Behind the Rising Price of Polyester
For years, the primary indicator of polyester fiber or filament cost was the fluctuation in petroleum prices. If the price of a barrel of oil increased, so did the price per pound of the base synthetic ingredient: polyester staple fiber (PSF).
“This last eight months has been different,” says Alasdair Carmichael, president of the Americas division of the U.K.-based PCI Fibres. “Oil has been increasing, but the rate of increase at the fiber level has been greater than the increase at the oil level.” A new factor has come into play in the past year, and it’s surprised industry watchers. The price increases this year are demand-driven, Carmichael says, and the additional demand is due, in large part, to a shortage of cotton.
