Abstract

See full text

: For technical fabrics which are preferably uncoated, 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 use is proposed 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/dm2xmin. They offer security against thermal failure, in particular when used for manufacturing airbags.
