Abstract
The present invention is a composition comprising a surfactant blend of nonionic and anionic surfactants useful for the removal of oligomer deposits from polyester fibers and polyester processing equipment. The composition of the present invention includes a surfactant blend of an ethoxylated sorbitan ester and at least one additional nonionic or anionic surfactant. The combination of the ethoxylated sorbitan ester and additional surfactants used in the invention surprisingly has a synergistic effect on the removal of oligomer deposits from polyester fibers and polyester processing equipment.
