Title: James Samuel Dalton: Innovator in Polyester and Paper Machine Fabric Technologies
Introduction
James Samuel Dalton is a notable inventor based in Kingsport, TN (US). He has made significant contributions to the field of materials science, particularly in the development of innovative polyester blends and paper machine fabrics. With a total of 2 patents, Dalton's work has had a meaningful impact on various industries.
Latest Patents
Dalton's latest patents include a compositional blend that features a polyester, an acetaldehyde reduction compound, and less than 50 ppm of an optical brightener. This blend is particularly useful for food and beverage molded containers, where improved clarity and flavor retention are essential without producing haze. The acetaldehyde reduction compound can be a low molecular weight partially aromatic polyamide, a low molecular weight aliphatic polyamide, or polyesteramide. The optical brightener is preferably a bis(benzoxazolyl) stilbene, ensuring that articles produced from this blend, especially beverage containers, maintain a yellowness, b*, of less than about 2.5.
Another significant patent involves an article of paper machine fabric used in papermaking machines. This fabric comprises a fibrous structure made of monofilament yarns, which consist of a polyester made from about 85 to 100 mole % of 2,6-naphthalenedicarboxylic acid and about 85 to 100 mole % of ethylene glycol or 1,4-cyclohexanedimethanol. This invention provides excellent resistance to hydrolytic and dry heat degradation, good dimensional thermal stability, and resistance to deformation.
