Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Verfahren anzugeben, durch welches auf einfache Weise ein elastisches, luftdurchlässiges Flächengebilde mit Hilfe von elastischen Schmelzklebstoffen zu fertigen ist.In front In this background, the invention is based on the object Specify a method by which in a simple way an elastic, air-permeable fabric is to produce with the help of elastic hot melt adhesives.
Gegenstand der Erfindung und Lösung der Aufgabe ist ein Verfahren zur Herstellung eines elastischen Flächengebildes, das eine Mittelschicht aus einem gummielastischen Gitterwerk zwischen, zwei porösen Außenlagen aus Fasermaterial aufweist, wobei Klebstoffstränge aus einem bei Raumtemperatur elastischen Schmelzklebstoff in erhitztem dünnflüssigen Zustand mit einer Dicke von mehr als 0,1 mm auf mindestens eine der die Außenlagen bildenden Materialbahnen aufgetragen werden, wobei die Materialbahnen aufeinandergelegt und durch die Klebstoffstränge verbunden werden, wobei die Klebstoffstränge zu einem bei Raumtemperatur gummielastischen Gitterwerk erstarren, welches unter Zugbeanspruchung dehnbar ist und sich bei einer Zugentlastung zurückstellt, und wobei die aus Fasermaterial bestehenden Materialbahnen eine bevorzugte Dehnungsrichtung quer zur Bahnrichtung aufweisen, die von dem elastischen Gitterwerk aufgenommen wird.object the invention and solution The object is a method for producing an elastic Fabric, a middle layer of a rubber-elastic lattice between, two porous outer layers made of fibrous material, wherein adhesive strands of one at room temperature elastic hot-melt adhesive in a heated low-viscosity state with a thickness of more than 0.1 mm on at least one of the outer layers forming material webs are applied, wherein the material webs superimposed and connected by the adhesive strands, wherein the glue strands to a rubber-elastic grid at room temperature, which is stretchable under tensile stress and at a strain relief reset, and wherein the material webs consisting of fiber material a preferred direction of elongation transverse to the web direction, the is absorbed by the elastic lattice work.
Im vorliegenden Falle wird der Klebstoff als solcher elastisch ausgestattet, so dass eine hochelastische Mittelschicht entsteht, die auch dann eine Elastizität des Flächengebildes ergibt, wenn die Fasermaterialien, die die Auslagen bilden, zwar leicht verzogen werden können, aber in sich unelastisch sind.in the In this case, the adhesive is elastically equipped as such, so that a highly elastic middle layer is formed, even then an elasticity of the fabric results when the fiber materials that make up the displays, though can easily be warped, but are inelastic in themselves.
Mit Vorteil kann die Konfiguration der Klebstoffstränge mittels eines Druckverfahrens, insbesondere Tiefdruckverfahrens aufgebracht werden. Das Aufbringen der Klebstoffstränge erfolgt dabei gitterförmig auf eine oder auf beide Materialbahnen. Nach dem gitterförmigen Aufbringen werden die Bahnen aufeinandergelegt und mit Hilfe des thermoplastischen Klebstoffes verklebt. Hierbei kann beispielsweise ein beheiztes Tiefdruckwerk verwendet werden, dessen Tiefdruckzylinder dergestalt graviert sind, dass ein gitterförmiger, waffelartiger Auftrag auf die Vliesstoffbahn erfolgt.With Advantage may be the configuration of the adhesive strands by means of a printing process, in particular gravure printing method are applied. The application the adhesive strands takes place in a grid shape on one or both webs. After the latticed application the sheets are stacked and with the help of thermoplastic Adhesive glued. Here, for example, a heated Gravure printing can be used, the gravure cylinder like engraved are that a grid-shaped, Waffle-like order is made on the nonwoven web.
Als Vliesstoffe eignen sich solche, die in an sich bekannter Weise auf einem Legeband hergestellt werden und nach dem Spinnvliesverfahren oder dem Schmelzblasverfahren gebildet sein können. Dabei kann die Dicke des Vlieses sehr unterschiedlich sein. Es sei auch nicht ausgeschlossen, dass der aufgebrachte Klebstoffstrang wenigstens teilweise in das Vliesmaterial eindringt und eine hohe Verankerung bewirkt. Gemäß der Erfindung wird ein besonderer Wert auf die Konfiguration der Klebstoffstränge gelegt. Diese können in parallelen geraden oder mäandrierenden Streifen aufgebracht sein. Vorzugsweise handelt es sich jedoch um Klebstoffstränge, die in zueinander spiegelbildlichen Zick-Zack- oder Sinuskurven verlaufen, die sich in ihren Scheiteln jeweils überlappen oder berühren, so dass eine waffelartige Konfiguration entsteht.When Nonwovens are those which, in a conventional manner a laying belt and after the spunbonding process or the meltblown process. The thickness can be of the fleece be very different. It is also not excluded that the applied adhesive strand at least partially in the Nonwoven material penetrates and causes a high anchorage. According to the invention special emphasis is placed on the configuration of the adhesive strands. these can in parallel straight or meandering Be applied stripes. Preferably, however, it is about Adhesive beads, the mirrored zigzag or sinusoids run, which overlap or touch each other in their vertices, so that a waffle-like configuration is created.
Der Klebstoffauftrag kann beispielsweise durch Mehrfachdüsen erfolgen. Es kann auch durch entsprechend gegeneinander bewegbare Düsen ein waffelartiger, gitterartiger oder rechteckförmiger Auftrag erfolgen. Nicht ausgeschlossen werden soll auch, dass im Randbereich eines Flächengebildes, das beispielsweise dazu dient, zu Slipeinlagen, Monatsbinden oder dergleichen verarbeitet zu werden, eine höhere Klebstoffdichte besteht als im Mittelbereich. Immer handelt es sich um Klebstoffe, die bei Zimmertemperatur elastisch bleiben und als Heißkleber verarbeitet werden können.Of the Adhesive application can be done for example by multiple nozzles. It can also by correspondingly mutually movable nozzles a waffle-like, grid-like or rectangular Order done. It should not be excluded that in the Edge region of a fabric, the for example, serves to panty liners, sanitary napkins or the like to be processed, a higher Adhesive density exists as in the middle area. Always it is to adhesives that remain elastic at room temperature and as hot glue can be processed.

Mit dem vorgenannten Verfahren lassen sich "atmungsfähige" Flächengebilde herstellen, wie sie insbesondere für Hygieneartikel, wie Slipeinlagen, Windeln, Inkontinenzeinlagen und dergleichen benötigt werden. Die Elastizität eines solchen Flächengebildes ist durch die besondere Mittelschicht gewährleistet. Die Produktion kann auch mit hoher Geschwindigkeit erfolgen, da beheizte Druckzylinder, mit denen ein Hot-Melt-Thermoplast aufgebracht werden kann, bekannt sind, die mit hoher Umdrehungsgeschwindigkeit arbeiten. Der Klebstoff kann beispielsweise aus SBS, aus Metallocen-Polyolefinen oder dergleichen bestehen.With The above method can be "breathable" fabrics produce, in particular for hygiene articles, such as panty liners, diapers, incontinence pads and the like needed become. The elasticity such a fabric is ensured by the special middle class. The production can also be carried out at high speed, as heated pressure cylinders, with where a hot-melt thermoplastic can be applied known are those who work at high rotation speed. The adhesive may be, for example, SBS, metallocene polyolefins or the like consist.
