The invention discloses low-radiation fabric containing double silver film layers. A composite film layer is deposited on the surface of the fabric with a magnetron sputtering vacuum deposition methodand comprises a first dielectric layer, a first oxide layer, a first silver layer, a first battier layer, a second dielectric layer, a second oxide layer, a second silver layer, a second barrier layer and a third dielectric layer by sequentially stacking from the surface of the fabric to outside. By means of the composite film layer with the structure, the two silver layers jointly have an effectof reflecting infrared thermal radiation, better low-radiation effect is realized, sufficient visible light transmittance can be guaranteed by means of small thickness of each layer, and original color and texture of the fabric are reserved. All the fabric can be endowed with an infrared thermal radiation shielding function rapidly on a large scale, and better warm keeping and thermal insulatingeffects are realized. Further, magnetron sputtering vacuum deposition is free of any chemical addition, water pollution or air pollution and is an environment-friendly production mode.
