Abstract: A degradable composite non-woven fabric being a layered structure with an upper surface layer, an intermediate fiber layer, and a lower surface layer in sequence. The upper and lower surface layers are mainly composed of degradable melt-blown fibers. The intermediate fiber layer is mainly composed of degradable water-absorbing fibers, wherein the weight of fibers of the intermediate layer accounts for more than 65% of the total weight of the composite non-woven fabric, and there are fiber interwoven regions between the upper surface layer and the intermediate fiber layer, as well as between the lower surface layer and the intermediate fiber layer.
