Drawing Nylon 6,6 Fibers in High Pressure CO2

摘要

Research studies have been performed on various fibers using supercritical carbon dioxide treatments. In these studies, Nylon6,6, PBO (Zylon) and other polyester fibers are treated under various conditions and post -treated fiber properties are measured and reported. In this research, supercritical CO2 is used as a plasticizing medium, a transport medium, and as a pressurizing medium to enhance the mechanical performance of selected high performance fibers. In a variety of cases, moderate enhancements in mechanical behavior are observed.
