Title:
POLYETHYLENE TEREPHTHALATE FIBER FOR AIR-BAGS AND TEXTILES MADE FROM SAME
Document Type and Number:
WIPO Patent Application WO/2011/078513
Kind Code:
A2
Abstract:
The present invention relates to polyethylene terephthalate chips which have intrinsic viscosity from 0.8 to 1.3 and which are made by spinning multi-filament polyethylene terephthalate. The present polyethylene terephthalate fabrics for making air-bags have improved energy absorption capability which is induced by adjusting the polyethylene terephthalate fiber strength / deformation curve. To adjust the strength / deformation curve, multi- filament polyethylene terephthalate is subject to the following stresses: an initial stress of 1.0 g / d at room temperature with extensions of less than 4 %, followed by a medium stress of 4.5 g / d with extensions of less than 12 %, and up to at least 7 g / d tensile stress and right up to the point the fibers snap, such that the polyethylene terephthalate has elongation of 15% or more, carboxy terminus (CEG) content of less than 35 mmol/kg and fiber thickness of less than 5 denier.
