Abstract:
This invention is polyester fibers with an initial tensile resistivity of 15 to 38 cN/dtex, a elastic recovery rate of 70% or more after 20% elongation, and a self-shrinkage percentage of 0.3% to 1.4% after dry heat treatment at 160° C. The polyester fibers of this invention can be used to obtain a woven or knitted fabric resistant against repeated loads, excellent in surface softness and uniformity, and free from projections/recesses and curling. Since the woven or knitted fabric obtained from the polyester fibers of this invention are highly resistant against repeated loads, it can be suitably used as a car seat loaded with human bodies.
