Abstract

Es wird ein Aufgussbeutel beschrieben, welcher eine Lage aus einem Vliesstoff aus Bikomponenten-Fasern und/oder -filamenten aus einer hochschmelzenden und einer niedrig schmelzenden Komponente umfasst, wobei die hochschmelzende Komponente ein Polyester umfasst. Probleme bei der Konfektionierung des Vliesstoffes werden dadurch vermieden, dass die niedrigschmelzende Komponente ein ebenfalls hochschmelzendes Polymer mit einem Schmelzpunkt ≥ 200 °C umfasst.There is described an infusion bag comprising a layer of a nonwoven web of bicomponent fibers and / or filaments of a refractory and a low melting component, wherein the refractory component comprises a polyester. Problems in the fabrication of the nonwoven fabric are avoided by the fact that the low-melting component comprises a likewise high-melting polymer with a melting point ≥ 200 ° C.
