The invention belongs to the technical field of dyeing processing, and particularly relates to an overflow dyeing method of light alkali mercerized knitted fabric. The overflow dyeing method of the knitted fabric after light alkali mercerizing is used for dyeing the knitted fabric woven by 50 or more cotton yarns, and comprises the following procedures: singeing, mercerizing, oxygen bleaching, dyeing, soaping, color fixing and polishing, and the conditions of the polishing procedure are as follows: the pH value is 5-6, the polishing temperature is 50-60 DEG C, the polishing time is 50-80 minutes, and the dosage of polishing enzyme is 0.2-0.5 wt.%. Aiming at the defects of low density, unstable shrinkage density and size and poor stiffness of the existing knitted fabric in the market, the invention provides the overflow dyeing method for the knitted fabric after light alkali mercerizing, the dyeing is uniform, no dyeing defect and stain exist, and the fabric surface is not easy to scratch. 本发明属于染色加工技术领域，具体涉及淡碱
