In 2011, global production of chemical fibers increased by 5.9 million tons or 12% to 53.8 millions tons. The worldwide production of textile fibers increased by 8.5 millions tons or 12% to 80.1 millions tons. In total, natural fiber production expanded to 26.3 million tons (+11%).
Within chemical fibers, 50.2 million tons (+12%) were synthetic fibers (excluding acetate cigarette filter tow.) This led the way for global synthetic fiber production to increase by 5.4 million tons and cellulosic fibers by 450,000 tons. The production of lyocell staple fibers, however, with a worldwide capacity of 145,000 tons/year in 2011, is not covered by the cellulosic fiber statistic as over 95% of production is covered by the Lenzing Group (trademark Tencel).
In 2011, global polyester fiber production in creased by 14% or 4,5 million tons to 37,3 million tons. Of this, 23.6 million tons(+16%) was filament yarns and 13.7 million tons (+9%) staple fibers. This means that 74% of total synthetic fiber production (including PP fibers) were attributed to polyester fibers.
