Abstract
There is provided a polyester fiber which has few defects such as voids due to catalyst particles, and low variation in physical properties and minimal fluff generation. The polyester fiber of the invention comprises laminar nanoparticles composed of a divalent metal and a phosphorus compound and having side lengths of 5-100 nm and an interlayer spacing of 1-5 nm. There are also provided a tire cord, tire, belt-reinforcing fiber material and belt, comprising the polyester fiber.
