Zusammenfassung: | The invention relates to a multilayer, composite, fleece material having a core layer and at least one cover layer attached to the core layer, where the at least one cover layer is needled with the core layer such that fibers of the at least one cover layer protrude into the core layer. The multilayer, composite, fleece material is intended for use in the manufacture of interior panels of vehicles and to have improved mechanical properties, low thermal conductivity, very low tendency to produce emissions, and good acoustic properties when used for that purpose, as well as enable its inexpensive manufacture. The cover layer and the fibers protruding from the cover layer into the core layer are at least partially firmly bonded to the core layer, where the core layer contains amorphous, bicomponent fibers having a component with a lower melting point and a component with a higher melting point, and the at least one cover layer contains crystalline, bicomponent fibers having a component with a lower melting point and a component with a higher melting point. The invention also relates to a method for manufacturing a multilayer, composite, fleece material and a method for manufacturing a molded component, for example, an automobile headlining, from the composite, fleece material. |
