Title: Walter G. De Witt, III: Innovator in Nonwoven Fabrics and Coating Compositions
Introduction
Walter G. De Witt, III is a notable inventor based in Southampton, PA (US). He has made significant contributions to the field of materials science, particularly in the development of nonwoven fabrics and coating compositions. With a total of 2 patents, his work has had a meaningful impact on various applications.
Latest Patents
One of his latest patents is for "Bonded nonwoven fabrics suitable for diaper coverstock." This invention focuses on a nonwoven fabric specifically designed for use as a diaper coverstock. The fabric is composed primarily of fibers and a binder, with at least 50% of the fibers being hydrophobic. The binder is a water-insoluble, hydrophobic emulsion copolymer made from a mixture of ethylenically unsaturated monomers. This innovative fabric possesses sufficient wet tensile strength for effective use in diaper coverstock.
Another significant patent by De Witt is for "High impact resistant coated articles." This invention involves coating compositions that include an acrylic solution polymer with a molecular weight ranging from 30,000 to 250,000 and a glass transition temperature (Tg) above 65°F. The composition also includes a compatible acrylic polymer with a Tg less than -20°F, which is soluble in the same solvent. This technology enhances the impact resistance of coated substrates, particularly impact-modified acrylic sheets.
