Abstract
A method for the production of a porous, sound- and heat-insulating shaped element, in particular for lining of sound- and/or heat-emitting vehicle components, by shaping and solidifying a bonded fiber fabric made of natural fibers mixed with a thermoplastic binder in a press mold. The binder is crosslinked uniformly in all regions of the porous shaped element to produce a shaped element featuring a formaldehyde emission of less than 2 ppm due to the replacement of conventional resins with the thermoplastic binder.
