Abstract
Description
Die Erfindung betrifft ein mehrschichtiges elastisches Flächengebilde, das aus wenigstens zwei Außenlagen aus einem porösem Fasermaterial, wie Vlies aus polyolefin ischen Fasern, und aus wenigstens einer Mittelschicht, die aus linienförmig aufgebrachten Klebstoffsträngen besteht, aufgebaut ist.The invention relates to a multilayer elastic Fabric made up of at least two outer layers a porous fiber material, such as a polyolefin fleece fibers, and from at least one middle layer, those made of lines of adhesive exists, is built.
Aus der DE-AS 28 35 822 "Absorptionsfähiger Schichtstoff und Verfahren" ist ein Schichtstoff bekannt, der aus zwei aus Zellulosefasern gebildeten Sauglagen und einer Mittelschicht besteht, wobei letztere ein punkt- oder streifenförmig verteilter Klebstoff ist, der auch aus sich kreuzenden Linien gebildet sein kann.From DE-AS 28 35 822 "Absorbent laminate and process "a laminate is known which consists of two suction layers formed from cellulose fibers and one Middle class exists, the latter a point or Strip-like distributed adhesive that is also made of crossing lines can be formed.
Ausgehend von diesem Stand der Technik stellt sich die Aufgabe, ein mehrschichtiges Flächengebilde anzugeben, das eine luftdurchlässige, hochelastische Materialbahn mit Hilfe von Schmelzklebstoffen ergibt.Based on this state of the art, the Task of specifying a multi-layer fabric, which is an air-permeable, highly elastic material web with the help of hot melt adhesives.
Diese Aufgabe wird gelöst durch ein Flächengebilde der eingangs genannten Art, das dadurch gekennzeichnet ist, daß der Klebstoffstrang aus einem bei Raumtemperatur elastischen Thermoplasten besteht und daß die Konfigura tion der Klebstoffstränge ein Gitterwerk beschreibt, das eine elastische Dehnung unter Zugbeanspruchung und Rück stellung der Klebstoffstrang-Konfiguration erlaubt.This problem is solved by a flat structure of the type mentioned at the beginning, which is characterized in that the adhesive strand from a at room temperature elastic thermoplastics and that the configura tion of the adhesive strands describes a latticework that elastic stretching under tension and back position of the adhesive strand configuration allowed.
Während bei der Konfiguration der Klebstoffstränge gemäß Fig. 2 des eingangs genannten Standes der Technik ledig lich darauf geachtet worden ist, daß die Klebstoffvertei lung eine Luftdurchlässigkeit nicht unterbricht, wird im vorliegenden Falle der Klebstoff als solcher elastisch ausgestattet, so daß eine hochelastische Mittelschicht entsteht, die auch dann eine Elastizität des Flächenge bildes ergibt, wenn die Fasermaterialien, die die Außen lagen bilden, zwar leicht verzogen werden können, aber in sich unelastisch sind.While in the configuration of the adhesive strands according to FIG. 2 of the prior art mentioned at the outset, care was taken only that the adhesive distribution does not interrupt air permeability, in the present case the adhesive as such is provided with elastic so that a highly elastic middle layer is formed, which also results in an elasticity of the surface image if the fiber materials that form the outer layers can be easily warped, but are inherently inelastic.
Mit Vorteil kann die Konfiguration der Klebstoffstränge mittels eines Druckverfahrens aufgebracht werden. Hierzu eigenen sich übliche Druckverfahren, z. B.. Tiefdruck, Flexodruck oder Siebdruck. Das Aufbringen der Klebstoff stränge erfolgt dabei gitterförmig auf eine oder auf beide Materialbahnen. Nach dem gitterförmigen Aufbringen werden die Bahnen aufeinander gelegt und mit Hilfe des thermoplastischen Klebstoffes verklebt. Hierbei kann bei spielsweise ein beheiztes Tiefdruckwerk verwendet werden, dessen Tiefdruckzylinder dergestalt graviert sind, daß ein gitterförmiger, waffelartiger Auftrag auf die Vliesstoffbahn erfolgt. Ähnliches gilt für die Druck verfahren Flexodruck oder Siebdruck.The configuration of the adhesive strands can be advantageous be applied by means of a printing process. For this are usual printing processes, e.g. B .. gravure, Flexographic or screen printing. Applying the glue strands are lattice-shaped on or on both material webs. After the grid-shaped application the tracks are laid on top of each other and with the help of glued thermoplastic adhesive. Here, at used for example a heated gravure printing unit are engraved in such a way are that a lattice-like, waffle-like order the nonwoven web is made. The same applies to printing process flexo printing or screen printing.
Als Vliesstoffe eignen sich solche, die in an sich bekannter Weise auf einem Legeband hergestellt werden und nach dem Spinnvliesverfahren oder dem Schmelzblasver fahren gebildet sein können. Dabei kann die Dicke des Vlieses sehr unterschiedlich sein. Es sei auch nicht aus geschlossen, daß der aufgebrachte Klebstoffstrang wenig stens teilweise in das Vliesmaterial eindringt und eine hohe Verankerung bewirkt. Gemäß Erfindung wird ein beson derer Wert auf die Konfiguration der Klebstoffstränge gelegt. Diese können in parallelen geraden oder mäandrierenden Streifen aufgebracht sind. Vorzugsweise handelt es sich jedoch um Klebstoffstränge, die in zuein ander spiegelbildlichen Zick-Zack- oder Sinuskurven ver laufen, die sich in ihren Scheiteln jeweils überlappen oder berühren, so daß eine waffelartige Konfiguration entsteht.Suitable nonwovens are those which are in themselves be made in a known manner on a laying tape and after the spunbond process or the melt blower driving can be formed. The thickness of the Fleece can be very different. It wasn't over either concluded that the applied strand of adhesive little Mostly penetrates into the nonwoven material and one high anchoring effect. According to the invention, a particular the value on the configuration of the adhesive strands placed. These can be in parallel straight lines or meandering stripes are applied. Preferably however, there are strands of adhesive that go in together other mirror-image zigzag or sine curves run, which overlap in their apexes or touch, making a waffle-like configuration arises.
Es ist auch möglich, die Klebstoffstränge mit Hilfe einer ventilgesteuerten Düse regelmäßig zu unterbrechen, so daß immer nur relativ kurze Abschnitte entstehen, die ebenfalls die Elastizität des Flächengebildes gewähr leisten.It is also possible to use the adhesive strands to interrupt a valve-controlled nozzle regularly, so that only relatively short sections arise, the also ensure the elasticity of the fabric Afford.
Die Erfindung betrifft ferner ein Verfahren zur Herstel lung eines mehrschichtigen elastischen Flächengebildes, das aus wenigstens zwei Außenlagen aus porösem Faser material und aus wenigstens einer gummielastischen Mittelschicht aufgebaut ist.The invention further relates to a method of manufacture development of a multilayered elastic fabric, that of at least two outer layers of porous fiber material and from at least one rubber elastic Middle class is built.
Das Verfahren ist dadurch gekennzeichnet, daß mittels eines Druckverfahrens oder Strangausdrückens Klebstoff stränge, die aus einem bei Raumtemperatur elastischen Thermoplasten bestehen, derart auf ein Substrat aus porö sem Fasermaterial aufgebracht werden, daß die Konfigura tion der Klebstoffstränge ein zweidimensionales Gitter werk ergibt, das unter Zugbeanspruchung und -aufhebung eine elastische Dehnung und Rückstellung der Klebstoffstrang-Konfiguration erlaubt.The method is characterized in that a printing process or extruding adhesive strands made of an elastic at room temperature Thermoplastics consist of poro on a substrate Sem fiber material are applied that the configura tion of the adhesive strands a two-dimensional grid works results under tensile stress and suspension elastic stretching and resetting the Glue strand configuration allowed.
Der Klebstoffauftrag kann beispielsweise durch Mehrfach düsen erfolgen, so daß senkrecht zur Laufrichtung der Materialbahnen entstehende Streifen gebildet sind. Es kann auch durch entsprechend gegeneinander bewegbare Düsen ein waffelartiger oder gitterartiger Auftrag er folgen oder auch eine rechteckförmige Struktur. 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 Heißkle ber verarbeitet werden können.The application of adhesive can, for example, by multiple nozzles are made so that perpendicular to the direction of the The resulting strips of material are formed. It can also by correspondingly movable against each other A waffle-like or lattice-like application follow or even a rectangular structure. Not it should also be excluded that in the marginal area of a fabric that is used, for example, to Panty liners, sanitary pads or the like processed to become, there is a higher adhesive density than in Middle range. It is always about adhesives that stay elastic at room temperature and as a hot glue can be processed.
Ausführungsformen der Erfindung sind in der Zeichnung dargestellt. Die Figuren der Zeichnung zeigen:Embodiments of the invention are in the drawing shown. The figures in the drawing show:
Fig. 1 eine Ausführungsform einer mehrschichti gen Materialbahn in auseinandergezogener Darstellung; Figure 1 shows an embodiment of a multilayer material web in an exploded view.
Fig. 2 schematisiert eine Herstellungsphase einer mehrschichtigen Materialbahn. Fig. 2 schematically shows a manufacturing phase of a multi-layer material web.
In Fig. 1 sind zwei Vliesbahnen 1, 2 dargestellt, von denen die eine, untere Vliesbahn 2 mit Hilfe eines beheizbaren Tiefdruckwerkes (nicht dargestellt) mit einer Konfiguration von Klebstoffsträngen 3 beschichtet ist. Die Klebstoffstränge haben etwa eine Dicke von 0,1 bis 1,5 mm bei einer Breite der Vliesstoffbahn 1; 2 von etwa 50 mm. Wie erkennbar, sind die Vliesstoffstränge so gelegt, daß sie in Sinuskurven verlaufen, wobei sie sich in ihren Scheiteln 4 jeweils überlappen oder berühren, so daß eine waffelartige Konfiguration 5 entsteht. Wird in Querrichtung Q an dem Flächengebilde, das aus den Klebstoffsträngen und den beiden Vliesstoffbahnen 1, 2 besteht, gezogen, so ziehen sich auch die Klebstoffstränge auseinander. Da sie jedoch aus bei Raumtemperatur elastischen Thermoplasten bestehen, erfolgt nach Ablassen der Zugbeanspruchung eine Rückstellung aufgrund der Flexibilitätseigenschaften der Klebstoff-Konfiguration.In Fig. 1, two non-woven webs 1, 2, of which the one, lower nonwoven web (not shown) 2 by means of a heated gravure work is coated with a configuration of adhesive strands. 3 The adhesive strands have a thickness of approximately 0.1 to 1.5 mm with a width of the nonwoven web 1 ; 2 of about 50 mm. As can be seen, the nonwoven strands are laid out in such a way that they run in sinus curves, each overlapping or touching in their apex 4 , so that a waffle-like configuration 5 is produced. If the sheet structure consisting of the adhesive strands and the two nonwoven webs 1 , 2 is pulled in the transverse direction Q, the adhesive strands also pull apart. However, since they consist of thermoplastics that are elastic at room temperature, a reset occurs after releasing the tensile stress due to the flexibility properties of the adhesive configuration.
Das Aufbringen kann auch mit einen Druckverfahren, bei spielsweise Flexodruck oder Siebdruck erfolgen. The application can also be done using a printing process for example, flexographic printing or screen printing.
Gemäß Fig. 2 wird ein Verfahren gewählt, bei dem zwei Vliesstoffstränge 1, 2, die über ein Band erzeugt worden sind, über Umlenkrollen 11, 12 herangeführt werden. Über zwei Arbeitswalzen 13, 14 werden die beiden Bahnen 1, 2 zusammengeführt, wobei mit Hilfe von mehreren quer zur Bahnrichtung liegenden Düsen 15 ein Klebstoffstrang 16 direkt von oben in den Spalt der beiden zusammengeführ ten Bahnen 1, 2 aufgelegt wird.According to FIG. 2, a method is selected in which two nonwoven strands 1 , 2 , which have been produced via a belt, are brought up via deflection rollers 11 , 12 . About two work rolls 13 , 14 , the two webs 1 , 2 are merged, with the help of several nozzles 15 lying transversely to the web direction, an adhesive strand 16 is placed directly from above into the gap of the two merged webs 1 , 2 .
Die vergrößerte Darstellung im unteren Teil der Fig. 2 zeigt, daß Klebstoffstränge vorhanden sind, die im Schnitt jeweils als Kreise 16 erscheinen. Der Klebstoff wird jeweils als Heißkleber in dünnflüssigem, erhitztem Zustand aufgebracht und erstarrt im Laufe des weiteren Verfahrens zu einem elastischen Strang, mit dem mehr schichtige, elastische Flächengebilde hergestellt werden können, die aus wenigstens zwei Bahnen aus porösem Faser material, insbesondere Non-Woven aus Polyethylen, Poly propylen oder anderen Polyolefinen zusammengeführt werden können, so daß ein hochelastisches Flächengebilde entsteht.The enlarged view in the lower part of FIG. 2 shows that there are strands of adhesive which appear as circles 16 on average. The adhesive is applied in each case as a hot melt adhesive in a thin, heated state and solidifies in the course of the further process to form an elastic strand, with which multilayer, elastic sheet-like structures can be produced, which consist of at least two webs of porous fiber material, in particular non-woven Polyethylene, poly propylene or other polyolefins can be brought together, so that a highly elastic fabric is created.
Mit dem vorgenannten Verfahren lassen sich "atmungsfähi ge" Flächengebilde herstellen, wie sie insbesondere für Hygieneartikel, wie Slipeinlagen, Windeln, Inkontinenz einlagen und dergleichen benötigt werden. Durch die ent sprechende Abstimmung der Vliesdicke und Saugfähigkeit lassen sich diese Eigenschaften weitgehend steuern, wäh rend die Elastizität durch die besondere Mittelschicht gewährleistet ist. 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 aforementioned method, "breathable "Manufacture fabrics as they are especially for Hygiene articles, such as panty liners, diapers, incontinence deposits and the like are needed. Through the ent appropriate coordination of the fleece thickness and absorbency these properties can be largely controlled, weh elasticity thanks to the special middle layer is guaranteed. Production can also be high Speed take place because of heated printing cylinders, with to which a hot melt thermoplastic can be applied, are known with high rotational speed work. The adhesive can be made of SBS, for example Metallocene polyolefins or the like exist.
