Document Type and Number:
WIPO Patent Application WO/2010/120107
Kind Code:
A2
Abstract:
The present invention relates to a polyester yarn that can be used for airbag fabric, and particularly, to a polyester yarn for an airbag with an initial modulus of 40 to 100 g/d, which, at room temperature, has a measured elongation of 0.5% or more under 1.0 g/d stress, an elongation of 4.3% or more under 4.0 g/d stress, and an elongation of 7.5% or more under 7.0 g/d stress, to a method for manufacturing same, and to an airbag fabric manufactured using same. The polyester yarn of the present invention has a significantly reduced degree of stiffness to give excellent mechanical/physical properties, in order to provide good storability, structural integrity, and air-tightness, as well as to securely protect passengers by minimizing the force of impact on the passengers when used as airbag fabric.
