Patents by Inventor Keith James Carnes

Keith James Carnes has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polyethylene glycol modified polyester fibers and method for making the same
    Patent number: 6623853
    Abstract: Disclosed is a method of copolymerizing polyethylene glycol (PEG) and branching agent into polyethylene terephthalate (PET) to achieve a polyethylene glycol-modified polyester composition that can be spun into filaments. Fabrics made from fibers formed from the copolyester composition possess wicking, dyeability, and tactility properties that are superior to those of fabrics formed from conventional polyethylene terephthalate fibers of the same yarn and fabric construction. Also disclosed are polyethylene glycol modified copolyester compositions, fibers, yarns, and fabrics.
    Type: Grant
    Filed: March 8, 2001
    Date of Patent: September 23, 2003
    Assignee: Wellman, Inc.
    Inventors: James Burch Branum, Keith James Carnes, Billy Mack Humelsine, Carl Steven Nichols

  • Nonwoven fabrics formed from polyethylene glycol modified polyester fibers and method for making the same
    Patent number: 6582817
    Abstract: Disclosed is a nonwoven fabric that is formed of polyethylene glycol modified copolyester staple fibers. The copolyester staple fibers include polyethylene terephthalate in an amount sufficient for the copolyester staple fibers to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester staple fibers to possess wicking characteristics that are superior to those of conventional, unmodified polyethylene terephthalate fibers, and chain branching agent in an amount less than about 0.0014 mole-equivalent branches per mole of standardized polymer. Also disclosed are methods for making such nonwoven fabrics.

  • Polyethylene glycol modified polyester fibers
    Patent number: 6509091
    Abstract: Disclosed is a polyethylene glycol modified copolyester fiber that has exceptional moisture management characteristics and that can be formed into exceptionally comfortable fabrics. The copolyester fiber includes polyethylene terephthalate in an amount sufficient for the copolyester fiber to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester fiber to possess wicking properties that are superior to those of conventional, unmodified polyethylene terephthalate fibers, and chain branching agent in an amount less than about 0.0014 mole-equivalent branches per mole of standardized polymer.
