Abstract

In a method of manufacturing uncoated industrial woven fabrics having specifically adjusted air permeability from synthetic fibers, after the synthetic fibers have been woven into a fabric the fabric is passed through an aqueous bath having a temperature of approximately 20.degree.-100.degree. C., then is passed through a drying zone. The woven fabric is allowed to shrink in the aqueous bath and in the subsequent drying zone to produce a woven fabric having a specific air permeability. The method is especially suitable for the manufacture of fabric used in air bags.
