A dyeing process of the wool yarn adopts a one-bath two-step method, and includes a primary dyeing procedure and a secondary dyeing procedure; each of the primary dyeing procedure and the secondary dyeing procedure contains three constant temperature stages, with constant temperatures of 40 DEG C, 70 DEG C and 98 DEG C; the wool yarn dyed by adopting the dyeing method is subjected to spooling, weaving, gum application, shearing, inspection and packing to prepare a double-color wool yarn carpet. The one-bath two-step method is adopted to dye the yarn for twice, and after constant temperature dyeing is performed for three times, the wool yarn has a one-thread double-color effect; the carpet made by using the double-color wool yarn is rich in color and quantity and good in softness and has the effect of imitating a handmade carpet, and the quality of the wool carpet is improved.
