Abstract

The The present invention relates to a laminated absorbent acquisition and distribution layer structure for sanitary articles, comprising at least one cover layer containing at least one nonwoven, the made by spunlace technique and that at least partially is provided with hydrophilic properties, and at least one Transfer layer containing at least one nonwoven, which by means of through-air Bonding technology is made and that at least partially equipped with hydrophilic properties, wherein the nonwoven the cover layer and the nonwoven fabric of the transfer layer by means of hydroentanglement represent formed laminate. This absorbent layer structure characterized by a very uncomplicated production in industrial scale as well as by a textile-like feeling surface and can about it simple, reliable and permanently with an embossed pattern be provided. Furthermore, the invention relates to a method for Production of the Layer Structure According to the Invention and absorbent articles containing this layered structure.

Description

  • The The present invention relates to an acquisition and distribution layer structure for absorbent Hygienic articles in the form of a laminate of at least one cover layer and at least one transfer layer, a process for their preparation and an absorbent article containing this layered structure. Furthermore, the invention relates to sanitary napkins, diapers, incontinence protection products, bandages, wipes, panty liners and hygiene products for the personal hygiene, containing the layer structure according to the invention.
  • absorbent Articles are nowadays used in many different applications. Exemplary are only hygiene products for personal care, diapers, cleaning supplies for the Household or medical applications called. Because these disposable products in big Quantities are used and in demand, it is a constant effort, not only the products as such, but also their large-scale Optimize production. In particular, it is desirable to have absorbent articles To fall back on to be able to the opposite usual Articles have a smaller volume and a lower weight, however, in terms of their absorption properties and their wearing comfort no loss of quality to accept to have.
  • In the US 6,022,818 For example, a hydroentanglement-associated absorbent structure is described from a first layer containing absorbent fibers, eg, pulp fibers, and a second layer containing so-called matrix fibers, eg, polyolefin staple fibers. While the pulp fibers serve to hold liquid, the absorption capacity of the matrix fibers is less pronounced in order to be able to supply liquid to the absorbent layer. According to the US 6,022,818 For example, the layer of matrix fibers can be made by through-air bonding technique using bicomponent fibers containing a polyethylene sheath and a polyester core. The after the US 6,022,818 However, products obtained, for example sanitary napkins or diapers, still leave something to be desired, in particular with regard to the absorption capacity, the surface grip, the complexity of the production process and the embossability of the surface.
  • The EP 0 557 678 A1 discloses a hydroentangled composite nonwoven having a spunbonded base layer. This structure is said to be compared with spun lacing produced hydroentangled layers, such as in the US 4,442,161 and the US 4,705,712 characterized by a tensile strength that is equally pronounced in the machine direction and transverse to the machine direction. For this purpose, the spunbonded in the direction transverse to the machine direction Rich by at least 5% of its original length to stretch. The necessity of having to integrate the stretching step in the large-scale, fully automatic production process inevitably causes a greater production cost and production costs.
  • From the patent application US 20030028985 A1 shows a multi-layer cleaning pad, comprising a cleaning layer, a wiper layer and an absorber layer. Among other things, a nonwoven material is proposed for the wiping layer which is accessible by means of hydroentanglement / spun lacing and through-air bonding technology and can be composed of, for example, cellulose fibers or rayon or polyolefin fibers. The nonwoven wipe layer is preferably hydrophilic. Whether and to what extent the characteristics of the multi-layer cleaning pad according to the patent application US 20030028985 A1 can be transferred to absorbent hygiene products, is left completely open in this document. Also, with such cleaning articles, there is often no need to reduce the weight or volume of the absorbent article. In particular, this document also does not deal with interactions or effects that can be obtained by combining separate, laminated layers, each with a characteristic property profile.
  • In the US 6,107,539 there is described an absorbent article comprising a front and a backsheet and a liquid collection and distribution region and another region for storing this liquid. In this case, the cover layer may include the area for receiving and distributing liquid and, for example, consist of a cellulosic fiber material. Furthermore, the liquid transport between adjacent distribution and storage areas can be improved by incorporating a thin intermediate layer. The intermediate layer can be obtained, for example, by depositing fibrous material on a porous material by means of air-laying. With the in the US 6,107,539 It should be possible to store liquid more strongly in the absorbent core and, moreover, to ensure an always dry-feeling surface. The absorbent article according to the US 6,107,539 However, it is very complicated to set up and expensive to manufacture, especially in mass production. The machinability of the surface also leaves something to be desired.
  • The present invention is therefore based on the object of making available an absorbent article which is also inexpensive and uncomplicated in automated mass production can be made whose surface feels like a textile surface and can be easily and permanently embossed with any pattern. A further object of the present invention is to provide an absorbent article which is distinguished by a further reduced density or a reduced basis weight compared to conventional products, without at the same time having to accept losses in its absorption and retention properties.
  • Accordingly, became a laminated acquisition and distribution layer structure for absorbent Hygiene article found, comprising at least one cover layer, which contains at least one fleece, the made by spunlace technique and that at least partially is provided with hydrophilic properties, and at least one transfer layer, which contains at least one fleece, which is produced by means of through-air bonding technology and the at least partially equipped with hydrophilic properties wherein the fleece of the cover layer and the fleece of the transfer layer represent a hydroentanglement formed laminate.
  • Under Nonwovens for the purposes of the present invention are intended to be so-called nonwovens be understood. The spunlace technique, also called spunlacing, is usually used to make very soft and flexible fiber webs used and includes a meshing of the fibers below Training a coherent Location. Under spunlacing in the context of the present invention are intended also the methods of water jet needling or the Hydroentanglement with included be. This manufacturing process is for example of a kadierten fiber web, wherein the interlacing of the fibers is achieved in that the fibers with a plurality of adjacent, very fine water jets are subjected under high pressure. For example, you can several rows of water jets directed at the fiber web, which is carried by a mobile network. This procedure finds also described as a so-called hydroentangling process With water jets, the turbulence or interlocking can the fibers of a nonwoven web also by fine high pressure air jets be effected.

In addition, designed the logistics of for the manufacturing process available compared to components usual Production process very simple and straightforward. Although the same Fiber materials for the cover and the transfer layer can be used, differentiate Nevertheless, both layers are functional in their functionality, so that the combined property profiles conventional, from different Materials of existing multi-layer absorbent article systems already with the structure according to the invention can be covered.
  • The transfer layer of the layer structure according to the invention ensures a very good distribution behavior with respect to the absorbed liquid, has a sufficient thickness despite minimal use of material and at the same time also to some extent has fluid absorption properties. The top layer has an excellent recording or acquisition character In addition, it contributes to a very good and lasting embossability of the shift structure.
  • When especially advantageous for especially medical and hygienic applications has proven that to maintain and maintain the integrity of deck and transfer layer and the laminate formed from these layers, no binding and / or adhesives are required. On the use of so-called Construction adhesive materials commonly used in nonwoven webs come, can completely be waived without loss in terms of the strength of the fleece to have to accept. From Another advantage is that the fluid absorption properties the layer structure according to the invention not be affected by such adhesive materials.

In this way, an additional embossing station can be saved. To effect this, it is already sufficient in many cases, the pad, on which the transfer layer and the cover layer rest, with a three-dimensional negative mold of the desired embossing pattern equip. Advantageously, this negative mold has passages or openings, through which the applied amounts of water can flow.
  • According to one Another aspect of the present invention is an absorbent Article provided, which, in this order, at least one layer structure according to the invention, at least one absorbent core, in particular immediately adjacent to the transfer layer of the layered structure, and optionally at least one fluid-impermeable Barrier layer has. Such absorbent articles include for example sanitary napkins, diapers, incontinence protection articles, bandage materials, Panty liners and wipes. Further Is it possible, Also to equip tampons with the absorbent article.
  • The object underlying the invention is further achieved by a method for producing a laminated absorbent acquisition and distribution layer structure for absorbent hygiene articles, comprising the steps:
    • a) producing at least one nonwoven fabric for at least one cover layer comprising a top and an opposite underside of hydrophilic fibers and / or fibers having a hydrophilic coating by means of spunlace technique,

It is of course also possible that in step c) the cover layer and the transfer layer in the laminated Condition after hydroentanglement with at least one embossed pattern be provided.
  • With the absorbent articles of the present invention is the surprising Accompanying knowledge, in a simple manufacturing technology To be able to receive a product the above has a very low basis weight, but sufficiently thick is and about a very good liquid absorbency and a very good liquid distribution characteristic features. By combining two nonwoven layers, each according to a special Processes have been made, one of the spunlace technique for the Top layer and on the other hand, the through-air bonding technique for the transfer layer, can even when using identical materials, absorbent laminate systems are obtained, whose individual layers have different functions which complement each other in a very effective way. When Particularly advantageous has been found that the absorbent of the invention Article completely unproblematic and also be permanently provided with an embossed pattern. The Products obtained in this way are especially after the embossing process with a surface equipped that feels like as if it were a textile surface. The comfort of the with Products made of these absorbent articles, for example diapers or sanitary napkins, can thus sustainably increased. Unlike conventional absorbent articles are also not required in the present case to the quality or property improvement the absorbent article a stretching process to undergo. As a result, the production process according to the invention is very simple being held.
  • With Help the layer structure according to the invention can be achieved by combining a spunlace technique obtained cover layer and a through-air bonding technique obtained transfer layer For example, especially panty liners particularly efficient produce. By fibers of the cover layer with fibers of the transfer layer be interwoven by the hydro-entanglement process, without it for that one chemical process or an adhesive material needed succeed an improved fluid absorption and also an improved Distribution of fluids over the entire extent of the layer structure. Remarkably Furthermore, that by means of Wasserstrahlprägens in the layer structure according to the invention received embossing pattern show very clear and permanent edge or edge courses. In addition, pits with a wide variety of depths are possible into the layer material by means of water jet embossing. Further, from significant advantage that treated by Wasserstrahlprägens Layer structures according to the invention no longer or only greatly reduced tend to frazzle, which considerably increases the wearing comfort. With the laminate according to the invention it is, moreover possible, for the a cover layer fleece produced by means of spunlace technique lower basis weight to use. This results in a very thin layer structure allows however we use the layer material according to the invention as a structure with a pronounced perceived three-dimensional extent.
  • Compared to conventional, commercially available Layer or Absorbtionsstrukturen is the layer structure of the invention at least in terms of rewettability and absorbency par. Under rewettability or rewettability in the present case, the retention or retention capacity of the layer structure in Be understood with regard to recorded fluid.
  • Thus, the layer structure according to the invention is characterized by an improved embossability, an improved absorption capacity and also by improved acquisition and distribution characteristics. With the layer structure according to the invention, it is now even possible to obtain liquid and to distribute it appropriately.
  • Surprisingly was also found that the laminated layer structure according to the invention or a fabric web of this layer structure by an improved uniformity distinguished. Also, no delamination phenomena between cover and transfer layer observed, and although no binder or adhesive between these layers are used. In this way, moreover, can be the production process of the layer structure according to the invention very much easy to represent.
  • Further Features and advantages of the invention will become apparent from the following Description, in an embodiment will be explained in detail with reference to a schematic drawing. there this figure shows a schematic side view of a device for the Production of the Layer Structure According to the Invention
  • The layer structure 1 is made up of a topcoat 2 and a transfer layer 4 together. The nonwoven web of the top layer 2 will happen after passing the carding unit 6 a hydro vortex device 8th fed. The transfer layer produced by through-air-bonding technology 4 after passing through a through-air bonding device 10 also the hydro-swirling device 8th fed. This hydro-swirling device 8th comprises an at least partially perforated cylinder 16 on which the topcoat 2 and the transfer layer 4 rest, leaving the topcoat 2 is in direct contact with the cylinder surface while the transfer layer 4 at least in the areas on the underside of the topcoat 2 rests in which the hydro-turbulence by means of hydrodynamic unit 12 as part of the device 8th goes on. The hydrodynamic unit 12 has a large number of water jet nozzles, through each of which a very fine high-pressure water jet can be applied to the transfer layer. Already during the formation of the laminate of cover and transfer layer by means of hydroentanglement, one or more patterns can be incorporated into the layer structure, in particular from the side of the cover layer, by suitable configuration of the surface of the cylinder. In one of the hydro turbulence unit 12 downstream water jet embossing device 14 can then further or can then be incorporated for the first time an embossing pattern in the layer structure. The material obtained in this way is particularly suitable as a cover layer system for panty liners and sanitary napkins. It is characterized by a particularly soft surface, which feels on the skin like conventional textile fabric and thus guarantees a very high wearing comfort.
  • The rewettability or the retention capacity and the absorption capacity of a laminated structure according to the invention are reproduced by way of example below. This laminate structure comprises a cover layer made of 65% by weight of viscose fibers and 35% by weight of PET fibers produced by means of spunlace technology and a transfer layer made of 70% by weight of bicomponent fibers "ES-Delta" produced by through-air bonding FiberVisions and 30% by weight PET fibers "Fillwell" from Wellmann. Cover and transfer layer were connected by means of hydroentanglement. The basis weight of the cover layer was 55 g / m 2 , that of the transfer layer 40 g / m 2 .
  • The absorbance the in outline form a sanitary napkin present laminate structure was tested by 7 ml of aqueous test liquid were dripped onto a point of the cover layer in such a way that each Drop penetrated into the laminate structure and was absorbed. Of the Period between the onset of the first fluid drop and the complete absorption the last drop of liquid was about 14 seconds.
  • The retention capacity of this laminate structure was determined in such a way that the preceding described, with liquid soaked product covered with ten layers of filter paper MN 615 (Macherey and Nagel) and for was weighted for three minutes with a weight of 5 kg. The difference between the weight of the filter paper in the dry state and after three minutes Contact with the test liquid containing a laminate structure provides a measure of their retention capacity and was in the present case 1.4 g.
  • The in the foregoing description, in the drawing and in the claims disclosed features of the invention both individually and in any combination for the realization be essential to the invention in its various embodiments.
