The invention relates to a dyeing and finishing process of rayon fabric containing acrylic yarn. The process comprises steps as follows: primary woven rayon fabric is subjected to dyeing pretreatmentand antistatic and crease-resistant finishing; the steamed and set primary woven rayon fabric is subjected to dye discharge print, that is, the primary woven rayon fabric is soaked in a staining solution, wherein the staining solution comprises a 1 ml/L colorant and a 1 ml/L chelating agent; the temperature is increased to 40-50 DEG C and steamed by a steamer with the steam pressure of 2 kg, the temperature is curvedly increased to 50-60 DEG C, the fabric is kept at the constant temperature for 10 min, table salt and sodium carbonate which have the equal mass of 3-5 g/L are added, the temperature is curvedly increased to 60-70 DEG C, the fabric is kept at the constant temperature for 10 min, a color fixing agent is added, and aftertreatment is performed. The fabric obtained with the methodhas high third-dimension discharge print dyed flowers, is firmly dyed, has the moisture-permeable and uvioresistant effects reaching the satisfied degree and has good dyeing effects.
