Abstract
An overhead lining for vehicular inside roof linings of passenger cars is described, which is designed as self-supporting, integral shaped bowl. The overhead lining is made by compressing a mat of refuse nonwoven fabric, while exerting a pressure thereon at an elevated temperature. For this purpose, the refuse nonwoven fabric is made up of a mixture of at least 30 percent up to a maximum of 90 percent of partially stretched polyester fibers with parts of polyester high-bulk fibers, supplemented to 100 percent. The weight per unit area of the finished shaped bowl is between 600 and 1,200 grams per square meter, and the thickness is between 1 and 10 millimeters. The shaped bowl, on its one visual surface, is lined without an additional cement being used. The wall thickness of said shaped bowl may vary across its surface, and compaction of said shaped bowl, in the regions of its mounting elements, may be higher than in other regions.
