Abstract
PURPOSE: The titled fibers, consisting of ethylene terephthalate as main constituent units, having the secondary yield point of a specific value or above and a negative gradient in a region of higher elongation than the yield point, improved low shrinkage and fatigue resistance, and suitable for reinforcing rubber structures.
CONSTITUTION: Fibers, consisting of a polyester containing ethylene terephthalate as main constituent units, showing the secondary yield point ≥4.5g/deniers in a load-elongation curve, and having a part with a negative gradient, preferably a neagtive gradient ≥-0.84g/deniers/%, in a region of higher elongation than the yield point. Preferably, the strength at break is ≥5.0g/denier, and the dry heat shrinkage at 175°C is ≤9%. The resultant fibers are made into cords, which are heat-treated at a constant length or stretching to 20% at 200W260°C for a sufficient time, usually 30W240sec, to exhibit the maximal properties thereof.
