The invention discloses an identical reaction kettle reel-to-reel plasma ultrasonic supercritical non-aqueous dyeing system, comprising a general control console, a carbon dioxide storage bottle, a high-pressure pump, a dye tank, a heat exchange device, a reaction kettle, a dye recycling tank, a filter, a condenser, a liquid carbon dioxide storage tank, a flow meter, a valve and a pipeline, and characterized in that the reaction kettle is provided with an upper electrode and a lower electrode of a plasma generator, an exhaust valve and a vacuum pump, is internally provided with one or a plurality of groups of reel-to-reel or axis-to-axis wind and relative motors, is also internally provided with one or a plurality of groups of agitating devices and relative motors, and is embedded with an ultrasonic transducer connected with an ultrasonic wave generation device. The plasma realizes the modification for the surface of material, the ultrasonic wave disperses the dyes uniformly, the supercritical carbon dioxide realizes non-aqueous dyeing, and the reel-to-reel way realizes non-intermittent continuous industry production. The invention can meet the most rigorous environment-friendly demand and product safety demand.
