Title:
POLYETHYLENE TEREPHTHALATE FIBER FOR AIR BAGS
Document Type and Number:
WIPO Patent Application WO/2014/109514
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing PET filaments having excellent impulse energy absorption capabilities during a voltage surge. A PET fiber of the invention manufactured by spinning a PET chip having 0.8-1.3 dl/g of intrinsic viscosity in order to manufacture fabric for air bags, is capable of: being extended less than 4% when under an initial stress of 1.0 g/d at room temperature; having properties of a strength-deformation curve extended at least 8% when under a stress of 3.0 g/d; and having material properties of at least 30% elongation at break. The fiber has no greater than 30 eq/Ton of carboxyl end group (CEG) and no greater than 5 denier of single fiber fineness, and the PET fiber can be used to either warp or weft, or both warp and weft.
