The invention relates to a wool fabric capable of being washed in a machine. The wool fabric comprises wool fibers and vinylon fibers, wherein the fineness of the wool fibers ranges from 85 s to 150 s, and the length of the wool fibers ranges from 95 mm to 115 mm; the specification of the vinylon fibers is 3.5-4.5 dtex*50-75 mm. The wool fabric is characterized in that the wool fibers and the vinylon fibers contain tensile auxiliaries, and the weight ratio of the wool fibers to the vinylon fibers is (60-68):(70-75). Compared with the prior art, the wool fabric has the advantages that the tensile auxiliaries are added into the wool fibers and the vinylon fibers, and therefore the wool fabric slightly deforms after being washed in the machine and is convenient to wash.
