Effective December 1, Charlotte-based DAK Americas LLC will increase the price of its polyester staple fiber products by 3 cents per pound. In addition, Wellman Inc., Fort Mill, S.C., will increase the price of its Fortrel® polyester staple fiber products on December 1 by 3 cents per pound.

Both companies attribute the price increases to continued high costs of such raw materials as ethylene glycol.
