Patent number: 8524343Abstract: The present invention relates to titanium-catalyzed polyethylene terephthalate resins that are capable of being formed into articles (e.g., carbonated soft drink and water bottle preforms) at reduced injection-molding cycle times. In particular, the titanium-catalyzed polyethylene terephthalate resins of the present invention can be formed into carbonated soft drink bottle preforms at reduced injection-molding cycle times to yield high-clarity, carbonated soft drink bottles that possess satisfactory resistance to stress cracking and thermal creep.Type: GrantFiled: August 16, 2011Date of Patent: September 3, 2013Assignee: DAK Americas Mississippi Inc.Inventors: David Eugene Thompson, Carl Steven Nichols, Tony Clifford Moore, Sharon Sue Griffith, Billy Mack Humelsine, Robert Joseph Schiavone

Patent number: 6623853Abstract: 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: GrantFiled: March 8, 2001Date of Patent: September 23, 2003Assignee: Wellman, Inc.Inventors: James Burch Branum, Keith James Carnes, Billy Mack Humelsine, Carl Steven Nichols

Patent number: 6485829Abstract: A polyester composition is disclosed that is particularly suitable for filament. The composition is formed of polyethylene terephthalate; polyethylene glycol in an amount sufficient to increase the wetting and wicking properties of a filament made from the composition to a level substantially similar to the wetting and wicking properties of cotton and other cellulosic fibers (natural or synthetic) but less than the amount that would reduce the favorable elastic memory properties of the polyester composition; and a chain branching agent selected from the group consisting of trifunctional alcohols and acids and tetrafunctional alcohols and acids that will copolymerize with polyethylene terephthalate, the chain branching agent being present in an amount sufficient to raise the melt viscosity of the polyester composition to a level that permits filament manufacture under conditions that are substantially the same as those under which filament can be formed from unmodified polyethylene terephthalate.Type: GrantFiled: May 9, 2001Date of Patent: November 26, 2002Assignee: Wellman, Inc.Inventors: Carl S.

Patent number: 6221488Abstract: A method is disclosed of producing a blended fabric of polyester and cotton with superior low pilling characteristics. The method comprises polymerizing a melt consisting essentially of terephthalic acid, ethylene glycol and at least about 1300 parts per million of pentaerythritol to an intrinsic viscosity of at least about 0.55 dl/g. The resulting polymer can be spun into filament, textured, cut into staple, spun into yarn, and formed into fabric. The method and resulting polyester also have advantages in the production of polyester bottle resin and the resulting bottles.Type: GrantFiled: July 27, 2000Date of Patent: April 24, 2001Assignee: Wellman, Inc.Inventors: Billy Mack Humelsine, Carl S.
