Title: Innovations of Richard J Coffin
Introduction
Richard J Coffin is a notable inventor based in Conyers, Georgia, with a focus on polymer filament technology. He holds two patents that showcase his expertise in creating advanced materials with unique properties. His work has contributed significantly to the field of polymer science.
Latest Patents
Coffin's latest patents include a "Melt spin system for producing skin-core high thermal bond strength" and a "Process of making skin-core high thermal bond strength fiber." Both patents describe a process and apparatus for spinning polymer filaments. The process involves feeding a polymer composition to a spinnerette at a flow rate sufficient to achieve a spinning speed of about 10 to 200 meters per minute. The polymer composition is heated at a location adjacent to the spinnerette to obtain a skin-core filament structure upon quenching in an oxidative atmosphere. The heated polymer composition is extruded through the spinnerette to form molten filaments, which are then quenched to effect oxidative chain scission degradation, resulting in filaments with a skin-core structure.
