Title: The Innovations of Donald Albert Shiffler
Introduction
Donald Albert Shiffler is a notable inventor based in Kinston, NC (US). He has made significant contributions to the field of nonwoven fabrics, holding a total of 6 patents. His work focuses on enhancing fabric characteristics through innovative methods.
Latest Patents
One of his latest patents is a method for foam bonding of spunlace fabric to produce enhanced fabric characteristics. This method involves hydroentangling a nonwoven web to increase strength and abrasion resistance while maintaining desirable hand and drape characteristics. The process includes carding and cross-lapping synthetic and/or natural fibers to form a substrate. The substrate is then hydroentangled under relatively low pressure to create a spunlace web. A foam adhesive latex binding material is applied to the spunlace web, followed by a force that causes the binding material to penetrate the web fully. The resulting hydroentangled nonwoven web provides an enhanced balance of tensile properties, abrasion resistance, and fabric aesthetics.
Career Highlights
Throughout his career, Donald has worked with prominent organizations such as E.I. DuPont De Nemours and Company and North Carolina State University. His experience in these institutions has allowed him to develop and refine his innovative techniques in fabric technology.
