ABSTRACT

To acquire dyeing ability on aramid(Nomex) spun yarn in supercritical fluid dyeing, supercritical fluid dying(SFD) machine of 3L scale was designed. C.I. Disperse Red 60 and Red 360 were used in this work. It was possible to increase dyeing ability and to get level dyeing of fiber by attaching assistance devices(controlling device of supercritical fluid, nozzle, cover of carrier, etc.) to SFD machine. Physical properties(tensile strength, elongation, shrinkage) of Nomex spun yarn treated by SFD were not changed. K/S values of dyed Nomex spun yarn with Red 360 were higher than that with Red 60 and color fastness of dyed Nomex spun yarn by SFD was similar to that by conventional dyeing method.
