The invention discloses a method that is used for finishing wool fabrics by catalyzing a foreign protein through a transglutaminase and belongs to the filed of biotechnological application. The method implements proper chemical or protease preprocessing on wools, grafts and coats a gelatinum of the foreign protein or a caseinum on the surface of wool fibers under the catalysis of the transglutaminase, endues the wool fabrics with certain felt-proof property, and improves the physical and mechanical performance of the wool fabrics to a certain degree. Compared with the traditional felt-proof finishing methods of the wools, the method that is used for finishing the wool fabrics by catalyzing the foreign protein through the transglutaminase replaces traditional chemical finishing agents with bio-enzyme and biomacromolecule, has less fiber strength loss and is easier to control by comparing with pure protease processing, leads the biological modification of the wools to be possible, greatly lowers environmental pollution, reduces COD in discharged water and improves ecological environment; simultaneously the method has gentle action condition, avoids high-temperature baking, saves energy and improves the quality of fabric products.
