Title:
POLYESTER FIBER AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2012/002749
Kind Code:
A2
Abstract:
The present invention relates to industrial high-strength polyester fiber to be used in a seatbelt, webbing, and the like. More particularly, the present invention relates to polyester fiber and to a method for preparing same, wherein the polyester fiber has an elongation of 0.5% or higher at a stress of 1.0 g/d measured at room temperature, an elongation of 4.3% or higher at a stress of 4.0 g/d, and an elongation of 7.5% or higher at a stress of 7.0 g/d. The polyester fiber of the present invention is optimized to have high strength, a low modulus and high elongation, thus ensuring superior mechanical physical properties. Therefore, a seatbelt having superior shock-absorbing properties and significantly improved wear resistance and heat-aged breaking strength retention can be prepared from the polyester fiber of the present invention.
