ABSTRACT:
A method is disclosed of producing a blended fabric of polyester and cotton with superior low pilling characteristics. The method comprises polymerizing a melt consisting essentially of terephthalic acid, ethlyene glycol and at least about 1300 parts per million of pentaerythritol to an intrinsic viscosity of at least about 0.55 dl/g. The resulting polymer can be spun into filament, textured, cut into staple, spun into yarn, and formed into fabric. The method and resulting polyester also have advantages in the production of polyester bottle resin and the resulting bottles.
