China's domestic polyester staple fiber (PFA) prices gained 400 to 500 yuan per ton from prices ruling 30 days back.
Price range this week has been between 10,800 to 11,100 yuan per ton, which relates to 60.81 to 62.49 US cents per pound, revealed a survey on average market price, this week.
This gain has possibly been brought about by improved demand for staple fiber and continued preference of cotton over polyester.
Present price level indicates producers are operating on a narrow profit margin basis.
