Document Type and Number:
WIPO Patent Application WO/2011/162486
Kind Code:
A2
Abstract:
The present invention relates to fabric for an airbag, using a polyethylene terephthalate fiber, and more specifically, to fabric for an airbag with improved heat resistance and instantaneous thermal deformation prepared by preparing a polyethylene terephthalate fiber for an airbag by controlling the strength and elongation of a polyethylene terephthalate fiber and using the same, to replace known fabric for an airbag using yarns made of Nylon 66. The fabric for an airbag of the present invention, comprising a polyethylene terephthalate fiber prepared by spinning polyethylene terephthalate chips having an intrinsic viscosity of 0.8-1.3 dl/g, has a heat resistance of 0.45-0.65 seconds at 450 ℃ and a heat resistance of 0.75-1.0 seconds at 350 ℃.
