The invention discloses a production method of an elastic puffed silk quilt, relating to the technical field of home textile preparation. The method comprises cocoon selecting, cocoon cooking, degumming, pupae removing, ring sleeving, thread insertion and wire drawing, and is characterized by also comprising the steps of (A) firstly soaking cocoons into purified water before cooking the cocoons, wherein the water temperature is 50-70 DEG C and the soaking time is 3-5 minutes, putting the cocoons and the purified water into a vacuum container after soaking is completed, adding an alkaline swelling agent of which the pH is 9-10 for cooking, wherein the cooking temperature is 90-100 DEG C and the cooking time is 5-10 minutes; and (B) soaking natural silk into the purified water after wire drawing is completed, wherein the water temperature is 70-80 DEG C and the soaking time is 3-5 minutes, soaking the natural silk into the purified water containing an acid swelling agent, wherein the water temperature is 20-30 DEG C and the soaking time is 2-4 minutes, and finally drying and arranging the natural silk. Compared with the prior art, the production method has the advantage that the problem that the elasticity of an existing silk quilt is easily reduced can be solved.
