Dadurch wird ein mehrschichtiges Flächengebildti geschaffen, das »atmet«, wobei jedoch die wellenbildende Eigenschaft aufrechterhalten bleibt.This creates a multilayer sheet created that "breathes", but the wave-forming property is retained.
Die Fläche des Saugvlieses, welches saugfähig ist oder saugfähig gemacht ist, kann z, B, in an sich bekannter Weise metallisiert sein, sofern dies für medi' zinische oder hygienische Zwecke, z,B, als Wundabdeckung, zweckmäßig sein sollte.The surface of the absorbent fleece which is absorbent or is made absorbent can, for example, be known per se Be metallized if this is necessary for medi ' sanitary or hygienic purposes, e.g. as a wound cover, should be appropriate.
In Abhängigkeit von dem Verwendungszweck des vorgeschlagenen mehrschichtigen Flächengebildes kann auch die wellenbildende Zellglasschicht in Form einer mehrschichtigen Zwischenschicht ausgebildet sein, sofern dies aus mechanischen oder aus anderen Gründen sich als erwünscht erweisen sollte.Depending on the intended use of the proposed multilayer sheet The wave-forming cell glass layer can also be designed in the form of a multilayer intermediate layer if this should prove to be desirable for mechanical or other reasons.
Zur Erzielung eines gewünschten Kühleffektes, insbesondere auf Wunden, läßt sich das vorgeschlagene mehrschichtige Flächengebilde in an sich bekannter Weise mit einer dunklen, vorzugsweise violetten Farbe ausrüsten. Es ist auch die Möglichkeit gegeben, lediglich die wellenbildende Zellglasschicht ao bzw. -schichten mit einer solchen dunklen, vorzugsweise violetten Farbe auszurüsten.To achieve a desired cooling effect, especially on wounds, the proposed multilayer sheet-like structure in a manner known per se with a dark, preferably violet one Equip paint. It is also possible to use only the wave-forming cell glass layer ao to equip or layers with such a dark, preferably violet color.
Zur Fertigung eines Versuchsmodells geht man z. B. folgendermaßen vor: Ein durchfeuchtetes Faservlies, beispielsweise von 10 χ 12 cm Größe, as wird auf eine Glasplatte gelegt, darauf mit einer an den Kanten etwas überstehenden Zellglasfolie faltenfrei verhaftet. Auf diese glatte Zellglasfolie wird ein weiteres Faservlies faltenfrei angelagert. Man läßt diese Faservlies-Zellglas-Faservlies-Kombination an der Luft auf einer saugenden Unterlage trocknen. Nach Beendigung des Trocknungsprozesses läßt sich folgender Versuch anstellen:To produce a test model you go z. B. Proceed as follows: A soaked Fiber fleece, for example 10 χ 12 cm in size, as is placed on a glass plate, on top of which with a cellophane film protruding slightly at the edges, without creases arrested. Another fiber fleece is deposited on this smooth cellulose film without creases. One lets Dry this fiber fleece, cellulose glass fiber fleece combination in the open air on an absorbent pad. After the drying process has ended, the following experiment can be carried out:
Man beschickt eine genügend große Glas- oder eine andere völlig glatte Platte mit je einer Wasserpfütze von etwa 1,0 ml. Belegt man den einen Wasserbereich mit einem Faservlies allein, bleibt dieses wie angek'atscht auf der Oberfläche auch nach Hochstellen der Platte haften. Geht man in gleicher Weise mit einem mehrschichtigen Flächengebilde nach der Erfindung vor, fällt dieses nach Hochstellen der Platte nach kurzer Zeit von dieser ab. Man kann diesen Versuch wiederholen, wobei das Kontrollvlies immer noch haften bleibt, während das mehrschichtige Flächengebilde nach der Erfindung jedesmal nach Hochstellen der Platte abfällt. Man kann dabei die zur Ablösung führenden Bewegungsvorgänge der genannten Kombination beobachten.A sufficiently large glass plate or another completely smooth plate is filled with a puddle of water each of about 1.0 ml. If one area of water is covered with a fiber fleece alone, this remains Adhere to the surface like chattered, even after the plate has been raised. If you go in the same Way before with a multilayer sheet-like structure according to the invention, this falls after standing up the plate from this after a short time. You can repeat this experiment using the control fleece still adheres, while the multilayer sheet according to the invention every time falls after the plate is raised. One can see the movement processes leading to the replacement of the observe the combination mentioned.
