PURPOSE:To obtain polyester fibers having improved adhesive property to rubber, by applying a spinning oiling agent containing an epoxy compound and a specific silane compound to the polyester fibers in the fiber making step, and heat-treating the resultant fibers. CONSTITUTION:In a step for preparing polyester fibers, a spinning oiling agent containing (A) an epoxy compound, e.g. gamma-glycidoxypropyltrimethoxysilane, (B) an alkylene oxide adduct of an amine compound having an alkoxysilane group, and if necessary (C) a polymerization catalyst for the alkoxysilane group is applied to the polyester fibers, which are then heat-treated to give the aimed fibers. |
