Abstract

PURPOSE: Titled fibers that is made from a polyethylene terephthalate composition resulting from the reaction of a specific ester monomer therewith, thus being suitably used as a rubber-reinforcing material such as tire cords, because they can sustain enough strength even under high speed and high load conditions where high temperatures are generated.
CONSTITUTION: (A) A polyester containing ethylene terephthalate as the major recurring unit is combined with (B) 0.5W7wt%, based on the component A, of monomer, prepolymer or polymer of ester from a condensed polycyclic dicarboxylic acid or dicarboxylic acid having 2 or more benzene rings such as a compound of formula I or II and they are made to react to give a composition. Then, the composition is, e.g., melt extruded through spinnerets, drawn to produce the objective fibers.
