The invention provides a method for waving an electromagnetic wave absorbing fabric. The method is characterized in that yarns with material coatings capable of absorbing and reflecting electromagnetic waves are taken as warp tarns, weft yarns and binding yarns, and a three-dimensional structure electromagnetic wave absorbing fabric with hoes of gradual changes is arranged in the thickness direction of weaving. The holes of gradual changes can cause multiple reflection and absorption effects, thereby achieving electromagnetic wave absorption. A carbon nanotube material coating in the fabric can absorb and reflect electromagnetic waves, and the holes of gradual changes can cause the multiple reflection and absorption effects, thereby achieving absorption of the electromagnetic waves. The method has the advantages of being simple, suitable for industrial production, and wide in application prospect in the field of military and civil protection.
