquid gradient of 1.59 was determined and a liquid gradient of 2.25 was determined for the reference pack with cloth products 2.
- the barrier layer 3 improves the Absack in a package with tissue products 2 significantly by all wipe products 2 contained in a pack contain a fully sufficient amount of impregnating agent even after a prolonged service life. This is not the case in a pack without a barrier layer 3, as can usually be found in the prior art, because with a liquid gradient> 2, the upper wipe products 2 of a pack contain only an insufficient amount of impregnating agent, while the lower ones Towel products 2 in one pack contain too much impregnation agent. The upper towel products 2 therefore often have to be disposed of unused, since they do not contain enough impregnating agents for the desired application.
- the excess impregnating agent that collects at the bottom of the pack must likewise be disposed of unused in packs not according to the invention without a barrier layer, so that the environment is polluted both by unused impregnating agent and by unused cloth products. This is avoided by the present invention.

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, if necessary, in a higher material thickness of the nonwoven. Just like wet wipes, they offer the advantage of a convenient cleaning option that is generally 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.Both soaked pads and wet wipes are usually packaged in handy units of approx. 10 to 200 wipe products. However, a disadvantage of this type of packaging is that an uneven distribution of the impregnating agent in the packaging is often observed. Because in the stack of impregnated cloth products contained in the packaging, the impregnating agent sinks due to gravity after a comparatively short standing time, so that the cloth products located at the top of the stack no longer contain sufficient impregnating agent, while the cloth products located at the bottom of the stack contain an unnecessarily large amount of impregnating agent or are surrounded by too much impregnation agent. This limits the usability and in particular the effectiveness of the tissues located at the top of the stack.
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 towel 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 cloth products first removed from the pack are adequately soaked, while the top cloth products remaining in the pack become too Contains a small amount of impregnating agent. The problem is therefore only shifted to the extent that it is no longer the wipe products first removed from a pack that are insufficiently soaked, but rather the last removed.
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.An alternative approach provides for the use of an impregnating agent with increased viscosity in order to reduce "sagging" of the impregnating agent in the pack. The increased viscosity is achieved by thickeners. This approach also has various disadvantages, because 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.
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.Furthermore, attempts are also made to ensure the effectiveness of the cloth products located at the top of a stack by using a larger amount of impregnating agent, so that they still have a sufficiently high level of moisture even after the impregnating agent has sunk in the pack. However, this has the consequence that the manufacture of the wipe products becomes more expensive due to the increased need for impregnating agents and, moreover, due to gravity, even more impregnating agent collects at the bottom of a package and usually remains there unused.
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 for 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 the 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 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) .

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 stated that the prior art does not know any satisfactory and environmentally friendly solution that keeps the liquid gradient in soaked towel products packed in a stack within an acceptable range and thereby the effectiveness of all soaked towel products contained in the stack by a sufficient one Amount of impregnating agent contained in this guaranteed while avoiding the 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 that contains a stack of impregnated 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 is kept low in the pile of soaked cloth products. 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 natural fibers and synthetic fibers, and pollute the environment as little as possible.
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 towel products or a pack of towel products (so-called "flow pack") containing a stack which comprises a plurality of towel products arranged on top of one another, the towel products each having one comprise an impregnating agent impregnated nonwoven, and wherein in the stack comprising the cloth products arranged on top of one another, at least one barrier layer is also arranged, which comprises a material or consists of a material which has a different absorbency for the impregnation agent than the nonwoven fabric which the Cloth products comprise, and wherein the material that comprises or consists of the at least one barrier layer is a liquid-impermeable film made 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 wipe product is understood to mean, in particular, a pad or a wipe made of nonwoven material which can be soaked 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 towel products, the impregnated towel products stacked according to the invention are also arranged on top of one another and optionally folded, for example in that a layer of towel product engages in each case with the overlying and the underlying layer of towel product. Unlike conventional towel products, however, the stack of towel products according to the invention contains at least one barrier layer with or made of a material which has a different absorbency than the non-woven fabric which the towel products comprise. The barrier layer prevents the impregnating liquid from settling on the surface due to gravity Bottom of the pack or the 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 towel products and their positioning within the stack of towel products can be freely selected and should in particular be made dependent on the number of towel products contained in the stack. In small stacks of, for example, 10 towel products, a barrier layer placed between each 5 of the towel products may be sufficient. In this way, a liquid gradient forms above and below the barrier layer in the towel products contained in the stack, but because the barrier layer is impermeable to the impregnating agent, it is significantly lower than the liquid gradient in a corresponding stack of towel products without an intervening barrier layer.
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, the arrangement of several barrier layers within the stack of tissue products is advisable, 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.According to the invention, the material that comprises the at least one barrier layer or of which it is made has a lower absorbency than the nonwoven fabric that the towel products comprise, 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.The liquid-impermeable material that comprises the at least one barrier layer or of which it is made is, according to the invention, a film made 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 towel products or depending on the amount of towel products contained in a pack, increased waste is created in each pack due to the barrier layers contained, which, however, due to the biodegradability or compostability of the liquid-impermeable film does not represent any additional pollution for the environment. Rather, the use according to the invention of biodegradable or compostable barrier layers in a pack of cloth products has the additional benefit Environmentally friendly effect that due to the more uniform distribution of liquid in a pack of wipe products due to the at least one barrier layer contained, fewer and preferably no wipe products are contained in a pack that contain too little impregnating agent, i.e. are too dry for the desired application, and are therefore unused must 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 pack of cloth products according to the invention comprises several layers of cloth products arranged one above the other, which are separated by a barrier layer from several further layers of cloth products arranged one above the other.
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 several barrier layers are necessary or advisable in larger packaging units, the stack contained in a larger pack of cloth products preferably comprises several barrier layers which are spaced apart from one another by one or more layers of cloth products arranged one on top of the other.
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 pack of tissue products according to the invention contains a stack in which soaked tissue products are arranged alternately with barrier layers, i.e. a layer of barrier layer is arranged on each layer of tissue product, on which in turn a layer of tissue product is arranged. In this way, the exactly desired amount of impregnating agent always remains in the wipe product, since each wipe product is delimited both upwards and downwards by a layer of liquid-impermeable barrier layer.
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 cloth products according to the invention contains a stack in which several layers of cloth product arranged one on top of the other, for example 2-20 layers of cloth product, more preferably 3 to 15 layers of cloth product and particularly preferably 5 to 10 layers of cloth product through a layer of barrier layer of in turn several layers of cloth product arranged on top of one another, for example 2-20 layers of cloth product, more preferably 3 to 15 layers of cloth product and particularly preferably 5 to 10 layers of cloth product, are separated. In this way there are 2-20 layers of cloth product, more preferably 3 to 15 layers of cloth product and particularly preferably 5 to 10 layers of cloth product between two barrier layers, whereby the impregnating agent can only flow down between two barrier layers due to gravity, but not into the cloth products arranged below the delimiting barrier layer or even to the bottom of the pack. The liquid gradient in the pack is kept low in this way and is naturally smaller, the fewer layers of tissue products are arranged between two barrier layers are. By choosing a suitable amount of barrier layers used per stack and by positioning them appropriately, in particular at a constant distance of a few layers of cloth products, it is ensured that each impregnated cloth product contained in the stack contains a sufficient amount of impregnating agent so that the impregnated cloth products, regardless of whether they are arranged at the top or at the bottom of the stack, can reliably offer the desired cleaning success.

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 according to the invention or a pack according to the invention can be impregnated with any impregnating agent, the impregnating agent being in particular a composition based on water, oil or alcohol, an oil-in-water emulsion or a water-in-oil -Emulsion can be and / or is selected in particular from the group that comprises or consists of cosmetic compositions or preparations, cleaning agents and 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 of tissue products according to the invention is not accidentally used by 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 which comprises a plurality of tissue products arranged one on top of the other, each comprising a nonwoven fabric soaked with an impregnating agent, wherein in the stack comprising the tissue products arranged one on top of the other also at least a barrier layer is arranged which comprises a material or consists of a material that has a different absorbency than the nonwoven fabric which the towel products comprise, wherein the at least one barrier layer is a liquid-impermeable film made 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.

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 multiplicity of
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 five layers of
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
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
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
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 in the case of the pack according to the invention with
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 is therefore apparent that the
Die in der vorstehenden Beschreibung, in den Figuren sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in beliebigen Kombinationen für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.The features of the invention disclosed in the above description, in the figures and in the claims can be essential both individually and in any combination for the implementation of the invention in its various embodiments.
