  • Making high filament count fine filament polyester yarns
    Patent number: 5827464
    Abstract: A direct melt spinning process for providing high filament count fine filament polyester yarns having excellent mechanical quality and along-end uniformity and unitary interlace by spinning all the filaments of such high filament count yarn from a single spinneret. Such yarns may be used as direct-use yarns and as draw-feed yarns for preparing drawn flat yarns and draw-textured yarns.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: October 27, 1998
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: David George Bennie, Robert James Collins, Hans Rudolf Edward Frankfort, Stephen Buckner Johnson, Benjamin Hughes Knox, Joe Forrest London, Jr., Elmer Edwin Most, Jr., Girish Anant Pai

  • Polyester mixed yarns with fine filaments
    Patent number: 5691057
    Abstract: Polyester mixed fine filament yarns having excellent mechanical quality and uniformity, and preferably with a balance of good dyeability and shrinkage, are prepared by a simplified direct spin-orientation process by selection of polymer and spinning conditions.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: November 25, 1997
    Assignee: E. I. Du Pont de Nemours and Company

  • Process for depolymerizing waste ethylene terephthalate polyester
    Patent number: 4078143
    Abstract: Recovery of ethylene terephthalate polymer from waste material is accomplished by glycolysis of the polyester to form bis-(2-hydroxyethyl)terephthalate for repolymerization. Formation of objectionable diethylene glycol is inhibited when glycolysis is accomplished by heating the polyester in a reaction mixture with bis-(2-hydroxyethyl)terephthalate, ethylene glycol and sodium acetate trihydrate, and water is introduced continuously into the reaction mixture during depolymerization of the polyester.
