全球丙烯腈短纤的产量到 1 998年底继续保持在每年 2 60万 t的水平 ,尽管三个最发达的地区产量有所下降 (表 1 )。例如 ,美国前年产量下降了 2 5% ,由原先的 2 0 .39万 t下滑到 1 5.7万 t,这是 1 0年内的最低产量。西欧丙烯腈纤维产量在三个地区是最大的 ,也从 1 997年的 70 .1 Global acrylonitrile staple fiber production continued at the end of 1 998 at a level of 2 600,000 t per year, although output declined in the three most developed regions (Table 1). For example, the U.S. production in the previous year fell by 25%, from the original 203.9 thousand t to 157,000 t, which is the lowest output in 10 years. Acrylonitrile fiber production in Western Europe is the largest in three regions, also from 70. 1 in 1997
