全球经济的复苏将会推进纺织品对合成纤维的需求,预测未来7年内合成纤维的原料,PTA、EG、丙烯腈(ACN)、己内酰胺(CPL)、对二甲苯的生产能力可能会发生快速扩张。一、PTAPTA的生产能力可能由2000年的2372．2万吨上升到2007年的2761．6万吨,7年内生产能力将扩张19%。估计PTA的产量将从2000年的2047．3万吨上升到2007年 The recovery of the global economy will push forward the demand for synthetic fibers in textiles. It is predicted that the production capacity of synthetic fibers such as PTA, EG, ACN, CPL and paraxylene will expand rapidly in the next seven years. First, the production capacity of PTAPTA may increase from 23,722,000 tons in 2000 to 27,616,000 tons in 2007, and its production capacity will expand by 19% in seven years. PTA production is estimated to rise from 20.473 million tons in 2000 to 2007
