Impregnation of Eicosane into Polyester Fiber Using Supercritical Carbon Dioxide

Article Preview

Abstract:

Supercritical impregnation of eicosane into polyester fiber was experimentally examined. Polyester fiber was bound on the cylindrical stainless steel net inside high pressure cylinder and was impregnated with supercritical eicosane solution. After an hour under supercritical condition, the system was expanded to atmospheric pressure and impregnated polyester fiber was obtained. Eicosane was successfully impregnated into the polyester fiber even at temperature below it’s glass transition(Tg), and the impregnated fiber showed high energy storage and release capacity around the melting point of eicosane.
