Abstract

Mehrschichtiges flüssigkeitsdichtes Vliesmaterial aus mindestens einer Spinnvlies-Schicht und einer Melt-Blown-Schicht, die durch Thermobonding miteinander verbunden sind. Das Ausgangsmaterial zur Herstellung der Schichten ist durch Polymere in Form von Granulat gebildet, welches zu einer Schmelzflüssigkeit verarbeitet wird, aus welcher die Fasern/Filamente zur Bildung der Schichten erzeugt werden. Die Fasern mindestens einer Schicht enthalten Additive, welche die Benetzungsfähigkeit der Faseroberfläche für Fllüssigkeiten herabsetzen, wobei die Additive im wesentlichen über den Faserquerschnitt verteilt sind.

Figure 00000001
Multi-layer, liquid-tight nonwoven material consisting of at least one spunbond layer and a melt-blown layer, which are bonded together by thermobonding. The starting material for the production of the layers is formed by polymers in the form of granules, which are processed into a melt liquid from which the fibers / filaments for forming the layers are produced. The fibers of at least one layer contain additives which reduce the wettability of the fiber surface for liquids, the additives being essentially distributed over the fiber cross section.
