摘要：

The effect of dyeing in supercritical fluids on characteristics of the polymeric structure is investigated using poly(ethylene terephthalate) fibers. The supercritical fluid (CO2) causes a decrease in the glass transition temperature and the formation of a network of stabilizing crystallites, which - without the use of a fluid - can only be obtained at significantly higher temperatures. The implications of fiber structure for successful dyeing or impregnation of fibrous material in supercritical systems are discussed.
