Document Type and Number:
WIPO Patent Application WO/2017/065305
Kind Code:
A1
Abstract:
Provided are: a rubber-reinforcing fiber of which durability can be further improved over that of conventional fiber when used as a reinforcing material by enhancing adhesiveness between a rubber and a fiber; a rubber-fiber complex; and a pneumatic tire using the complex. The rubber-reinforcing fiber is made from a core-in-sheath conjugate fiber in which the core part comprises a high-melting-point resin (A) having a melting point of at least 150°C, and the sheath part comprises a resin material (B) having a lower melting point than the high-melting-point resin (A). The resin material (B) contains an olefin polymer (X) and a vulcanization accelerator (F).
