The utility model belongs to the field of non-woven fabrics, and particularly relates to a three-component circular fiber non-woven fabric, which consists of circular fibers, the circular fibers comprise three layers, namely an outer layer, a middle layer and an inner layer, the cross section of the inner layer is circular, the inner layer is made of PET (polyethylene terephthalate) with the melting point of 260-262 DEG C, the cross section of the middle layer is a ring, the middle layer is made of modified PET with the melting point of 240-243 DEG C, and the outer layer is made of polyester. The cross section of the outer layer is a circular ring, the outer layer is made of modified PET with the melting point of 220-223 DEG C, the outer layer is in fusion connection with the middle layer, and the middle layer is in fusion connection with the inner layer. The non-woven fabric is high in air permeability, the performance structure of the non-woven fabric cannot be damaged when the composite PTFE film is subjec
