Abstract
Description
Für Bekleidungsstücke verwendete wasserdichte Materialien haben in der Vergangenheit den großen Nachteil aufgewiesen, dass sie auch für Wasserdampf undurchlässig waren, sodass die vom Körper produzierte Feuchtigkeit in Form von Schweiß, der einen wichtigen Mechanismus zur Temperaturregulierung des Körpers darstellt, nicht oder lediglich unzureichend abgeführt werden konnte. Der Mangel an Schweißabfuhr führt zu einer Kondensatbildung an der Innenseite des Bekleidungsstücks, sodass dieses nass ist und dem Träger ein unangenehmes Gefühl vermittelt. Die Verwendung von atmungsaktiven Stoffen hat zwar in der Regel die Verdunstung des anfallenden Schweißes ermöglicht; gleichzeitig waren diese Bekleidungsstücke jedoch nicht in der Lage, Wasser von der Haut fernzuhalten, da sie nicht gleichzeitig wasserdicht und atmungsaktiv waren.Used for clothing waterproof materials have the great disadvantage in the past exhibited that too for her Impermeable to water vapor were, so the body produced moisture in the form of sweat, which is an important mechanism for temperature regulation of the body represents, not or only insufficiently dissipated could. The lack of welding discharge leads to Condensation on the inside of the garment, so this is wet and the wearer an unpleasant feeling taught. Although the use of breathable fabrics has in usually allows the evaporation of the resulting sweat; were at the same time these clothes However, they are unable to keep water out of the skin as they are not waterproof and breathable at the same time.
Zur Beseitigung dieses Nachteils wurden PTFE-Membranen entwickelt, die mit Textilien, zumeist Polyester oder Polyamid, dauerhaft und flexibel verklebt bzw. auflaminiert werden. Das dadurch entstehende Verbundmaterial weist eine mikroporöse, luftdurchlässige Polymerschicht auf, die mit einem wasserdampfdurchlässigen Polymer versehen sind. Die Membran weist Poren auf, die etwa 20.000 mal kleiner als Wassertropfen sind. Sie ist daher dicht gegen Wasser und Wind; Körperfeuchtigkeit kann jedoch in Form von Wasserdampf durch die Membran hindurchtreten/diffundieren. Die Membran ist folglich atmungsaktiv.to Eliminating this disadvantage, PTFE membranes have been developed which with textiles, mostly polyester or polyamide, permanently and flexibly glued or laminated. The resulting composite material has a microporous, air-permeable polymer layer on, which are provided with a water vapor permeable polymer. The Membrane has pores about 20,000 times smaller than water droplets are. It is therefore tight against water and wind; body moisture however, can pass / diffuse through the membrane in the form of water vapor. The membrane is thus breathable.
Die Diffusion des Wasserdampfes durch die Membran erfolgt durch den Druckunterschied zwischen der unter der Bekleidung herrschenden Temperatur und der Umgebungstemperatur. Soweit die Temperatur unter dem Bekleidungsstück deutlich größer als die Umgebungstemperatur ist, erfolgt aufgrund des Bedürfnisses der Natur, ein Gleichgewicht herzustellen, ein Druckausgleich durch die Membran, bei der der Wasserdampf nach außen abgeführt wird.The Diffusion of water vapor through the membrane takes place through the Pressure difference between the ruling under the clothing Temperature and ambient temperature. As far as the temperature is below the garment significantly larger than the ambient temperature is due to the need nature to balance, pressure equalization the membrane, in which the water vapor is discharged to the outside.
Bei den bekannten Membranen erfolgt über die gesamte Fläche des mehrschichtigen Materials/der Membran eine gleichmäßige Diffusion des Wasserdampfes. Folglich besteht nur durch Verwendung unterschiedlicher Membranen innerhalb eines Bekleidungsstücks die Möglichkeit, unterschiedliche Diffusionseigenschaften innerhalb der Membran zu realisieren. Durch die somit erforderliche Kombination verschiedener Membrane ist die Herstellung eines solchen Bekleidungsstücks aufwendig und damit teuer.at the known membranes via the the whole area of the multilayer material / membrane uniform diffusion of water vapor. Consequently, only by using different Membranes within a garment have the ability to have different diffusion properties to realize within the membrane. By thus required Combination of different membranes is the production of such garment consuming and therefore expensive.
Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, eine wasserdichte und wasserdampfdurchlässige Membran bereitzustellen, die ohne Kombination verschiedener Materialien in Abhängigkeit von den Anforderungen Bereiche unterschiedlicher Diffusionseigenschaften bereitstellt. Gemäß der Erfindung wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst.Here The invention aims to remedy this. The invention is the task underlying, a waterproof and water vapor permeable membrane to provide that without combining different materials dependent on provides areas of different diffusion properties from the requirements. According to the invention This object is achieved by the features of claim 1.
Mit der Erfindung ist eine wasserdichte und wasserdampfdurchlässige Membran geschaffen, welche Bereiche unterschiedlicher Diffusionseigenschaften bereitstellt, ohne dabei unterschiedliche Materialien miteinander kombinieren zu müssen. Auf diese Weise ist es möglich, das Material auf die jeweiligen Bedürfnisse anzupassen. So besteht beispielsweise bei Kleidungsstücken die Möglichkeit, im Bereich stärkeren Schweißanfalls einen Abschnitt mit verbesserten Diffusionseigenschaften anzuordnen, die benachbarten Abschnitte jedoch nur mit üblichen Diffusionseigenschaften zu versehen.With The invention is a waterproof and water vapor permeable membrane created, which areas of different diffusion properties providing without different materials to each other to combine. In this way it is possible to adapt the material to the respective needs. That is how it is for example, with garments the possibility, in the area stronger welding attack to arrange a section with improved diffusion properties, the adjacent sections but only with conventional diffusion properties to provide.
