Abstract: There is described a synthetic yarn fabric for the gas-releasing part of an airbag. The synthetic yarn is a synthetic high-tenacity multifilament yarn having a filament linear density of less than 4 dtex and a yarn count within the range from 250 to 550 dtex. The fabric itself is in a crepe or modified huckaback weave. In contradistinction to the conventional polyamide fabrics, it is uncoated and is preferably woven from unsized yarns. The fabric need not be calendered. It has been found that this fabric of fine-filament, high-tenacity polyester yarn, although uncoated, does meet the airbag fabric requirements such as readily preselectable air permeability, low fabric weight and low fabric thickness and also high fabric strength.
