The invention belongs to the technical field of textile processing and relates to a knitted fabric dyeing method with a low living bath ratio. The knitted fabric is stained by carrying out steps such as knitted fabric pretreatment, dyeing, knitted fabric after-treatment and finishing in a dyeing system device with a low living bath ratio; a regulation and control process of an ultralow pretreatment liquid water level and dye liquor water level is adopted to achieve energy-saving dyeing; the defects of large water consumption, large dye additive dosage, long dyeing duration and the like of the traditional knitted fabric overflow dyeing method are overcome, and the problems of high pollution and high energy consumption in knitted fabric dyeing are solved; the integral process is simple, the design principle is scientific, the application and operation are safe and reliable, the energy saving and emission reduction effects are good, and the dyeing is environment-friendly.
