1. A breathable and waterproof non-woven fabric, manufactured by a manufacturing method, the manufacturing method comprising:
performing a kneading process on 87 to 91 parts by weight of a polyester, 5 to 7 parts by weight of a water repellent, and 3 to 6 parts by weight of a flow promoter, such that a mixture is formed, wherein the polyester has a melt index between 350 g/10 min and 1310 g/10 min at a temperature of 270° C., and the mixture has a melt index between 530 g/10 min and 1540 g/10 min at a temperature of 270° C.; and
performing a melt-blowing process on the mixture, such that the flow promoter is volatilized and a melt-blown fiber is formed, wherein the melt-blown fiber has a fiber body and the water repellent, the water repellent is disposed on a surface of the fiber body, and the water repellent has a particle size (D90) between 350 nm and 450 nm.
