Antistatic polyester fibers

摘要

A hollow polyester fiber with excellent antistatic properties composed of a single polymeric component and having a hollow extending along the longitudinal axis thereof and in which the hollow ratio is at most 15%, which fiber contains (a) a polyoxyalkylene glycol substantially non-reactive with said polyester and (b) an ionic antistatic agent, dispersed through the fiber in an amount of at most 3% by weight based on the weight of the fiber, and wherein the polyoxyalkylene glycol (a) is predominantly dispersed in a core portion of the fiber in a high density. The fiber also has excellent tensile strength, resistance to fibrillation and dyeing properties.
