FLAME RESISTANT, LOW PILLING POLYESTER FIBER Abstract of the Invention The invention is a polyester and a method for producing a polyester fiber which has a combination of flame resistance and low pilling properties. The method comprises forming a polyester fiber made from a blend of two polyester polymers, one polyester polymer containing an oxysilicon compound and the second polyester polymer containing pentaerythritol and a phosphinic acid in the amount between 0.5 and 20 mole percent of the terephthalate acid and monomer. In particular, the invention also comprises the enhanced fiber formed by the process, as well as the fabrics having a pilling of about 3 to less than 5 as measured in accordance with ASTM D-3512-82.
