Abstract
Industrial fabrics have controlled air permeability <120 l/dm.sup.2 .times. min and a very good ageing resistance. The air permeability value does not change by more than 15% in the ageing test. This fabric can be made by adapting production conditions for weaving, wet processing, and in particular, hot air treatment. The process is particularly suited for manufacturing air bag fabrics.
