The invention relates to an environment-friendly fabric and a drying method thereof. The environment-friendly fabric is characterized by comprising a first fabric layer, a second fabric layer and a third fabric layer, wherein the second fabric layer is positioned between the first fabric layer and the third fabric layer; bulges of which the cross sections are triangular are formed in two sides of the second fabric layer; a first groove of which the cross section is triangular is formed in the side, facing to the second fabric layer, of the first fabric layer; a second groove of which the cross section is triangular is formed in the side, facing to the second fabric layer, of the third fabric layer; the bulges of the second fabric layer are matched with the first groove in the first fabric layer and the second groove in the third fabric layer respectively; lower-layer air holes are formed in the first fabric layer; upper-layer air holes are formed in the third fabric layer. The environment-friendly fabric and the drying method thereof are good in occlusion property, free of chemical adhesive, good in environmental friendliness, soft in texture and comfortable to wear.
