Abstract
Method of manufacturing polyester fibers with good adhesiveness to rubber, characterized in that in the process of making polyester fiber into yarn, a yarn-making oil (spin finish) containing an epoxy compound and an alkylene oxide adduct of an amine compound containing an alkoxysilane group is added to the polyester fiber, and it is then heat-treated.
