Abstract
Uncoated fabrics for the production of airbags, particularly said airbags. There fabrics are thermally stable and set to a specific air permeability via the linear density-dependent choice of the numbers of threads and via a relaxation in a wet process. The fabric is constructed of yarns of polytetramethyleneadipamide having a yarn linear density of 200-500 dtex and a filament linear density <7 dtex. The fabrics produced have an air permeability <100 l/dm.sup.2 xmin. They offer security against thermal failure when used in manufacturing airbags.
