Abstract
Description
SchichtkörperLaminated body
Die Erfindung betrifft einen Schichtkörper, bei dem zwei Außenlagen aus gas-, insbes. luftdurchlässigem Material einer Wirkstoffschicht, vorzugsweise pflanzlicher Art, z. B. aus Heilkräutern, anliegen und mit dieser verbunden sind. The invention relates to a laminated body in which two outer layers made of gas-permeable, especially air-permeable material of an active ingredient layer, preferably vegetable type, e.g. B. from medicinal herbs, fit and are connected to this.
Bei Schichtkörpern dieser Art (CH-PS 69075) wurde es bekannt, als Außenlagen Stoffiagen zu verwenden und die Verbindung durch Vernähen, mittels "Steppstich" herzustellen. In laminated bodies of this type (CH-PS 69075) it became known as Use outer layers of fabric and the connection by sewing, using "lockstitch" to manufacture.
Hierbei wird durch eine Nähnadel ein Nähgarn durch die Außenlagen und die Zwischenschichte geführt. Hierbei besteht ein relativ großer Zwischenraum zwischen im Schichtkörper benachbarten, den Schichtkörper durchsetzenden Nähgarnen. Bei zu kleinem Abstand der Fäden würde der Schichtkörper zu steif und brettähnlichen Charakter erhalten. Der Wirkstoff kann hiebei nur in relativ bescheidenem Ausmaß zwischen den Außenlagen gehalten werden (Gefahr des Verrutschens), bzw. kann nur grobfasriges Material als Wirkstoff eingesetzt werden, dessen Oberfläche bescheiden ist, so daß die Wirkstoffabgabe bei Anwendung des bekannten Schichtkörpers nicht allzu groß sein kann.A sewing needle is used to run a sewing thread through the outer layers and led the intermediate layer. There is a relatively large gap here between sewing threads which are adjacent in the laminate and penetrate the laminate. If the distance between the threads is too small, the laminate would be too stiff and board-like Get character. The active ingredient can only be used to a relatively limited extent be held between the outer layers (risk of slipping), or can only Coarse-fibred material can be used as an active ingredient, the surface of which is modest is, so that the drug release when using the known layered body is not can be too big.
Es wurde auch bereits bekannt (DE-AS 11 90 608), als Deckschicht eine Kunststoffolie zu verwenden, die mit Perforationen versehen ist. Die Durchlässigkeit ist hier bescheiden, so daß die Wirksubstanz schwer aus dem Inneren heraus kann. It was also already known (DE-AS 11 90 608), as a top layer to use a plastic film with perforations. The permeability is modest here, so that it is difficult for the active substance to come out of the inside.
Der Perforationsdichte sind im Hinblick auf die notwendige Festigkeit Grenzen gesetzt, so daß auch die Möglichkeit, durch Anbringen einer größeren Anzahl von Perforationen die Durchgängigkeit der Deckschicht zu verbessern, nur eine beschränkte ist.The perforation density are in view of the necessary strength Limits are set, so that also the possibility of attaching a larger number of perforations to improve the patency of the top layer is only limited is.
Der Erfindung liegt nun die Aufgabe zugrunde, einen Schichtkörper der eingangs erwähnten Art so weiter zu bilden, daß er eine verbesserte Gas- b#w Luftdurchlässigkeit bei hoher Festigkeit aufweist und der Wirkstoff einwandfrei zwischen den Außenlagen gehalten, somit gegen Verrutschen gesichert ist, selbst wenn Wirkstoffe mit im Vergleich zu ihrem Volumen großer Oberfläche verwendet werden, wobei auch ein Tragen des Schichtkörpers unter der Kleidung möglich sein und eine großflächige Auflage erreichbar sein soll. Erreicht wird dies bei einem Schichtkörper der eingangs erwähnten Art, wenn gemäß der Erfindung die Außenlagen von einem Faservlies oder Nadelfilz gebildet sind und wenn die Außenlagen miteinander unter Durchsetzen der anliegenden Wirkstoffschicht durch Vernadeln verbunden sind. Hiebei werden Fasern aus einer Vlies-oder Filzschicht mittels Nadeln durch den Wirkstoff hindurch und in die zweite Schicht eingestoßen. Es entsteht dabei auch eine Verdichtung des Schichtkörpers. Die zwischen den Außenlagen befindliche Schicht wird hiebei von- Fasern, die von den Nadeln aus der Vlies- oder Filzschicht, in der sie war, im wesentlichen waagrecht liegen, mitgenommen wurden, in Richtung der Nadelbewegung (bevorzugt senkrecht zur Außenlage) durchsetzt. Der erfindungsgemäß gestaltete Schichtkörper besitzt wesentlich bessere Durchlässigkeit als ein Schichtkörper, dessen Außenlagen von Stoffen gebildet sind. Die Vielzahl der den Schichtkörper durchsetzenden Fasern erlaubt die Anwendung von fein geschnittenen bzw. zerkleinerten Wirkstoffen, gegebenenfalls sogar in Pulverform, ohne Gefahr des Verrutschens. Die Wirkstoffabgabe kann hiedurch, bedingt durch die große Oberfläche der Wirkstoffe, die in dem Raum zwischen den Außenlagen aus Faservliesen oder Nadelfilzen untergebracht werden kann, erhöht werden. The invention is now based on the object of a laminated body of the type mentioned above so that he can improve gas b # w Has air permeability with high strength and the active ingredient is flawless held between the outer layers, thus secured against slipping, self if active substances with a large surface area compared to their volume are used, it is also possible to wear the laminated body under clothing and one large area should be achievable. This is achieved with a layered body of the type mentioned at the outset, if, according to the invention, the outer layers are made of a fiber fleece or needle felt and when the outer layers are interpenetrating the adjacent active ingredient layer are connected by needling. This creates fibers from a fleece or felt layer by means of needles through the active substance and pushed into the second layer. This also results in a compression of the layered body. The layer located between the outer layers is made up of fibers that of the needles from the fleece or felt layer in which it was, essentially horizontally lying, were taken along, in the direction of the needle movement (preferably perpendicular to the Outer layer) interspersed. The laminated body designed according to the invention has essential better permeability than a layered body, the outer layers of which are made up of fabrics are. The large number of fibers penetrating the laminate allows the application of finely chopped or comminuted active ingredients, possibly even in powder form, without the risk of slipping. The release of the active ingredient can thereby, due to the large surface area of the active ingredients in the space between the outer layers of nonwovens or needle felting can be accommodated.
Das durch den Wirkstoff durchgestoßene Fasermaterial erhöht die Saugfähigkeit und bringt auch geringste Feuchtigkeit zu einer Vielzahl von Wirkstoffpartikeln, wogegen Nähgarn durch seine kompakte Beschaffenheit wesentlich weniger saugfähig ist und nur an vergleichsweise ganz wenige Wirkstoffteile herankommt. The fiber material penetrated by the active ingredient increases the absorbency and brings even the slightest moisture to a large number of active ingredient particles, whereas sewing thread is much less absorbent due to its compact nature and only a comparatively small number of active ingredients can be accessed.
Anderseits bewirken die durchgestoßenen Fasern in Verbindung mit den Außenlagen, daß aufgenommene Feuchtigkeit auch wieder besonders rasch ablüftet und die Wirkstoffe trocknen. On the other hand, cause the pierced fibers in conjunction with the outer layers that absorbed moisture evaporates particularly quickly and dry the active ingredients.
Dies ist von Wichtigkeit, weil sonst, vor allem bei längerer Anwendungsdauer, ein Befall der Wirkstoffe mit Bakterien, Pilzen etc. zu befürchten ist.This is important because otherwise, especially with longer periods of use, an infestation of the active ingredients with bacteria, fungi, etc. is to be feared.
Ein erfindungsgemäß ausgestalteter Schichtkörper kann problemlos auch unter der Kleidung getragen werden, da der Wirkstoff gleichmäßig verteilt und rutschsicher gehalten ist. A laminated body designed according to the invention can be used without problems can also be worn under clothing, as the active ingredient is evenly distributed and Is held non-slip.
Große Körpe#rflächen können mit erfindungsgemäßen Schichtkörpern bedeckt werden, Eine Applikation über längere Zeitspannen wird solcherart ermöglicht. Sind die Fasern, aus denen das Vlies bzw. der Nadelfilz besteht, besonders saugfähig, nehmen die Fasern körpereigene Feuchtigkeit auf und übertragen sie auf die Wirkstoffe, wodurch deren Wirkung erhöht wird. Gleichzeitig bleibt jedoch der bedeckte Körperteil troc-ken. Genauso kann der erfindungsgemäße Schichtkörper durch sein Vermögen, Flüssigkeiten aufzunehmen und bis zu einer bestimmten Grenze zu speichern, auch für feuchte Auflagen, Wickel, Bandagen etc.Large body surfaces can be covered with laminated bodies according to the invention Application over longer periods of time is made possible in this way. Are the fibers that make up the fleece or needle felt are particularly absorbent, the fibers absorb the body's own moisture and transfer it to the active ingredients, whereby their effect is increased. At the same time, however, the covered part of the body remains dry. The laminated body according to the invention can in exactly the same way, due to its capacity, liquids record and store up to a certain limit, also for damp conditions, Wraps, bandages, etc.
verwendet werden, wobei die Wirkung der Wirkstoffe verstärkt wird. Angewendet kann solcherart ein erfindungsgemäßer Schichtkörper im trockenen Zustand vorwiegend untertags unter der Bekleidung, in feuchtem Zustand jedoch vorwiegend bei Bettlägerigkeit, jeweils in anwendungstechnisch geeigneter Form. Die Anwendung kann beispielsweise in Form von Schuheinlegesohlen, Damenbinden, Nierenbinden, Blasenbinden, Gelenkschützern, Bandagen usw. erfolgen. Erfindungsgemäß ausgebildete Schichtkörper bringen weiters den Vorteil, daß dem lebenden Körper bei voller Atmungsaktivität die eigene Wärme zum Großteil erhalten bleibt und damit die Auswirkung der Wirkstoffe erhöht wird. Grundsätzlich können erfindungsgemäße Schichtkörper auch in Verbindung mit Heizelementen wie Wärmeflaschen, Heizkissen, Heizdecken usw. verwendet werden, je nach Bedarf und Möglichkeit sowohl in trockenem als auch in feuchtem Zustand.can be used, whereby the effect of the active ingredients is enhanced. Such a layered body according to the invention can be used in the dry state predominantly during the day under clothing, but predominantly when wet if bedridden, in each case in an application-technically appropriate form. The application can for example in the form of shoe insoles, sanitary napkins, kidney pads, bladder pads, Joint protectors, bandages, etc. take place. Laminated bodies designed according to the invention furthermore bring the advantage that the living body is fully breathable the own heat is largely retained and with it the effect of the active ingredients is increased. In principle, laminates according to the invention can also be used in conjunction be used with heating elements such as hot water bottles, heating pads, electric blankets, etc. depending on requirements and possibilities, both in dry and in wet condition.
Als Wirkstoffe können etwa auch Blüten, Blätter, Rinden und Wurzeln eingesetzt werden. Blossoms, leaves, bark and roots can also be used as active ingredients can be used.
In weiterer Ausgestaltung des Erfindungsgegenstandes ist 2 vorgesehen, daß von den Außenlagen pro cm Fläche 120 - 160 Fasern in die anliegende Wirkstoffschicht ragen. Hiedurch ergeben sich besonders günstige Effekte, was den Saugeffekt und die Festigkeit sowie die Nachformbarkeit von Körperformen anlangt. In a further embodiment of the subject matter of the invention, 2 is provided, that of the outer layers per cm area 120 - 160 Fibers in the adjacent Layer of active ingredient protrude. This results in particularly favorable effects, which the Suction effect and the strength and reshaping of body shapes.
Gemäß der Erfindung kann weiters vorgesehen sein, daß zwischen den beiden Außenlagen mindestens eine weitere Lage eines Faservlieses oder Nadelfilzes angeordnet ist, die beidseits am Wirkstoff anliegen und mit diesem durch Vernadeln verbunden sind. Solcherart ist es möglich, Matten mit relativ hohem Wirkstoffgehalt herzustellen, die ausreichende Festigkeit und Saugfähigkeit besitzen. Bevorzugt können zwei durch eine Zwischenschicht aus Faservlies oder Nadelfilz getrennte Wirkstofflagen zur Anwendung kommen. Hierbei können wahlweise auch Nadelfilzlagen mit Vlieslagen in beliebiger Reihenfolge jeweils mit Wirkstofnwi schenschichten miteinander vernadelt werden. According to the invention it can further be provided that between the two outer layers at least one further layer of a fiber fleece or needle felt is arranged, which rest on both sides of the active ingredient and with this by needling are connected. In this way it is possible to produce mats with a relatively high active ingredient content produce that have sufficient strength and absorbency. Preferred can have two layers of active substance separated by an intermediate layer made of fiber fleece or needle felt come into use. Here, needle felt layers with fleece layers can optionally also be used needled together in any order, each with active substance layers will.
Der Wirkstoff zwischen den Außenlagen kann auch durch Fasern, die aus beiden Außenlagen stammen, durchsetzt sein. The active ingredient between the outer layers can also be through fibers that come from both outer layers, be interspersed.
Das Nadeln erfolgt in diesem Fall von beiden Seiten her.In this case, needling is done from both sides.
Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise näher erläutert. Es zeigen, Fig. 1 in schaubildlicher Darstellung einen zu einer Rolle gewickelten erfindungsgemäßen Schichtkörper, und Fig. 2 einen Ausschnitt aus einem erfindungsgemäßen Schichtkörper, in schaubildlicher Darstellung, jedoch in einem gegenüber dem Maßstab der Fig. 1 vergrößertem Maßstab. The invention is illustrated below with reference to the drawing, for example explained in more detail. 1 shows a diagrammatic representation one to one Roll of wound laminates according to the invention, and FIG. 2 shows a section a laminated body according to the invention, in a diagrammatic representation, but in a compared to the scale of FIG. 1 enlarged scale.
Der erfindungsgemäße Schichtkörper besitzt in der beispielweisen Ausführungsform zwei Außenlagen 1, 2 aus gas-, insbes. luftdurchlässigem Material und eine dazwischenliegende Wirkstoffschicht 3. Als Wirkstoffe können Heilpflanzen, Kräuter, Blüten, Blätter, Rinden und Wurzeln, vor allem in fein zerkleinerter Form, verwendet werden. Die Außenlagen 1, 2 bestehen aus einem Faservlies oder einem Nadelfilz. In einem solchen Material liegen die Fasern wirr, im wesentlichen horizontal. Die Außenlagen 1, 2 sind miteinander unter Durchsetzen der anliegenden Wirkstoffschicht 3durch Vernadeln verbunden. Beim Vernadeln nimmt jede Nadel beim Durchstoßen der betreffenden von einem Faservlies oder Nadelfilz gebildeten Außenlage 1 und/oder 2 eine oder mehrere Fasern mit. Werden von Nadeln Fasern senkrecht durch das Vlies durchgestoßen, kommen diese durchgestoßenen Fasern senkrecht zu den nicht 2 durchgestoßenen Fasern zu liegen. Da im Mittel pro cm 120 -160 Durchstiche erfolgen, wird das Vlies, oder werden mehrere übereinander liegende Vliese (Außenlagen und Zwischenschichten) durch die senkrecht mitgenommenen Fasern durchsetzt und zu einer Art "Nadelfilz" verdichtet. The laminate according to the invention has, for example Embodiment two outer layers 1, 2 made of gas, especially air-permeable material and an intermediate layer of active ingredients 3. Medicinal plants, Herbs, flowers, leaves, bark and roots, especially in finely chopped form, be used. The outer layers 1, 2 consist of a fiber fleece or a needle felt. In such a material the fibers are tangled, essentially horizontal. the Outer layers 1, 2 are mutually interpenetrating with the adjacent layer of active ingredient 3by needling tied together. When needling, each needle takes Piercing the relevant outer layer formed by a fiber fleece or needle felt 1 and / or 2 with one or more fibers. Fibers run vertically through needles pierced the fleece, these pierced fibers come perpendicular to the not 2 pierced fibers to lie. Since there are 120-160 punctures per cm on average, becomes the fleece, or several fleeces lying one on top of the other (outer layers and Intermediate layers) penetrated by the vertically entrained fibers and become one Type "needle felt" compacted.
Aus Fig. 2 ist der Verlauf dieser nach dem Durchnadeln im wesentlichen vertikal verlaufenden Fasern 4 angedeutet. Die in den Außenlagen 1, 2 wirr, jedoch im wesentlichen horizontal liegenden Fasern sind mit 4' bzw. 4" bezeichnet. From Fig. 2, the course of this is essentially after needling vertically extending fibers 4 indicated. The ones in the outer layers 1, 2 are confused, however Fibers lying essentially horizontally are denoted by 4 'and 4 ", respectively.
In Abänderung der dargestellten Ausführungsform können auch mehrere, jeweils durch zwischengelegte Faservliese oder Nadelfilze voneinander getrennte Wirkstoffschichten mit den Außenlagen 1, 2 zu einem Schichtkörper vernadelt werden. Leerseite In a modification of the embodiment shown, several, each separated from one another by interposed nonwovens or needle felts Active ingredient layers are needled with the outer layers 1, 2 to form a laminate.
