Abstract
Uncoated, tightly woven, synthetic filament yarn fabric for manufacturing an air bag. The fabric is manufactured from polyamide yarns having a filament linear density of less than 4 dtex. The air permeability of this fabric is <10 l/dm.sup.2 .multidot.min and its specific stiffness is <1.0.times.10.sup.-2.
Claims10
An uncoated, tightly woven, synthetic filament yarn fabric for manufacturing an air bag, wherein the yarn used to construct the fabric is a polyamide yarn having a filament linear density of less than 4 dtex and a yarn linear density of 200-600 dtex, and wherein said fabric has a specific stiffness of <1.0.times.10.sup.-2 and an air permeability <10 l/dm.sup.2 .multidot.min, said air permeability obtained by shrinking the fabric in a wet process.
