Title:
RUBBER-REINFORCING FIBER, PROCESS FOR PRODUCING THE SAME, AND RUBBER PRODUCT AND PNEUMATIC TIRE EACH MADE WITH THE SAME
Document Type and Number:
WIPO Patent Application WO/2001/083874
Kind Code:
A1
Abstract:
A rubber-reinforcing fiber which has a coating layer having a thickness of 10 Å to 40 µm. The coating layer is formed by a dry deposition method and comprises at least one metal and/or metal compound selected from the group consisting of cobalt, zinc, copper, titanium, silver, nickel, and compounds of these metals. Due to the coating layer, the rubber-reinforcing fiber is tenaciously bonded to a rubber ingredient to thereby improve the fatigue resistance and durability of a rubber product, especially a pneumatic tire.
