Zusammenfassung:The invention relates to a cotton knitted fabric active dye refining and dyeing one-bath method. According to the method, a tea saponin compounding agent is adopted as a pretreatment surfactant in the refining and dyeing one-bath method; with the method, contradiction between refining and dyeing is effectively solved, a good color fixation rate is obtained, refining and dyeing one-bath is achieved, and light, medium and dark fabrics can be dyed; the method has characteristics of process shortening, water and energy source consumption reduction, reduction of BOD and COD emission in wastewater, and the like, such that the method is an effective approach for achieving high efficiency, energy saving, and environmental protection cotton fabric production; the method further has characteristics of simple operation and easy production; the process comprises the following two sets of processes: (1) adding tea saponin, a penetrant, a stabilizer, a refining agent, an active dye, a salt and a color fixation substitute a
