Beschreibung
Zusammenfassung:	The present invention relates to a nonwoven structure comprising: (A) a scrim with a first surface and a second surface, the scrim having a basis weight of from about 8 gsm to about 200 gsm; (C) deposited on the first surface of the scrim, from about 1 gsm to about 40 gsm of a polymeric coating; and, optionally, (D) deposited on the second surface of the scrim from about 1 gsm to about 40 gsm of a second polymeric coating; a process for the production of a nonwoven structure; and a motorized vehicle having at least one barrier, the barrier being at least partially insulated by a nonwoven structure.
