Abstract

Provided is a fabric for an airbag using a polyethylene terephthalate fiber, and particularly, to a fabric for an airbag having enhanced thermal resistance and instantaneous thermal strain rate, which is manufactured using a polyethylene terephthalate fiber for an airbag manufactured by controlling the strength and elongation of the polyethylene terephthalate fiber to replace a conventional fabric for an airbag using a yarn formed of nylon 66. The fabric for an airbag including a polyethylene terephthalate fiber manufactured by spinning a polyethylene terephthalate chip having an intrinsic viscosity of 0.8 to 1.3 dl / g has thermal resistances of 0.45 to 0.65 seconds at 450° C., and 0.75 to 1.0 seconds at 350° C.

Description

technical field [0001] The present invention relates to fabrics for airbags using polyethylene terephthalate fibers, in particular, to fabrics for airbags having enhanced heat resistance and instantaneous thermal deformation The airbag manufactured using the strength and elongation of the polyethylene terephthalate fiber was manufactured using the polyethylene terephthalate fiber, thereby replacing the common airbag fabric using yarn formed of nylon 66. Background technique [0002] The airbag requires low air permeability characteristics to make it easy to rupture in the event of a car collision, and energy absorbency to avoid damage and burst of the airbag itself. In addition, for easier storage, properties related to the foldability of the fabric itself are required. Nylon 66 is generally used as a suitable fiber with the above properties. Recently, however, there has been increasing interest in fibers other than nylon 66 in order to save costs. [0003] Polyethylene t...
