<P>PROBLEM TO BE SOLVED: To provide a polyester fiber-rubber bonded product which can ensure the same adhesive force to the rubber as that on conventional two dipping treatments only by one dipping treatment at a heating temperature not deteriorating the physical properties of the polyester fibers. <P>SOLUTION: The polyester fibers are preliminarily treated with a corona discharge treatment or the like to form a polar multifunctional groups. The ratio of resin components and the ratio of the resin component to the rubber in a dipping adhesive liquid is suitably adjusted. Thereby, a sufficient adhesive force can be ensured only by one dipping treatment, even when a heating treatment temperature after the dipping treatment is 200 to 225°C neglecting the effect to the physical properties of the polyester fibers. <P>COPYRIGHT: (C)2004,JPO |
