The invention relates to a dyeing method of memory fabric. Processes of refining and dyeing are carried out in one bath, and the method comprises the following steps: (1) feeding the fabric into a dyeing machine; (2) adding softeners and stabilizers into a dye bath after feeding the fabric, rotating for 5-10 minutes, adding dispersants and leveling agents, and then rotating for 5-10 minutes; (3) beating in alkali disperse dye slowly, heating to 70-90 DEG C at 0.6-1.0 DEG C per minute, insulating for 8-12 minutes, heating to 110-115 DEG C at 0.6-1.0 DEG C per minute after feeding the dye, insulating heat for 8-12 minutes, then heating to 120-125 DEG C at 1-1.1 DEG C per minute, insulating heat for 30-45 minutes, cooling to under 60 DEG C at 1.2-1.3 DEG C per minute finally and discharging bath solutions; and (4) washing and outputting the fabric. The method has simple process, the energy consumption can reduce by 50 percent compared with the prior art, and the dyeing period is dramatically shortened.
