Title: Edgar N Rudisill: Innovator in Polymer Fiber Technology
Introduction
Edgar N Rudisill is a prolific inventor based in Nashville, TN, holding an impressive portfolio of 21 patents. His innovative contributions primarily revolve around advancements in polymer fiber technology, demonstrating a significant impact in the textile industry.
Latest Patents
One of his latest patents is for a "Low Shrinkage, Dyeable MPD-I Yarn." This invention involves a heat-treated poly(metaphenylene isophthalamide) polymer fiber characterized by a crystalline structure that showcases a carbonyl stretch peak at a wavelength of 1,650 cm−1 in Raman spectra. Notably, before the dyeing process, the fiber exhibits a linear shrinkage of 0.4 percent or less when exposed to 285 degrees Celsius for 30 minutes. After dyeing with an aqueous red dye solution at 120 degrees Celsius for one hour, the 'L' value coloration of the fiber is at least 40 units lower than its original value.
Another significant patent addresses the "Method and Apparatus for Heating Nonwoven Webs." This innovative process enables the drying and heat treatment of nonwoven webs, allowing them to be partially dried under tension in one zone, followed by further heat treatment in a second zone under low or no tension. Such a method significantly reduces stretch-type defects in the nonwoven materials.
Career Highlights
Rudisill has contributed his expertise to renowned companies, including E.I. DuPont de Nemours and Company, and Invista North America S.à r.l. His work in these organizations has played a crucial role in elevating the standards of polymer fibers and nonwoven textiles.
