The invention discloses a wet rubbing and mechanical combined finishing method for a wool fabric. The wet rubbing and mechanical combined finishing method for the wool fabric is characterized by comprising the following steps: choosing dacron, an acrylic fiber and the like to blend with wool to form a blend fiber wool top; weaving the fabric from the wool top; feeding a gray fabric into a weaving machine, scotching, washing with water, and dehydrating; feeding the fabric into a finishing area, wetting the fabric through a prewetting sprayer again, finishing in a wet rubbing and finishing area after prewetting; conveying the fabric to a mechanical finishing area after finishing; and adopting double-sided vertical same-site opposite needling, and finally thermoforming. The wet rubbing and mechanical combined finishing method is used to conduct afterfinishing, the high-pressure water jet loosens the fabric, the tensile stress of the original fabric is eliminated, a fiber in the wool top tangles with a fiber in the adjacent yarn, the fabric finished by means of wet friction is subjected to repeated opposite needling under the condition containing water, so that the fibers are relatively sufficiently rubbed and tangle, the fibers are mutually locked and are firmer, a ground yarn is also almost fully covered, and the fabric is more compact.
