Abstract

A breathable and waterproof non-woven fabric is manufactured by a manufacturing method including the following steps. 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 to form a mixture, in which 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. Performing a melt-blowing process on the mixture, such that the flow promoter is volatilized and a melt-blown fiber is formed, in which the melt-blown fiber has a fiber body and the water repellent disposed on the fiber body with a particle size (D90) between 350 nm and 450 nm.
