ABSTRACT:
A polyester fiber highly heat-resistant in a rubber matrix and useful as a reinforcing material for rubber articles, has a tensile strength of 8 g/d or more and is composed of a core portion made from a polyester resin and a skin portion made from a polyester resin and covering the core portion, the skin portion being in an amount of 5% to 20% based on the entire amount of the fiber and having a lower orientation and/or lower crystallinity than the core portion, which polyester fiber has been produced by treating a surface portion of a homogeneous polyester fiber consisting essentially of a polyester resin with a solvent capable of swelling the polyester resin or by coating a precursory polyester fiber for the core portion with a polyester resin for the skin portion.
