Abstract of the Invention The invention is a polyester and a method for producing a poyester ]filament which has a combination of flame resistance and low pilling properties. The method comprises forming a polyester polymer from a mixture of two polymers, the first compound being the reaction product of terephthalic acid or dimethyl terephthalate, ethylene glycol, and an oxysilicon compound and the second compound being the reaction product of terephthalic acid or dimethyl terephthalate, ethylene glycol 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.
