    摘要： A polyester composition contains polyester, a phosphoric acid and an alkali metal phosphate, a phosphorous element content P (mol/t) is 1.8 mol/t or more and 5.0 mol/t or less relative to the whole of the polyester composition. The polyester composition contains at least one metal element of Mn and Ca, any divalent metal element content other than Mn and Ca is 5 ppm or less, and when an alkali metal element content relative to the polyester composition is denoted by M1 (mol/t), and a total amount of Mn element content and Ca element content relative to the polyester composition is denoted by M2 (mol/t), a metal element content M (mol/t) in the polyester composition which is calculated by expression (i) below and the phosphorous element content P (mol/t) satisfy expression (ii): (i) M=M1/2+M2 and (ii) 1.1≦M/P≦3.0.

    摘要翻译： 聚酯组合物含有聚酯，磷酸和碱金属磷酸盐，相对于整个聚酯组合物，磷元素含量P（mol / t）为1.8mol / t以上且5.0mol / t以下。 聚酯组合物含有至少一种Mn和Ca的金属元素，Mn和Ca以外的二价金属元素含量为5ppm以下，当相对于聚酯组合物的碱金属元素含量为M1（mol / t ），并且相对于聚酯组合物的Mn元素含量和Ca元素含量的总量以M2（mol / t）表示，聚酯组合物中的金属元素含量M（mol / t）由式（i ）和磷元素含量P（mol / t）满足表达式（ii）：（i）M = M1 / 2 + M2和（ii）1.1 @ M / P 3.0。
