The recently announced sale of its parent company will not affect a Screven County textile company’s compliance with permit and testing mandates. The sale also will not affect a consent agreement the company has with the Georgia Environmental Protection Division to help protect the Ogeechee River from pollution. Milliken & Company, which is based in Spartanburg, S.C., and owns industries in several countries, announced Friday that it acquired Westex Inc., the Chicago-based company that owned King America Finishing, a textiles plant in Dover specializing in flame-retardant material.
