A polyester resin, a method for its preparation, the polyester prepared by the method, a method for manufacturing therefrom at increased productivity a dimensionally stable polyester yarn having a low fray count, and the yarn thereby produced. The polyester resin is prepared from high purity terephthalic acid having a particle size distribution described by a Weibull function with narrow ranges of characteristic size and shape factor. The polyester resin has a low filter-blinding index. The polyester yarn is useful for tires, industrial products and other applications. |
