2004年全球聚酯纤维再次以增长率 9. 7%,产量 24. 5×106 t居于全球化学纤维生产之首。所有聚酯纤维的品种如短纤维、纺织纤维、工业长丝对这一成绩均有贡献。其中短纤维产量 10. 3×106 t,主要集中在中国大陆和美国。两国事实上都提高了产量。中国大陆提高了 21%,达到 4. 4×1 Polyester fiber in 2004 once again to the growth rate of 9.7%, yield 24.5 × 106 t living in the global chemical fiber production of the first. All polyester fiber varieties such as staple fiber, textile fiber, industrial filament contribute to this result. Among them, short fiber production was 10.3 × 10 6 t, mainly in mainland China and the United States. Both countries actually increased their output. Mainland China increased by 21% to 4. 4 × 1
