Dyeing method of superfine denier dry-spun acrylic fiber blended yarn fabric

The invention relates to a dyeing method of a superfine denier dry-spun acrylic fiber blended yarn fabric. The dyeing method comprises the step of dyeing the acrylic fiber blended yarn fabric by use of a dye and auxiliaries and comprises the following specific technological conditions: during open dyeing, the starting temperature of dyeing is in the range of 80-85 DEG C, and the concentration of the dye and the auxiliaries is reduced by 2%, or during closed dyeing, the starting temperature of dyeing is in the range of 85-90 DEG C, and the concentration of the dye and the auxiliaries is increased by 5%; a temperature rise rate in a temperature rise period ranges from 0.5 to 0.6 DEG C per minute, a temperature rise rate in a coloring period ranges from 0.2 to 0.3 DEG C per minute, and the temperature is controlled within the range of 97-98 DEG C after persistent temperature rise. The dyeing method of the superfine denier dry-spun acrylic fiber blended yarn fabric is used for completely solving the problems of u
