ABSTRACT:
There is described an airbag fabric made of a synthetic yarn. The synthetic yarn is a high-tenacity polyester filament yarn having filaments of less than 4 dtex and a yarn count within the range from 250 to 550 dtex. The fabric itself, in contrast to the conventional polyamide fabrics, is uncoated and is preferably made by weaving 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 low air permeability, low fabric weight, low fabric thickness and high fabric strength.
