The invention discloses a method for tanning sheep shorn-pile. The method comprises the following steps: 11) degreasing, namely, adding water into a paddle-tumbler, subsequently adding degreasing agent, an enzymic preparation and sodium carbonate, adjusting the pH value of a first solution to be 7.3-7.8 so as to obtain a first solution, and stirring the first solution; 12) tanning the degreased fur by using an organic phosphine tanning agent; 13) oxidizing to remove the residual tanning agent; 14) re-tanning the fur after the oxidation is accomplished; 15) whitening, wet-grinding, cleaning, drying and settling the fur. According to the method for tanning sheep shorn-pile, the pickling step in the conventional tanning method is replaced by the degreasing step, and the purpose of opening the fiber of the fur is achieved by using the enzymic preparation used in the degreasing step instead of acid used in the pickling step, so that the purposes of reducing damage to human bodies in the pickling step and reducing environment pollution caused by a waste pickling liquid are achieved.
